[0002] This disclosure incorporates by reference the Sequence
Listing text copy submitted herewith, which was created on Oct. 20,
2020, entitled 008073_5117_US01_Sequence_Listingb.txt which is 73
kilobytes in size.
BACKGROUND OF THE DISCLOSURE
[0003] Blood coagulation proceeds through a complex and dynamic
biological pathway of interdependent biochemical reactions,
referred to as the coagulation cascade. Coagulation Factor VIII
(FVIII) and Factor IX (FIX) are key components in the cascade.
Factor VIII is recruited to bleeding sites, and forms a Xase
complex with activated Factor IX and Factor X (FX). The Xase
complex activates FX, which in turn activates prothrombin to
thrombin, which then activates other components in the coagulation
cascade to generate a stable clot (reviewed in Saenko et al.,
Trends Cardiovasc. Med., 9:185-192 (1999); Lenting et al., Blood,
92:3983-3996 (1998)).
[0004] Hemophilia B is a congenital X-linked bleeding disorder
characterized by a deficiency in Factor IX activity. Generally,
diminished Factor VIII/Factor IX activity inhibits a positive
feedback loop in the coagulation cascade. This causes incomplete
coagulation, which manifests as bleeding episodes with increased
duration, extensive bruising, spontaneous oral and nasal bleeding,
joint stiffness and chronic pain, and possibly internal bleeding
and anemia in severe cases. (Zhang et al., Clinic. Rev. Allerg.
Immunol., 37:114-124 (2009)).
[0005] Conventionally, hemophilia B is treated by Factor IX
replacement therapy, which consists of administering Factor IX
protein (e.g., plasma-derived or recombinantly-produced Factor IX)
to an individual with hemophilia B. Factor IX is administered
prophylactically to prevent or reduce frequency of bleeding
episodes, in response to an acute bleeding episode, and/or
perioperatively to manage bleeding during surgery. However, there
are several undesirable features of Factor IX replacement
therapy.
[0006] First, Factor IX replacement therapy is used to treat or
manage hemophilia B, but does not cure the underlying Factor IX
deficiency. Because of this, individuals with hemophilia B require
Factor IX replacement therapy for the duration of their lives.
Continuous treatment is expensive and requires the individual to
maintain strict compliance, as missing only a few prophylactic
doses can have serious consequences for individuals with severe
hemophilia B.
[0007] Second, because conventional Factor IX products have a
relatively short half-life in vivo, about 24 hours, prophylactic
Factor IX replacement therapy requires administration two or three
times weekly. This places a burden on the individual to maintain
compliance throughout their life. While third generation
"long-acting" Factor IX drugs may reduce the frequency of
administration, prophylactic Factor FIX replacement therapy with
these drugs still requires monthly, weekly, or more frequent
administration in perpetuity. For example, prophylactic treatment
with Nonacog beta pegol [pegylated recombinant Factor IX] (Novo
Nordisk, U.S. and EP regulatory approval pending) still requires
weekly administration (Collins P. W., et al., Blood,
124(26):3880-86 (2014)). Moreover, the long-term effects of
chemically modified biologics (e.g., pegylated polypeptides) are
not yet fully understood.
[0008] Third, up to 5% of severe hemophilia B patients Factor IX
replacement therapy form anti-Factor IX inhibitor antibodies,
rendering the therapy inefficient (Osooli and Berntorp, J. Intern.
Med., 277(1):1-15 (2015)). Unlike Factor VIII bypass therapies that
may be used to treat hemophilia A patients who have developed
anti-Factor VIII inhibitory antibodies, no Factor IX bypass therapy
exists for the treatment of hemophilia B.
[0009] Fourth, Factor IX replacement therapy is expensive, ranging
from about $1,000 to about $3,000 per dose, depending on the weight
of the patient (Hemophilia Federation of America online materials).
Thus, with twice weekly dosing, Factor IX replacement therapy may
cost up to $300,000 annually.
[0010] Gene therapy holds great promise for the treatment of
hemophilia B because it would remedy the underlying
under-expression of functional Factor IX activity (e.g., due to
missense or nonsense mutations), rather than provide a one-time
dose of Factor IX activity to the individual. Because of the
difference in the mechanism for providing Factor IX, as compared to
Factor IX replacement therapy, a single administration of a Factor
IX gene therapy vector may provide an individual with sufficient
levels of Factor IX for several years, if not longer. This reduces
the cost of treatment and eliminates the need for continued patient
compliance.
[0011] Proof of concept for Factor IX gene therapy treatment of
hemophilia B has been shown. See, e.g., Manno C. S., et al., Nat
Med., 12(3):342-47 (2006). However, questions remain as to whether
therapeutically effective amounts of Factor IX can be expressed for
sufficient periods of time. See, e.g., Giangrande, Semin Thromb
Hemost. 42(5):513-17 (2016).
[0012] Several attempts have been made to construct codon-optimized
Factor IX. For example, WO 2006/036502 discloses a codon-optimized
Factor IX AAV gene therapy vector with an ApoE HCR-1 enhancer and
an alpha-1 antitrypsin (AAT) promoter. Similarly, WO 2014/064277
and WO 2016/146757 disclose codon-optimized Factor VIII and Factor
IX AAV gene therapy vectors that include one or more copies of a
liver-specific SERPIN regulatory element. Finally, WO 2016/210170
discloses codon-optimized Factor IX AAV gene therapy vectors with
an ApoE HCR-1 enhancer and an alpha-1 antitrypsin (AAT)
promoter.
BRIEF SUMMARY OF DISCLOSURE
[0013] Accordingly, there is a need for improved Factor IX gene
therapy constructs. For example, there is a need for synthetic,
codon-altered nucleic acids encoding Factor IX that are more
efficiently packaged into, and delivered via, gene therapy vectors.
There is also a need for synthetic, codon-altered nucleic acids
that express Factor IX more efficiently. There is also a need for
codon-altered nucleic acids encoding Factor IX polypeptides with
improved folding properties, improved secretion from expressing
cells, and/or increased activity, as compared to wild-type Factor
IX. Such Factor IX encoding, codon-altered nucleic acids allow for
improved treatment of Factor IX deficiencies (e.g., hemophilia B).
The above deficiencies and other problems associated with the
treatment of Factor IX deficiencies (e.g., hemophilia B) are
reduced or eliminated by the disclosed codon-altered nucleic acids
encoding Factor IX proteins.
[0014] In one aspect, nucleic acid compositions (e.g.,
codon-altered polynucleotides) encoding Factor IX and Factor IX
variants are described. The nucleic acid compositions include
polynucleotides with high sequence identity to the CS02, CS03,
CS04, CS05, and CS06 sequences encoding Factor IX, as described
herein. The nucleic acid compositions described herein provide
increased Factor IX expression relative to wild-type Factor IX
coding sequences. The nucleic acid compositions also allow for
increased production of AAV-based gene therapy virions. In some
embodiments, the nucleic acid compositions described herein have
decreased GC content and or include fewer CpG dinucleotides, as
compared to wild-type sequences encoding Factor IX.
[0015] In some embodiments, a nucleic acid composition includes a
polynucleotide encoding Factor IX that has a nucleotide sequence
with at least 95% sequence identity (e.g., at least 95%, 96%, 97%,
98%, 99%, or 100% sequence identity) to a disclosed sequence
selected from CS02-FL-NA (SEQ ID NO: 5), CS02-MP-NA (SEQ ID NO:
13), CS03-FL-NA (SEQ ID NO: 6), CS03-1VIP-NA (SEQ ID NO: 14),
CS04-FL-NA (SEQ ID NO: 7), CS04-MP-NA (SEQ ID NO: 15), CS05-FL-NA
(SEQ ID NO: 8), CS05-MP-NA (SEQ ID NO: 16), CS06-FL-NA (SEQ ID NO:
9), and CS06-MP-NA (SEQ ID NO: 17).
[0016] In some embodiments, a nucleic acid composition includes a
polynucleotide encoding Factor IX that has a nucleotide sequence
with at least 95% sequence identity (e.g., at least 95%, 96%, 97%,
98%, 99%, or 100% sequence identity) to a disclosed sequence
encoding a Factor IX light chain (e.g., CS02-LC-NA (SEQ ID NO: 42),
CS03-LC-NA (SEQ ID NO: 44), CS04-LC-NA (SEQ ID NO: 46), CS05-LC-NA
(SEQ ID NO: 48), or CS06-LC-NA (SEQ ID NO: 50)) and a disclosed
sequence encoding a Factor IX heavy chain (e.g., CS02-HC-NA (SEQ ID
NO: 41), CS03-HC-NA (SEQ ID NO: 43), CS04-HC-NA (SEQ ID NO: 45),
CS05-HC-NA (SEQ ID NO: 47), or CS06-HC-NA (SEQ ID NO: 49)).
[0017] In some embodiments, a nucleic acid composition includes a
polynucleotide that encodes a Factor IX polypeptide having a light
chain, a heavy chain, and a polypeptide linker joining the
C-terminus of the light chain to the N-terminus of the heavy chain
(e.g., an activation peptide). The light chain of the Factor IX
polypeptide is encoded by a first nucleotide sequence with high
sequence identity to one of CS02-LC-NA (SEQ ID NO: 42), CS03-LC-NA
(SEQ ID NO: 44), CS04-LC-NA (SEQ ID NO: 46), CS05-LC-NA (SEQ ID NO:
48), and CS06-LC-NA (SEQ ID NO: 50). The heavy chain of the Factor
IX polypeptide is encoded by a second nucleotide sequence with high
sequence identity to one of CS02-HC-NA (SEQ ID NO: 41), CS03-HC-NA
(SEQ ID NO: 43), CS04-HC-NA (SEQ ID NO: 45), CS05-HC-NA (SEQ ID NO:
47), and CS06-HC-NA (SEQ ID NO: 49). The polypeptide linker
comprises a protease cleavage site (e.g., two Factor XIa cleavage
sites).
[0018] In some embodiments of the polynucleotides described above,
the polypeptide linker has an amino acid sequence with high
sequence identity to the wild-type Factor IX activation peptide
FIX-AP-AA (SEQ ID NO: 56; amino acids 192-226 of FIX-FL-AA (SEQ ID
NO: 2)). In some embodiments, the polypeptide linker is encoded by
a third nucleic acid sequence having high sequence identity to one
of CS02-AP-NA (SEQ ID NO: 57), CS03-AP-NA (SEQ ID NO: 58),
CS04-AP-NA (SEQ ID NO: 59), CS05-AP-NA (SEQ ID NO: 60), and
CS06-AP-NA (SEQ ID NO: 61).
[0019] In some embodiments, the codon-altered polynucleotides
described herein encode a pre-pro-Factor IX polypeptide, e.g.,
where the encoded Factor IX protein includes a signal peptide and a
pro-peptide. In some embodiments, the signal peptide, the
pro-peptide, or both the signal peptide and the pro-peptide are
encoded by a codon-altered sequence. In some embodiments, the
signal peptide, the pro-peptide, or both the signal peptide and the
pro-peptide are encoded by a wild-type sequence, while the portion
of the nucleic acid encoding the mature Factor IX single-chain
polypeptide (e.g., FIX-MP-AA (SEQ ID NO: 10); amino acids 47-461 of
FIX-FL-AA (SEQ ID NO: 2)) is codon altered.
[0020] In some embodiment, the codon-altered polynucleotides
described herein encode a Factor IX variant polypeptide, e.g.,
having one or more amino acid substitution with respect to the
wild-type Factor IX amino acid sequence (e.g., FIX-FL-AA (SEQ ID
NO: 2) or FIX-MP-AA (SEQ ID NO: 10)). In some embodiments, the
Factor IX variant is a hyperactive Factor IX variant with increased
Factor IX activity, as compared to wild-type Factor IX. In a
particular embodiment, the encoded Factor IX polypeptide has a
`Padua` R384L amino acid substitution (relative to the Factor IX
pre-pro-polypeptide sequence FIX-FL-AA (SEQ ID NO: 2), R338L amino
acid substitution relative to the mature Factor IX single-chain
sequence FIX-MP-AA (SEQ ID NO: 10)).
[0021] In one aspect, methods for treating hemophilia B are
described. The methods include administering to a patient in need
thereof a nucleic acid composition (e.g., a codon-altered Factor IX
polynucleotide construct) described herein (e.g., a polynucleotide
having high sequence identity to a CS02, CS03, CS04, CS05, or CS06
Factor IX coding sequence). In some embodiments, the Factor IX
polynucleotide construct is a mammalian gene therapy vector, as
described herein. In a particular embodiment, the Factor IX
polynucleotide construct is an adeno-associated virus (AAV) vector.
In some embodiments, the gene therapy vector includes one or more
copies of a liver-specific regulatory control element (e.g., 1 to 3
copies of a CRM8 regulatory control element).
[0022] In one aspect, methods for producing an adeno-associated
virus (AAV) particle are described. The method includes introducing
a nucleic acid composition (e.g., a codon-altered Factor IX
polynucleotide construct) described herein (e.g., a polynucleotide
having high sequence identity to a CS02, CS03, CS04, CS05, or CS06
Factor IX coding sequence) into a mammalian host cell, wherein the
polynucleotide is competent for replication in the mammalian host
cell.

