FIELD OF THE DISCLOSURE
[0003] This application pertains generally to an adenoviral
vectored coronavirus antigen pharmaceutical formulation for
administration to a mammalian subject that induces an immune
response in the subject and optionally provides protection against
novel 2019 Coronavirus (SARS-CoV-2).
BACKGROUND OF THE DISCLOSURE
[0004] The coronaviruses are a diverse group of large enveloped,
positive-stranded RNA (ss RNA) viruses that cause respiratory and
enteric diseases in humans and other animals. For example, Human
coronaviruses 229E (HCoV-229E), OC43 (HCoV-OC43), NL63, and HKU1
are endemic in the human population and cause up to 30% of common
colds. Coronaviruses of animals (e.g., porcine transmissible
gastroenteritis virus (TGEV), murine hepatitis virus (MHV) and
avian infectious bronchitis virus (IBV)) cause respiratory,
gastrointestinal, neurological, or hepatic disease in their
respective hosts.
[0005] Coronavirus has a positive-sense, non-segmented,
single-stranded RNA genome, which encodes at least 18 viral
proteins (such as non-structural proteins (NSP) 1-13, structural
proteins E, M, N, S, and an RNA-dependent RNA polymerase).
Coronavirus has three major surface glycoproteins (designated S, E,
and M), and some coronaviruses have another surface glycoprotein
referred to as hemagglutinin esterase (HE), in addition, the N
(nucleocapsid) protein is a basic phosphoprotein, which is
generally associated with the genome and has been reported to be
antigenic (Holmes and Lai, Fields Virology, Chapter 34, 1996). The
S (spike) protein, a major antigen of coronavirus, has two domains:
S1, which is believed to be involved in receptor binding and S2,
believed to mediate membrane fusion between the virus and target
cell (Holmes and Lai, 1996, supra).
[0006] The S (spike) protein may form non-covalently linked
homotrimers (oligomers), which may mediate receptor binding and
virus infectivity. Homotrimers of S proteins are likely necessary
for presenting the correct native conformation of receptor binding
domains and for eliciting a neutralizing antibody response. In
addition, intracellular processing of S protein is associated with
significant posttranslation oligosaccharide modification. The
posttranslation oligosaccharide modification (glycosylation)
expected by N-glycan motif analysis indicates that the S protein
has as many as 23 sites for such modification. In addition,
C-terminal cysteine residues may also participate in protein
folding and preserving the native (functional) S protein
conformation. The S protein of some coronaviruses can be
proteolytically processed near the center of the S protein by a
trypsin-like protease in the Golgi apparatus or by extracellularly
localized enzymes into to a linked polypeptide, containing an
N-terminal S1 and a C-terminal S2 polypeptide. Presently, the
coronaviruses are subdivided into .alpha.-genus, .beta.-genus
(e.g., MERS, SARS, SARS-CoV-2), and .gamma.-genus. See FIG. 14.
[0007] Coronavirus infection is achieved through fusion of the
lipid bilayer of the viral envelope with host cell membranes.
Membrane fusion is mediated by the viral spike (S) glycoprotein on
the viral envelope. The S-glycoprotein is synthesized as a
precursor of about 180 kDa that oligomerizes in the endoplasmic
reticulum and is incorporated into budding virions in a pre-Golgi
compartment. S1 contains the receptor-binding site and thus
contributes to defining the host range of the virus. S2 is the
transmembrane subunit which contributes to mediating fusion between
viral and cellular membranes. S2 contains two 4,3-hydrophobic
repeat domains (HR) that are predicted to form coiled-coil
structures. These regions are denoted HR-1 and HR-2, and are
separated by an intervening stretch of amino acid residues called
the interhelical domain. These coiled-coil regions may play an
important role in defining the oligomeric structure of the spike
protein in its native state and its fusogenic ability.
[0008] The novel coronovirus SARS-CoV-2 (initially reported as
2019-nCoV and officially named SARS-CoV-2 by the Coronavirus Study
Group (a working group of the International Committee on Taxonomy
of Viruses) based on phylogeny, taxonomy and estabilished practice
(BioRxiv; doi.org/10.1101/2020.02.07.937862)) is a new strain that
has not been previously identified in humans and was first reported
in Wuhan, Hubei Province, China. SARS-CoV-2 is the cause of the
ongoing 2019-20 Wuhan coronavirus outbreak, a global health
emergency. Genomic sequencing has shown that it is a
positive-sense, single-stranded RNA coronavirus (GenBank Accession
No. MN908947.3; RefSeq NC_045512; "Wuhan seafood market pneumonia
virus isolate Wuhan-Hu-1"). Coronaviruses are primarily spread
through close contact, in particular through respiratory droplets
from coughs and sneezes within a range of about 6 feet (1.8 m).
Common signs of infection include respiratory symptoms, fever,
cough, shortness of breath and breathing difficulties. In more
severe cases, infection can cause pneumonia, severe acute
respiratory syndrome, kidney failure and even death. There is an
urgent need for vectors and immunogenic compositions comprising the
same that can be used to induce an immune response against
SARS-CoV-2. This disclosure addresses these issues.
SUMMARY OF THE DISCLOSURE
[0009] In some embodiments, this disclosure provides reagents,
compositions, and methods for inducing and/or improving (e.g.,
enhancing) an immune response against coronavirus, in particular
novel 2019 coronavirus SARS-CoV-2. For instance, in some
embodiments, this disclosure provides replication defective
adenoviral vectors encoding at least one SARS-CoV-2 antigen(s)
(e.g., E1A/E3 deletion human Adenovirus type 5 (hAd5)
(hAd5-SARS-CoV-2)), and/or another one or more exogenous antigens
of a different type of infectious agent (e.g., a different type of
virus such as influenza (e.g., Ad-HA)), or lacking a transgene
("hAdE"; e.g., not encoding at least one antigen or immunogen of an
exogenous infectious agent "empty"), which can be referred to
herein collectively as "SARS-CoV-2 immunization vectors". As
discussed herein, such vectors (and/or immunogenic compositions
comprising the same) can be used to induce mucosal, cell-mediated
and/or humoral immune responses against SARS-CoV-2 (e.g., against
protective SARS-CoV-2 epitopes such as spike (S) protein receptor
binding domain (RBD)). In some embodiments, this disclosure
describes the administration of such vectors (e.g., hAd5-SARS-CoV-2
and/or hAd5) to animals and/or human beings to induce and/or
enhance an immune response (e.g., the production of antibodies
and/or CD8.sup.+ T cells (and/or other T cells)) having specificity
for SARS-CoV-2 T epitope(s) (e.g., a dominant epitopes). In some
embodiments, the immune response induced by the vector administered
intranasal induce and/or enhance a T cell response with a resident
memory phenotypes in the respiratory tract. In some embodiments,
such immune response is protective against SARS-CoV-2 and/or
effective in ameliorating the symptoms and/or infection by
SARS-CoV-2, and in some embodiments can be protective against a
SARS-CoV-2 challenge. Thus, in some embodiments, this disclosure
describes the use of an immunogenic composition(s) comprising
hAd5-SARS-CoV-2 to provide solutions to art-recognized problems
regarding SARS-CoV-2 transmission and infection.
[0010] In certain embodiments provided herein are immunogenic

DETAILED DESCRIPTION
[0120] The present disclosure relates to an immunogenic composition
(e.g., vaccine) comprising an adenoviral vector encoding at least
one 2019 novel coronavirus SARS-CoV-2 antigen(s) ("a SARS-Cov-2
transgene"), compositions comprising the same, and the use thereof
for inducing a protective immune response against SARS-CoV-2.
Adenovirus is a naturally occurring respiratory virus that has been
used frequently as a vector to introduce genetic material into
cells, wherein the adenoviral vector can transduce the SARS-CoV-2
antigen genes into cells of the nasal mucosa (via intranasal
administration), leading to transient expression of the encoded
SARS-CoV-2 antigen proteins or peptides thereof in such cells.
Subsequent production of the SARS-CoV-2 antigen in normal human
epithelial cells allows for an immune response against the
SARS-CoV-2 antigen as it occurs in naturally circulating
coronavirus (e.g., SARS-CoV-2). SARS-CoV-2, initially reported as
2019-nCoV is a new and highly pathogenic virus, only emerging in
December 2019. In humans, SARS-CoV-2 is responsible for an illness
referred to as the coronavirus disease 2019 (COVID-19) as
officially defined by the World Health Organization (WHO). The
compositions disclosed herein are one of the first to target
SARS-CoV-2 and provide protection against COVID-19 and related
disease. Accordingly, the immunogenic compositions disclosed herein
provide for prevention and treatments for this new and pathogenic
SARS-CoV-2 virus, for which prior treatment did not exist and
potential for a pandemic remains. In some embodiments, the
immunogenic composition prevents and/or reduces severity of
COVID-19 as defined by FDA Guidance for Industry "Development and
Licensure of Vaccines to Prevent COVID-19" June 2020 and FDA
Guidance for Industry "Emergency Use Authorization for Vaccines to
Prevent COVID-19" October 2020, each incorporated herein by
reference. In some preferred embodiments, the immunogenic
composition reduces the incidence of infection or virologically
confirmed asymptomatic or symptomatic cases of COVID-19. In some
preferred embodiments, the immunogenic composition reduces the
incidence of severe and/or non-severe (mild or moderate) COVID-19
or the incidence of COVID-19 related hospital admissions. In some
preferred embodiments, the immunogenic composition reduces the
incidence of mild or moderate COVID-19. In some preferred
embodiments, the immunogenic composition reduces the incidence of
severe COVID-19. In some preferred embodiments, the immunogenic
composition reduces the incidence of COVID-19-related Emergency
Department visits, COVID-19 hospitalization and/or COVID-19-related
death. In some preferred embodiments, the immunogenic composition
reduces the severity of COVID-19-related diseases. In some
preferred embodiments, the immunogenic composition reduces the
transmission of SARS-CoV-2. In some preferred embodiments, the
immunogenic composition reduces the transmission of SARS-CoV-2.
[0121] In embodiments, this disclosure provides replication
defective adenoviral vectors encoding at least one SARS-CoV-2
antigen (e.g., E1A/E3 deletion human Adenovirus type 5 (hAd5)
(hAd5-SARS-CoV-2)), and/or another one or more exogenous antigens
of a different type of infectious agent (e.g., a different type of
virus such as influenza (e.g., Ad-HA)), or lacking a transgene
("hAdE"; e.g., not encoding at least one antigen or immunogen of an
exogenous infectious agent "empty"), as well as expression
cassettes, e.g., for containing and/or inserting coding sequence(s)
into vector(s), comprising a SARS-CoV-2 antigen coding sequence
encoding at least one SARS-CoV-2 antigen (and/or another or one or
more exogenous antigens of a different type of infectious agent).
Such vectors are referred to herein collectively as "SARS-CoV-2
immunization vectors". As discussed herein, such SARS-CoV-2
immunization vectors (and/or immunogenic compositions comprising
the same) are preferably used to induce mucosal, cell-mediated
and/or humoral immune responses against SARS-CoV-2 (e.g., against
protective SARS-CoV-2 epitopes such as spike (S) protein receptor
binding domain (RBD)). In some embodiments, such SARS-CoV-2
immunization vectors (and/or immunogenic compositions comprising
the same) stimulate an innate immune response supporting the
adaptive immunity of the vector if used prophylactically or
interfering directly with SARS-CoV-2 infection if administered
during the pre-exposure period (few days before infection) or
during the post-exposure period. In some embodiments, this
disclosure describes the administration of such vectors (e.g.,
hAd5-SARS-CoV-2 and/or hAd5) to animals and/or human beings to
induce and/or enhance an immune response (e.g., the production of
antibodies and/or CD8.sup.+ T cells (and/or other T cells)) having
specificity for SARS-CoV-2 T cell epitope(s) (e.g., a dominant
epitopes). In some embodiments, such immune response is protective
against SARS-CoV-2 and/or effective in ameliorating the symptoms
and/or infection by SARS-CoV-2 and/or reducing transmission of
SARS-CoV-2, and in some embodiments can be protective against a
SARS-CoV-2 challenge. Thus, in some embodiments, this disclosure
describes the use of an immunogenic composition(s) comprising
hAd5-SARS-CoV-2 to provide solutions to art-recognized problems
regarding SARS-CoV-2 transmission and infection.
[0122] In embodiments, the SARS-CoV-2 antigen can be a spike (S)
antigen or other SARS-CoV-2 antigen as disclosed herein, or as may
be otherwise available to those of ordinary skill in the art. In
certain embodiments, the SARS-CoV-2 antigen can be a full length
spike (S) protein, an immunogenic fragment thereof, or a consensus
spike (S) antigen derived from the sequences of spike antigens from
multiple strains of SARS-CoV-2 (or closely related SARS isolates)
identified during the 2019/2020 outbreak and initially sequenced

reference, along with the references cited in Fiorentini also
hereby incorporated herein by reference). In some embodiments, the
expression cassette comprising a coding sequence encoding at least
one coronavirus antigen comprises at least the S1 and/or S2 domains
of spike protein, or immunogenic fragments thereof (e.g., RBD
sequence of the S1 domain of the spike protein). See FIGS. 13, 14
and 15. In some embodiments, a pre-fusion stabilized spike protein
can be used (e.g., by introducing proline residues in S2 (HR1
domains) as shown improved expression in MERS and SARS (see U.S.
Pat. Pub. No. 2020/0061185 A1 (Graham, et al.; see, e.g., FIG. 4
thereof), substituting the wild-type amino acid sequence
NSPRRARSVAS (SEQ ID NO: 450) with NSPQQAQSVAS (SEQ ID NO: 451) at
the S1/S2 cleavage site (QQAQ mutation), KRSFIEDLLFNKVTLADA (SEQ ID
NO: 452) with KRSFIADA (SEQ ID NO: 453) at the S2' cleavage site
(fusion peptide truncation, 819-828 deletion), and/or SRLDKVEAEV
(SEQ ID NO: 454) with SRLDPPEAEV (SEQ ID NO: 455) (2P mutation,
K986P/V987P)). The use of other types of S proteins/antigens is
also contemplated herein as would be understood by those of
ordinary skill in the art. See Stabilized Spike Protein Antigen
Design section below.
[0123] In some embodiments, the expression cassette comprising a
coding sequence encoding at least one coronavirus antigen comprises
the receptor binding domain (RBD) and/or N-terminal domain (NTD) of
S1. See, e.g., FIGS. 13, 16-21. In certain embodiments, the
expression cassette comprising a coding sequence encoding SEQ ID
NO: 3 (FIG. 3A), or at least one domain sequence (e.g., B cell
epitope or T cell epitope) of SEQ ID NO: 3, or at least the RBD
domain coding sequence encoding SEQ ID NO: 446 (FIG. 3B). In
embodiments, the adenoviral vector encoding a SARS-CoV-2 antigen
may be monovalent or multivalent (i.e. one, or more than one
antigen epitope). In embodiments, the expression cassette comprises
a leader sequence (e.g., tPA) for better expression and secretion
of the encoded sequence, wherein the coding sequence is optionally
codon optimized for the mammalian subject (e.g., human). In
embodiments, the expression cassette comprises the RBD sequence
(e.g. SEQ ID NO: 446) optionally further comprising long or short
flanking sequences native to the SARS-CoV-2 virus (e.g. SEQ ID NOS:
14 and 15), which may enhance expression of the RBD in its native
globular conformation. In embodiments, the immunogenic composition
comprises one or more recombinant adenovirus, each encoding one or
more SARS-CoV-2 antigen(s).
[0124] In some embodiments, this disclosure provides compositions
and methods for inducing an immune response against coronavirus in
a mammalian subject, including human subjects. In certain
embodiments provided herein is an immunogenic composition
comprising a replication defective adenoviral vector comprising an
expression cassette comprising a coding sequence encoding at least
one coronavirus antigen or at least one immunogenic fragment
thereof. An immunogenic composition as used herein refers to any
one or more Ad-vectored compounds or agents or expressed immunogens
and/or antigens capable of priming, potentiating, activating,
eliciting, stimulating, augmenting, boosting, amplifying, or
enhancing an adaptive (specific) immune response, which may be
cellular (T cell), humoral (B cell) and/or mucosal, or a
combination thereof. The cellular response may be a peripheral T
cell response or a resident T cell response in the nasal mucosa or
respiratory tract. Also, cellular responses may preferably be
driven by CD8+ T cells and/or CD4+ T cells with an antiviral
phenotype (e.g. production interferon-gamma). Preferably, the
adaptive immune response is protective, which may include
neutralization of a virus (decreasing or eliminating virus
infectivity) and/or reduction in symptoms or viral shedding (i.e.,
transmission).
[0125] In some embodiments, this disclosure provides immunological
compositions comprising an empty (i.e., without an exogenous non-Ad
pathogen antigen encoded in the Ad5 genome) adenovirus vector (AdE)
as a therapeutic against coronavirus via activation of an innate
immune response including a mucosal innate immune response. See
Example 2. In some embodiments, a single intranasal administration
can provide protection when the AdE is administered about two to
about 20 days before exposure to SARS-Cov-2. In some embodiments,
administration of the immunogenic composition can induce increased
levels of MCP-1 and IFN-.gamma. both post-vaccination and
post-challenge, leading to the recruitment of monocytes,
neutrophils, and/or lymphocytes, which can then stimulate
production of IFN-.gamma.. In some embodiments, administration of
such immunogenic compositions can induce significant decreases
(e.g., as compared to placebo controls) in IL-1.alpha., IL-6,
and/or IL-12p70, cytokines demonstrated to mediate pulmonary
interstitial inflammation in COVID-19. See Example 7.
[0126] In some embodiments, this disclosure provides reagents
(e.g., immunogenic compositions) and methods for intranasal (i.n.)
administration of AdE vectors (i.e., replication deficient
.DELTA.E1E3 adenovirus type 5 (Ad5)) viral particles without an
exogenous non-Ad pathogen antigen encoded in the Ad5 genome) to
confer prophylactic therapy against SARS-CoV-2 in mammals,
preferably a human being. In preferred embodiments, such AdE
immunogenic compositions can be used to induce an anti-SARS-CoV-2
immune response in human beings (e.g., it is an immunogenic
composition) and demonstrate an acceptable safety profile. In
preferred embodiments, the resultant immune response is
statistically significant, and even more preferably, protective
(i.e., it is a SARS-CoV-2 vaccine). In preferred embodiments, such
AdE immunogenic compositions can be used to treat a human being
infected by SARS-CoV-2 (e.g., hospitalized patients). See Example
3.
[0127] In some embodiments, this disclosure provides an E1/E3
deleted, replication defective hAd5 comprises an expression
cassette comprising a leader sequence (e.g., tissue plasminogen
activator (tPA)) and a codon-optimized nucleotide sequence encoding
at least one SARS-CoV-2 protein(s) (e.g., any one or more of SEQ ID
NOS: 2-11, and/or one or more fragment(s) and/or derivative(s)
thereof), operably linked to a promoter (e.g., cytomegalovirus
(CMV)), immunogenic compositions and methods for using the same to
induce an immune response against SARS-CoV-2. See Example 4. In
some embodiments, the SARS-CoV-2 coding sequence are inserted into
the E1 region of the hAd5 ("hAd5-SARS-CoV-2"). In some embodiments,
the hAd5-SARS-CoV-2 can be based on a replication-deficient, E1-
and E3-deleted adenovirus type 5 vector platform (Tang et al 2009)
to express the human codon-optimized gene for the S1 domain
(residues 16 to 685 (see, e.g., Examples 14, 16)) or RBD domain
(residues 331-527 of the S1 domain (see, e.g., Examples 15, 17)) of
SARS-CoV-2 spike protein (accession number QHD43416.1 (SEQ ID NO:
3)). In preferred embodiments, such Ad5-vectored S1 and RBD
transgenes included a human tissue plasminogen activator leader
sequence and can be expressed under the control of the
cytomegalovirus immediate early promoter/enhancer (see, e.g., the
preferred embodiments of SEQ ID NO: 13 and SEQ ID NO: 15,
respectively). In some embodiments, a human being can be
intranasally (i.n.) immunized with a sufficient number of
hAd5-SARS-CoV-2 viral particles (vp) or infectious units (ifu)
(e.g., at least 1.times.10.sup.7, or at least 1.times.10.sup.8, or
at least 1.times.10.sup.9, or at least 1.times.10.sup.10, or at
least 1.times.10.sup.11 vp or ifu), such that neutralizing
antibodies are induced. In some embodiments, the hAd5-SARS-CoV-2
vaccine can induce a protective response leading to reduce disease
severity. In some embodiments, the hAdv5-SARS-CoV-2 composition can
be used to induce an anti-SARS-CoV-2 immune response in human
beings (i.e., it is an immunogenic composition), and exhibits an
acceptable safety profile. It is preferred that that immune
response be statistically significant, and even more preferably, a
protective immune response (i.e., it is a SARS-CoV-2 vaccine). In
some embodiments, such immunogenic compositions can improve the
time to clinical improvement and/or recovery in patients (e.g.,
hospitalized patients) infected with SARS-CoV-2. See Example 5. In
some embodiments, a single (or as part of a prime-boost schedule,
same or different immunogenic composition) intranasal
administration of a replication-deficient Ad5 vector expressing the
RBD domain of the Spike protein (see, e.g., preferred embodiment
SEQ ID NO: 15) stimulates the production of IgG antibodies in the
serum indicating the induction of systemic responses as well as the
production of IgG and IgA antibodies in a mammal, preferably a
human being. In preferred embodiments, animals that receive a
single administration of the high dose vaccine show the presence of
neutralizing antibodies (preferably persistent (see, e.g., Example
18) against SARS-CoV-2 as measured by focus reduction
neutralization test (FRNT) and/or induces the recruitment and/or
proliferation of innate and adaptive immune cells in different
immune compartments (see Example 13B). In preferred embodiments,
administration of such immunogenic compositions can induce systemic
and mucosal T cell immunity (e.g., in preferred embodiments a
Th-1-biased response) against SARS-CoV-2 in the mammal, preferably
a human being, as can be determined using flow cytometry (see,
e.g., Example 17). In preferred embodiments, an immunogenic
composition comprising hAd5-SARS-CoV-2, when administered as a
single intranasal dose to a mammal can induce an antibody response
against the spike protein that is durable for at least 4 months,
for at least about 5 months, at least about 6 months, at least
about 7 months, at least about 8 months, at least about 9 months,
at least about 10 months, at least about 11 months, or at least
about 12 months (one year). See Example 18. In some embodiments,
administration of the immunogenic compositions (e.g.,
hAd5-SARS-CoV-2 such as the RBD vector) can induce bone marrow and
lung resident memory antibody secreting cells in a mammal,
preferably a human being (e.g., in preferred embodiments bone
marrow and lung resident memory antibody secreting cells that
secrete both anti-spike IgG and IgA). See Example 19. In preferred
embodiments, intranasal administration of the replication
incompetent Ad5 vector expressing SARS-CoV-2 spike RBD sequence
(see, e.g., preferred embodiment SEQ ID NO: 15) can generate
humoral and cellular immune responses in both systemic and mucosal
sites, particularly within the lung, which represents a major site
for infection and clinical disease (see, e.g., Example 20).
[0128] In some embodiments, this disclosure provides methods for
intranasal (i.n.) administration of a combination of rdAd
anti-SARS-CoV-2 vectors (e.g., a "combined SARS-CoV-2 composition")
to confer prophylactic therapy against SARS-CoV-2. See Example 10.
The components of the combined SARS-CoV-2 composition (e.g., AdE,
AdD, and/or hAd5-SARS-CoV-2; "AdD" referring to
replication-defective adenoviral vector for use in treating and/or
preventing coronavirus infection can be one that does not express
one or more coronavirus antigens, but expresses one or more
antigens of a different type of infectious agent (e.g., influenza
virus); "AdE" referring to an rdAd vector for use in preventing
and/or treating coronavirus infection can be one that does not
express an exogenous antigen (exogenous as to the adenovirus from
the adenoviral vector is derived); and "rdAD" or "rdAd" referring
to replication-defective adenoviral) can be contained within a
single composition or can be contained in different compositions
that can be administered simultaneously or at different times
(e.g., as part of a prime-boost protocol) and at the same or
different sites on a subject (e.g., a mammal, preferably a human
being). Preferred prime boost protocols include the administration
of first composition to a mammal, preferably a human being,
followed by administration of a second composition an appropriate
time later (in some preferred embodiments, seven to 21 days later,
preferably 7 days later) (i.e., separate administration of the
first and second compositions), wherein the first and second
compositions comprise the same or different rdAd anti-SARS-CoV-2
vectors. In preferred embodiments, the combined SARS-CoV-2
compositions are configured to induce neutralizing antibody, IgA
and/or cellular immune response(s) and/or other response(s)
disclosed herein (e.g., avoiding or shortening the time of
hospitalization for Covid-19 a patient) against SARS-CoV-2 in a
mammalian subject, preferably a human being, to which said
immunogenic composition(s) is/are administered. In preferred
embodiments, the combined SARS-CoV-2 composition can be used to
induce an anti-SARS-CoV-2 immune response in human beings (e.g., it
is an immunogenic composition), and with an acceptable safety
profile. It is preferred that that immune response be statistically
significant, and even more preferably, a protective immune response
(i.e., it is a SARS-CoV-2 vaccine). In preferred embodiments, the
data shows the combined SARS-CoV-2 composition can be used to treat
subjects infected by SARS-CoV-2 (e.g., hospitalized patients).
[0129] In some embodiments, the combined SARS-CoV-2 composition can
comprise: a) an rdAd vector lacking a coding sequence encoding an
exogenous, non-adenoviral, antigen; b) an rdAd vector comprising an
expression cassette comprising a SARS-CoV-2 antigen coding sequence
encoding at least one SARS-CoV-2 antigen (i.e., hAd5-SARS-CoV-2),
optionally wherein said antigen comprises a SARS-CoV-2 spike (S)
protein receptor binding domain (RBD); c) an rdAd vector comprising
an expression cassette comprising a coding sequence encoding at
least one exogenous antigen of an infectious agent other than
SARS-CoV-2; d) a combination of the vectors of a) and b); e) a
combination of the vectors of b) and c); f) a combination of any of
the rdAd vectors of any of a), b), or c); and/or, g) a combination
of two different types of rdAd vectors of b) (i.e.,
hAd5-SARS-CoV-2), wherein each type comprises an expression
cassette encoding at least one SARS-CoV-2 antigen different from
that encoded by at least one other type of hAd5-SARS-CoV-2 vector
in the combination ("multivalent COVID-19 vaccine"). In some
embodiments, the components of the combined SARS-CoV-2 composition
can comprise one or both of AdE and/or AdD and/or one or more type
of hAd5-SARS-CoV-2. In some embodiments, the combined SARS-CoV-2
composition can comprise a first composition comprising AdE and/or
AdD that is administered to a human being, followed by
administration of a second composition comprising at least one type
of hAd5-SARS-CoV-2. In some embodiments, the combined SARS-CoV-2
composition can comprise at least two types of hAd5-SARS-CoV-2,
wherein each type of hAd5-SARS-CoV-2 comprises an expression
cassette encoding at least one SARS-CoV-2 antigen different from
that encoded by the other type(s) of hAd5-SARS-CoV-2 vectors in the
combination. Thus, in some embodiments, the combined SARS-CoV-2
composition can comprise a first type of hAd5-SARS-CoV-2 expressing
a first SARS-CoV-2 antigen and a second type of hAd5-SARS-CoV-2
encoding a second SARS-CoV-2 antigen, the second SARS-CoV-2 antigen
being different from the first SARS-CoV-2 antigen. In some
embodiments, the combined SARS-CoV-2 composition can comprise a
first composition comprising AdE, AdD, and/or a first type of
hAd5-SARS-CoV-2 that is administered to a human being, which is
followed by administration of a second composition comprising at
least one second type of hAd5-SARS-CoV-2, different from the first
type of hAd5-SARS-CoV-2 (or first where the first composition is
AdE or AdD) an appropriate time later (in some preferred
embodiments, seven to 21 days later, preferably 7 days later)
(i.e., separate administration of the first and second
compositions).
[0130] In some embodiments, this disclosure provides immunogenic
compositions comprising and methods for intranasal (i.n.)
administration of AdD vectors (i.e., replication deficient
.DELTA.E1E3 adenovirus type 5 (Ad5) viral particles encoding a
pathogen antigen derived from an infectious agent other than
SARS-CoV-2, e.g., influenza such as NasoVAX which is an AdVector
(Ad5) expressing influenza hemagglutinin (HA) antigen, described
in, e.g., U.S. application Ser. No. 16/840,723, filed Apr. 6, 2020,
claiming priority from U.S. application Ser. No. 62/830,444 filed 6
Apr. 2019, and published as US2020/0316188, each of which, together
with all references cited in each of these applications and
publications, is incorporated herein by reference and discloses
preparation of NasoVAX; see also U.S. Pat. Nos. 6,706,693;
6,716,823; 6,348,450; and US Patent Publications Nos. 2003/0045492;
2004/0009936; 2005/0271689; 2007/0178115; and 2012/0276138, which
may pertain to adenoviral vector(s) prepared for administration to
a mammal, which may comprise and express an influenza antigen, each
of which, with all references cited in each, being hereby
incorporated by reference) to confer prophylactic therapy against
SARS-CoV-2 (with it mentioned that while NasoVAX is a particular
product, in instances where the term "NasoVAX" is used in this
disclosure, the skilled person can read both the particular product
and also can broadly read an AdVector (Ad5), advantageously an E1
and/or E3 Ad5 vector, expressing an influenza hemagglutinin (HA)
antigen). In such embodiments, the AdD vector can induce an innate
immune response, preferably a protective immune response, against
both SARS-CoV-2 and the pathogen associated with the expressed
exogenous antigen of the AdD vector. For example, NasoVAX (or more
broadly an immunogenic composition comprising an AdD vector
expressing influenza antigen(s)) can be used to induce an immune
response against both influenza and coronavirus including
SARS-CoV-2. In this way, AdD is a dual vaccine inducing an innate
immune response against two respiratory infectious agents, and a
protective adaptive immune response against the expressed antigen.
In some embodiments, such immunogenic compositions can be
administered to patients already infected by SARS-CoV-2 and can
improve time to clinical improvement and/or recovery. In some
embodiments, then, the AdD composition can be used to induce an
anti-SARS-CoV-2 immune response in human beings (e.g., it is an
immunogenic composition) with an acceptable safety profile. It is
preferred that that immune response be statistically significant,
and even more preferably, a protective immune response (i.e., it is
a SARS-CoV-2 vaccine). In preferred embodiments, the data shows the
AdD composition can be used to treat subjects infected by
SARS-CoV-2 (e.g., hospitalized patients). In some embodiments,
NasoVAX can be used as therapy for the early phases of infection or
as a concomitant therapy for COVID-19, in some embodiments in
combination with direct antiviral agents (e.g., chloroquine,
azithromycin). See Example 7. At some juncture, the drug substance
could transition into a product in which the vector alone (e.g.,
sans a transgene as in AdE) is administered. In some embodiments,
NasoVAX can be effective in reducing rates of ICU admission and
mechanical ventilation in patients with early onset COVID-19,
and/or reduce the severity of COVID-19 in patients with early onset
COVID-19 who require hospitalization. In some embodiments, a
decrease in expression of inflammatory cytokines such as
IL-1.alpha., IL-5, IL-6, IL-12, IL-17, MCP-1, tumor necrosis factor
alpha (TNF-.alpha.), granulocyte macrophage colony stimulating
factor (GM-CSF), and/or RANTES (CCL5) (see, e.g., Example 2)
following administration of NasoVAX to subjects can occur, and can
in some embodiments be used to diagnose COVID-19, and/or predict
recovery therefrom and used to adjust treatment protocols (e.g.,
non-NasoVAX treatments) accordingly. In some embodiments, an
increase in MCP1 and/or RANTES shortly after administration of
NasoVAX, can be used to predict (e.g., as a marker) recovery from
COVID-19 and amelioration of symptoms. It is preferred that that
immune response be statistically significant, and even more
preferably, a protective immune response (i.e., it is a SARS-CoV-2
vaccine). In preferred embodiments, the data shows that NasoVAX can
be used to treat subjects infected by SARS-CoV-2 (e.g.,
hospitalized patients). In preferred embodiments, such an
immunogenic composition can be administered repeatedly (e.g., as a
seasonal vaccine administered about once every 11-14 months)
without inducing a significant immune response against the
adenoviral vector itself. See Example 9.
[0131] In some embodiments, this disclosure provides adenoviral
vectored vaccine compositions (e.g., AdD, NasoVAX) that is stable
for about 3 months at an ambient temperature, such as room
temperature (e.g., 15 to 30.degree. C., preferably 20-25.degree.
C.). In some embodiments, such adenoviral vectored vaccine
compositions can be stored, or shipped, without the need for
refrigeration or specific storage conditions. In certain
embodiments, such adenoviral vectored vaccine compositions can be
configured to induce an immune response against SARS-CoV-2 virus (a
pandemic coronavirus strain) infection and/or to ameliorate
COVID-19 disease symptoms, and may be shipped directly to the user
for administration to patients (preferably intranasal
administration). See Example 8.
[0132] In some embodiments, as shown in Example 2 herein,
administration of AdE to mice decreased the expression of certain
cytokines known to be involved in the progression and symptoms of
infectious diseases caused by viruses such as influenza. For
instance, it was shown that non-infected mice (by influenza), 25
days after administration of AdE, exhibited an increase in
expression of monocyte chemoattractant protein (MCP-1 (CCL2)),
interferon gamma (IFN-.gamma.), and RANTES (CCL5). At 28 days
post-administration of AdE, such non-infected mice exhibited
increased expression of MCP-1 and IFN-.gamma. but also a decrease
in IL-12 expression. Mice challenged with influenza at day 3
post-administration of AdE, mice were found to exhibit decreased
expression of IL-1.alpha., IL-6, IL-12, MCP-1, tumor necrosis
factor alpha (TNF-.alpha.), granulocyte macrophage colony
stimulating factor (GM-CSF), and RANTES. At day six (6)
post-administration of AdE, the infected mice exhibited decreased
expression of IL-5, IL-6, IL-12, IL-17, MCP-1 and GM-CSF, and
increased expression of macrophage inflammatory protein 1 alpha
(MIP-1.alpha. (CCL3)) and RANTES (CCL5). These results are
consistent with the development of a "cytokine storm" during
infection by SARS-CoV-2. In some embodiments, then, to prevent
and/or treat SARS-CoV-2 infection by, for instance, inhibiting the
development of or suppressing a cytokine storm, a SARS-CoV-2
immunogenic composition is administered to a human being with one
or more anti-cytokine reagent(s) (e.g., one or more anti-IL-1a
reagent(s), one or more anti-IL5 reagent(s), one or more anti-IL-6
reagent(s), one or more anti-IL-12 reagent(s), one or more
anti-IL-17 reagent(s), one or more anti-MCP-1 reagent(s), one or
more anti-TNF-.alpha. reagent(s), one or more anti-GM-CSF
reagent(s), and/or one or more anti-RANTES reagent(s). See Example
11. In some embodiments, the one or more anti-cytokine reagents
would not include one or more anti-MIP.alpha. reagent(s) and/or one
or more anti-RANTES reagent(s). Exemplary anti-cytokine reagents
that can be used as described herein can include, for example, any
of those shown in Table 1 herein. In some embodiments, such
anti-cytokine reagents can be administered with the SARS-CoV-2
immunogenic composition at the same time (i.e., simultaneously), or
essentially the same time, by a suitable route appropriate for each
reagent (e.g., intranasal administration of the SARS-CoV-2
immunogenic composition and subcutaneous injection for the
anti-cytokine reagent(s)) in effective amounts. In some
embodiments, the one or more anti-cytokine reagent(s) can be
co-administered with the SARS-CoV-2 composition and, in some
embodiments, the one or more anti-cytokine reagents are
subsequently administered as the sole active agents. In preferred
embodiments, the combination of SARS-CoV-2 composition(s) and one
or more anti-cytokine reagent(s) can be useful for inducing an
anti-SARS-CoV-2 immune response in human beings (e.g., it is an
immunogenic composition), with an acceptable safety profile, and
with alleviation of symptoms related to the deleterious effects of
cytokines experienced by some patients (e.g., the aforementioned
cytokine storm). In preferred embodiments, the immune response be
statistically significant, and even more preferably, that it is a
protective and/or curative immune response (i.e., it is a
SARS-CoV-2 vaccine). In preferred embodiments, the combination of
SARS-CoV-2 composition(s) and one or more anti-cytokine reagent(s)
can be used to treat subjects infected by SARS-CoV-2 (e.g.,
hospitalized patients).
[0133] As described herein, the S protein (spike protein)
immunogen, fragments, and variants thereof described herein contain
one or more epitopes that elicit or induce an immune response,
preferably a protective immune response, which may be a humoral
response, a mucosal IgA response and/or a cell-mediated immune
response. A protective immune response may be manifested by at
least one of the following: preventing infection of a host by a
coronavirus; modifying or limiting the infection; aiding,
improving, enhancing, or stimulating recovery of the host from
infection; and generating immunological memory that will prevent or
limit a subsequent infection by a coronavirus. A humoral response
may include production of antibodies that neutralize infectivity,
lyse the virus and/or infected cell, facilitate removal of the
virus by host cells (for example, facilitate phagocytosis), and/or
bind to and facilitate removal of viral antigenic material. An
antibody response may also include a mucosal response, which
comprises eliciting or inducing a specific mucosal IgA response. In
certain embodiments is provided a method for inducing a combined
mucosal, humoral and/or cell-mediated protective immune response in
a human subject against SARS-CoV-2 infection.
[0134] Provided herein are pharmaceutically acceptable compositions
(which may also be referred to as formulations) suitable and/or
configured for intranasal administration to a mammalian subject and
that are configured to induce an immune response against an antigen
(e.g., an immunogen), and optionally induce a protective immune
response (i.e., as a vaccine). In some embodiments, the
pharmaceutical formulation is an immunogenic composition that upon
administration induces an immune response against an antigen in a
mammalian subject. In some embodiments, the pharmaceutical
formulation is a vaccine or therapeutic composition configured to
induce a protective immune response in a mammalian subject, which
is protective against foreign infectious agents, and in preferred
embodiments induce or stimulate a protective response against
SARS-CoV-2 infection.

