FIELD
[0003] The present disclosure relates to compositions comprising
tumor infiltrating
lymphocytes (TILs) and methods of culturing the cells. In some aspects, the
methods disclosed
herein preferentially promote the enrichment of oligoclonal or polyclonal
tumor reactive (e.g.,
tumor specific) stem-like T-cells, e.g., TILs characterized by being less
differentiated. Cells
cultured using the methods disclosed herein can be used for various cell
therapies, including, but
not limited, to adoptive cell therapies such as autologous T cell therapies.
BACKGROUND
[0004] The use of immunotherapy strategies has demonstrated
considerable clinical
efficacy in the treatment of certain types of advanced cancer. However, in
spite of notable
successes, the vast majority of patients with advanced cancers still do not
benefit from
immunotherapy treatments and will eventually succumb to their illness. A key
limitation to cell
therapy techniques such as adoptive cell therapies including chimeric antigen
receptor (CAR) and
engineered TCR T cells is a lack of suitable tumor targets, which may
contribute to the lack of
widespread clinical responses observed in patients with solid cancers that
have been treated with,
e.g., CAR T cells.
[0005] Another approach that has had some success in mediating
clinical response in
patients with advanced cancer is the isolation, expansion, and infusion of
autologous tumor
infiltrating lymphocytes (TILs). TILs are heterogenous, with variable
compositions of tumor-

WO 2023/077034
PCT/US2022/078827

reactive and irrelevant or suppressive T cells. The tumor-reactive populations
are frequently highly
antigen-experienced, resulting in cell products that are in a pre-
dysfunctional state with limited
functionality.
[0006] Traditional methods of culturing and expanding TILs have
been found to lead to
terminal differentiation of the TILs, resulting in poor persistence of the
TILs upon transfer to
patients. See, e.g., Rosenberg et al., Clinical Cancer Research 17(13): 4550-
557 (2011). Further,
current methods of expanding heterogenous TIL populations from tumor fragments
yield
populations of TILs with reduced polyclonality and the loss of many tumor-
dominant T cell clones
(see, e.g., Poschke, et al,, Clin. Cancer Res. (2020), which is incorporated
by reference herein in
its entirety). As a result, generating such TIL-derived infusion products
often results in loss of
tumor-specific T cells during expansion and an ill-defined mix of immune cells
at various states of
differentiation, which are ineffective at eradicating solid tumors. To be
curative, TILs with
enhanced self-renewing stem/effector properties are needed. Moreover, methods
have not yet been
described for obtaining an expanded population of less-differentiated TILs
with a high level of
clonal diversity that retain the ability to further divide and target and kill
cancer cells.
[0007] To date, these and other critical limitations have
curtailed the use of TILs as an
effective therapeutic, making it difficult to obtain a sufficient number of
tumor-reactive TILs for
use in T cell therapy. As such, there remains a need in the art for improved
methods of preparing
TIL compositions and therapies using the same.

[0140] Units, prefixes, and symbols are denoted in their Systeme
International de Unites
(SI) accepted form. Numeric ranges are inclusive of the numbers defining the
range.
[0141] Abbreviations used herein are defined throughout the
present disclosure. Various
aspects of the disclosure are described in further detail in the following
subsections.
[0142] The terms "about" or "comprising essentially of' refer to
a value or composition
that is within an acceptable error range for the particular value or
composition as determined by
one of ordinary skill in the art, which will depend in part on how the value
or composition is
measured or determined, i.e., the limitations of the measurement system. For
example, "about" or
"comprising essentially of' can mean within 1 or more than 1 standard
deviation per the practice
in the art. Alternatively, "about" or "comprising essentially of' can mean a
range of up to 10%.
Furthermore, particularly with respect to biological systems or processes, the
terms can mean up
to an order of magnitude or up to 5-fold of a value. When particular values or
compositions are
provided in the application and claims, unless otherwise stated, the meaning
of "about" or
"comprising essentially of' should be assumed to be within an acceptable error
range for that
particular value or composition.
[0143] As used herein, the term "approximately," as applied to
one or more values of
interest, refers to a value that is similar to a stated reference value. In
some aspects, the term
"approximately" refers to a range of values that fall within 10%, 9%, 8%, 7%,
6%, 5%, 4%, 3%,
2%, 1%, or less in either direction (greater than or less than) of the stated
reference value unless
otherwise stated or otherwise evident from the context (except where such
number would exceed
100% of a possible value).
[0144] As described herein, any concentration range, percentage
range, ratio range or
integer range is to be understood to include the value of any integer within
the recited range and,
when appropriate, fractions thereof (such as one tenth and one hundredth of an
integer), unless
otherwise indicated.
[0145] The term "control media" as used herein refers to any
media in comparison to the
metabolic reprogramming media ("MRM") disclosed herein. Control media can
comprise the same
components as the metabolic reprogramming media except certain ion
concentrations, e.g,
potassium ion. In some aspects, metabolic reprogramming media described herein
are prepared
from control media by adjusting one or more ion concentrations, e.g.,
potassium ion concentration,
as described herein. In some aspects, control media comprise basal media,
e.g., CTSTm
OPTIMIZERTm. In some aspects, control media comprise AIM V, RPMI, or a mixture
comprising
AIM V and RPMI. In some aspects, control media comprise (i) 50% AIM V, (ii)
50% RPMI1640,

thus comprises one or
more additional components, including, but not limited to, amino acids,
glucose, glutamine, T cell
stimulators, antibodies, substituents, etc. that are also being added in the
metabolic reprogramming
media, but control media have certain ion concentrations different from the
metabolic
reprogramming media. Unless indicated otherwise, the terms "media" and
"medium" can be used
interchangeably.
[0146] As used herein, a "control process" or an "MRM process"
refers to a method
disclosed herein, wherein the TIL culturing and expansion process includes a
control medium, or
an MR1\4 medium, respectively. As such, a "control process" refers to the
culturing of Tits in a
control medium disclosed herein, such as AIIVI V or TCM without a modified
concentration of
potassium (i.e., less than 40 mM, e.g., 5 mM, potassium ion), and an "MR_I\4
process" refers to the
culturing of TILs in an MRI\4 medium disclosed herein.
[0147] As used herein, the term "immune cell" refers to a cell
of the immune system. In
some aspects, the immune cell is selected from a T lymphocyte ("T cell"), B
lymphocyte ("B cell"),
natural killer (INK) cell, macrophage, eosinophil, mast cell, dendritic cell
or neutrophil). In some
aspects, the immune cell is a tumor-infiltrating cell (TIL). As used herein, a
"TIL" refers to T cell
that has at least once entered into a tumor or is capable of entering a tumor,
e.g., within the
parenchyma of a tumor. In some aspects, the tumor is a solid tumor. In some
aspects, the tumor is
a liquid tumor, e.g., a hematopoietic cancer. TILs prepared by the present
methods can have one
or more properties that are the same as the naturally occurring TILs. In some
aspects, TILs prepared
by the present methods have one or more properties that are not present in the
naturally occurring
TILs. TILs can be obtained using any methods. In some aspects, the TILs are
obtained from a
tumor sample from a subject. In some aspects, the tumor sample, or a portion
thereof, is cultured
under conditions that promote evasion of the TILs from the tumor tissue,
proliferation of the TILs,
and/or expansion of the TILs. In some aspects, the medium used to promote
evasion, proliferation,
and/or expansion of the TILs is any metabolic reprogramming medium, e.g.,
hyperkalemic
medium, disclosed herein.
[0148] As used herein, a "population" of cells refers to a
collection of more than one cell,
e.g., a plurality of cells. In some aspects, the population of cells comprises
more than one TILs,
e.g., a plurality of TILs In some aspects, the population of cells is
comprises a heterogeneous
mixture of cells, comprising multiple types of cells, e.g., a heterogeneous
mixture of TILs and cells
other than TILs.

[0149] TILs include, but are not limited to, CD8+ T cells (i.e.
cytotoxic T cells), CD4+ T
cells, B cells, and natural killer cells. TILs include both primary (e.g.,
obtained from a patient tissue
sample) and secondary TILs (e.g., TIL cell populations that have been
cultured, expanded or
proliferated from primary TILs. In some aspects the TILs are genetically
modified. In some
aspects, the TIL is a CD8+ T cell. CD8+ TILs are generally considered to be
the subpopulation of
TILs responsible for destroying cancer cells. Conversely, CD4+ TILs are
generally considered to
act as suppressors of the immune response, which can limit the immune response
against the tumor.
[0150] In some aspects, TILs can be defined biochemically using
cell surface markers.
TILs can be generally categorized by expressing one or more of the following
biomarkers: CD4,
CD8, TCR c43, CD27, CD28, CD56, CCR7, CD45RA, CD95, PD-1, and CD25. In some
aspects,
TILs can be defined functionally by their ability to infiltrate tumors and
selectively kill the cancer
cells.
[0151] As used herein, the terms "T cell" and "T lymphocyte" are
interchangeable and refer
to any lymphocytes produced or processed by the thymus gland. Non-limiting
classes of T cells
include effector T cells (such as CD8+ T cell) and Th cells (such as CD4+ T
cells). In some aspects,
the immune cell is a Thl cell. In some aspects, the immune cell is a Th2 cell.
In some aspects, the
immune cell is a Tc17 cell. In some aspects, the immune cell is a Th17 cell.
In some aspects, the
immune cell is a Trcg cell.
[0152] As used herein, the term "memory" T cells refers to T
cells that have previously
encountered and responded to their cognate antigen (e.g., in vivo, in vitro,
or ex vivo) or which
have been stimulated with, e.g., an anti-CD3 antibody (e.g., in vitro or ex
vivo). Immune cells, e.g.,
TILs, having a "memory-like" phenotype, upon secondary exposure to antigen or
stimulation,
reproduce or proliferate to mount a faster and strong immune response than
during the primary
exposure. In some aspects, memory T cells comprise central memory T cells (Tcm
cells), effector
memory T cells (TEm cells), tissue resident memory T cells (TRm cells), stem
cell-like memory T
cells (Tscm cells), or any combination thereof
[0153] As used herein, the term "stem-like" or "stem cell-like"
refers to a property or an
ability of a cell to self-renew and has the multipotent capacity to generate
and reconstitute the entire
spectrum of memory and effector T cell subsets. In some aspects, a stem-like
cell can be measured
by specific markers expressed by the cell. In some aspects, those stem-like
markers can be one or
more of CD45RA+, CD62L+, CCR7-1, CD27-1, CD28+, BACH2+, LEF1+, and TCF7+. In
some
aspects, stem-like cells can be identified based on CD39- and CD69-
expression. As will be evident
to those skilled in the arts, the symbol "-" adjacent to a marker (e.g., CD39-
) does not necessarily
CA 03234821 2024-4- 11