DETAILED DESCRIPTION OF DISCLOSURE
I. Introduction
[0048] AAV-based gene therapy holds great promise for the treatment
of hemophilia. For hemophilia B, first clinical data are
encouraging in that FIX levels of about 10% can be maintained in at
least some patients for more than 1 year. For example, in initial
human trials demonstrated that hepatic artery catherization of
AVV-FIX constructs resulted in transient expression of Factor IX in
vivo. Kay M. et al., Nat Genet. 24(3):257-61 (2000). However, the
transduction resulted in modest activation of the immune system
against AAV-derived capsid antigens. Manno C. S. et al., Nat Med.
12(3):342-47 (2006) and Mingozzi F. et al., Nat Med. 13(4):419-22
(2007).
[0049] Non-viral vectors may be less immunogenic because they are
based on delivery of naked DNA or DNA associated with non-antigenic
carriers (e.g., inert polymers, lipids, or nano-particles).
However, cellular transfection rates of non-viral vectors are lower
than those for viral delivery vectors. Additionally, long-term
expression from non-viral vectors is hampered by the presence of
bacterial sequences used for large-scale production of the
constructs.
[0050] These challenges, however, cannot be addressed by simply
administering higher doses of the gene therapy construct. According
to current knowledge, the vector dose of an AAV-based gene therapy
vector should not be increased above 2.times.10.sup.12 vg/kg
bodyweight. This is because at such high doses a T cell immune
response is triggered, which destroys transduced cells and, as a
consequence, transgene expression is reduced or even eliminated.
Therefore, strategies to improve the expression of FIX are needed
to make FIX gene therapy a viable therapeutic option for hemophilia
B patients.
[0051] Thus, improved Factor IX polypeptide constructs that support
improved Factor IX expression and activity would improve both
therapeutic approaches. For example, viral delivery methods would
be improved by reducing the initial dose of the construct, thereby
reducing stimulation of the subject's immune system. Methods
relying on administration of naked DNA would be improved by
supporting greater Factor IX activity with fewer copies of the
therapeutic polynucleotide.
[0052] The present disclosure relates to the discovery of
codon-altered Factor IX variant coding sequences that solve these
and other problems associated with Factor IX gene therapy. For
example, the polynucleotides disclosed herein provide markedly
improved Factor IX expression and activity in a mammalian host. In
some implementations, these advantages are realized by using Factor
IX-encoding polynucleotides with high sequence identity to the
codon-altered CS02, CS03, CS04, CS05, and CS06 constructs. In some
embodiments, these sequences include significantly fewer CpG
dinucleotides, as compared to wild type constructs, as is more
fully described below.
[0053] Advantageously, the CS02, CS03, CS04, CS05, and CS06
codon-altered Factor IX sequences described herein provide superior
Factor IX expression in vivo, as compared to equivalent wild-type
sequences. For example, Example 1 shows that self-complementary AAV
vectors carrying a CS02, CS03, CS04, CS05, or CS06 codon-altered
Factor IX(R384L) coding sequence provide 20-fold to 40-fold
increases in Factor IX activity in vivo, relative to a
self-complementary AAV vector carrying a wild-type Factor IX coding
sequence. Similarly, 2-fold to 4-fold increases are seen in Factor
IX expression relative to a self-complementary AAV vector carrying
a wild-type Factor IX(R384L) coding sequence (Table 2).
[0054] Advantageously, the improved Factor IX activity generated
from the CS02, CS03, CS04, CS05, and CS06 codon altered sequences
can be further enhanced by introducing one or more copies of a
liver-specific regulatory element upstream of the Factor IX coding
sequence. For example, as demonstrated in Examples 2 and 3,
inclusion of one or more liver-specific CRM8 regulatory control
elements in the self-complementary AAV Factor IX vector further
increased Factor IX expression 2-fold to 3-fold in a mouse model
and 2-fold to 13-fold in human hepatocytes (Tables 3 and 4,
respectively). Likewise, inclusion of one or more copies of a
liver-specific CRM8 regulatory control element in a single-stranded
AAV Factor IX vector increased Factor IX activity 2-fold in vivo
(mouse model; Table 5) and up to 26-fold in human hepatocytes
(Table 6).
[0055] Surprisingly, while self-complementary AAV vectors encoding
a codon-altered Factor IX polypeptide lacking liver-specific CRM8
regulatory control elements provided greater increases in Factor IX
expression than similar single-stranded AAV vectors (compare the
6.2-fold increase in FIX activity provided by CS06-CRM.0-scV with
the 3.9-fold increase in Factor IX activity provided by
CS06-CRM.0-ssV (SEQ ID NO: 40) in Table 6), single-stranded AAV
Factor IX vectors containing multiple copies of the liver-specific
CRM8 regulatory control elements significantly outperformed similar
self-complementary AAV vectors (compare the 12.8-fold increase in
Factor IX activity provided by CS02-CRM8.3-scV, relative to
CS02-CRM8.0-scV, in Table 4 to the 16.8-fold increase in Factor IX
activity provided by CS06-CRM8.3-ssV (SEQ ID NO: 40), relative to
CS06-CRM8.0-scV, in Table 6).
II. Definitions
[0056] As used herein, the following terms have the meanings
ascribed to them unless specified otherwise.
[0057] As used herein, the terms "Factor IX" and "FIX" (with the
"IX" referring to the Roman numerals to mean "nine") are used
interchangeably, and refer to any protein with Factor IX activity
(e.g., active FIX, often referred to as "FIXa") or a protein
precursor (e.g., a pro-protein or a pre-pro-protein, often referred
to as pFIX and ppFIX) of a protein with Factor IX activity,
particularly Factor X cleavage activity in the presence of Factor
VIII, e.g., as measured using the one stage Factor IX clotting
assay described in Chapter 2.7.11 of the European Pharmacopoeia
9.0, the content of which is hereby incorporated by reference.
[0058] Factor IX is translated as an inactive, single-chain
polypeptide that includes a signal peptide, a propeptide, a light
chain, an activation peptide, and a heavy chain, often referred to
as a Factor IX pre-pro-polypeptide. The Factor IX pre-pro-peptide
undergoes post-translational processing to form an active Factor IX
protein (e.g., FIXa). This processing includes removal (e.g., by
cleavage) of the signal peptide, followed by removal (e.g., by
cleavage) of the propeptide, to form a single-chain mature Factor
IX polypeptide, containing the Factor IX light chain and Factor IX
heavy chain, which is still inactive. The mature Factor IX
polypeptide is further cleaved to excise the activation peptide
between the Factor IX light chain and Factor IX heavy chain,
forming an active Factor IX protein (e.g., FIXa). The Factor IX
light chain and Factor IX light chain remain associated through a
disulfide bond.
[0059] For example, the wild type human Factor IX pre-pro-protein
is first cleaved to release the encoded signal peptide (amino acids
1-28 of FIX-FL-AA (SEQ ID NO: 2)), forming a first single-chain
pro-protein. This single-chain pro-peptide is then cleaved to
release the propeptide (amino acids 29-46 of FIX-FL-AA (SEQ ID NO:
2)) to form a second single-chain pro-protein (e.g., FIX-MP-AA (SEQ
ID NO: 10), with the "MP" designation standing for "mature
protein"). The second single-chain pro-protein is then cleaved
twice between the FIX light chain and FIX heavy chain, by Factor
XIa, to release an activation peptide (amino acids 192-226 of
FIX-FL-AA (SEQ ID NO: 2)). This forms the active Factor IXa protein
consisting of separate light and heavy chains associated through a
disulfide bond. For additional information on the structure,
function, and activation of Factor IX see, e.g., Brandstetter H. et
al. P.N.A.S. USA, 92(21):9796-800 (1995), Hopfner KP et al.,
Structure, 7(8):989-96 (1999), and Gailani D. et al., Thromb Res.,
133 Suppl 1:S48-51 (2014), the contents of which are incorporated
herein by reference, in their entireties, for all purposes.
[0060] As described herein, this active Factor IXa protein can
include one or more variants, with the R338L variant finding
particular use in some embodiments. This is referred to as
"FIXp-MP-AA" (SEQ ID NO: 12) with the nucleic acid sequence being
referred to herein as "FIXp-MP-NA"; the "FIXp" stands for the
inclusion of the Padua R338L variant in the final protein. It
should be noted that codon-optimized sequences CS02-0506,
exemplified herein, encode the FIXp protein, including the R338L
variant. Thus, specifically included in the definition of FIX is
FIXp.
[0061] As used herein, the terms "Factor IX polypeptide" and "FIX
polypeptide" refer to a polypeptide having Factor IX serine
protease activity under particular conditions, e.g., as measured
using the one stage Factor IX clotting assay described in Chapter
2.7.11 of the European Pharmacopoeia 9.0. Factor IX polypeptides
include single-chain precursor polypetides (including Factor IX
pre-pro-polypeptides, Factor IX pro-peptides, and mature,
single-chain Factor IX polypeptides) which, when activated by the
post-translational processing described above, become active Factor
IX protein with Factor IX serine protease activity, as well as the
active Factor IX proteins, themselves. Specifically included in the
definition of Factor IX polypeptides are Factor IX polypeptides
including the R338L variant. In an exemplary embodiment, a human
Factor IX polypeptide refers to a polypeptide that includes an
amino acid sequence with high sequence identity (e.g., at least
85%, 90%, 95%, 99%, or more) to the portion of the wild type human
Factor IX polypeptide that includes the light and heavy chains,
FIX-MP-AA (SEQ ID NO: 10, shown in FIG. 11A) or to the portion of
the padua human Factor IX polypeptide that includes the light and
heavy chains, FIXp-MP-AA (SEQ ID NO: 12, shown in FIG. 12).
[0062] As used herein, the terms "Factor IX light chain," or simply
"light chain," refer to the polypeptide in an activated Factor IXa
protein derived from the N-terminal portion of the Factor IX
single-chain polypeptide, containing the Gla module, EGF-like 1,
and EGF-like 2 domains of Factor IX. In an exemplary embodiment,
amino acids 47-191 of the human pre-pro-Factor IX polypeptide
(FIX-FL-AA (SEQ ID NO: 2)) constitute a Factor IX light chain. As
used herein, the amino acid sequence of the wild-type Factor IX
light chain is referred to as FIX-LC-AA (SEQ ID NO: 62).
[0063] As used herein, the term "Factor IX heavy chain," or simply
"heavy chain," refers to the polypeptide in an activated Factor IXa
protein derived from the C-terminal portion of the Factor IX
single-chain polypeptide, containing the peptidase 51 domain of
Factor IX. In an exemplary embodiment, amino acids 227-461 of the
human pre-pro-Factor IX polypeptide (FIX-FL-AA (SEQ ID NO: 2))
constitute a Factor IX heavy chain. As used herein, the amino acid
sequence of the wild-type Factor IX heavy chain is referred to as
FIX-HC-AA (SEQ ID NO: 63) and FIXp-HC-AA (SEQ ID NO: 64) when the
R338L variant is included.
[0064] Generally, Factor IX light and heavy chains are expressed as
a single polypeptide chain, e.g., along with an activation peptide.
However, in some embodiments, a Factor IX light chain and Factor
VIII heavy chain are expressed as separate polypeptide chains
(e.g., co-expressed), and reconstituted to form a Factor IX protein
(e.g., in vivo or in vitro). In general, for the purposes of the
present invention, even if two chains are expressed separately,
they are generally on the same expression vector (e.g. the viral
genome), rather than on different expression vectors.
[0065] As used herein, the term "Factor IX activation peptide," or
simply "activation peptide," refers to the peptide excised from a
Factor IX single-chain polypeptide upon activation of the Factor
IXa protein. In an exemplary embodiment, amino acids 192-226 of the
human pre-pro-Factor IX polypeptide (FIX-FL-AA (SEQ ID NO: 2))
constitute a Factor IX activation peptide. As used herein, the
amino acid sequence of the wild-type Factor IX activation peptide
is referred to as FIX-AP-AA (SEQ ID NO: 56).
[0066] As used herein, the term "Factor IX signal peptide," or
simply "signal peptide," refers to the peptide excised from the
N-terminus of a Factor IX pre-pro-polypeptide by a signal
peptidase. The signal peptide directs newly translated Factor IX
pre-pro-protein to the endoplasmic reticulum. In an exemplary
embodiment, amino acids 1-28 of the human pre-pro-Factor IX
polypeptide (FIX-FL-AA (SEQ ID NO: 2)) constitute a Factor IX
signal peptide. As used herein, the amino acid sequence of the
wild-type Factor IX signal peptide is referred to as FIX-SP-AA (SEQ
ID NO: 37). A number of signal peptides of the invention are shown
in FIGS. 19 and 22.
[0067] As used herein, the term "Factor IX pro-peptide," or simply
"pro-peptide," refers to the peptide excised from the N-terminus of
a Factor IX pro-polypeptide (e.g., after cleavage of the signal
peptide) by Furin. The pro-peptide includes a .gamma.-carboxylation
recognition site that recruits carboxylase to the adjacent Gla
module, thereby promoting carboxylation of glutamine residues. In
an exemplary embodiment, amino acids 29-46 of the human
pre-pro-Factor IX polypeptide (FIX-FL-AA (SEQ ID NO: 2)) constitute
a Factor IX pro-peptide. As used herein, the amino acid sequence of
the wild-type Factor IX pro-peptide is referred to as FIX-PP-AA
(SEQ ID NO: 38).
[0068] As used herein, the term "Factor IX pre-pro-peptide," or
simply "pre-pro-peptide," refers to the aggregate of the Factor IX
signal peptide and pro-polypeptide. In an exemplary embodiment,
amino acids 1-46 of the human pre-pro-Factor IX polypeptide
(FIX-FL-AA (SEQ ID NO: 2)) constitute a Factor IX pre-pro-peptide.
As used herein, the amino acid sequence of the wild-type Factor IX
pre-pro-peptide is referred to as FIX-PPP-AA (SEQ ID NO: 36) with
the nucleic acid sequence, shown in FIG. 18, referred to as
FIX-PPP-NA (SEQ ID NO: 18) (with the corresponding FIXp-PPP-AA and
FIXp-PPP-NA when the R338L variant is used).
[0069] Unless otherwise specified herein, the numbering of Factor
IX amino acids refers to the corresponding amino acid in the
full-length, wild-type human Factor IX pre-pro-polypeptide sequence
(FIX-FL-AA), presented as SEQ ID NO: 2 in FIG. 3A. As such, when
referring to an amino acid substitution in a Factor IX polypeptide
disclosed herein, the recited amino acid number refers to the
analogous (e.g., structurally or functionally equivalent) and/or
homologous (e.g., evolutionarily conserved in the primary amino
acid sequence) amino acid in the full-length, wild-type Factor IX
pre-pro-polypeptide sequence. For example, an R384L amino acid
substitution refers to an R to L substitution at position 384 of
the full-length, wild-type human Factor IX pre-pro-peptide sequence
(FIX-FL-AA (SEQ ID NO: 2)), an R to L substitution at position 338
of the mature, wild-type Factor IX single-chain polypeptide
(FIX-MP-AA (SEQ ID NO: 10), an R to L substitution at position 346
of the full-length, wild-type human Factor IX pre-pro-peptide
isoform 2 sequence (FIX2-FL-AA (SEQ ID NO: 3)), an R to L
substitution at position 300 of the mature, wild-type human Factor
IX pre-pro-peptide isoform 2 sequence (FIX2-FL-AA (SEQ ID NO: 3)),
and an R to L substitution at position 158 of the wild-type human
Factor IX heavy chain sequence (FIX-HC-AA (SEQ ID NO: 63)). Thus,
all of these nomenclatures describe the same "Padua" amino acid
substitution, in different Factor IX constructs.
[0070] As described herein, the Factor IX amino acid numbering
system is dependent on whether the Factor IX pre-pro-peptide (e.g.,
amino acids 1-46 of the full-length, wild-type human Factor IX
sequence, inclusive of the signal peptide and pro-peptide) is
included. Where the pre-pro-peptide is included, the numbering is
referred to as "pre-pro-peptide inclusive" or "PPI". Where the
pre-pro-peptide is not included, the numbering is referred to as
"pre-pro-peptide exclusive" or "PPE." For example, R384L is PPI
numbering for the same amino acid substitution as R338L, in PPE
numbering. Similarly, the Factor IX amino acid numbering is also
dependent upon the Factor IX isoform. For example, R384L is isoform
1 numbering for the same amino acid substitution as R346L, in
isoform 2 numbering. Unless otherwise indicated, all amino acid
numbering refers to the corresponding amino acid in the
full-length, wild-type human Factor IX isoform 1 sequence
(FIX-FL-AA), presented as SEQ ID NO: 2 in FIG. 3A. This numbering
is identical for the FIXp-FL-AA (SEQ ID NO: 4), which has the same
amino acid sequence, aside from the R384L "Padua" mutation.
[0071] Non-limiting examples of wild type Factor IX polypeptides
include human pre-pro-Factor IX (e.g., GenBank accession nos. NP
000124.1 (FIX-FL-AA (SEQ ID NO: 2)) and NP 001300842.1 (FIX2-FL-AA
(SEQ ID NO: 3)), corresponding single chain Factor IX lacking the
signal peptide (amino acids 1-28 of the pre-pro-protein) and/or
propeptide (amino acids 29-46 of the pre-pro-protein), and natural
variants thereof; porcine pre-pro-Factor IX (e.g., UniProt
accession no. P00741), corresponding single chain Factor IX lacking
the signal peptide, and natural variants thereof; murine
pre-pro-Factor IX (e.g., UniProt accession no. P16294),
corresponding single chain Factor IX lacking the signal peptide,
and natural variants thereof; rat pre-pro-Factor IX (e.g., UniProt
accession no. P16296), corresponding single chain Factor IX lacking
the signal peptide, and natural variants thereof; and other
mammalian Factor VIII homologues (e.g., chimpanzee, ape, hamster,
guinea pig, etc.).
[0072] As used herein, a Factor IX polypeptide includes natural
variants and artificial constructs with Factor X cleavage activity
in the presence of Factor VIII. As used in the present disclosure,
Factor IX encompasses any natural variants, alternative sequences,
isoforms, or mutant proteins that retain some basal Factor IX
cleavage activity (e.g., at least 5%, 10%, 25%, 50%, 75%, or more
of the corresponding wild type activity as assayed in a one stage
clotting assay according to Chapter 2.7.11 of the European
Pharmacopoeia 9.0, which is specifically incorporated herein by
reference for its teachings of the Assay of Human Coagulation
Factor IX in chapter 2.7.11. Examples of Factor IX amino acid
variations (relative to FIX-FL-AA (SEQ ID NO: 2)) found in the
human population include, without limitation, 117N, L20S, C28R,
C28Y, V30I, R43L, R43Q, R43W, K45N, R46S, R46T, N481, S49P, L525,