which is in any prior-filed but not prior published patent
application or patent is explicitly reserved (with "prior-filed but
not prior published" being relative to the filing date accorded
this disclosure). Nothing herein is to be construed as a promise.
Nor is any citation or identification of any document in this
application an admission that such document is available as prior
art.
[0139] It should also be noted that, as used in this specification
and the appended claims, the term "configured" describes a system,
apparatus, or other structure that is constructed or configured to
perform a particular task or adopt a particular configuration. The
term "configured" can be used interchangeably with other similar
phrases such as arranged and configured, constructed and arranged,
adapted and configured, adapted, constructed, manufactured and
arranged, and the like.
[0140] As used herein, an "adjuvant" refers to a substance that
enhances the body's immune response to an antigen. In embodiments,
the present monovalent influenza pharmaceutical formulation is a
non-adjuvanted vaccine composition.
[0141] By "administration" is meant introducing an immunogenic or
vaccine composition of the present disclosure into a subject; it
may also refer to the act of providing a composition of the present
disclosure to a subject (e.g., by prescribing or
administering).
[0142] As used herein, the term "ambient temperature" is the air
temperature for storing the present monovalent influenza
pharmaceutical formulation. In embodiments, the ambient temperature
is a room temperature, such as selected from any temperature within
the range from about 15 to 30.degree. C., preferably from about 20
to 25.degree. C.
[0143] The term "therapeutically effective amount" as used herein
refers to that amount of the compound being administered which will
induce a combined, mucosal, humoral and cell mediated immune
response. The term also refers to an amount of the present
compositions that will relieve or prevent to some extent one or
more of the symptoms of the condition to be treated. In reference
to conditions/diseases that can be directly treated with a
composition of the disclosure, a therapeutically effective amount
refers to that amount which has the effect of preventing the
condition/disease from occurring in a mammal that may be
predisposed to the disease but does not yet experience or exhibit
symptoms of the condition/disease (prophylactic treatment),
alleviation of symptoms of the condition/disease, diminishment of
extent of the condition/disease, stabilization (e.g., not
worsening) of the condition/disease, preventing the spread of
condition/disease, delaying or slowing of the condition/disease
progression, amelioration or palliation of the condition/disease
state, and combinations thereof. The term "effective amount" refers
to that amount of the compound being administered which will
produce a reaction (e.g., a protective immune response and/or as
provided by a vaccine) that is distinct from a reaction that would
occur in the absence of the compound.
[0144] As used herein, the term "percent (%) homology" or "percent
(%) identity" and grammatical variations thereof in the context of
two sequences (e.g., protein sequences), refers to two or more
sequences or subsequences (i.e., fragment thereof) that have at
least about 75%, 76%, 77%, 78%, 79%, 80%, 81%, 82%, 83%, 84%, 85%,
86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%,
99%, and/or 100% nucleotide or amino acid residue identity
(homology), when compared and aligned for maximum correspondence,
as measured using one of the well-known sequence comparison
algorithms or by visual inspection. A nonlimiting example of a
mathematical algorithm used for comparison of two sequences is the
algorithm of Karlin & Altschul, Proc. Natl. Acad. Sci. USA
1990; 87: 2264-2268, modified as in Karlin & Altschul, Proc.
Natl. Acad. Sci. USA 1993; 90: 5873-5877. Another example of a
mathematical algorithm used for comparison of sequences is the
algorithm of Myers & Miller, CABIOS 1988; 4: 11-17. Such an
algorithm is incorporated into the ALIGN program (version 2.0)
which is part of the GCG sequence alignment software package. When
utilizing the ALIGN program for comparing amino acid sequences, a
PAM120 weight residue table, a gap length penalty of 12, and a gap
penalty of 4 can be used. Yet another useful algorithm for
identifying regions of local sequence similarity and alignment is
the FASTA algorithm as described in Pearson & Lipman, Proc.
Natl. Acad. Sci. USA 1988; 85: 2444-2448. Advantageous for use is
the WU-BLAST (Washington University BLAST) version 2.0 software.
WU-BLAST version 2.0 executable programs for several UNIX platforms
can be downloaded from ftp://blast.wustl.edu/blast/executables.
This program is based on WU-BLAST version 1.4, which in turn is
based on the public domain NCBI-BLAST version 1.4 (Altschul &
Gish, 1996, Local alignment statistics, Doolittle ed., Methods in
Enzymology 266: 460-480; Altschul et al., Journal of Molecular
Biology 1990; 215: 403-410; Gish & States, 1993; Nature
Genetics 3: 266-272; Karlin & Altschul, 1993; Proc. Natl. Acad.
Sci. USA 90: 5873-5877; all of which are incorporated by reference
herein). In addition, from this definition, when this disclosure
speaks about percent (%) homology, the reader can also understand
percent (%) identity. In addition, it should be understood that
proteins within this invention may differ from the exact sequences
illustrated and described in this disclosure. Thus, the invention
contemplates deletions, additions and substitutions to the
sequences shown, so long as the sequences function in accordance
with the methods of the invention. In this regard, particularly
preferred substitutions will generally be conservative in nature,
i.e., those substitutions that take place within a family of amino
acids. For example, amino acids are generally divided into four
families: (1) acidic-aspartate and glutamate; (2) basic-lysine,
arginine, histidine; (3) non-polar-alanine, valine, leucine,
isoleucine, proline, phenylalanine, methionine, tryptophan; and (4)
uncharged polar-glycine, asparagine, glutamine, cysteine, serine
threonine, tyrosine. Phenylalanine, tryptophan, and tyrosine are
sometimes classified as aromatic amino acids. It is reasonably
predictable that an isolated replacement of leucine with isoleucine
or valine, or vice versa; an aspartate with a glutamate or vice
versa; a threonine with a serine or vice versa; or a similar
conservative replacement of an amino acid with a structurally
related amino acid, will not have a major effect on the biological
activity. Proteins having substantially the same amino acid
sequence as the sequences illustrated and described but possessing
minor amino acid substitutions that do not substantially affect the
immunogenicity of the protein are, therefore, within the scope of
the invention. Nucleic acid sequences within the invention, as to
such proteins, will similarly vary from this explicitly disclosed
herein. The invention thus encompasses nucleotide sequences
encoding functionally and/or antigenically equivalent variants and
derivatives of the antigens or proteins herein disclosed and
functionally equivalent fragments thereof. These functionally
equivalent variants, derivatives, and fragments display the ability
to retain antigenic activity. For instance, changes in a DNA
sequence that do not change the encoded amino acid sequence, as
well as those that result in conservative substitutions of amino
acid residues, one or a few amino acid deletions or additions, and
substitution of amino acid residues by amino acid analogs are those
which will not significantly affect properties of the encoded
polypeptide. Conservative amino acid substitutions are
glycine/alanine; valine/isoleucine/leucine; asparagine/glutamine;
aspartic acid/glutamic acid; serine/threonine/methionine;
lysine/arginine; and, phenylalanine/tyrosine/tryptophan.
[0145] As used herein, the term "human adenovirus" is intended to
encompass all human adenoviruses of the Adenoviridae family, which
include members of the Mastadenovirus genera. To date, over
fifty-one human serotypes of adenoviruses have been identified
(see, e.g., Fields et al., Virology 2, Ch. 67 (3d ed.,
Lippincott-Raven Publishers)). The adenovirus may be of serogroup
A, B, C, D, E, or F. The human adenovirus may be a serotype 1 (Ad
1), serotype 2 (Ad2), serotype 3 (Ad3), serotype 4 (Ad4), serotype
5 (Ad5), serotype 6 (Ad6), serotype 7 (Ad7), serotype 8 (Ad8),
serotype 9 (Ad9), serotype 10 (Ad10), serotype 11 (Ad11), serotype
12 (Ad12), serotype 13 (Ad13), serotype 14 (Ad14), serotype 15
(Ad15), serotype 16 (Ad16), serotype 17 (Ad17), serotype 18 (Ad18),

serotype 20 (Ad20), serotype 21 (Ad21), serotype 22 (Ad22),
serotype 23 (Ad23), serotype 24 (Ad24), serotype 25 (Ad25),
serotype 26 (Ad26), serotype 27 (Ad27), serotype 28 (Ad28),
serotype 29 (Ad29), serotype 30 (Ad30), serotype 31 (Ad31),
serotype 32 (Ad32), serotype 33 (Ad33), serotype 34 (Ad34),
serotype 35 (Ad35), serotype 36 (Ad36), serotype 37 (Ad37),
serotype 38 (Ad38), serotype 39 (Ad39), serotype 40 (Ad40),
serotype 41 (Ad41), serotype 42 (Ad42), serotype 43 (Ad43),
serotype 44 (Ad44), serotype 45 (Ad45), serotype 46 (Ad46),
serotype 47 (Ad47), serotype 48 (Ad48), serotype 49 (Ad49),
serotype 50 (Ad50), serotype 51 (Ad51), or combinations thereof,
but are not limited to these examples. In certain embodiments, the
adenovirus is serotype 5 (Ad5).
[0146] As used herein, an "immunogenic composition" refers to a
composition, typically comprising at least one type of replication
defective adenoviral vector as disclosed herein and at least one
pharmaceutically acceptable carrier, that when administered to a
host induces and/or enhances an immune response against an antigen
and/or infectious agent against which such immune response is
directed (e.g., an antigen encoded by a replication defective
adenoviral vector, and/or as may be induced/enhanced by an "empty"
hAd5 vector). A "vaccine" refers to such an immunogenic composition
that when administered induces a protective immune response against
an infectious agent (e.g., protects the host against challenge with
the infectious agent). In certain embodiments, an immunogenic
composition (e.g., vaccine) can comprise one or more viral
vector(s) containing and/or expressing an antigen, along with other
components of an immunogenic composition (e.g., vaccine) suitable
for administration to a mammalian host, including for example one
or more adjuvants, slow release compounds, solvents, buffers, etc.
In certain embodiments, an immunogenic composition and/or vaccine
can comprise a protein and/or carbohydrate and/or lipid and/or
other antigen, including but not limited to one or more killed
antigen(s) (e.g., a killed or completely inactive virus) or a live
attenuated antigen (e.g., an attenuated virus). In some
embodiments, the immunogenic composition(s) and/or vaccine(s)
improve immune responses to any antigen regardless of the antigen
source or its function.
[0147] As used herein, a "pharmaceutically acceptable carrier"
refers to a carrier or diluent that does not cause significant
irritation to the human subject and does not abrogate the
biological activity and properties of the administered immunogenic
or vaccine compositions.
[0148] As used here, the term "seroconversion" is defined as a
4-fold or greater increase in serum neutralization antibody titers
(e.g., anti-S1/S2 antibody or anti-RBD of 51 antibody) after
vaccination (e.g., administration of a present immunogenic or
vaccine composition).
[0149] As used herein, the term "seropositive" means a measurable
(e.g., detectable in an in vitro assay) in serum neutralization
antibody after vaccination (e.g., administration of a present
immunogenic composition).
[0150] As used herein, the term "protection" indicates that a
protective immune response has been elicited, and a protective
immune response may be manifested by at least one of the following:
preventing infection of a host by a coronavirus; modifying or
limiting the infection; aiding, improving, enhancing, or
stimulating recovery of the host from infection; and generating
immunological memory that will prevent or limit a subsequent
infection by a coronavirus. A humoral response may include
production of antibodies that neutralize infectivity, lyse the
virus and/or infected cell, facilitate removal of the virus by host
cells (for example, facilitate phagocytosis), and/or bind to and
facilitate removal of viral antigenic material. An antibody
response may also include a mucosal response, which comprises
eliciting or inducing a specific mucosal IgA response. As used
herein, the term "seroprotected" means a subject post vaccination
that is protected from infection via generation of serum
neutralization antibodies. In a population, this is referred to as
a percentage (%) of seroprotected individuals (e.g., 50%). In
embodiments, the present immunogenic compositions and methods of
use provide seroprotection to the mammalian subject, such as a
human subject, against SARS-CoV-2 infection. The duration of
protection can be at least about one month to at least about 14
months. Seroprotection can last at least about 1 month, 2 months, 4
months, 6 months, 8 months, 10 months, 12 month or at least about
13 months.
[0151] The terms "treat", "treating", and "treatment" are an
approach for obtaining beneficial or desired clinical results.
Specifically, beneficial or desired clinical results include, but
are not limited to, alleviation of symptoms, diminishment of extent
of disease, stabilization (e.g., not worsening) of disease,
delaying or slowing of disease progression, substantially
preventing spread of disease, amelioration or palliation of the
disease state, and remission (partial or total) whether detectable
or undetectable. In addition, "treat", "treating", and "treatment"
can also mean prolonging survival as compared to expected survival
if not receiving treatment and/or can be therapeutic in terms of a
partial or complete cure for a disease and/or adverse effect
attributable to the disease. As used herein, the terms
"prophylactically treat" or "prophylactically treating" refers
completely, substantially, or partially preventing a
disease/condition or one or more symptoms thereof in a host.
Similarly, "delaying the onset of a condition" can also be included
in "prophylactically treating" and refers to the act of increasing
the time before the actual onset of a condition in a patient that
is predisposed to the condition.
[0152] In this disclosure, a "vaccine" advantageously refers to a
composition comprising a replication defective adenoviral vector
containing and expressing a coronavirus antigen or other infectious
agent, and/or lacking a coding sequence for an exogenous antigen
(e.g., empty Advector), along with other components of a vaccine
formulation, including for example adjuvants, slow release
compounds, solvents, etc., for inducing a protective immune
response. Such compositions within this disclosure that comprise a
replication defective adenoviral vector containing and expressing a
coronavirus antigen or other infectious agent, and/or lacking a
coding sequence for an exogenous antigen (e.g., empty Advector),
along with other components of a vaccine formulation, including for
example adjuvants, slow release compounds, solvents, etc. can also
be for inducing an immune response, and are within "immunogenic
compositions" herein-discussed. In embodiments of the invention,
vaccines or immunogenic compositions can improve immune responses
to any antigen regardless of the antigen source or its
function.
[0153] As referred to herein, a "vector" carries a genetic code, or
a portion thereof, for an antigen, however it is not the antigen
itself. In an exemplary aspect, a vector can include a viral
vector, such as an adenoviral vector. As referred to herein an
"antigen" means a substance that induces and/or enhances a specific
immune response against the antigen, and/or an infectious agent
expressing such antigen, in a subject, including humans and/or
animals. The antigen may comprise a whole organism, killed,
attenuated or live; a subunit or portion of an organism; a
recombinant vector containing an insert with immunogenic
properties; a piece or fragment of DNA capable of inducing an
immune response upon presentation to a host animal; a polypeptide,
an epitope, a hapten, or any combination thereof. In various
aspects, the antigen is a virus, bacterium, a subunit of an
organism, an auto-antigen, or a cancer antigen.
[0154] Ranges may be expressed herein as from about one particular
value, and/or to about another particular value. When such a range
is expressed, another aspect includes from the one particular value
and/or to the other particular value. Similarly, when values are
expressed as approximations, by use of the antecedent about or
approximately, it will be understood that the particular value
forms another aspect. It will be further understood that the
endpoints of each of the ranges are significant both in relation to
the other endpoint, and independently of the other endpoint. Ranges
(e.g., 90-100%) are meant to include the range per se as well as
each independent value within the range as if each value was
individually listed.
[0155] Immunogenic Compositions and Vaccines
[0156] Provided herein are replication-defective adenoviral
("rdAd") vector and immunogenic compositions comprising the same,
(in some embodiments vaccine formulations) suitable and/or
configured for administration to a mammalian subject for the
prevention and/or treatment of coronavirus infection ("coronavirus
pharmaceutical formulations"), preferably wherein the coronavirus
is SARS-CoV-2. In some embodiments, any adenoviral vector
(Ad-vector) known to one of skill in art, and prepared for
administration to a mammal, which may comprise and express a
coronavirus antigen, preferably a SARS-CoV-2 antigen, but also may
not express an exogenous (i.e., non-Ad) antigen, or may be an empty
AdVector (e.g., no exogenous antigen transgene) may be used in the
compositions and with the methods of this application. Such
Ad-vectors include any of those known to those of ordinary skill in
the art including but not limited to those described in U.S. Pat.
Nos. 6,706,693; 6,716,823; 6,348,450; and/or US Patent Publication
Nos. 2003/0045492; 2004/0009936; 2005/0271689; 2007/0178115;
and/or, 2012/0276138; all of which being incorporated herein
incorporated by reference in their entireties. In certain
embodiments, the non-replicating adenoviral viral vector (rdAd) is
a human adenovirus. In alternative embodiments, the adenovirus is a
bovine adenovirus, a canine adenovirus, a non-human primate
adenovirus (e.g., chimp), a chicken adenovirus, or a porcine or
swine adenovirus. In exemplary embodiments, the non-replicating
viral vector is a human adenovirus. In some embodiments, the
non-replicating adenoviral vectors are particularly useful for gene
transfer into eukaryotic cells and immunogenic composition (e.g.,
vaccine) development, and in animal models.
[0157] In certain embodiments the recombinant adenovirus vector may
be non-replicating or replication-deficient (RD) requiring
complementing E1 activity for replication. In embodiments the
recombinant adenovirus vector may include E1-defective,
E3-defective, and/or E4-defective adenovirus vectors, or the
"gutless" adenovirus vector in which viral genes are deleted. The
E1 mutation raises the safety margin of the vector because
E1-defective adenovirus mutants are replication incompetent in
non-permissive cells. The E3 mutation enhances the immunogenicity
of the antigen by disrupting the mechanism whereby adenovirus
down-regulates MHC class I molecules. The E4 mutation reduces the
immunogenicity of the adenovirus vector by suppressing the late
gene expression, thus may allow repeated re-vaccination utilizing
the same vector. In exemplary embodiments, the recombinant
adenovirus vector is an E1 and E3 defective vector. The "gutless"
adenovirus vector replication requires a helper virus and a special
human 293 cell line expressing both E1a and Cre, a condition that
does not exist in natural environment; the vector is deprived of
viral genes, thus the vector as an immunogenic composition (e.g.,
vaccine) carrier is non-immunogenic and may be inoculated for
multiple times for re-vaccination. The "gutless" adenovirus vector
also contains 36 kb space for accommodating transgenes, thus
allowing co-delivery of a large number of antigen genes into cells.
Specific sequence motifs such as the RGD motif may be inserted into
the H-I loop of an adenovirus vector to enhance its infectivity. An
adenovirus recombinant may be constructed by cloning specific
transgenes or fragments of transgenes into any of the adenovirus
vectors such as those described below. The adenovirus recombinant
vector is used to transduce epidermal cells of a vertebrate in a
non-invasive mode for use as an immunizing agent. The adenovirus
vector may also be used for invasive administration methods, such
as intravenous, intramuscular, or subcutaneous injection.
[0158] In some embodiments, such an rdAd vector for use in
preventing and/or treating coronavirus infection can be one that
does not express an exogenous antigen (exogenous as to the
adenovirus from the adenoviral vector is derived), such vectors
being referred to herein as "AdE" vectors. In some embodiments, the
replication-defective adenoviral vector for use in treating and/or
preventing coronavirus infection can be one that does not express
one or more coronavirus antigens, but expresses one or more
antigens of a different type of infectious agent (e.g., influenza
virus) (referred to herein as "AdD"). In certain embodiments is
provided an immunogenic composition comprising a rdAd vector
comprising an expression cassette comprising a coding sequence
encoding at least one SARS-CoV-2 antigen, referred to herein as
hAd5-SARS-CoV-2 vectors. In some embodiments, the immunogenic
compositions of this disclosure can comprise a different type of
such vectors (e.g., AdE, or AdD), alone or in combination with
hAd5-SARS-CoV-2 vectors. In some embodiments, these types of
vectors can be collectively, or a subset of at least two such
vectors, referred to as "rdAd anti-SARS-CoV-2 vectors". A
SARS-CoV-2 immunogenic composition (e.g., vaccine) is a
pharmaceutical formulation comprising one or more such rdAd
anti-SARS-CoV-2 vectors.
[0159] An AdE vector is a rdAd vector that does not encode an
exogenous antigen (i.e., an antigen exogenous as to the adenovirus
from the adenoviral vector is derived, e.g., an antigen of a
different type of infectious agent such as influenza). Such hAd5
vectors can also be referred to as "empty", lacking an exogenous
transgene, and/or being "transgene-free". In some embodiments, an
AdE vector can be a .DELTA.E1E3 Ad5 vector (e.g., lacking the E1
region of the viral genome (nucleotides 343 to 3511) and
nucleotides 28132 to 30813 in the E3 region). This disclosure
provides some embodiments, comprising immunogenic compositions
comprising AdE vectors (including AdE viral particles) and the use
of such immunogenic compositions to prevent and/or treat
coronavirus infection, preferably wherein the coronavirus is
SARS-CoV-2, and methods for doing so. In some embodiments, such AdE
vectors can be co-administered with one or more other rdAd
anti-SARS-CoV-2 vectors. In some embodiments, such
co-administration can refer to administration of a single
immunogenic composition comprising AdE vectors and one or more rdAd
anti-SARS-CoV-2 vectors, and/or essentially simultaneous and/or
sequential administration of multiple immunogenic compositions
comprising AdE vectors and another immunogenic composition
comprising one or more other rdAd anti-SARS-CoV-2 vectors. Such AdE
vectors can also be administered as part of a prime-boost protocol,
in which an immunogenic composition comprising AdE is administered
before or after (e.g., 7-28 days before and/or after)
administration of an immunogenic composition comprising one or more
other types of rdAd anti-SARS-CoV-2 vectors. In some embodiments,
this disclosure provides methods for inducing (and/or enhancing) an
immune response against SARS-CoV-2 in a mammalian subject in need
thereof by administering (e.g., intranasally) an effective amount
of such composition(s) (e.g., at least about 10.sup.7 infectious
units (ifu) or virus particles (vp) (e.g., at least
1.times.10.sup.7, or at least 1.times.10.sup.8, or at least
1.times.10.sup.9, or at least 1.times.10.sup.10, or at least
1.times.10.sup.11 vp or ifu of AdE and, where present, at least one
other rdAd anti-SARS-CoV-2 vectors). In some embodiments, the
immune response against SARS-CoV-2 induced or enhanced by
administration of such immunogenic compositions preferably begins
within about twenty-four hours of administration and preferably
lasts for at least about 21 days. In preferred embodiments, such
methods comprise intranasal administration of such immunogenic
compositions in an effective amount of (e.g., at least about
10.sup.7 ifu of the AdE and, where present, at least one other rdAd
anti-SARS-CoV-2 vectors). In preferred embodiments, the second rdAd
anti-SARS-CoV-2 vector encodes at least one heterologous antigen of
SARS-CoV-2 and/or at least one other infectious agent (e.g., AdD),
thereby providing a drug-vaccine duo regimen. In some embodiments,
the administering of multiple doses of AdE vectors (and/or other
rdAd anti-SARS-CoV-2 vectors) can be about any of 7, 10, 14, 21,
28, 35, 42, 49, or 56 days apart. Preferably, such immunogenic
compositions can be administered intranasally. In some embodiments,
the host is an animal, such as an adult or child human being,
optionally wherein the host is immunocompromised. In preferred
embodiments, the immune response against the coronavirus lasts for
at least about 40-50 days, and can be re-initiated by
re-administration of AdE with or without the one or more SARS-CoV-2
vectors. Other embodiments of such AdE vectors, immunogenic
compositions, and/or methods are also contemplated herein as would
be understood by those of ordinary skill in the art.
[0160] An AdD vector is a rdAd vector that encodes an exogenous
antigen of an infectious agent other than coronavirus and/or
SARS-CoV-2 (e.g., an antigen of a different type of infectious
agent such as influenza (e.g., swine influenza, seasonal influenza,
avian influenza, H1N1 influenza, or H5N1 influenza). In some
embodiments, an AdD vector can be a .DELTA.E1E3 Ad5 vector encoding
at least one heterologous (e.g., non-Ad) antigen, preferably
optimized for expression in a host (e.g., a mammal). Representative
examples of antigens which can be used to produce an immune
response against SARS-CoV-2 using the methods described herein can
include influenza hemagglutinin, influenza nuclear protein,
influenza M2, tetanus toxin C-fragment, anthrax protective antigen,
anthrax lethal factor, rabies glycoprotein, HBV surface antigen,
HIV gp 120, HIV gp 160, human carcinoembryonic antigen, malaria
CSP, malaria SSP, malaria MSP, malaria pfg, and Mycobacterium
tuberculosis HSP, etc. In one embodiment, an AdD vector can be the
AdNC.H1.1 vector encoding the A/New Caledonia/20/99 H1N1 IFV (NC20)
HA1 domain (see, e.g., Tang et al. Expert Rev Vaccines 8: 469-481
(2009)). In one embodiment, the AdD vector can contain a genetic
insert encoding the hemaglutinnin (HA) surface protein antigen from
an A/California/04/2009(H1N1)-like strain of influenza (AdcoCA09.HA
"NasoVAX"), preferably manufactured by propagation in
replication-permissive PER.C6 cells, followed by purification of
the virus from the infected cell harvest, and prepared as a final
product including the following excipients: Tris HCl (pH 7.4),
histidine, sucrose, sodium chloride, magnesium chloride,
polysorbate 80, ethylenediaminetetraacetic acid, and ethanol. This
disclosure provides some embodiments, that comprise immunogenic
compositions comprising AdD vectors (including AdD viral particles)
and the use of such immunogenic compositions to prevent and/or
treat coronavirus infection, preferably wherein the coronavirus is
SARS-CoV-2, and methods for doing so. In some embodiments, such AdD
vectors can be co-administered with one or more other rdAd
anti-SARS-CoV-2 vectors. In some embodiments, such
co-administration can refer to administration of a single
immunogenic composition comprising AdD vectors and one or more rdAd
anti-SARS-CoV-2 vectors, and/or essentially simultaneous and/or
sequential administration of multiple immunogenic compositions
comprising AdD vectors and another immunogenic composition
comprising one or more other rdAd anti-SARS-CoV-2 vectors. Such AdD
vectors can also be administered as part of a prime-boost protocol,
in which an immunogenic composition comprising AdD vectors (e.g.,
as viral particles) is administered before or after (e.g., 7-21
days before and/or after) administration of an immunogenic
composition comprising one or more other types of rdAd
anti-SARS-CoV-2 vectors. In some embodiments, this disclosure
provides methods for inducing (and/or enhancing) an immune response
against SARS-CoV-2 in a mammalian subject in need thereof by
administering (e.g., intranasally) an effective amount of such
composition(s) (e.g., at least about 10.sup.7 viral particles (vp)
or infectious units (ifu) (e.g., at least 1.times.10.sup.7, or at
least 1.times.10.sup.8, or at least 1.times.10.sup.9, or at least
1.times.10.sup.10, or at least 1.times.10.sup.11 vp or ifu) of each
of the AdD vector and, where present, at least one other rdAd
anti-SARS-CoV-2 vectors). In some embodiments, the immune response
against SARS-CoV-2 induced or enhanced by administration of such
immunogenic compositions preferably begins within about twenty-four
hours of administration and preferably lasts for at least about 21
days. In preferred embodiments, such methods comprise intranasal
administration of such immunogenic compositions in an effective
amount of (e.g., at least about 10.sup.7 vp or ifu (e.g., at least
1.times.10.sup.7, or at least 1.times.10.sup.8, or at least
1.times.10.sup.9, or at least 1.times.10.sup.10, or at least
1.times.10.sup.11 vp or ifu) of each of the AdD vector and, where
present, at least one other rdAd anti-SARS-CoV-2 vectors). In
preferred embodiments, the second rdAd anti-SARS-CoV-2 vector is
AdE and/or encodes at least one heterologous antigen of SARS-CoV-2
and/or at least one other infectious agent, thereby providing a
drug-vaccine duo regimen. In some embodiments, the administering of
multiple doses of AdD vectors (and/or other rdAd anti-SARS-CoV-2
vectors) can be about any of 7, 10, 14, 21, 28, 35, 42, 49, or 56
days apart. Preferably, such immunogenic compositions can be
administered intranasally. In some embodiments, the host is an
animal, such as an adult or child human being, optionally wherein
the host is immunocompromised. In preferred embodiments, the immune
response against the coronavirus lasts for at least about 40-50
days, and can be re-initiated by re-administration of AdD with or
without the one or more SARS-CoV-2 vectors. Other embodiments of
such AdD vectors, immunogenic compositions comprising the same,
and/or methods for using the same are also contemplated herein as
would be understood by those of ordinary skill in the art.
[0161] In some embodiments, this disclosure provides an immunogenic
composition comprising one or more SARS-CoV-2 vectors comprising a
rdAd vector comprising an expression cassette comprising a coding
sequence encoding at least one SARS-CoV-spike (S) protein receptor
binding domain (RBD), or at least one immunogenic fragment thereof,
wherein the composition is configured to induce neutralizing
antibody to the spike protein RBD, in a mammalian subject. Putative
studies indicate the spike protein via its receptor binding domain
of S1 binds to the angiotensin-converting enzyme 2 (ACE2) receptor
(Y. Wan et al.; receptor recognition by novel coronavirus from
Wuhan: An analysis based on decade-long structural studies of SARS;
J. Virol. doi:10.1128/JVI.00127-20; posted online 29 Jan. 2020).
Generating an immune response against at least the RBD of spike
protein is an attractive target for inducing neutralization
antibodies, wherein spike protein mediates coronavirus entry into
host cells by first binding to a host receptor (e.g., ACE2) and
then fusing viral and host membranes. The spike protein for
SARS-CoV-2 is provided herein as SEQ ID NO: 3 (GenBank:
QHD43416.1). See FIG. 3.
[0162] In certain embodiments, the immunogenic composition (e.g.
vaccine) comprises one or more coronavirus antigens. In certain
embodiments, the coronavirus is SARS-CoV-2, wherein the coding
sequence for the Wuhan 2019 isolate (SARS-CoV-2) is provided herein
as SEQ ID NO: 1. In embodiments, the replication deficient
adenoviral vector comprises one or more coding sequences of SEQ ID
NO: 1. Those sequences comprise one or more immunogenic domains
such as a B cell and/or T cell epitope. In certain embodiments, the
replication deficient adenoviral vector comprises and/or expresses
(e.g., comprises an expression cassette encoding) one or more
immunogenic domains provided in any of encoded SEQ ID NO: 2 to 20.
In preferred embodiments, the replication deficient adenoviral
vector comprises and/or expresses (e.g., comprises an expression
cassette encoding) SEQ ID NO: 15, or a variant thereof (i.e., in
either the RBD sequence (amino acids 57-253 of SEQ ID NO: 15
(comprising SEQ ID NO: 446)), and/or the signal and/or leader
and/or flanking sequences). In embodiments, the coding sequence of
the replication deficient adenovirus vector encodes at least one or
more B cell epitopes, one or more CD8.sup.+ T cell epitopes, and/or
one or more CD4.sup.+ T cell epitopes. One of skill in the art
understands how to identify those epitopes within a larger sequence
using bioinformatic methodologies such as publicly available tools
accessible at the immune epitope database (IEDB), in vitro assay
based on PBMCs from infection-positive subjects combined with short
linear peptides scanning the antigen sequence or in vitro assay
based on serum using short linear or conformational peptides
scanning the antigen sequence.
[0163] In embodiments, the replication defective adenoviral vector
comprises an expression cassette comprising a coding sequence
encoding an antigen of SEQ ID NO: 3, SEQ ID NO: 12, SEQ ID NO: 15,
the RBD amino acid sequence (amino acids 57-253 of SEQ ID NO: 15
(SEQ ID NO: 446)), or an immunogenic fragment thereof. In
embodiments, the replication defective adenoviral vector comprises
an expression cassette comprising a coding sequence encoding
SARS-CoV-2 spike protein, S1 domain, S2 domain, or an immunogenic
fragment thereof. In embodiments, the expression cassette of the
immunogenic composition comprises a coding sequence for spike (S)
protein (e.g., as in preferred embodiments SEQ ID NO: 3 and SEQ ID
NO: 12), 51 domain (e.g., as in preferred embodiment SEQ ID NO: 13)
of the spike protein, or an immunogenic fragment thereof (e.g., as
in preferred embodiments SEQ ID NOS: 14-17 (FIGS. 17B-21)). In a
preferred embodiment, the coding sequence encodes the RBD sequence
comprising amino acids 57-253 of SEQ ID NO: 15 (SEQ ID NO: 446). In
certain embodiments, those encoded sequences comprise a leader
signal sequence, either native or as a recombinant sequence
comprising a pTA signal sequence (e.g., preferred embodiment
MDAMKRGLCCVLLLCGAVFVSPSGTGS (SEQ ID NO: 427)).