WO 2023/077034
PCT/US2022/078827
- 34 -
indicate that a cell completely lacks the expression of the marker. For
instance, in some aspects,
CD39- cells can have some CD39 expression but the expression is much reduced
as compared to
a reference cell, e.g., CD39+ cell. Therefore, unless indicated otherwise,
"CD39- cells" can
comprise cells with no expression of CD39 as well as cells with reduced CD39
expression as
compared to a reference cell, e.g., CD39+ cells. As shown in FIG. 55, CD39-
CD69- cells (i.e.,
stem-like cells) can be identified using flow cytometry. For instance, the
CD39- CD69- cells can
be identified by first gating on the CD8+ or CD4+ T cells (see left flow
plot). Then, the CD39+
CD69+ cells are identified within the CDS+ or CD4+ T cell population (see
upper right quadrant
in the right flow plot). The CD39- CD69- cells correspond to the bottom left
two boxes (see the
two arrows). (Krishna et al., Science 370:1328-34 (Dec. 11, 2020); and/or
Galletti et al., Nature
Immunology (October 2018). In some aspects, CD39 dim/- CD69- stem-like TIL can
be gated with
the use of fluorescent minus one (FMO) controls to determine upper boundary
for background
signal for both CD39 and CD69. Populations that fall within the FMO boundary
are considered as
negative expression for the associated marker. Using FMO boundaries,
populations are gated for
CD39 dim/- CD69- expression. CD39 gates are extended slightly past the FMO
boundary to
include CD39 dim cells that remained CD69-. In some aspects, stem-like cells
can be identified
based on one or more of the following: CD45RA+, CD62L+, CCR7+, CD27+, CD28+,
BACH2+,
LEF1+, TCF7+, CD39-, and CD69-. In some aspects, the stem-like cells can be
identified by a
transcriptome analysis (alone or in combination with the phenotypic markers
described above),
e.g., using sternness gene signatures disclosed herein. In some aspects, the
effector-like marker
comprises a marker disclosed in Krishna et al., Science 370:1328-34 (Dec. 11,
2020); and/or
Galletti et al., Nature Immunology (October 2018), each of which is
incorporated by reference
herein in its entirety.
[0154] As used herein, the term "stem cell-like memory T cells,"
"T memory stem cells,"
or "Tscm cells" refer to memory T cells that express CD95, CD45RA, CCR7, and
CD62L and are
endowed with the stem cell-like ability to self-renew and the multipotent
capacity to reconstitute
the entire spectrum of memory and effector T cell subsets.
[0155] As used herein, the term "central memory T cells" or "Tcm
cells" refer to memory
T cells that express CD45RO, CCR7, and CD62L. Central memory T cells are
generally found
within the lymph nodes and in peripheral circulation.
[0156] As used herein, the term "effector-like" or "effector
cell-like" refers to tumor cell
killing capacity and cytokine polyfunctionality, e.g., ability of a cell to
produce inflammatory
cytokines and/or cytotoxic molecules. In some aspects, an effector-like cell
can be measured by

[0158] As used herein, the term "effector memory T cells" or
"TEm cells" refer to memory
T cells that express CD45R0 but lack expression of CCR7 and CD62L Because
effector memory
T cells lack lymph node-homing receptors (e.g., CCR7 and CD62L), these cells
are typically found
in peripheral circulation and in non-lymphoid tissues.
[0159] As used herein, the term "tissue resident memory T cells"
or "TRm cells" refer to
memory T cells that do not circulate and remain resident in peripheral
tissues, such as the skin,
lung, and the gastrointestinal tract. In some aspects, tissue resident memory
T cells are also effector
memory T cells

[0160] As used herein, the term "naive T cells," "TN cells," or
"naive" TILs" refers to T
cells and/or TILs that express CD45RA, CCR7, and CD62L, but which do not
express CD95.
These cells represent the most undifferentiated cell in the T cell lineage.
The interaction between
a naive T cell and an antigen presenting cell (APC) induces differentiation of
the naive T cell
towards an actiaved TEFF cell and an immune response.
[0161] As used herein, the term "fragmenting," "fragment," and
"fragmented" describe
processes for disrupting a tumor, including mechanical fragmentation methods
such as crushing,
slicing, dividing, and morcellating tumor tissue as well as any other methods
for disrupting the
physical structure of tumor tissue.
[0162] The term "culturing" as used herein refers to the
controlled growth of cells ex vivo
and/or in vitro. As used herein, "culturing" includes the growth of cells,
e.g., TILs, during cell
expansion. In some aspects, the cultured cells are obtained from a subject,
e.g., a human subject.
In some aspects, the cultured cells comprise TILs obtained from a human
subject. In some aspects,
the culturing comprises placing a tumor sample or tumor fragmentinto a medium
disclosed herein,
wherein the medium promotes TIL evasion from the tumor sample and TIL
expansion. In some
aspects, the tumor sample or tumor fragement is a dissociated tumor sample
(e.g., single cell
suspension). In some aspects, the dissociated tumor sample (e.g., single cell
suspension) is
dissociated in a medium disclosed herein. In some aspects, the culturing
comprises placing a
dissocoiated tumor sample or tumor fragment into a medium disclosed herein. In
some aspects, the
TILs are isolated or purified prior to the culture. In some aspects, the cell
culturing is intended to
expand the number of cultured cells, e.g., to increase proliferation of the
cells.
[0163] "Expand" or "expansion," as used herein in reference to
TILs refers to the process
of stimulating or activating the cells and culturing the cells. The expansion
process can lead to an
increase in the proportion or the total number of desired cells, e.g., an
increase in the proportion or
total number of TILs, in a population of cultured cells, after the cells are
stimulated or activated
and cultured. Expansion does not require that all cell types in a population
of cultured cells are
increased in number. Rather, in some aspects, only a subset of cells in a
population of cultured
cells are increased in number during expansion, while the number of other cell
types may not
change or may decrease.
[0164] As used herein, the term "yield" refers to the total
number of cells following a
culture method or a portion thereof. In some aspects, the term "yield" refers
to a particular
population of cells, e.g., stem-like TILs in a population of Tits. The yield
can be determined using
any methods, including, but not limited to, estimating the yield based on a
representative sample.

[0165] As used herein, the term "stem cell-like," "stem-like,"
or "less-differentiated" refers
to a cell, e.g., an immune cell (e.g., a TIL), that expresses markers
consistent with a more naive
phenotype. For example, a less differentiated TIL can express one or more
markers characteristic
of a TN or a Tscm cell. In some aspects, a "less-differentiated" or "stem-
like" TIL expresses
CD45RA, CCR7, and CD62L. In some aspects, a "less-differentiated" or "stem-
like" TIL expresses
CD45RA, CCR7, and CD62L, and is CD45R010w. In some aspects, a "less-
differentiated" or "stem-
like" immune cell (e.g., TIL) expresses CD45RA, CCR7, and CD62L, and does not
express
CD45RO. In some aspects, a "less-differentiated" or "stem-like" T cell
expresses CD45RA, CCR7,
CD62L, and TCF7. In some aspects, the methods disclosed herein promote the
growth and/or
proliferation of cells, e.g., TILs, having a less-differentiated phenotype.
Without being bound by
any particular mechanism, in some aspects, the methods disclosed herein block,
inhibit, or limit
differentiation of less-differentiated cells, e.g., TILs, resulting in an
increased number of stem-like
cells in culture. For example, it is generally thought that to effectively
control tumors, adoptive
transfer of less-differentiated TILs with a stem cell-like memory or central
memory phenotype are
preferred. See, e.g., Gattinoni, L., et al., J. Cl/n. Invest. 115:1616-
1626(2005); Gattinoni, L., et al.

[0166] Stemness is characterized by the capacity to self-renew,
the multipotency, and the
persistence of proliferative potential. In some aspects, sternness is
characterized by a particular
gene signature, e.g., a combined pattern of expression across a multitude of
genes. In some aspects,
the gene signature comprises one or more genes selected from ACTN1, DSCI,

[0167] In the presence of prolonged antigen exposure, such as in
many cancers, more
differentiated immune cells, e.g., effector and effector memory T cells, often
become exhausted
and lose their anti-tumor function. Biomarkers, e.g., T cell markers, can be
measured using any
methods. In some aspects, T cells are identified using antibody-staining
following by gated flow
cytometry.
[0168] The term "clonotype," as used herein, refers to a
population of T cells with unique
DNA sequences that result from TCRa or TCRB rearrangements. A unique variable
a chain (VA)
sequence may pair up with more than one variable 13 chain (VB) sequence.
Conversely, a unique
VB sequence may pair up with more than one VA sequence.
[0169] As used herein, the term "tonicity" refers to the measure
of the effective osmotic
pressure gradient across a cell membrane. Tonicity can be measured or
calculated based on the
CA 03234821 2024-4- 11