W453R, and I454T. As discussed more fully below, this numbering is
relative to the wild type human FIX. Other amino acid variations
identified in the human population are known and can be found, for
example, using the National Center for Biotechnology Information's
("NCBI") variation viewer, accession number GCF 000001405.25.
Factor VIII proteins also include polypeptides containing
post-translational modifications.
[0073] Of particular use in the present disclosure is a FIX protein
that includes the so called "Padua" mutation, an arginine to
leucine change at position 338 of the mature single-strand Factor
IX protein (R338L), position 384 of the Factor IX
pre-pro-polypeptide (R384L). This mutation confers hyperfunctional
activity to the FIX protein. For example, it was shown that "Padua"
protein (e.g., Factor IX containing the R338L mutation) is 5-fold
to 10-fold more active than wild-type Factor IX in vivo. U.S.
Patent No. 6,531,298; Simioni P. et al., N Engl J Med.
361(17):1671-75 (2009), hereby incorporated by reference in its
entirety. Accordingly, the disclosure provides amino acid and
nucleic acid constructs that encode a Padua-FIX protein, sometimes
referred to herein as "FIXp" or "pFIX".
[0074] As used herein, the terms "Factor IX polynucleotide" and
"FIX polynucleotide" refer to a polynucleotide encoding a Factor IX
polypeptide having Factor IX serine protease activity under
particular conditions, e.g., as measured using the one stage Factor
IX clotting assay described in Chapter 2.7.11 of the European
Pharmacopoeia 9.0. Factor IX polynucleotides include
polynucleotides encoding Factor IX single-chain precursor
polypeptides, including Factor IX pre-pro-polypeptides, Factor IX
pro-peptides, and mature, single-chain Factor IX polypeptides,
which, when activated by the post-translational processing
described above, become active Factor IX protein with Factor IX
serine protease activity. Specifically included in the definition
of Factor IX polynucleotides are polynucleotides encoding a Factor
IX polypeptide that includes the R338L variant. In an exemplary
embodiment, a human Factor IX polynucleotide refers to a
polynucleotide that encodes a polypeptide that includes an amino
acid sequence with high sequence identity (e.g., at least 85%, 90%,
95%, 99%, or more) to the portion of the wild type human Factor IX
polypeptide that includes the light and heavy chains, FIX-MP-AA
(SEQ ID NO: 10, shown in FIG. 11A) or to the portion of the padua
human Factor IX polypeptide that includes the light and heavy
chains, FIXp-MP-AA (SEQ ID NO: 12, shown in FIG. 12).
[0075] As described herein, Factor IX polynucleotides can include
regulatory elements, such as promoters, enhancers, terminators,
polyadenylation sequences, and introns, as well viral packaging
elements, such as inverted terminal repeats ("ITRs"), and/or other
elements that support replication of the polynucleotide in a
non-viral host cell, e.g., a replicon supporting propagation of the
polynucleotide, e.g., in a bacterial, yeast, or mammalian host
cell.
[0076] Of particular use in the present disclosure are
codon-altered Factor IX polynucleotides. As described herein, the
codon-altered FIX polynucleotides provide increased expression of
transgenic Factor IX in vivo, as compared to the level of Factor IX
expression provided by a natively-coded Factor IX construct (e.g.,
a polynucleotide encoding the same Factor IX amino acid sequence
using the wild-type human codons). As used herein, the term
"increased expression" refers to an increased level of transgenic
Factor IX protein in the blood of an animal administered the
codon-altered polynucleotide encoding Factor IX, as compared to the
level of transgenic Factor IX protein in the blood of an animal
administered a natively-coded Factor IX construct. Increased
expression of the protein leads to an increase in Factor IX
activity; thus, increased expression leads to increased
activity.
[0077] In some embodiments, increased expression refers to at least
25% greater transgenic Factor IX polypeptide in the blood of an
animal administered the codon-altered Factor IX polynucleotide, as
compared to the level of transgenic Factor IX polypeptide in the
blood of an animal administered a natively-coded Factor IX
polynucleotide. For the purpose of the present disclosure,
increased expression refers to an effect generated by the
alteration of the codon sequence, rather than hyperactivity caused
by an underlying amino acid substitution, e.g., a "Padua" mutation.
That is, the expression level obtained from a codon-optimized
sequence encoding a "Padua" Factor IX polynucleotide is compared
relative to the expression level obtained from a natively-coded
"Padua" protein. In some embodiments, increased expression refers
to at least 50% greater, at least 75% greater, at least 100%
greater, at least 3-fold greater, at least 4-fold greater, at least
5-fold greater, at least 6-fold greater, at least 7-fold greater,
at least 8-fold greater, at least 9-fold greater, at least 10-fold
greater, at least 15-fold greater, at least 20-fold greater, at
least 25-fold greater, at least 30-fold greater, at least 40-fold
greater, at least 50-fold greater, at least 60-fold greater, at
least 70-fold greater, at least 80-fold greater, at least 90-fold
greater, at least 100-fold greater, at least 125-fold greater, at
least 150-fold greater, at least 175-fold greater, at least
200-fold greater, at least 225-fold greater, or at least 250-fold
greater transgenic Factor IX polypeptide in the blood of an animal
administered the codon-altered Factor IX polynucleotide, as
compared to the level of transgenic Factor IX polypeptide in the
blood of an animal administered a natively coded Factor IX
polynucleotide. Factor IX polypeptide levels in the blood of an
animal can be measured, for example, using an ELISA assay specific
for Factor IX polypeptide.
[0078] By "Factor IX activity" or "Factor IX serine protease
activity" herein is meant the ability to cleave a Factor X
polypeptide in the presence of a Factor VIIIa co-factor, e.g., via
hydrolysis of the Arg194-Ile195 peptide bond in wild-type Factor
IX, thus activating Factor X to Factor Xa. The activity levels can
be measured using any Factor IX activity known in the art; suitable
assays are outlined herein; an exemplary assay for determining
Factor IX activity is the one stage Factor IX clotting assay
described in Chapter 2.7.11 of the European Pharmacopoeia 9.0, used
in the examples provided herein. In some embodiments, human plasma
deficient of FIX activity is used as a control in the one stage
clotting assay to determine the Factor IX specificity.
[0079] Because certain Factor IX variants have enhanced specific
activities as compared to wild type Factor IX in vivo, e.g., the
human `Padua` variant has 5-fold to 10-fold greater Factor IX
serine protease activity than does natively-coded type human Factor
IX, in some embodiments, the therapeutic potential of a Factor IX
polynucleotide composition is evaluated by the increase in Factor
IX activity in the blood of an animal administered a Factor IX
polynucleotide, e.g., instead of or in addition to increased Factor
IX expression. In some embodiments, as used herein, increased
Factor IX activity refers to a greater increase in Factor IX
activity in the blood of an animal administered a codon-altered
Factor IX polynucleotide, relative to a baseline Factor IX activity
in the blood of the animal prior to administration of the
codon-altered Factor IX polynucleotide, as compared to the increase
in Factor IX activity in the blood of an animal administered a
natively-coded Factor IX polynucleotide, relative to a baseline
Factor IX activity in the blood of the animal prior to
administration of the natively-coded Factor IX polynucleotide. In
some embodiments, increased Factor IX activity refers to at least a
25% greater increase in Factor IX activity in the blood of an
animal administered the codon-altered Factor IX polynucleotide,
relative to a baseline level of Factor IX activity in the blood of
the animal prior to administration of the codon-altered Factor IX
polynucleotide, as compared to the increase in the level Factor IX
activity in the blood of an animal administered a natively-coded
Factor IX polynucleotide, relative to the baseline level of Factor
IX activity in the animal prior to administration of the
natively-coded Factor IX polynucleotide. In some embodiments,
increased Factor IX activity refers to at least 50% greater, at
least 75% greater, at least 100% greater, at least 3-fold greater,
at least 4-fold greater, at least 5-fold greater, at least 6-fold
greater, at least 7-fold greater, at least 8-fold greater, at least
9-fold greater, at least 10-fold greater, at least 15-fold greater,
at least 20-fold greater, at least 25-fold greater, at least
30-fold greater, at least 40-fold greater, at least 50-fold
greater, at least 60-fold greater, at least 70-fold greater, at
least 80-fold greater, at least 90-fold greater, at least 100-fold
greater, at least 125-fold greater, at least 150-fold greater, at
least 175-fold greater, at least 200-fold greater, at least
225-fold greater, or at least 250-fold greater increase in Factor
IX activity in the blood of an animal administered the
codon-altered Factor IX polynucleotide, relative to a baseline
level of Factor IX activity in the blood of the animal prior to
administration of the codon-altered Factor IX polynucleotide, as
compared to the increase in the level Factor IX activity in the
blood of an animal administered a natively-coded Factor IX
polynucleotide, relative to the baseline level of Factor IX
activity in the animal prior to administration of the
natively-coded Factor IX polynucleotide. Activity is measured using
the one stage Factor IX clotting assay described in Chapter 2.7.11
of the European Pharmacopoeia 9.0, as described herein.
[0080] As used herein, the term "hemophilia" refers to a group of
disease states broadly characterized by reduced blood clotting or
coagulation. Hemophilia may refer to Type A, Type B, or Type C
hemophilia, or to the composite of all three diseases types. Type A
hemophilia (hemophilia A) is caused by a reduction or loss of
factor VIII (FVIII) activity and is the most prominent of the
hemophilia subtypes. Type B hemophilia (hemophilia B) results from
the loss or reduction of factor IX (FIX) clotting function. Type C
hemophilia (hemophilia C) is a consequence of the loss or reduction
in factor XI (FXI) clotting activity. Hemophilia A and B are
X-linked diseases, while hemophilia C is autosomal. Conventional
treatments for hemophilia include both prophylactic and on-demand
administration of clotting factors, such as FVIII, FIX, including
Bebulin.RTM.--VH, and FXI, as well as FEIBA-VH, desmopressin, and
plasma infusions.
[0081] As used herein, the term "Factor IX gene therapy," or "FIX
gene therapy," includes any therapeutic approach of providing a
nucleic acid encoding Factor IX to a patient to relieve, diminish,
or prevent the reoccurrence of one or more symptoms (e.g., clinical
factors) associated with a Factor IX deficiency (e.g., hemophilia
B). The term encompasses administering any compound, drug,
procedure, or regimen comprising a nucleic acid encoding a Factor
IX molecule, including any modified form of Factor IX (e.g., a
Factor VIII R384L variant), for maintaining or improving the health
of an individual with a Factor IX deficiency (e.g., hemophilia B).
One skilled in the art will appreciate that either the course of
FIX gene therapy or the dose of a FIX gene therapy therapeutic
agent can be changed, e.g., based upon the results obtained in
accordance with the present disclosure.
[0082] The terms "therapeutically effective amount or dose" or
"therapeutically sufficient amount or dose" or "effective or
sufficient amount or dose" refer to a dose that produces
therapeutic effects for which it is administered. For example, a
therapeutically effective amount of a drug useful for treating
hemophilia can be the amount that is capable of preventing or
relieving one or more symptoms associated with hemophilia.
[0083] In some embodiments, a therapeutically effective treatment
results in a decrease in the frequency and/or severity of bleeding
incidents in a subject.
[0084] As used herein, the term "gene" refers to the segment of a
DNA molecule that codes for a polypeptide chain (e.g., the coding
region). In some embodiments, a gene is positioned by regions
immediately preceding, following, and/or intervening the coding
region that are involved in producing the polypeptide chain (e.g.,
regulatory elements such as a promoter, enhancer, polyadenylation
sequence, 5'-untranslated region, 3'-untranslated region, or
intron).
[0085] As used herein, the term "regulatory elements" refers to
nucleotide sequences, such as promoters, enhancers, terminators,
polyadenylation sequences, introns, etc., that provide for the
expression of a coding sequence in a cell.
[0086] As used herein, the term "promoter element" refers to a
nucleotide sequence that assists with controlling expression of a
coding sequence. Generally, promoter elements are located 5' of the
translation start site of a gene. However, in certain embodiments,
a promoter element may be located within an intron sequence, or 3'
of the coding sequence. In some embodiments, a promoter useful for
a gene therapy vector is derived from the native gene of the target
protein (e.g., a Factor VIII promoter). In some embodiments, a
promoter useful for a gene therapy vector is specific for
expression in a particular cell or tissue of the target organism
(e.g., a liver-specific promoter). In yet other embodiments, one of
a plurality of well characterized promoter elements is used in a
gene therapy vector described herein. Non-limiting examples of
well-characterized promoter elements include the CMV early
promoter, the (3-actin promoter, and the methyl CpG binding protein
2 (MeCP2) promoter. In some embodiments, the promoter is a
constitutive promoter, which drives substantially constant
expression of the target protein. In other embodiments, the
promoter is an inducible promoter, which drives expression of the
target protein in response to a particular stimulus (e.g., exposure
to a particular treatment or agent). For a review of designing
promoters for AAV-mediated gene therapy, see Gray et al. (Human
Gene Therapy 22:1143-53 (2011)), the contents of which are
expressly incorporated by reference in their entirety for all
purposes.
[0087] As used herein, a "CRM8" element refers to cis-acting
regulatory module derived from the SERPINA1 gene (NCBI accession
number NM 000295.4) that enhances expression of an operatively
linked gene, e.g., a sequence encoding a Factor IX polypeptide, in
a liver-specific fashion having high sequence identity to SEQ ID
NO: 39. As used herein, a CRM8 element refers to a single copy of
the regulatory element which, in some embodiments, is included in
one or more copies within a Factor IX polynucleotide, e.g., 1, 2,
3, or more copies. For further information on CRM elements, such as
CRM8, see Chuah M K et al., Mol Ther., 22(9):1605-13 (2014), which
is hereby incorporated by reference.
[0088] As used herein an "MVM intron" refers to an intron sequence
derived from minute virus of mice having high sequence identity to
SEQ ID NO: 53. For further information on the MVM intron itself,
see Haut and Pintel, J Virol. 72(3):1834-43 (1998), and use of the
MVM intron in AAV gene therapy vectors, see Wu Z et al., Mol Ther.,
16(2):280-9 (2008), both of which are hereby incorporated by
reference.
[0089] As used herein, the term "operably linked" refers to the
relationship between a first reference nucleotide sequence (e.g., a
gene) and a second nucleotide sequence (e.g., a regulatory control
element) that allows the second nucleotide sequence to affect one
or more properties associated with the first reference nucleotide
sequence (e.g., a transcription rate). In the context of the
present disclosure, a regulatory control element is operably linked
to a Factor IX transgene when the regulatory element is positioned
within a gene therapy vector such that it exerts an affect (e.g., a
promotive or tissue selective affect) on transcription of the
Factor IX transgene.
[0090] As used herein, the term "vector" refers to any nucleic acid
construct used to transfer a Factor IX nucleic acid into a host
cell. In some embodiments, a vector includes a replicon, which
functions to replicate the nucleic acid construct. Non-limiting
examples of vectors useful for gene therapy include plasmids,
phages, cosmids, artificial chromosomes, and viruses, which
function as autonomous units of replication in vivo. In some
embodiments, a vector is a viral vector for introducing a Factor IX
nucleic acid into the host cell. Many modified eukaryotic viruses
useful for gene therapy are known in the art. For example,
adeno-associated viruses (AAVs) are particularly well suited for
use in human gene therapy because humans are a natural host for the
virus, the native viruses are not known to contribute to any
diseases, and the viruses illicit a mild immune response.
[0091] As used herein, the term "Factor IX viral vector" refers to
a recombinant virus comprising a Factor IX polynucleotide, encoding
a Factor IX polypeptide, which is sufficient for expression of the
Factor IX polypeptide when introduced into a suitable animal host
(e.g., a human). Specifically included within the definition of
Factor IX viral vector are recombinant viruses in which a
codon-altered Factor IX polynucleotide, which encodes a Factor IX
polypeptide, has been inserted into the genome of the virus. Also
specifically included within the definition of Factor IX viral
vectors are recombinant viruses in which the native genome of the
virus has been replaced with a Factor IX polynucleotide, which
encodes a Factor IX polypeptide. Included within the definition of
Factor IX viral vectors are recombinant viruses comprising a Factor
IX polynucleotide, which encodes a "Padua" variant of Factor
IX.
[0092] As used herein, the term "Factor IX viral particle" refers
to a viral particle encapsulating a Factor IX polynucleotide,
encoding a Factor IX polypeptide, which is specific for expression
of the Factor IX polypeptide when introduced into a suitable animal
host (e.g., a human). Specifically included within the definition
of Factor IX viral particles are recombinant viral particles
encapsulating a genome in which a codon-altered Factor IX
polynucleotide, which encodes a Factor IX polypeptide, has been
inserted. Also specifically included within the definition of
Factor IX viral particles are recombinant viral particles
encapsulating a Factor IX polynucleotide, which encodes a Factor IX
polypeptide, which replaces the natice genome of the virus.
Included within the definition of Factor IX viral particles are
recombinant viral particles encapsulating a Factor IX
polynucleotide, which encodes a "Padua" variant of Factor IX.
[0093] By "AAV" or "adeno-associated virus" herein is meant a
Dependoparvovirus within the Parvoviridae genus of viruses. As used
herein, AAV can refer to a virus derived from a naturally occurring
"wild-type" AAV genome into which a Factor IX polynucleotide has
been inserted, a recombinant virus derived from a recombinant
Factor IX polynucleotide packaged into a capsid using capsid
proteins encoded by a naturally occurring AAV cap gene, or a
recombinant virus derived from a recombinant Factor IX
polynucleotide packaged into a capsid using capsid proteins encoded
by a non-natural capsid cap gene. Included within the definition of
AAV are AAV type 1 (AAV1), AAV type 2 (AAV2), AAV type 3 (AAV3),
AAV type 4 (AAV4), AAV type 5 (AAV5), AAV type 6 (AAV6), AAV type 7
(AAV7), AAV type 8 (AAV8), and AAV type 9 (AAV9) viruses
encapsulating a Factor IX polynucleotide and viruses formed by one
or more variant AAV capsid proteins encapsulating a Factor IX
polynucleotide.
[0094] By "AAV8," "AAV-8," or "AAV serotype 8" herein is meant a
virus formed by an AAV8 capsid viral protein that encapsulates a
Factor IX polynucleotide.
[0095] As used herein, the term "CpG" refers to a cytosine-guanine
dinucleotide along a single strand of DNA, with the "p"
representing the phosphate linkage between the two.
[0096] As used herein, the term "CpG island" refers to a region
within a polynucleotide having a statistically elevated density of
CpG dinucleotides. As used herein, a region of a polynucleotide
(e.g., a polynucleotide encoding a codon-altered Factor IX protein)
is a CpG island if, over a 200-base pair window: (i) the region has
GC content of greater than 50%, and (ii) the ratio of observed CpG
dinucleotides per expected CpG dinucleotides is at least 0.6, as
defined by the relationship:
N[CpG]*N[length of window]/N[C]*N[G].gtoreq.0.6.
For additional information on methods for identifying CpG islands,
see Gardiner-Garden M. et al., J Mol Biol., 196(2):261-82 (1987),
the content of which is expressly incorporated herein by reference,
in its entirety, for all purposes.
[0097] As used herein, the term "nucleic acid" refers to
deoxyribonucleotides or ribonucleotides and polymers thereof in
either single- or double-stranded form, and complements thereof.
The term encompasses nucleic acids containing known nucleotide
analogs or modified backbone residues or linkages, which are
synthetic, naturally occurring, and non-naturally occurring, which
have similar binding properties as the reference nucleic acid, and
which are metabolized in a manner similar to the reference
nucleotides. Examples of such analogs include, without limitation,
phosphorothioates, phosphoramidates, methyl phosphonates,
chiral-methyl phosphonates, 2-O-methyl ribonucleotides, and
peptide-nucleic acids (PNAs). However, particularly useful
embodiments herein, for use in gene therapy in patients, use
phosphodiester bonds.
[0098] By "nucleic acid compositions" herein is meant any molecule
or formulation of a molecule that includes a Factor IX
polynucleotide, encoding a Factor IX polynucleotide. Included
within the definition of nucleic acid compositions are Factor IX
polynucleotides, aqueous solutions of Factor IX polynucleotides,
viral particles encapsulating a Factor IX polynucleotide, and
aqueous formulations of viral particles encapsulating a Factor IX
polynucleotide. A nucleic acid composition, as disclosed herein,
includes a codon-altered FIX gene, that encodes a FIX
polypeptide.
[0099] The term "amino acid" refers to naturally occurring and
non-natural amino acids, including amino acid analogs and amino
acid mimetics that function in a manner similar to the naturally
occurring amino acids. Naturally occurring amino acids include
those encoded by the genetic code, as well as those amino acids
that are later modified, e.g., hydroxyproline, y-carboxyglutamate,
and O-phosphoserine. Naturally occurring amino acids can include,
e.g., D- and L-amino acids. As to amino acid sequences, one of
ordinary skill in the art will recognize that individual
substitutions, deletions or additions to a nucleic acid or peptide
sequence that alters, adds or deletes a single amino acid or a
small percentage of amino acids in the encoded sequence is a
"conservatively modified variant" where the alteration results in
the substitution of an amino acid with a chemically similar amino
acid. Conservative substitution tables providing functionally
similar amino acids are well known in the art. Such conservatively
modified variants are in addition to and do not exclude polymorphic
variants, interspecies homologs, and alleles of the disclosure.
[0100] Conservative amino acid substitutions providing functionally
similar amino acids are well known in the art. Dependent on the
functionality of the particular amino acid, e.g., catalytic,
structural, or sterically important amino acids, different
groupings of amino acid may be considered conservative
substitutions for each other. Table 1 provides groupings of amino
acids that are considered conservative substitutions based on the
charge and polarity of the amino acid, the hydrophobicity of the
amino acid, the surface exposure/structural nature of the amino
acid, and the secondary structure propensity of the amino acid.