[0165] In certain other embodiments, the expression cassette of the

encodes at least amino acid resides 331 to 527 of SEQ ID NO: 3, SEQ
ID NO: 12, or SEQ ID NO: 13, wherein the amino acid position
numbering is based on the full-length spike protein sequence. In

acid residues may be modified via conservative substitutions based
on physico-chemical properties of the amino acids of SARS-CoV-2 at
positions 455, 486, 493, 494 and 501 of the spike protein. In this
way alternative sequences may be generated that would potentially
capture escapees (e.g., viral mutations that evade acquired
neutralizing antibodies but still bind to a host receptor) wherein
the immunogenic compositions would induce neutralizing antibodies
based on those alternative sequence(s). In embodiments, the
expression cassette of the immunogenic composition comprises a
coding sequence for the S1 domain of the spike protein, RBD of S1
domain, or an immunogenic fragment thereof, wherein the sequence

immunogenic fragment thereof, wherein the sequence comprises SEQ ID
NO: 17 wherein 455 (L) is selected from Y, F, L or S; 486 (F) is
selected from L, F, S or P; 493 (Q) is selected from L, N, Q, R or

[0167] In some embodiments, the expression cassette of the
immunogenic composition comprises a coding sequence for
modifications of a subsection of the spike protein sequence of SEQ
ID NO. 13, the amino acid sequence of that subsection being shown
in FIG. 17B ("Sequence") and below: [0168]

can be at one or more of the amino acids that serve as main contact
residues with the human ACE2 receptor, preferably amino acids 417,

[0170] Stabilized Spike Protein Antigen Design
[0171] The development of a viral vector immunogenic composition or
vaccine against Covid-19 (e.g. SARS-CoV-2) faces some key
challenges related to: (1) the ability of the viral vector to
express the protein with a quaternary structure representative of
the native pre-fusion protein expressed by the coronavirus and
compatible with the induction of neutralizing antibodies against
the SARS-CoV-2 virus; and, (2) the ability to propagate the viral
vector during its manufacture in a cell-based expression system
with limited interference that may be associated with the
concomitant expression of the transgenic spike protein.
[0172] In embodiments, designing a viral vector expressing a
stabilized spike antigen in a pre-fusion trimeric conformation
expressed on the surface of infected cells may be desirable for the
development of a Covid-19 immunogenic composition or vaccine to
address both the antigenicity and manufacturing of the vaccine. In
other embodiments, immunogenic fragments thereof (spike protein),
such as the S1 or receptor binding domain (RBD), may be desirable
for the development of a Covid-19 immunogenic composition or
vaccine, which also address both the antigenicity and manufacturing
of the immunogenic composition or vaccine. Those challenges are
due, in part, to the "fusogenic" properties of the SARS-Cov-2 spike
protein, which as used herein refers to the fusion properties of
the spike protein to gain entry in a host cell (e.g., as a coat
protein on the surface of viral particles) using ACE2 as the entry
receptor or when expressed on the host cell to fuse with neighbor
cells to form larger syncytia or syncytium (multi-nucleated host
cells) as a mean to propagate very rapidly by using this cell-cell
fusion independently of the entry receptor. Priming of coronavirus
S proteins by host cell proteases is essential for viral entry into
cells expressing ACE2 and encompasses S protein cleavage at the
S1/S2 and the S2' sites. The S1/S2 cleavage site of SARS-CoV-2 S
harbors several arginine residues (multibasic), which indicates
high cleavability (Hoffmann et al. SARS-CoV-2 Cell Entry Depends on
ACE2 and TMPRSS2 and Is Blocked by a Clinically Proven Protease
Inhibitor; Cell; 2020 Apr. 16; 181(2): 271-280.e8). Successful
conformational changes of S proteins, leading to membrane fusion,
not only require receptor binding, but also appropriate protease
activation. There is a furin site between S1 and S2 (amino acids
682-685, RRAR) subunits in SARS-CoV-2 S protein, similar to those
found in highly pathogenic influenza viruses. That furin site
(RRAR) is not present in other coronavirus S proteins (e.g., See
FIG. 1C of Walls et al. Structure, Function, and Antigenicity of
the SARS-CoV-2 Spike Glycoprotein; Cell; 2020 Mar. 9, incorporated
herein by reference), and may contribute to instability, possibly
confounding viral-vectored vaccine development. Therefore, in
certain embodiments, those amino acid residues in the SARS-Cov-2
spike protein may be removed and/or modified to ameliorate or
remove the furin enzymatic cleave site between 51 and S2 domain
present in SARS-Cov-2 spike protein.
[0173] Hence, one approach to stabilize the spike protein is to
render the protein more resistant to proteolytic degradation (1)
during expression of the protein in the cell-based manufacturing
such as in E1 complementing cell lines during production of the
(adenovirus) viral vector and/or (2) during expression of the
protein in a mammal following administration of the viral vector.
Proteolytic cleavage sites can be modified by amino-acid
substitutions, insertion or deletions in order to prevent or reduce
enzymatic degradation. Proteolytic cleavage sites of interest for
this type of approach are preferably found in solvent-accessible
regions of the protein that form the solvent-facing surface of the
three-dimensional structure of the protein trimer complex. These
solvent-accessible sites include the S1/S2 junction
QTQTNSPRRARSVASQ (SEQ ID NO: 25) and S2' junction PDPSKPSKRSF (SEQ
ID NO: 26). Other solvent accessible areas can be identified by
known methods that calculate the relative solvent accessible score
area (SASA). Potential enzymes involved in proteolytic cleavage of
spike protein include Furin, Trypsin, Elastase, Plasmin, TMPRSS2,
Chymotrypsin, Cathepsin-L, Cathepsin-B, TMPRSS11D, Dipeptidyl
Peptidase IV, MMP-13, MMP-12, MMP-2, MMP-9, MMP-3, Caspase-3,
Caspase-8, Caspase-9. Protease cleavage sites can be predicted
using known algorithms such as Proper, Properous, PeptideCutter,
Pripper, CasCleave, CasCleave 2.0, CASVM and iProt-Sub.
[0174] Cleavage of the S1/S2 junction QTQTNSPRRARSVASQ (SEQ ID NO:
25) from SARS-CoV-2 and/or corresponding sequences in other
coronaviruses, has been demonstrated to be primarily dependent upon
arginine residues such as arginine at positions 685, 682 and/or 683
from SEQ ID NO: 3 and SEQ ID NO: 12. To interfere with proteolytic
cleavage, hydrophilic, non-positively charged amino-acids or small
amino-acids such as N, Q, D, E, T, S, G or A can be considered for
substitution of arginine residues. In addition, the S1/S2 junction
can be rendered resistant to proteolytic cleavage by deletion or
insertion of amino acids, provided that those sequence
modifications do not alter the three-dimensional conformation of
the spike antigen so to preserve its antigenicity and ability to
stimulate the production of neutralizing antibodies. A similar
approach can also be applied to the S2' junction PDPSKPSKRSF (SEQ
ID NO: 26) for the Lysine residue at position 814 and Arginine
residue at position 815 in sequence SEQ ID NO: 3 and SEQ ID NO: 12.
In embodiments, the expression cassette of the immunogenic
composition comprises a coding sequence of SEQ ID NO: 18 (a
preferred embodiment); SEQ ID NO: 19 (a preferred embodiment); or
SEQ ID NO: 20. See FIGS. 22 to 24. Thus, in certain preferred
embodiments, the encoded sequence of the immunogenic composition is
a sequence, or immunogenic fragment thereof, presented in SEQ ID
NO: 18 or SEQ ID NO: 19, or a sequence having at least 80% homology
and/or identity to SEQ ID NO: 18 or SEQ ID NO: 19. In certain
embodiments, the encoded sequence of the immunogenic composition is
a sequence with at least about 80%, 81%, 82%, 83%, 84%, 85%, 86%,
87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99%,
homology and/or identity to SEQ ID NO: 18 or SEQ ID NO: 19.
[0175] In other embodiments, another approach for stabilizing the
spike protein includes maintaining the metastable spike protein in
its prefusion conformation. Modifications of the sequence to
stabilize coronavirus spike protein in a prefusion conformation
have been previously disclosed in Pallesen et al. 2017
(Immunogenicity and structures of a rationally designed prefusion
MERS-CoV spike antigen. Proc Natl Acad Sci USA. 2017 Aug. 29;
114(35):E7348-E7357) and Wrapp et al. 2020 (Cryo-EM structure of
the 2019-nCoV spike in the prefusion conformation. Science. 2020
Mar. 13; 367(6483): 1260-1263), showing that proline substitutions
in the loop between the first heptad repeat (HR1) and the central
helix (CH) restrict premature triggering of the fusion protein and
often increase expression yields of prefusion ectodomains. See
FIGS. 22 to 24 and SEQ ID NOS: 18, 19 and 20.
[0176] In embodiments, other approaches consist of facilitating the
expression of the protein at the surface of infected cells. The
spike protein may be retained in endoplasmic reticulum and/or the
pre-golgi/golgi, a phenomenon associated with the nature of the
transmembrane and/or intracellular domain. Preventing intracellular
retention can be achieved by modifying the intracellular domain
(IC) by substitution of cysteine in cysteine-rich domains or
through the modification of the C-terminal endoplasmic reticulum
retention motif (VKLHYT (SEQ ID NO: 409)). See FIG. 24 and SEQ ID
NO: 20.
[0177] In certain embodiments, limiting the toxicity of the
transgenic spike protein during manufacturing of the viral vector
can be achieved by modifying the fusion peptide contained within
the spike antigen sequence. Modification by deletion, insertion of
amino-acids and/or substitution of amino-acids can be introduced in
the spike sequence to disrupt the alpha-helix conformation of the
fusion peptide. Disruption of the alpha helix conformation of the
fusion peptide can be achieve by the substitution of specific amino
acids by proline residues.
[0178] Accordingly, in embodiments the design of a viral vector
immunogenic composition or vaccine against Covid-19 expressing a
stabilized full-length trimeric spike antigen may comprise one or
more of the modifications described above. Example of those
modifications are presented in Table 1 (S1/S2, S2' and fusion
domains) and Table 2 (HR1/CH and IC domains) (FIGS. 22-24, SEQ ID
NOS: 18-20).

[0179] In embodiments, the present immunogenic composition is a
multivalent composition. In certain embodiments, the expression
cassette of the replication defective adenoviral vector further
comprises a coding sequence encoding one or more of SARS-CoV-2
structural proteins envelope (E), membrane (M) or nucleocapsid (N).
Each of those structural proteins is presented herein as SEQ ID NO:
5; SEQ ID NO: 6 and SEQ ID NO: 10, respectively. See also FIGS. 5,
6 and 10. In alternative embodiments, those structural proteins may
be encoded from a separate replication defective adenoviral vector
and provided as a multivalent formulation with a replication
defective adenoviral vector comprising an expression cassette
comprising a coding sequence encoding at least SARS-CoV-2 (2019
novel coronavirus; 2019-nCoV) spike (S) protein receptor binding
domain (RBD), or at least one immunogenic fragment thereof
[0180] Neutralizing the Post-Fusion Spike Antigen
[0181] As discussed above, unlike other beta-coronaviruses of
subgroup B, the S protein of SARS-CoV-2 harbors a unique S1/S2
furin-recognizable site, indicating that its S protein may possess
unique infectious properties. Indeed, in active SARS-CoV-2
infection, syncytium phenomenon were shown to be naturally formed
by infected cells, which is rarely reported in SARS-CoV infection,
demonstrating a high capacity to mediate membrane fusion (Xu Z. et
al. Pathological findings of COVID-19 associated with acute
respiratory distress syndrome. Lancet Respir Med. 2020 April;
8(4):420-422.). These cytopathic syncytia are presumably
responsible for, at least in part, the pathology observed in
COVID-19 patients. Also, the formation of syncytia helps the virus
to propagate very rapidly by using this cell-cell fusion mechanism
independently of the receptor (receptor independent spread).
Therefore, induction of neutralizing antibody against the S antigen
in its post-fusion form represents a means for limiting the
formation of syncytia and/or preventing the rapid spread of the
virus in an entry receptor-independent manner. The post-fusion
spike antigen is achieved after cleavage of spike protein by
proteases. Cleavage induces a tridimensional rearrangement of the
S2 domain as presented in Wall et al. 2017 (Walls, et al. Tectonic
conformational changes of a coronavirus spike glycoprotein promote
membrane fusion. Proc Natl Acad Sci USA. 2017;
114(42):11157-11162.).
[0182] In some embodiments, SARS-CoV-2 immunization vector can also
or alternatively comprise a polynucleotide causing expression in a
cell of spike antigen without the S1 domain such as the S2 domain
of spike (approximately from amino-acid residue 686 of SEQ ID NO:
3) or the S2' domain of spike (approximately from amino-acid
residue 816 of SEQ ID NO: 3) or a sequence starting beyond residue
816 of SEQ ID NO: 3 and at minimum comprising the HR1, HR2 and a
transmembrane domain. In some preferred embodiments, these
SARS-CoV-2 immunization vectors induce an immune response that
neutralizes the post-fusion spike protein (e.g. antibodies against
the S2 domain) and provide protection by preventing the formation
of syncytia and/or by preventing the propagation of the virus in an
entry-receptor independent manner. In some embodiments, the
expression cassette of the immunogenic composition comprises a
coding sequence for the S2 portion of the spike (S) protein (e.g.,
SEQ ID NO: 21, SEQ ID NO: 22, SEQ ID NO: 23). In some embodiments,
the expression cassette of the immunogenic composition comprises a
coding sequence for the S2 portion of the spike (S) protein
containing an additional transmembrane domain to replace the fusion
peptide (e.g., SEQ ID NO: 24). The polypeptides of SEQ ID NOS: 21,
22, 23, and 24 are shown below:

[0183] T Cell Epitope Peptides
[0184] In embodiments, the SARS-CoV-2 immunization vectors comprise
one or more peptide-encoding sequences from .kappa. to 60 amino
acids in length (and concatenated if more than one), wherein each
peptide comprise at least one CD8+ T cell epitope and/or at least
one CD4+ T cell epitope. In this case, the concatenated
peptide-encoding polynucleotide express a polypeptide where T cell
epitopes or T-cell epitope-containing sequences are separated by a
spacer sequence containing amino-acids such as glycine, serine or
alanine residues. The polynucleotide may further comprise
polynucleotide sequences coding for ubiquitin or a signal peptide.
In some embodiments, the SARS-CoV-2 immunization vectors comprise
one or more polynucleotides encoding one or more S protein
antigens. (Ahmed, et al. Preliminary Identification of Potential
Vaccine Targets for the COVID-19 Coronavirus (SARS-CoV-2) Based on
SARS-CoV Immunological Studies. Viruses, 12: 254 (2020)). The one
or more S protein peptide antigens can comprise any T cell epitope,
for instance, any of the peptides shown in Table 3A:

combinations of the same. In some preferred embodiments, the
vectors can encode multiple of such epitopes, separately or as part
of a single polypeptide (e.g., in some embodiments concatenated,
optionally separated by a linker amino acid sequence of two to ten
amino acids).
[0188] In some embodiments, SARS-CoV-2 peptide sequences encoded by
the SARS-CoV-2 immunization vectors can be selected based on the
ability to stimulate CD4.sup.+ and CD8.sup.+ T cell responses, and
can in some embodiments be selected based on the prediction of
proteome regions containing the highest number of HLA class I and
HLA class II binding motifs across a range of selected HLA alleles.
In some embodiments, analysis of HLA class II binding motifs across
the SARS-CoV-2 sequences can be performed using NetMHCpan EL 4.0
available at IEDB (http://tools.iedb.org/mhci/; Jurtz, et al.
NetMHCpan-4.0: Improved Peptide-MHC Class I Interaction Predictions
Integrating Eluted Ligand and Peptide Binding Affinity Data. J
Immunol. 2017; 199(9):3360-3368). In some embodiments, the
NetMHCpan EL 4.0 can be used to identify binding motifs having a
length varying from 9 to 11 amino acids to HLA class I molecules
and assigned a percentage rank (% Rank). In some embodiments, high
affinity binding peptides can be identified as those exhibiting a
%-Rank .ltoreq.0.1 while moderate affinity binding peptides can be
considered to have a %-rank comprised between >0.1 and
.ltoreq.0.5. In preferred embodiments, the NetMHCpan EL 4.0
prediction can be performed with a set of 18 HLA-A alleles, 32
HLA-B alleles and 20 HLA-C alleles shown here: HLA-A*01:01,
HLA-A*02:01, HLA-A*02:06, HLA-A*03:01, HLA-A*11:01, HLA-A*23:0,

HLA-C*14:02, HLA-C*15:02, HLA-C*16:01 and HLA-C*17:01. Other HLA
class I alleles may also be suitable as would be understood by
those of ordinary skill in the art.
[0189] In some embodiments, HLA class II binding motifs within the
SARS-CoV-2 polypeptide sequences can be performed using NetMHCII
2.3 (http://www.cbs.dtu.dk/services/NetMHCII/; Jensen et al.
Improved methods for predicting peptide binding affinity to MHC
class II molecules. Immunology. 2018 July; 154(3):394-406.) which
is based on ensembles of artificial neural networks trained on
quantitative peptide binding affinity data from the Immune Epitope
Database (IEDB). In some embodiments, NetMHCII 2.3 can be used to
identify peptides that can presented by HLA class II molecules by
determining, e.g., the percentage rank (%-Rank) (related to the
affinity of the peptides for the HLA molecules) and the core nine
amino acid binding motif. In some embodiments, high affinity HLA
class II binding peptides can be identified as those exhibiting a
%-Rank .ltoreq.2 while moderate affinity binding peptides can be
considered to have a %-Rank >2 and 10. In preferred embodiments,
the NetMHCII 2.3 system can be based on a set of 20 HLA-DR alleles,
20 HLA-DQ alleles and 9 HLA-DP alleles shown here:

[0190] The number of HLA class I binding motifs across the selected
70 HLA class I alleles and the number of HLA class II binding
motifs across the selected 49 HLA class II alleles having a high or
high plus (+) moderate affinity were respectively calculated for
each 41 amino-acid long window scanning the SARS-CoV-2 sequences
and presented in FIGS. 27-70. For this analysis, predicted
transmembrane domains were deselected due to their high
hydrophobicity. Based on this analysis, forty-two (42) long peptide
sequences with a length varying from 34 to 124 amino-acids as
presented in Table 4 were selected based on the highest content in
HLA class I and/or HLA class II motifs across the SRAS-CoV-2
proteome (SEQ ID NO. 410).

[0194] For each selected sequence from SEQ ID NO: 328 to SEQ ID NO:
369, a map of HLA class I and HLA class II binding motif are
presented in FIGS. 29-70. In FIGS. 29-70, the N-terminal amino acid
(i.e., amino acid #1) for each HLA class I and II motif therein is
identified by an X or an O, wherein X further indicates a high
affinity motif and O indicates moderate affinity for the HLA
binding motif. Exemplary HLA binding motifs can be deduced from
FIGS. 29 to 70 by including the X or O amino acid residue and
including the subsequent eight to ten amino acids in the motif such
that each motif includes nine to eleven amino acid residues (i.e.,
each motif is a 9-11 amino acid peptide), with reference to the SEQ
ID number indicated in each figure. Any such binding motifs can be
used as immunogens, alone and/or in combination, in the vectors
disclosed herein. Other binding motifs of any of SEQ ID NOS.
328-369 may also be suitable for inclusion in the SARS-CoV-2
immunization vectors herein as would be understood by those of
ordinary skill in the art.
[0195] RBD Sequences Matching Circulating SARS-CoV-2 Variants
[0196] As described above, rdAd vectors may be designed to encode
sequences homologous to SEQ ID NO: 13, SEQ ID NO: 14, SEQ ID NO: 15
or any sequences comprising SEQ ID NO: 446 with or without
additional flanking residues and incorporating single or multiple
RBD mutation(s) as those described in FIG. 17B. Preferably, the RBD
variant sequences may include single or combined mutations at amino
acid positions 367, 403, 439, 417, 446, 447, 449, 452, 453, 455,
456, 470, 473, 475, 476, 477, 478, 484, 486, 487, 490, 493, 494,
496, 499, 500, 501, 502, 503, 504, and/or 505, wherein the amino
acid position numbering corresponds to SEQ ID NO: 3 (full length
spike protein) (FIG. 17B). More preferably, the RBD sequences
include single or combined mutations at position K417T, K417N,
E484K, L452R and/or N501Y (FIG. 17B). In preferred embodiments, the
RBD variant protein sequences can be selected from the group
consisting of SEQ ID NOS: 412-417 wherein the RBD sequence is
underlined:

[0198] Variant RBD Sequences and Multivalent Vaccine
Compositions
[0199] It may be also advantageous to develop multivalent
immunogenic compositions or vaccines providing immunity against
co-circulating SARS-CoV-2 variants and potentially future variants.
In some embodiments, multivalent genetic immunogenic compositions
or vaccine compositions can be achieved by combining several
monovalent genetic immunogenic compositions or vaccine
compositions, each expressing an antigen sequence variant in the
same preparation. In some embodiments, a single genetic construct
can also be constructed to co-express multiple antigen sequence
variants to provide a multivalent RBD SARS-CoV-2 immunogenic
compositions or vaccine composition. In some embodiments, for
instance, an rdAd vector of this disclosure can comprise one or
more expression cassettes comprising a SARS-CoV-2 antigen coding
sequence that incorporates one or more mutations in the spike
protein RBD region, and that would be able to protect against
circulating SARS-CoV-2 variants and potentially future variants. In
some embodiments, a single genetic construct may comprise multiple
RBD variant units arranged co-linearly within a single expression
cassette. RBD variant units may be selected from SEQ ID NO: 13, SEQ
ID NO: 14, SEQ ID NO: 15 or any sequences comprising SEQ ID NO: 446
with or without additional flanking residues and incorporating
single or multiple RBD mutation(s) as those described in FIG. 17B.
Each RBD variant unit can be spaced from other RBD variant in the
co-linear arrangement by a flexible spacer sequence comprising, for
instance, glycine and serine amino acid residues. In preferred
embodiments, the spacer peptide can comprise the amino acid
sequence (GGGGS)n, (GGGGA)n, (GGGGQ)n, (GGGPS)n, (GPGPG)n and
combinations thereof, where n is comprised between 1 and 10. Other
spacers, preferably hydrophilic in nature and comprising polar
amino acids may also be suitable as would be understood by those
ordinary skill in the art. In some embodiments, spacers can include
one or more proteolytic cleavage motifs for proprotein convertases
(PCs), also known as eukaryotic subtilases, represented by a group
of serine proteases comprising furin (PACE), PC1 (PC3), PC2, PC4,
PACE4, PC5 (PC6), and PC7 (LPC, PC8) that generate bioactive
proteins and peptides, such as hormones, receptors, and growth
factors by cleaving precursor proteins at multi-basic motifs. In
preferred embodiments, such multi-basic motifs include the one
described in table below:

position
[0200] Spacer sequences are preferably optimized to avoid the
introduction of neo-epitopes within the pseudo-protein sequence.
Moreover, different spacers can be combined in the same sequence.
In some embodiments, the spacers may include a flexible portion and
a cleavable portion. In some embodiments, different spacer
sequences may be used between RBD variant units within the same
multivalent construct. In a preferred multivalent RBD vector, the
number of RBD variant units arranged colinearly in the same genetic
sequence may vary from 2 to 10 units, preferably 2 to 6 units. The
respective order of the RBD variant sequence may also vary; the use
of spacer being introduced so that each RBD variant unit are
immunogenically-independent. Each RBD variant unit can include any
single mutation or combination of mutations, as those described in
FIG. 17B.
[0201] Preferably, the RBD variant sequences may include single or
combined mutations at positions 367, 403, 439, 417, 446, 447, 449,
452, 453, 455, 456, 470, 473, 475, 476, 477, 478, 484, 486, 487,
490, 493, 494, 496, 499, 500, 501, 502, 503, 504, and/or 505 (FIG.
17B). More preferably, the RBD sequences include single or combined
mutations at position K417T, K417N, E484K, L452R and/or N501Y,
wherein the amino acid position numbering corresponds to SEQ ID NO:
3 (full length spike protein) (FIG. 17B). SEQ ID NOS: 438 to 443
and 460 are provided as preferred embodiments of RBD variant
sequence that can be used for the design of the multivalent RBD
vector. Preferred examples of multivalent RBD sequences comprising
multiple RBD variant units are presented as SEQ ID NO: 444, SEQ ID
NO: 445, SEQ ID NO: 475 and SEQ ID NO: 476. In preferred
embodiments, the multivalent RBD sequences to be expressed by the
rdAd (a "multivalent RBD vector", a type of multivalent
hAd5-SARS-CoV-2) will be preceded by a leader/signal peptide
sequence to address the expression of the polypeptide the cellular
secretory pathway. Commonly used leader peptide sequences for
efficient targeting of a recombinant protein expressed in mammalian
cells are described in Table 9.
[0202] In preferred embodiments, the RBD variant protein sequences
can be selected from the group consisting of SEQ ID NOS: 438-443
and 460, and exemplary multivalent RBD constructs are shown in SEQ
ID NOS: 444, 445, 475 and 476 below, wherein the RBD sequence is

[0203] Other peptides, polypeptides, constructs, and combinations

those of ordinary skill in the art.
[0204] Receptor Binding Antagonists
[0205] In some embodiments, the SARS-CoV-2 immunization vectors
(i.e., those expressing one or more exogenous antigens) can
comprise polynucleotides encoding one or SARS-CoV-2 blocking
proteins (e.g., receptor binding antagonists). For instance,
coronaviruses such as SARS-CoV-2 are known to use homotrimers of
the spike (S) protein for host cell attachment, fusion and entry
into the host cell, and can involve sialic acids and/or ACE2 (a
cell membrane C-terminal anchored protein that catalyzes the
cleavage of angiotensin 1 into angiotensin 1-9, and of angiotensin
II into the vasodilator angiotensin 1-7, thus playing a key role in
systemic blood pressure regulation (Alifano, et al.
Renin-angiotensin system at the heart of COVID-19 pandemic.
Biochimie, 174: 30-33 (2020)). Host cell proteases are known to
process coronavirus S protein to generate two subunits (S1 and S2),
which remain non-covalently bound in the pre-fusion conformation of
the virus (see, e.g., Tortorici, et al. Structural basis for human
coronavirus attachment to sialic acid receptors. Nat. Struc. Mol.
Biol. 26: 481-489 (2019)). The S1 subunit comprises four domains
NTD, RBD, SD1 and SD1 with NTD and RBD separated by a linker
sequence as presented in FIG. 13. In some embodiments, SARS-CoV-2
immunization vector can also or alternatively comprise a
polynucleotide causing expression in a cell of at least one or both
of the S1 domains (NTD and/or RBD) or as part of the full-length S
protein (with or without transmembrane domain), and/or an
immunogenic fragment of the same that, in some preferred
embodiments, induces an immune response that interferes with the
binding of the S protein (e.g., an antibody against the S1 RDB
and/or NTD domain(s)) to the above-mentioned sialic acids and/or
ACE2, thereby interfering with entry of SARS-CoV-2 into a host cell
and/or its effect on ACE2. In some embodiments, the SARS-CoV-2
immunization vector can also or alternatively comprise a
polynucleotide causing expression in a cell of a protein (e.g., an
antibody or fragment thereof, or a peptide (e.g., an ACE2 mimic,
RBD binding peptide)) that can bind to S protein (e.g., the S1 RDB
and/or NTD domain(s) thereof, and/or S2), thereby interfering with
entry of SARS-CoV-2 into a host cell (e.g., blocking the binding of
the S protein to its host cells receptors such as ACE2) and/or its
effect on ACE2 (collectively referred to as "RBD binding agents").
In some embodiments, the RBD binding agent can be a peptide with at
least one domain corresponding to a virus-binding domain of ACE2,
e.g., a peptide the conformationally matches the RBD. In some
embodiments, the SARS-CoV-2 immunization vector can also or
alternatively comprise a polynucleotide causing expression in a
cell of a protein that can bind to ACE2 (e.g., an ACE2 binding
agent) and/or otherwise prevent attachment of the S protein (e.g.,
the S1 RDB and/or NTD domain(s) thereof, and/or S2, can be
expressed as free proteins) thereto, thereby interfering with entry
of SARS-CoV-2 into a host cell and/or its effect on ACE2,
preferably without interfering with the normal physiological
function of ACE2 (i.e., other than its ability to serve as a
receptor for SARS-CoV-2). In some embodiments, such an ACE2 binding
agent can be a peptide, such as a peptide that interferes with the
binding of SARS-CoV-2 to ACE2. In some embodiments, the SARS-CoV-2
immunization vector can comprise one or more polynucleotides
encoding both a RBD binding agent and an ACE2 binding agent, and/or
a dual RBD binding and ACE2 binding agent. In preferred
embodiments, the RBD binding agent(s) and/or ACE2 binding agent(s)
interfere with the interaction of ACE2 and RBD at one or more of
the 15 residues from ACE2 (24(Q), 27(T), 30(D), 31(K), 34(H),
35(E), 37(E), 38(D), 41(Y), and 42(Q) are in al, one residue
(residue 82 M) comes from .alpha.2, residues 353(K), 354(G),
355(D), and 357(R) come from the linker between (33 and (34) that
are currently understood to interact with RBD (Han, et al.
Computational Design of ACE2-Based Peptide Inhibitors of
SARS-CoV-2. ACS Nano 2020, Publication Date: Apr. 14, 2020
(https://doi.org/10.1021/acsnano.0c02857); Yan, et al. Structural
Basis for the Recognition of the SARS-CoV-2 by Full-Length Human
ACE2. Science 367: 1444-1448 (2020)); preferably without affecting
the normal physiological function (i.e., other than its ability to
serve as a receptor for SARS-CoV-2) of the ACE2 protein. Thus, in
some embodiments, the SARS-CoV-2 immunization vectors of this
disclosure can comprise one or more polynucleotides that encode
secreted antigens (e.g., S1, NTD, RBD, ACE2 binding agent) that can
bind to and block the ACE2 receptor adding additional activity in
addition to immunity.

[0207] In some embodiments, the SARS-CoV-2 immunization vector(s)
can also or alternatively comprise at least one polynucleotide
encoding a polypeptide and/or peptide that improves or enhances the
immunogenicity of the vector(s) (e.g., acts as an adjuvant (e.g., a
molecular adjuvant)) that is expressed by a host cells and assists
in the induction of an anti-SARS-CoV-2 immune response, and/or
enhances an ongoing anti-SARS-CoV-2 immune response, resulting from
administration of the vector(s) to a host (e.g., in preferred
embodiments without inducing a systemic inflammatory response that
could interfere with the recovery of a patient from SARS-CoV-2
infection). For instance, in some embodiments, the SARS-CoV-2
immunization vector(s) can encode one or more: 1) polypeptides or
peptides that function as "co-stimulatory" component(s) such as,
for instance, polypeptides or peptides that bind members of the
CD28 family (i.e., CD28, ICOS; Hutloff, et al. Nature 1999, 397:

molecular adjuvants are also contemplated herein as would be
understood by those of ordinary skill in the art.
[0208] Formulations
[0209] In some embodiments, the present replication deficient
adenovirus vector that contains and expresses SARS-CoV-2 spike (S)
antigen, or immunogenic fragment thereof, that can be
codon-optimized for the human subject, may be combined with other
coronavirus antigens (e.g. viral vector expressed antigens) to form
a multivalent coronavirus pharmaceutical formulation. The other
components may be included to induce a humoral response with
antibodies to a different epitope than that presented in the
instant adenoviral vector containing spike protein antigen. In
other embodiments, the other component(s) may be included to induce
a different arm of the immune system, such as cell-mediated or
mucosal immune response to a coronavirus antigen.
[0210] In certain embodiments provided herein is a monovalent or
multivalent coronavirus pharmaceutical formulation suitable for
intranasal administration to a human subject, comprising: an
effective amount of at least 10.sup.7 viral particles (vp) or
infectious units (ifu) (e.g., at least 1.times.10.sup.7, or at
least 1.times.10.sup.8, or at least 1.times.10.sup.9, or at least
1.times.10.sup.10, or at least 1.times.10.sup.11 vp or ifu) of rdAd
vector (i.e., one or more SARS-CoV-2 vectors); and, a
pharmaceutically acceptable excipient, diluent, and/or carrier. In
some embodiments, the rdAd vector contains and expresses SARS-CoV-2
spike antigen, or an immunogenic fragment thereof codon optimized
for the human subject; and, a pharmaceutically acceptable
excipient, diluent, and/or carrier. In certain embodiments, the
effective amount induces a protective immune response configured to
provide seroprotection, mucosal protection or cellular protection
(e.g., based on a cellular immune response such as T cells) to the
human subject for at least 1 month (e.g., 28 days or 4 weeks), at
least 2 months, at least 3 months, at least 6 months, at least 8
months, at least 12 months, at least 13 months, or at least 14
months against SARS-CoV-2 infection. The period of at least one
month to at least 14 months can be considered a duration of
protection. In certain embodiments, the protective immune response
comprises a combined mucosal, humoral and/or T cell response. In
embodiments, the protective immune response is induced via a single
intranasal dose. In alternative embodiments, the protective immune
response is induced via two or more intranasal doses, for example a
prime dose followed by a boost dose about 2 to 3 weeks later.
[0211] In exemplary embodiments provided herein is a SARS-CoV-2
immunogenic composition (e.g., vaccine) pharmaceutical formulation
suitable for intranasal administration to a human subject,
comprising: an effective amount of at least 10.sup.7 viral
particles (vp) or infectious units (ifu) (e.g., at least
1.times.10.sup.7, or at least 1.times.10.sup.8, or at least
1.times.10.sup.9, or at least 1.times.10.sup.10, or at least
1.times.10.sup.11 vp or ifu) of a replication defective adenoviral
vector comprising an expression cassette comprising a coding
sequence encoding at least SARS-CoV-2 spike (S) protein receptor
binding domain (RBD), or at least one immunogenic fragment thereof
codon optimized for a human subject, wherein the composition is
configured to induce neutralizing antibody to the spike protein
RBD, in the human subject; and, a pharmaceutically acceptable
diluent or carrier.
[0212] With respect to dosages, routes of administration,
formulations, adjuvants, and uses for recombinant viruses and
expression products therefrom, compositions of the invention may be
used for parenteral, topical, or mucosal administration, preferably
by intradermal, subcutaneous, intranasal or intramuscular routes.
When mucosal administration is used, it is possible to use oral,
ocular or nasal routes. In exemplary embodiments, the present
immunogenic compositions (e.g., vaccine) are administered
intranasally. In exemplary embodiments, the present immunogenic
compositions (e.g., vaccine) are administered intranasally to the
mammalian subject. In some embodiments, the SARS-CoV-2 immunogenic
composition can be administered using a device such as a
microneedle (e.g., as in Kim et al. EBioMedicine, 00 (2020)).
[0213] The immunogenic compositions (e.g., formulations) which
comprise the adenovirus vector of interest, can be prepared in
accordance with standard techniques well known to those skilled in
the pharmaceutical or veterinary art. See Example 1 and 2. Such
formulations can be administered in dosages and by techniques well
known to those skilled in the clinical arts taking into
consideration such factors as the age, sex, weight, and the route
of administration. The formulations can be administered alone
(i.e., as the sole active agent(s)) or can be co-administered or
sequentially administered with compositions, e.g., with "other"
immunogenic compositions, or attenuated, inactivated, recombinant
immunogenic compositions (e.g., vaccine) or therapeutic
compositions thereby providing multivalent or "cocktail" or
combination compositions of the invention and methods employing
them. In some embodiments, the formulations may comprise sucrose as
a cryoprotectant and polysorbate-80 as a non-ionic surfactant. In
certain embodiments, the formulations further comprise free-radical
oxidation inhibitors ethanol and histidine, the metal-ion chelator
ethylenediaminetetraacetic acid (EDTA), or other agents with
comparable activity (e.g., block or prevent metal-ion catalyzed
free-radical oxidation).
[0214] The compositions (e.g., formulations) may be present in a
liquid preparation for mucosal administration, e.g., oral, nasal,
ocular, etc., formulations such as suspensions and, preparations
for parenteral, subcutaneous, intradermal, intramuscular,
intravenous (e.g., injectable administration) such as sterile
suspensions or emulsions. In such formulations the adenoviral
vector may be in admixture with a suitable carrier, diluent, or
excipient such as sterile water, physiological saline, viscosity
enhancing excipients or the like. Certain specialized formulations
for mucosal administration can be used, including mucoadhesives,
mucosal penetrants and mucosal disruptants. The formulations can
also be lyophilized or frozen. The formulations can contain
auxiliary substances such as wetting or emulsifying agents, pH
buffering agents, adjuvants, preservatives, and the like, depending
upon the route of administration and the preparation desired. The
formulations can contain at least one adjuvant compound. In
exemplary embodiments, the present immunogenic compositions (e.g.,
vaccines) are non-adjuvanted. Standard texts, such as "REMINGTON'S
PHARMACEUTICAL SCIENCE", 17th edition, 1985, incorporated herein by
reference, may be consulted to prepare suitable preparations,
without undue experimentation.
[0215] In some embodiments, an effective amount (e.g., an amount
that induces a protective immune response) of the adenoviral vector
is at least 10.sup.7 viral particle (vp) or infectious units (ifu)
(e.g., at least 1.times.10.sup.7, or at least 1.times.10.sup.8, or
at least 1.times.10.sup.9, or at least 1.times.10.sup.10, or at
least 1.times.10.sup.11 vp or ifu) of a replication deficient
adenoviral vector containing and expressing coronavirus spike
protein antigen, or fragment thereof, codon optimized for the human
subject. As understood by one of skill in the art, codon
optimization improves expression of heterologous genes in a host
organism.
[0216] In preferred embodiments, an "effective amount" of
adenoviral vector and/or immunogenic composition is one
administered to a host in a form, dose, and/or administration
regimen sufficient to induce an anti-SARS-CoV-2 immune response
(e.g., humoral, mucosal and/or cell-mediated immune response) that
in some embodiments can be protective from SARS-CoV-2 infection
(and/or CoV disease progression). In some embodiments, such as
described in the examples herein, a host to which the effective
amount was administered can exhibit an induction of (e.g., the
appearance of) and/or an increase in the number and/or function of
anti-SARS-CoV-2 antibody-producing cells (e.g., B cells, plasma
cells) that produce antibodies that bind to CoV and/or antigens (or
immunogens) thereof, such as an SARS-CoV-2 specific immunoglobulin
G (IgG) response. In some embodiments, such as described in the
examples herein, a host to which the effective amount was
administered can exhibit an induction of (e.g., the appearance of)
and/or an increase in the number and/or function of cells forming
an anti-SARS-CoV-2 cell-mediated response (e.g., T cells,
granulocytes, natural killer (NK) cells, and the like). In some
embodiments, a host to which the effective amount was administered
can exhibit an induction of (e.g., the appearance of) and/or an
increase in the number and/or function of anti-SARS-CoV-2
antibody-producing cells and cells forming an anti-SARS-CoV-2
cell-mediated response.
[0217] In order to determine whether a host to which the effective
amount was administered exhibits exhibit an induction of (e.g., the
appearance of) and/or an increase in the number and/or function of
anti-SARS-CoV-2 antibody-producing cells, in some embodiments, a
SARS-CoV-2-specific enzyme-linked immunosorbent assay (ELISA) can
be used. As shown in the examples using a murine model, following
administration of an immunogenic composition (e.g., 21 days after
administration), mice can bled to provide samples for determining
the presence of a systemic antibody response using a
SARS-CoV-2-specific ELISA (e.g., to determine SARS-CoV-2 specific
IgG response has occurred). Briefly, ELISA can be performed by
coating polystyrene 96-well plates overnight at 4.degree. C. with 1
.mu.g/ml of SARS-CoV-2 S protein in sodium carbonate buffer (pH
9.3). Plates can be washed (e.g., three times in PBS with 0.02%
Tween 20) and blocked (e.g., with non-fat dried milk) for a
suitable amount of time and temperature (e.g., one hour at
37.degree. C. with PBS, 2% BSA, and 0.02% Tween 20). Serum from
hAd5-SARS-CoV-2 vaccinated mice can be serially diluted (e.g., in
PBS) and incubated at an appropriate temperature and time (e.g.,
37.degree. C.), washed (e.g., four times with PBS with 0.02% Tween
20) and then incubated with a labeled secondary antibody (e.g.,
biotin-labeled goat anti-mouse secondary antibody) for an
appropriate amount of time (e.g., one hour). The samples can then
be washed and incubated with an appropriate reagent (e.g.,
HRP-conjugated streptavidin), and developed using an appropriate
agent (e.g., tetramethylbenzidine substrate), the reaction being
stopped with the addition of an appropriate reagent (e.g., 2 N
H.sub.2SO.sub.4), and emission (450 nm) read using an microplate
reader. In some embodiments, administration to a host of an
effective amount of an immunogenic composition comprising an
adenoviral vector encoding one or more CoV antigens (e.g. Spike
protein) can result in the expression of SARS-CoV-2-specific (e.g.,
CoV S protein-specific) antibodies of a particular type (e.g., IgA,
IgM, IgG) and/or amount (e.g., a particular reciprocal mean
endpoint indicative of a response (e.g., as compared to naive
hosts). Other assay systems can also be used to determine whether
an effective amount has been administered such as, for instance but
without limitation, neutralizing antibody assays.
[0218] In order to determine whether a host to which the effective
amount was administered exhibits exhibit an induction of (e.g., the
appearance of) and/or an increase in the number and/or function of
cells forming an anti-SARS-CoV-2 cell-mediated response, cell types
and/or numbers and/or cytokine expression and/or functional assays
can be used. For instance, in some embodiments, T cells of a host
to which (or whom) an immunogenic composition was administered can
be isolated and studied (e.g., physically isolated from other cells
and/or as present within a biological sample such as blood). In
some embodiments, an intracellular cytokine staining assay can be
performed to determine the type and/or number of cells expressing a
particular cytokine, and/or the level of such cytokine being
expressed therein. Briefly, a biological sample (e.g., blood,
spleen) of a host to which an immunogenic composition has been
administered can be isolated at a particular point following
administration (e.g., eight to 21 days post-administration). Cells
(e.g., approximately 10.sup.6 cells in cell culture media (e.g.,
RPMI with 10% FBS and HEPES)) isolated from said biological
sample(s) can then be plated in a culture plate(s) (e.g., round
bottom 96 well plate), stimulated for an appropriate amount of
time, temperature, etc. (e.g., 6 hours at 37.degree. C., 5%
CO.sub.2) in the presence of stimulator(s) (e.g., 10 .mu.g/ml
brefeldin A and either .alpha.-CD3 (2C11 clone) or 10 .mu.g of CoV
peptide (e.g., the spike antigen SARS-CoV-2 peptide (SEQ ID NO 3)
in 90% DMSO). Following CoV peptide stimulation, cells can be
washed (e.g., once with phosphate-buffered saline (PBS)) and
stained for the following cell surface markers indicating cell type
(e.g., .alpha.-CD8-PerCP-Cy 5.5 (clone 53-6.7), .alpha.-CD3-AF700
(clone 500A2), and .alpha.-CD19-BV605 (clone 1D3)). Cells can then
be fixed (e.g., using formalin), permeabilized, stained for
intracellular cytokine markers (e.g., .alpha.-IFN-.gamma.-APC
(clone B27)), and analyzed by flow cytometry (e.g., using an
Attune-NXT). In some embodiments, an effective amount can be an
amount of immunogenic composition that raises the number of cells
expressing the cytokine (e.g., IFN-.gamma.) and/or the amount
expressed by such cells.
[0219] In some embodiments, the anti-SARS-CoV-2 immune response is
protective, meaning that it can protect a host from experiencing
one or more of the symptoms of SARS-CoV-2 infection. In some
embodiments, a protective immune response prevents SARS-CoV-2
infection, which can be demonstrated by challenge of a host to
which (or whom) the effective amount was administered. In some
embodiments, an immunogenic composition, and/or effective amount
thereof, that is protective is a vaccine. To determine if an
immunogenic composition is protective, a pre-clinical animal model
can be used. For instance, in some embodiments, a SARS-CoV-2
immunogenic composition can be administered to mice susceptible to
infection and disease and the mice can be challenged by live
SARS-CoV-2 at a subsequent time (e.g., 7-21 days following
administration) and monitored for survival and/or symptoms in
comparison to the control group. Symptoms of SARS-CoV-2 infection
can also be monitored, including clinical signs of disease (e.g.,
upper and lower respiratory symptoms). Thus, in some embodiments,
in order to determine whether an hAd5-SARS-CoV-2 immunogenic
composition is protective (i.e., is a vaccine), one of ordinary
skill in the art can conduct an animal challenge study.
[0220] In some embodiments, an assay to determine the titer of
neutralization antibody, following vaccination of an animal model,
is performed such as a plaque reduction neutralization test (PRNT)
or focus reduction neutralization test (FRNT) which will
demonstrate induction of a protective immune response. In this
instance, serum or other biological fluids is collected from
post-vaccinated animals (e.g. with hAd5-SARS-CoV-2) and mixed with
SARS-CoV-2 suspension and incubated for a time period to allow the
serum antibodies to react with SARS-CoV-2. The serum
antibody/SARS-CoV-2 mixture is poured over a confluent monolayer of
host (i.e. SARS-CoV-2 permissive) cells. The surface of the cell
layer is covered in a layer of agar or carboxymethyl cellulose to
prevent the SARS-CoV-2 virus from spreading indiscriminately. The
concentration of plaque forming units (pfu) can be estimated by the
number of plaques (regions of infected cells) formed after a few
days. The plaque forming units may be measured by microscopic
observation, fluorescent antibodies or specific dyes that react
with infected cells. The concentration of serum to reduce the
number of plaques by 50% compared to the serum free virus gives the
measure of how much neutralization antibody is present or how
effective it is (i.e. protective). This measurement is denoted as
the PRNT.sub.50 value. Additionally, in an FRNT assay, virus may be
visualized using antibody labeling to similarly calculate the
FRNT.sub.50. Other methods using a pseudo-virus neutralization
assay or an ACE-2 binding inhibition assay can be used to quantity
the presence of neutralizing antibodies against SARS-CoV-2.
[0221] In certain embodiments, the present immunogenic composition
(e.g., vaccine) comprises an effective amount of about 10.sup.7
viral particles (vp) or infectious units (ifu) (e.g., at least
1.times.10.sup.7, or at least 1.times.10.sup.8, or at least
1.times.10.sup.9, or at least 1.times.10.sup.10, or at least
1.times.10.sup.11 vp or ifu) of a replication deficient adenoviral
vector. In exemplary embodiments, the present immunogenic
composition (e.g., vaccine) comprises an effective amount of about
10.sup.8 viral particles (vp) of a replication deficient adenoviral
vector. In certain other exemplary embodiments, the present
immunogenic composition (e.g., vaccine) comprises an effective
amount of about 10.sup.9 viral particles (vp) of a replication
deficient adenoviral vector. In certain other exemplary
embodiments, the present immunogenic composition (e.g., vaccine)
comprises an effective amount of about 10.sup.10, or greater, viral
particles (vp) of a replication deficient adenoviral vector. In
certain other exemplary embodiments, the present immunogenic
composition (e.g., vaccine) comprises an effective amount of about
10.sup.11, or greater, viral particles (vp) of a replication
deficient adenoviral vector. In some embodiments, the mammal is a
companion or domesticated or food-producing or feed-producing or
livestock or game or racing or sport animal such as a cow, a dog, a
cat, a goat, a sheep, a rabbit, or a pig or a horse, or even fowl
such as turkey, ducks or chicken. In exemplary embodiments the
mammalian subject is a human.
[0222] Methods of Use
[0223] Provided herein is a method for inducing an immune response
against coronavirus, the method comprising administering an
effective amount of the SARS-CoV-2 immunogenic composition to a
mammalian subject. In certain embodiments, is provided a method for
transmucosal administration of a pharmaceutical dose of a present
therapeutic/immunogenic composition (e.g., vaccine) configured to
induce an immune response (e.g., a protective immune response as a
vaccine) via intranasal administration. In certain embodiments the
present immunogenic compositions comprise a replication defective
adenoviral vector comprising an expression cassette comprising a
coding sequence encoding at least one coronavirus antigen or at
least one immunogenic fragment thereof, wherein the coding sequence
encodes at least one or more B cell epitopes, one or more CD8+ T
cell epitopes, and/or one or more CD4+ T cell epitopes. In
exemplary embodiments the mammalian subject is a human being and
the coronavirus antigen is from SARS-CoV-2. In some embodiments,
the mammalian subject is a human being infected by SARS-CoV-2
(e.g., a hospitalized human being). In some embodiments, the
SARS-CoV-2 immunogenic composition can be used to treat SARS-CoV-2
infection (e.g., in such an infected and/or hospitalized human
being).

this disclosure to, in a mammal, preferably a human being: induce
an anti-SARS-CoV-2 immune response, preferably statistically
significant anti-SARS-CoV-2 immune response; induce a protective

anti-SARS-CoV-2 immune response with an acceptable safety profile;
confer prophylactic therapy against SARS-CoV-2; reduce the rates of
intensive care unit (ICU) admission and mechanical ventilation in
patients with early onset COVID-19; reduce the severity of COVID-19
in patients with early onset COVID-19 who require hospitalization;
inhibit, suppress and/or prevent the development of a "cytokine
storm" during infection by SARS-CoV-2 (in preferred embodiments,
co-administering one or more of immunogenic compositions with one
or more anti-cytokine reagents); induce significant decreases
(e.g., as compared to placebo controls) in IL-1.alpha., IL-6,
and/or IL-12p70, and/or pulmonary interstitial inflammation in a
patient having COVID-19 (i.e., a patient infected with SARS-CoV-2);
accelerate the time to clinical improvement and/or recovery in
patients (e.g., hospitalized patients) infected with SARS-CoV-2;

embodiments, IgG and/or IgA); induce anti-SARS-CoV-2 T cell
immunity (e.g., systemic and/or mucosal); induce bone marrow and
lung resident memory antibody secreting cells; induce an immune
response (e.g., neutralizing antibodies and/or T cell immunity)
that is effective and/or can be detected for at least 4 months, for
at least about 5 months, at least about 6 months, at least about 7
months, at least about 8 months, at least about 9 months, at least
about 10 months, at least about 11 months, or at least about 12
months; and/or, provide for repeated administration (e.g., as a
seasonal vaccine administered about once every 11-14 months)
without inducing a significant immune response against the
adenoviral vector itself.
[0225] Dosage of the immunogenic composition (e.g., Ad-vector
SARS-CoV-2 vaccine) when used with or without an adjuvant may range
from about 10.sup.7 to about 10.sup.12 infectious unit or plaque
forming unit (ifu or pfu), or the dosage unit may be a viral
particle (vp), wherein 1 vp equals about 1-100 ifu or pfu. In one
embodiment the dose of Ad-vector SARS-CoV-2 immunogenic composition
or vaccine administered to the mammalian subject is about, or at
least about, 10.sup.7 vp or infectious units (ifu) (e.g., at least
1.times.10.sup.7, or at least 1.times.10.sup.8, or at least
1.times.10.sup.9, or at least 1.times.10.sup.10, or at least
1.times.10.sup.11 vp or ifu). In another aspect the dose of
Ad-vector SARS-CoV-2 immunogenic composition or vaccine
administered to the mammalian subject is about, or at least about,
10.sup.8 vp. In yet another aspect, the dose of Ad-vector
SARS-CoV-2 immunogenic composition or vaccine administered to the
mammalian subject is about, or at least about, 10.sup.9 vp. In
another aspect the dose of Ad-vector SARS-CoV-2 immunogenic
composition or vaccine administered to the mammalian subject is
about, or at least about, 10.sup.10 vp. In another aspect the dose
of Ad-vector SARS-CoV-2 immunogenic composition or vaccine
administered to the mammalian subject is about, or at least about,
10.sup.11 vp. In another aspect the dose of Ad-vector SARS-CoV-2
immunogenic composition or vaccine administered to the mammalian
subject is about, or at least about, 10.sup.12 vp.
[0226] One of skill in the art understands that an effective dose
in a mouse may be scaled for larger animals such as a human, dogs,
pigs, non-human primates, minks, ferrets, cats, horses/equines,
etc.; and, these larger animals are subjects for administration in
accordance with this disclosure. In that way, through allometric
scaling (also referred to as biological scaling) a dose in a larger
animal may be extrapolated from a dose in a mouse to obtain an
equivalent dose based on body weight or body surface area of the
animal.
[0227] In certain embodiments, non-invasive administration of the
Ad-vector SARS-CoV-2 immunogenic composition or vaccine includes,
but is not limited to, topical application to the skin, and/or
intranasal and/or mucosal and/or perlingual and/or buccal and/or
oral and/or oral cavity administration. Dosage forms for the
application of the Ad-vector SARS-CoV-2 immunogenic composition or
vaccine may include liquids, ointments, powders and sprays. The
active component may be admixed under sterile conditions with a
physiologically acceptable carrier and any preservative, buffers,
propellants, or absorption enhancers as may be needed.
[0228] In certain embodiments provided herein is a method for
transmucosal administration of a therapeutic dose of a
non-replicating viral vectored immunogenic composition (e.g.,
vaccine) to a human subject, wherein the method comprises
administering intranasally to the human subject the immunogenic
composition (e.g., vaccine) comprising an effective amount of at
least 10.sup.7 viral particle (vp) or infectious units (ifu) (e.g.,
at least 1.times.10.sup.7, or at least 1.times.10.sup.8, or at
least 1.times.10.sup.9, or at least 1.times.10.sup.10, or at least
1.times.10.sup.11 vp or ifu) of replication deficient adenovirus
vector that contains and expresses a heterologous SARS-CoV-2
antigen codon optimized for the mammalian subject; whereby the
therapeutic dose administered transmucosally induces a protective
immune response.
[0229] In embodiments, for (trans)mucosal administration
compositions may be in a form and dispensed by a squeeze spray
dispenser, pump dispenser, multi-dose dispenser, dropper-type
dispenser or aerosol dispenser. Such dispensers may also be
employed to deliver the composition to oral or oral cavity (e.g.,
buccal or perlingual) mucosa. Aerosols are usually under pressure
by means of a hydrocarbon. Pump dispensers may preferably dispense
a metered dose or, a dose having a particular particle size. The
distribution of aerosol particle/droplet size can be expressed in
terms of either: the mass median aerodynamic diameter (MMAD)--the
droplet size at which half of the mass of the aerosol is contained
in smaller droplets and half in larger droplets; volumetric mean
diameter (VIVID); mass median diameter (MMD); or the fine particle
fraction (FPF)--the percentage of particles that are <5 um in
diameter. These measurements may be made by impaction (MMD and
MMAD) or by laser (VIVID). For liquid particles, VMD, MMD and MMAD
may be the same if environmental conditions are maintained, e.g.,
standard humidity. However, if humidity is not maintained, MMD and
MMAD determinations will be smaller than VIVID due to dehydration
during impactor measurements. For the purposes of this description,
VMD, MMD and MMAD measurements are considered to be under standard
conditions such that descriptions of VIVID, MMD and MMAD will be
comparable. Particles having a mass median aerodynamic diameter
(MMAD) of greater than about 5 microns generally do not reach the
lung; instead, if administered orally they tend to impact the back
of the throat and are swallowed and possibly orally absorbed; and,
particles of this size administered nasally will lodge in the nasal
mucosa. Particles having diameters of about 1 to about 5 microns
are small enough to reach the upper- to mid-pulmonary region
(conducting airways) but are too large to reach the alveoli.
Smaller particles, i.e., about 0.5 to about 2 microns, are capable
of reaching the alveolar region. Particles having diameters smaller
than about 0.5 microns can also be deposited in the alveolar region
by sedimentation, although very small particles may be exhaled.
Depending on whether the desire is to mucosally administer to the
nasal mucosa or into the upper-to-mid pulmonary region or into the
alveoli, the skilled person can achieve any or all of these targets
from this disclosure and the knowledge in the art. In addition, for
intranasal administration an atomizer device, such as a LMA MAD300
from Teleflex LLC (Intranasal Mucosal Atomization Device LMA.TM.
#MAD300 Nasal Device Without Syringe, 1.65 inch length, and 0.17
tip diameter) can advantageously be employed. An aerosol device or
dispenser such as an atomizer that delivers a mist having a typical
particle size of about 30 to about 100 microns to the olfactory
mucosa or nasal mucosal membranes can advantageously be employed in
the practice of the invention, and advantageous particle sizes of
droplets of formulations of this disclosure for the practice of the
invention can be from about 30 to about 100 microns, e.g., about 30
or about 40 or about 50 to about 60 or about 70 or about 80 or
about 90 or about 100 microns, for intranasal administration.
[0230] In embodiments, the present SARS-CoV-2 pharmaceutical
formulation is used to provide protection against seasonal
coronavirus. In certain other embodiments, the present CoV
pharmaceutical formulation is used to provide protection against
pandemic SARS-CoV-2. In certain other embodiments, the present
SARS-CoV-2 pharmaceutical formulation is used to provide protection
against SARS-CoV-2. In embodiments, the seroprotection lasts at
least about 1 month, 2 months, 4 months, 6 months, 8 months, 10
months, 12 month or at least about 13 months.
[0231] In some embodiments, is provided a method for inducing an
immune response against coronavirus, the method comprising
administering a single dose of a present immunogenic
composition/formulation/dosage to a mammalian subject (e.g. human).
In certain embodiments, the method comprises intranasal
administration of an effective amount of the immunogenic
composition to the mammalian subject, wherein the immune response
provides protection against challenge with SARS-CoV-2. In certain
embodiments, is provided a method of inducing a combined mucosal,
humoral and/or T cell protective immune response in a human subject
against coronavirus comprising administering intranasally to a
human subject a single dose of the SARS-CoV-2 pharmaceutical
formulation (immunogenic composition), or a pharmaceutical dosage
thereof, wherein the administration induces serum antibodies,
mucosal antibodies and T cells against coronavirus. In embodiments,
the human subject is seroprotected at least about 1 month, 2
months, 4 months, 6 months, 8 months, 10 months, 12 month or at
least about 13 months. In certain embodiments, the human subject is
seroprotected for at least about 9 months.
[0232] In alternative embodiments, is provided a method for
inducing an immune response against coronavirus wherein the method
comprises administering at least a prime and boost dose of a
present immunogenic composition/formulation/dosage. In certain
embodiments, the boost dose is administered about 2 weeks, 3 weeks,
4 weeks, 5 weeks, 6 weeks, 7 weeks, 8 weeks, 9 weeks, 10 weeks, 11
weeks, 12 weeks, 13 weeks, 14 weeks, 15 weeks, 16 weeks, 17 weeks,
18 weeks, 19 weeks, 20 weeks, 21 weeks, 22 weeks, 23 weeks, 24
weeks, 25 weeks, 26 weeks, 27 weeks, 28 weeks, 29 weeks, 30 weeks,
31 weeks, 32 weeks, 33 weeks, 34 weeks, 35 weeks, 36 weeks, 37
weeks, 38 weeks, 39 weeks, 40 weeks, 41 weeks, 42 weeks, 43 weeks,
44 weeks, 45 weeks, 46 weeks, 47 weeks, 48 weeks, 49 weeks, 50
weeks, 51 weeks or 52 weeks after administration of the prime
dose.
[0233] In embodiments, the prime boost doses are homologous,
meaning they are the same formulation. In certain embodiments, the
methods and compositions provided include administering a
heterologous immunogenic composition or vaccine prime dose and
boost dose leading to an induction of an immune response (e.g., T
cell, humoral and/or mucosal) where "heterologous" means a prime
dose that is different than a boost dose, provided both comprise at
least one, or more, of the SARS-Cov-2 antigen epitopes. In certain
embodiments, that means a prime dose and boost dose wherein the
antigen/immunogens/peptides are presented to the immune system via
different delivery carriers and/or vectors. As used herein, a
"heterologous dosing regimen", means a prime dose and boost dose
wherein the antigen/immunogens/peptides are presented to the immune
system via different delivery carriers and/or vectors. For example,
in the instant invention a first composition (as either a prime
dose or a boost dose) comprises a viral vectored antigen or
immunogen, and a second composition (as either a prime dose or a
boost dose) comprises fluorocarbon-linked peptides, wherein the
peptide comprises one or more T cell epitopes in common with the
viral vectored antigen or immunogen. In other words, in certain
embodiments, the present immunogenic composition or vaccine
combination is two different T cell inducing immunogenic
composition or vaccine compositions, wherein each composition
induces antigen specific CD8+ T cells against the same antigen. In
alternative embodiments, a first composition (as either a prime
dose or a boost dose) comprises a viral vectored antigen or
immunogen, and a second composition (as either a prime dose or a
boost dose) comprises an RNA immunogenic composition or vaccine
composition such as a composition comprising a modified mRNA, a
unmodified mRNA or a self-amplifying mRNA formulated in liposomes
or lipid nanoparticles., a DNA composition administered by
electroporation or using a lipid based formulation, a live
attenuated immunogenic composition or vaccine composition, a
protein-based composition formulated or not with an adjuvant or
delivery system, a killed immunogenic composition or vaccine
composition, a different adenoviral vectored immunogenic
composition or vaccine composition such as HAdV-1 to 57, a simian
adenovirus or a non-adenoviral vector such as but not limited to an
adeno-associated virus (AAV), a lentivirus or a poxvirus. The first
composition can be administered first to prime the immune response
locally or systemically and the second immunogenic composition or
vaccine such as the adenovirus can be administered mucosally as a
booster to "pull" the primed immune cells locally and re-stimulated
them in an antigen specific manner.
[0234] In embodiments, the prime and boost dose are administered at
least 7 days apart, at least 14 days apart, or longer. In
embodiments, the prime dose and boost dose are administered about 7
days apart, about 14 days apart, about 20 days apart, about 25 days
apart, about 30 days apart, about 35 days apart, about 40 days
apart, about 45 days apart, about 50 days apart, about 55 days

the doses are administered about 40 days apart, about 41 days
apart, about 42 days apart, about 43 days apart, about 44 days
apart, about 45 days apart, about 46 days apart, about 47 days
apart, about 48 days apart, about 49 days apart or about 50 days
apart. In certain embodiments, the prime dose and boost dose are
administered about 1 week apart, about 2 weeks apart, about 3 weeks
apart, about 4 weeks apart, about 5 weeks apart, about 6 weeks
apart, about 7 weeks apart, about 8 weeks apart, about 9 weeks
apart, about 10 weeks apart, about 11 weeks apart or about 12 weeks
apart. In certain other embodiments, the prime dose and boost dose
are administered about 1 month apart, about 2 months apart, about 3
months apart, about 4 months apart, about 5 months apart, about 6
months apart, about 7 months apart, about 8 months apart, about 9
months apart, about 10 months apart, about 11 months apart, or
about 12 months apart.
[0235] In embodiments, the first or second immunogenic composition
or vaccine composition is administered as a prime and boost dose
administered at least 7 days apart, at least 14 days apart, or
longer. In embodiments, the prime dose and boost dose are
administered about 7 days apart, about 14 days apart, about 20 days
apart, about 25 days apart, about 30 days apart, about 35 days
apart, about 40 days apart, about 45 days apart, about 50 days
apart, about 55 days apart, about 60 days apart or about 65 days
apart. Advantageously, the doses are administered about 40 days
apart, about 41 days apart, about 42 days apart, about 43 days
apart, about 44 days apart, about 45 days apart, about 46 days
apart, about 47 days apart, about 48 days apart, about 49 days
apart or about 50 days apart. In certain embodiments, the prime
dose and boost dose are administered about 1 week apart, about 2
weeks apart, about 3 weeks apart, about 4 weeks apart, about 5
weeks apart, about 6 weeks apart, about 7 weeks apart, about 8
weeks apart, about 9 weeks apart, about 10 weeks apart, about 11
weeks apart or about 12 weeks apart. In certain other embodiments,
the prime dose and boost dose are administered about 1 month apart,
about 2 months apart, about 3 months apart, about 4 months apart,
about 5 months apart, about 6 months apart, about 7 months apart,
about 8 months apart, about 9 months apart, about 10 months apart,
about 11 months apart, or about 12 months apart.
[0236] In some embodiments, rdAd anti-SARS-CoV-2 vectors (e.g., a
SARS-CoV-2 immunogenic composition (which can include more than one
type of rdAd anti-SARS-CoV-2 vector)) can be administered with one
or more anti-cytokine reagents. As shown in Example 2,
administration of AdE to mice was shown to decrease the expression
of cytokines known to be involved in the progression and symptoms
of infectious diseases caused by viruses such as influenza. For
instance, AdE can cause an increase in the expression of monocyte
chemoattractant protein (MCP-1 (CCL2)), interferon gamma
(IFN-.gamma.), and RANTES (CCL5) upon administration to
non-infected mammals, which can be accompanied by a decrease in
IL-12 expression. Three days after exposure to influenza, animals
to which AdE was administered were found to exhibit decreased
expression of IL-1.alpha., IL-6, IL-12, MCP-1, with a significant
decrease of IL-1.alpha., and IL-12. Six (6) days after exposure to
influenza, the animals exhibited decreased expression of IL-5,
IL-6, IL-12, IL-17, MCP-1 and GM-CSF, and increased expression of
macrophage inflammatory protein 1 alpha (MIP-1.alpha. (CCL3)) and
RANTES (CCL5). These results are consistent with the development of
a "cytokine storm" during infection by SARS-CoV-2. In some
embodiments, then, to prevent and/or treat SARS-CoV-2 infection, a
SARS-CoV-2 immunogenic composition can be administered to a mammal,
such as a human being, with one or more anti-cytokine reagent(s)
(i.e., co-administered). Such co-administration can be carried out
as single mixture (e.g., one or more anti-cytokine reagents can be
included in the SARS-CoV-2 immunogenic composition), or as separate
compositions administered essentially simultaneously and/or at or
near the same anatomical site, or at different anatomical sites by
an appropriate route (e.g., intranasal administration of the
SARS-CoV-2 immunogenic composition and intradermal or intravenous
administration of the one or more anti-cytokine reagent(s)), and in
an effective amount that can vary for each type of anti-cytokine
reagent (and as is known in the art). In some embodiments, the
SARS-CoV-2 immunogenic composition can be administered as a single
dose, as can the one or more anti-cytokine reagents. In some
embodiments, the one or more anti-cytokine reagents can be
administered multiple times (e.g., any of about 7, 14, 21 days, or
any of about one, two or three months) after administration of the
SARS-CoV-2 composition including, in some embodiments, an initial
administration with the SARS-CoV-2 composition. Exemplary
anti-cytokine reagents for administration to a mammal to prevent
and/or treat SARS-CoV-2 can therefore include, but are not limited
to, one or more anti-IL-1a reagent(s), one or more anti-IL5
reagent(s), one or more anti-IL-6 reagent(s), one or more
anti-IL-12 reagent(s), one or more anti-IL-17 reagent(s), one or
more anti-MCP-1 reagent(s), one or more anti-TNF-.alpha.
reagent(s), one or more anti-GM-CSF reagent(s), and/or one or more
anti-RANTES reagent(s). In some embodiments, the one or more
anti-cytokine reagents would not include one or more
anti-MIP.alpha. reagent(s) and/or one or more anti-RANTES
reagent(s). Exemplary anti-cytokine reagents that can be used as
described herein can include, for example, any of those shown in
Table 10.

[0237] In some embodiments, one or more additional anti-SARS-CoV-2
agents can also be administered to the subject(s) before,
essentially simultaneously, or after administration of SARS-CoV-2
immunogenic composition such as, for instance, chloroquine (e.g.,
pharmaceutical salt and/or derivative thereof; e.g.,
hydroxychloroquine 400 mg per day for 5 days or 200 mg three times
per day for 10 days) and/or azithromycin (e.g., 500 mg on first day
followed by four daily 250 mg doses) and/or remdesivir (e.g., 200
mg initial followed by 100 mg daily doses) and/or one or more
anti-inflammatories (e.g., prednisone, dexamethasone) and/or any
other suitable reagent. Other administration/dosing schemes,
anti-cytokine reagents, combinations thereof, and combinations with
other anti-SARS-CoV-2 agents as are available to those of ordinary
skill in the art can be suitable for use as disclosed herein, as
would be understood by those of ordinary skill in the art.
[0238] In some embodiments, a subject (e.g., human being) can be
tested for coronavirus infection by a suitable technique (e.g.,
polymerase chain reaction (PCR), nasal swab to detect viral
particles). An immunogenic composition comprising one or more rdAd
anti-SARS-CoV-2 vectors (e.g., as viral particles; SARS-CoV-2
immunogenic composition) can then be administered to individuals
that test positive for coronavirus infection. Preferably, such
administration can be completed within seven to ten days after
initial exposure to the coronavirus. In some embodiments, a
SARS-CoV-2 immunogenic composition comprising one or more rdAd
anti-SARS-CoV-2 vectors (e.g., as viral particles) can be
administered to individuals at high risk for infection and/or
symptoms (e.g., respiratory symptoms, death) such as
immunocompromised individuals and/or suffering from another disease
condition (e.g., kidney failure), and/or persons in high risk
situations (e.g., travelers to pandemic areas, enclosed spaces such
as cruise ships), whether or not such individuals have tested
positive for coronavirus infection.
[0239] In some embodiments, the compositions disclosed herein can
be administered to a host comprising nostrils, wherein such
nostrils are tilted upwards (i.e., the dorsal position), to
generate a strong immunogenic response via intranasal
administration. Other administration and dosing strategies are also
contemplated herein as would be understood by those of ordinary
skill in the art.
[0240] In some embodiments, this disclosure provides an immunogenic

rdAd vector comprises an expression cassette encoding at least one
SARS-CoV-2 antigen different from that encoded by the other types
of rdAd vectors in the combination, wherein the rdAd vectors are
administered together or separately; wherein said immunogenic
composition is configured to induce neutralizing antibody and/or
cellular immune response against SARS-CoV-2 in a mammalian subject
to which said immunogenic composition is administered. In some
embodiments, the immunogenic composition can comprise a combination
of any two of the rdAd vectors of a)-c), such as in a two-part
composition comprising at least one composition comprising rdAd
vectors of a)-c) and at least a second composition comprising a
different rdAd vector of a)-c). In some embodiments, the expression

Example 1: Materials and Methods
[0369] Recombinant replication deficient adenovirus type 5.
Replication defective human Adenovirus 5 (hAd5) are generated using
previously described methods (Miravet, et al. Methods Mol Biol
2014, 1089, 159-173). In brief, the defective hAd5 lacks E1 and E3
genes to allow genomic space for the transgene insert. In some
embodiments, the hAd5 lacks coding sequences for any exogenous
antigens (i.e., non adenoviral antigens as in the AdE vector). In
some embodiments, the hAd5 encodes one or more SARS-CoV-2
antigen(s) (referred to herein as "hAd5-SARS-CoV-2"). In some
embodiments, the hAd5 encodes one or more influenza antigen(s) (as
in the AdD vector). The hAd5-SARS-CoV-2 vectors and AdD vectors can
encode any SARS-CoV-2 or influenza antigen, respectively, that is
immunogenic regarding such antigen(s) in a human being or non-human
animal (e.g., a mammal). For instance, the SARS-CoV-2 antigen
insert can encode any protein (and/or any one or more fragment(s)
and/or derivative(s) thereof) encoded by SEQ ID NO:1 (FIGS. 1A-J),
such as any one or more of SEQ ID Nos. 2-11, 13 or 15 and/or any
one or more fragments and/or derivatives thereof (e.g., a peptide
of at least 3, 6, 9 or 11 contiguous amino acids thereof). The
expression cassette is a cytomegalovirus (CMV) immediate early
driven transgene, optionally encoding a tissue plasminogen
activator signal sequence (tPA), followed by a codon optimized
SARS-CoV-2 spike (S) cassette, inserted into the E1 region of the
Adenovirus vector. The present immunogenic compositions are
manufactured by propagation of the RD-Ad5 vector in
replication-permissive CAP cells (Wolfel, et al. BMC Proceedings,
2011, 5(Supp 8):P133; Cevec), followed by purification of the virus
from the infected cell harvest, and the final product may include
the following excipients Tris HCl (pH 7.4), histidine, sucrose,
sodium chloride, magnesium chloride, polysorbate 80,
ethylenediaminetetraacetic acid, and ethanol, the final product
stored at -80.degree. C.
[0370] For animal and/or clinical studies, the present
pharmaceutical formulations are supplied in a single-use glass
vials each containing a nominal volume of 0.7 mL of a sterile
frozen suspension of immunogenic composition (e.g., vaccine)
formulated to deliver the nominal dose of 1.times.10.sup.7,
1.times.10.sup.8, 1.times.10.sup.9, 1.times.10.sup.10 or
1.times.10.sup.11 viral particles (vp). Alternatively, the present
pharmaceutical formulations are supplied in a single-use
(pre-filled) syringe, optionally with an atomizer, (e.g., BD
Accuspray) containing a nominal volume of 0.5 mL of a sterile
frozen suspension of immunogenic composition (e.g., vaccine)
formulated to deliver the nominal dose of 1.times.10.sup.7,
1.times.10.sup.8, 1.times.10.sup.9, 1.times.10.sup.10 or
1.times.10.sup.11 viral particles (vp).
[0371] Focus Forming Assay. hAd5 vector (e.g., AdE,
hAd5-SARS-CoV-2, AdD) titration is performed by focus forming assay
(FFA) or other suitable assay. Briefly, regarding the FFA, cells
expressing the viral receptor (e.g., ACE2 receptor (angiotensin
converting enzyme 2)) are plated the day before the assay in a
96-well plate then virus stocks, serially diluted, allowed to
infect cells, and then, optionally overlayed with methylcellulose.
The cells are incubated at 37.degree. C. for 48 hours followed by
fixation with paraformaldehyde. Immunostaining using a coronavirus
monoclonal antibody and a secondary antibody are used to visualize
the formation of foci for individual infected cells for the
hAd5-SARS-CoV-2 stock.
[0372] Western Blot. To confirm protein expression from the hAd5
(e.g., recombinant hAd5-SARS-CoV-2 virus), 293 cells (e.g, 293,
Calu-3, Caco-2 or Vero) are infected with hAd5-SARS-CoV-2. After an
incubation period (e.g., 48 hours) at 37.degree. C., 5% CO.sub.2
the cells are rinsed once with PBS and harvested using
2.times.NuPage buffer. Samples are heated at 95.degree. C. for 10
minutes, cooled, and loaded onto NuPage 4-12% gels. Protein are
transferred to nitrocellulose membrane, blocked with non-fat milk,
and probed with one or more types of primary antibodies in TBST,
each having specificity for one or more SARS-CoV-2 antigens. After
overnight incubation, membranes are washed 3 times with TBST and
blotted with fluorescently conjugated secondary antibodies
(molecular probes). After one hour in secondary, membranes are
washed three times in TB ST and one time in PBS, then fluorescent
signal are captured with an imager.
[0373] Intracellular Cytokine stain. Spleens are harvested from
vaccinated mice eight days post vaccination. Spleens are ground
over a 100 .mu.m cell strainer and brought up in RPMI with 10% FBS
and HEPES. Approximately 10.sup.6 cells are plated per well in a
round bottom 96 well plate and stimulated for 6 hours at 37.degree.
C., 5% CO.sub.2 in the presence of 10 .mu.g/ml brefeldin A and
either .alpha.-CD3 (2C11 clone) or 10 .mu.g of peptide in 90% DMSO.
Following peptide stimulation, cells are washed once with PBS and
stained for surface markers. Cells are then fixed and permeablized
and stained for intracellular markers (e.g. IFN-.gamma.). The cells
are analyzed by flow cytometry.
[0374] ELISA. Polystyrene 96-well plates are coated overnight at
4.degree. C. with 1 .mu.g/ml of SARS-CoV-2 antigen in sodium
carbonate buffer (pH 9.3). Plates are washed three times in PBS
with 0.02% Tween 20 and blocked with non-fat dried milk for one
hour at 37.degree. C. with PBS, 2% BSA, and 0.02% Tween 20. Serum
from hAd5 (e.g., hAd5-SARS-CoV-2) vaccinated mice are serially
diluted in PBS then incubated at 37.degree. C. Plates are washed
four times with PBS with 0.02% Tween 20 and incubated with labeled
secondary antibody for one hour. After washing and incubation as
needed the plates are read using a microplate reader.
[0375] Vaccination with Recombinant replication deficient
adenovirus type 5. Mice are anesthetized using Ketamine/Xylazine
(90 mg/kg: 10 mg/kg), and then vaccinated with an appropriate
volume intranasally of 1.times.10.sup.7 particles of
hAd5-SARS-CoV-2 diluted in PBS.
[0376] Animal Challenge. SARS-CoV-2 is diluted in sterile PBS pH
7.4 to obtain a suitable final concentration of SARS-CoV-2 per
mouse (e.g., those expressing the viral receptor) in a final volume
of 10-50 .mu.L. Virus challenge is performed by intranasal
administration 21 days post hAd5-SARS-CoV-2 vaccination. Mice are
anesthetized during this procedure using Ketamine/Xylazine (90
mg/kg: 10 mg/kg). After challenge, each mouse is examined for
visible trauma and, placed back into its cage for recovery.
[0377] Clinical Monitoring. Animals are observed for clinical
outcomes daily after SARS-CoV-2 challenge. Body weight changes,
symptoms of SARS-CoV-2 virus infection, and mortality are recorded
for each animal daily.
Example 2: AdE Compositions for Immunization Against Respiratory
Infection
[0378] The studies described in this example evaluated the immune
response following administration of AdE for prevention and/or
treatment of respiratory infection (e.g., as may be caused by
influenza), including measurement of serum antibody levels by
hemagglutination inhibition assay and secretory IgA levels in lung
lavage. Cellular immunity was evaluated by quantitation of cells,
in lung lavage, releasing IFN-.gamma. and IL-4 by ELISpot assay. In
addition, adenovirus-specific immunity was evaluated by adenovirus
neutralization using serum from vaccinated mice. This study
determined the ability of the empty adenovirus vector (AdE) to
provide protection against influenza A H1N1, H3N2, H5N1, and
influenza B virus challenge infections in mice. In addition,
cytokine levels in lung lavage were evaluated following vaccination
and challenge in an attempt to determine the mechanism of
protection afforded by the AdE vector.