WO 2023/077034

-40 -
level of potassium ion and sodium chloride (NaCl) in a solution. Herein,
tonicity is calculated as
the sum of the concentration of potassium ion (K+) and the concentration of
sodium chloride
(NaCl), multiplied by two. Tonicity can be expressed in terms of the
osmolality of the solution,
e.g., the media. As used herein, a solution, e.g., medium, is considered
"isotonic" when the
concentration of solutes in the media is equivalent to the concentration of
solutes inside the cell.
As used herein, an isotonic medium has an osmolality of about 280 mOsm/L
(e.g., ([K ] I [NaCl])
X 2 = 280).
[0170] As used herein, a solution, e.g., a medium, is considered
"hypotonic" if the
concentration of solutes in the solution is lower than the concentration of
solutes in the cell. As
used herein, a hypotonic solution has a tonicity of less than 280 mOsm/L
(e.g., ([K+] + [NaCl]) X
2 <280). In some aspects, a hypotonic medium described herein has an
osmolality of about 240
mOsm/L or about 250 mOsm/L. In some aspects, a hypotonic medium has a tonicity
from at least
about 220 mOsm/L to less than about 280 mOsm/L. In some aspects, a hypotonic
medium has a
tonicity from at least about 230 mOsm/L to less than about 280 mOsm/L. In some
aspects, a
hypotonic medium has a tonicity from at least about 240 mOsm/L to less than
about 280 mOsm/L.
In some aspects, a hypotonic medium described herein has a tonicity of about
250 mOsm/L (e.g.,
([K+] + [NaCl]) X 2 = 250).
[0171] As used herein, a solution, e.g., a medium, is considered
"hypertonic" if the
concentration of solutes in the solution is higher than the concentration of
solutes in the cell. As
used herein, a hypertonic solution has an osmolality of greater than 300
mOsm/L (e.g., ([K+] +
[NaCl]) X 2 > 280). In some aspects, a hypertonic medium described herein has
an osmolality of
about 320 mOsm/L. In certain aspects, the tonicity of the solution, e.g.,
medium is adjusted by
increasing or decreasing the concentration of one or more solute selected from
potassium ions,
sodium ions, glucose, and any combination thereof. In some aspects, the
tonicity of the solution,
e.g., medium is adjusted by increasing or decreasing the concentration of
potassium ions and NaCl.
In some aspects, the tonicity of a medium can be maintained by offsetting the
increase of one solute
with a decrease in a second solute. For example, increasing the concentration
of potassium ion in
a medium without changing the concentration of sodium ions can increase the
tonicity of the
medium. However, if the concentration of potassium ions is increased and the
concentration of
sodium ions is decreased, the tonicity of the original medium can be
maintained. As used herein,
the tonicity of a medium is defined by the sum of the potassium concentration
and the NaC1
concentration, multiplied by two. See, e.g., Table 2.

[0177] As used herein, the term "cytokine" refers to small,
secreted proteins released by
cells that have a specific effect on the interactions and communications
between cells. Non-limiting
examples of cytokines include interleukins (e.g., interleukin (IL)-1, IL-2, IL-
4, IL-7, IL-9, IL-13,
IL-15, IL-3, IL-5, IL-6, IL-11, IL-10, IL-20, IL-14, IL-16, IL-17, IL-21, IL-
23, and IL-29),
interferons (IFN; e.g., IFN-u, IFN-13, and IFN-y), tumor necrosis factor (TNF)
family members,
and transforming growth factor (TGF) family members. Some aspects of the
present disclosure are
directed to methods of culturing cells, e.g., T cells and/or NK cells, in a
medium comprising a
cytokine. Some aspects of the present disclosure are directed to methods of
culturing TILs in a
medium comprising a cytokine. Some aspects of the present disclosure are
directed to methods of
expanding TILs in a medium comprising a cytokine. In some aspects, the
cytokine is an interleukin.
In some aspects, the cytokine is selected from IL-2, IL-7, IL-15, IL-21, and a
combination thereof.
IL-2 (UniProtKB ¨ P60568) is produced by T cells in response to antigenic or
mitogenic
stimulation. IL-2 is known to stimulate T cell proliferation and other
activities crucial to regulation
of the immune response. IL-7 (UniProtKB ¨ P13232) is a hematopoietic growth
factor capable of
stimulating the proliferation of lymphoid progenitors. IL-7 is believed to
play a role in proliferation
during certain stages of B-cell maturation. IL-15 (UniProtKB ¨ P40933), like
IL-2, is a cytokine
that stimulates the proliferation of T-lymphocytes. IL-21 (UniProtKB ¨ Q91-
1BE4) is a cytokine
with immunoregulatory activity. IL-21 is thought to promote the transition
between innate and
adaptive immunity and to induce the production of IgG1 and IgG3 in B-cells. IL-
21 may also play
a role in proliferation and maturation of natural killer (NK) cells in synergy
with 1L-15, and IL-21
may regulate proliferation of mature B- and T-cells in response to activating
stimuli. In synergy
with IL-15 and IL-18, IL-15 also stimulates interferon gamma production in T-
cells and NK cells,
and IL-21 may also inhibit dendritic cell activation and maturation during a T-
cell-mediated
immune response.

[0178] As used herein, the term "higher than" means greater than
but not equal to. For
example, "higher than 5 mM" means any amount that is more than 5 mM, but which
does not
include 5 mM.
[0179] The term "preferentially," as used herein, refers to the
predominant outcome. For
example, if the methods disclosed herein preferentially promote expansion of
CD8-P TILs, it is to
be understood that the predominant product of the expansion is CD8+ TILs. The
term
"preferentially" does not necessarily mean that 100% of, e.g., the resulting
Tits are CD8', rather
the term suggests that CD8+ TILs are expanded to a greater extent than CD8-
Tits.
[0180] As used herein, "administering" refers to the physical
introduction of a therapeutic
agent or a composition comprising a therapeutic agent to a subject, using any
of the various
methods and delivery systems. The different routes of administration for a
therapeutic agent
described herein (e.g., a TIL cultured as described herein) include
intravenous, intraperitoneal,
intramuscular, subcutaneous, spinal or other parenteral routes of
administration, for example by
injection or infusion.

herein) can be administered via a non-parenteral route, such as a topical,
epidermal, or mucosal
route of administration, for example, intranasally, orally, vaginally,
rectally, sublingually, or
topically. Administering can also be performed, for example, once, a plurality
of times, and/or over
one or more extended periods.
[0183] As used herein, the term "antigen" refers to any natural
or synthetic immunogenic
substance, such as a protein, peptide, or hapten. As used herein, the term
"cognate antigen" refers
to an antigen which an immune cell (e.g., a TIL) recognizes and thereby,
induces the activation of
the immune cell (e.g., triggering intracellular signals that induce effector
functions, such as
cytokine production, and/or for proliferation of the cell).

Hodgkin's
lymphoma, and non-Hodgkin's lymphomas. Hematological malignancies are also
referred to as
"liquid tumors." Liquid tumor cancers include, but are not limited to,
leukemias, myelomas, and
lymphomas, as well as other hematological malignancies. TILs obtained from
liquid tumors may
also be referred to herein as marrow infiltrating lymphocytes (MILs).
[0186] A "solid tumor," as used herein, refers to an abnormal
mass of tissue. Solid tumors
may be benign or malignant. Nonlimiting examples of solid tumors include
sarcomas, carcinomas,
and lymphomas, such as cancers of the lung, breast, prostate, colon, rectum,
and bladder. The tissue
structure of a solid tumor includes interdependent tissue compartments
including the parenchyma
(cancer cells) and the supporting stromal cells in which the cancer cells are
dispersed, and which
may provide a supporting microenvironment.
[0187] As used herein, the term "immune response" refers to a
biological response within
a vertebrate against foreign agents, which response protects the organism
against these agents and
diseases caused by them. An immune response is mediated by the action of a
cell of the immune
system (e.g., a T lymphocyte (e.g., a TIL), B lymphocyte, natural killer (NK)
cell, macrophage,
eosinophil, mast cell, dendritic cell or neutrophil) and soluble
macromolecules produced by any of
these cells or the liver (including antibodies, cytokines, and complement)
that results in selective
targeting, binding to, damage to, destruction of, and/or elimination from the
vertebrate's body of
invading pathogens, cells or tissues infected with pathogens, cancerous or
other abnormal cells, or,
in cases of autoimmunity or pathological inflammation, normal human cells or
tissues. An immune
reaction includes, e.g., activation or inhibition of a T cell, e.g., an
effector T cell or a Th cell, such
as a CD4+ or CD8 '1Th, or the inhibition of a Treg cell. As used herein, the
terms "T cell" and "T
lymphocytes" are interchangeable and refer to any lymphocytes produced or
processed by the
thymus gland. In some aspects, a TIL is a CDS+ TIL. In some aspects, a TIL is
a CD4+ TIL.

"subject in need thereof'
includes subjects, such as mammalian subjects, that would benefit, e.g., from
administration of
immune cells, e.g., Tits, cultured as described herein to control tumor
growth.
[0190] The term "therapeutically effective amount" or
"therapeutically effective dosage"
refers to an amount of an agent (e.g., a TIL cultured as described herein)
that provides the desired
biological, therapeutic, and/or prophylactic result That result can be
reduction, amelioration,
palliation, lessening, delaying, and/or alleviation of one or more of the
signs, symptoms, or causes
of a disease, or any other desired alteration of a biological system. In
reference to solid tumors, an
effective amount comprises an amount sufficient to cause a tumor to shrink
and/or to decrease the
growth rate of the tumor (such as to suppress tumor growth) or to prevent or
delay other unwanted
cell proliferation. In some aspects, an effective amount is an amount
sufficient to delay tumor
development. In some aspects, an effective amount is an amount sufficient to
prevent or delay
tumor recurrence. An effective amount can be administered in one or more
administrations.
[0191] The effective amount of the composition (e.g., cells
cultured as described herein)
can, for example, (i) reduce the number of cancer cells; (ii) reduce tumor
size; (iii) inhibit, delay,
slow to some extent and can stop cancer cell infiltration into peripheral
organs; (iv) inhibit (i.e.,
slow to some extent and can stop tumor metastasis); (v) inhibit tumor growth;
(vi) prevent or delay
occurrence and/or recurrence of tumor; and/or (vii) relieve to some extent one
or more of the
symptoms associated with the cancer.
[0192] In some aspects, a "therapeutically effective amount" is
the amount of a
composition disclosed herein (e.g., T cells cultured as described herein),
which is clinically proven
to effect a significant decrease in cancer or slowing of progression
(regression) of cancer, such as
an advanced solid tumor. The ability of a therapeutic agent of the present
disclosure (e.g., T cells
cultured as described herein) to promote disease regression can be evaluated
using a variety of
methods known to the skilled practitioner, such as in human subjects during
clinical trials, in
animal model systems predictive of efficacy in humans, or by assaying the
activity of the agent in
Iii vitro assays.

