STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH
[0002] Not applicable.
STATEMENT REGARDING MICROFICHE APPENDIX
[0003] Not applicable.
FIELD OF THE INVENTION
[0004] The present invention relates to the use of ligands
comprising antigen binding domains specific for certain antigens,
like chimeric antigen receptors (CAR) and/or engineered cells
provided with such ligands for treatment of human cancer.
BACKGROUND
[0005] Cancer is a broad group of diseases involving unregulated
cell growth. In cancer, cells divide and grow uncontrollably,
forming malignant tumors, and invading nearby parts of the body.
The cancer may also spread to more distant parts of the body
through the lymphatic system or bloodstream. There are over 200
different known cancers that affect humans. Whereas good treatment
options are available for many cancer types, others still represent
unmet medical needs.
[0006] The technology of chimeric antigen receptor (CAR) may
provide a promising approach for adoptive cell immunotherapy for
cancer. Commonly, CARs comprise a single chain fragment variable
(scFv) of an antibody specific for a tumor associated antigen (TAA)
coupled via hinge and transmembrane regions to cytoplasmic domains
of T-cell signaling molecules. For example, well known lymphocyte
activation moieties include a T-cell costimulatory (e.g. CD28,
CD137, OX40, ICOS, and CD27) domain in tandem with a T-cell
triggering (e.g. CD3.zeta.) moiety. The CAR-mediated adoptive
immunotherapy allows CAR-grafted cells to directly recognize the
TAAs on target tumor cells in a non-HLA-restricted manner.
[0007] Paramount for immunotherapy for cancer based on CAR is the
selection of antigens specific for the respective tumor cells.
Object of the invention was to provide such antigens specific for
cancer cells, especially for pancreas cancer cells in order to
engineer killer cells which then kill/lyse cancer cells without
attacking non-tumor cells.
SUMMARY
[0008] It has been found that a distinct group of cell surface
antigens is expressed on several human cancer cells, especially on
human pancreas cancer cells, but not or to a lower level on
non-malignant cells. Accordingly, these antigens (also referred to
as "markers") can be used to identify and/or mark and/or destroy
and/or disable escape mechanisms of such cancer cells via ligands
that specifically bind to the markers.
[0009] Therefore, the invention relates to a ligand, comprising an
antigen binding domain specific for one or more antigens
characterized in that the ligand is a chimeric antigen receptor
(CAR), comprising an antigen binding domain specific for one or
more antigens selected from the group consisting of CLA, CD142,
CD73, CD49c, CD66c, CD104, CD318 and TSPAN8.
[0010] Another object of the invention are methods of binding a
cancer cell with a ligand comprising an antigen binding domain
specific for one or more antigens selected from the group
consisting of CLA, CD142, CD73, CD49c, CD66c, CD104, CD318 and
TSPAN8.
[0011] The ligands as further disclosed may be an antibody or a CAR
or an engineered cell expressing at least one such ligands.
[0012] Another objects of the invention are populations of
engineered cells expressing at least one of said ligands,
pharmaceutical compositions comprising the population of engineered
cells and/or the use of the population of engineered cells or the
pharmaceutical composition for treatment of human cancer.

DETAILED DESCRIPTION OF THE INVENTION
[0021] In a first embodiment of the invention, the ligand comprises
at least two different antigen binding domains specific for at
least two different antigens selected from the group consisting of
CLA, CD142, CD73, CD49c, CD66c, CD104, CD318 and TSPAN8. For
example, the ligand may comprise antigen binding domains specific
for CLA and CD66c or specific for CLA and TSPAN8.
[0022] In a preferred method of binding a cancer cell, the cancer
cell (or population of cancer cells) is bound with a ligand
comprised at least two different antigen binding domains specific
for at least two different antigens selected from the group
consisting of CLA, CD142, CD73, CD49c, CD66c, CD104, CD318 and
TSPAN8. Again, the ligand may comprise antigen binding domains
specific for CLA and CD66c or specific for CLA and TSPAN8.
Definitions
[0023] The term "tumor" is known medically as a neoplasm. Not all
tumors are cancerous; benign tumors do not invade neighboring
tissues and do not spread throughout the body.
[0024] The term "cancer" is known medically as a malignant
neoplasm. Cancer is a broad group of diseases involving unregulated
cell growth. In cancer, cells (cancerous cells) divide and grow
uncontrollably, forming malignant tumors, and invading nearby parts
of the body. The cancer may also spread to more distant parts of
the body through the lymphatic system or bloodstream.
[0025] The term "isolated" means altered or removed from the
natural state. For example an isolated population of cells means an
enrichment of such cells and separation from other cells which are
normally associated in their naturally occurring state with said
isolated cells. An isolated population of cells means a population
of substantially purified cells which is a homogenous population of
cells.
[0026] The terms "specifically binds" or "specific for" with
respect to an antigen-binding domain of a ligand like an antibody,
of a fragment thereof or of a CAR refer to an antigen-binding
domain which recognizes and binds to a specific antigen, but does
not substantially recognize or bind other molecules in a sample. An
antigen-binding domain that binds specifically to an antigen from
one species may bind also to that antigen from another species.
This cross-species reactivity is not contrary to the definition of
that antigen-binding domain as specific. An antigen-binding domain
that specifically binds to an antigen may bind also to different
allelic forms of the antigen (allelic variants, splice variants,
isoforms etc.). This cross reactivity is not contrary to the
definition of that antigen-binding domain as specific.
[0027] The terms "engineered cell" and "genetically modified cell"
as used herein can be used interchangeably. The terms mean
containing and/or expressing a foreign gene or nucleic acid
sequence which in turn modifies the genotype or phenotype of the
cell or its progeny. Especially, the terms refers to cells,
preferentially T cells which are manipulated by recombinant methods
well known in the art to express stably or transiently peptides or
proteins which are not expressed in these cells in the natural
state. For example, T cells are engineered to express an artificial
construct such as a chimeric antigen receptor on their cell
surface. For example, the sequences encoding the CAR may be
delivered into cells using a retroviral or lentiviral vector.
[0028] The amino acid sequences given in SEQ ID NO:1-32,
respectively (in the one-letter code of amino acids) shall refer to
all constellations of the respective amino acid sequence which
retains the intended function of the respective amino acid sequence
as defined. Therefore, all variants of the amino acid sequences
defined in the sequence listings having a sequence identity of at
least 70%, or at least 75%, 80%, 85%, 90%, 95%, 97%, 98% or 99% at
the amino acid sequence level are included in the scope of the
present invention. In the context of the present invention,
"sequence identity" may be determined using pairwise alignments
using alignments programs for amino acid sequences well known to
the art.