RANTES--regulated upon activation, normal T cell expressed and
secreted.
[0381] Animals: Female six week-old BALB/c mice were obtained from
Charles River Laboratories. The mice were quarantined for 72 hours
before use and maintained on Teklad Rodent Diet (Harlan Teklad) and
tap water at the Laboratory Animal Research Center of Utah State
University.
[0382] Virus: Influenza A/California/04/2009 (pandemic H1N1),
strain designation 175190, was received from Dr. Elena Govorkova,
Department of Infectious Diseases, St. Jude Children's Research
Hospital, Memphis Tenn. The virus was adapted to replication in the
lungs of BALB/c mice by 9 sequential passages through mouse lungs.
Virus was plaque purified in Madin-Darby canine kidney (MDCK) cells
(American Type Culture Collection, Manassas, Va.) and a virus stock
was prepared by growth in embryonated chicken eggs and then MDCK
cells. Influenza A/Victoria/3/75 (H3N2) virus was obtained from the
American Type Culture Collection (Manassas, Va.). The virus became
lethal to mice after seven serial passages in the lungs of infected
animals. Following mouse-adaptation a virus stock was prepared by
growth in MDCK cells. Influenza A/Vietnam/1203/2004 (H5N1) was
obtained from the Centers for Disease Control (Atlanta, Ga.). Viral
propagation and assays were done in MDCK cells. Parent virus was
passaged once to prepare a challenge pool. Influenza
B/Sichuan/379/99 virus was obtained from the Centers for Disease
Control (Atlanta, Ga.). The virus was propagated twice in MDCK
cells, and then passaged serially 10 times in mice. Following
mouse-adaptation a virus stock was prepared by growth in MDCK
cells.
[0383] AdE Composition: The virus titer for the AdE was
6.4.times.10.sup.9 infection forming units (ifu)/ml
(3.2.times.10.sup.8 ifu/0.05 ml). The vaccine was administered by
the intranasal route in a 50 .mu.l volume on a single occasion (see
experimental design).
[0384] Experimental design: Animal numbers and study groups are
described in Tables 1 to 3. Groups of mice were vaccinated on study
day 0 or 20 by the intranasal route. The placebo groups received 50
.mu.l physiological sterile saline (PSS) by the same route. For
influenza virus challenge, mice were anesthetized by i.p. injection
of ketamine/xylazine (50 mg/kg//5 mg/kg) prior to intranasal
challenge with 90 .mu.l of influenza A/CA/04/2009 (H1N1p),
A/Victoria/3/1975 (H3N2), B/Sichuan/379/1999 or 75 .mu.l of
influenza A/Vietnam/1203/2004 (H5N1). The challenge dose was
approximately 3.times.LD50 CCID50 (cell culture infectious doses)
of virus per mouse. All mice were administered virus challenge on
study day 22. Following challenge all mice were observed for weight
loss and mortality through day 21 post-challenge.

[0385] Groups of mice were vaccinated on study day 0 or 20 by the
intranasal route. The placebo groups received 50 .mu.l
physiological sterile saline (PSS) by the same route. For influenza
virus challenge, mice were anesthetized by i.p. injection of
ketamine/xylazine (50 mg/kg//5 mg/kg) prior to intranasal challenge
with 90 .mu.l of influenza A/CA/04/2009 (H1N1p), A/Victoria/3/1975
(H3N2), B/Sichuan/379/1999 or 75 .mu.l of influenza
A/Vietnam/1203/2004 (H5N1). The challenge dose was approximately
3.times.LD50 CCID50 (cell culture infectious doses) of virus per
mouse. All mice were administered virus challenge on study day 22.
Following challenge all mice were observed for weight loss and
mortality through day 21 post-challenge.
[0386] Statistical analysis: Kaplan-Meier survival curves were
generated and compared by the Log-rank (Mantel-Cox) test followed
by pairwise comparison using the Gehan-Breslow-Wilcoxon test in
Prism 5.0f (GraphPad Software Inc., La Jolla, Calif.). The mean
body weights were analyzed by analysis of variance (ANOVA) followed
by Tukey's multiple comparison test using Prism 5.0f.
[0387] Bronchioalveolar lavage (BAL): The lavage procedure was
begun immediately after blood collection and was completed within 5
to 10 min of each animal's death. A volume of 0.75 ml of phosphate
buffered saline (PBS) was slowly delivered into the lung through
the tracheal tube. Immediately after delivery the fluid was slowly
withdrawn by gentle suction and the samples stored at -80. The
procedure was repeated a total of three times and lavage fluids
from each mouse were pooled.
[0388] Lung virus titer determination: BAL samples were centrifuged
at 2000.times.g for 5 minutes. Varying 10-fold dilutions of BAL
supernatants were assayed in triplicate for infectious virus in
MDCK cells, with virus titers calculated as described previously
(1, 2). Virus titer differences were evaluated by ANOVA on
log-transformed values assuming equal variance and normal
distribution. Following ANOVA, individual treatment values were
compared to placebo control by Tukey's pair-wise comparison test
using Prism 5.0f.
[0389] Lung cytokine/chemokine determinations: A sample (200 .mu.l)
from each lung lavage was tested for cytokines and chemokines using
a chemiluminescent ELISA-based assay according to the
manufacturer's instructions (Quansys Biosciences Q-Plex.TM. Array,
Logan, Utah). The Quansys multiplex ELISA is a quantitative test in
which 16 distinct capture antibodies have been applied to each well
of a 96-well plate in a defined array. Each sample supernatant was
tested at 2 dilutions for the following: IL-1.alpha., IL-10, IL-2,
IL-3, IL-4, IL-5, IL-6, IL-10, IL-12p70, IL-17, MCP-1, IFN-g,
TNF-a, MIP-1a, GM-CSF, and RANTES.
[0390] Cytokine and chemokine titers are reported in pg/ml of lung
lavage fluid. Titer differences were evaluated by ANOVA on values
assuming equal variance and normal distribution. In addition,
treatment group mean values were evaluated by two-way ANOVA for
effects based on the day post-infection using Prism 5.0f.
Results and Discussion
[0391] This study determined the ability of the empty adenovirus
vector (AdE) to provide protection against influenza A H1N1, H3N2,
H5N1, and influenza B virus challenge infections in mice. In
addition, cytokine levels in lung lavage were evaluated following
vaccination and challenge with influenza A/CA/04/2009 (pandemic
H1N1) virus in an attempt to determine the mechanism of protection
afforded by the AdE vector. Mice were vaccinated with
3.2.times.10.sup.8 ifu/50 .mu.l of AdE by the intranasal route. A
single vaccination was given three-weeks before challenge
infection. In addition, this study evaluated the antiviral effects
of the AdE-vector when administered 2 days before challenge
infection. Following infection, all mice were observed for weight
loss and mortality through day 21 post-challenge.
[0392] The AdE vector was found to provide 100% protection from
challenge with influenza A/CA/04/2009 (pandemic H1N1) virus when
administered 20 days before challenge, and provided 80% protection
when administered two (2) days before challenge. The AdE vector
provided 90% protection from influenza A/Victoria/3/75 (H3N2) virus
when administered 20 days before challenge. However, the protection
afforded by the AdE vector administered two (2) days before
challenge was not significant. The AdE vector administered 20 days
before influenza A/Vietnam/1203/2004 (H5N1) virus challenge did not
provide protection from mortality, but did increase the mean day of
death significantly. However, no protection from influenza
A/Vietnam/1203/2004 (H5N1) was provided when the AdE vector was
administered two (2) days before challenge. The AdE vector also
provided 100% protection from influenza B/Sichuan/379/9 virus when
administered 20 days before challenge. In addition, the AdE vector
provided 90% protection when administered two (2) days before
challenge with influenza B/Sichuan/379/9 virus. The AdE vector only
provided significant protection from weight loss following
challenge by the influenza B/Sichuan/379/9 virus. Both times of AdE
administration, day 0 and day 20, provided protection from weight
loss following challenge. The groups of mice receiving AdE 20 days
before challenge showed a 1-2 log reduction in influenza
A/CA/04/2009 (pandemic H1N1) virus titer compared to placebo
controls on both days.
[0393] In an attempt to identify the immune mechanism of protection
afforded by immunization with the AdE vector, the expression of
cytokines and chemokines in lung lavage following influenza
A/CA/04/2009 (pandemic H1N1) virus infection was determined.
Expression of of IL-1.alpha., IL-10, IL-2, IL-3, IL-4, IL-5, IL-6,
IL-10, IL-12p70, IL-17, MCP-1, IFN-.gamma., TNF.alpha.,
MIP-1.alpha., GM-CSF, and RANTES were measured on days 3 and 6
post-vaccination, days 25 and 28 post-vaccination, and on days 3
and 6 post-challenge (which is the same as days 25 and 28
post-vaccination). Significant changes in cytokine and chemokine
levels were observed for IL-1.alpha., IL-6, IL-12p70, MCP-1,
IFN-.gamma., and RANTES. Significant decreases, compared to placebo
controls, were observed after challenge infection for IL-1.alpha.,
IL-6, and IL-12p70. No significant changes were observed for IL-1b,
IL-2, IL-3, IL-4, IL-5, IL-10, IL-17, TNF-.alpha., MIP-1.alpha.,
and GM-CSF. A significant decrease (p<0.01) in IL-1a expression
was observed on day 3 post-challenge when the AdE was administered
20 days before challenge. A significant decrease (p<0.01) in
IL-6 expression in lung lavage following vaccination with AdE and
challenge was observed (e.g., on day 6 post-challenge when the AdE
was administered 20 days before challenge)). A significant decrease
(p<0.01) in IL-12p70 expression in lung lavage following
vaccination with AdE and challenge was observed on day 3
post-challenge when the AdE was administered 20 days before
challenge. Significant (p<0.01) changes in expression of MCP-1
and IFN-.gamma. in lung lavage were observed after vaccination and
after challenge infection. MCP-1 levels increased on days 3, 6, 25,
and 28 for all AdE treated groups post-vaccination. However, the
MCP-1 levels decreased on day 6 post-challenge when the AdE was
administered 20 days before challenge. IFN-.gamma. levels increased
on day 6 post-vaccination when the AdE was administered two (2)
days before challenge, and remained elevated until days 25 and 28
(p<0.001) post-vaccination when AdE was administered 20 days
before challenge. In addition, IFN.gamma. levels increased
approximately 10-fold on day 6 post-challenge when AdE was
administered two (2) days before challenge. Significant changes in
levels of RANTES were observed on days 3 (p<0.0001), 6
(p<0.001) and 25 (p<0.01) post-vaccination). This data is
summarized in Table 14.