[0101] The terms "identical" or percent "identity," in the context
of two or more nucleic acids or peptide sequences, refer to two or
more sequences or subsequences that are the same or have a
specified percentage of amino acid residues or nucleotides that are
the same (i.e., about 60% identity, preferably 65%, 70%, 75%, 80%,
85%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99%, or higher
identity over a specified region, when compared and aligned for
maximum correspondence over a comparison window or designated
region) as measured using a BLAST or BLAST 2.0 sequence comparison
algorithms with default parameters described below, or by manual
alignment and visual inspection.
[0102] As is known in the art, a number of different programs may
be used to identify whether a protein (or nucleic acid as discussed
below) has sequence identity or similarity to a known sequence.
Sequence identity and/or similarity is determined using standard
techniques known in the art, including, but not limited to, the
local sequence identity algorithm of Smith & Waterman, Adv.
Appl. Math., 2:482 (1981), by the sequence identity alignment
algorithm of Needleman & Wunsch, J. Mol. Biol., 48:443 (1970),
by the search for similarity method of Pearson & Lipman, Proc.
Natl. Acad. Sci. U.S.A., 85:2444 (1988), by computerized
implementations of these algorithms (GAP, BESTFIT, FASTA, and
TFASTA in the Wisconsin Genetics Software Package, Genetics
Computer Group, 575 Science Drive, Madison, Wis.), the Best Fit
sequence program described by Devereux et al., Nucl. Acid Res.,
12:387-395 (1984), preferably using the default settings, or by
inspection. Preferably, percent identity is calculated by FastDB
based upon the following parameters: mismatch penalty of 1; gap
penalty of 1; gap size penalty of 0.33; and joining penalty of 30,
"Current Methods in Sequence Comparison and Analysis,"
Macromolecule Sequencing and Synthesis, Selected Methods and
Applications, pp 127-149 (1988), Alan R. Liss, Inc, all of which
are incorporated by reference.
[0103] An example of a useful algorithm is PILEUP. PILEUP creates a
multiple sequence alignment from a group of related sequences using
progressive, pair wise alignments. It may also plot a tree showing
the clustering relationships used to create the alignment. PILEUP
uses a simplification of the progressive alignment method of Feng
& Doolittle, J. Mol. Evol. 35:351-360 (1987); the method is
similar to that described by Higgins & Sharp CABIOS 5:151-153
(1989), both incorporated by reference. Useful PILEUP parameters
including a default gap weight of 3.00, a default gap length weight
of 0.10, and weighted end gaps.
[0104] Another example of a useful algorithm is the BLAST
algorithm, described in: Altschul et al., J. Mol. Biol. 215,
403-410, (1990); Altschul et al., Nucleic Acids Res. 25:3389-3402
(1997); and Karlin et al., Proc. Natl. Acad. Sci. U.S.A.
90:5873-5787 (1993), both incorporated by reference. A particularly
useful BLAST program is the WU-BLAST-2 program which was obtained
from Altschul et al., Methods in Enzymology, 266:460-480 (1996);
http://blast.wustl/edu/blast/ README.html]. WU-BLAST-2 uses several
search parameters, most of which are set to the default values. The
adjustable parameters are set with the following values: overlap
span=1, overlap fraction=0.125, word threshold (T)=11. The HSP S
and HSP S2 parameters are dynamic values and are established by the
program itself depending upon the composition of the particular
sequence and composition of the particular database against which
the sequence of interest is being searched; however, the values may
be adjusted to increase sensitivity.
[0105] An additional useful algorithm is gapped BLAST, as reported
by Altschul et al., Nucl. Acids Res., 25:3389-3402, incorporated by
reference. Gapped BLAST uses BLOSUM-62 substitution scores;
threshold T parameter set to 9; the two-hit method to trigger
ungapped extensions; charges gap lengths of k a cost of 10+k; Xu
set to 16, and Xg set to 40 for database search stage and to 67 for
the output stage of the algorithms. Gapped alignments are triggered
by a score corresponding to .about.22 bits.
[0106] A % amino acid sequence identity value is determined by the
number of matching identical residues divided by the total number
of residues of the "longer" sequence in the aligned region. The
"longer" sequence is the one having the most actual residues in the
aligned region (gaps introduced by WU-Blast-2 to maximize the
alignment score are ignored). In a similar manner, "percent (%)
nucleic acid sequence identity" with respect to the coding sequence
of the polypeptides identified is defined as the percentage of
nucleotide residues in a candidate sequence that are identical with
the nucleotide residues in the coding sequence of the cell cycle
protein. A preferred method utilizes the BLASTN module of
WU-BLAST-2 set to the default parameters, with overlap span and
overlap fraction set to 1 and 0.125, respectively.
[0107] The alignment may include the introduction of gaps in the
sequences to be aligned. In addition, for sequences which contain
either more or fewer amino acids than the protein encoded by the
wild-type Factor IX sequence of FIG. 3A (SEQ ID NO: 2), it is
understood that in one embodiment, the percentage of sequence
identity will be determined based on the number of identical amino
acids or nucleotides in relation to the total number of amino acids
or nucleotides. Thus, for example, sequence identity of sequences
shorter than that shown in FIG. 3A (SEQ ID NO: 2), as discussed
below, will be determined using the number of nucleotides in the
shorter sequence, in one embodiment. In percent identity
calculations relative weight is not assigned to various
manifestations of sequence variation, such as, insertions,
deletions, substitutions, etc.
[0108] In one embodiment, only identities are scored positively
(+1) and all forms of sequence variation including gaps are
assigned a value of "0", which obviates the need for a weighted
scale or parameters as described below for sequence similarity
calculations. Percent sequence identity may be calculated, for
example, by dividing the number of matching identical residues by
the total number of residues of the "shorter" sequence in the
aligned region and multiplying by 100. The "longer" sequence is the
one having the most actual residues in the aligned region.
[0109] The term "allelic variants" refers to polymorphic forms of a
gene at a particular genetic locus, as well as cDNAs derived from
mRNA transcripts of the genes, and the polypeptides encoded by
them. The term "preferred mammalian codon" refers a subset of
codons from among the set of codons encoding an amino acid that are
most frequently used in proteins expressed in mammalian cells as
chosen from the following list: Gly (GGC, GGG); Glu (GAG); Asp
(GAC); Val (GTG, GTC); Ala (GCC, GCT); Ser (AGC, TCC); Lys (AAG);
Asn (AAC); Met (ATG); Ile (ATC); Thr (ACC); Trp (TGG); Cys (TGC);
Tyr (TAT, TAC); Leu (CTG); Phe (TTC); Arg (CGC, AGG, AGA); Gln
(CAG); His (CAC); and Pro (CCC).
[0110] As used herein, the term codon-altered refers to a
polynucleotide sequence encoding a polypeptide (e.g., a Factor IX
protein), where at least one codon of the native polynucleotide
encoding the polypeptide has been changed to improve a property of
the polynucleotide sequence. In some embodiments, the improved
property promotes increased transcription of mRNA coding for the
polypeptide, increased stability of the mRNA (e.g., improved mRNA
half-life), increased translation of the polypeptide, and/or
increased packaging of the polynucleotide within the vector.
Non-limiting examples of alterations that can be used to achieve
the improved properties include changing the usage and/or
distribution of codons for particular amino acids, adjusting global
and/or local GC content, removing AT-rich sequences, removing
repeated sequence elements, adjusting global and/or local CpG
dinucleotide content, removing cryptic regulatory elements (e.g.,
TATA box and CCAAT box elements), removing of intron/exon splice
sites, improving regulatory sequences (e.g., introduction of a
Kozak consensus sequence), and removing sequence elements capable
of forming secondary structure (e.g., stem-loops) in the
transcribed mRNA.
[0111] As discussed herein, there are various nomenclatures to
refer to components of the disclosure herein. "CS-number" (e.g.
"CS02," "CS03," "CS04," "CS05," "CS06," etc.) refer to codon
altered polynucleotides encoding FIX polypeptides and/or the
encoded polypeptides, including variants. For example, CS02-FL
refers to the Full Length codon altered CS02 polynucleotide
sequence or amino acid sequence (sometimes referred to herein as
"CS02-FL-AA" for the Amino Acid sequence and "CS02-FL-NA" (SEQ ID
NO: 5) for the Nucleic Acid sequence) encoded by the CS02
polynucleotide sequence. Similarly, "CS02-LC" refers to either the
codon altered nucleic acid sequence ("CS02-LC-NA" (SEQ ID NO: 42))
encoding the light chain of a FIX polypeptide or the amino acid
sequence (also sometimes referred to herein as "CS02-LC-AA") of the
FIX light chain encoded by the CS02 polynucleotide sequence.
Likewise, CS02-HC, CS02-HC-AA, and CS02-HC-NA (SEQ ID NO: 41) are
the same for the FIX heavy chain. As will be appreciated by those
in the art, for constructs such as CS02, CS03, CS04, CS05, CS06,
etc., that are only codon-altered (e.g. they do not contain
additional amino acid substitutions as compared to the Padua Factor
IX variant), the amino acid sequences will be identical, as the
amino acid sequences are not altered by the codon optimization.
Thus, sequence constructs of the disclosure include, but are not
limited to, CS02-FL-NA (SEQ ID NO: 5), CS02-FL-AA, CS02-LC-NA (SEQ
ID NO: 42), CS02-LC-AA, CS02-HC-AA, CS02-HC-NA (SEQ ID NO: 41),
CS03-FL-NA (SEQ ID NO: 6), CS03-FL-AA, CS03-LC-NA (SEQ ID NO: 44),
CS03-LC-AA, CS03-HC-AA, CS03-HC-NA (SEQ ID NO: 43), CS04-FL-NA (SEQ
ID NO: 7), CS04-FL-AA, CS04-LC-NA (SEQ ID NO: 46), CS04-LC-AA,
CS04-HC-AA, CS04-HC-NA, CS05-FL-NA (SEQ ID NO: 8), CS05-FL-AA,
CS05-LC-NA (SEQ ID NO: 48), CS05-LC-AA, CS05-HC-AA, CS05-HC-NA (SEQ
ID NO: 47), CS06-FL-NA (SEQ ID NO: 9), CS06-FL-AA, CS06-LC-NA (SEQ
ID NO: 50), CS06-LC-AA, CS06-HC-AA, and CS06-HC-NA (SEQ ID NO: 49).
It should be noted that all "CS" constructs herein encode or
contain the FIXp amino acid sequence, although included within the
definition of CS constructs are those that encode or contain the
human wild type FIX amino acid sequence.
[0112] As used herein, the term "liver-specific expression" refers
to the preferential or predominant in vivo expression of a
particular gene (e.g., a codon-altered, transgenic Factor IX gene)
in hepatic tissue, as compared to in other tissues. In some
embodiments, liver-specific expression means that at least 50% of
all expression of the particular gene occurs within hepatic tissues
of a subject. In other embodiments, liver-specific expression means
that at least 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, 99%, or
100% of all expression of the particular gene occurs within hepatic
tissues of a subject. Accordingly, a liver-specific regulatory