refers to a heterodimer
composed of 2 different transmembrane polypeptide chains: an a chain and a 1
chain, each
consisting of a constant region, which anchors the chain inside the T-cell
surface membrane, and
a variable region, which recognizes and binds to the antigen presented by
MFICs. The TCR
complex is associated with 6 polypeptides forming 2 heterodimers, CD3yE and
CD3oE, and 1
homodimer CD3 which together forms the CD3 complex. T-cell receptor-engineered
T-cell
therapy utilizes the modification of T cells that retain these complexes to

different ratios of TIL to
PBMCs can be used compared to the research scale MR1\4 process. For instance,
in some aspects,
the ratio of TIL to PBMCs for a large scale MR1VI process is less that the
corresponding ratio for
the research scale MRM process. In some aspects, culture and/or expansion
times can be shorter
for large scale TIL than for research scale TIL. In some aspects, a dynamic
REP step is included
in the large scale process.
[0200] Various aspects described herein are described in further

11. Methods of the Disclosure
[0201] The present disclosure is directed to methods of
culturing immune cells, e.g., TILs,
ex vivo or in vitro. In some aspects, the methods of the present disclosure
comprise culturing or
placing immune cells, e.g., TILs, in a culture condition, wherein the culture
(e.g., certain ion
concentrations, tonicity of the medium, cytokines, and or any combination
thereof) is capable of
enhancing the expansion of CDS+ TILs. In some aspects, the culture (e.g.,
certain ion
concentrations, tonicity of the medium, cytokines, and or any combination
thereof) is capable of
reducing, limiting, or preventing the differentiation of the immune cells,
e.g., the TILs (e.g., CD8+
TILs and/or CD4 TILs), thereby affecting or improving their use in a cell
therapy. In some aspects,
the present disclosure comprises culturing of TILs in a metabolic
reprogramming media that is
high in potassium concentration. Increased potassium was surprisingly found to
correlate with
increased expansion of CD8+ TILs that have increased expression of stem-like
markers and
increased clonal diversity, while maintaining tumor-reactivity (e.g., tumor
specificity), as
compared to conventional methods using lower potassium levels, e.g., less than
about 40 mM
potassium ion, e.g., 5 mM potassium ion. Further, though exceedingly high
concentrations of
potassium (e.g.,> 80 mM, >90 mM, or > 100 mM) reduced TIL expansion, the
methods described
herein yielded therapeutically effective numbers of TILs following culture
conditions, e.g.,
durations, consistent with conventional methods.
[0202] The use of immunotherapy strategies has demonstrated
considerable clinical
efficacy in the treatment of certain types of advanced cancer. Immune
checkpoint blockade (ICB)
can result in objective and sometimes durable responses in patients with
metastatic melanoma.
Certain cohorts of colon cancer, lung cancer patients and small proportions of
patients with
additional malignancies can also benefit from ICB. Chimeric antigen receptor
(CAR) T cell therapy
has mediated dramatic clinical responses in patients with blood cell
malignancies, most notably B
CA 03234821 2024-4- 11

WO 2023/077034
PCT/US2022/078827
-49 -
cell-lineage tumors that can be targeted with CD19 or B cell maturation
antigen (BCMA) CARs.
Treatment with T cells transduced with T cell receptors (TCRs) that recognize
shared, non-mutated
tumor antigens such as NY-ESO-1 can also mediate clinical responses in
patients who express
TCR matched human leukocyte antigens (HLAs). However, in spite of these
notable successes, the
vast majority of patients with advanced cancers still do not benefit from
immunotherapy treatments
and will eventually succumb to their illness.
[0203] TIL therapy has also shown a potential in mediating
clinical responses in patients
with advanced cancer. Emerging evidence has demonstrated that TILs are a
heterogenous
population composed of both tumor-reactive and non-specific bystander cells.
This heterogenous
population of TILs causes difficulty and unwanted effects in the TIL therapy
and/or dilution of the
efficacy of the TIL therapy as the non-specific bystander cells in the
heterogenous population are
not preferred. Bystander cells are nonspecific T cells, which can dilute the
diversity of reactive
TILs. Bystander cells include TILs that recognize epitopes that are not tumor
related. In addition,
the efficacy of TIL therapy has demonstrated diverse responses in patients
with melanoma,
advanced cervical, lung, breast, and/or gastrointestinal cancers.
[0204] In some aspects, the present disclosure provides methods
of reducing the
heterogeneity of TIL population ex vivo or in vitro for an in vivo therapy. In
some aspects, the
methods disclosed herein enrich for a particular type of a TIL population,
e.g., CD8+ TILs and/or
tumor-reactive CD8+ TILs. In some aspects the methods disclosed herein enrich
for stem-like T
cell populations, e.g., stem-like tumor-reactive TILs and/or stem-like tumor-
reactive CD8+ TILs.
[0205] Not being bound by any theory, the present disclosure
sets forth a method of

Artificial antigen presenting cells (aAPCs) such as genetically engineered
human K562 aAPCs can
be used for rapid expansion of TILs. In some aspects, the aAPC is generated by
transducing K562
cells with a polycistronic lentiviral vector comprising genes encoding CD70,
CD80, CD86, 41BB
ligand, and 0X40 ligand. K562 cells do not express HLA-A, I-11,A-B, or 1-11A-
DR molecules,
which makes them a powerful tool for T cell expansion when transduced with the
above mentioned
co-stimulatory ligands (See, e.g., Suhoski et al., Molecular therapy, 2007).
In some aspects,
secondary TIL expansion and/or third TIL expansion comprises co-culturing the

[0364] In some aspects, the MRM, e.g., secondary TIL expansion
media and/or third (or
final) TIL expansion media, comprise and/or are supplemented with a CD27
ligand (CD27L).
CD27 ligand (CD70) is capable of binding to its receptor, and then upon
binding, the receptor is
capable of generating and long-term maintenance of T cell immunity. CD27 is a
member of the
TNF-receptor superfamily. CD27, a transmembrane homodimeric
phosphoglycoprotein of 120
lcDa, also appears to have a costimulatory role. CD27L, CD70, is a
transmembrane glycoprotein
expressed on T and B cells in response to antigen stimulation; it is thus
considered a marker of the
early stages of activation. In vitro, the interaction of CD27 on a T cell and
CD70 on a B cell
enhances T cell activation in terms of proliferation but only relatively low
amounts of IL-2 are
secreted. Studies of knockout mice have shown that CD27 plays a minor part in
naive T cell
activation but is crucial for the generation of T cell memory.

reaches at least about 100x109 cells.
[0428] In some aspects, the final expansion is continued until

until the cell yield in
the final TIL media for at least about 21 days.
[0429] In some aspects, the secondary expansion and the final
expansion are merged into
a single secondary expansion. In some aspects, the single secondary expansion
comprises all
aspects of the secondary expansion and the final expansion. In some aspects,
the single secondary
expansion takes place in a closed system (e.g., a GREX closed system), wherein
the closed system
is not opened for the duration of the single secondary expansion. In some
aspects, the cells are split
during the single secondary expansion once the cells reach high confluence.
[0430] In some aspects, the full duration of the expansion
process (e.g., (i) the initial
expansion process, the secondary expansion process, and the final expansion
process; or (ii) the
initial expansion process and the single secondary expansion process) is 22
days or less. Generation
of young TILs using shorter expansion processes confers various benefits on
the resulting T1L
composition. As such, the culture conditions and methods disclosed herein
confer additional
CA 03234821 2024-4- 11

WO 2023/077034

benefits, e.g., increased stem-like characteristics, expanded clonal
diversity, improved cytolytic
activity, and/or increased CD8+ cell expansion, on those already identified
for young TILs.
11.1.2. b. Secondary Expansion by Static-REP and Dynamic-REP
[0431] In some aspects, secondary expansion comprises a static-
REP step followed by a
dynamic-REP step. As used herein, "static-REP" refers to an expansion step
wherein TILs
harvested from pre-REP or an initial expansion, e.g., as disclosed herein, are
further expanded in
a medim comprising greater than 4 mM potassium ion, e.g., an MRM disclosed
herein, a CD3
agonist (e.g., OKT3), and antigen presenting cells (e.g., irradiated
allogeneic PBMCs). In some
aspects, the agitation of the culture is not applied during static-REP.
"Dynamic-REP," as used
herein, refers to an expansion step wherein TILs from the static-REP are
further expanded in a
medium comprising greater than 4 mM potassium ion until a therapeutic number
of TILs is
reached, wherein the culture occurs under agitation. In some aspects, the
method comprises
expanding a population of TILs obtained from a human subject comprising (a)
culturing the TILs
in a medium comprising greater than 4 mM potassium ion, a CD3 agonist, and
antigen-presenting
cells (a "static-REP step"); and (b) adding to the TILs from the static-REP
step a medium
comprising greater than 4 mM potassium ion, wherein agitation is applied to
the culture (a
"dynamic-REP step"). In some aspects, no CD3 agonist is added during the
dynamid-REP. In some
aspects, no antigen-presenting cells are added during the dynamic-REP step. In
some aspects, no
CD3 agonist and no antigen-presenting cells are added during the dynamic-REP
step.
[0432] In some aspects, the TILs obtained during static-REP are
added directly to the
dynamic-REP. In some aspects, the TILs are not split between the static-REP
and the dynamic-
REP. In some aspects, the TILs are cryopreserved following the static-REP and
prior to the
dynamic-REP.
[0433] In some aspects, static-REP medium comprising the
expanded TILs is applied
directly to the dynamic-REP As such, in some aspects, day 0 of dynamic-REP
includes TILs
present in a medium that comprises a CD3 agonist and antigen-presenting cells,
which was carried
over from the static-REP to the dynamic-REP with the TILs. However, in some
aspects, no
additional CD3 agonist or antigen-presenting cells are added during the
dynamic-REP step. Over
time, an increasing concentration of CD3 agonist that had carried over from
the static-REP is
degraded or otherwise lost, resulting in a decreasing concentration of CD3
agonist during the
dynamic-REP step.