CONCLUSIONS
[0394] This example describes the use of an empty adenovirus vector
(AdE) as a vaccine against influenza A H1N1, H3N2, H5N1, and
influenza B virus challenge infections in mice. A single
vaccination was given either three (3) weeks before challenge
infection, or two (2) days before challenge infection. Remarkably,
protection was provided against all challenge strains when the AdE
was administered 20 days before challenge. The survival effects
observed against the H5N1 virus was not actually from mortality,
but rather an increase in mean day of death. In addition,
protection was provided against the H1N1 and influenza B virus
challenge by the AdE vector, when administered two (2) days before
challenge. Protection observed two (2) days after vaccination
suggests an innate immune mechanism. However, innate immunity is
not expected to last longer than four (4) days post-infection.
Therefore, the observation that mice can be protected from virus
challenge after only two (2) days, in addition to three (3) weeks
after vaccination, suggests more than one mechanism of action. One
possible mechanism, suggested by the increased levels of MCP-1 and
IFN-.gamma. both post-vaccination and post-challenge, is that
vaccination with AdE leads to an increase in MCP-1, which recruits
monocytes, neutrophils, and/or lymphocytes, which then stimulates
production of IFN-.gamma..
Example 3: AdE Human Clinical Trial for SARS-CoV-2 Vaccination
[0395] In this example, the use of intranasal (i.n.) administration
of AdE vectors (i.e., replication deficient .DELTA.E1E3 adenovirus
type 5 (Ad5)) viral particles without an exogenous non-Ad pathogen
antigen encoded in the Ad5 genome) to confer prophylactic therapy
against SARS-CoV-2 is described. To establish the immunogenic
and/or protective capacity of an immunogenic composition comprising
AdE vectors against SARS-CoV-2, an AdE immunogenic composition
comprising AdE viral particles (vp), are administered to human
being subjects and tested for its effect on the immune response
against SARS-CoV-2 therein. To do so, a randomized, double-blind,
placebo-controlled, dose-escalation clinical trial to evaluate the
safety and immunogenicity of an AdE immunogenic composition in
healthy adults 18 to 49 years of age can be carried out. Subjects
are typically screened within 28 days of randomization (Day 1).
[0396] For instance, a study can comprise two parts; part A which
evaluates safety, and part B which evaluates immunogenicity, of the
AdE immunogenic composition. In part A, approximately 120 subjects
who meet all inclusion and no exclusion criteria and provided
written informed consent are enrolled into four sequential cohorts
of 30 subjects each defined by the AdE dose (1.times.10.sup.8,
1.times.10.sup.9, 1.times.10.sup.10, and 1.times.10.sup.11 vp).
Within each cohort (and the sentinel group in the first dose
cohort), subjects are randomized in a 4:1:1 ratio to receive one
intranasal dose of the AdE immunogenic composition (Day 1) or one
intranasal dose of placebo (normal saline) (Day 1). The AdE
immunogenic composition and placebo are administered in a
double-blind fashion. Reactogenicity can be ascertained by
determining counts and percentages of subjects with local events
including but not limited to nasal irritation, sneezing, nasal
congestion, cough, sore throat, change in smell, change in taste,
change in vision, eye pain, pain, tenderness, induration, erythema,
regional lymphadenopathy, and systemic events (headache, fatigue,
myalgia, nausea, vomiting, diarrhea, coughing, chills, fever) for
14 days after vaccination. Adverse Events (AEs) are determined as
counts and percentages of subjects with AEs from Day 1 to Day 57;
medically attended AEs (MAAEs), serious AEs (SAES), and new-onset
chronic illnesses (NCIs) from Day 1 to Day 181 following
administration of the AdE immunogenic composition. For instance,
targeted and symptom-driven physical examinations including vital
signs can be carried out on days 4, 8, 15, 22, 29, and 57; an
electrocardiogram can be carried out on day 57; safety laboratory
tests can be carried out on days 8 and 57; and serum samples taken
for immunogenicity testing at days 8, 15, 22, 29, 57, 91, 181, and
361. The primary endpoint for evaluation of the safety profile in
Part A is the number and percentage (95% confidence interval (CI))
of subjects with solicited and unsolicited AEs recorded
postvaccination. Safety analyses is performed using the Safety
Population. The number (percentage, 95% CI) of subjects with local
events and systemic events is summarized by group, as is
reactogenicity. The number (percentage, 95% CI) of subjects with
AEs from Day 1 to Day 57 (including MAAEs, NCIs, SAES) is
summarized for each Medical Dictionary for Regulatory Activities
system organ class (SOC) by preferred term (PT) and group. The
number (percentage) of subjects with MAAEs, with NCIs, and with
SAES from Day 1 to Day 181 is summarized in a similar fashion. The
number (percentage, 95% CI) of subjects with AEs by severity and by
relationship to investigational product (IP) is also summarized.
Listings of AEs, MAAEs, NCIs, and SAES are provided.
[0397] In part B, the immunogenicity of the AdE immunogenic
composition is determined. Following administration of the AdE
immunogenic composition by intranasal spray as a single dose of
1.times.10.sup.8, 1.times.10.sup.9, 1.times.10.sup.10, and
1.times.10.sup.11 vp and as two doses (3 weeks apart) of the
highest well tolerated of these doses to subjects, the immune
response can be measured by ELISA of serum to measure
anti-SARS-CoV-2 antigen antibodies, and the GMT, geometric mean
ratio (GMR) (the ratio of postvaccination and pre-vaccination GMTs
within the same dose group), and responder rate (.gtoreq.four-fold
rise in IgG post dose) determined. For instance, approximately 25
subjects who meet all inclusion and no exclusion criteria and
provided written informed consent are randomized in a 4:1 ratio to
receive two intranasal doses of the AdE immunogenic composition at
the highest well tolerated dose from Part A or placebo 21 days
apart (Days 1 and 22). The AdE immunogenic composition and placebo
are administered in a double-blind fashion. Intranasal doses of the
AdE immunogenic composition and placebo are administered to
subjects in a sitting or reclined position. In part B, targeted and
symptom-driven physical examination including vital signs can be
carried out on days 8, 15, 22, 29, 36, 43, 50, and 57; an
electrocardiogram can be carried out on day 57; safety laboratory
tests on days 8, 29, and 57; serum samples taken for immunogenicity
testing at days 8, 15, 22, 29, 57, 91, 181, and 361; and
nasopharyngeal swabs collected on days 8, 15, 29, 36, 43, 50, 57,
and 91. Nasopharyngeal samples collected at Screening and on Days
29 and 57 can also be subsequently tested for evaluation of mucosal
immune response.
[0398] In some embodiments, the clinical trial can be carried out
using patients already infected by SARS-CoV-2 and time to clinical
improvement and/or recovery determined (or, in some embodiments, a
cohort of the patients tested). A primary outcome measure is Time
to Clinical Improvement (TTCI) and/or Time to Clinical Recovery
(TTCR) which are determined for up to 28 days following
administration of the AdE composition as described above. TTCI is
defined as the time (in days) from initiation of study treatment
(active or placebo) until a decline of two categories from status
at randomization on a six-category ordinal scale of clinical status
which ranges from 1 (discharged) to 6 (death). The six-category
ordinal scale is as follows: 6. Death; 5. ICU, requiring
extracorporeal membrane oxygenation (ECMO) and/or invasive
mechanical ventilation (IMV); 4. Intensive care unit
(ICU)/hospitalization, requiring non-invasive mechanical
ventilation (NIV)/high-flow nasal cannula (HFNC) therapy; 3.
Hospitalization, requiring supplemental oxygen (but not NIV/HFNC);
2. Hospitalization, not requiring supplemental oxygen; and, 1.
Hospital discharge or meet discharge criteria (discharge criteria
are defined as clinical recovery, i.e. fever, respiratory rate,
oxygen saturation return to normal, and cough relief). Secondary
outcome TTCI measures include all cause mortality (baseline SpO2
during screening, PaO2/FiO2<300 mmHg or a respiratory rate
.gtoreq.24 breaths per min without supplemental oxygen); frequency
of respiratory progression (SPO2.ltoreq.94% on room air or
PaO2/FiO2<300 mmHg and requirement for supplemental oxygen or
more advanced ventilator support); time to defervescence (in those
with fever at enrolment); time to cough reported as mild or absent
(in those with cough at enrolment rated severe or moderate); time
to dyspnea reported as mild or absent (on a scale of severe,
moderate, mild absent, in those with dyspnoea at enrolment rated as
severe or moderate,); frequency of requirement for supplemental
oxygen or non-invasive ventilation; time to SARS-CoV-2 RT-PCR
negative in throat swab, sputum, lower respiratory tract specimen,
and/or upper respiratory tract specimen; change (reduction) in
SARS-CoV-2 viral load in throat swab, sputum, lower respiratory
tract specimen, and/or upper respiratory tract specimen as assessed
by area under viral load curve (e.g., as determined using
polymerase chain reaction (PCR)); frequency of requirement for
mechanical ventilation; and, frequency of serious adverse events.
TTCI is defined as the time (in hours) from initiation of study
treatment (active or placebo) until normalization of fever,
respiratory rate, and oxygen saturation, and alleviation of cough,
sustained for at least 72 hours. The primary TTCR outcome measures
include normalization and alleviation criteria;
fever--.ltoreq.36.9.degree. C. or -axilla, .ltoreq.37.2.degree. C.
oral; respiratory rate--.ltoreq.24/minute on room air; oxygen
saturation-->94% on room air; and, cough--mild or absent on a
patient reported scale of severe, moderate, mild, absent. The
secondary TTCR outcome measures are the same as the TTCI secondary
outcomes listed above.
[0399] Standard clinical trial design and statistical methods are
used in the analyses thereof. For instance, the sample size for
this study is selected as adequate and reasonable for an initial
review of the safety and immunogenicity profile of the AdE
immunogenic composition at doses to be well tolerated, rather than
for statistical power (e.g., 120 subjects as described above). The
sample size permits initial estimates of reactogenicity. For
example, given a total of 100 subjects receiving AdE immunogenic
composition, the study is designed to have an 80% probability of
detecting at least one AE that occurred at a rate of 1.6%. If no
SAEs were observed among the 100 subjects who received AdE
immunogenic composition, an approximation to the 1-sided upper
bound of the 95% confidence interval (CI) on the rate of SAE
occurrence would be 3%. Immunology analyses are conducted using the
Evaluable and Per-protocol (PP) Populations with primary
conclusions drawn from the PP Population. Analyses based on the
Evaluable Population are undertaken and presented only if >1
subject in any one group were excluded from the PP Population. With
the exception responder analyses, as described below, no imputation
for missing data is performed. Data is transformed as appropriate
prior to analysis. Baseline is defined as the sample collected
prior to AdE immunogenic composition administration on Day 1. The
primary variables of interest for assessment of humoral and
cellular immune response to SARS-CoV-2 (e.g., cell mediated
responses) are determined. In some embodiments, comparisons of
responders in each AdE immunogenic composition dose group against
the placebo group can also be conducted using Fisher's exact test.
To determine the effect of pre-dose Ad5 serum antibody levels on
immunogenicity of AdE immunological composition on Day 29 (Part A)
or Day 50 (Part B), analyses are performed using ANCOVA with
baseline Ad5 titer as a covariate. Mucosal immunogenicity analyses
are conducted using the Evaluable and PP Populations. No imputation
for missing data is performed. Endpoints analyzed are GMT and GMR
for IgA antibody level measured by ELISA. Summary statistics for
continuous parameters (safety laboratory tests and vital signs) are
presented by group as follows: pre-vaccination, postvaccination,
and change from pre-vaccination to postvaccination assessment. The
number and percentage of subjects with postvaccination safety
laboratory values or vital sign values recorded as newly abnormal
(i.e., an event with an increase in the toxicity grade relative to
the baseline value and with a severity grade of moderate or higher)
after study vaccination are tabulated. Shift tables that
cross-tabulate the pre-vaccination and postvaccination safety
laboratory values of each subject by severity grade are prepared.
Summaries of the number and percentage of subjects with normal,
abnormal not clinically significant, and abnormal clinically
significant ECG interpretations are presented. For shedding of the
Ad5 vector, data are summarized by count and percent positive by
time point, along with median copy number. The median duration of
Ad5 shedding, interquartile range, minimum and maximum duration of
Ad5 shedding are presented for each AdE immunogenic composition
group and all immunological composition dose groups combined. Viral
culture results for evaluation of adenovirus infection are also
listed.
[0400] These studies will show that the AdE composition can be used
to induce an anti-SARS-CoV-2 immune response in human beings (e.g.,
it is an immunogenic composition), and exhibits an acceptable
safety profile. It is preferred that the immune response is
statistically significant, and even more preferably, a protective
immune response (i.e., it is a SARS-CoV-2 vaccine). In preferred
embodiments, the data shows the AdE composition can be used to
treat subjects infected by SARS-CoV-2 (e.g., hospitalized
patients).
Example 4
[0401] A. Generation of Recombinant Human Adenovirus Type 5
SARS-CoV-2 (hAd5-SARS-CoV-2)
[0402] An E1/E3 deleted, replication defective hAd5 that uses
optionally the tissue plasminogen activator (tPA) leader sequence
followed by a codon optimized nucleotide sequence encoding at least
one SARS-CoV-2 protein(s) (e.g., any one or more of SEQ ID NOS.
2-11, and/or one or more fragment(s) and/or derivative(s) thereof).
The expression cassette containing the cytomegalovirus (CMV)
promoter and SARS-CoV-2 coding sequence are inserted into the E1
region of the hAd5. This vector is referred to herein as
"hAd5-SARS-CoV-2".
[0403] To investigate the expression level of SARS-CoV-2 protein(s)
from the hAd5-SARS-CoV-2 vaccine, the expression of the SARS-CoV-2
protein(s) are compared from SARS-CoV-2-infected Vero cells by
western blot with an anti-SARS-CoV-2 rabbit polyclonal specific to
S. The western blot shows that the hAd5-SARS-CoV-2 vaccine
expresses S in infected cells. The expressed S antigen is also
sequenced to verify the native sequence.
[0404] B. Immunogenicity of hAd5-SARS-CoV-2 Vaccine.
[0405] To understand the immunogenicity of the hAd5-SARS-CoV-2
vaccine, eight-week old mice (e.g., wild type or transgenic
provided they expresses the receptor for SARS-CoV-2) are
intranasally (i.n.) immunized with sufficient number of (e.g.,
1.times.10.sup.7) hAd5-SARS-CoV-2 viral particles. On day eight,
the peak of the T cell adaptive immune response, a subset of
vaccinated mice are euthanized and SARS-CoV-2 antigen specific
CD8.sup.+ T cell responses evaluated by intracellular cytokine
staining and/or IFN-.gamma. ELISpot. Splenic or PBMCs T cells are
stimulated with peptide pools covering the antigen and/or an
immunodominant SARS-CoV-2 peptide and the frequency of
IFN-.gamma.-producing T cells are determined. Twenty-one days after
vaccination mice are bled to evaluate the serum antibody response.
A SARS-CoV-2 specific ELISA is used to determine SARS-CoV-2 S
specific immunoglobulin (IgG) responses. A single hAd5-SARS-CoV-2
vaccination may generate a SARS-CoV-2 S specific IgG response,
e.g., with a higher reciprocal mean endpoint versus naive animals
with a reciprocal mean endpoint titer below the limit of detection.
To determine the quantity of neutralizing antibodies, focus
reduction neutralization tests are completed.
[0406] C. Neutralization of SARS-CoV-2
[0407] The virus neutralizing capacity of the vaccine will be
determined using sera from immunized mice as described in section
B. of this example, using the method of plaque reduction, or
infected foci reduction. Either wild type, attenuated or
VSV-pseudo-typed with the SARS-CoV-2 S will be mixed with various
dilutions of vaccinated mouse serum and incubated for 30 min at
room temperature followed by infection of Vero or other appropriate
cell line. Virus neutralization then is quantified as the highest
antibody dilution capable of reducing the number of plaque or
infectious foci by a predetermined value, for example 50%.
[0408] D. Protective Capacity of hAd5-SARS-CoV-2 Immunogenic
Compositions
[0409] To establish the protective capacity of the SARS-CoV-2
immunogenic composition, a sufficient number of hAd5-SARS-CoV-2
viral particles (e.g., 1.times.10.sup.7) are administered i.n. to
mice or other appropriate rodent (e.g. transgenic rodent expressing
the virus receptor). Twenty-one days later the animals are
challenged with SARS-CoV-2, along with a phosphate buffered saline
(PBS)-vaccinated control group and monitored for survival. After
stringent challenge all PBS-vaccinated control mice are found to
exhibit symptoms and/or succumbed to SARS-CoV-2 infection, while
the majority of hAd5-SARS-CoV-2 vaccinated mice survive. Clinical
signs of disease are scored for twelve days and found improved in
hAd5-SARS-CoV-2 vaccinated mice compared to the non-vaccinated
controls. Such results will demonstrate that the hAd5-SARS-CoV-2
vaccine is able to induce a protective response leading to reduced
disease severity in this animal model.
[0410] E. Other
[0411] The tests described above can also be carried out using one
or more other rdAd anti-SARS-CoV-2 vectors (e.g., AdE, AdD) by
substituting hAd5-SARS-CoV-2 with another such vector (e.g., AdE,
AdD), as would be understood by those of ordinary skill in the art.
The generation and interpretation of results would be adjusted
according to the particular rdAd anti-SARS-CoV-2 vector(s) being
tested, as would be understood by those of ordinary skill in the
art.
Example 5: hAd5-SARS-CoV-2 Human Clinical Trial for SARS-CoV-2
Vaccination
[0412] To establish the immunogenic and/or protective capacity of a
hAdv5-SARS-CoV-2 immunogenic composition comprising hAd5-SARS-CoV-2
viral particles (vp) and at least one pharmaceutically acceptable
excipient, the same is administered to human subjects and tested
for its effect on the immune response against SARS-CoV-2 in such
subjects and, for its effect on time to clinical improvement and/or
recovery on patients (e.g., hospitalized patients) infected with
SARS-CoV-2. To do so, a randomized, double-blind,
placebo-controlled, dose-escalation clinical trial to evaluate the
safety and immunogenicity of hAdv5-SARS-CoV-2 composition in
healthy adults 18 to 49 years of age is carried out. Subjects are
typically screened within 28 days of randomization (Day 1).
[0413] For instance, a study can comprise two parts; part A which
evaluates safety and part B which evaluates immunogenicity of the
hAdv5-SARS-CoV-2 immunogenic composition. In part A, approximately
120 subjects who meet all inclusion and no exclusion criteria and
provided written informed consent are enrolled into four sequential
cohorts of 30 subjects each defined by the hAdv5 SARS-CoV-2 dose
(1.times.10.sup.8, 1.times.10.sup.9, 1.times.10.sup.10, and
1.times.10.sup.11 vp). Within each cohort (and the sentinel group
in the first dose cohort), subjects are randomized in a 4:1:1 ratio
to receive one intranasal dose of the hAdv5-SARS-CoV-2 immunogenic
composition (Day 1) or one intranasal dose of placebo (normal
saline) (Day 1). The hAdv5-SARS-CoV-2 immunogenic composition and
placebo are administered in a double-blind fashion. Reactogenicity
can be ascertained by determining counts and percentages of
subjects with local events including but not limited to nasal
irritation, sneezing, nasal congestion, cough, sore throat, change
in smell, change in taste, change in vision, eye pain, pain,
tenderness, induration, erythema, regional lymphadenopathy, and
systemic events (headache, fatigue, myalgia, nausea, vomiting,
diarrhea, coughing, chills, fever) for 14 days after vaccination.
Adverse Events (AEs) are determined as counts and percentages of
subjects with AEs from Day 1 to Day 57; medically attended AEs
(MAAEs), serious AEs (SAEs), and new-onset chronic illnesses (NCIs)
from Day 1 to Day 181 following administration of the
hAdv5-SARS-CoV-2 immunogenic composition. For instance, targeted
and symptom-driven physical examinations including vital signs can
be carried out on days 4, 8, 15, 22, 29, and 57; an
electrocardiogram can be carried out on day 57; safety laboratory
tests can be carried out on days 8 and 57; and serum samples taken
for immunogenicity testing at days 8, 15, 22, 29, 57, 91, 181, and
361 (e.g., enzyme-linked immunosorbent assay (ELISA) of serum to
measure anti-SARS-CoV-2 antigen antibodies, geometric mean titer
(GMT) as compared to day 0 (baseline)). Responder rates are also
determined as described below (e.g., .gtoreq.four-fold rise in IgG
post dose). The primary endpoint for evaluation of the safety
profile in Part A is the number and percentage (95% confidence
interval (CI)) of subjects with solicited and unsolicited AEs
recorded postvaccination. Safety analyses is performed using the
Safety Population. The number (percentage, 95% CI) of subjects with
local events and systemic events is summarized by group, as is
reactogenicity. The number (percentage, 95% CI) of subjects with
AEs from Day 1 to Day 57 (including MAAEs, NCIs, SAEs) is
summarized for each Medical Dictionary for Regulatory Activities
system organ class (SOC) by preferred term (PT) and group. The
number (percentage) of subjects with MAAEs, with NCIs, and with
SAEs from Day 1 to Day 181 is summarized in a similar fashion. The
number (percentage, 95% CI) of subjects with AEs by severity and by
relationship to investigational product (IP) is also summarized.
Listings of AEs, MAAEs, NCIs, and SAEs are provided.
[0414] In part B, the immunogenicity of hAdv5-SARS-CoV-2
immunogenic composition is determined. Following administration of
the hAdv5-SARS-CoV-2 immunogenic composition by intranasal spray as
a single dose of 1.times.10.sup.8, 1.times.10.sup.9,
1.times.10.sup.10, and 1.times.10.sup.11 vp and as two doses (3
weeks apart) of the highest well tolerated of these doses to
subjects, the immune response can be measured by ELISA of serum to
measure anti-SARS-CoV-2 antigen antibodies, and the GMT, geometric
mean ratio (GMR) (the ratio of postvaccination and pre-vaccination
GMTs within the same dose group), and responder rate
(.gtoreq.four-fold rise in IgG post dose) determined. For instance,
approximately 25 subjects who meet all inclusion and no exclusion
criteria and provided written informed consent are randomized in a
4:1 ratio to receive two intranasal doses of the hAdv5-SARS-CoV-2
immunogenic composition at the highest well tolerated dose from
Part A or placebo 21 days apart (Days 1 and 22). The
hAdv5-SARS-CoV-2 immunogenic composition and placebo are
administered in a double-blind fashion. Intranasal doses of the
hAdv5-SARS-CoV-2 immunogenic composition and placebo are
administered to subjects in a sitting position. In part B, targeted
and symptom-driven physical examination including vital signs can
be carried out on days 8, 15, 22, 29, 36, 43, 50, and 57; an
electrocardiogram can be carried out on day 57; safety laboratory
tests on days 8, 29, and 57; serum samples taken for immunogenicity
testing at days 8, 15, 22, 29, 57, 91, 181, and 361; and
nasopharyngeal swabs collected on days 8, 15, 29, 36, 43, 50, 57,
and 91. Nasopharyngeal samples collected at Screening and on Days
29 and 57 can also be subsequently tested for evaluation of mucosal
immune response.
[0415] The clinical trial can be carried out in patients already
infected by SARS-CoV-2 and time to clinical improvement and/or
recovery determined (or, in some embodiments, a cohort of the
patients tested). A primary outcome measure is Time to Clinical
Improvement (TTCI) and/or Time to Clinical Recovery (TTCR) which
are determined for up to 28 days following administration of the
hAdv5-SARS-CoV-2 composition as described above. TTCI is defined as
the time (in days) from initiation of study treatment (active or
placebo) until a decline of two categories from status at
randomization on a six-category ordinal scale of clinical status
which ranges from 1 (discharged) to 6 (death). The six-category
ordinal scale is as follows: 6. Death; 5. ICU, requiring
extracorporeal membrane oxygenation (ECMO) and/or invasive
mechanical ventilation (IMV); 4. Intensive care unit
(ICU)/hospitalization, requiring non-invasive mechanical
ventilation (NIV)/high-flow nasal cannula (HFNC) therapy; 3.
Hospitalization, requiring supplemental oxygen (but not NIV/HFNC);
2. Hospitalization, not requiring supplemental oxygen; and, 1.
Hospital discharge or meet discharge criteria (discharge criteria
are defined as clinical recovery, i.e. fever, respiratory rate,
oxygen saturation return to normal, and cough relief). Secondary
outcome TTCI measures include all-cause mortality (baseline SpO2
during screening, PaO2/FiO2<300 mmHg or a respiratory rate 24
breaths per min without supplemental oxygen); frequency of
respiratory progression (SPO2.ltoreq.94% on room air or
PaO2/FiO2<300 mmHg and requirement for supplemental oxygen or
more advanced ventilator support); time to defervescence (in those
with fever at enrolment); time to cough reported as mild or absent
(in those with cough at enrollment rated severe or moderate); time
to dyspnea reported as mild or absent (on a scale of severe,
moderate, mild absent, in those with dyspnea at enrollment rated as
severe or moderate,); frequency of requirement for supplemental
oxygen or non-invasive ventilation; time to 2019-nCoV-2 RT-PCR
negative in throat swab, sputum, lower respiratory tract specimen,
and/or upper respiratory tract specimen; change (reduction) in
SARS-CoV-2 viral load in throat swab, sputum, lower respiratory
tract specimen, and/or upper respiratory tract specimen; change
(reduction) in 2019-nCoV-2 viral load in in throat swab, sputum,
lower respiratory tract specimen, and/or upper respiratory tract
specimen; change (reduction) in SARS-CoV-2 viral load in throat
swab, sputum, lower respiratory tract specimen, and/or upper
respiratory tract specimen as assessed by area under viral load
curve (e.g., as determined using polymerase chain reaction (PCR));
frequency of requirement for mechanical ventilation; and, frequency
of serious adverse events. TTCI is defined as the time (in hours)
from initiation of study treatment (active or placebo) until
normalization of fever, respiratory rate, and oxygen saturation,
and alleviation of cough, sustained for at least 72 hours. The
primary TTCR outcome measures include normalization and alleviation
criteria; fever--.ltoreq.36.9.degree. C. or -axilla,
.ltoreq.37.2.degree. C. oral; respiratory rate--24/minute on room
air; oxygen saturation-->94% on room air; and, cough--mild or
absent on a patient reported scale of severe, moderate, mild,
absent. The secondary TTCR outcome measures are the same as the
TTCI secondary outcomes listed above.
[0416] Standard clinical trial design and statistical methods are
used in the analyses of the data obtained from the trial. For
instance, the sample size for this study is selected as adequate
and reasonable for an initial review of the safety and
immunogenicity profile of the hAdv5-SARS-CoV-2 composition at doses
to be well tolerated, rather than for statistical power (e.g., 120
subjects as described above). The sample size permits initial
estimates of reactogenicity. For example, given a total of 100
subjects receiving hAdv5-SARS-CoV-2 composition, the study is
designed to have an 80% probability of detecting at least one AE
that occurred at a rate of 1.6%. If no SAEs were observed among the
100 subjects who received hAdv5-SARS-CoV-2 immunological
composition, an approximation to the 1-sided upper bound of the 95%
confidence interval (CI) on the rate of SAE occurrence would be 3%.
Immunology analyses are conducted using the Evaluable and
Per-protocol (PP) Populations with primary conclusions drawn from
the PP Population. Analyses based on the Evaluable Population are
undertaken and presented only if >1 subject in any one group
were excluded from the PP Population. With the exception responder
analyses, as described below, no imputation for missing data is
performed. Data is transformed as appropriate prior to analysis.
Baseline is defined as the sample collected prior to
hAdv5-SARS-CoV-2 composition administration on Day 1. The primary
variables of interest for assessment of humoral immune response to
SARS-CoV-2 are anti-SARS-CoV-2 antigen IgG titers. GMTs are
determined at Baseline and postvaccination on Days 8, 15, 22, 29,
57, 91, and 181 (Part A) and Days 8, 15, 22, 29, 36, 43, 50, 91,
and 181 (Part B) and summarized by dose group. Comparisons between
hAdv5-SARS-CoV-2 composition doses and placebo are evaluated by
analysis of covariance (ANCOVA) with treatment as a fixed effect
and baseline log-transformed level as a covariate on the
post-baseline log-transformed level of anti-SARS-CoV-2 IgG as a
dependent variable. From these analyses, least-square (LS) means,
LS treatment differences, and 95% CIs for the treatment differences
on log-scale are obtained. The results are transformed back to the
original scale by exponentiation to provide treatment geometric LS
means, point estimates of the geometric LS mean ratios, and 95% CI
for these ratios on each study day. A "responder" is defined as a
subject with a 4-fold rise in anti-SARS-CoV-2 antigen titer from
baseline on Days 8, 15, 22, 29, 57, 91, and 181 (Part A) and Days
8, 15, 22, 29, 36, 43, 50, 91, and 181 (Part B). Fold change for
determination of responder status is computed using the
post-imputation values without the +1 transformation, i.e., fold
change=current imputed value/baseline imputed value. Responder
rates are tabulated by percentages per dose group and the 95%
Clopper-Pearson exact CI of the percentage. Differences of 95% CIs
are presented to compare the response rate of each hAdv5-SARS-CoV-2
composition dose group to the and placebo group. In some
embodiments, comparisons of responders in each hAdv5-SARS-CoV-2
composition dose group against the against the placebo group can
also be conducted using Fisher's exact test. To determine the
effect of pre-dose Ad5 serum antibody levels on immunogenicity of
hAdv5-SARS-CoV-2 composition on Day 29 (Part A) or Day 50 (Part B),
analyses are performed using ANCOVA with baseline Ad5 titer as a
covariate. Mucosal immunogenicity analyses are conducted using the
Evaluable and PP Populations. No imputation for missing data is
performed. Endpoints analyzed are GMT and GMR for IgA antibody
level measured by ELISA. Methods used are the same as for humoral
immunogenicity analyses. Summary statistics for continuous
parameters (safety laboratory tests and vital signs) are presented
by group as follows: pre-vaccination, postvaccination, and change
from pre-vaccination to postvaccination assessment. The number and
percentage of subjects with postvaccination safety laboratory
values or vital sign values recorded as newly abnormal (ie, an
event with an increase in the toxicity grade relative to the
baseline value and with a severity grade of moderate or higher)
after study vaccination are tabulated. Shift tables that
cross-tabulate the pre-vaccination and postvaccination safety
laboratory values of each subject by severity grade are prepared.
Summaries of the number and percentage of subjects with normal,
abnormal not clinically significant, and abnormal clinically
significant ECG interpretations are presented. For shedding of the
RD-Ad5 vector, data are summarized by count and percent positive by
time point, along with median copy number. The median duration of
Ad5 shedding, interquartile range, minimum and maximum duration of
Ad5 shedding are presented for each hAdv5-SARS-CoV-2 composition
group and all hAdv5-SARS-CoV-2 composition dose groups combined.
Viral culture results for evaluation of adenovirus infection are
also listed.
[0417] These studies will show that the hAdv5-SARS-CoV-2
composition can be used to induce an anti-SARS-CoV-2 immune
response in human beings (i.e., it is an immunogenic composition),
and exhibits an acceptable safety profile. It is preferred that
that immune response be statistically significant, and even more
preferably, a protective immune response (i.e., it is a SARS-CoV-2
vaccine). In preferred embodiments, the data shows the
hAdv5-SARS-CoV-2 vaccine composition can be used to treat subjects
infected by SARS-CoV-2 (e.g., hospitalized patients).
Example 6: AdD Vectors Human Clinical Trial for SARS-CoV-2
Vaccination
[0418] In this example, the use of intranasal (i.n.) administration
of AdD vectors (i.e., replication deficient .DELTA.E1E3 adenovirus
type 5 (Ad5) viral particles encoding a pathogen antigen derived
from an infectious agent other than SARS-CoV-2, e.g. influenza such
as NasoVAX which is an AdVector (Ad5) expressing influenza
hemagglutinin (HA) antigen, described in, e.g., Ser. No. 62/830,444
filed on 6 Apr. 2019 which is incorporated herein by reference and
discloses preparation of NasoVAX) to confer prophylactic therapy
against SARS-CoV-2 is described. In embodiments, the AdD vector
induces an immune response, preferably a protective immune
response, against both SARS-CoV-2 and the pathogen associated with
the expressed exogenous antigen of the AdD vector. For example,
NasoVAX will induce an immune response against both influenza and
coronavirus including SARS-CoV-2. In this way, AdD is a dual
vaccine inducing an immune response against two respiratory
infectious agents.
[0419] To establish the immunogenic and/or protective capacity of a
composition comprising AdD vectors against SARS-CoV-2, an AdD
composition comprising AdD viral particles (vp), are administered
to human being subjects and tested for its effect on the immune
response against SARS-CoV-2 therein. To do so, a randomized,
double-blind, placebo-controlled, dose-escalation clinical trial to
evaluate the safety and immunogenicity of a AdD immunological
composition in healthy adults 18 to 49 years of age can be carried
out. Subjects are typically screened within 28 days of
randomization (Day 1).
[0420] For instance, a study can comprise two parts; part A which
evaluates safety, and part B which evaluates immunogenicity, of the
AdD composition (e.g., NasoVax). In part A, approximately 120
subjects who meet all inclusion and no exclusion criteria and
provided written informed consent are enrolled into four sequential
cohorts of 30 subjects each defined by the AdD dose
(1.times.10.sup.8, 1.times.10.sup.9, 1.times.10.sup.10, and
1.times.10.sup.11 vp), each subject being administered a single
intranasal dose in a total volume of 0.5 ml split evenly between
nostrils as a nasal spray ("placebo" subjects receive 0.5 ml of
normal saline not including AdD, the does also being split evenly
between nostrils as a nasal spray). Within each cohort (and the
sentinel group in the first dose cohort), subjects are randomized
in a 4:1:1 ratio to receive one intranasal dose of the AdD
composition (Day 1) or one intranasal dose of placebo (normal
saline) (Day 1). The AdD composition and placebo are administered
in a double-blind fashion. Reactogenicity can be ascertained by
determining counts and percentages of subjects with local events
including but not limited to nasal irritation, sneezing, nasal
congestion, cough, sore throat, change in smell, change in taste,
change in vision, eye pain, pain, tenderness, induration, erythema,
regional lymphadenopathy, and systemic events (headache, fatigue,
myalgia, nausea, vomiting, diarrhea, coughing, chills, fever) for
14 days after vaccination. Adverse Events (AEs) are determined as
counts and percentages of subjects with AEs from Day 1 to Day 57;
medically attended AEs (MAAEs), serious AEs (SAES), and new-onset
chronic illnesses (NCIs) from Day 1 to Day 181 following
administration of the AdD composition. For instance, targeted and
symptom-driven physical examinations including vital signs can be
carried out on days 4, 8, 15, 22, 29, and 57; an electrocardiogram
can be carried out on day 57; safety laboratory tests can be
carried out on days 8 and 57; and serum samples taken for
immunogenicity testing at days 8, 15, 22, 29, 57, 91, 181, and 361
(e.g., enzyme-linked immunosorbent assay (ELISA) of serum to
measure anti-SARS-CoV-2 antigen and/or anti-D antigen antibodies,
geometric mean titer (GMT) as compared to day 0 (baseline)), and/or
anti-SARS-CoV-2 and/or anti-AdD immune cellular responses (e.g., T
cell response). Responder rates are also determined as described
below (e.g., .gtoreq.four-fold rise in IgG post dose). The primary
endpoint for evaluation of the safety profile in Part A is the
number and percentage (95% confidence interval (CI)) of subjects
with solicited and unsolicited AEs recorded postvaccination. Safety
analyses is performed using the Safety Population. The number
(percentage, 95% CI) of subjects with local events and systemic
events is summarized by group, as is reactogenicity. The number
(percentage, 95% CI) of subjects with AEs from Day 1 to Day 57
(including MAAEs, NCIs, SAEs) is summarized for each Medical
Dictionary for Regulatory Activities system organ class (SOC) by
preferred term (PT) and group. The number (percentage) of subjects
with MAAEs, with NCIs, and with SAEs from Day 1 to Day 181 is
summarized in a similar fashion. The number (percentage, 95% CI) of
subjects with AEs by severity and by relationship to
investigational product (IP) is also summarized. Listings of AEs,
MAAEs, NCIs, and SAEs are provided.
[0421] In part B, the immunogenicity of the AdD composition is
determined. Following administration of the AdD composition by
intranasal spray as a single dose of 1.times.10.sup.8,
1.times.10.sup.9, 1.times.10.sup.10, and 1.times.10.sup.11 vp in a
0.5 ml volume split evenly between nostrils as a nasal spray (and
in some embodiments as two doses (3 weeks apart) of the highest
well tolerated of these doses) to subjects, the immune response can
be measured by ELISA of serum to measure anti-SARS-CoV-2 antigen
antibodies and/or anti-AdD antibodies, and the GMT, geometric mean
ratio (GMR) (the ratio of postvaccination and pre-vaccination GMTs
within the same dose group), and responder rate (.gtoreq.four-fold
rise in IgG post dose), as well as immune cellular responses (e.g.,
T cell responses), are determined. For instance, approximately 25
subjects who meet all inclusion and no exclusion criteria and
provided written informed consent are randomized in a 4:1 ratio to
receive two intranasal doses of the AdD composition at the highest
well tolerated dose from Part A or placebo 21 days apart (Days 1
and 22). The AdD composition and placebo are administered in a
double-blind fashion. Intranasal doses of the AdD composition and
placebo are administered to subjects in a sitting or reclined
position. In part B, targeted and symptom-driven physical
examination including vital signs can be carried out on days 8, 15,
22, 29, 36, 43, 50, and 57; an electrocardiogram can be carried out
on day 57; safety laboratory tests on days 8, 29, and 57; serum
samples taken for immunogenicity testing at days 8, 15, 22, 29, 57,
91, 181, and 361; and nasopharyngeal swabs collected on days 8, 15,
29, 36, 43, 50, 57, and 91. Nasopharyngeal samples collected at
Screening and on Days 29 and 57 can also be subsequently tested for
evaluation of mucosal immune response.
[0422] In some embodiments, the clinical trial can be carried out
using patients already infected by SARS-CoV-2 and time to clinical
improvement and/or recovery determined (or, in some embodiments, a
cohort of the patients tested). A primary outcome measure is Time
to Clinical Improvement (TTCI) and/or Time to Clinical Recovery
(TTCR) which are determined for up to 28 days following
administration of the AdD composition as described above. TTCI is
defined as the time (in days) from initiation of study treatment
(active or placebo) until a decline of two categories from status
at randomization on a six-category ordinal scale of clinical status
which ranges from 1 (discharged) to 6 (death). The six-category
ordinal scale is as follows: 6. Death; 5. ICU, requiring
extracorporeal membrane oxygenation (ECMO) and/or invasive
mechanical ventilation (IMV); 4. Intensive care unit
(ICU)/hospitalization, requiring non-invasive mechanical
ventilation (NIV)/high-flow nasal cannula (HFNC) therapy; 3.
Hospitalization, requiring supplemental oxygen (but not NIV/HFNC);
2. Hospitalization, not requiring supplemental oxygen; and, 1.
Hospital discharge or meet discharge criteria (discharge criteria
are defined as clinical recovery, i.e. fever, respiratory rate,
oxygen saturation return to normal, and cough relief). Secondary
outcome TTCI measures include all-cause mortality (baseline SpO2
during screening, PaO2/FiO2<300 mmHg or a respiratory rate
.gtoreq.24 breaths per min without supplemental oxygen); frequency
of respiratory progression (SPO2.ltoreq.94% on room air or
PaO2/FiO2<300 mmHg and requirement for supplemental oxygen or
more advanced ventilator support); time to defervescence (in those
with fever at enrolment); time to cough reported as mild or absent
(in those with cough at enrolment rated severe or moderate); time
to dyspnea reported as mild or absent (on a scale of severe,
moderate, mild absent, in those with dyspnoea at enrollment rated
as severe or moderate,); frequency of requirement for supplemental
oxygen or non-invasive ventilation; time to SARS-CoV-2 RT-PCR
negative in upper respiratory tract specimen; change (reduction) in
SARS-CoV-2 viral load in upper respiratory tract specimen as
assessed by area under viral load curve (e.g., as determined using
polymerase chain reaction (PCR)); frequency of requirement for
mechanical ventilation; and, frequency of serious adverse events.
TTCI is defined as the time (in hours) from initiation of study
treatment (active or placebo) until normalization of fever,
respiratory rate, and oxygen saturation, and alleviation of cough,
sustained for at least 72 hours. The primary TTCR outcome measures
include normalization and alleviation criteria;
fever--.ltoreq.36.9.degree. C. or -axilla, .ltoreq.37.2.degree. C.
oral; respiratory rate--.ltoreq.24/minute on room air; oxygen
saturation-->94% on room air; and, cough--mild or absent on a
patient reported scale of severe, moderate, mild, absent. The
secondary TTCR outcome measures are the same as the TTCI secondary
outcomes listed above.
[0423] In some embodiments, a clinical trial can be carried out on
approximately 120 subjects testing positive for SARS-CoV-2 aged
over 50 years randomized into placebo and treatment groups. The
placebo group receives 0.5 ml normal saline not including any AdD
vector, administered as a single intranasal dose split evenly
between the nostrils as a nasal spray. The treatment group is
administered 0.5 ml normal saline including any AdD vector (i.e.,
NasoVax), administered as a single intranasal dose split evenly
between the nostrils as a nasal spray. The primary efficacy
endpoints are the proportion of subjects developing acute
respiratory distress symptoms (ARDS) and maximum severity of
COVID-19 (i.e., the symptoms of SARS-CoV-2 infection) by forced
expiratory volume (FEV-1) and radiographic criteria. Secondary
endpoints include viral shedding, days on mechanical ventilation
and length of hospital stay.
[0424] Standard clinical trial design and statistical methods are
used in the analyses thereof. For instance, the sample size for
this study is selected as adequate and reasonable for an initial
review of the safety and immunogenicity profile of the AdD
composition at doses to be well tolerated, rather than for
statistical power (e.g., 120 subjects as described above). The
sample size permits initial estimates of reactogenicity. For
example, given a total of 100 subjects receiving AdD composition,
the study is designed to have an 80% probability of detecting at
least one AE that occurred at a rate of 1.6%. If no SAEs were
observed among the 100 subjects who received hAdv5-D (AdD)
composition, an approximation to the 1-sided upper bound of the 95%
confidence interval (CI) on the rate of SAE occurrence would be 3%.
Immunology analyses are conducted using the Evaluable and
Per-protocol (PP) Populations with primary conclusions drawn from
the PP Population. Analyses based on the Evaluable Population are
undertaken and presented only if >1 subject in any one group
were excluded from the PP Population. With the exception responder
analyses, as described below, no imputation for missing data is
performed. Data is transformed as appropriate prior to analysis.
Baseline was defined as the sample collected prior to AdD
composition administration on Day 1. The primary variables of
interest for assessment of humoral and cellular immune response to
SARS-CoV-2 (e.g., anti-SARS-CoV-2 and/or anti-AdD antigen IgG
titers, T cell responses) are determined. GMTs are determined at
Baseline and postvaccination on Days 8, 15, 22, 29, 57, 91, and 181
(Part A) and Days 8, 15, 22, 29, 36, 43, 50, 91, and 181 (Part B)
and summarized by dose group. Comparisons between AdD composition
doses and placebo were evaluated by analysis of covariance (ANCOVA)
with treatment as a fixed effect and baseline log-transformed level
as a covariate on, e.g., the post-baseline log-transformed level of
anti-SARS-CoV-2 IgG as a dependent variable. From these analyses,
least-square (LS) means, LS treatment differences, and 95% CIs for
the treatment differences on log-scale are obtained. The results
are transformed back to the original scale by exponentiation to
provide treatment geometric LS means, point estimates of the
geometric LS mean ratios, and 95% CI for these ratios on each study
day. A "responder" is defined as a subject with a 4-fold rise in
anti-SARS-CoV-2 and/or anti-D antigen titer from baseline on Days
8, 15, 22, 29, 57, 91, and 181 (Part A) and Days 8, 15, 22, 29, 36,
43, 50, 91, and 181 (Part B). Fold change for determination of
responder status is computed using the post-imputation values
without the +1 transformation, i.e., fold change=current imputed
value/baseline imputed value. Responder rates are tabulated by
percentages per dose group and the 95% Clopper-Pearson exact CI of
the percentage. Differences of 95% CIs are presented to compare the
response rate of each AdD composition dose group to the and placebo
group. In some embodiments, comparisons of responders in each AdD
composition dose group against the against the placebo group can
also be conducted using Fisher's exact test. To determine the
effect of pre-dose Ad5 serum antibody levels on immunogenicity of
AdD composition on Day 29 (Part A) or Day 50 (Part B), analyses are
performed using ANCOVA with baseline Ad5 titer as a covariate.
Mucosal immunogenicity analyses are conducted using the Evaluable
and PP Populations. No imputation for missing data is performed.
Endpoints analyzed are GMT and GMR for IgA antibody level measured
by ELISA. Methods used are the same as for humoral immunogenicity
analyses. Summary statistics for continuous parameters (safety
laboratory tests and vital signs) are presented by group as
follows: pre-vaccination, postvaccination, and change from
pre-vaccination to postvaccination assessment. The number and
percentage of subjects with postvaccination safety laboratory
values or vital sign values recorded as newly abnormal (ie, an
event with an increase in the toxicity grade relative to the
baseline value and with a severity grade of moderate or higher)
after study vaccination are tabulated. Shift tables that
cross-tabulate the pre-vaccination and postvaccination safety
laboratory values of each subject by severity grade are prepared.
Summaries of the number and percentage of subjects with normal,
abnormal not clinically significant, and abnormal clinically
significant ECG interpretations are presented. For shedding of the
Ad5 vector, data are summarized by count and percent positive by
time point, along with median copy number. The median duration of
Ad5 shedding, interquartile range, minimum and maximum duration of
Ad5 shedding are presented for each AdD composition group and all
immunological composition dose groups combined. Viral culture
results for evaluation of adenovirus infection are also listed.
[0425] These studies will show that the AdD composition can be used
to induce an anti-SARS-CoV-2 immune response in human beings (e.g.,
it is an immunogenic composition), and exhibits an acceptable
safety profile. It is preferred that that immune response be
statistically significant, and even more preferably, a protective
immune response (i.e., it is a SARS-CoV-2 vaccine). In preferred
embodiments, the data shows the AdD composition can be used to
treat subjects infected by SARS-CoV-2 (e.g., hospitalized
patients).
Example 7: Double-Blind, Randomized, Placebo-Controlled Study of
NasoVAX in the Prevention of Clinical Worsening in Patients with
Early Onset COVID-19
[0426] In this example, NasoVAX is used as therapy for the early
phases of infection or as a concomitant therapy with direct
antiviral agents. Pertaining to the treatment of COVID-19, NasoVAX
(and AdE) were demonstrated in preclinical mouse models to provide
protection from lethal challenge with a respiratory virus, an
effect that occurred in as little as 2 days and lasted 3 or more
weeks. See U.S. Pat. No. 9,175,310. In Example 2 above, use of AdE
(no transgene expression) was associated with down-regulation of
IL-6, IL-1a and IL-12. Those are cytokines that have been
demonstrated to mediate pulmonary interstitial inflammation in
COVID-19. The protection afforded by NasoVAX and AdE in the
pre-clinical mouse models may be attributed to the adenovirus
vector, as the vector had commensurate effects in the presence or
absence of a transgene expressing the influenza hemagglutinin (HA)
antigen. The protective effects of NasoVAX can be be viewed as a
biologic response modulating innate immunity that dampens the
excessive and pathogenic immune response to a respiratory pathogen.
This would be analogous to the use of IL-6 inhibitors Kevzara
(sarilumab) and Actemra (tocilizumab) to modulate lung inflammation
associated with COVID-19. In embodiments, an adenoviral vector
(with or without expressing a transgene from a respiratory
pathogen) when administered intranasally ameliorates COVID-19
disease symptoms.
[0427] The strength of the vector approach is that unlike other
agents that can be used to modulate lung inflammation associated
with COVID-19 (e.g., Kevzara (sarilumab) and Actemra
(tocilizumab)), NasoVAX is administered intranasally, leaving IV
access ports free for other medication; not limited to a single
cytokine; not having a hematological side-effect profile (e.g.,
neutropenia); and exhibits a prolonged duration of action, which
would be useful in very early stages in the disease process to
modulate subsequent cytokine damage. Moreover, as shown in Example
9 below, when an adenoviral vectored immunogenic composition is
administered intranasally bypasses adenovirus immunity of the
subject (e.g., those that are seropositive for the viral vector,
i.e. Ad5), allowing for repeated dosing and/or doing to adenovirus
seropositive subjects.
[0428] Thus, in some embodiments, NasoVAX could be used as therapy
for the early phases of infection or as a concomitant therapy for
COVID-19, in some embodiments in combination with direct antiviral
agents (e.g., chloroquine, azithromycin). At some juncture, the
drug substance could transition into a product in which the vector
alone (e.g., sans transgene as in AdE) is administered.
[0429] NasoVAX is prepared by isolation of bacterial colony
harboring the large recombinant adenovirus plasmid bearing the
human codon-optimized hemagglutinin cDNA from influenza
A/California/04/2009 (pAdcoCA09.HA). AdcoCA09.HA recombinant vector
was recovered from PER.C6 cells in suspension following large scale
transfection of pAdcoCA09.HA plasmid into approximately
4.times.10.sup.9 cells in a single operation using flow-cell
electroporation technology (Model STX-100, Maxcyte Inc.
Gaithersburg, Md.). At the time of harvest, the infected cells and
growth media containing any released vector were subjected to three
cycles of freeze-thaw followed by isolation and purification of the
vector by CsCl isopycnic centrifugation and dialysis against final
product formation buffer. The purified vector was amplified in
PER.C6 cells, released from the infected cell pellet by three
cycles of freeze-thaw to create an infected cell lysate that was
clarified by centrifugation and sterile filtered as the Pre-Master
Virus Seed. The NasoVAX Pre-MVS was released following testing. The
manufacture of AdcoCA09.HA includes a vector expansion step whereby
vector pre-MVS is amplified under cGMP to increase the available
seed stock for infection of the production run. The product of this
intermediate expansion step is the AdcoCA09.HA MVS. Production of
the AdcoCA09.HA MVS starts with cGMP vector expansion of the
pre-MVS followed by derivation, production, and characterization of
the MVS. Manufacturing of the drug substance includes AdcoCA09.HA
infection of PER.C6 cells in suspension followed by concentration
of the vector in the cell pellet, release of the vector from the
cell pellet, clarification of the lysate and purification of the
vector using two sequential anion exchange chromatography resins.
The product eluate is diafiltered against formulation buffer,
concentrated if necessary, and sterile filtered to create the bulk
drug substance (BDS). Final drug product (FDP) is obtained from BDS
following dilution to the appropriate strength with formulation
buffer and sterile filtration before filling into the final
container. The test product to be used in this example is NasoVAX
supplied (e.g., 1.times.10.sup.9, 10.sup.10 and/or 10.sup.11 vp) in
single-use glass syringes containing 500 .mu.L of a sterile, frozen
suspension in A195 buffer (10 mM Tris, 10 mM histidine, 5% (w/v)
sucrose, 75 mM NaCl, 1 mM MgCl.sub.2, 0.02% (w/v) polysorbate-80,
0.1 mM EDTA, 0.5% (v/v) ethanol, pH 7.4). The syringes (BD,
Accuspray.TM.) are designed to deliver 250 .mu.L of an intranasal
spray to each nostril. Alternatively, NasoVAX is supplied in 2 mL
glass vials, wherein the dose is removed to a tuberculin syringe
and affixed to a LMA MAD300 atomizer device (Teleflex, Israel)
before intranasal administration. Stability samples were packaged
in the same dosage form and container (BD Accuspray.TM.) as the
test product and tested using stability indicating assays including
physical stability of the virus particles (viral particles test,
HPLC), infectivity of the virus (infectious titer, Adenovirus
Fluorescent Focus Unit (FFU) Assay), functionality (transgene
expression) of the adenovirus vector (potency), the physical
stability of the formulation (appearance and pH), and
sterility.
[0430] In this example, a clinical trial including approximately
120 patients with early onset COVID-19 randomized 1:1 to NasoVAX
(1.times.10.sup.11 vp dose) or placebo and stratified by age is
described. Each patient will participate in the study up to
approximately 6 weeks (a 2-week Treatment Period and a 1-month
follow-up phone call). Patients are included in this study are
selected using the following non-limiting criteria: able and
willing to provide informed consent; men and women 35 years of age
and older; early onset COVID-19, defined as oral temperature
.gtoreq.38.0.degree. Celsius, onset of symptoms within 48 hours,
and confirmation of COVID-19 by a PCR-based diagnostic within 24
hours of randomization; saturated O.sub.2 (SaO.sub.2).gtoreq.96.0%
at rest for 5 minutes on two successive measurements; women of
childbearing potential (women who are not permanently sterile
[documented hysterectomy, bilateral tubal ligation, salpingectomy,
or oophorectomy] or postmenopausal [12 months with no menses
without an alternative medical cause]) exhibit negative urine
pregnancy test at screening and willingness to practice a highly
effective method of contraception that includes, but is not limited
to, abstinence, sex only with persons of the same sex, monogamous
relationship with a postmenopausal partner, monogamous relationship
with vasectomized partner, vasectomy, licensed hormonal methods,
intrauterine device, or consistent use of a barrier method (e.g.,
condom, diaphragm) with spermicide for 28 days after the last dose
of study medication; men with sexual partners of childbearing
potential have a willingness to practice a highly effective method
of contraception, as defined above, for 45 days after the last dose
of study medication; and the ability and willingness to comply with
all aspects of the study through the entire study period. Exclusion
criteria include: pregnant or lactating women; moderate or severe
shortness of breath at rest; findings on physical examination
suggesting rapid disease progression, need for immediate
hospitalization, obstructive airway diseases, including chronic
obstructive pulmonary disease (COPD) and asthma, or other
respiratory diseases that could exacerbate independent of those
caused by COVID-19; nasal conditions that might affect the
suitability of intranasal medication, such as a history of chronic
rhinitis, nasal septal defect, cleft palate, nasal polyps, or nasal
surgery other than cosmetic rhinoplasty; use of chloroquine and
hydroxychloroquine and other investigational agents for COVID-19
within the past 30 days; history of conditions associated with
immunocompromise, or treatments known to affect the immune system,
including but not limited to oral or intravenous corticosteroids,
alkylating drugs, antimetabolites, cytotoxic drugs, radiation,
immune-modulating biologics, within 30 days of screening; and, any
medical, psychiatric, or social condition or occupational or other
responsibility that in the judgment of the Investigator would
interfere with or serve as a contraindication to protocol
adherence, assessment of safety (including reactogenicity), or a
patient's ability to give informed consent.
[0431] Patients are randomized 1:1 to NasoVAX or placebo
administered as a single intranasal dose of 0.5 mL (0.25 mL each
nostril) within 24 hours of COVID-19 diagnosis. The first 20 study
participants (approximately 10 treated with NasoVAX and 10 treated
with placebo) consist of a sentinel cohort of patients ages 35 to
49 years. Patients are provided disposable finger-tip oximeters and
digital thermometers and return home for the duration of the trial.
SaO.sub.2, oral temperature, and pulse respiratory rate is
monitored remotely at rest for 2 minutes twice daily for 14 days
using mobile/smart phone pulse oximetry and web-based diaries to
record oral temperature, symptoms and concomitant medications and
telephoned daily to document clinical status and adverse events
(AEs). Patients are called approximately every 7.+-.2 days after
the last day of remote monitoring to document final outcome and
adverse events. SAEs, hospital and ICU lengths of stays, and
mortality in hospitalized patients will be documented. No in-person
visits are expected during the study.
[0432] With respect to efficacy, the Primary Objective of this
study is to assess the effectiveness of NasoVAX in preventing
clinical worsening in patients with early onset COVID-19; and the
Secondary Objectives are to assess the effectiveness of NasoVAX in
reducing rates of ICU admission and mechanical ventilation in
patients with early onset COVID-19 and the severity of COVID-19 in
patients with early onset COVID-19 who require hospitalization. The
primary endpoint is the proportion of patients with clinical
worsening, defined as a 4% decrease in mean SaO.sub.2 to a level of
94% or less by mobile pulse oximetry at any measurement during home
follow-up, or hospitalization. In ambulatory patients, secondary
efficacy endpoints include severity of COVID-19, assessed by
maximum decrease in SaO.sub.2 and spontaneous ventilation rate by
outpatient pulse oximetry during home follow-up and the proportion
of patients requiring mechanical ventilation. In hospitalized
patients, the secondary efficacy endpoints include ventilator-free
days, defined as one point (day) for each day between the dose of
study medication on Day 1 and Day 30 (relative to the first dose of
study drug) that a patient is both alive and free of mechanical
ventilation and the ratio of arterial oxygen partial pressure to
fractional inspired oxygen (P/F ratio).
[0433] With respect to safety, the Primary Objective is to assess
the safety and tolerability of NasoVAX in preventing clinical
worsening in patients with early onset COVID-19. These include
incidence and severity of adverse events (AEs), mortality, hospital
length of stay, and ICU length of stay. Safety endpoints are
categorized separately between AEs reported at home vs. those
reported during hospitalization for medical care.
[0434] Statistical methods include the Power and Sample Size
Assumptions that 10% of patients receiving NasoVAX develop clinical
worsening vs. 29% receiving placebo, 60 patients per treatment arm
provides 77% power at a one-sided a of 0.05 to achieve statistical
significance on the primary efficacy variable. Population
definitions include: "Safety Analysis Set": all patients who
receive any study medication; "Intent to treat" (ITT): all
randomized patients who receive any amount of study medication,
have a baseline and at least one post-baseline SaO.sub.2
measurement. Subjects are analyzed according to the treatment that
they receive; and, "Per Protocol" (PP): all randomized patients who
receive any amount of study medication according to the correct
treatment assignment and who have twice daily results from
SaO.sub.2 measurements through Day 14 or hospitalization. Baseline
is defined as data collected closest to randomization prior to any
study medication dosing. All analyses and summary statistics are
presented by treatment group (NasoVAX, placebo). Descriptive
statistics, including the numbers and percentages for categorical
variables and the numbers, means, standard deviations, medians,
minimums and maximums for continuous variables are provided by
treatment. Patients are randomized 1:1 to NasoVAX or placebo and
stratified by age group (35-49 years vs. 50 years and older). To
assure a 1:1 distribution of NasoVax and placebo (10 patients each
of 20 patients) in the sentinel cohort, randomization in this group
are not stratified. For the Efficacy Analyses, descriptive
statistics are used to evaluate differences in demographic and
baseline characteristics. For the primary analysis, proportions of
patients with clinical worsening, defined as a 4% decrease in mean
SaO.sub.2 to a level of 94% or less by mobile pulse oximetry at any
measurement during home follow-up, or hospitalization, are compared
between NasoVAX and placebo groups using the Cochrane Mantel
Haenszel test at a 0.05% one-sided level of significance. The same
approach is applied for secondary or exploratory endpoints that are
categorical in nature. Subjects who discontinue prematurely or have
missing data are considered non-responders for that endpoint.
Sensitivity analyses are performed to assess the effect of site on
the response to study medication. Linear and logistic regression
are employed to examine the effects of baseline factors, such as
age, sex, medications and medical co-morbidities on response.
Quantitative safety data are summarized using descriptive
statistics and frequency distributions. All summaries are presented
by treatment arms. AEs are coded using Medical Dictionary for
Regulatory Activities)(MedDRA.RTM.), Concomitant medications are
coded using World Health Organization (WHO) drug dictionary.
Changes from baseline in Severity of COVID-19, assessed by maximum
decrease in SaO.sub.2 and spontaneous ventilation rate by
outpatient pulse oximetry during home follow-up, are analyzed using
a mixed model for repeated measures (MMRM) model. The model will
include the fixed effects of treatment, stratification factor,
week, and treatment-by-visit interaction as well as the continuous,
covariate of baseline level. The model will employ an unstructured
within patient covariance matrix and a restricted maximum
likelihood (ReML) estimation method. Ventilator-free days are
analyzed using a t-test or Mann-Whitney for continuous data. A
Kaplan-Meier model is developed to compare changes between
treatment groups in SaO.sub.2 over time. No multiplicity
adjustments are made for secondary or exploratory endpoints.
[0435] These studies will show that the NasoVAX can be used to
induce an anti-SARS-CoV-2 immune response in human beings (e.g., it
is an immunogenic composition), and exhibits an acceptable safety
profile. The data will also show that NasoVAX is effective in
reducing rates of ICU admission and mechanical ventilation in
patients with early onset COVID-19 and the severity of COVID-19 in
patients with early onset COVID-19 who require hospitalization. In
some embodiments, a decrease in expression of inflammatory
cytokines such as IL-1.alpha., IL-5, IL-6, IL-12, IL-17, MCP-1,
tumor necrosis factor alpha (TNF-.alpha.), granulocyte macrophage
colony stimulating factor (GM-CSF), and/or RANTES (CCL5) (see,
e.g., Example 2) following administration of NasoVAX to subjects
can occur, and can in some embodiments be used to diagnose
COVID-19, and/or predict recovery therefrom and used to adjust
treatment protocols (e.g., non-NasoVAX treatments) accordingly. In
some embodiments, an increase in MCP1 and/or RANTES shortly after
administration of NasoVAX, can be used to predict (e.g., as a
marker) recovery from COVID-19 and amelioration of symptoms. It is
preferred that that immune response be statistically significant,
and even more preferably, a protective immune response (i.e., it is
a SARS-CoV-2 vaccine). In preferred embodiments, the data shows
that NasoVAX can be used to treat subjects infected by SARS-CoV-2
(e.g., hospitalized patients).
Example 8. NasoVAX Stability at Room Temperature
[0436] This example describes the long-term stability of NasoVAX in
a liquid formulation at room temperature. Long-term stability at
room temperature is desire feature of vaccines that can be used in
situations in which refrigeration or other means for stabilizing a
formulation may not be available. This would be important in
epidemic or pandemic situations during which vaccines need to be
shipped to remote areas that may lack the equipment to maintain
formulations at a cooler temperature, or shipped directly to
end-users, such as individual self-isolating at home or in
quarantine. As shown in Tables 9 and 10 below, low dose
(2.times.10.sup.9 vp/mL dose) and high dose (2.times.10.sup.11
vp/mL dose) formulations, respectively, were prepared and
maintained at room temperature in glass vials for one, three and
six months. Viability of the NasoVAX vectors was determined using
the Adenovirus Fluorescent Focus Unit (FFU) assay. Briefly, the FFU
assay is carried out by infecting cell monolayers with the
appropriate NasoVAX dilution and incubated for 24-48 hours. The
cells were then washed, inspected, fixed (e.g., ice-cold 90%
methanol for four minutes), and washed again. Anti-Ad5 antibody was
then added at various dilutions (antibody omitted in control
samples), followed by a detection agent (e.g., NCL-Adeno
(Novocastra, Newcastle, UK)) under appropriate conditions (e.g.,
ten minutes at room temperature with shaking). The cells are then
washed, and the total number of infectious particles determined
(e.g., by digital light scattering (DLS)). As shown in Tables 15
and 16, the low-dose and high-dose NasoVAX formulations were stable
for at least three months at room temperature.
[0437] This study shows an adenoviral vectored vaccine composition
(e.g., NasoVAX) is stable for about 3 months at an ambient
temperature, such as room temperature (e.g., 15 to 30.degree. C.,
preferably 20-25.degree. C.). In embodiments, an adenoviral
vectored vaccine composition can be stored, or shipped, without the
need for refrigeration or specific storage conditions. In certain
embodiments, the present intranasal adenoviral vectored vaccine is
configured to induce an immune response against SARS-CoV-2 virus (a
pandemic coronavirus strain) infection and/or to ameliorate
COVID-19 disease symptoms and may be shipped directly to the user
for intranasal administration.