III. Codon-Altered Factor IX Polynucleotides
[0118] In some embodiments, the present disclosure provides codon
altered nucleic acid compositions encoding Factor IX or a Factor IX
variant (with FIXp finding use in particular embodiments). These
codon-altered polynucleotides provide markedly improved expression
of Factor IX when administered in an AAV-based gene therapy
construct. The codon-altered polynucleotides also demonstrate
improved AAV-virion packaging, as compared to conventionally
codon-optimized constructs. As demonstrated in Example 1,
Applicants have achieve these advantages through the discovery of
several codon-altered polynucleotides (e.g., CS02-FL-NA,
CS03-FL-NA, CS04-FL-NA, CS05-FL-NA, and CS06-FL-NA (SEQ ID NOS:5-9
respectively)) encoding a Factor IXp polypeptides with a
hyperactive R338L amino acid substitution (based on the mature,
single-chain Factor IX polypeptide sequence; R384L based on the
Factor IX pre-pro-protein sequence). As demonstrated in Examples 2
and 3, incorporation of one or more liver-specific regulatory
control element (e.g., CRM8) into gene therapy vectors encoding the
Factor IX molecule further increased in vivo and in vitro
expression of Factor IX and Factor IX activity.
[0119] Wild-type Factor IX is encoded with a 28 amino acid signal
peptide (FIX-SP-AA (SEQ ID NO: 37)) and an 18 amino acid
pro-peptide (FIX-PP-AA (SEQ ID NO: 38)), which are cleaved from the
encoded polypeptide prior to activation of Factor IXa. As
appreciated by those in the art, signal peptides and/or
pro-peptides may be mutated, replaced by signal peptides and/or
pro-peptides from other genes or other organisms, or completely
removed, without affecting the sequence of the mature polypeptide
left after the signal and pro-peptide are removed by cellular
processing.
[0120] Accordingly, in some embodiments, a codon-altered
polynucleotide (e.g., a nucleic acid composition) provided herein
has a nucleotide sequence with high sequence identity to
CS02-FL-NA, CS03-FL-NA, CS04-FL-NA, CS05-FL-NA, or CS06-FL-NA (SEQ
ID NOS:5-9, respectively) encoding the mature Factor IX
single-chain polypeptide, that is, the Factor IX light chain,
activation peptide, and heavy chain (e.g., amino acids 47-461 of
the full-length polypeptide encoded by the wild-type Factor IX
gene; FIX-FL-AA (SEQ ID NO: 2)).
[0121] Additionally, as known in the art, human wild type Factor IX
has a 34 amino acid activation peptide positioned between the
Factor IX light chain and heavy chain that is excised from the
single-chain Factor IX polypeptide upon activation of the protein.
Because the activation peptide is removed from the active Factor IX
polypeptide, the peptide itself is dispensable for ultimate Factor
IX activity. Accordingly, it is not required that the Factor IX
polypeptides encoded by the codon-altered polynucleotides disclosed
herein have high sequence identity to the human wild type
activation peptide sequence (FIX-AP-AA (SEQ ID NO: 56)). However,
the encoded activation peptide should be excisable upon activation
of the Factor IX polypeptide. For example, in some embodiments, the
encoded activation peptide should include Factor XI cleavage sites
at its N- and C-termini, that are recognizable and cleavable by
human Factor IX in-vivo.
[0122] Accordingly, in some embodiments, a codon-altered
polynucleotide (e.g., a nucleic acid composition) provided herein
encodes for a single-chain Factor IX polypeptide with high sequence
identity to the human wild type FIX light chain sequence (FIX-LC-AA
(SEQ ID NO: 62)) and human wild type FIX heavy chain sequence
(FIX-HC-AA (SEQ ID NO: 63)), and additionally encode for a
polypeptide linker joining the C-terminus of the light chain to the
N-terminus of the heavy chain (e.g., an activation peptide) with
two Factor XI cleavage sites.
[0123] In some embodiments, the Factor IX light and heavy chains
encoded by the codon-altered polynucleotide are human Factor IX
light and heavy chains, respectively, including the FIXp heavy
chain. In other embodiments, the Factor IX light and heavy chains
encoded by the codon-altered polynucleotide are heavy and light
chain sequences from another mammal (e.g., porcine Factor IX). In
yet other embodiments, the Factor IX light and heavy chains are
chimeric light and heavy chains (e.g., a combination of human and a
second mammalian sequence). In yet other embodiments, the Factor IX
light and heavy chains are humanized version of the light and heavy
chains from another mammal, e.g., light and heavy chain sequences
from another mammal in which human residues are substituted at
select positions to reduce the immunogenicity of the resulting
peptide when administered to a human.
[0124] The GC content of human genes varies widely, from less than
25% to greater than 90%. However, in general, human genes with
higher GC contents are expressed at higher levels. For example,
Kudla et al. (PLoS Biol., 4(6):80 (2006)) demonstrate that
increasing a gene's GC content increases expression of the encoded
polypeptide, primarily by increasing transcription and effecting a
higher steady state level of the mRNA transcript. Generally, the
desired GC content of a codon-optimized gene construct is thought
to be equal or greater than 60%. For example, the Factor IX gene in
the scAAV8.FIXR338L gene therapy vector was specifically codon
altered, using the GeneOptimizer software (Geneart), to increase
the GC content of the wild type coding sequence from 41% GC to 61%
GC. See, Wu Z. et al., Mol Ther 16:280-89 (2008) and Monahan PE et
al., Hum Gene Ther., 26(2):69-81 (2015). However, native AAV
genomes have GC contents of around 56%.
[0125] Accordingly, in some embodiments, the codon-altered
polynucleotides (e.g., nucleic acid compositions) provided herein
have a CG content that more closely matches the GC content of
native AAV virions (e.g., around 56% GC), which is lower than the
preferred CG contents of polynucleotides that are conventionally
codon-optimized for expression in mammalian cells (e.g., at or
above 60% GC). For example, CS02-FL-NA (SEQ ID NO: 5) has a GC
content of about 54%, CS03-FL-NA (SEQ ID NO: 6) has a GC content of
about 55%, CS04-FL-NA (SEQ ID NO: 7) has a GC content of about
54.5%, CS05-FL-NA (SEQ ID NO: 8) has a GC content of about 56.6%,
and CS06-FL-NA (SEQ ID NO: 9) has a GC content of about 55%. These
constructs should provide has improved virion packaging as compared
to similarly codon-altered sequences with higher GC content.
[0126] Thus, in some embodiments, the overall GC content of a
codon-altered polynucleotide encoding a Factor IX polypeptide
(e.g., a polynucleotide having high sequence identity to one of the
CS02-C S06 Factor IX coding sequences) is less than 60%. In some
embodiments, the overall GC content of a codon-altered
polynucleotide encoding a Factor IX polypeptide is less than 59%.
In some embodiments, the overall GC content of a codon-altered

[0131] It has been theorized that these CpG dinucleotides (i.e., a
cytosine nucleotide followed by a guanine nucleotide) induce immune
responses via toll-like receptors, in vivo. Some evidence suggests
that CpG-depleted AAV vectors evade immune detection in mice, under
certain circumstances (Faust et al., J. Clin. Invest. 2013; 123,
2994-3001). The wild type Factor IX coding sequence (FIX-FL-NA (SEQ
ID NO: 1)) contains 20 CpG dinucleotides.
[0132] Accordingly, in some embodiments, the nucleic acid
compositions (e.g., codon-altered polynucleotides) provided herein
are codon-altered to reduce the number of CpG dinucleotides in the
Factor IX coding sequence. For example, CS02-FL-NA (SEQ ID NO: 5)
has no CpG dinucleotides, CS03-FL-NA (SEQ ID NO: 6) has no CpG
dinucleotides, CS04-FL-NA (SEQ ID NO: 7) has no CpG dinucleotides,
CS05-FL-NA (SEQ ID NO: 8) has 11 CpG dinucleotides, and CS06-FL-NA
(SEQ ID NO: 9) has 3 CpG dinucleotides. These constructs should
illicit lower immunogenic responses than the wild type Factor IX
coding sequence and similarly codon-altered sequences with higher
numbers of CpG dinucleotides.
[0133] Thus, in some embodiments, a sequence of a codon-altered
polynucleotide encoding a Factor IX polypeptide (e.g., a
polynucleotide having high sequence identity to one of the
CS02-CS06 Factor IX coding sequences) has less than 20 CpG
dinucleotides. In some embodiments, a sequence of a codon-altered
polynucleotide encoding a Factor IX polypeptide has less than 15
CpG dinucleotides. In some embodiments, a sequence of a
codon-altered polynucleotide encoding a Factor IX polypeptide has
less than 12 CpG dinucleotides. In some embodiments, a sequence of
a codon-altered polynucleotide encoding a Factor IX polypeptide has
less than 10 CpG dinucleotides. In some embodiments, a sequence of
a codon-altered polynucleotide encoding a Factor IX polypeptide has
less than 5 CpG dinucleotides. In some embodiments, a sequence of a
codon-altered polynucleotide encoding a Factor IX polypeptide has
less than 3 CpG dinucleotides. In some embodiments, a sequence of a
codon-altered polynucleotide encoding a Factor IX polypeptide has
no CpG dinucleotides.
[0134] In some embodiments, a sequence of a codon-altered
polynucleotide encoding a Factor IX polypeptide has more than 15
CpG dinucleotides. In some embodiments, a sequence of a
codon-altered polynucleotide encoding a Factor IX polypeptide has
no more than 12 CpG dinucleotides. In some embodiments, a sequence
of a codon-altered polynucleotide encoding a Factor IX polypeptide
has no more than 10 CpG dinucleotides. In some embodiments, a
sequence of a codon-altered polynucleotide encoding a Factor IX
polypeptide has no more than 5 CpG dinucleotides. In some
embodiments, a sequence of a codon-altered polynucleotide encoding
a Factor IX polypeptide has no more than 3 CpG dinucleotides. In
some embodiments, a sequence of a codon-altered polynucleotide
encoding a Factor IX polypeptide has no CpG dinucleotides. In some
embodiments, sequence of a codon-altered polynucleotide encoding a
Factor IX polypeptide has no more than 18, 17, 16, 15, 14, 13, 12,
11, 10, 9, 8, 7, 6, 5, 4, 3, 2, 1, or no CpG dinucleotides.
[0135] A. Factor IX Amino Acid Substitutions
[0136] To further increase the efficiency of AAV-vector based
expression of the Factor IX constructs described herein, amino acid
substitutions know to improve secretion, increase specific
activity, and/or enhanced the stability of Factor IX are further
incorporated, in accordance with some implementations. A number of
potential Factor IX variants are known in the art to increase the
plasma levels of FIX activity. These variants include amino acid
substitutions that increase Factor IX catalytic activity (e.g.,
hyperactive mutants), increase resistance to antithrombin III
and/or heparin, increase serum half-life, and result in altered
patterns of post-translational modification.
[0137] For example, mutation of residue R338 (PPE) can increase the
clotting activity of Factor IX. For review, see U.S. Pat. No.
6,531,298, the contents of which are hereby incorporated by
reference in its entirety for all purposes. As disclosed in U.S.
Pat. No. 6,531,298, an arginine to leucine amino acid substitution
at this position increases the activity of Factor IX. This was
later confirmed in vivo, where the R338L (PPE) mutation increases
Factor IX activity 5-fold to 10-fold in vivo. For review, see
Simioni P. et al., N Engl J Med. 361(17):1671-75 (2009), hereby
incorporated by reference in its entirety. Accordingly, in some
embodiments, the codon-altered polynucleotides described herein
encode a Factor IX polypeptide with an amino acid substitution at
arginine 384 (PPI; residue 338 (PPE). In a specific embodiment, the
amino acid substitution is R384L (PPI). In other embodiments, the
amino acid substitution at residue 384 (PPI)/338 (PPE) to a residue
other than leucine. For example, it was reported that an R384A
(PPI) amino acid substitution provided 2-for to 6-fold higher
activity in mice. Schuettrumpf J et al., Blood, 105(6):2316-23
(2005), the content of which is expressly incorporated herein by
reference, in its entirety, for all purposes.
[0138] Similarly, mutation of residues Y305, K311, 5365, and Y391
leads to increased Factor IX activity on a synthetic substrate. In
particular, K311M and K311T single mutations resulted in 2.8-fold
and 6.7-fold increased activity on a synthetic cleavage substrate.
Sichler K. et al., J Biol Chem. 278(6):4121-26 (2003) (using
different residue numbering). Further, a Y305F/K311T/Y391T triple
mutant resulted in 7000-fold increased activity on the synthetic
substrate. Id. Accordingly, in some embodiments, the codon-altered
polynucleotides described herein encode a Factor IX polypeptide
with an amino acid substitution at one or more of tyrosine 305
(PPI), lysine 311 (PPI), and tyrosine 391 (PPI). In a specific
embodiment, the amino acid substitution is K311M (PPI). In a
specific embodiment, the amino acid substitution is K311T (PPI). In
another specific embodiment, the amino acid substitution is
Y305F/K311T/Y391T (PPI).
[0139] Other amino acid substitutions that provide improved
properties are known in the art and may be incorporated into the
described codon-altered Factor IX polynucleotides. For example,
see, U.S. Pat. No. 8,778,870, the content of which is expressly
incorporated herein by reference, in its entirety, for all
purposes.