[0029] T cells or T lymphocytes are a type of lymphocyte that play
a central role in cell-mediated immunity. They can be distinguished
from other lymphocytes, such as B cells and natural killer cells
(NK cells), by the presence of a T-cell receptor (TCR) on the cell
surface. There are several subsets of T cells, each with a distinct
function.
[0030] T helper cells (Tx cells) assist other white blood cells in
immunologic processes, including maturation of B cells into plasma
cells and memory B cells, and activation of cytotoxic T cells and
macrophages. These cells are also known as CD4.sup.+ T cells
because they express the CD4 glycoprotein on their surface. Helper
T cells become activated when they are presented with peptide
antigens by MHC class II molecules, which are expressed on the
surface of antigen-presenting cells (APCs). Once activated, they
divide rapidly and secrete small proteins called cytokines that
regulate or assist in the active immune response. These cells can
differentiate into one of several subtypes, including T.sub.H1,
T.sub.H2, T.sub.H3, T.sub.H17, Th9, or T.sub.FH, which secrete
different cytokines to trigger a different type of immune response.
Signaling from the APC directs T cells into particular
subtypes.
[0031] Cytotoxic T cells (T.sub.C cells, or CTLs) destroy infected
cells and tumor cells, and are also implicated in transplant
rejection. These cells are also known as CD8.sup.+ T cells since
they express the CD8 glycoprotein at their surface. These cells
recognize their targets by binding to antigen associated with MHC
class I molecules, which are present on the surface of all
nucleated cells.
[0032] Memory T cells are a subset of antigen-specific T cells that
persist long-term after an infection has resolved. They quickly
expand to large numbers of effector T cells upon re-exposure to
their cognate antigen, thus providing the immune system with
"memory" against past infections. Memory T cells comprise three
subtypes: central memory T cells (T.sub.CM cells) and two types of
effector memory T cells (T.sub.EM cells and T.sub.EMRA cells).
Memory cells may be either CD4.sup.+ or CD8.sup.+. Memory T cells
typically express the cell surface molecule CD45RO.
[0033] Regulatory T cells (T.sub.reg cells), formerly known as
suppressor T cells, are crucial for the maintenance of
immunological tolerance. Their major role is to shut down T
cell-mediated immunity toward the end of an immune reaction and to
suppress auto-reactive T cells that escaped the process of negative
selection in the thymus. Two major classes of CD4.sup.+ T.sub.reg
cells have been described--Foxp3+T.sub.reg cells and
Foxp3-T.sub.reg cells.
[0034] Natural killer T cells (NKT cells) bridge the adaptive
immune system with the innate immune system. Unlike conventional T
cells that recognize peptide antigens presented by major
histocompatibility complex (MHC) molecules, NKT cells recognize
glycolipid antigen presented by a molecule called CD1d. Once
activated, these cells can perform functions ascribed to both
T.sub.h and T.sub.c cells (i.e., cytokine production and release of
cytolytic/cell killing molecules).
[0035] Immunotherapy is a medical term defined as the "treatment of
disease by inducing, enhancing, or suppressing an immune response"
Immunotherapies designed to elicit or amplify an immune response
are classified as activation immunotherapies, while immunotherapies
that reduce or suppress are classified as suppression
immunotherapies. Cancer immunotherapy as an activating
immunotherapy attempts to stimulate the immune system to reject and
destroy tumors. Adoptive cell transfer uses cell-based, such as T
cell-based cytotoxic responses to attack cancer cells. T cells that
have a natural or genetically engineered reactivity to a patient's
cancer are generated in vitro and then transferred back into the
cancer patient.
[0036] The term "biomarker" or "marker" is widespread in the art
and may broadly denote a biological molecule and/or a detectable
portion thereof (e.g. a nucleic acid, a peptide or a lipid such as
a glycolipid) whose qualitative and/or quantitative evaluation in
an individual is predictive or informative (e.g., predictive,
diagnostic and/or prognostic) with respect to one or more aspects
of the individual's phenotype and/or genotype. E.g. the biomarker
is predictive or informative with respect to the outcome for
chemotherapeutic treatment of a cancer in an individual. A
biomarker is expressed ("expression of the biomarker") if the
biomarker is detectable with methods known in the art. Therefore
expression of biomarkers encompasses not only expression at nucleic
acid level (DNA and/or RNA) and protein level but also expression
(presence) of other biological structures on or in the cells such
as glycolipids or the activity of a protein.
[0037] The term "target" as used herein refers to an antigen or
epitope associated with a cell that should be recognized
specifically by an antigen binding domain, e.g. an antigen binding
domain of an antibody or of a CAR. The antigen or epitope for
antibody recognition can be bound to the cell surface but also be
secreted, part of the extracellular membrane, or shed from the
cell.
[0038] The term "antibody" as used herein refers to polyclonal or
monoclonal antibodies and fragments thereof, which can be generated
by methods well known to the person skilled in the art. The
antibody may be of any species, e.g. mice, rat, sheep, human. For
therapeutic purposes, if non-human antigen binding fragments are to
be used, these can be humanized by any method known in the art. The
antibodies may also be modified antibodies (e.g. oligomers,
reduced, oxidized and labeled antibodies).
[0039] The term "killer cell" as used herein refers to a cell that
can kill/lyse another cell, e.g. a cancer cell. Most frequently, T
cells, NK cells, dendritic cells and macrophages can be used as
killer cells.
[0040] The term "engineered killer cell" as used herein refers to a
killer cell that is genetically modified to allow for the specific
killing of a target cell, e.g. a cell modified with a CAR against a
target to kill tumor cell expressing the respective target.
Chimeric Antigen Receptor (CAR)
[0041] The chimeric antigen receptor (CAR) according to the
invention may comprise an antigen binding domain conjugated to a
transmembrane domain and/or a intracellular signaling domain, as
shown by way of example in FIG. 1.
[0042] In a first embodiment of the invention, the ligand is a
chimeric antigen receptor (CAR), comprising an antigen binding
domain specific for one or more antigens selected from the group
consisting of CLA, CD142, CD73, CD49c, CD66c, CD104, CD318 and
TSPAN8.
[0043] In a second embodiment of the invention, the ligand is a
CAR, comprising an antigen binding domain specific for CLA in
combination with one or more antigens selected from the group
consisting of CD142, CD73, CD49c, CD66c, CD104, CD318 and
TSPAN8.
[0044] In a third embodiment of the invention, the ligand is a CAR,
comprising an antigen binding domain, an transmembrane domain
and/or an intracellular signaling domain and comprising at least
two antigen binding domains specific for two different antigens
selected from the group consisting of CLA, CD142, CD73, CD49c,
CD66c, CD104, CD318 and TSPAN8 are conjugated to the same or a
different transmembrane domain and/or intracellular signaling
domain.