Example 9: NasoVAX Shedding and Anti-NasoVAX Vector Antibodies
[0438] NasoVAX was previously evaluated in a Phase 2a, randomized,
double-blind, placebo-controlled trial to evaluate the safety and
immunogenicity of NasoVAX (monovalent Adco.CA.HA), in healthy
adults 18 to 49 years of age. The subjects were randomized and
given a single dose of 1.times.10.sup.9, 1.times.10.sup.10, and
1.times.10.sup.11 viral particles (vp) or saline placebo, all given
as a 0.5 mL dose split approximately as 0.25 ml nasal spray in each
nostril. The protocol was described in U.S. Ser. No. 62/830,442
filed 6 Apr. 2019.
[0439] A secondary objective of that study was to evaluate the
immune response against the adenoviral vector (Ad5) for subjects
that were seropositive for Ad5 (as compared to subjects that were
seronegative) at the time of administration of NasoVAX. At four,
eight and 15 days post-dose, nasopharyngeal swab samples were
collected from each subject and the concentration of the Ad5 vector
shed by each quantified by polymerase chain reaction (PCR) assay.
As shown in FIG. 25, dose-dependent shedding of NasoVAX vector was
detected until day 8 post-dose and was not detected at day 15. No
replication-competent virus was detected.
[0440] FIG. 25 also illustrates the GMR of antibodies against the
Ad5 vector component of NasoVAX following administration of a
single intranasal dose of 10.sup.9 vp, 10.sup.10 vp, or 10.sup.11
vp of NasoVAX. As shown therein, administration of the highest dose
(10.sup.11 vp) surprisingly only resulted in about a 2.3-fold
induction of anti-Ad5 vector antibodies in subjects as compared to
control. This is an important finding as it indicates the
intranasal route of administration can be used for repeated dosing
of NasoVAX, or potentially other adenoviral vectored immunogenic
compositions, including Ad5-based vectors.
[0441] FIG. 26 shows the effect of pre-existing anti-Ad5 immunity
on Ad5 serostatus following administration of a single intranasal
dose (10.sup.11 vp) of NasoVAX to subjects. As shown therein,
pre-existing anti-Ad5 immunity ("Ad5 Seropositive" (median titer
being 22-fold above the lower limit of quantitation ("LLOQ")) had
little effect on humoral (HAI), microneutralization (MN), mucosal
(IgA), or cellular (ELISpot) anti-Ad5 immunity following
administration of the intranasal dose of NasoVAX. This is another
important finding as it indicates that NasoVAX can be administered
intranasally even to a subject with pre-existing immunity to Ad5.
In embodiments, the present intranasal adenoviral vectored vaccine
can be administered repeatedly (e.g., as a seasonal vaccine
administered about once every 11-14 months) without inducing a
significant immune response against the viral vector.
Example 10: Combination of rdAd Anti-SARS-CoV-2 Vectors Human
Clinical Trial as SARS-CoV-2 Vaccine
[0442] In this example, intranasal (i.n.) administration of a
combination of rdAd anti-SARS-CoV-2 vectors (e.g., a "combined
SARS-CoV-2 composition") to confer prophylactic therapy against
SARS-CoV-2 is described. To establish the immunogenic and/or
protective capacity of such immunogenic composition(s), a
composition comprising AdE is first administered to a human being,
followed seven days later by administration of a composition
comprising hAd5-SARS-CoV-2, which is followed by testing of the
effect of this combination on the immune response against
SARS-CoV-2 in the human being(s). The sequential administration of
the composition AdE and then the composition comprising
hAd5-SARS-CoV-2 is referred to herein as the "combined SARS-CoV-2
composition". To do so, a randomized, double-blind,
placebo-controlled, dose-escalation clinical trial to evaluate the
safety and immunogenicity of combined SARS-CoV-2 composition in
healthy adults 18 to 49 years of age can be carried out. Subjects
are typically screened within 28 days of randomization (Day 1).
[0443] For instance, a study can comprise two parts; part A which
evaluates safety, and part B which evaluates immunogenicity, of the
combined SARS-CoV-2 composition. In part A, approximately 120
subjects who meet all inclusion and no exclusion criteria and
provided written informed consent are enrolled into four sequential
cohorts of 30 subjects each defined by the combined SARS-CoV-2
composition doses (1.times.10.sup.8, 1.times.10.sup.9,
1.times.10.sup.10, and 1.times.10.sup.11 vp in each dose). Within
each cohort (and the sentinel group in the first dose cohort),
subjects are randomized in a 4:1:1 ratio to receive one intranasal
dose of the combined SARS-CoV-2 composition (AdE composition on day
1 followed by hAd5-SARS-CoV-2 composition on day 7) or intranasal
doses of placebo (normal saline) (on days 1 and 7). The combined
SARS-CoV-2 composition and placebo are administered in a
double-blind fashion. Reactogenicity is ascertained by determining
counts and percentages of subjects with local events including but
not limited to nasal irritation, sneezing, nasal congestion, cough,
sore throat, change in smell, change in taste, change in vision,
eye pain, pain, tenderness, induration, erythema, regional
lymphadenopathy, and systemic events (headache, fatigue, myalgia,
nausea, vomiting, diarrhea, coughing, chills, fever) for 14 days
after vaccination. Adverse Events (AEs) are determined as counts
and percentages of subjects with AEs from Day 1 to Day 57;
medically attended AEs (MAAEs), serious AEs (SAES), and new-onset
chronic illnesses (NCIs) from Day 1 to Day 181 following
administration of the combined SARS-CoV-2 composition or placebo.
For instance, targeted and symptom-driven physical examinations
including vital signs can be carried out on days 4, 8, 15, 22, 29,
and 57; an electrocardiogram can be carried out on day 57; safety
laboratory tests can be carried out on days 8 and 57; and serum
samples taken for immunogenicity testing at days 8, 15, 22, 29, 57,
91, 181, and 361 (e.g., enzyme-linked immunosorbent assay (ELISA)
of serum to measure anti-SARS-CoV-2 antigen antibodies, geometric
mean titer (GMT) as compared to day 0 (baseline)), and/or
anti-SARS-CoV-2 immune cellular responses (e.g., T cell response).
Responder rates are also determined as described below (e.g.,
.gtoreq.four-fold rise in IgG post dose). The primary endpoint for
evaluation of the safety profile in Part A is the number and
percentage (95% confidence interval (CI)) of subjects with
solicited and unsolicited AEs recorded postvaccination. Safety
analyses is performed using the Safety Population. The number
(percentage, 95% CI) of subjects with local events and systemic
events is summarized by group, as is reactogenicity. The number
(percentage, 95% CI) of subjects with AEs from Day 1 to Day 57
(including MAAEs, NCIs, SAEs) is summarized for each Medical
Dictionary for Regulatory Activities system organ class (SOC) by
preferred term (PT) and group. The number (percentage) of subjects
with MAAEs, with NCIs, and with SAEs from Day 1 to Day 181 is
summarized in a similar fashion. The number (percentage, 95% CI) of
subjects with AEs by severity and by relationship to
investigational product (IP) is also summarized. Listings of AEs,
MAAEs, NCIs, and SAEs are provided.
[0444] In part B, the immunogenicity of the combined SARS-CoV-2
composition is determined. Following administration of the combined
SARS-CoV-2 composition by intranasal spray as a single dose of
1.times.10.sup.8, 1.times.10.sup.9, 1.times.10.sup.10, and
1.times.10.sup.11 vp (i.e., combined SARS-CoV-2 composition (AdE
composition on day 1 followed by hAd5-SARS-CoV-2 composition on day
7) of the highest well tolerated of these doses to subjects, the
immune response can be measured by ELISA of serum to measure
anti-SARS-CoV-2 antigen antibodies, and the GMT, geometric mean
ratio (GMR) (the ratio of postvaccination and pre-vaccination GMTs
within the same dose group), and responder rate (.gtoreq.four-fold
rise in IgG post dose), as well as immune cellular responses (e.g.,
T cell responses). For instance, approximately 25 subjects who meet
all inclusion and no exclusion criteria and provided written
informed consent are randomized in a 4:1 ratio to receive two
intranasal doses of the combined SARS-CoV-2 composition at the
highest well tolerated dose from Part A or placebo 21 days apart
(Days 1 and 22). The combined SARS-CoV-2 composition and placebo
are administered in a double-blind fashion. Intranasal doses of the
combined SARS-CoV-2 composition immunogenic composition and placebo
are administered to subjects in a sitting or reclined position. In
part B, targeted and symptom-driven physical examination including
vital signs can be carried out on days 8, 15, 22, 29, 36, 43, 50,
and 57; an electrocardiogram can be carried out on day 57; safety
laboratory tests on days 8, 29, and 57; serum samples taken for
immunogenicity testing at days 8, 15, 22, 29, 57, 91, 181, and 361;
and nasopharyngeal swabs collected on days 8, 15, 29, 36, 43, 50,
57, and 91. Nasopharyngeal samples collected at screening and on
Days 29 and 57 can also be subsequently tested for evaluation of
mucosal immune response.
[0445] In some embodiments, the clinical trial can be carried out
using patients already infected by SARS-CoV-2 and time to clinical
improvement and/or recovery determined (or, in some embodiments, a
cohort of the patients tested). A primary outcome measure is Time
to Clinical Improvement (TTCI) and/or Time to Clinical Recovery
(TTCR) which are determined for up to 28 days following
administration of the combined SARS-CoV-2 composition as described
above. TTCI is defined as the time (in days) from initiation of
study treatment (active or placebo) until a decline of two
categories from status at randomization on a six-category ordinal
scale of clinical status which ranges from 1 (discharged) to 6
(death). The six-category ordinal scale is as follows: 6. Death; 5.
ICU, requiring extracorporeal membrane oxygenation (ECMO) and/or
invasive mechanical ventilation (IMV); 4. Intensive care unit
(ICU)/hospitalization, requiring non-invasive mechanical
ventilation (NIV)/high-flow nasal cannula (HFNC) therapy; 3.
Hospitalization, requiring supplemental oxygen (but not NIV/HFNC);
2. Hospitalization, not requiring supplemental oxygen; and, 1.
Hospital discharge or meet discharge criteria (discharge criteria
are defined as clinical recovery, i.e. fever, respiratory rate,
oxygen saturation return to normal, and cough relief). Secondary
outcome TTCI measures include all cause mortality (baseline SpO2
during screening, PaO.sub.2/FiO.sub.2<300 mmHg or a respiratory
rate .gtoreq.24 breaths per min without supplemental oxygen);
frequency of respiratory progression (SPO2.ltoreq.94% on room air
or PaO2/FiO2<300 mmHg and requirement for supplemental oxygen or
more advanced ventilator support); time to defervescence (in those
with fever at enrolment); time to cough reported as mild or absent
(in those with cough at enrollment rated severe or moderate); time
to dyspnea reported as mild or absent (on a scale of severe,
moderate, mild absent, in those with dyspnoea at enrolment rated as
severe or moderate,); frequency of requirement for supplemental
oxygen or non-invasive ventilation; time to 2019-nCoV RT-PCR
negative in in throat swab, sputum, lower respiratory tract
specimen, and/or upper respiratory tract specimen; change
(reduction) in SARS-CoV-2 viral load in throat swab, sputum, lower
respiratory tract specimen, and/or upper respiratory tract
specimen; change (reduction) in 2019-nCoV viral load in in throat
swab, sputum, lower respiratory tract specimen, and/or upper
respiratory tract specimen; change (reduction) in SARS-CoV-2 viral
load in throat swab, sputum, lower respiratory tract specimen,
and/or upper respiratory tract specimen as assessed by area under
viral load curve (e.g., as determined using polymerase chain
reaction (PCR)); frequency of requirement for mechanical
ventilation; and, frequency of serious adverse events. TTCI is
defined as the time (in hours) from initiation of study treatment
(active or placebo) until normalization of fever, respiratory rate,
and oxygen saturation, and alleviation of cough, sustained for at
least 72 hours. The primary TTCR outcome measures include
normalization and alleviation criteria; fever--.ltoreq.36.9.degree.
C. or -axilla, .ltoreq.37.2.degree. C. oral; respiratory
rate--.ltoreq.24/minute on room air; oxygen saturation-->94% on
room air; and, cough--mild or absent on a patient reported scale of
severe, moderate, mild, absent. The secondary TTCR outcome measures
are the same as the TTCI secondary outcomes listed above.
[0446] Standard clinical trial design and statistical methods are
used in the analyses thereof. For instance, the sample size for
this study is selected as adequate and reasonable for an initial
review of the safety and immunogenicity profile of the combined
SARS-CoV-2 composition at doses to be well tolerated, rather than
for statistical power (e.g., 120 subjects as described above). The
sample size permits initial estimates of reactogenicity. For
example, given a total of 100 subjects receiving the combined
SARS-CoV-2 composition, the study is designed to have an 80%
probability of detecting at least one AE that occurred at a rate of
1.6%. If no SAEs were observed among the 100 subjects who received
hAdv5-SARS-CoV-2 composition, an approximation to the 1-sided upper
bound of the 95% confidence interval (CI) on the rate of SAE
occurrence would be 3%. Immunology analyses are conducted using the
Evaluable and Per-protocol (PP) Populations with primary
conclusions drawn from the PP Population. Analyses based on the
Evaluable Population are undertaken and presented only if >1
subject in any one group were excluded from the PP Population. With
the exception responder analyses, as described below, no imputation
for missing data is performed. Data are transformed as appropriate
prior to analysis. Baseline is defined as the sample collected
prior to combined SARS-CoV-2 composition administration on days 1
(for the AdE composition) and 7 (for the hAdv5-SARS-CoV-2
composition). The primary variables of interest for assessment of
humoral and cellular immune response to SARS-CoV-2 (e.g.,
anti-SARS-CoV-2 antigen IgG titers, T cell responses) are
determined. GMTs are determined at Baseline and postvaccination on
Days 8, 15, 22, 29, 57, 91, and 181 (Part A) and Days 8, 15, 22,
29, 36, 43, 50, 91, and 181 (Part B) and summarized by dose group.
Comparisons between combined SARS-CoV-2 composition doses and
placebo are evaluated by analysis of covariance (ANCOVA) with
treatment as a fixed effect and baseline log-transformed level as a
covariate on, e.g., the post-baseline log-transformed level of
anti-SARS-CoV-2 IgG as a dependent variable. From these analyses,
least-square (LS) means, LS treatment differences, and 95% CIs for
the treatment differences on log-scale are obtained. The results
are transformed back to the original scale by exponentiation to
provide treatment geometric LS means, point estimates of the
geometric LS mean ratios, and 95% CI for these ratios on each study
day. A "responder" is defined as a subject with a 4-fold rise in
anti-SARS-CoV-2 antigen titer from baseline on Days 8, 15, 22, 29,
57, 91, and 181 (Part A) and Days 8, 15, 22, 29, 36, 43, 50, 91,
and 181 (Part B). Fold change for determination of responder status
is computed using the post-imputation values without the +1
transformation, i.e., fold change=current imputed value/baseline
imputed value. Responder rates are tabulated by percentages per
dose group and the 95% Clopper-Pearson exact CI of the percentage.
Differences of 95% CIs are presented to compare the response rate
of each combined SARS-CoV2 composition dose group to the and
placebo group. In some embodiments, comparisons of responders in
each combined SARS-CoV-2 composition dose group against the against
the placebo group can also be conducted using Fisher's exact test.
To determine the effect of pre-dose Ad5 serum antibody levels on
immunogenicity of combined SARS-CoV-2 composition on Day 29 (Part
A) or Day 50 (Part B), analyses are performed using ANCOVA with
baseline Ad5 titer as a covariate. Mucosal immunogenicity analyses
are conducted using the Evaluable and PP Populations. No imputation
for missing data is performed. Endpoints analyzed are GMT and GMR
for IgA antibody level measured by ELISA. Methods used are the same
as for humoral immunogenicity analyses. Summary statistics for
continuous parameters (safety laboratory tests and vital signs) are
presented by group as follows: pre-vaccination, postvaccination,
and change from pre-vaccination to postvaccination assessment. The
number and percentage of subjects with postvaccination safety
laboratory values or vital sign values recorded as newly abnormal
(ie, an event with an increase in the toxicity grade relative to
the baseline value and with a severity grade of moderate or higher)
after study vaccination are tabulated. Shift tables that
cross-tabulate the pre-vaccination and postvaccination safety
laboratory values of each subject by severity grade are prepared.
Summaries of the number and percentage of subjects with normal,
abnormal not clinically significant, and abnormal clinically
significant ECG interpretations are presented. For shedding of the
Ad5 vector, data are summarized by count and percent positive by
time point, along with median copy number. The median duration of
Ad5 shedding, interquartile range, minimum and maximum duration of
Ad5 shedding are presented for each combined SARS-CoV-2 composition
group and all immunogenic composition dose groups combined. Viral
culture results for evaluation of adenovirus infection are also
listed.
[0447] These studies will show that the combined SARS-CoV-2
composition can be used to induce an anti-SARS-CoV-2 immune
response in human beings (e.g., it is an immunogenic composition),
and with an acceptable safety profile. It is preferred that that
immune response be statistically significant, and even more
preferably, a protective immune response (i.e., it is a SARS-CoV-2
vaccine). In preferred embodiments, the data shows the combined
SARS-CoV-2 composition can be used to treat subjects infected by
SARS-CoV-2 (e.g., hospitalized patients).
Example 11: Anti-SARS-CoV-2 Human Clinical Trial Using Cytokine
Inhibition
[0448] As shown in Example 2, administration of AdE to mice was
shown to decrease the expression of certain cytokines known to be
involved in the progression and symptoms of infectious diseases
caused by viruses such as influenza. For instance, it was shown
that non-infected mice (by influenza), 25 days after administration
of AdE, exhibited an increase in expression of monocyte
chemoattractant protein (MCP-1 (CCL2)), interferon gamma
(IFN-.gamma.), and RANTES (CCL5). At 28 days post-administration of
AdE, such non-infected mice exhibited increased expression of MCP-1
and IFN-.gamma. but also a decrease in IL-12 expression. Mice
challenged with influenza at day 3 post-administration of AdE, mice
were found to exhibit decreased expression of IL-1.alpha., IL-6,
IL-12, MCP-1, tumor necrosis factor alpha (TNF-.alpha.),
granulocyte macrophage colony stimulating factor (GM-CSF), and
RANTES. At day six (6) post-administration of AdE, the infected
mice exhibited decreased expression of IL-5, IL-6, IL-12, IL-17,
MCP-1 and GM-CSF, and increased expression of macrophage
inflammatory protein 1 alpha (MIP-1.alpha. (CCL3)) and RANTES
(CCL5). These results are consistent with the development of a
"cytokine storm" during infection by SARS-CoV-2. In some
embodiments, then, to prevent and/or treat SARS-CoV-2 infection by,
for instance, inhibiting the development of or suppressing a
cytokine storm, aSARS-CoV-2 immunogenic composition is administered
to a human being with one or more anti-cytokine reagent(s) (e.g.,
one or more anti-IL-1a reagent(s), one or more anti-IL5 reagent(s),
one or more anti-IL-6 reagent(s), one or more anti-IL-12
reagent(s), one or more anti-IL-17 reagent(s), one or more
anti-MCP-1 reagent(s), one or more anti-TNF-.alpha. reagent(s), one
or more anti-GM-CSF reagent(s), and/or one or more anti-RANTES
reagent(s). In some embodiments, the one or more anti-cytokine
reagents would not include one or more anti-MIP.alpha. reagent(s)
and/or one or more anti-RANTES reagent(s). Exemplary anti-cytokine
reagents that can be used as described herein can include, for
example, any of those shown in Table 10.
[0449] Such anti-cytokine reagents are administered with the
SARS-CoV-2 immunogenic composition at the same time (i.e.,
simultaneously), or essentially the same time, by a suitable route
appropriate for each reagent (e.g., intranasal administration of
the SARS-CoV-2 immunogenic composition and subcutaneous injection
for the anti-cytokine reagent(s) in effective amounts. In some
embodiments, the one or more anti-cytokine reagent(s) are
co-administered with the SARS-CoV-2 composition and, in some
embodiments, the one or more anti-cytokine reagents are
subsequently administered as the sole active agents. These studies
will show that the combination of SARS-CoV-2 composition(s) and one
or more anti-cytokine reagent(s) are useful for inducing an
anti-SARS-CoV-2 immune response in human beings (e.g., it is an
immunogenic composition), with an acceptable safety profile, and
with alleviation of symptoms related to the deleterious effects of
cytokines experienced by some patients (e.g., the aforementioned
cytokine storm). It is preferred that that immune response be
statistically significant, and even more preferably, that it is a
protective and/or curative immune response (i.e., it is a
SARS-CoV-2 vaccine). In preferred embodiments, the data shows the
combination of SARS-CoV-2 composition(s) and one or more
anti-cytokine reagent(s) can be used to treat subjects infected by
SARS-CoV-2 (e.g., hospitalized patients).
Example 12. Animal Study Dosing Strategies
[0450] In some embodiments, one or more anti-SARS-CoV-2 vectors
and/or combination(s) of anti-SARS-CoV-2 vectors (i.e., "SARS-CoV-2
vaccine") are administered to animals in various dosages to assess
pre-clinical validation of the same. In some embodiments, the
mechanisms of vaccine-induced protection in animals are determined.
In some embodiments, the mechanisms of vaccine-induced protection
in animals with pre-existing immunity to the more common
circulating coronaviruses (as is the case for most humans) are
determined. These studies provide: (i) an assessment of SARS-CoV-2
vaccine-induced pulmonary inflammation; (ii) SARS-CoV-2 vaccine Ab
titers with isotype and breadth of reactivity to day 28; (iii)
anti-SARS-CoV-2 antibody (Ab) neutralization titers to day 28
post-administration; and, (iv) identification of optimal SARS-CoV-2
vaccine dose/administration schedule.
[0451] In some embodiments, the immunity of the animals can be
studied using the flow cytometric techniques described by Yu, et
al. (PLOS ONE DOI:10.1371/journal.pone.0150606 Mar. 3, 2016) which
has been shown to be useful for accurately quantifying eleven
distinct immune cell types, including T cells, B cells, natural
killer (NK) cells, neutrophils, eosinophils, inflammatory
monocytes, resident monocytes, macrophages (e.g., tissue specific
macrophages, resident/interstitial macrophages, alveolar
macrophages, microglia), mast cells, basophils, and/or plasmacytoid
DCs, and/or to perform detailed phenotyping of specific cell types.
In some embodiments, for instance, a comparison of SSC vs. MHC
Class II expression can be used to separate NK cells and monocytes
from mature myeloid cells; and/or, a comparison of CD64 vs. CD24
expression can be used to distinguish macrophages from dendritic
cells as can CD11c vs. MHC class two expression (although the
former may be more accurate). Other markers may also be studied as
is known in the art (e.g., any one or more of CD11b, CD14, CD24,
CD68, CD103, CD169, CD206, CX.sub.3CR1, CCR2, F4/80, Ly6C, and/or
MerTK). In some embodiments, anti-SARS-2-CoV-2 specific antibody
titers in the lung airways and serum are determined (e.g., using
bead arrays); inflammatory cell infiltrate into the lungs is
measured (e.g., using flow cytometry); anti-SARS-CoV-2
neutralization titers are determined (e.g., using SARS-2
microneutralization assays); local and systemic cytokine levels are
assessed; the number and functional attributes of anti-SARS-2
specific B cells (e.g., and subsets), T cells (e.g., (using ICCS or
cytokine ELISPOTs) and plasma cells (e.g., using antibody ELISPOT)
from early (7-14 days) to memory (1-4 months) timepoints following
vaccination in naive mice and those with pre-existing immunity to
related endemic coronaviruses are determined. Other types of
analyses may also be used as is known in the art, or would
otherwise be understood by those of ordinary skill in the art to be
applicable.
[0452] In some embodiments, the mechanisms of vaccine-induced
protection in animals are determined studying animals to which the
SARS-CoV-2 vaccine is administered following the dosing scheme
shown in Table 17.

using the optimal dosing and administration schedule determined by
the scheme presented in Table 18. Data is collected at four
timepoints (e.g., n=7/group/timepoint/functional assay, timepoints
between 0-120 days). SARS-CoV-2 vaccine-induced pulmonary
inflammation and Ab responses are measured to day 28,
anti-SARS-CoV-2 Ab titers with isotype and breadth of reactivity
are determined to day 120, anti-SARS-CoV-2 Ab neutralization titers

pre-existing immunity to endemic .beta.-coronavirus affects vaccine
responses to SARS2. In this experiment (table 3), impact of
pre-existing anti-coronavirus Spike protein memory B cells against
endemic .beta.-coronaviruses is assessed. Inbred mice (BALB/c or
B6) are vaccinated with recombinant OC43 or HKU1 Spike protein
using two different adjuvants (CFA or alum) to establish a memory B
cell response to the endemic coronavirus Spike protein (i.e.,
"memory mice"). Immunized mice and control naive mice then receive
the optimal SARS-CoV-2 vaccine(s). Pulmonary inflammation,
anti-SARS-CoV-2 Ab and B cell responses, anti-SARS-CoV-2 Ab quality
are assessed in the memory mice. Additional details regarding the
administration scheme is provided in Table 19.

Example 13A. Preparation of the Adenoviral Vectors (S1 and RBD) for
Preclinical Testing
[0455] Vaccine candidates utilized in example 13A to 18 were
prepared using a replication-deficient, E1- and E3-deleted
adenovirus type 5 vector platform (Tang et al 2009) to express the
human codon-optimized gene for the S1 domain (residues 16 to 685)
or RBD domain (residues 302 to 543) of SARS-CoV-2 spike protein
(accession number QHD43416.1). The Ad5-vectored S1 and RBD
transgenes included a human tissue plasminogen activator leader
sequence and were expressed under the control of the
cytomegalovirus immediate early promoter/enhancer, SEQ ID NO: 13
and SEQ ID NO: 15, respectively. Initial seed stocks were obtained
from a large-scale transfection of recombinant vector plasmid into
E1-complementing PER.C6 cells using a scalable transfection system
(Maxcyte STX-100). Cell transfection was performed by a static
electroporation using the CL1.1 Processing Assembly procedure (Li L
H, Shivakumar R, Feller S, Allen C, Weiss J M, Dzekunov S, Singh V,
Holaday J, Fratantoni J, Liu L N. Highly efficient, large volume
flow electroporation. Technol Cancer Res Treat. 2002 October;
1(5):341-50.). Following further expansion, infected cells were
collected 70 hours post-infection and virus was released from
pelleted cells by freeze-thaw cycles. Resulting cell lysate was
clarified by centrifugation, then filtered using a 0.22 .mu.m
cutoff. RBD and S1 Ad5 vectors were purified over a CsCl gradient,
dialyzed against a formulation buffer (A195) containing 10 mM Tris
at a pH of 7.4, 75 mM NaCl, 1 mM MgCl.sub.2, 10 mM histidine, 5%
(wt/vol) sucrose, 0.02% polysorbate-80 (wt/vol), 0.1 mM EDTA, and
0.5% (vol/vol) ethanol and were then frozen and stored at
-65.degree. C. To confirm that the S1 and RBD transgenes were
expressed and antigenically intact, PerC6 cells were infected with
S1 vector or RBD vectors before intracellular staining using two
different neutralizing monoclonal antibodies against SARS-CoV-2 S1
(SinoBiologicals Cat: 40591-MM43) and SARS-CoV-2 RBD
(SinoBiologicals, Cat: 40592-MM57) and analysis by flow cytometry
(FIG. 93).
Example 13B. Intranasal Administration of Ads Vector Expressing RDB
Domain in C57BL/6 Mice
[0456] Replication-deficient Ad5 vector expressing the RBD domain
from the spike antigen of SARS-CoV-2 (SEQ ID NO: 15) was
administered intranasally to C57BL/6 mice to evaluate the induction
of systemic and mucosal immunity against SARS-CoV-2. C57BL/6 mice
received one or two intranasal administration of the Ad5 vector at
three different doses in a volume of 50 .mu.l as indicated in table
18. High dose was 6.7E+09 ifu/ml (3.35E+08 ifu in 50 mid-dose
1.2E+09 ifu/ml (6E+07 ifu in 50 .mu.L) and Low dose 1.2E+08 ifu/ml
(6E+06 ifu in 50 .mu.L) in A195 buffer. The control group received
an intranasal administration of 50 .mu.l of the A195 buffer alone.
At day 7, day 14, day 21 or day 28 post-vaccine administration,
sera, bronchoalveolar lavages (BAL) and tissues including lungs,
mediastinal lymph nodes and spleens were collected from 10 animals
per group according to the table below. Immunological readouts
included the measurement of SARS-CoV-2 spike antigen-specific-IgG
in the serum and BAL, SARS-CoV-2 spike antigen-specific IgA in the
BAL, neutralizing antibody responses against SARS-CoV-2 in the
serum and the numeration of immune cells in the lung, lymph nodes,
BALs and spleens at different time-points. These parameters are
summarized in Table 20.