herein includes a Factor IX polynucleotide (e.g., a codon-optimized

IV. FACTOR IX EXPRESSION VECTORS
[0329] In some embodiments, the codon-altered polynucleotides
described herein are integrated into expression vectors. As will be
appreciated by one of skill in the art, many forms of vectors can
be used to effectuate Factor IX gene therapy using the
codon-altered Factor IX polynucleotide sequences disclosed herein.
Non-limiting examples of expression vectors include viral vectors
(e.g., vectors suitable for gene therapy), plasmid vectors,
bacteriophage vectors, cosmids, phagemids, artificial chromosomes,
and the like.
[0330] In some embodiments, the codon-altered polynucleotides
described herein are integrated into a viral gene therapy vector.
Non-limiting examples of viral vectors include: retrovirus, e.g.,
Moloney murine leukemia virus (MMLV), Harvey murine sarcoma virus,
murine mammary tumor virus, and Rous sarcoma virus; adenoviruses,
adeno-associated viruses; SV40-type viruses; polyomaviruses;
Epstein-Barr viruses; papilloma viruses; herpes viruses; vaccinia
viruses; and polio viruses.
[0331] In vivo, Factor IX is synthesized primarily in the liver. As
such, hepatocytes have been targeted as suitable host cells for
Factor IX gene therapy constructs. Several classes of viral vectors
have been shown competent for liver-targeted delivery of a gene
therapy construct, including retroviral vectors (see, e.g., Axelrod
et al., 1990; Kay et al., 1992; Van den Driessche et al., 1999, and
Xu et al., 2003, 2005, the disclosures of which are hereby
expressly incorporated by reference, in their entireties, for all
purposes), lentiviral (see, e.g., Ward et al., 2011, Brown et al.,
2007, and Matrai et al., 2011, the disclosures of which are hereby
expressly incorporated by reference, in their entireties, for all
purposes), adeno-associated viral (AAV) (see, e.g., Herzog et al.,
1999, the disclosure of which is hereby expressly incorporated by
reference, in its entirety, for all purposes), and adenoviral
vectors (see, e.g., Brown et al., 2004 and Ehrhardt & Kay,
2002, the disclosures of which are hereby expressly incorporated by
reference, in their entireties, for all purposes).
[0332] In some embodiments, the gene therapy vector is a
retrovirus, and particularly a replication-deficient retrovirus.
Protocols for the production of replication-deficient retroviruses
are known in the art. For review, see Kriegler, M., Gene Transfer
and Expression, A Laboratory Manual, W.H. Freeman Co., New York
(1990) and Murry, E. J., Methods in Molecular Biology, Vol. 7,
Humana Press, Inc., Cliffton, N.J. (1991).
[0333] In one embodiment, the gene therapy vector is an
adeno-associated virus (AAV) based gene therapy vector. AAV systems
have been described previously and are generally well known in the
art (Kelleher and Vos, Biotechniques, 17(6):1110-17 (1994); Cotten
et al., P.N.A.S. U.S.A., 89(13):6094-98 (1992); Curiel, Nat Immun,
13(2-3):141-64 (1994); Muzyczka, Curr Top Microbiol Immunol,
158:97-129 (1992); and Asokan A, et al., Mol. Ther., 20(4):699-708
(2012), each incorporated herein by reference in their entireties
for all purposes). Details concerning the generation and use of
rAAV vectors are described, for example, in U.S. Pat. Nos.
5,139,941 and 4,797,368, each incorporated herein by reference in
their entireties for all purposes. In a particular embodiment, the
AAV vector is an AAV-8 vector.
[0334] An exemplary AAV delivery vector for liver-specific Factor
IX expression is described in WO 2009/130208, the content of which
is expressly incorporated by reference herein, in its entirety, for
all purposes. The vector is a single-stranded AAV vector encoding
human Factor IX, and includes TTR Serp regulatory sequences driving
a factor cDNA. The vector also includes intron I of the human
Factor IX gene and a poly-adenylation signal.
[0335] In some embodiments, the codon-altered polynucleotides
described herein are integrated into a retroviral expression
vector. These systems have been described previously, and are
generally well known in the art (Mann et al., Cell, 33:153-159,
1983; Nicolas and Rubinstein, In: Vectors: A survey of molecular
cloning vectors and their uses, Rodriguez and Denhardt, eds.,
Stoneham: Butterworth, pp. 494-513, 1988; Temin, In: Gene Transfer,
Kucherlapati (ed.), New York: Plenum Press, pp. 149-188, 1986). In
a specific embodiment, the retroviral vector is a lentiviral vector
(see, for example, Naldini et al., Science, 272(5259):263-267,
1996; Zufferey et al., Nat Biotechnol, 15(9):871-875, 1997; Blomer
et al., J Virol., 71(9):6641-6649, 1997; U.S. Pat. Nos. 6,013,516
and 5,994,136).
[0336] In some embodiments, the codon-altered polynucleotides
described herein can be administered to a subject by a non-viral
method. For example, naked DNA can be administered into a cell by
electroporation, sonoporation, particle bombarment, or hydrodyamic
delivery. DNA can also be encapsulated or coupled with polymers,
e.g., liposomes, polysomes, polypleses, dendrimers, and
administered to the subject as a complex. Likewise, DNA can be
coupled to inorganic nanoparticles, e.g., gold, silica, iron oxide,
or calcium phosphate particles, or attached to cell-penetrating
peptides for delivery to cells in vivo.
[0337] Codon-altered Factor IX coding polynucleotides can also be
incorporated into artificial chromosomes, such as Artificial
Chromosome Expression (ACEs) (see, e.g., Lindenbaum et al., Nucleic
Acids Res., 32(21):e172 (2004)) and mammalian artificial
chromosomes (MACs). For review see, e.g., Perez-Luz and Diaz-Nido,
J Biomed Biotechnol. 2010: Article ID 642804 (2010).
[0338] A wide variety of vectors can be used for the expression of
a Factor IX polypeptide from a codon-altered polypeptide in cell
culture, including eukaryotic and prokaryotic expression vectors.
In certain embodiments, a plasmid vector is contemplated for use in
expressing a Factor IX polypeptide in cell culture. In general,
plasmid vectors containing replicon and control sequences which are
derived from species compatible with the host cell are used in
connection with these hosts. The vector can carry a replication
site, as well as marking sequences which are capable of providing
phenotypic selection in transformed cells. The plasmid will include
the codon-altered polynucleotide encoding the Factor IX
polypeptide, operably linked to one or more control sequences, for
example, a promoter.
[0339] Non-limiting examples of vectors for prokaryotic expression
include plasmids such as pRSET, pET, pBAD, etc., wherein the
promoters used in prokaryotic expression vectors include lac, trc,
trp, recA, araBAD, etc. Examples of vectors for eukaryotic
expression include: (i) for expression in yeast, vectors such as
pAO, pPIC, pYES, pMET, using promoters such as AOX1, GAP, GAL1,
AUG1, etc; (ii) for expression in insect cells, vectors such as
pMT, pAc5, pIB, pMIB, pBAC, etc., using promoters such as PH, p10,
MT, Ac5, OpIE2, gp64, polh, etc., and (iii) for expression in
mammalian cells, vectors such as pSVL, pCMV, pRc/RSV, pcDNA3, pBPV,
etc., and vectors derived from viral systems such as vaccinia
virus, adeno-associated viruses, herpes viruses, retroviruses,
etc., using promoters such as CMV, SV40, EF-1, UbC, RSV, ADV, BPV,
and .beta.-actin.
[0340] In some embodiments, the disclosure provides an AAV gene
therapy vector that includes a codon-altered Factor IX
polynucleotide, as described herein, internal terminal repeat (ITR)
sequences on the 5' and 3' ends of the vector, one or more promoter
and/or enhancer sequences operably-linked to the Factor IX
polynucleotide, and a poly-adenylation signal following the 3' end
of the Factor IX polynucleotide sequence. In some embodiments, the
one or more promoter and/or enhancer sequences include one or more
copies of a liver-specific regulatory control element.
[0341] FIG. 1 illustrates several exemplary architectures for a
Factor IX gene therapy vector, in accordance with some
implementations. FIG. 1A illustrates a self-complementary AAV
vector having a mutated 5' ITR, truncated TTR enhancer/promoter
sequences, an MVM viral intron sequence, a codon-altered Factor IX
coding sequence, a poly-adenylation sequence, and a 3' -ITR. FIG.
1B illustrates a self-complementary AAV vector encoding a Factor IX
polypeptide similar to FIG. 1A, but further including one or more
(e.g., one, two, three, or more) liver-specific regulatory control
elements. FIG. 1C illustrates a single-stranded vector having the
same elements as FIG. 1A, except that the 5' -ITR is not mutated,
preventing self-complementarity. FIG. 1D illustrates a
single-stranded AAV vector encoding a Factor IX polypeptide similar
to FIG. 1A, but further including one or more (e.g., one, two,
three, or more) liver-specific regulatory control elements.
Although illustrated with reference to a Factor IX protein that
includes an R384L `Padua` amino acid substitution in FIG. 1, in
some embodiments, a Factor IX nucleotide construct having a general
structure as depicted in FIG. 1 (e.g., structure A, B, C, or D)
encodes a Factor IX protein that does not include an R384L `Padua`
amino acid substitution.
[0342] FIG. 25 shows the nucleotide sequence of an AAV Factor IX
gene therapy vector CS06-CRM8.3-ssV (SEQ ID NO: 40), which
exemplifies the gene therapy vector architecture illustrated in
FIG. 1D. Nucleotides 1-145 of CS06-CRM8.3-ssV (SEQ ID NO: 40) is an
AAV2 5' -ITR sequence (SEQ ID NO: 51). The 5' -ITR sequence is
followed by three copies of a liver-specific CRM8 regulatory
control element CRM8 (SEQ ID NO: 39) at nucleotides 165-236,
238-309, and 311-382. Following the CRM8 sequence is a truncated
TTR enhancer/promoter sequence (SEQ ID NO: 52) at nucleotides
383-712. Next, the vector includes a minute virus of mice (MVM)
intron (SEQ ID NO: 53) at nucleotides 724-800. Nucleotides 814-2199
of the vector are a CS06 codon-altered Factor IX(R384L) coding
sequence (CS06-FL-NA (SEQ ID NO: 9)). The Factor IX polynucleotide
sequence is followed by a BGH poly-adenylation signal at
nucleotides 2208-2441 and, finally, an AAV2 3' -ITR sequence (SEQ
ID NO: 55) at nucleotides 2458-2602.
[0343] In some embodiments, the disclosure provides a Factor IX
polynucleotide comprising a sequence having at least 95% identity
to nucleotides 1-2602 of SEQ ID NO: 40. In some embodiments, the
disclosure provides a Factor IX polynucleotide comprising a
sequence having at least 99% identity to nucleotides 1-2602 of SEQ
ID NO: 40. In some embodiments, the disclosure provides a Factor IX
polynucleotide comprising a sequence having at least 99.5% identity
to nucleotides 1-2602 of SEQ ID NO: 40. In some embodiments, the
disclosure provides a Factor IX polynucleotide comprising the
sequence of nucleotides 1-2602 of SEQ ID NO: 40.
[0344] Several AAV serotypes have been characterized, including
AAV1, AAV2, AAV3, AAV4, AAVS, AAV6, AAV7, AAV8, and AAV9.
Generally, any AAV serotype may be used for the Factor IX gene
therapy constructs described herein. However, the serotypes have
different tropisms, e.g., they preferentially infect different
tissues. In one embodiment, because Factor IX is produced primarily
in the liver, an AAV serotype for the disclosed gene therapy
constructs is selected based on a liver tropism, found in at least
serotypes AAV7, AAV8, and AAV9. Accordingly, in one embodiment, a
Factor IX gene therapy construct is an AAV7 serotype vector. In
another embodiment, a Factor IX gene therapy construct is an AAV8
serotype vector. In yet another embodiment, a Factor IX gene
therapy construct is an AAV9 serotype vector.
[0345] The Factor IX gene therapy constructs described herein may
be single-stranded (e.g., a ssAAV vector, as illustrated in FIGS.
1C and 1D) or self-complementary (e.g., a scAAV vector, as
illustrated in FIGS. 1A and 1B). Although research and theory has
suggested that self-complementary AAV vectors should facilitate
better transgene expression, by bypassing the requirement for
second-strand synthesis prior to translation, single-stranded AAV
vectors promoting better Factor IX expression that comparable
self-complementary vector were identified, as reported in Example
5.
[0346] Promoters and Enhancers
[0347] The Factor IX gene therapy constructs described herein
generally include one or more promoter and/or enhancer element that
drives gene expression in vivo, e.g., a regulatory element. In some
embodiments, a promoter or enhancer element drives expression in a
tissue dependent fashion, e.g., predominantly in a specific tissue.
Because Factor IX is synthesized primarily in the liver, in some
embodiments, the gene therapy vectors described herein include a
liver-specific regulatory element, which substantially limit
expression of the gene therapy vector to hepatic cells.
[0348] Generally, liver-specific regulatory elements can be derived
from any gene known to be exclusively expressed in the liver. WO
2009/130208 identifies several genes expressed in a liver-specific
fashion, including, serpin peptidase inhibitor, Glade A member 1,
also known as .alpha.-antitrypsin (SERPINAl; GeneID 5265),
apolipoprotein C-I (APOC1; GeneID 341), apolipoprotein C-IV (APOC4;
GeneID 346), apolipoprotein H (APOH; GeneID 350); transthyretin
(TTR; GeneID 7276), albumin (ALB; GeneID 213), aldolase B (ALDOB;
GeneID 229), cytochrome P450, family 2, subfamily E, polypeptide 1
(CYP2E1; GeneID 1571), fibrinogen alpha chain (FGA; GeneID 2243),
transferrin (TF; GeneID 7018), haptoglobin related protein (HPR;
GeneID 3250). In some embodiments, the Factor IX gene therapy
constructs described herein include a liver-specific regulatory
element derived from the genomic loci of one or more of these
proteins. Several examples of such elements are described in WO
2009/130208, the content of which is expressly incorporated herein
by reference, in its entirety, for all purposes.
[0349] One example of a liver-specific regulatory element is from
the transthyretin (TTR) gene, commonly referred to as "TTRe" or
"TTREnh." Hsieh J.L., et al., Cancer Sci., 100(3):537-45 (2009),
the content of which is expressly incorporated herein by reference,
in its entirety, for all purposes. In some embodiments, the Factor
IX gene therapy constructs described herein include truncated TTR
enhancer and promoter elements. An example of these elements is
provided at nucleotides 383-712 of CS06-CRM8.3-ssV (SEQ ID NO: 40),
provided as FIG. 25. In some embodiments, a truncated TTR enhancer
and promoter element has at least 85% sequence identity to
nucleotides 383-712 of CS06-CRM8.3-ssV (SEQ ID NO: 40). In other
embodiments, the truncated TTR enhancer and promoter element have
at least 90%, 95%, 96%, 97%, 98%, 99%, 99.5%, or 100% sequence
identity to nucleotides 383-712 of CS06-CRM8.3-ssV (SEQ ID NO:
40).
[0350] Another example of a liver-specific regulatory element is
from the SERPINA1 gene, as described in PCT Publication No. WO
2016/146757, the content of which is expressly incorporated herein
by reference, in its entirety, for all purposes. An example of such
an element is the CRM8 regulatory control element (SEQ ID NO: 39)
provided at nucleotides 165-236 of CS06-CRM8.3-ssV (SEQ ID NO: 40).
In some embodiments, a SERPINA1-derived regulatory control element
has at least 85% sequence identity to CRM8 (SEQ ID NO: 39). In
other embodiments, the truncated SERPINA1-derived regulatory
control element has at least 90%, 95%, 96%, 97%, 98%, 99%, or 100%
sequence identity to CRM8 (SEQ ID NO: 39).
[0351] In some embodiments, a Factor IX gene therapy construct
includes one or more SERPINA1-derived regulatory control element,
as exemplified by the constructs illustrated in FIGS. 1B and 1D. In
one embodiment, a construct includes one SERPINAl-derived
regulatory control element (e.g., CRM8). In another embodiment, a
construct includes two SERPINA1-derived regulatory control elements
(e.g., CRM8). In another embodiment, a construct includes three
SERPINAl-derived regulatory control elemenst (e.g., CRM8). In yet
other embodiments, a construct includes 4, 5, 6, or more
SERPINAl-derived regulatory control elemenst (e.g., CRM8).
[0352] In one embodiment, a Factor IX gene therapy construct
includes one or more SERPINA1-derived regulatory control element
(e.g., CRM8) and a truncated TTR enhancer and promoter element, as
exemplified in FIGS. 1B, 1D, and 25.
[0353] Introns
[0354] In some embodiments, the Factor IX gene therapy constructs
described herein include an intron, e.g., a virally-derived intron,
to increase expression of the Factor IX gene. Suitable introns for
the expression of gene therapy constructs are known in the art.
Typically, the intron is positioned 5' of the transgene coding
sequence, as exemplified in the Factor IX constructs shown in FIG.
1 and FIG. 25. However, in some embodiments, the intron may be
positioned within the transgene coding sequence, e.g., at a natural
Factor IX intron junction or otherwise, or 3' of the transgene
coding sequence. Non-limiting examples of introns that can be used
in the Factor IX gene therapy constructs described herein include
introns derived from a Minute Virus of Mice (MVM) intron, a
beta-globin intron (betalVS-11), a Factor IX (FIX) intron A, a
Simian virus 40 (SV40) Small T intron, and a beta-actin intron.
[0355] In one embodiment, the Factor IX gene therapy constructs
described herein include an MVM-derived intron, e.g., as
illustrated in FIG. 1 and exemplified by the MVM intron (SEQ ID NO:
53) at nucleotides 724-800 of CS06-CRM8.3-ssV (SEQ ID NO: 40) in
FIG. 25. In some embodiments, an intron used in the gene therapy
constructs described herein has at least 85% sequence identity to
MVM (SEQ ID NO: 53). In other embodiments, an intron used in the
gene therapy constructs described herein has at least 90%, 95%,
96%, 97%, 98%, 99%, or 100% sequence identity to MVM (SEQ ID NO:
53).
[0356] Poly-Adenylation Signals
[0357] In some embodiments, the Factor IX gene therapy constructs
described herein include a poly-adenylation signal, e.g., as
illustrated in in FIG. 1. The poly-adenylation signal directs
synthesis of a poly-A tail on the 3' end of the mRNA transcript
generated from the Factor IX transgene. Accordingly, the
poly-adenylation signal is positioned 3' to the Factor IX coding
sequence. Non-limiting examples of poly-adenylation signals that
can be used in the Factor IX gene therapy constructs described
herein include poly-adenylation signals derived from a Simian virus
40 (SV40) late gene, a bovine growth hormone (BGH) polyadenylation
signal, and a minimal rabbit (3-globin (mRBG) gene.
[0358] In one embodiment, the Factor IX gene therapy constructs