[0045] In another embodiment of the invention, the antigen binding
domain of a CAR binds a hapten that is coupled to a polypeptide
("haptenylated" polypeptide), wherein the polypeptide may bind to a
tumor associated antigen. Such CARs are for example disclosed in
U.S. Pat. No. 9,233,125B2 and are known in the art as "anti-tag"
CAR. Similar, the extracellular part of the CAR of the invention
may comprise a linker/label epitope (LLE) binding domain as antigen
binding domain that binds to a linker/label epitope (LLE) that is
part of a target cell binding molecule Such "anti-LLE CARs" are
disclosed in the European patent application no. EP16196487.9. Both
types of CARs are universal and/or adaptable CAR. Both the
hapten(s) and the LLE are "tags" that are coupled directly or
indirectly to a polypeptide (the tagged polypeptide), wherein the
polypeptide may bind to a tumor associated antigen expressed on the
(cell) surface of a target cell.
[0046] In this embodiment, the ligand comprises an antigen binding
domain specific for one or more antigens characterized in that the
ligand is a chimeric antigen receptor (CAR), comprising an anti tag
binding region which can bind to a tag which is coupled to an
antigen binding domain specific for one or more antigens selected
from the group consisting of CLA, CD142, CD73, CD49c, CD66c, CD104,
CD318 and TSPAN8. Suitable tags are for example, but not limited
to, Biotin, other haptens, FITC or other fluorochrome molecules,
FLAG, HIS, YOL MYC, Dextran, FcR, antibody-isotypes, artificially
engineered epitopes, FAB or FAB2 binders.
[0047] The transmembrane domain of the CAR may comprise a sequence
of the transmembrane domains of 4-1BB, CD8 and/or CD28; and the
intracellular signaling domain comprises a sequence of the
intracellular signaling domains of one or more of CD28, CD137 and
CD3zeta.
[0048] In a preferred variant of this embodiment, the chimeric
antigen receptor (CAR) comprises an antigen binding domain specific
for CLA without an additional antigen binding domain or additional
CAR, wherein the antigen binding domain is conjugated to one
transmembrane domains and one or more signaling domains. This
variant is shown by way of example in FIG. 2 A.
[0049] In a second variant of the invention, the chimeric antigen
receptor (CAR) comprises at least two antigen binding domains
specific for two or more antigens selected from the group
consisting of CLA (cutaneous lymphocyte antigen), CD142, CD73,
CD49c, CD66c, CD104, CD318 and TSPAN8, wherein the antigen binding
domains are conjugated to different transmembrane domains and/or
signaling domains. This variant is shown by way of example in FIG.
2 b.
[0050] In a third variant of the invention, the chimeric antigen
receptor (CAR) comprises at least two antigen binding domains
specific for two or more antigens selected from the group
consisting of CLA (cutaneous lymphocyte antigen), CD142, CD73,
CD49c, CD66c, CD104, CD318 and TSPAN8, wherein the antigen binding
domains are conjugated to the same (one) transmembrane domain and
signaling domains. This variant is shown by way of example in FIG.
2 c.
[0051] In a forth variant of the invention, the chimeric antigen
receptor (CAR) comprises at least two antigen binding domains
specific for two or more antigens selected from the group
consisting of CLA (cutaneous lymphocyte antigen), CD142, CD73,
CD49c, CD66c, CD104, CD318 and TSPAN8, wherein the antigen binding
domains are conjugated to different transmembrane domains and
signaling domains and the antigen binding domains origin from one
vector. This variant is shown by way of example in FIG. 2 d.
[0052] CLA is the cutaneous lymphocyte-associated antigen (CLA), a
specialized glycoform of P-selectin glycoprotein ligand-1 (PSGL-1).
It serves as a ligand for selectins, including CD62E (ELAM-1) and
CD62L (LECAM-1). CLA is a unique skin-homing receptor and is
predominantly found on a minor subset of human T cells that
infiltrate the skin. This post-translational modification of PSGL-1
is thought to serve as a mechanism to regulate tissue-specific
homing of CD4+ and CD8+ memory/effector T cells from peripheral
blood to the skin, which plays an essential role during many
inflammatory and certain malignant skin diseases.
[0053] In peripheral blood, CLA is not only found on skin-homing
memory/effector T cells, but is also found to be expressed on
memory/effector B cells, NK cells, blood dendritic cells, and on
monocytes. CLA is furthermore found on Langerhans cells in the
skin.
[0054] In order to enhance the specific recognition of cancer
cells, the chimeric antigen receptor (CAR) may comprise an antigen
binding domain specific for CLA in combination with one or more
(like two, three or four) antigens selected from the group
consisting of CD142, CD73, CD49c, CD66c, CD104, CD318 and TSPAN8.
Preferred combinations specific for pancreas cancer are CLA with
TSPAN8 and CLA with CD66c.
[0055] The antigen binding domain of said CAR may comprise, for
example, full length heavy chain, Fab fragments, single chain Fv
(scFv) fragments, divalent single chain antibodies or diabodies,
each of which are specific for one or more of the target antigens
CLA, CD142, CD73, CD49c, CD66c, CD104, CD318 and TSPAN8.
[0056] The antigen binding domain of said CAR may comprise the
amino acid sequences of SEQ ID NO:1 and SEQ ID NO:2. The relevant
sites causing specificity for antigen binding are the CDRs
according to the IMGT (the international ImMunoGeneTics information
system for immunoglobulins or antibodies) definition which are
underlined in the sequence. The antigen binding domain of said CAR
may comprise a scFv comprising the amino acid sequence of SEQ ID
NO:17 or SEQ ID NO:18.
[0057] The present invention also encompasses nucleic acids (DNA or
RNA) constructs comprising sequences encoding for amino acids
sequences of a CAR specific for the disclosed markers.
[0058] In one embodiment of the invention a DNA construct (vector,
plasmid) is generated encoding for a CAR specific for the disclosed
markers. A nucleic acid sequence encoding for an antigen binding
domain specific for the disclosed markers is fused at least to a
nucleic acid sequence encoding a transmembrane domain and
subsequent a nucleic acid sequence encoding a intracellular domain.
The construction of such expression vectors can be performed by
recombinant methods well known in the art. Alternatively, the
nucleic acid sequences can be produced synthetically.
[0059] Alternatively, the CAR may be composed of further parts such
as a linker and/or hinge and/or may be composed as di- or
multi-chain CAR as described below.