Day 7
[0457] The quantification of SARS-CoV-2 spike IgG and IgA was
performed in serum or BAL samples obtained from immunized animals
using a cytometric bead array conjugated a recombinant SARS-CoV-2
ectodomain spike protein. To produce recombinant SARS-CoV-2 S
ectodomain protein, two codon-optimized constructs were generated
with linear sequence order encoding: a human IgG leader sequence,
the SARS-CoV-2 S ectodomain (amino acids 14-1211), a GGSG linker,
T4 Fibritin Foldon sequence, a GS linker, and finally an AviTag
(construct 1) or 6.times.-HisTag (construct 2). Each construct was
engineered with two sets of mutations to stabilize the protein in a
pre-fusion conformation. These included substitution of
RRAR>SGAG (residues 682 to 685, as in Walls et al 2020) at the
S1/S2 cleavage site and the introduction of two proline residues;
K983P, V984P, as in Walls et al 2020 and Wrapp et al 2020.
Avi/His-tagged trimers were produced by co-transfecting plasmid
constructs 1 and 2 (1:2 ratio) into FreeStyle 293-F Cells. Cells
were grown for three days and the supernatant (media) was recovered
by centrifugation. Recombinant S trimers were purified from media
by FPLC using a HisTrap HP Column (GE) and elution with 250 mM of
imidazole. After exchanging into either 10 mM Tris-HCl, pH 8.0 or
50 mM Bicine, pH 8.3, purified spike ectodomain trimers were
biotinylated by addition of biotin-protein ligase (Avidity, Aurora,
Colo.). Biotinylated spike ectodomain trimers were buffer exchanged
into PBS, sterile filtered, aliquoted, then stored at -80.degree.
C. until used. Following affinity purification of his-tagged
protein and enzymatic biotinylation, the resulting recombinant
SARS-CoV-2 trimers were passively absorbed onto streptavidin
functionalized fluorescent microparticles (Spherotech 3.6 um cat
#CPAK-3567-4K, peak 4). 500 .mu.g of biotinylated SARS2-CoV-2 was
incubated with 2.times.1e7 Streptavidin functionalized fluorescent
microparticles in 400 ul of 1% BSA PBS. Following coupling, the
SARS-CoV-2 spike conjugated beads were washed twice in 1 ml of 1%
BSA, PBS, 0.05% NaN3 prior to final resuspension to a concentration
of 1.times.10.sup.8 beads/mL. SARS-CoV-2 coupled beads were stored
at 4.degree. C. The loading of recombinant SARS2-CoV-2 spike onto
the beads was evaluated by staining 1.times.10.sup.5 beads with
dilutions ranging from lug to 2 ng/ml of the recombinant anti-SARS
spike antibody CR3022 and visualized with an anti-human IgG
secondary. IgG and IgA standards were obtained by covalent coupling
of isotype specific polyclonal antibodies to fluorescent particles.
Briefly, 0.2 mg of goat polyclonal anti-mouse IgG (southern Biotech
cat #1013-01), anti-IgM (cat #1 022-01), and anti-IgA (cat
#1040-01) antibodies in PBS were mixed with 5.times.1e7 fluorescent
microparticles each with a unique fluorescent intensity in the far
red channels (Spherotech 3.6 um cat #CPAK-3567-4K, peaks 1-3)
resuspended in 0.1 M MES buffer pH 5.0. An equal volume of EDC
(1-Ethyl-3-(3-dimethylaminopropyl)-carbodiimide), 10 mg/mL, in 0.1
M IVIES (2-(N-morpholino) ethanesulfonic acid) buffer pH 5.0, and
the mixture was incubated overnight at room temperature. The beads
were washed twice by pelleting by centrifugation and resuspension
in PBS. Following washing, beads were resuspended in 1% BSA, PBS
with 0.005% NaN3 as a preservative. BAL samples, diluted 1/4-8, or
serum samples were diluted to 1/1000-5000 in 50 .mu.l of PBS were
arrayed in 96 well u-bottom polystyrene plates along with 50 ul of
standards consisting of either mouse IgG, IgM, or IgA ranging from
1 .mu.g/ml to 2 ng/ml at 0.75.times. dilutions (southern biotech
IgM: cat #0106-01, IgG: cat #0107-01, IgA cat #0106-01). 5 .mu.l of
a suspension containing 5.times.1e5 of each SARS-CoV-2 spike,
anti-IgM, anti-IgA, and anti-IgG beads was added to the diluted
samples. The suspensions were mixed by pipetting and incubated for
15 mins at room temperature. The beads were washed by the addition
of 200 .mu.l of PBS and centrifugation at 3000 g for 5 min at room
temperature. The CBA particles were resuspended in a secondary
staining solution consisting of poly-clonal anti-IgG 488 (southern
Biotech cat #1010-30), and either a goat polyclonal anti-IgM
(southern Biotech cat #1020-09) or anti-IgA (southern Biotech cat
#1040-09) conjugated to PE diluted 1/400 in 1% BSA in PBS. The
suspension was incubated for 15 min in the dark at room
temperature. The beads were washed by the addition of 200 .mu.l of
PBS and pelleted by centrifugation at 3000 g for 5 min at room
temperature. The particles were resuspended in 75 .mu.l of PBS and
directly analyzed on a BD Cytoflex flow cytometer in plate mode at
sample rate of 100 ul per minute. Sample collection was stopped
following the acquisition of 75 .mu.L. Following acquisition, the
resulting FCS files were analyzed in flowJo (treestar). Briefly,
the beads were identified by gating on singlet 3.6 um particles in
log scale in the forward scatter and side scatter parameters.
APC-Cy7 channel fluorescence gates were used to segregate the
particles by bead identity. Geometric mean fluorescent intensity
was calculated in the PE and 488 channels. Best fit power curves
were generated from the Ig capture beads using the know
concertation of standards on a plate by plate basis. This formula
was applied to the MFI of the SARS-COV-2 spike particles for all
samples of the corresponding assay converting MFI to ng/ml or
.mu.g/ml. These calculated values were corrected for the dilution
factor.
[0458] A foci reduction neutralization test (FNRT) was used to
quantify the titer of neutralizing antibodies against SARS-CoV-2
isolate USA-WA1/2020. Vero E6 cells were grown on 96-well plates to
confluence. On the day of the infection phase of the assay, serial
dilutions (1:20-1:2560) of antisera were made and combined and
incubated with an equal volume of viral stock, at a specified
dilution for 30 min at RT, such that the final dilutions of
antisera ranged from (1:40-1:5120). The viral stock was diluted
from a concentrated working stock to produce an estimated 30 viral
focal units per well. After incubation, the sera:virus mixtures
were added to the wells (100 .mu.L), and infection allowed to
proceed for 1 hour on the Vero cells at 35.degree. C. At the
completion of the 1-hour incubation, a viscous overlay of Eagle's
MEM with 4% FBS and antibiotics and 1.2% Avicell were added to
sera:virus mixture on the cell monolayers such that the final
volume was 200 .mu.L per well. The infection was allowed to proceed
for 24 hr. The next day, each plate was fixed by submerging the
entire plate and contents in 10% formalin/PBS for 24 h. Detection
of virus foci reduction was performed on fixed 96 well plates.
Briefly, plates were rinsed in H.sub.2O, and methanol:hydrogen
peroxide added to the wells for 30 min with rocking to quench
endogenous peroxidase activity. After quenching, plates were rinsed
in H.sub.2O to remove methanol and 5% Blotto was added to the wells
as a blocking solution for 1 hour. For primary antibody detection,
a SARS-CoV-2 Spike/RBD antibody (Rabbit, Polyclonal,
SinoBiologicals Ct No. 40592-T62) was added to 5% Blotto and
incubated on the monolayers overnight. Plates are rinsed in 5
washes with PBS, and further incubated with a secondary antibody of
goat anti-rabbit IgG conjugated to horseradish peroxidase (Boster
Biological Technology Co., #BA1054-0.5) in 5% Blotto for 1 hour.
Plates were rinsed once with 0.05% tween in 1.times.PBS followed by
5 washes in 1.times.PBS. Detection of peroxidase activity was by
use of Impact DAB detection kit (Vector Labs #SK-4105) per
manufacturer's instructions. Brown foci are counted manually from
the scanned image of each well, recorded, and the reduction of foci
as compared to equivalent naive mouse sera controls was determined.
FRNT.sub.50 titers were also calculated using a 4PL curve fit.
[0459] The analysis of bronchoalveolar lavage (BAL) cells by flow
cytometry was performed as follows. BAL cells present were obtained
by centrifugation at 700.times.g for 5 min at 4.degree. C. of the
BAL fluids. Cells were resuspended in 500 .mu.l Red Blood Cell
Lysis Buffer [ACK buffer (10 mM KHCO3, pH 7.2-7.4, 150 mM NH4Cl and
0.1 mM EDTA)]. After 1 min, 2 ml of staining media (PBS+2% Fetal
Bovine Serum) with 2 mM EDTA. This media is referred to as SME. The
sample were then filtered by passing it through a 70 um Nitex.RTM.
Nylon filter membrane and into a clean 15-ml conical tube.
Following centrifugation at 700.times.g for 5 min at 4.degree. C.,
the cells were resuspended in 225 .mu.l SME. 25 ul of each sample
are then transferred into a 96-well plate for cell counting by flow
cytometry using Fluoresbrite Carboxylate YG 10 .mu.m microspheres.
The remaining of the cells were transferred into a separate
V-bottom 96-well plate for antibody staining for flow cytometric
analysis. The BAL cell samples were incubated for 10 min at
4.degree. C. in the dark with Fc-Block (1:1000 dilution), and then
stained with the following BAL staining panel: Autofluorescence

4.degree. C. in the dark, cells were washed with 200 ul SME. Cells
were then resuspension in 200 .mu.l 10% formalin before analysis on
FACSCanto II within 2 days.
[0460] The analysis of mediastinal lymph node by flow cytometry was
performed as follows. Mediastinal lymph node (mLN) were collected
and placed into separate wells of a 24-well plate containing 1 ml
Staining Media (PBS+2% Fetal Bovine Serum) with added 2 mM EDTA.
This media is referred to as SME. The mLN were gently grinded and
crushed by rubbing in-between two microscope slides, then rinsed
with 1 ml SME before transfer in a 15-ml conical tube. The volume
was brought to 10 ml using SME. The cell suspension were then
filtered by passing it through a 70 um Nitex.RTM. Nylon filter
membrane and into a clean 15-ml conical tube before rinsing the
filter membrane with an additional 2 ml SME. After centrifugation
at 1800 rpm at 4.degree. C. for 5 min, cells were resuspended with
1 ml SME. 50 ul of each sample were transferred into a 96-well
plate for cell counting by flow cytometry using Fluoresbrite
Carboxylate YG 10 .mu.m microspheres. 200-250 .mu.l of each sample
were transferred into 3 separate V-bottom 96-well plates for
antibody staining for flow cytometric analysis. mLN tissue were
stained with 3 different flow panels. The mLN samples were
incubated for 10 min at 4.degree. C. in the dark with Fc-Block

panel staining, cells are incubated with the antibody mix (50 ul
total volume) for 20 min at 4.degree. C. in the dark. Cells were
then washed with 200 .mu.l SME and resuspended in 200 .mu.l 10%
formalin (fixative) before analysis on FACSCanto II within 2 days.
The T cell panel consisted of CXCR5/CD185-FITC (clone J252D4; 1:50

[0461] The analysis of lung tissues by flow cytometry was performed
as follows. Excised lungs were cut into very small pieces using
scissors before addition Collagenase/DNase. After incubation at
37.degree. C. for 30 min, lung homogenates were diluted with 1 ml
SME. Digested tissues were gently grinded and crushed by using the
flat end of a syringe plunger onto a strainer before rinsing with
10-15 ml SME. After centrifugation at 1800 rpm and 4.degree. C. for
5 min, pellets were resuspended in 3 ml Red Blood Cell Lysis Buffer
[ACK buffer (10 mM KHCO3, pH 7.2-7.4, 150 mM NH4C1 and 0.1 mM

200 .mu.l of each sample were placed into 3 separate V-bottom
96-well plates for antibody staining for flow cytometric analysis.
Samples were incubated for 10 min at 4.degree. C. in the dark with
Fc-Block (1:1000 dilution) and then washed with 200 .mu.l SME
before staining with the same 3 panels used for the lymph

[0462] The analysis of splenocytes by flow cytometry was performed
as follows. Spleen were transferred into a 70-um cell strainer
fitted on a 50-ml conical tube and gently grinded and crushed by
using the flat end of a syringe plunger before rinsing the strainer

C. for 5 min, pellets are resuspended in 5 ml Red Blood Cell Lysis
Buffer [ACK buffer (10 mM KHCO3, pH 7.2-7.4, 150 mM NH4C1 and 0.1
mM EDTA)]. After incubation at room temperature for 5 min, 20 ml
SME was added to each lysate to dilute the ACK buffer. Cells were
then filtered by passing it through a 70 um Nitex.RTM. Nylon filter
membrane. Filtered were rinse with an additional 5 ml SME. After
centrifugation, cell pellets were resuspended in 20 ml SME. 50
.mu.l of each sample were placed into a 96-well plate for cell
counting by flow cytometry using Fluoresbrite Carboxylate YG 10
.mu.m microspheres. 200 .mu.l of each sample were placed into 3
separate V-bottom 96-well plates for antibody staining for flow
cytometric analysis. Samples were incubated for 10 min at 4.degree.
C. in the dark with Fc-Block (1:1000 dilution) and then washed with
200 .mu.l SME before staining with the same 3 panels used for the
lymph nodes.
[0463] Following a single intranasal administration, the
replication-deficient Ad5 vector expressing the RBD domain of Spike
(SEQ ID NO: 15) was demonstrated to stimulate the production of IgG
antibodies in the serum indicating the induction of systemic
responses as well as the production of IgG and IgA antibodies in
bronchoalveolar lavages indicating the induction of a mucosal
responses as shown in FIGS. 71A-71C. A dose response was observed
across the different antibody markers with the high dose vaccine
leading the highest responses and the low dose leading to a
marginal response while the mid-dose generated an intermediate
response. It is worth noting that at day 14 and day 28 with a
single high dose vaccine, spike-specific IgG response in the serum
reached very high level, exceeding 1 milligram per ml representing
approximately 5% of the total serum IgG. After an intranasal boost
at day 14 with the same vector, the IgA production in the BAL
increased significantly above the response induced by a single dose
of the vaccine IgG response at day 21 and day 28 while the impact
on the IgG responses was limited.
[0464] All ten animals (100%) tested from the group that received a
single administration of the high dose vaccine showed the presence
of neutralizing antibodies against SARS-CoV-2 as measured by focus
reduction neutralization test (FRNT) (FIGS. 72A-72J) while only
three out of five animals (60%) show significant neutralizing
response in the group that has received a single administration of
the mid-dose vaccine (FIGS. 73A-73E).
[0465] Intranasal administration of the vaccine induces the
recruitment and/or proliferation of innate and adaptive immune
cells in different immune compartments. FIGS. 74A-74L, 75A-75E,
76A-76J, and 77A-L present the variations in the number of immune
cells respectively in the lung, BAL, mediastinal lymph nodes and

high dose vaccine. Importantly, elevation on the number of CD19
cells, memory B cells, Germinal Center (GC) B cells and/or T
follicular helper (hf) cells observed in the lung, BAL and lymph
nodes and to a lesser extend in the spleen are indicative of the
ability of the vaccine to stimulate a long-lived humoral and
mucosal antibody response. In addition, the elevation of
macrophages, dendritic cells, CD4+ and/or CD8+ T cells observed in
the lung, BAL and lymph nodes and to a lesser extend in the spleen
are indicatives of the ability of the vaccine to stimulate mucosal
and systemic, innate and cell-mediated immune responses that are
anticipated to be of benefit in the context of SARS-CoV-2
infection. Results obtained with the lower vaccine doses were not
presented as they show a similar trend but at a lower level.
Example 14. Intranasal Administration of Ad5 Vector Expressing S1
Domain in C57BL/6 Mice
[0466] Replication-deficient Ad5 vector expressing the S1 domain
from the spike antigen of SARS-CoV-2 (SEQ ID NO: 13) was
administered intranasally to C57BL/6 mice to evaluate the induction
of systemic and mucosal immunity against SARS-CoV-2. C57BL/6 mice
received one or two intranasal administration of the Ad5 vector at
three different doses in a volume of 50 .mu.l as indicated in Table
19. High dose was 1.2E+09 ifu/ml (6E+08 ifu in 50 mid-dose 1.2E+09
ifu/ml (6E+07 ifu in 50 .mu.L) and Low dose 1.2E+08 ifu/ml (6E+06
ifu in 50 .mu.L) in A195 buffer. The control group received an
intranasal administration of 50 .mu.l of the A195 buffer alone. At
day 7, day 14, day 21 or day 28 post-vaccine administration, sera,
bronchoalveolar lavages (BAL) and tissues including lungs,
mediastinal lymph nodes and spleens were collected from 10 animals
per group according to the table below. Immunological readouts
included the measurement of SARS-CoV-2 spike antigen-specific-IgG
in the serum and BAL, SARS-CoV-2 spike antigen-specific IgA in the
BAL, neutralizing antibody responses against SARS-CoV-2 in the
serum and the numeration of immune cells in the lung, lymph nodes,
BALs and spleens at different time-points. These parameters are
summarized in Table 21.

IgA in serum or BAL samples, focus reduction neutralization tests
as well as the flow cytometric analysis of bronchoalveolar lavage
(BAL) cells, mediastinal lymph nodes, lung tissues and splenocytes
are described in Example 13B.
[0468] Following a single intranasal administration, the
replication-deficient Ad5 vector expressing the S1 domain of Spike
(SEQ ID NO: 13) was demonstrated to stimulate the production of IgG
antibodies in the serum indicating the induction of systemic
responses as well as the production of IgG and IgA antibodies in
bronchoalveolar lavages indicating the induction of a mucosal
responses as shown in FIGS. 78A-78C. A dose response was observed
across the different antibody markers with the high dose vaccine
leading to the highest responses and the low dose leading to a
marginal response while the mid-dose generated an intermediate
response. Overall, IgG responses in the serum and BALs were lower
with the S1 vector compared to the results obtained with the RBD
vector as presented in Example 13B. After an intranasal boost at
day 14 with the same vector, the IgA production in the BAL
increased significantly above the response induced by a single dose
of the vaccine IgG response at day 21 and day 28 while the impact
on the IgG responses was limited.
[0469] Three out of five animals tested from the group that
received a single administration of the high dose vaccine showed
significant induction of neutralizing antibodies against SARS-CoV-2
as measured by focus reduction neutralization test (FRNT) (FIGS.
79A-79E). In the single mid-dose group, two out of five animals
(FIG. 80B and D) show low neutralizing response (FIGS.
80A-80E).
[0470] Intranasal administration of the vaccine induces the
recruitment and/or proliferation of innate and adaptive immune
cells in different immune compartments. FIGS. 81A-81L, 82A-82E,
83A-83J, and 84A-L present the variations in the number of immune
cells respectively in the lung, BAL, mediastinal lymph nodes and
the spleen following the single intranasal administration of the
high dose vaccine. Importantly, elevation on the number of CD19
cells, memory B cells, Germinal Center (GC) B cells and/or T

CD8+ T cell responses in the lungs and spleens by flow cytometry,
the measurement of T cell response in the lungs and spleens by an
IFN-gamma ELISpot assay as well as the measurement of T cell
cytokines following in vitro recall with RBD-derived peptides.

[0479] The analysis of RBD-specific T cell responses by IFN-gamma
ELISpot in the spleens and lungs was performed as follows. Spleens
were transferred into a 70-um cell strainer fitted on a 50-ml
conical tube and gently grinded and crushed by using the flat end
of a syringe plunger before rinsing the strainer with 10-15 ml SME.
After centrifugation at 1800 rpm and 4.degree. C. for 5 min,
pellets are resuspended in 5 ml Red Blood Cell Lysis Buffer [ACK
buffer (10 mM KHCO3, pH 7.2-7.4, 150 mM NH4C1 and 0.1 mM EDTA)].
After incubation at room temperature for 5 min, 20 ml SME was added
to each lysate to dilute the ACK buffer. Cells were then filtered
by passing through a 70 um Nitex.RTM. Nylon filter membrane.
Filtered cells were rinsed with an additional 5 ml SME. After
centrifugation, cell pellets were resuspended in 20 ml SME. 50
.mu.l of each sample were placed into a 96-well plate for cell
counting by flow cytometry using Fluoresbrite Carboxylate YG 10
.mu.m microspheres.
[0480] Excised lungs were cut into very small pieces using scissors
before addition of Collagenase/DNase. After incubation at
37.degree. C. for 30 min, lung homogenates were diluted with 1 ml
SME. Digested tissues were gently grinded and crushed by using the
flat end of a syringe plunger onto a strainer before rinsing with
10-15 ml SME. After centrifugation at 1800 rpm and 4.degree. C. for
5 min, pellets were resuspended in 3 ml Red Blood Cell Lysis Buffer
[ACK buffer (10 mM KHCO3, pH 7.2-7.4, 150 mM NH4C1 and 0.1 mM
EDTA)]. After incubation at room temperature for 5 min. Samples
were diluted 1:2 by adding 3 ml SME to inactivate the lysis buffer.
Cells were filtered by passing it through a Nitex.RTM. Nylon filter
membrane and into a clean 50-ml conical tube. After rinsing with
additional 5-10 ml SME, cells were centrifuged before resuspending
the cell pellets in 1 ml SME. 50 .mu.l of each sample were placed
into a 96-well plate for cell counting by flow cytometry using
Fluoresbrite Carboxylate YG 10 .mu.m microspheres.
[0481] For analysis of T cell responses, a pool of 53 peptides
derived from a peptide scan through RBD of Spike Glycoprotein of
SARS-CoV-2 (319-541) was designed and synthesized by JPT (JPT
Peptide technologies, Berlin, Germany). Peptides were designed with
a length of 15 a.a. and an overlap of 11a.a. Before use, each vial
containing 15 nmol (appr. 25 .mu.g) of each peptide per vial was
reconstituted in 50 .mu.l of DMSO before dilution into complete
culture media.
[0482] Spleen and lung cell suspensions (150,000 cells/well) were
placed in individual wells of ELlspot plates (Millipore-Sigma) that
were pre-coated with anti-IFN-.gamma. (AN18, (5 .mu.g/ml)). Cells
were stimulated with the RBD peptide pool described above at 0.5 to
2.0 .mu.g/peptide/ml. Following 24 hr stimulation, plates were
stained with biotinylated anti-IFN-.gamma. (R4-6A2), followed by
washing steps, and incubation with streptavidin-ALP. Secreted
IFN-.gamma. was detected following incubation with NBT/NCPI
substrate for 7-10 min. The number of IFN-.gamma. spot-forming
cells were manually counted from digital images of each well.
Statistical analysis was performed in GraphPad Prism using a
Mann-Whitney test.
[0483] The analysis of CD4+ and CD8+ T cell responses in lung
tissues and spleens by flow cytometry was performed as follows.
Spleen and lung single cell suspensions were stimulated with the
RBD peptide pool for 5 hrs in the presence of Brefeldin A (5 hrs,
12.5 ug/mL concentration). Cells were then incubated on ice with a
combination of fluorescent dye-labelled antibodies including
anti-CD4-V500 (clone GK1.5; 1:200 dilution), anti-CD8a-APC-Fire750
(clone 53-6.7; 1:200 dilution), anti-CD11a/CD18-Pacific Blue
(H155-78; 1:200 dilution), anti-CD103-PE (M290; 1:200 dilution),
anti-CD69-FITC (H1-2F3; 1:200 dilution), anti-Ly6G-PerCP-Cy5.5
(clone 1A8; 1:200 dilution), anti-CD64-PerCP-Cy5.5 (clone
X54-5/7.1; 1:200 dilution), anti-B220/CD45R-PerCP (clone RA3-6B2;
1:200 dilution), and Red LIVE/DEAD (1:1000 dilution). Following
surface staining, cells were permeabilized using BD Biosciences
Cytofix/Cytoperm kit, and stained with anti-IFN-.gamma.-PE-Cy7
(XMG1.2; 1:200 dilution) and anti-TNF-.alpha.-APC (MP6-XT22; 1:200
dilution). Following incubation with the antibodies, cells were
washed and resuspended before analysis on FACSCanto II within 12
hours. Statistical analysis was performed in GraphPad Prism using a
Mann-Whitney test.
[0484] Protein levels of IFN.gamma., IL-2, IL-4, IL-5, IL-10,
IL-13, IL-17A and TNF.alpha. were quantified in culture
supernatants using the mouse-specific Milliplex.RTM. multi-analyte
panel kit MT17MAG-47K (Millipore; Sigma) and the MagPix.RTM.
instrument platform with related xPONENT.RTM. software (Luminex
Corporation). The readouts were analyzed with the standard version
of EMD Millipore's Milliplex.RTM. Analyst software. Statistical
analysis was performed in GraphPad Prism using a Mann-Whitney
test.
[0485] Following a single intranasal administration, the
replication-deficient Ad5 vector expressing the RBD domain of Spike
(SEQ ID NO: 15) was demonstrated to induce a significant production
of IFN-gamma producing T cells in the lung and spleen as shown in
FIGS. 88 A to D. A high frequency of IFN-.gamma.-producing
RBD-specific T cells were detected in the lung at 10- and 14-days
post-vaccination, reaching a mean response of 915 and 706 spot per
million input cells respectively. See FIG. 88. IFN-.gamma.
producing RBD-specific T cells were also detected by ELISpot in the
spleen--albeit at lower frequency compared to the lungs. This
suggests that functional effector T cells primed in response to
mucosal-delivered antigens can migrate to peripheral lymphoid
tissues. In addition, RBD-specific CD4+ and CD8+ T cells expressing
the early activation homing markers CD11 a and IFN-gamma and/or
TNF-alpha were also found at significant levels in the lungs (FIGS.
89 A to D) and spleens (FIGS. 90 A to D). The expression of the
integrin CD11a, which is only upregulated in recently activated T
cells and is required for optimal vascular adhesion in the tissue
and retention within the respiratory tract (Thatte J, Dabak V,
Williams M B, Braciale T J, Ley K. LFA-1 is required for retention
of effector CD8 T cells in mouse lungs. Blood. 2003 Jun. 15;
101(12):4916-22.), supporting the hypothesis that these cells were
recently recruited to the lung. The T cell responses were found at
higher levels in the lung and dominated by CD8+ T cells. Intranasal
RBD vector also induced high level tissue-resident memory CD4+ and
CD8+ T cells (TRM) in the lungs (FIGS. 91 A and B).
[0486] To assess whether vaccine-induced T cells might represent
resident memory T cells (Trm), the expression of the Trm markers
CD103 and CD69 (Takamura S. Persistence in Temporary Lung Niches: A
Survival Strategy of Lung-Resident Memory CD8+ T Cells. Viral
Immunol. 2017 July/August; 30(6):438-450. doi:
10.1089/vim.2017.0016.) was assessed on the lung CD4.sup.+ and
CD8.sup.+ cells. Consistent with the intranasal administration
route, induction of lung RDB-specific CD4.sup.+ and CD8.sup.+ Trm
expressing either IFN-.gamma., TNF-.alpha. or both cytokines were
observed (FIG. 95).
[0487] The data showed that intranasal administration of the RBD
vector vaccine induced T cells competent to produce IFN-.gamma. and
TNF-.alpha. cytokines that are associated with Th-1 biased cellular
response. In addition, we observed that the vaccine elicited high
frequencies of antigen-specific CD8.sup.+ T cells that generally
correlate with an IFN-regulated T cell response that is important
for control of viral infection. To further assess the cytokine
producing potential of the T cells from vaccinated mice, we
restimulated the splenic T cells with RBD peptides for 48 hours and
then used cytokine bead arrays to measure cytokine levels in the
supernatant. As expected, we observed induction of IFN-.gamma. and
TNF-.alpha. by the T cells, Moreover, we found that the T cells
from the vaccinated animals produced moderate levels of IL-10
compared to T cells from the vehicle control treated mice.
Importantly, Interleukin (IL)-4, IL-5, IL-13 and IL-17a levels in
the supernatant from re-stimulated cells derived from the
vaccinated mice were equivalent to that seen in cultures containing
peptide-stimulated cells from the vehicle control animals (FIG.
96).

prevaccination and Days 15, 30, 63 and 120 post-vaccination (e.g.,
about 2 weeks, about 1 month, about 2 months and about 4 months),
sera were collected after a single intranasal vaccination as
described in Table 25. Methods for the quantification of SARS-CoV-2

example demonstrated no significant decay in the measured
anti-spike IgG from serum between 30 days and 120 days post
vaccination. In embodiments, provided herein is a vaccine or RBD
vector, that when administered as a single intranasal dose to a
mammal induces an antibody response against the spike protein that
is durable for at least 4 months. In some embodiments provided
herein is a vaccine or RBD vector, that when administered as a
single intranasal dose to a mammal induces an antibody response
against the spike protein that is durable (given the absence of

at least about 6 months, at least about 7 months, at least about 8
months, at least about 9 months, at least about 10 months, at least
about 11 months or at least about 12 months (on year).
Example 19. Intranasal Administration of Ad5 Vector Expressing RBD

the Bone Marrow and Lung
[0490] The immunogenicity of an intranasal replication-defective
Ad5 vector encoding the RBD domain residues 302 to 543 (SEQ ID NO:
15) of SARS-Cov-2 was assessed in outbred CD-1 mice by measuring
RBD-specific plasma cells (antibody secreting cells; ASCs) in the
bone marrow (BM) and lung that produce spike-specific IgG and IgA.
At Days 69 post-vaccination, bone marrows and lungs were collected
after a single intranasal vaccination as described in Table 26.

Sample Vehicle control dose per group Immunization collection RBD
vector 3.78E+08 5 CD-1 Day 0 Day 69 ifu in 30 .mu.L
[0491] The detection of RBD-specific ASCs in the bone marrow (BM)
and lung that produce spike-specific IgG and IgA by ELISPOT is
summarized as follows. Single cell suspensions from bone marrow (2
tibia+2 femur/mouse) and lung cells were prepared from vaccinated
mice. Cells were serially diluted in duplicate in complete media
and incubated for 5 hours at 37.degree. C. on multiscreen cellulose
filter ELISPOT plates (Millipore) that were previously coated with
purified recombinant RBD protein (Sino Biological). RBD-specific
antibodies secreted by plasma cells present in these tissues were
detected using AP-conjugated goat anti-mouse IgG Ab (Jackson
ImmunoResearch) or AP-conjugated goat anti-mouse IgA (Jackson
ImmunoResearch). ELISPOTS were imaged and counted using S6 Ultra-V
Analyzer (Cellular Technology Limited).
[0492] Results are presented in FIG. 98. RBD-specific ASCs were
identified in the bone marrow of day 69 vaccinated mice. As these
ASCs are located in a niche that specifically supports the
long-term survival of ASCs, we predict that the systemic
RBD-specific antibody titers induced by the RBD vector will be
highly durable. Moreover, intranasal vaccination also resulted in
the establishment of a durable ASC population in the lung that
included IgA ASCs that can provide mucosal protection at the site
of future infection. It is known that infection with respiratory
viruses can also establish long-lived ASCs within the lung and that
these cells are important in early protection from reinfection.
Therefore, it is a reasonable supposition that the presence of
these intranasal vaccine-induced ASCs may also provide local
protection to the vaccinated animals. In embodiments provided
herein are compositions (e.g., RBD vector) and methods for inducing
bone marrow and lung resident memory antibody secreting cells. In
some embodiments provided herein is a vaccine or RBD vector, that
when administered as a single intranasal dose to a mammal induces
bone marrow and lung resident memory antibody secreting cells that
secrete both anti-spike IgG and IgA.

long-lived RBD-specific B cell memory in the mediastinal lymph
nodes and RBD-specific plasma cells (antibody secreting cells;
ASCs) in the bone marrow (BM). At Day 168 post-vaccination (e.g.,
24 weeks or 6 months), mediastinal lymph nodes and bone marrows
were collected after a single intranasal vaccination as described
in Table 27. Naive C57BL/6 mice (n=5) were used negative

Jo2; 1:200 dilution), SARS-CoV-2 RBD-PE (1:200 dilution),
SARS-CoV-2 RBD-APC (1:200 dilution), 7-AAD (1:1000 dilution),
CD3-PerCP-Cy5.5 (clone 17A2; 1:200 dilution), CD38-PE-Cy7 (clone
90; 1:400 dilution), CD19-APC-Fire750 (clone 6D5; 1:200 dilution),
CD138-BV421 (clone 281-2; 1:200 dilution) and IgD-BV510 (clone
11-26c.2a; 1:500 dilution). Cells were incubated with antibody mix
(50 ul total volume) for 20 min at 4.degree. C. in the dark and
then washed with 200 ul SME. Cell were resuspended in 200 ul SME
(no fixative) and immediately analyzed on FACSCanto II.
[0495] Results for RBD-specific memory B cells are presented in
FIG. 99. FIG. 99B shows a higher absolute number of RBD-specific
memory B cells present in the mediastinal lymph nodes of vaccinated
animals compared to naive animals. Detecting the presence of
antigen-specific memory B cells 168 days after a single intranasal
administration of the RBD vector provide a strong indication of the
long-live nature of RBD-specific B induced by the intranasal
vaccine. RBD-specific memory B cell present in mediastinal lymph
nodes would be well-suited to be rapidly respond to respiratory
infection such as SARS-CoV-2.
[0496] Measurement of ASCs in bone marrow followed the same method
as described in example 19. Results are presented in FIG. 100. Long
lived RBD-specific ASCs produced IgG and IgA antibodies were
detected in the bone marrow of most animals 168 days after single
intranasal administration of the RBD vector.
[0497] Discussion--Single-Dose Intranasal Vaccination with 51 and
RBD Adenoviral Vector Elicits Rapid and Durable Systemic and
Mucosal Immunity Against SARS-CoV-2 in Mice
[0498] The immunogenicity of the S1 and RBD vectors following a
single administration of a replication-defective Ad5 vector
encoding the S1 domain (residues 16 to 685) (SEQ ID NO: 13) or the
RBD domain (residues 302 to 543) (SEQ ID NO: 15) from the Wuhan-1
strain of SARS-CoV-2 (accession number QHD43416.1) to inbred
C57BL/6 and outbred CD-1 mice were assessed by measuring the
induction of spike-specific antibody levels in sera and
bronchoalveolar lavage (BAL) fluids. Each vaccine was evaluated at
three (3) different dose levels (high, medium or low) as described
above. Following single vaccine administration on day 0, sera,
bronchoalveolar lavage (BAL) samples were collected between days
7-28 (C57BL/6) or days 7-21 (CD-1). IgG and IgA antibodies specific
for SARS-CoV-2 spike were measured in serum or BAL samples using a
spike cytometric bead array. The functionality of these
vaccine-elicited antibodies was measured in live virus
neutralization assays. In addition to the induction of robust
neutralizing antibody responses and mucosal IgA against SARS-CoV-2,
RBD stimulated systemic and mucosal cell-mediated immune responses
characterized by a T-helper 1 (Th1) type cytokine profile and
through the induction of cytokine-producing CD4.sup.+ and CD8.sup.+
T cells, including lung-resident memory T (Trm) cells.
[0499] Systemic spike-specific IgG antibody responses were detected
in both strains of mice receiving a single intranasal
administration of either the S1 vector or RBD vector vaccine. FIGS.
78 and 85. At the medium and high vaccine dose, the RBD vector
induced a modestly larger serum spike-specific IgG response
compared to the S1 vector--an effect that was more pronounced in
the C57BL/6 mice compared to CD-1 mice. Moreover, intranasal
administration of either S1 or RBD vector led to a rapid elevation
of spike-specific IgG in the BAL of both strains of mice. Induction
of IgA following a single intranasal dose of S1 or RBD was also
demonstrated. Systemic spike-specific IgG antibody responses
induced by the RBD vector (encoding SEQ ID NO: 15) following
intranasal administration were also demonstrated to be durable with
no evidence of decline over time for up to 120 days
post-vaccination as presented in example 18. See FIG. 97. Moreover,
intranasal vaccination also resulted in the establishment of a
durable RBD-specific ASC and long-lived B cell memory population in
the lung environment that included IgA ASCs that can provide local
protection to the vaccinated animals. See FIGS. 98-100.
[0500] Intranasal administration of S1 vector or RBD vector
elicited neutralizing antibody responses against SARS-CoV-2 were
measured in a focus neutralization reduction test (FNRT) (similar
as the plaque reduction neutralization test (PRNT)) in infection
permissive Vero E6 cells using the wild-type SARS-CoV-2 isolate
USA-WA1/2020. The analysis included samples from C57BL/6 mice
4-weeks after vaccination with S1 and RBD using either the mid or
high vaccine dose, and samples from CD1 mice 3-weeks after
vaccination with the high vaccine dose of RBD vector (FIG. 94A).
Intranasal administration of RBD vector elicited significantly
greater neutralizing titers compared to use of S1 vector under all
conditions evaluated. At the highest dose, intranasal vaccination
with RBD vector induced neutralizing antibody responses above
background in 10/10 C57BL/6 and 8/10 CD-1 mice with a median titer
of 563 and 431 respectively (FIG. 94A). The level of the
neutralizing antibody response correlated tightly with magnitude of
the spike-specific serum IgG response measured in individual
animals (FIG. 94B), indicating that robust antibody responses to
administration with RBD vector were associated with the generation
of potentially protective neutralizing antibodies.
[0501] Examples 13, 15 and 17 demonstrate that a present vaccine
composition, e.g., an adenovirus-vectored vaccine encoding the RBD
sequence (SEQ ID NO: 15) of the SARS-CoV-2 spike protein configured
for intranasal administration, is highly immunogenic in both inbred
and outbred mice and elicits robust systemic and local mucosal
antibody and T cell responses. Following a single intranasal
vaccination, the RBD vector composition elicited a strong and
focused immune response against SARS-CoV-2 Spike through the
induction of functional antibodies that neutralize wild-type
SARS-CoV-2 infection of permissive cells as well as mucosal IgA and
cytokine-producing pulmonary CD4.sup.+ and CD8.sup.+ T cells.
Cell-mediated responses induced by the RBD vector composition were
biased toward an anti-viral response as demonstrated by the high
rates of antigen-specific CD8.sup.+ T cells and cytokine expression
that included IFN-.gamma. and TNF-.alpha.. The establishment of a
resident memory CD8+ T cell population in the lungs complements the
robust induction of mucosal IgA antibody against the spike protein
and represents an important addition to the overall immune response
to the RBD vector composition. These data also indicate that
intranasal administration of the RBD vector vaccine composition did
not initiate a potentially deleterious Th2 response but rather
induced the expected anti-viral T cell responses due to the
anti-viral response induced with use of an adenoviral vector
administered intranasally. See U.S. Pat. No. 9,605,275. Taken
altogether, the data show that intranasal administration of the
replication incompetent Ad5 vector expressing SARS-CoV-2 spike RBD
sequence (SEQ ID NO: 15) generates humoral and cellular immune
responses in both systemic and mucosal sites, particularly within
the lung, which represents a major site for infection and clinical
disease.