WO 2023/077034
PCT/US2022/078827

[0434] Further, the dynamic-REP step comprises applying
agitation to the culture. In some
aspects, the agitation comprises rocking the culture. Traditional REP culture
includes culturing
TILs in the presences of antigen-presenting cells, such as irradiated PBMCs.
However, PBMCs
have reduced viability in culture when subjected to agitation, such as
rocking. As such, traditional
REP culture is performed without rocking or otherwise agitating the cells.
However, the present
disclosure surprisingly found that the methods disclosed herein, which include
a dynamic-REP
step that comprises agitation, increased the yield and improved the properties
of the resulting TIL
product. This would not have been expected, as the dynamic-REP step disclosed
herein allows for
gradually reducing the presense of both the CD3 agonist and the antigen-
presenting cells during
TIL expansion, two factors which are hallmarks of REP methods.
[0435] In some aspects, the dynamic-REP step comprises
perfusion. As used herein,
"perfusion" refers to a method of culturing cells, e.g., TILs, wherein a
portion of the culture
medium is constantly replaced with fresh medium without removing the cultured
cells, e.g., TILs.
The rate of perfusion can be carefully controlled. In some aspects, the
perfusion comprises
continuous media exchange at a rate of about 10%, about 15%, about 20%, about
25%, about 30%,
about 35%, about 40%, about 45%, about 50%, about 55%, or about 60% of the
working volume
of the culture vessel every 24 hours. In some aspects, the perfusion comprises
continuous media
exchange at a rate of about 5% of the working volume of the culture vessel
every 24 hours.In some
aspects, the perfusion comprises continuous media exchange at a rate of about
10% of the working
volume of the culture vessel every 24 hours.In some aspects, the perfusion
comprises continuous
media exchange at a rate of about 15% of the working volume of the culture
vessel every 24
hours.In some aspects, the perfusion comprises continuous media exchange at a
rate of about 20%
of the working volume of the culture vessel every 24 hours.In some aspects,
the perfusion
comprises continuous media exchange at a rate of about 25% of the working
volume of the culture
vessel every 24 hours. In some aspects, the perfusion comprises continuous
media exchange at a
rate of about 30% of the working volume of the culture vessel every 24 hours.
In some aspects, the
perfusion comprises continuous media exchange at a rate of about 35% of the
working volume of
the culture vessel every 24 hours. In some aspects, the perfusion comprises
continuous media
exchange at a rate of about 40% of the working volume of the culture vessel
every 24 hours. In
some aspects, the perfusion comprises continuous media exchange at a rate of
about 45% of the
working volume of the culture vessel every 24 hours. In some aspects, the
perfusion comprises
continuous media exchange at a rate of about 50% of the working volume of the
culture vessel
every 24 hours. In some aspects, the perfusion comprises continuous media
exchange at a rate of

about 55% of the working volume of the culture vessel every 24 hours. In some
aspects, the
perfusion comprises continuous media exchange at a rate of about 60% of the
working volume of
the culture vessel every 24 hours.
[0436] In some aspects, the perfusion rate is constant for the
entirety of the dynamic-REP
step. In some aspects, the perfusion rate is varied during the dynamic-REP
step. In some aspects,
the perfusion comprises continuous media exchange at a rate of about 25% of
the working volume
of the culture vessel every 24 hours for the first 48 hours of the dynamic-REP
culture, and wherein
the perfusion comprises continuous media exchange at a rate of about 50% of
the working volume
of the culture vessel every 24 hours for the remainder of the dynamic-REP
culture.
[0437] In some aspects, the volume of the culture medium is held
constant for the entirety
of the dynamic-REP step. In some aspects, the volume of the culture medium is
varied during the
dynamic-REP step. In some aspects, the volume of the culture medium is
increased during the
dynamic-REP step. In some aspects, the perfusion comprises adding more medium
to the culture
than is removed. In some aspects, the volume of the culture medium is
increased from hour 0 to
hour 48 of the dynamic-REP step. In some aspects, the volume of the culture
medium is increased
from hour 0 to hour 48 of the dynamic-REP step, and the volume of the culture
is maintained, i.e.,
neither increased in volume by more than 10% nor decreased in volume by more
than 10%, from
hour 48 until the completion of the dynamic-REP step. In some aspects, the
volume of the medium
is increased by at least about 10%, at least about 15%, at least about 20%, at
least about 25%, at
least about 30%, at least about 35%, at least about 40%, at least about 45%,
or at least about 50%
every 24 hours for the first 48 hours. In some aspects, the volume of the
medium is increased by

characteristics of a cell (e.g., TILs) can be assessed using tran seri ptome
analysis by comparing the
upregulation and/or downregulation of different sets of genes associated with
stem-like cells (see,
e.g., Table 3, Panel 1-4), exhaustion (see, e.g., Table 3, Panel 5-10), and
metabolic fitness (see,
e.g., Table 3, Panel 11-19).
[0495] In some aspects, the terminally exhausted T cells are
characterized using a TTE-
associated gene set described in Oliveira et al., Nature 596: 119-125 (2021).

[0496] In some aspects, the TIL is an engineered TIL. As used
herein, an "engineered" TIL
refers to a TIL that has been manipulated in a way, e.g., according to the
methods discosed herein,
that confers on the TIL one or more physical and/or functional properties that
are not characteristic
of a naturally occurring TIL. For example, in some aspects, an engineered TIL
can be generated
by modifying a TIL to express one or more proteins heterologous to the cell
(e.g., chimeric antigen
receptor or T cell receptor) so that the engineered TIL is not naturally
occurring. In some aspects,
an engineered TIL can be generated by culutirng a TIL in a particular way,
e.g., culturing in
hyperkalemic medium, wherein the resulting engineered TIL has one or more
physical and/or
functional properties that are not shown in naturally occurring cells.

[0549] As described and demonstrated herein, in some aspects,
the culturing processes
described herein (e.g., expanding and culturing cells in MRM) can improve one
or more properties
of TILs of a tumor that is refractory to one or more immune checkpoint
inhibitors. For instance, in
some aspects, culturing such TILs using the MRM processes described herein can
increase the
sternness of the TILs (i.e., the TILs are more stem-like as compared to the
TILs prior to the
culturing and/or as compared to corresponding TILs that were cultured using a
non-MRM process).
In some aspects, after culturing with the MRM process, the sternness of the
TILs from the
refractory tumor is increased by at least about 10%, at least about 20%, at
least about 30%, at least
about 40%, at least about 50%, at least about 60%, at least about 70%, at
least about 80%, at least
about 90%, or at least about 100% as compared to reference TILs (e.g., the
TILs prior to the
culturing with the MR1\4 process and/or corresponding TILs that were cultured
using a non-MRM

fold, at least about 4-fold,
at least about 5-fold, at least about 6-fold, at least about 7-fold, at least
about 8-fold, at least about
9-fold, at least about 10-fold, at least about 15-fold, at least about 20-
fold, at least about 25-fold,
at least about 30-fold, at least about 40-fold, or at least about 50-fold as
compared to the reference
TILs. Accordingly, as is apparent from the present disclosure, in some
aspects, the MRM process
described herein can be used to increase the sternness of TILs from tumors
that were previously
treated with one or more immune checkpoint inhibitors.
[0550] Exemplary methods of measuring the sternness of TILs are
provided elsewhere in
the present disclosure. For instance, in some aspects, sternness can be
measured by determining
the expression of one or more stem-like markers, e.g., CD45RA+, CD62L+, CCR7+,
CD27+,
CD28+, BACH2+, LEF1+, TCF7+, CD39-, CD69-, or a combination thereof. In some
aspects, the
sternness of the TILs can be measured by measuring the expression of CD39 and
CD69 on the
TILs. As further described elsewhere in the present disclosure, stem-like
cells are CD39- and
CD69-. Accordingly, in some aspects, after culturing TILs from a tumor that is
refractory to one
or more immune checkpoint inhibitors with the MRI\4 process, at least about
15%, at least about
20%, at least about 25%, at least about 30%, at least about 35%, at least
about 40%, at least about
45%, at least about 50%, at least about 55%, at least about 60%, at least
about 65%, or at least
about 70% of the expanded TILs are CD39- and CD69-.

[0554] Cell culture and Transduction: Healthy donor
cryopreserved human CD4 and
CD8 cells were activated with TransAct (Miltenyi) in T cell conditioned media-
TCM, basal media,
or hypotonic conditioning medium. After 24 hours of activation in the TCM,
basal media, or
hypotonic conditioning medium, T cells were transduced with lentiviral
particles to introduce
chimeric antigen receptor (anti-CD19 CAR) in Grex plates (Wilson Wolf). The
following day after
transduction, T cells were supplemented with fresh media to dilute the
TransAct and end T-cell
activation. Depending on the cell growth and density, T cells were fed with
warm 2X cytokine
media by aspirating half of the media in the Grex plate. On day 7, cells were
harvested, counted
and analyzed for the expression of sternness markers by flow cytometry.
[0555] Intracellular Cytokine assays: On day 7, T cells were
washed and placed in
control media and subjected to a 5 hour re-stimulation with phorbol myrystate
acetate (PMA) and
ionomycin in the presence of brefeldin A to measure intracellular cytokines,
IL-2, IFNy, and
TNFa. T cells were stained with surface antibody staining in FACS buffer
containing fixable live/
dead solution. Cells were stained with respective antibodies for intracellular
cytokines following
fixation and permeabilization. Quantification of intracellular cytokine
expression was assessed
using flow cytometry.
[0556] Sternness phenotype CAR expression measurement via flow
cytometry: On day
7, live T cells from the respective treatments were assessed via flow
cytometry. Cells were first
washed with cell staining buffer and stained with anti-CCR7 for 15 minutes at
37 C. Following
this, a 2x master mix of the antibodies against several other antigens (as
detailed below) was added
to cells and incubated for 20 minutes at 4 C. Cells were washed with cell
staining buffer and
permeabilized with the foxp3 staining kit (ebioscience) as per manufacturers'
protocol. After
fixing, the cells were stained for TCF7 for twenty minutes at 4 C following
which, cells were
analyzed by flow cytometry on aurora (cytek). The following are the list of
antibodies used for
assessing the sternness markers: CD8 (BD-4563795), CD4 (BD-4 612936), CD27 (BD-
4612829),
CD3 (Thermo-4 612893), CD28 (Biolegend- 4302936), CD62L, CAR-EGFR (Thermo-