[0060] As shown in general in FIGS. 1 and 2, a CAR may comprise an
extracellular domain comprising the antigen binding domain, a
transmembrane domain and an intracellular signaling domain. The
extracellular domain may be linked to the transmembrane domain by a
linker. The extracellular domain may also be linked to a signal
peptide.
[0061] A "signal peptide" refers to a peptide sequence that directs
the transport and localization of the protein within a cell, e.g.
to a certain cell organelle (such as the endoplasmic reticulum)
and/or the cell surface.
[0062] An "antigen binding domain" refers to the region of the CAR
that specifically binds to an antigen (and thereby is able to
target a cell containing an antigen). The CARs of the invention may
comprise one or more antigen binding domains. Generally, the
antigen binding domain on the CAR are extracellular. The antigen
binding domain may comprise an antibody or a fragment thereof. The
antigen binding domain may comprise, for example, full length heavy
chain, Fab fragments, single chain Fv (scFv) fragments, divalent
single chain antibodies or diabodies. Any molecule that binds
specifically to a given antigen such as affibodies or ligand
binding domains from naturally occurring receptors can be used as
an antigen binding domain. Often the antigen binding domain is a
scFv. Normally, in a scFv the variable portions of an
immunoglobulin heavy chain and light chain are fused by a flexible
linker to form a scFv. Such a linker may be for example the
"(G.sub.4/S.sub.1).sub.3-linker".
[0063] In some instances, it is beneficial for the antigen binding
domain to be derived from the same species in which the CAR will be
used in. For example, if it is planned to use it therapeutically in
humans, it may be beneficial for the antigen binding domain of the
CAR to comprise a human or humanized antibody or fragment thereof.
Human or humanized antibodies or fragments thereof can be made by a
variety of methods well known in the art.
[0064] "Spacer" or "hinge" as used herein refers to the hydrophilic
region which is between the antigen binding domain and the
transmembrane domain. The CARs of the invention may comprise an
extracellular spacer domain but is it also possible to pass such a
spacer. The spacer may include Fc fragments of antibodies or
fragments thereof, hinge regions of antibodies or fragments
thereof, CH2 or CH3 regions of antibodies, accessory proteins,
artificial spacer sequences or combinations thereof. A prominent
example of a spacer is the CD8alpha hinge.
[0065] The transmembrane domain of the CAR can be derived from any
desired natural or synthetic source for such domain. If the source
is natural the domain may be derived from any membrane-bound or
transmembrane protein. The transmembrane domain may be derived for
example from CD8alpha or CD28.
[0066] The cytoplasmic domain or the intracellular signaling domain
of the CAR of the invention is responsible for activation of at
least one of the normal effector functions of the immune cell in
which the CAR is expressed. "Effector function" means a specialized
function of a cell, e.g. in a T cell an effector function may be
cytolytic activity or helper activity including the secretion of
cytokines. The intracellular signaling domain refers to the part of
a protein which transduces the effector function signal and directs
the cell expressing the CAR of the invention to perform a
specialized function. The intracellular signaling domain may
include any complete or truncated part of the intracellular
signaling domain of a given protein sufficient to transduce the
effector function signal.
[0067] Prominent examples of intracellular signaling domains for
use in the CARs include the cytoplasmic sequences of the T cell
receptor (TCR) and co-receptors that act in concert to initiate
signal transduction following antigen receptor engagement.
[0068] Generally, T cell activation can be mediated by two distinct
classes of cytoplasmic signaling sequence, firstly those that
initiate antigen-dependent primary activation through the TCR
(primary cytoplasmic signaling sequences) and secondly those that
act in an antigen-independent manner to provide a secondary or
co-stimulatory signal (secondary cytoplasmic signaling
sequences).
[0069] Primary cytoplasmic signaling sequences that act in a
stimulatory manner may contain ITAMs (immunoreceptor tyrosine-based
activation motifs signaling motifs).
[0070] Examples of ITAM containing primary cytoplasmic signaling
sequences often used in CARs derived from TCR zeta, FcR gamma, FcR
beta, CD3 gamma, CD3 delta, CD3 epsilon, CD5, CD22, CD79a, CD79b,
and CD66d.
[0071] The cytoplasmic domain of the CAR can be designed to
comprise the CD3-zeta signaling domain by itself or combined with
any other desired cytoplasmic domain(s). The cytoplasmic domain of
the CAR can comprise a CD3 zeta chain portion and a costimulatory
signaling region. The costimulatory signaling region refers to a
part of the CAR comprising the intracellular domain of a
costimulatory molecule. A costimulatory molecule is a cell surface
molecule other than an antigen receptor or their ligands that is
required for an efficient response of lymphocytes to an antigen.
Examples for costimulatory molecule are CD27, CD28, 4-1BB (CD137),
OX40, CD30, CD40, PD-1, ICOS, lymphocyte function-associated
antigen-1 (LFA-1), CD2, CD7, LIGHT, NKG2C, B7-H3.
[0072] The cytoplasmic signaling sequences within the cytoplasmic
signaling part of the CAR may be linked to each other in a random
or specified order. A short oligo- or polypeptide linker, which is
preferably between 2 and 10 amino acids in length, may form the
linkage. A prominent linker is the glycine-serine doublet.
[0073] As an example, the cytoplasmic domain may comprise the
signaling domain of CD3-zeta and the signaling domain of CD28. In
another example the cytoplasmic domain may comprise the signaling
domain of CD3-zeta and the signaling domain of CD27. In an further
example, the cytoplasmic domain may comprise the signaling domain
of CD3-zeta, the signaling domain of CD28, and the signaling domain
of CD27.
[0074] The CAR of the invention may be designed to comprise any
portion or part of the above-mentioned domains as described herein,
especially in the variants shown in FIG. 2 a-d. The specificity of
the CAR of the invention mediated by the antigen binding domain is
for one or more of the antigens CLA, CD142, CD73, CD49c, CD66c,
CD104, CD318 and TSPAN8 all other domains necessary to construct a
functional CAR may be chosen from the options mentioned above or
which are well known to the person skilled in the art.
Engineered Cells Expressing the Ligand
[0075] In another embodiment of the invention, the ligand is an
engineered cell (or a population thereof), expressing at least one
antigen binding domain specific for one or more antigens selected
from the group consisting of CLA, CD142, CD73, CD49c, CD66c, CD104,
CD318 and TSPAN8.
[0076] In a preferred embodiment, the population of engineered
cells express an ligand like an chimeric antigen receptor (CAR)
comprising an antigen binding domain specific for CLA in
combination with one or more CARs and/or antigens selected from the
group consisting of CD142, CD73, CD49c, CD66c, CD104, CD318 and
TSPAN8.
[0077] The population of engineered cells may consist of T cells,
macrophages or NK cells. The population of engineered cells may be
are expanded to an therapeutically effective amount of cells before
use in said immunotherapy.