NO: 54) at nucleotides 2208-2441 of CS06-CRM8.3-ssV (SEQ ID NO: 40)
in FIG. 25. In some embodiments, a poly-adenylation signal used in

99%, or 100% sequence identity to the BGHpA signal (SEQ ID NO:
54).
V. METHODS
[0359] Production
[0360] The codon-altered Factor IX polynucleotides and viral
vectors described herein (e.g., the nucleic acid compositions) are
produced according to conventional methods for nucleic acid
amplification and vector production. Two predominant platforms have
developed for large-scale production of recombinant AAV vectors.
The first platform is based on replication in mammalian cells,
while the second is based on replication in invertebrate cells. For
review, see, Kotin R. M., Hum. Mol. Genet., 20(R1):R2-6 (2011), the
content of which is expressly incorporated herein by reference, in
its entirety, for all purposes.
[0361] Accordingly, the disclosure provides methods for producing
an adeno-associated virus (AAV) particle. In some embodiments, the
methods include introducing a codon-altered Factor IX
polynucleotide construct having high nucleotide sequence identity
(e.g., at least 95%, 96%, 97%, 98%, 99%, 99.5%, 99.9%, or 100%) to
one of a CS02, CS03, CS04, CS05, or CS06 sequence, as described
herein, into a host cell where the polynucleotide construct is
competent for replication in the host cell.
[0362] In some embodiments, the host cell is a mammalian host cell
e.g., an HEK, CHO, or BHK cell. In a specific embodiment, the host
cell is an HEK 293 cell. In some embodiments, the host cell is an
invertebrate cell, e.g., an insect cell. In a specific embodiment,
the host cell is an SF9 cell.
[0363] Formulations
[0364] Compositions for use in treatment of bleeding disorders are
provided herein. Such compositions contain a therapeutically
effective amount of a codon-altered Factor IX polynucleotide, e.g.,
an AAV gene therapy vector including a codon-altered polynucleotide
encoding for Factor IX , as described herein. Therapeutically
effective amounts of the codon-altered FIX polynucleotide (e.g., an
AAV gene therapy vector including the codon-altered Factor IX
coding sequence) are mixed with a suitable pharmaceutical carrier
or vehicle for systemic, topical or local administration. Final
formulation of the codon-altered Factor IX polynucleotides
disclosed herein will be within the abilities of those skilled in
the art.
[0365] Dosages
[0366] The nucleic acid compositions of the invention are
administered to patients in need thereof. The amount or dose of the
therapeutic gene therapy agent administered depends on factors such
as the particular codon-altered FIX polynucleotide construct, the
delivery vector used, the severity of the disease, and the general
characteristics of the subject. The exact dose will depend on the
purpose of the treatment, and will be ascertainable by one skilled
in the art using known techniques (see, e.g., Lieberman,
Pharmaceutical Dosage Forms (vols. 1-3, 1992); Lloyd, The Art,
Science and Technology of Pharmaceutical Compounding (1999);
Pickar, Dosage Calculations (1999); and Remington: The Science and
Practice of Pharmacy, 20th Edition, 2003, Gennaro, Ed., Lippincott,
Williams & Wilkins). It is within the abilities of the skilled
physician to determine a particular dosage and dosing regimen for
treatment of a particular subject.
[0367] In some embodiments, a gene therapy vector (e.g., an AAV
gene therapy vector particle) having a codon-altered Factor IX
polynucleotide is administered intravenously at a therapeutically
effective dose to a subject in need thereof (e.g., a subject with
mild, moderate, or severe hemophilia B). In some embodiments, a
therapeutically effective dose is between about 2.times.10E11 and
2.times.10E14 vector genomes per kilogram body weight of the
subject. In a specific embodiment, a therapeutically effective dose
is between about 2.times.10E12 and 2.times.10E13 vector genomes per
kilogram body weight of the subject. In some embodiments, the
subject is administered about 2.times.10E11, 3.times.10E11,
4.times.10E11, 5.times.10E11, 6.times.10E11, 7.times.10E11,
8.times.10E11, 9.times.10E11, 1.times.10E12, 2.times.10E12,
3.times.10E12, 4.times.10E12, 5.times.10E12, 6.times.10E12,
7.times.10E12, 8.times.10E12, 9.times.10E12, 1.times.10E13,
2.times.10E13, 3.times.10E13, 4.times.10E13, 5.times.10E13,
6.times.10E13, 7.times.10E13, 8.times.10E13, 9.times.10E13,
1.times.10E14, or 2.times.10E14 vector genomes per kilogram body
weight of the subject.
[0368] Accordingly, the disclosure provides methods for treating a
Factor IX deficiency (e.g., hemophilia B). In some embodiments, the
methods include administering to a patient in need thereof a
codon-altered Factor IX polynucleotide construct having high
nucleotide sequence identity (e.g., at least 95%, 96%, 97%, 98%,
99%, 99.5%, 99.9%, or 100%) to one of a CS02, CS03, CS04, CS05, or
CS06 sequence, as described herein. In some embodiments, the
codon-altered Factor polynucleotide has high sequence identity to a
codon-altered Factor IX pre-pro-polypeptide coding sequence, e.g.,
high sequence identity to one of CS02-FL-NA (SEQ ID NO: 5),
CS03-FL-NA (SEQ ID NO: 6), CS04-FL-NA (SEQ ID NO: 7), CS05-FL-NA
(SEQ ID NO: 8), or CS06-FL-NA (SEQ ID NO: 9). In some embodiments,
the codon-altered Factor polynucleotide has high sequence identity
to a codon-altered mature Factor IX single-chain polypeptide coding
sequence, e.g., high sequence identity to one of CS02-MP-NA (SEQ ID
NO: 13), CS03-MP-NA (SEQ ID NO: 14), CS04-MP-NA (SEQ ID NO: 15),
CS05-MP-NA (SEQ ID NO: 16), or CS06-MP-NA (SEQ ID NO: 17).
[0369] In some embodiments, treatment includes administering to a
patient in need thereof a gene therapy vector including a
codon-altered Factor IX polynucleotide construct having high
nucleotide sequence identity (e.g., at least 95%, 96%, 97%, 98%,
99%, 99.5%, 99.9%, or 100%) to one of a CS02, CS03, CS04, CS05, or
CS06 sequence, as described herein. In one embodiment, the gene
therapy vector is a mammalian gene therapy vector. In a specific
embodiment, the mammalian gene therapy vector is a viral vector,
e.g., a lentivirus, retrovirus, adeno virus, or adeno-associated
virus vector.
[0370] In one embodiment, the gene therapy vector is an
adeno-associated virus (AAV) particle harboring a viral vector
encoding the codon-altered Factor IX coding sequence. Generally,
the viral vector includes inverted terminal repeats (ITR) at each
termini, one or more expression regulatory elements, a
codon-altered Factor IX coding sequence, and a poly-A signal
sequence. In a specific embodiment, the gene therapy vector
includes a liver-specific regulatory control element (e.g., one or
more copies of a CRM8 element).
[0371] Production
[0372] The codon-altered Factor IX polynucleotides and viral
vectors described herein (e.g., the nucleic acid compositions) are
produced according to conventional methods for nucleic acid
amplification and vector production. Two predominant platforms have
developed for large-scale production of recombinant AAV vectors.
The first platform is based on replication in mammalian cells,
while the second is based on replication in invertebrate cells. For
review, see, Kotin R. M., Hum. Mol. Genet., 20(R1):R2-6 (2011), the
content of which is expressly incorporated herein by reference, in

[0373] Accordingly, the disclosure provides methods for producing
an adeno-associated virus (AAV) particle. In some embodiments, the
methods include introducing a codon-altered Factor IX
polynucleotide construct having high nucleotide sequence identity
(e.g., at least 95%, 96%, 97%, 98%, 99%, 99.5%, 99.9%, or 100%) to
one of a CS02, CS03, CS04, CS05, or CS06 sequence, as described
herein, into a host cell where the polynucleotide construct is
competent for replication in the host cell.
[0374] In some embodiments, the host cell is a mammalian host cell
e.g., an HEK, CHO, or BHK cell. In a specific embodiment, the host
cell is an HEK 293 cell. In some embodiments, the host cell is an
invertebrate cell, e.g., an insect cell. In a specific embodiment,
the host cell is an SF9 cell.
[0375] Treatment
[0376] In some embodiments, the nucleic acid compositions (e.g.,
codon-altered polynucleotides) described herein are administered to
a subject in need thereof, in accordance with known administrative
methods. Methods for administering gene therapy vectors are well
known in the art. These include, without limitation, intravenous
administration, intramuscular injection, interstitial injection,
and intra-hepatic administration (e.g., intra-hepatic artery or
vein). For example, see Chuah MK et al., Hum Gene Ther.,
23(6):557-65 (2012); Chuah MK et al., J Thromb Haemost.,
10(8):1566-69 (2012); Chuah MK et al., J Thromb Haemost. 11 Suppl