Example 2. Methods of Preparing Media and Culturing TILs
[0557] Control Media: Commercially available T cell media (e.g.,
CT STm
OPTIMIZERTm, INIMUNOCULTTm or TEXMACSTm).
[0558] Metabolic reprogramming media ("MRM"): The inorganic salt
ion
concentrations of T cell media were adjusted using NaCl free T cell media. The
final concentrations
of MRM were the following: NaC1 (40-80 mM), KC1 (40-90 mM), Calcium (0.5-2.8
mM), Glucose
(10-24 mM) and osmolality (-250-340 mOsmol).
[0559] TIL media preparation used for initial culture and
secondary and final TIL
expansions: Either Control media or MRM was supplemented with 2.5% serum
supplement
(CTSTm Immune Cell SR, Thermo Fisher), 2 mM L-glutamine (Gibco), 2 mM L-
glutamax (Gibco),
MEM Non-Essential Amino Acids Solution (Gibco), Pen-strep (Gibco), 2014/m1
FUNGE\FTM
(InvivoGen), Sodium pyruvate (Gibco), and 1mM of O-Acetyl-L-carnitine
hydrochloride (Sigma).
[0560] Initial TIL Culture: FIG 1 is a schematic depicting
generally certain aspects of the
methods of culturing TILs described herein. Multiple tumors surgically
resected from various
tumor types (colon, lung, hepatocellular carcinoma, renal, pancreas, breast,
melanoma, and
prostate) with an average size of 1-10mm3 were seeded in 24-well plates in 2m1
of either control
media or MRM as described above, both supplemented with IL-2 (300ng/mL) and IL-
21
(30ng/m1). Tumor fragments were cultured in a heat jacketed incubator at 37 C
incubator with 5%
CO2 until colony formation was visible Fresh media (control or MRM)
supplemented with IL-2
(300ng/mL) and IL-21 (30ng/m1) were replenished every 3 days depending on the
growth of the
cells. This method resulted in a yield of about 2x106-10x106 cells per
fragment at the end of the
initial culture. A subset of cells for analysis were passed through a 40p.m
strainer and pheonotyped
with multi color flow cytometry using various biomarkers including CD62L,
CD27, CD28,
CD45RO, CD39, TI1V13, CD127, PD1, CD103, CD45RA, and TCF7.
[0561] Secondary TIL Expansion: When cell yield from the initial
culture reached about
2x106-10x106 cells per cultured fragment (usually at about day 14 to day 19),
the TILs cultured in
either control media or MRM, both supplemented with IL-2 (73.6ng/m1), IL-
21(10ng/m1), and IL-
15 (0.4ng/m1), were stimulated by adding 1:100 T cell TRANSACT' (Miltenyi
Biotec), 5 jig/ml
recombinant human CD27 ligand (R&D systems), and 1 n.g/m1 recombinant human 4-
1BB
ligand/TNFSF9 (R&D systems). Cells were maintained in culture until about
5x107 to 20x107 cells
were obtained (about 7 to 11 days post-stimulation). At the end of the
secondary expansion period,
TILs were analyzed with multicolor flow cytometry using various biomarkers
including, CD62L,

- 202 -
CD27, CD28, CD45RO, CD39, TIM3, CD127, PD1, CD103, CD45RA and TCF7. Only live
and
CD3+ cells were analyzed.
[0562] Final TIL Expansion: When the cultures reached a yield of
about 5x107 to 20x107
cells, the TILs cultured in either control media or MRM were transferred to
fresh control media
supplemented with IL-2 (73.6ng/m1), IL-21(10ng/m1), and 1L-15 (0.4ng/m1). TILs
were stimulated
for a second time with 1:100 TRANSACTTm (Mil tenyi Biotec), 5ps/m1 recombinant
human CD27
ligand (R&D systems), and 1 ,g/m1 recombinant human 4-1BB ligand/TNF SF9 (R&D
systems).
The cells were cultured in static GREX or stirred tank until a yield of about
10x109-100x109 cells
per fragment was achieved (about 14 days) and analyzed with multi color flow
cytometry for
various bi markers, including CD62L, CD27, CD28, CD45RO, CD39, TIM3, CD 127,
PD I ,
CD103, CD45RA, and TCF7. To check for polyfunctionality of the cells, the
resultant TILs were
stimulated with PMA/ionomycin (1:500) for 4 hours and intracellular staining
was performed using
the following markers: CD4, CDR, CD27, IL2, IFNy, TNFa and TCF7. Only live and
CD3+ cells
were analyzed.
Example 3. MRM results in expansion of CD8+, tumor-reactive, less
differentiated TILs
[0563] TILs were grown as described in Example 1 (FIG. 1). After
the initial T1L culture
(i.e., 14 days), multiparameter flow cytometry was performed to quantify the
percentages of CD4+
and CD8+ TILs present in the cell culture. Cells cultured in MRM had
significantly enriched CD8+
TILs by ¨20-80% as compared to the cells cultured in control media (FIGs. 2A-
2C and data not
shown). Although CD4 TlLs are capable of eradicating solid tumors, superior
cytolytic activity
towards tumors is primarily mediated by CD8+ TILs. Tumor cells predominantly
express MT1C
class I associated tumor antigens, which are recognized by CD8+ TILs. Thus,
having a greater
proportion of CD8+ TILs in the TIL therapy infusion product is therapeutically
beneficial. Use of
MRM to culture TILs unexpectedly enriched CD8+ TILs as compared to TILs
cultured in control
media (FIG. 2C).
[0564] Tits obtained at the end of the initial culture in MRM
(about day 14) also
demonstrated consistent expression of several cell surface markers of tumor-
reactive TTLs (e.g.,
CD39, CD103, CD226, and/or PD1). Initial culturing in MRM produced TILs with
enhanced
expression of CD39 and PD1 (greater than 20%) as compared to TILs cultured in
control media
(FIGs. 2A-2B). Previously used methods show that PD1 expression is completely
lost in the PD1
subsets during initial TIE culture, indicating undesirable loss of tumor-
reactive TILs (see, e.g.,
Poschke et al, Oncoimmunology 5(12):e1240859 (2016); and Gros et al, JCI
124(5):2246-59

(2014)). We obseverved that maintenace of PD1 expression after T cell
stimulation was dependent
on donor (data not shown). Similar results were obtained for expression of
other markers of tumor
reactivity including CD39 and CD103 (see FIGs. 2A-2B and 5A-5B, and data not
shown).
However, clonal repertoire observed at day 14 is maintained throughout entire
TIL process (data
not shown).
[0565] We also observed co-expression of PD1 (indicative of a
tumor-reactive metabolic
state) and CD27, in both CD4 and CD8- TILs cultured in MRM (FIGs. 3A-3E). CD27
expression,
which is constitutively expressed on naïve and memory committed T-cells, is
indicative of a stem-
like phenotype in T cells. Previous reports indicate that CD27 expression is
reduced in CD8+ T
cells during cell expansion following T cell stimulation (see, e.g., Tran et
al., J Immunotherapy
31(8):742-51 (2008); and Rosenberg et al., Clinical Cancer Research
17(13):4550-557 (2011),
Huang et al, J. Immunology 176(12).7726-35 (2006)). In contrast, TILs cultured
in MRM,
disclosed herein, have preserved CD27 expression throughout the culturing
process, allowing for
selective expansion of stem-like tumor-reactive clones. As expected, not all
CD27 + cells at day 14
co-expressed PD1, indicating that not all stem-like cells displayed a tumor-
reactive metabolic state.
[0566] Anti-tumor function and survival of TILs are dependent on
the consolidated signals
received by the TCR, cytokine, and costimulatory receptors. Inadequate
exposure of any of these
signals will result in anergy and atrophy of the Tits. Previously used methods
of culturing and
expanding TILs result in loss of CD27 expression in the TILs. However, TILs
that maintain CD27
expression in an infusion product, e.g., in minimally expanded TILs, have been
shown to be
associated with tumor regression following adoptive T cell therapy (see, e.g.,
Tran et al., J.
Immunotherapy 31(8)742-51 (2008); and Rosenberg et al., Clinical Cancer
Research
17(13):4550-557 (2011)). In addition, elevated expression of costimulatory
receptors, e.g, CD27
and CD28, is associated with in vivo therapeutic efficacy (Tran et al., J.
Immunotherapy 31(8):742-
51(2008), Geltink et al., Cell 171, 385-397 (2017)). Expression of these
costimulatory receptors
has also been associated with stemness and longer telomere lengths that
correlated with young TIL
cultures. In contrast to previously used methods, e.g., control media, the use
of MRM described
herein enriched TILs with CD27 and CD28 expression to about 20% to about 80%
of the total
number of TILs across several tumor types (FIG. 4 and data not shown).
Enrichment of CD27 and
CD28 was not unique to the CD8 T cell subset but was also observed in the
CD4' subset (data not
shown).
[0567] Expression of CD27 and CD62L is correlated with less
differentiated T cells and is
associated with efficient trafficking of the T cells to tumor tissues and
lymph nodes. Expression of