[0078] To generate cells expressing the one or more CAR of the
invention (including the variants), a DNA construct encoding the
CAR of the invention can be transfected or transduced into a host
cell by methods well known in the art (e.g. viral-based systems,
physical methods, biological methods, chemical methods). Regardless
of the methods used to integrate the nucleic acid encoding the CAR
of the invention in the host cell, as a result the host cell
expresses a CAR which is specific for the markers as disclosed.
[0079] In one embodiment of the invention, the engineered cells are
isolated (enriched or separated) after the
transfection/transduction process for generating such an engineered
cell from non-transfected/transduced cells by methods well known in
the art, e.g. fluorescent based separating technologies such as
FACS.RTM. or magnetic cell separation methods such as
MACS.RTM..
[0080] In another embodiment of the invention a source of immune
cells, preferentially T cells is obtained from a subject Immune
cells, preferentially T cells can be obtained from a variety of
sources such as peripheral blood mononuclear cells (PMBCs), bone
marrow, lymph node tissue, cord blood or thymus tissue. For
enrichment of these cells methods well known in the art can be used
such as centrifugation through a Ficoll.TM. or PERCOLL.TM. gradient
or positive/negative selection techniques such as fluorescent
sorting (e.g. FACSsort) or magnetic sorting (e.g. MACS.RTM.).
[0081] For example, T cells of a blood sample of a subject are
magnetically labelled, for example with a magnetic bead coupled to
antibodies specific for CD4 and for CD8 or alternatively CD62L,
respectively, washed, magnetically enriched and collected. Then
these T cells may be engineered to express the antigens as
disclosed or the preferred combination of antigens on their cell
surface.
[0082] In one embodiment of the invention the isolated/enriched
engineered T cells expressing an antigens as disclosed or the
preferred combination of antigens prior or after genetic
modification can be activated and expanded to increase amount of
engineered T cells generally using methods well known in the art,
for example polyclonal stimulation with anti-CD3/anti-CD28 beads or
anti-CD3/anti-CD28 nanomatrices (as disclosed in EP2711418A1).
Preferentially, said amount of engineered T cells is increased to a
therapeutic effective amount.
[0083] In one embodiment of the invention a cell expressing the CAR
of the invention is generated. The RNA encoding the CAR of the
invention can be transfected or transduced into a host cell by
methods well known in the art (e.g. viral-based systems, physical
methods, biological methods, chemical methods). In general, such an
"RNA-engineered cell" is disclosed in detail in WO2013/040557.
Regardless of the methods used to integrate the RNA encoding the
CAR of the invention in the host cell, as a result the host cell
expresses a CAR which is specific for an antigen as disclosed or
the preferred combination of antigens. Using "RNA-engineered cells"
lead to the fact that the CAR is expressed for a limited time in
the cell (transient expression).
[0084] In one embodiment of the invention, the engineered cells are
generated automatically in a closed cell culture system. Such
process may comprises the steps: [0085] a) providing a cell sample
[0086] b) preparation of the cell sample by centrifugation [0087]
c) magnetic separation of the cell, preferentially T cells, T cell
subsets or T cell progenitors [0088] d) activation of the enriched
cells, preferentially T cells, T cell subsets or T cell progenitors
using modulatory agents [0089] e) genetically modifying the cells,
preferentially T cells, T cell subsets or T cell progenitors to
express one or more CARs as disclosed or the preferred combination
of CARs/antigens [0090] f) expansion of the genetically modified T
cells, T cell subsets or T cell progenitors
[0091] in a cultivation chamber [0092] g) washing of the cultured
cells, preferentially T cells, T cell subsets or T cell
progenitors. All these steps may be performed in a closed and
sterile system.
[0093] The process is especially suited for preparing gene modified
cells, preferentially T cells, T cell subsets or T cell progenitors
wherein the enriched cells, preferentially T cells, T cell subsets
or T cell progenitors are gene modified by using viral and/or
non-viral vectors. Any of these steps may be multiplied, omitted or
may occur in a different order. In a variant of the invention, the
modulatory agents are selected from agonistic antibodies and/or
cytokines.
[0094] As closed and sterile system for cell modification, the
fully automated cell processing device CliniMACS Prodigy.RTM. and
associated tubing sets (Miltenyi Biotec GmbH, Germany) may be used
(WO2009/072003). This closed system meets the requirements of
GMP-grade processing of almost any kind of cellular products and
may allow reducing clean room requirements, improve technology
transfer and harmonization of cell manufacturing processes. It has
been developed to fully automate and standardize the manufacturing
process of cellular therapeutic agents. The instrument can perform
sample loading, cell washing, density-based cell separations
including erythrocyte reduction and plasma harvesting, magnetic
separation, cell activation, cell modification (transduction), cell
culture, and final product formulation.
[0095] Thus enabling the flexible integration of process modules
("steps") in a closed, automated and safe GMP compliant workflow
reproducing a complex desired biological process.
[0096] In one embodiment of the invention, the genetically modified
cells express one of the targets. To circumvent killing among the
genetically modified cell population, this target is temporarily or
permanently knocked down or knocked out on the killer cells.
Temporal or permanent knock down or knock out of expression can be
induced by methods well known in the art, such as siRNA for
temporal knock down or the CRISPR system for permanent knock out.
To inhibit target expression using these methods, this can be
achieved by directly targeting the whole gene encoding for the
target, parts of the gene, e.g. specific exons, the promotor
region, or controlling genes, such as transcription factors. In the
case of target structures representing glycostructures, such as
CLA, this can also be achieved by altering the glycosylation site
on the backbone protein or one or more of the enzymes catalyzing
the glycosylation.
Methods of Use
[0097] Another embodiment of the invention is a method of binding a
cancer cell with a ligand comprising at least two different antigen
binding domains specific for at least two different antigens
selected from the group consisting of CLA, CD142, CD73, CD49c,
CD66c, CD104, CD318 and TSPAN8. In other words, the cancer cell is
bound with a ligand comprising at two different antigen binding
domains wherein a first antigen binding domain is specific for at
least one antigen selected from the group consisting of CLA, CD142,
CD73, CD49c, CD66c, CD104, CD318 and TSPAN8 and a second antigen
binding domain is specific for at least one other antigen selected
from the group consisting of CLA, CD142, CD73, CD49c, CD66c, CD104,
CD318 and TSPAN8. Preferential combinations comprise CLA with CD66c
and CLA with TSPAN8.
[0098] The ligands according to the invention may be used in
combination with agents, which bind to the antigen and affect the
viability of the cancerous cell expressing this antigen,
preferentially kill the cancerous cell. Examples of such agents are
oncolytic viruses, BiTEs.RTM., ADCCs and immunotoxins.