17(5):387-92 (2010), each of which is hereby incorporated by
reference herein, for review.
[0377] Assessing Therapeutic Efficacy
[0378] The therapeutic efficacy of a hemophilia B treatment can be
evaluated, for example, by measuring the Factor IX-dependent
coagulation potential of blood from a subject being treated.
Metrics for assessing coagulation potential include, without
limitation, in vitro activated partial thromboplastin time assay
(APPT), Factor IX chromogenic activity assays, blood clotting
times, and Factor IX antigen levels (e.g., using a Factor
IX-specific ELISA). It should be noted that a therapeutic dose need
not result in wild-type levels of FIX in a patient; rather,
sufficient expression to decrease symptoms in a meaningful or
measurable way is considered therapeutic for the purposes of the
invention.
[0379] According to the National Hemophilia Foundation, a subject
is classified as having mild hemophilia B when their blood plasma
contains between 6% and 49% of the Factor IX activity of normal
human blood plasma. Subjects with mild hemophilia B typically
experience bleeding only after serious injury, trauma or surgery.
In many cases, mild hemophilia is not diagnosed until an injury,
surgery or tooth extraction results in prolonged bleeding. The
first episode may not occur until adulthood. Women with mild
hemophilia often experience menorrhagia, heavy menstrual periods,
and can hemorrhage after childbirth.
[0380] According to the National Hemophilia Foundation, a subject
is classified as having moderate hemophilia B when their blood
plasma contains between 1% and 5% of the Factor IX activity of
normal human blood plasma. Subjects with moderate hemophilia B tend
to have bleeding episodes after injuries. Bleeds that occur without
obvious cause are called spontaneous bleeding episodes.
[0381] According to the National Hemophilia Foundation, a subject
is classified as having severe hemophilia B when their blood plasma
contains less than 1% of the Factor IX activity of normal human
blood plasma. Subjects with severe hemophilia B experience bleeding
following an injury and may have frequent spontaneous bleeding
episodes, often into their joints and muscles.
[0382] In some embodiments, normal human blood plasma is defined as
containing 1 IU of Factor IX activity per mL. Thus, in some
embodiments, blood plasma from a subject classified with mild
hemophilia B contains between 0.06 and 0.49 IU of Factor IX
activity per mL. In some embodiments, blood plasma from a subject
classified with moderate hemophilia B contains between 0.01 and
0.05 IU of Factor IX activity per mL. In some embodiments, blood
plasma from a subject classified with severe hemophilia B contains
between 0.01 and 0.05 IU of Factor IX activity per mL.
[0383] Accordingly, in some embodiments, hemophilia B therapy is
therapeutically effective when it raises the average level of
Factor IX activity in the subject's blood/plasma. In some
embodiments, a therapeutically affective treatment raises the
average level of Factor IX activity in the subject's blood/plasma
by at least 1%, 2%, 3%, 4%, 5%, 6%, 7%, 8%, 9%, 10%, 15%, 20%, 25%,
30%, 35%, 40%, 45%, 50%, or more. In a specific embodiment, a
therapeutically effective hemophilia therapy increases the average
Factor IX activity in the blood/plasma of a subject by at least 5%.
In another specific embodiment, a therapeutically effective
hemophilia therapy increases the average Factor IX activity in the
blood/plasma of a subject by at least 10%. In another specific
embodiment, a therapeutically effective hemophilia therapy
increases the average Factor IX activity in the blood/plasma of a
subject by at least 15%. In another specific embodiment, a
therapeutically effective hemophilia therapy increases the average
Factor IX activity in the blood/plasma of a subject by at least
20%. In another specific embodiment, a therapeutically effective
hemophilia therapy increases the average Factor IX activity in the
blood/plasma of a subject by at least 25%. In another specific
embodiment, a therapeutically effective hemophilia therapy
increases the average Factor IX activity in the blood/plasma of a
subject by at least 30%.
[0384] In some embodiments, a therapeutically effective treatment
raises the average level of Factor IX activity in the subjects
blood such that the subject is classified as having a less severe
form of hemophilia B. For example, in one embodiment, a subject
originally classified with severe hemophilia B is reclassified with
moderate hemophilia B or mild hemophilia B after undergoing a
therapeutically effective treatment. In another embodiment, a
subject originally classified with moderate hemophilia B is
reclassified with mild hemophilia B after undergoing a
therapeutically effective treatment.
VI. Examples
Example 1
Codon-Altered Factor IX Expression Sequences Enhance FIX Expression
Levels
[0385] In order to generate gene therapy constructs providing
improved expression of heterologous Factor IX in vivo, a panel of
self-complementary AAV8-based vectors encoding a full-length Factor
IX preproprotein with an R384L amino acid substitution (FIXp-FL-AA
SEQ ID NO: 4)) were constructed. The Factor IX coding sequence of
each construct was altered to improve expression in humans through
several steps. Each Factor IX coding sequence was modified
according to an algorithm designed to account for
preferred/disfavored sequence motifs and to skew codon-usage
towards preferred human codons. Several algorithms were used for
this first step, as reported in Table 2. Intermediate codon-altered
sequences, resulting from application of the algorithms reported in
Table 2, where then further modified manually to reduce or
eliminate CpG dinucleotides, adjust the final GC content, adjust to
allow for preferred codon pairs, adjust to avoid disfavored codon
pairs, and adjust the final codon usage. For further information on
these considerations, see, e.g., Fath S. et al., PLoS. One., 6,
e17596 (2011); Haas J. et al., Curr. Biol., 6, 315-324 (1996); Tats
A., BMC Genomics. 9:463 (2008), Grote A. et al., Nucleic Acids
Research, 33(Web Server issue), W526-W531 (2005), Mirsafian H. et
al., Scientific World Journal., 639682 (2014), and Pechmann S. et
al., Nat Struct Mol Biol. 20(2):237-43 (2013), the contents of
which are expressly incorporated hereinby reference, in their
entireties, for all purposes, specifically for their teachings of
codon alteration considerations.
[0386] Each generated codon-altered coding sequence (e.g., CS02,
CS03, CS04, CS05, and CS06, shown in FIGS. 5 through 9,
respectively) encoded for an identical FIX(R384L) protein
(FIXp-FL-AA (SEQ ID NO: 4)). The CS02, CS03, and CS04 constructs
contain no CpG motifs, while CS05 and CS06 contain 11 and 3 CpGs,
respectively.
[0387] To use as controls, vector constructs incorporating
wild-type FIX coding sequences, with and without R384L Padua amino
acid substitutions, were also generated. The WH01 construct encodes
a wild type FIX preproprotein without the R384L Padua mutation, and
includes 20 CpG dinucleotides. The WH02 construct encodes a wild
type FIX preproprotein with the R384L Padua mutation, and includes
19 CpG dinucleotides.
[0388] The WH01 and WH02 constructs include 20 and 19 CpGs in their
coding sequences, respectively. In contrast, the CS02, CS03, and
CS04 constructs contain no CpG motifs, while the CS05 and CS06
constructs contain 11 and 3 CpGs, respectively.
[0389] As shown in FIG. 1A, the codon-altered Factor IX coding
sequences were inserted into an Adeno-associated virus ("AAV")
transgene cassette containing a mouse transthyrethrin
enhancer/promoter (SEQ ID NO: 52), a mouse minute virus ("MVM")
intron (SEQ ID NO: 53), the codon-altered FIX construct including
the R384L "Padua" amino acid substitution (U.S. Pat. No. 6,531,298;
Simione et al., NEJM 361:1671-75 (2009); the R384L mutation is
commonly reported as an R338L mutation, referring to the position
of the wild-type arginine in the human single-chain FIX protein
lacking the signal and propeptide), followed by a bovine growth
hormone polyA element (SEQ ID NO: 54). The gene cassette is flanked
by AAV2 inverted terminal repeats ("ITR") (SEQ ID NOs:51 and 55).
The left ITR repeat includes a mutation in the terminal concatemer
resolution site resulting in the self-complementary (sc) phenotype
of the vectors. The basic vector design is described in detail in
Wu et al., Mol. Ther. 16:280-89 (2008) and in PCT Publication
Number WO 2014/064277 Al, the contents of which are incorporated
herein by reference, in their entireties, for all purposes.
[0390] The CS and WH Factor IX AAV constructs were administered to
B6/129P2-F9tmlDws FIX knockout mice (described in Lin et al.,
Blood, 90:3962-66 (1997), the content of which is incorporated by
reference herein, in its entirety, for all purposes). AAV vector
dilutions were injected into animals (4-8 animals per group) via
the lateral tail vein based upon the individual animals body
weights (4.times.10E11 vector genomes/ kilogram (vg/kg) body
weight). Blood samples were collected at defined time intervals by
retro-orbital puncture after dosing according to known procedures
using glass capillaries. Blood was then transferred to a tube
pre-filled with sodium citrate anticoagulant and plasma was
obtained by standard procedures and frozen at -20.degree. C.
[0391] Expression of the various Factor IX constructs was
determined and plasma FIX levels at day 14 in FIX knockout mice
were used to judge the potency of the constructs after tail vein
injection of the vectors into the mice, as reported in Table 2. By
day 14, expression levels in the knockout mouse model have nearly
reached the maximum FIX expression. As shown in Table 2, the WH02
FIX(R384L) control construct was expressed at 1.03 units FIX at day
14 after administration of 4.times.10E11 vector genomes/ kilogram
(vg/kg) body weight. This expression level was used as a baseline
to determine fold-enrichment of the codon-altered Factor IX
constructs. As reported in Table 2, the CS codon-altered constructs
provided between about 2-fold and 4-fold increased expression, as
compared to the WH02 control construct, encoded by a wild-type
polynucleotide sequence. Most notably, the CS06 codon-altered
construct provided 4.2-fold greater Factor IX activity than the
WH02 control construct and 21.6-fold greater Factor IX activity
than the WH01 (wild-type Factor IX) control construct.

Example 2
Liver-Specific CRM8 Elements Enhance Expression of FIX in Mice
[0392] To further increase Factor IX expression and activity from
the codon-altered constructs, one to three copies of a
liver-specific cis-regulatory control element (CRM8 (SEQ ID NO:
39)), as reported in Nair et al., Blood 123:3195-99 (2014) was
incorporated into the gene cassette, creating the construct
diagramed in FIG. 1B. AAV vectors harboring the CS02 codon-altered
FIX coding sequence with zero (CS02-CRM8.0-V), one (CS02-CRM8.1-V),
two (CS02-CRM8.2-V), or three (CS02-CRM8.3-V) CRM8 control elements
were injected into wild-type mice by the tail vein route. Human FIX
antigen in mouse plasma was then measured over time with a human
FIX-specific ELISA assay.
[0393] As reported in Table 3, use of CRM8 regulatory elements
increased Factor IX expression in vivo by about 2-fold and 4-fold,
as compared to expression from the control construct lacking a CRM8
element, 21-days post infection. For example, the CS02-CRM8.1-V
vector, containing a single CRM8 element, provided twice the
expression of FIX as did the CS02-CRM8.0-V control vector. The
inclusion of multiple copies of the CRM8 element further improved
this expression. For example, vectors containing 2 copies of the
CRM8 element provided three-fold expression and vectors containing
3 copies of the CRM8 element provided 3.4-fold expression, relative

Liver-Specific CRM8 Elements Enhance Expression of FIX in Human
Hepatic Cells
[0394] The CS02 Factor IX gene therapy constructs containing 0-3
copies of the CRM8 liver-specific regulatory control element, as
described in Example 2, were further tested by in vitro biopotency
assays performed with the human hepatic cell line HepG2. Briefly,
HepG2 cells were infected with one of the CS02-CRM8-V AAV vectors,
as described in Example 2, and FIX activity was measured by a
chromogenic substrate assay three days after infection. Consistent
with the results reported in Example, 2, all vectors containing a
CRM8 regulatory control element provided higher FIX expression, as
reported in Table 4. Striking, the effect of using multiple CRM8
elements was even more pronounced in the human HepG2 cells than in
the mouse model. For example, vectors containing 2 copies of the
CRM8 element provided 6.7-fold expression and vectors containing 3
copies of the CRM8 element provided 12.8-fold expression, relative
to the control vector. This confirms the positive effects that the
CRM8 regulatory control element has on FIX expression in these
vectors.

Single Stranded FIX AAV8 Vectors Provide Similar In Vivo Expression
as Comparable Self-Complementary Vectors
[0395] In some instances, self-complementary (sc) AAV vectors
express a transgene cassette more efficiently than a similar
single-stranded (ss) AAV vector. This is presumably due to more
rapid double strand formation after uncoating of a
self-complementary vector genome in the cell nucleus. For review,
see, McCarty D., Mol. Ther., (16):1648-56 (2008), the content of
which is incorporated herein by reference, in its entirety, for all
purposes.
[0396] A recent study confirmed this effect using an EGFP vector.
Bell et al., Hum. Gene Ther. Methods, (27):228-37 (2016). However,
the study also showed that this effect was transgene and dose
dependent. For example, a human ornithine transcarbamylase (hOTC)
gene cassette in a self-complementary AAV8 vector showed better
expression at low dose in the liver of mice as compared to a
corresponding single-stranded vector. However, this effect could
not be demonstrated at a high dose suggesting that the effect, at
least in the non-secreted gene studied, was transgene and dose
dependent. Id.
[0397] In order to explore the properties of the disclosed
codon-altered FIX gene constructs in the context of single-stranded
and self-complementary design, single-stranded constructs harboring
a C SO6 codon-altered FIX(R338L) gene and two intact ITRs were
constructed with and without CRM8 regulatory control elements, as
diagramed in FIGS. 1D and 1C, respectively. The single-stranded
(ss) vectors were produced in an HEK293 cell system, and Factor IX
expression was compared to expression of the self-complementary
constructs reported in Examples 1-3.
[0398] First, the self-complementary (sc) and single-stranded (ss)
CS06-CRM8.0-V constructs were tested in vivo following injection
into B6/129P2-F9tm1Dws FIX knockout mice, as described above.
Surprisingly, as reported in Table 5, the self-complementary (sc)
and single-stranded (ss) CS06 vector constructs showed very similar
plasma levels of FIX activity, suggesting the reported advantage of
sc vectors, as compared to ss vectors, does not hold for the
codon-altered Factor IX constructs described herein. Expression is
dependent on many parameters including the transgene construct, the
stability of transcript, the promoter(s) used in the construct,
time, and dose. As shown in Table 5, under the conditions chosen to
correct bleeding and obtain long-term expression in FIX ko mice,
the corresponding sc and ss vectors provided substantially similar
expression levels.
[0399] The effects of the liver-specific CRM8 regulatory control
element on FIX expression was also investigated in the
single-stranded vector background. As reported in Table 5,
inclusion of one CRM8 element in the single-stranded vector
improved FIX expression in the B6/129P2-F9tmlDws FIX knockout mice.
Inclusion of three CRM8 elements further improved FIX expression
from the single-stranded CS06 construct, to levels slightly more
than 2-fold above the self-complementary CS06 control, lacking a
CRM8 element. As compared to the wild-type WH02 construct, the
single-stranded CS06 vectors provided up to 7-fold greater
expression, when paired with three CRM8 regulatory control
elements.

Example 5
Single Stranded FIX AAV8 Vectors Provide Better FIX Expression in
Human Hepatic Cells than Comparable Self-Complementary Vectors
[0400] Factor IX expression from the single-stranded CS06 vectors
described in Example 4 was then investigated in human HepG2 cells
and compared to similar self-complementary vector constructs.
Consistent with the in vivo results reported in Example 4,
single-stranded CS06 vectors without a CRM8 element provided FIX
expression at slightly lower levels than a comparative
self-complementary vector in HepG2 cells. However, inclusion of a
single CRM8 element increased FIX expression from the
single-stranded CS06 vector to a level 2.6-times greater than
expression from the self-complementary CS06 vector, as reported in
Table 6.
[0401] Most surprisingly, however, inclusion of three CRM8 elements
in the single-stranded CS06 vector increased FIX expression to a
level 16.8-times greater than expression from the
self-complementary CS06 vector. The increased FIX expression was
more than 100-times greater than FIX expression from the WH02
control vector. In summary, the single-stranded CS06 vector
containing three CRM8 elements provides the highest expression
levels in both the in-vivo and the in-vitro biopotency assays.

Materials and Methods for Examples 1-5
[0402] Animal experiments. For the experiments in FIX knockout
model, the FIX ko mouse strain B6/129P2-F9tmlDws (developed by Lin
et al., 1997. Blood 90 :3962-6) were used. In the wild-type mouse
model 4-5 week old male C57BL6-J B16 mice were used. Both strains
were obtained from commercial breeders. The AAV vector dilutions
were injected into animals (4-8 animals per group) via the lateral
tail vein based upon the individual animals body weights. Blood
sampling was done at defined time intervals by retro-orbital
puncture after dosing according to known procedures using glass
capillaries. Blood was then transferred to a tube pre-filled with
sodium citrate anticoagulant and plasma was obtained by standard
procedures and frozen at -20.degree. C.
[0403] In vitro biopotency assay in HepG2 cells including FIX
chromogenic substrate assay. The in vitro biopotency assay for gene
therapy vector preparations was performed in the human hepatic cell
line HepG2 (ATCC HB-8065). After treatment with hydroxyurea, cells
were infected with AAV8FIX vectors and incubated for approximately
96 hrs. During incubation time, FIX was expressed and released into
the cell supernatant and FIX-activity was determined by chromogenic
endpoint measurement (Rossix AB, Sweden). Each assay run includes a
standard curve of purified AAV-FIX vector material using MOI
ranging between 700 and 7000. FIX activity of the standard at MOI
3270 is set as Bio Potency Unit (BPU) of 1.
[0404] Human FIX quantifications in mouse plasma. To quantify human
FIX in knock-out mouse plasma FIX coagulation assays were performed
using standard FIX coagulation analytics. To quantify human FIX
antigen in plasma of the wild-type mice a commercially available
ELISA kit (ASSERACHROM IX:AG (cat. nr. 00943 Stago BNL) was used
that specifically detects human FIX.
Example 6
Improved Transcriptional Efficacy by Incorporation of CRM8
Elements
[0405] To address whether improved biopotency of CRM8-containing
vectors results from increased transcriptional efficacy, a human
liver cell line (HepG2) and mouse liver cells (FIX knock-out mice)
were transduced with single-stranded CS06 vectors containing 0, 1,
or 3 CRM8 elements. FIX mRNA and DNA levels were determined and
presented as ratio between normalized FIX mRNA and DNA levels.
[0406] In the in vitro model, inclusion of one CRM8 element
(CS06-CRM8.1-ssV) or three CRM8 elements (CS06-CRM8.3-ssV (SEQ ID
NO: 40)) resulted in 5-fold and 23-fold higher human FIX mRNA
levels in transduced human hepatic cells than in cells transduced
with vector lacking a CRM8 element (CS06-CRM8.0-ssV) (Table 6),
respectively. Similarly, in the in vivo model, FIX expression in
murine liver from vectors containing one or three CRM8 elements was
2.0-fold and 2.8-fold higher than FIX expression from vector
lacking a CRM8 element (Table 6), respctively. Both models support
that CRM8 element(s) provide a beneficial effect in improving
transcriptional activity of a FIX construct.

Methods for Example 6
[0407] Quantitative real-time polymerase chain reaction including
RNA and DNA extraction. Genomic DNA and total RNA were extracted
from frozen livers (see animal experiments) or HepG2 cells (see in
vitro biopotency assay in HepG2 cells) by standard procedures. For
analytics of the in vivo experiments, a subset of three animals per
treatment group close to the mean FIX activity of the respective
group at day 14 (inside the mean.+-.SD) was selected. cDNA was
synthesized using an oligo (dT20) primer, the SuperScript III
reverse transcriptase (RT) and DNase-treated total RNA according to
the manual (DNeasy Blood & Tissue Kit, Qiagen, Germany; RNeasy
mini kit, Qiagen).
[0408] FIX-transgene copy numbers in both gDNA and cDNA samples
were determined by a fluorescent-based quantitative real-time
polymerase chain reaction (qPCR), amplifying a 96 bp sequence of
FIX exon 6. Murine (3-actin served as endogenous control and was
quantified using a commercially available TaqMan assay. qPCR data
analysis was performed using the specific device's software,
calculating the FIX or (3-actin copies per reaction based on the
linear regression parameters of the standard curve. Further, the
results were normalized to 1.mu.g of either RNA or DNA and the
mRNA:DNA ratio was calculated.