WO 2023/077034
PCT/US2022/078827
- 204 -
CD27, CD28, and CD62L is also linked to longer telomere length, which is
indirectly linked to the
age of the TIL and in vivo therapeutic efficacy (see, e.g., Tran et al., J.
Inentunotherapy 31(8):742-
511 (2008); and Rosenberg et al., Clinical Cancer Research 17(13):4550-557
(2011)). However,
TILs cultured in MR1\4, as disclosed herein, maintained both CD27 and CD62L
expression
throughout the process, similar to that of minimally cultured TILs. We
observed a ¨50% increase
in CD27 and CD62L expression in TILs cultured in MRI\4 as compared to those
cultured in control
media (data not shown).
[0568] Tumor-reactive clones that mediate tumor regression post
immune checkpoint
blockade are believed to be derived from the CD8+ T cells that expressed PD1
and transcription
factor TCF-7 (Im et al., Nature 537:417-21 (2016); and Feldman et at., Cell
175(4):998-1013
(2018)). TILs cultured in MRM disclosed herein displayed enrichment of tumor-
reactive TIL
biomarkers (PD1 and CD103) with a concurrent 4-fold to 50-fold higher level of
TCF7 expression
(FIGs. 5A-5C, 6D, 6H, 10). Expression of TCF7 is indicative of more stem-like
cells. Despite the
expression of PD1, these cells retained proliferative capacity and maintained
less differentiated
cells upon further stimulation (FIGs. 6A-6H).
Example 4: MR1V1 preserves tumor reactivity of TILs
[0569] Tumors are heterogenous in nature and often contain
common mutations in genes
such as KRAS, P53, and BRAF (public neoantigens). The methods using MRM as
disclosed herein
enriched for TILs that recognize such neoantigens.
[0570] Tumor resections were obtained from a patient with
pancreatic adenocarcinoma, a
cancer that predominantly has tumor cells with KRASG12V, KRAsG12C, and
KRASG12D mutations.
HPLC-purified 9mer, 1 Omer, and 25mer peptides of the above-mentioned KRAS hot
spot
mutations were purified and used to pulse immature dendritic cells (DCs)
generated from patient-
matched peripheral blood monocytes. These peptide pool-pulsed DCs were co-
cultured with TILs
obtained from the same pancreatic adenocarcinoma patient and cultured
according to the methods
described in the Examples above. Culture of the TILs in MRM resulted in ¨30%
more CDS+ T
cells with significant co-expression of CD27, CD28, PD1, and TCF-7 (FIGs. 7A-
7H). These results
indicate that MRI\4 disclosed herein preserves tumor-reactive TCR clones that
recognize public
antigens.
[0571] As expected, TILs pulsed with wild type KRAS peptides did
not result in specific
expansion of KRAS-specific TILs. However, we consistently observed increased
expression of
CD27, CD28, PD1, and TCF7 expression by TILs cultured in MR1\4. These results
indicate that
CA 03234821 2024-4- 11

WO 2023/077034
PCT/US2022/078827
- 205 -
culturing cells in MRM preserves the growth and proliferation of TILs that
recognize rare public
neoantigens (FIGs. 8A-8H).
[0572] Preferential enrichment of CDS+ TILs and markers
associated with tumor reactivity
(CD39 and PD I) were maintained during this expansion process (FIGs. 9A-9B).
These results
show that MRM further enhances PD1 expression in tumor-reactive TILs even
after initial culture.
In addition, TILs cultured in MRM according to the methods disclosed herein
exhibited a greater
than 50-fold increase in TCF7 expression as measured by qPCR (FIG. 10). These
data are
consistent with the role of TCF7, which is a master transcriptional regulator
required for self-
renewal and proliferative burst of the Tits post re-stimulation.
[0573] Expression of CD103 in TILs is reported to be correlated
with TIL infiltration in
tumors with high mutation antigen burden. In addition to CD39 and PD1
expression, our data
demonstrated that expansion of TILs in MRM increased the number of PD1 CD39
CD103+ cells
(FIGs. 11A-11L) while also increasing expression of sternness-associated
genes. Therefore, culture
of TILs in MRM may be sufficient to increase the number of cells with both
tumor-reactivity and
higher proportion of stem-like cells in the resulting expanded cell products.
[0574] The data presented herein demonstrate that expansion of
TILs in MRM generates
cell populations with not only increased sternness, but also increased
expression of several cell
surface markers associated with tumor reactivity. The methods described herein
using MRM
produce TILs that have characteristics and properties of an improved
therapeutic product.
Example 5. Methods of Treatment
[0575] Tits that are used for infusion are derived from a
pateint's tumor excised from
primary or metastatic tuomors or lymph nodes. TIL cultures are initiated by
plating the small tumor
fragments (-1-10 mm3) in 24 well plates containing MRM as described above in
Example 1. These
fragments are grown until about 2 x 106 to about 10 x 106 cells / tumor
fragment are obtained
(typically about 2-3 weeks). The resuting cells from all the fragments are
pooled and plated at a
density of 2 x 106/well for T cell stimulation, e.g., by adding TRANSACTTm,
and optionally CD27
agonist, 41BB agonist, and/or OX-40 agonist. Cells are maintained in culture
until about 5 x 10'
to about 20 x 107 cells are obtained. These cells are further stimulated,
e.g., using TRANSACTTAI
and optionally CD27 agonist, 41BB agonist, and/or OX-40 agonist to achieve
about 1000-2000
fold increase in the number of cells (-A -150 x 109-Tits) for the infusion
product.
[0576] Prior to administration of the TIL infusion product,
patients are administered a
lymphodepletion treatment, e.g., comprising cyclophosphamide and fludarabine.
In addition to TIL
CA 03234821 2024-4- 11

WO 2023/077034
PCT/US2022/078827
- 206 -
infusion, patients may also receive an anti-PD1 checkpoint inhibitor (e.g.,
pembrolizumab or
nivolumab) after infusion of TILs cutltured as disclosed herein.
Example 6. Analysis of Clonal Diversity
[0577] To assess the clonal diversity of TILs cultured in MRM,
according to the methods
disclosed above, tumor fragments and TILs obtained from the tumor fragments
were cultured in
either control media or metabolic reprogramming media (MRM). Total genomic DNA
was isolated
from tumor and TIL samples using DNeasy Blood and Tissue Kit (QIAGEN) and
sequenced using
Immuno-seq for TCRf3 and CDR3 regions (Adaptive Biotechnologies, Seattle, WA).
[0578] The diversity metrics of the samples were assessed by
Simpsons clonality
where pi is the proportional abundance of clone i in a given sample. Simpsons
clonality and
productive rearrangements were examined in tumor fragments ("tumor"), TILs
cultured in control
media ("control"), and TILs cultured in MRM ("MRM") (FIG. 12). TILs cultured
in MRM (post-
expansion) displayed Simpsons clonality of approximately 0.04, which indicates
high clonal
diversity, similar to what is seen in the tumor fragments (FIG. 12).
Maintenance of TCR13 diversity
represent preservation of TEL clonotypes that infilatrated the tumors and are
tumor reactive. In
contrast, TILs cultured in control media significantly lose clonal diversity
and displayed Simpsons
clonality of approximately 0.4 (i.e., a significantly less diverse clonality,
indicating that many
tumor reactive clones are lost in the culturing process using control media)
(FIG. 12).
[0579] Differential abundance (DA) plots were generated using
the data presented in FIG.
12 (ImmunoSeq, Adaptive Biotechnolgies). Such DA analysis calculates TCR
overlap (see, e.g.,
Emerson et al, J. Path. (2013), which is incorporated by reference herein in
its entirety), Morisita's
Index, and the Jaccard Index for any pair of samples. These plots show that
the differential
abundance of clones are significantly different between tumor vs TILs expanded
in control media
(FIG. 13A) as compared to tumor vs TILs expanded in MRM (FIG. 13B).
[0580] The Tit repertoire present in tumor fragments were
represented approximately 4-
fold more in Tits cultured in MRM process compared to TILs cultured in control
media. When
expanded, TILs are typically outgrown by infrequent clonotypes with
preferential proliferative
potential (these clones are shown expanded along the y-axis in FIGs. 13A-13B).
In contrast, TILs
cultured in MR1\4 showed significantly better preservation and expansion of a
wider repertoire of
clonotypes that are present in the tumor. The preservation and expansion of
clonal diversity of the
TIL population is critical for optimization for effective therapy.

WO 2023/077034
PCT/US2022/078827
- 207 -
[0581] To further analyze TIL clonal diversity, the top 50 most
dominant prevalent TCRs
in initial tumor digests were compared to TILs expanded in control media
versus MRM. Culture
in MRM preserves both dominant (i.e. prevalent) and rare T1L clonotypes. The
density of lines in
FIG. 13D show that the majority of T cell clones expanded in MRI\4 recognize
tumor antigens
where they do not in T cell clones cultured in control media (FIG. 13C). The
majority of dominant
tumor clones are recognized by T cell clones expanded in MRM, as indicated by
the connections
above the dotted line of FIG. 13D, as compared to the T cell clones cultured
in control media (FIG.
13C). Of the top 50 dominant tumor TCRs, 2% are preserved in TILs cultured in
control media
(FIG. 13C) as compared to 57% in Tits cultured in MRM (FIG. 13D). These data
demonstrate
that MRM expanded TILs retain a more faithful representation of initial tumor
TCR clonotypes
than TILs expanded in control media.
Example 7. MRM preserves tumor reactivity of TILs
[0582] The ability of TILs generated using the methods described
herein to preserve KRAS
mutant reactivity was evaluated. TILs expanded in control media or MRM were
mixed with
autologous dendritic cells (DCs) that had been pulsed with mutant KRAS
peptide. After 10 days
total genomic DNA was isolated from the TILs using DNeasy Blood and Tissue Kit
(Qiagen) and
the TCR-Vb CDR3 motif was sequenced and analyzed using Immuno-seq for TCRI3
and CDR3
regions (Adaptive Biotechnologies, Seattle, WA). FIG. 14 shows that TILs
cultured in MRM
preserve KRAS mutant reactivity, whereas TILs cultured in control media are
not able to do so.
Specifically, TILs cultured in MRM shared similar CDR3 amino acid motifs as
seen in Tits from
the tumor fragment. These were not detected in TILs cultured in control media.
Thus, the data
show that culture in MRM preserves TIL clonotypes that are represented in the
original tumor
fragment.
Example 8. TILs generated using MRM demonstrate increased tumor recognition
and
tumor killing
[0583] TILs obtained from a melanoma tumor were obtained and
expanded with either
control media or MRM as described above. An autologous tumor cell line was
derived from the
same melanoma sample as the TILs. Briefly, the melanoma cell line was
generated by
enzymatically digesting a fragment of melanoma (using collagenase and DNAse),
plating the
resulting single-cell suspension, followed by serial passaging of the
outgrowing cells. The ability
of the TILs derived from the melanoma tumor to generate inflammatory cytokines
in response to
the melanoma derived cell line was assessed. TILs generated using either
control media or MRM
CA 03234821 2024-4- 11