[0099] An oncolytic virus is a virus that preferentially infects
and kills cancer cells. As the infected cancer cells are destroyed
by lysis, they release new infectious virus particles to help
destroy the remaining tumor. Oncolytic viruses are thought not only
to cause direct destruction of the tumor cells, but also to
stimulate host anti-tumor immune responses. Specific targeting
(e.g. targeting/ligation to the antigens as disclosed) involves
modifying the viral coat proteins to target tumor cells (e.g. with
antigen binding domain specific for antigens as disclosed) while
reducing entry to non-tumor cells.
[0100] Bi-specific T-cell engagers (BiTEs.RTM.) are a class of
artificial bispecific monoclonal antibodies that are investigated
for the use as anti-cancer drugs. They direct a host's immune
system, more specifically the T cells' cytotoxic activity, against
cancer cells. BiTEs are fusion proteins consisting of two
single-chain variable fragments (scFvs) of different antibodies, or
amino acid sequences from four different genes, on a single peptide
chain of about 55 kilodaltons. One of the scFvs binds to T cells
via the CD3 receptor, and the other to a tumor cell via a tumor
specific molecule. Like other bispecific antibodies, and unlike
ordinary monoclonal antibodies, BiTEs.RTM. form a link between T
cells and tumor cells. This causes T cells to exert cytotoxic
activity on tumor cells by producing proteins like perforin and
granzymes, independently of the presence of MHC I or co-stimulatory
molecules. These proteins enter tumor cells and initiate the cell's
apoptosis. This action mimics physiological processes observed
during T cell attacks against tumor cells.
[0101] Antibody-dependent cell-mediated cytotoxicity (ADCC) is a
mechanism of attack by the immune system that requires the presence
of antibodies bound to the surface of target cells. Antibodies are
formed of a binding region (Fab), which binds to the target antigen
and the Fc region that can be detected by immune cells via Fc
receptors on their surface. These Fc receptors are found on the
surface of many cells of the immune system, including natural
killer cells. When a natural killer cell encounter cells coated
with antibodies, the Fc regions interact with their Fc receptors,
leading to the release of perforin and granzyme B. These two
chemicals lead to the tumor cell initiating programmed cell death
(apoptosis). Antibodies known to induce this method of cell killing
include Rituximab, Ofatumumab, Trastuzumab, Cetuximab and
Alemtuzumab. Third generation antibodies that are currently being
developed have altered Fc regions that have higher affinity for a
specific type of Fc receptor, Fc.gamma.RIIIA, which can increase
the rate of ADCC dramatically.
[0102] An immunotoxin is a human-made protein that consists of a
targeting portion linked to a toxin. When the protein binds to that
cell, it is taken in through endocytosis, and the toxin kills the
cell. These chimeric proteins are usually made of a modified
antibody or antibody fragment, attached to a fragment of a toxin.
The "targeting portion" is composed of the Fv portion of an
antibody that binds specifically to an antigen expressed by a cell,
preferably by a specific cell type. The toxin is usually a
cytotoxic protein derived from a bacterial or plant protein, from
which the natural binding domain has been removed so that the Fv
directs the toxin to the antigen on the target cell.
Pharmaceutical Composition
[0103] Another object of the invention is a pharmaceutical
composition comprising a population of engineered cells expressing
a CAR as already disclosed, optionally with a pharmaceutical
acceptable carrier like Composol or NaCl solution.
Use for Treatment of Cancer
[0104] The population of engineered cells as disclosed and/or the
pharmaceutical composition comprising the population of engineered
cells may be used in a method for treatment of human cancer with
cells expressing the disclosed target molecules, especially of
human pancreas cancer.
[0105] The pharmaceutical composition comprises preferable a
population of engineered cells expressing a CAR as already
disclosed according to any of claims 1 to 7. In a variant of the
invention, the pharmaceutical composition is used in combination
with a chemotherapeutic, radiation, or immunomodulatory agent for
treatment of cancer.
[0106] The cancer to be treated may include hematopoietic cancer,
myelodysplastic syndrome, pancreatic cancer, head and neck cancer,
cutaneous tumors, minimal residual disease (MRD) in acute
lymphoblastic leukemia (ALL), acute myeloid leukemia (AML), lung
cancer, breast cancer, ovarian cancer, prostate cancer, colon
cancer, melanoma or other hematological cancer and solid tumors, or
any combination thereof. In another embodiment, the cancer includes
a hematological cancer such as leukemia (e.g., chronic lymphocytic
leukemia (CLL), acute lymphocytic leukemia (ALL), acute myeloid
leukemia (AML), or chronic myelogenous leukemia (CML), lymphoma (e
g, mantle cell lymphoma, non-Hodgkin's lymphoma or Hodgkin's
lymphoma) or multiple myeloma, or any combination thereof.
Furthermore, the cancer may include an adult carcinoma comprising
coral and pharynx cancer (tongue, mouth, pharynx, head and neck),
digestive system cancers (esophagus, stomach, small intestine,
colon, rectum, anus, liver, intrahepatic bile duct, gallbladder,
pancreas), respiratory system cancers (larynx, lung and bronchus),
bones and joint cancers, soft tissue cancers, skin cancers
(melanoma, basal and squamous cell carcinoma), pediatric tumors
(neuroblastoma, rhabdomyosarcoma, osteosarcoma, Ewing's sarcoma),
tumors of the central nervous system (brain, astrocytoma,
glioblastoma, glioma), and cancers of the breast, the genital
system (uterine cervix, uterine corpus, ovary, vulva, vagina,
prostate, testis, penis, endometrium), the urinary system (urinary
bladder, kidney and renal pelvis, ureter), the eye and orbit, the
endocrine system (thyroid), and the brain and other nervous system,
or any combination thereof.
[0107] The treatment of cancer may encompass any method which
involves at least one antigen as disclosed or any combination of
antigens as disclosed as target molecule. Such methods may be e.g.
treatment with agents which bind to the antigen and affect the
viability of the cancerous cell expressing this antigen,
preferentially kill the cancerous cell. Examples are oncolytic
viruses, BiTEs.RTM., ADCCs and immunotoxins as already
disclosed.
[0108] For the treatment, immune cells, e.g. T cells of a subject
may be isolated. The subject may suffer from said cancer or may be
a healthy subject. These cells are genetically modified in vitro or
in vivo to express one or more CARs of the invention. These
engineered cells may be activated and expanded in vitro or in vivo.
In a cellular therapy these engineered cells may be infused to a
recipient in need thereof. These cells may be a pharmaceutical
composition (said cell plus pharmaceutical acceptable carrier). The
infused cells are able to kill (or at least stop growth of)
cancerous cells expressing one or more of the disclosed antigens in
the recipient. The recipient may be the same subject from which the
cells was obtained (autologous cell therapy) or may be from another
subject of the same species (allogeneic cell therapy).
[0109] In one embodiment of the invention the subject suffering
from pancreas cancer may be treated with the pharmaceutical
composition of the invention together with an immunomodulatory
agent, such as but not limited to Rapamycin or agents blocking
PD-1/PD-L1 or CTLA4 signaling.
[0110] In one embodiment of the invention, due to the fact that the
cancerous cells expressing one or more of the disclosed antigens
may be only a subpopulation of the cancerous cells of the subject
the subject may be treated additionally with chemotherapy or
radiotherapy. Chemotherapeutic and radiation agents suited to treat
cancers are well known in the art.
[0111] In one embodiment of the invention the CAR expressing cells
are applied to a subject suffering from cancer, especially pancreas
cancer as cellular therapy as disclosed above but in combination
with a second activating CAR, which is also expressed on the same
engineered cells, recognizing an additional epitope on the
cancerous cells expressing one or more of the disclosed antigens to
increase the specificity of the engineered cells expressing both
CARs. This epitope can be membrane bound, part of the extracellular
matrix, or a soluble component.
[0112] In one embodiment of the invention the CAR expressing cells
are applied to a subject suffering from cancer as cellular therapy
as disclosed above but in combination with a second, inhibitory
CAR, which is also expressed on the same engineered cells,
recognizing an additional epitope to increase the specificity of
the engineered cells expressing both CARs. This epitope can be
membrane bound, part of the extracellular matrix, or a soluble
component.
[0113] The immune cells, preferentially T cells engineered to
express one or more of the disclosed antigens may be administered
either alone, or as a pharmaceutical composition in combination
with diluents and/or with other components such as IL-2 or other
cytokines or cell populations. Briefly, pharmaceutical compositions
of the present invention may comprise a cell population of
genetically modified cells as described herein, in combination with
one or more pharmaceutically or physiologically acceptable
carriers, diluents or excipients. Such compositions may comprise
buffers such as neutral buffered saline, phosphate buffered saline
and the like; carbohydrates such as glucose, mannose, sucrose or
dextrans, mannitol; proteins;
[0114] polypeptides or amino acids such as glycine; antioxidants;
chelating agents such as EDTA or glutathione; adjuvants (e.g.,
aluminum hydroxide); and preservatives.
[0115] Preferentially, the compositions of the present invention
are formulated for intravenous administration. The administration
of cell compositions to the subject may be carried out in any
convenient manner known in the art.
[0116] Pharmaceutical compositions of the present invention may be
administered in a manner appropriate to the disease to be treated.
Appropriate dosages may be determined by clinical trials. But the
quantity and frequency of administration will also be determined
and influenced by such factors as the condition of the patient, and
the type and severity of the patient's disease.
[0117] A pharmaceutical composition comprising the immune cells,
preferentially T cells disclosed herein may be administered at a
dosage of 10.sup.4 to 10.sup.9 cells/kg body weight, preferably
10.sup.5 to 10.sup.6 cells/kg body weight. The cell compositions
may also be administered several times at these dosages. The
compositions of cells may be injected directly into a tumor, lymph
node, or site of infection.
EXAMPLES
[0118] The following examples are intended for a more detailed
explanation of the invention but without restricting the invention
to these examples.
Example 1: Expression of Targets on Pancreatic Cancer
[0119] Expression of CLA, CD142, CD73, CD49c, CD66c, CD104, CD318
and TSPAN8 on xenotransplanted human pancreatic cancer cells
indicates the strong abundance of these markers on pancreatic
cancer cells independent on the tumor microenvironment (FIG. 3). In
addition, all markers are also reproducibly expressed at high
levels on primary human pancreatic cancer cells (marked Epcam+) but
neither on healthy tumor infiltrating leukocytes (marked CD45+)
cells nor on other healthy tissue resident cell types (marked
Double negative) (FIG. 4). These results were further validated
using immunohistochemistry based detection of target expression in
human pancreas cancer (FIG. 5).
Example 2: Structure of a CAR Recognizing Pancreas Cancer Specific
Targets
[0120] The linkers used may comprise an epitope/tag allowing for
the detection of the CAR as shown in FIG. 1. Examples for
epitopes/tags are YOL, cMYC, or HIS. The pancreas cancer target
specific binding fragment is derived from one or several antibodies
specific for CLA, CD142, CD73, CD49c, CD66c, CD104, CD318 and/or
TSPAN8. The hinge region may be derived e.g. from IgG domains,
CD8a, or CD28 and may comprise an epitope/tag allowing for the
detection of the CAR. The transmembrane domain may be derived e.g.
from CD8a or CD28 followed by one to three signaling domains. These
domains may be derived e.g. from CD28, 4-1BB, OX40, or CD3
zeta.
Example 3: Structure of Dual CAR Recognizing Pancreas Cancer
Specific Targets
[0121] Recognition of two or more targets can be solved by either
combining multiple antigen binding sites on one CAR molecule or by
using multiple CAR molecules which are expressed in one cell and
only work in combination, e.g. by using signaling domains for each
of the CAR constructs that are inefficient for cell activation when
used alone (FIG. 2).
Example 4: Amino Acid Sequence of the CLA Specific Antibody
[0122] The amino acid sequences of the variable portions of the
immunoglobulin heavy chain and light chain of the used antibody
specifically binding to CLA were as given in SEQ ID NO:1 and SEQ ID
NO:2, respectively. The relevant sites causing specificity for
antigen binding are the CDRs according to the IMGT (the
international ImMunoGeneTics information system for immunoglobulins
or antibodies) definition which are underlined in the sequence.
These sequences or any sequences derived thereof with a specificity
for CLA can be used to generate a CAR recognizing CLA. The
sequences given in SEQ ID NO:1 and SEQ ID NO:2 are only exemplary
for sequences which are specific for the antigen CLA (the sequences
are given in one letter code for amino acids). Other sequences may
be used for generating antigen binding domains of an antibody or of
a CAR which are also specific for the antigen CLA.
Example 5: Amino Acid Sequence of the CD142 Specific Antibody
[0123] The amino acid sequences of the variable portions of the
immunoglobulin heavy chain and light chain of the used antibody
specifically binding to CD142 were as given in SEQ ID NO:3 and SEQ
ID NO:4, respectively. The relevant sites causing specificity for
antigen binding are the CDRs according to the IMGT (the
international ImMunoGeneTics information system for immunoglobulins
or antibodies) definition which are underlined in the sequence.
These sequences or any sequences derived thereof with a specificity
for CD142 can be used to generate a CAR recognizing CD142. The
sequences given in SEQ ID NO:3 and SEQ ID NO:4 are only exemplary
for sequences which are specific for the antigen CD142 (the
sequences are given in one letter code for amino acids). Other
sequences may be used for generating antigen binding domains of an

Example 12: Validation of CAR Expression
[0130] 75.000 HEK 293T cells were inoculated in an 48-well. Cells
were transfected with 0.5 .mu.g plasmid using the MACSfectin
transfection protocol 24 h later. Cells were detached 48 h post
transfection using PBS supplemented with 1 mM EDTA. One third of
the cells transfected with one plasmid was stained with an
Anti-CD271 antibody (Miltenyi Biotec GmbH) following the
recommended protocol. Another third was incubated 30 min at
4.degree. C. with an Anti-Mouse IgG (Fab specific) antibody
produced in goat (Sigma Aldrich) with 10 .mu.g/ml antibody
concentration. After a washing step cells were incubated with an
Anti-Goat IgG (H+L) Cross-Adsorbed Secondary Antibody produced in
chicken (Thermo Fisher Scientific) for 30 min at 4.degree. C. with
10 .mu.g/ml antibody concentration. The last third was stained
solely as described with the secondary antibody as a background
control. Samples were measured using a MACSQuant 10 analyzer. FIG.
6 A shows the percentage of cells expressing LNGFR on the surface
as a readout of transfection efficacy and construct expression.
FIG. 6 B shows the percentage of cells expressing the CAR construct
on the surface. With few exceptions, all CAR molecules could be
successfully expressed.
Example 13: Generation of Lentiviral Expression Vectors
[0131] The pancreas cancer specific CARs were cloned into third
generation SIN-lentiviral vector constructs under the control of
the human PGK promoter. Transient transfection of HEK 293T cells
with this expression plasmid and further plasmids encoding the
structural proteins gag-pol, rev and VSV-G envelope protein
resulted in the release of viral vector particles into the
supernatant. The viral vector particles were subsequently enriched
by low speed centrifugation and stored at -70.degree. C.
Example 14: T Cell Separation and Genetic Modification with
Pancreas Cancer Specific CARs
[0132] Primary T cells were isolated from donor apheresis or buffy
coat samples using MicroBeads and MACS Technology.RTM. (Miltenyi
Biotec GmbH, Germany) to reach purities of over 90% (CD3+ cells).
Magnetically enriched cells were washed and resuspended in TexMACS
medium supplemented with 200 IU/mL human recombinant IL-2 (Miltenyi
Biotec GmbH, Germany). The T cells were then stimulated by addition
of the GMP TransAct CD3/CD28 Reagent (Miltenyi Biotec GmbH,
Germany).
[0133] After 24 hours, successful T cell stimulation was confirmed
by staining the T cells with CD25 and CD69 antibodies and analysis
by flow cytometry in a MACSQuant Analyzer (Miltenyi Biotec GmbH,
Germany). The stimulated T cells were then transduced by adding
lentiviral vectors encoding pancreas cancer specific CARs at an
MOI=0.5-2. After 4 days of static culture the cells were washed to
remove excess viral vector and TransAct Reagent and were cultivated
for a further 5-10 days. The efficiency of viral transduction was
measured by staining the surface expression of pancreas cancer
specific CARs among live CD3+ cells using anti-human Fc
fluorochrome and flow cytometry. The number of gene marked T cells
ranged between 10 and 60%, depending on the MOI used.
Example 15: Pancreas Cancer Specific CARs Functionality
[0134] Cells expressing one or more of the pancreas cancer specific
targets or cells not expressing these targets were incubated for 5
or 24 hours with expanded T cells expressing pancreas cancer
specific CARs or, as a control, with non-transduced T cells at
varied effector to target cell ratios. Specific target cell killing
was analyzed by flow cytometry. Alternatively, the effector cells
were restimulated with cell lines which were target-positive or
-negative. Cytokine production (IFN-.gamma., IL-2, TNF-.alpha.) as
well as degranulation (CD107a) were analyzed by flow cytometry.
Only T cells carrying the pancreas cancer specific CARs were able
to kill the target cells, showed increased cytokine production as
well as degranulation marker upregulation.
[0135] Furthermore, the killing efficacy and kinetics were analyzed
by long-term co-culture of CAR T cells and pancreatic cancer cells.
T cells were isolated from a whole blood donation of a healthy
donor using the Pan T Cell Isolation Kit (Miltenyi Biotec, Germany)
Isolated T cells were activated in TexMACS.TM. GMP medium (Miltenyi
Biotec, Germany) supplemented with 40 IU/ml IL-2 (Miltenyi Biotec,
Germany) using MACS GMP T Cell TransAct (Miltenyi Biotec, Germany)
After 24 h T cells were transduced with lentiviral vectors
containing the CAR constructs at an MOI of 2. Subsequently, T cells
were cultivated in TexMACS.TM. GMP medium supplemented with 40
IU/ml IL-2. On day 12 post transduction CAR expression was assessed
via flow cytometric measurement of the reporter protein LNGFR. CAR
positive T cells were adjusted to same numbers and inoculated in 96
well plates with pancreatic adenocarcinoma cell line BxPC3 in 200
.mu.l TexMACS.TM. GMP medium. Prior to this assay, BxPC3 cells were
transduced with lentiviral vectors containing GFP. GFP positive
cells were tracked and analyzed using the IncuCyte S3 (Essen
BioScience, Germany). The "Green Object confluence" was used as a
read out as it inversely correlates with the specific lysis of GFP
expressing adherent target cells. All CAR constructs mediated
efficient killing of tumor cells as compared to the mock control.
Results are shown in FIG. 7.

Example 24: Co-Expression of CLA and CD142, CD73, CD49c, CD66c,
CD104, CD318 and TSPAN8 on Primary Human Pancreatic Cancer
Cells
[0144] Human pancreas adenocarcinoma tissue was dissociated,
stained and analyzed. FIG. 6A shows the general gating strategy:
after debris exclusion dead cells were excluded with a propidium
iodide staining. Unwanted doublets were excluded by plotting the
height against the area for forward scatter. EpCAM+, CD45+ as well
as CD45-/EpCAM- cells were discriminated and further analyzed with
PE or APC conjugated antibodies specific for the targets. FIG. 6B
shows co-expression of CLA and CD142, CD73, CD49c, CD66c, CD104,
CD318 and TSPAN8 on primary human pancreatic cancer cells. The
results indicate a strong co-expression among these markers which
is a pre-requisite for dual targeting (FIGS. 8 A and B).