WO 2023/077034
PCT/US2022/078827
- 208 -
were co-cultured with the autologous melanoma cell line for 24 hours. 100,000
tumor cells from
the autologous melanoma cell line were plated in a 48 well plate in 300 ul of
complete RPMI media
(w/ 10% FBS) and allowed to incubate overnight. The next day, the supernatant
was removed and
TILs were added (some TILs were plated in the absence of tumor cells as a
control). After 24 hrs,
media supernatant was collected from the wells and secreted interferon gamma
and TNF-alpha was
measured using MSD. In addition, TILs generated with MRM were incubated in
control media
overnight, and IL-2 secretion was assessed by MSD. These data show that TILs
expanded using
MR_M exhibit significantly increased ability to respond to autologous tumor
cells in terms of
inflammatory cytokine production (FIGs. 15A-15B). Moreover, the Tits generated
using MRM
secrete significantly more IL-2 at steady state with no stimulation indicating
that these cells are
more fit.
[0584] The ability of the TILs derived from the melanoma tumor
to kill the melanoma
derived cell line was also assessed. The number of live tumor cells remaining
after co-culture was
assessed by detaching the tumor cells with trypsin and counting live cells by
flow cytometry. Based
on this live tumor cell count, percent tumor killing by the TILs (normalized
to wells of tumor cells
that did not experience TIL co-culture) was calculated. TILs generated using
MRM show a
significantly better ability to kill the tumor cells (FIG. 15C).
[0585] The above experiment was repeated as described above,
however some wells were
treated with the W6/32 antibody to block HLA Class I interactions. FIG. 15D
demonstrates that
the recognition of autologous tumor cells by TILs generated using MRM is
dependent on HLA
Class I interactions since blocking Class I eliminates the increase in
interferon gamma production.
Example 9. TIL clearance of tumor cells ex vivo
[0586] Patient autologous melanoma tumor cells were plated at
10,000 cells/well in the
xCELLigence impedance assay well plate. The following day, matched TILs that
were expanded
in control media or MRM were added to the plate at various effector T cell (E)
to tumor cell (T)
ratios, including 1:1, 2.1, and 4.1. TIL clearance of tumor cells was
monitored over time. FIG. 16
shows that TILs cultured in MRM displayed superior tumor cell lysis in an ex
vivo assay as
compared to TILs cultured in control media across a range of relative doses,
with a 4:1 ratio of
effector T cells cultured in MR_I\4 to tumor cells resulting in complete tumor
eradication.
Example 10. Analysis of stemness of tumor cells ex vivo
[0587] Non-small cell lung cancer (NSCLC) TILs produced
following standard TIL
expansion methods were compared to TIL produced in MRM, according to the
methods disclosed
CA 03234821 2024-4- 11

WO 2023/077034
PCT/US2022/078827

herein. While the control process generated TILs highly enriched for CD8+ T
cells, these cells
were not enriched for a stemlike CD8+CD39-CD69- T cell population and
expressed low levels of
central memory markers and co-stimulatory receptor, CD27 (FIGs. 17A-17D). The
control
expansion process generated T cell products with enriched stemlike CD8+CD39-
CD69- T cells
and higher expression of co-stimulatory receptor CD27, but resulted in reduced
expansion of CD8+
T cells. TILs cultured in MRM yield highly enriched populations of CD8 I T
cells with enhanced
abundance of CD8+CD39-CD69- stemlike T cells, central memory markers
(CD45RO+CD62L+),
and markedly higher expression of co-stimulatory receptor CD27 (FIGs. 17E-
17H). Collectively
these markers demonstrate attributes of stem-like cells that are correlated
with clinical responses.
[0588] TIL products with enhanced stemlike properties, including
retention of key co-
stimulatory receptors CD27, elongated telomeres, memory cell phenotypes and
the presence of
populations of cells enriched with CD391CD69- CD8+ T cells, are associated
with improved
clinical responses. Additional differentiation state-linked characteristics of
T cells, including
ability to secrete polyfunctional cytokines, and expression of co-stimulatory
receptor CD28 have
also been correlated with anti-tumor potency. TILs expanded in MRM exhibit
favorable
phenotypic attributes, including an increased abundance of CD8+CD39-CD69- T
cells when
compared with control TIL expansion process in melanoma, NSCLC, and colorectal
cancers (FIGs.
18A-18C).
Example 11. TIL culture in MR1V1
[0589] The data presented herein show that culturing TILs in a
culture medium comprising
increased potassium generates a TIL population that has increased expansion of
CD8+ TILs and
increased sternness, relative to TILs cultured in medium having lower levels
of potassium (e.g.,
less than about 40 mM potassium ion, e.g., 5 mM potassium ion). Further, data
suggest that
exceedingly high levels of potassium (e.g., greater than about 80 mM, greater
than about 90 mM,
or greater than about 100 mM potassium ion) in the culture medium can lead to
decreased TIL
yield, likely due to decreased TIL growth and expansion, data not shown. To
further characterize
the effects of MRM on TIL culture, (1) TILs will be cultured in control medium
(an isotonic RPMI
formulation comprising 55 mM potassium ion) during an initial expansion stage
followed by
culture in MR1V1 medium comprising between 50-70 mM (e.g., 50 mM, 55 mM, 60
mM, 65 mM,
or 70 mM) potassium ion and between 50-70 mM (e.g., 50 mM, 55 mM, 60 mM, 65
mM, or 70
mM) NaC1 during a final expansion stage, (2) TILs will be cultured in MRM
medium comprising
between 50-70 mM (e.g., 50 mM, 55 mM, 60 mM, 65 mM, or 70 mM) potassium ion
and between

-210 -
50-70 mM (e.g., 50 mM, 55 mM, 60 mM, 65 mM, or 70 mM) NaC1 during an initial
expansion
stage followed by culture in control medium during a final expansion stage;
and (3) TILs will be
cultured in MRM medium comprising between 50-70 mM (e.g., 50 mM, 55 mM, 60 mM,
65 mM,
or 70 mM) potassium ion and between 50-70 mM NaCl during an initial expansion
stage followed
by culture in MRM medium comprising between 50-70 mM (e.g., 50 mM, 55 mM, 60
mM, 65
mM, or 70 mM) potassium ion and between 50-70 mM (e.g., 50 mM, 55 mM, 60 mM,
65 mM, or
70 mM) NaCl during a final expansion stage. In all experiments, initial
culture conditions will
further comprise 6000 IU/mL IL-2, and final culture conditions will further
comprise 3000 IU/mL
IL-2. Tits cultured according to this method will be characterized for
expression of sternness and
effector markers, cytotoxicity, and yield.
Example 12 Analysis of Clonal Diversity
[0590] To assess the clonal diversity of TILs cultured in MRM,
according to the methods
disclosed above, tumor fragments and TILs obtained from the tumor fragments
(e.g., dissociated
tumor fragments) were cultured/expanded in either control media or metabolic
reprogramming
media (MRM). Total genomic DNA was isolated from tumor and TIL samples using
DNeasy
Blood and Tissue Kit (QIAGEN) and sequenced using Immuno-seq for TCRI3 and
CDR3 regions
(Adaptive Biotechnologies, Seattle, WA).
[0591] The diversity metrics of the non-small cell lung cancer
(NSCLC) and melanoma
samples were assessed by Simpsons clonality AiIpi2 where pi is the
proportional abundance of
clone i in a given sample. Simpsons clonality and productive rearrangements
were examined in
tumor fragments ("tumor"), Tits cultured in control media ("control"), and
TILs cultured in MRM
("MRM") for NSCLC and melanoma (FIG. 19A and FIG. 19B, respectively) TILs
cultured in
MRM (post-expansion) displayed Simpsons clonality of approximately 0.28 for
NSCLC and
approximately 0.38 for melanoma, which indicates high clonal diversity (FIG.
19A and FIG. 19B).
Maintenance of TCRI3 diversity represent preservation of TIL clonotypes that
infilatrated the
tumors and are tumor reactive. In contrast, TILs cultured in control media
significantly lose clonal
diversity and displayed Simpsons clonality of approximately 0.65 for NSCLC and
approximately
0.8 for melanoma (i.e., a significantly less diverse clonality, indicating
that many tumor reactive
clones are lost in the culturing process using control media) (FIG. 19A and
FIG. 19B).
Example 13: Large-Scale Expansion of TIL
[0592] The present example provides a sample protocol for the
large scale production of
less differentiated TILs. Tumor fragments are coarsely chopped in MRM media
(as described
CA 03234821 2024-4- 11

WO 2023/077034
PCT/US2022/078827
- 211 -
herein). Chopped tumor fragments are dissociated using the gMACS machine in
MRM media.
Dissociated cells are filtered and then either cryopreserved or taken directly
to pre-REP.
[0593] All cells from the dissociated tumor fragment are used at
Day 0 of the
manufacturing process. At day 0, all cells isolated from the patient's tumor
are seeded at a density
of 0.5 x 106/mL at 2 mL per well. The cells are then cultured in MRM
supplemented with IL-2 at
6000 IU/mL and IL-21 at 30 ng/mL. At pre-REP Day 4 the cells are split (1:1
vol:vol) if pII is <
7.1, and the culture medium is supplemented with 10 1 of TRANSACTTm and 14/mL
of 4-1BBL
per 2 mL of MRM cell culture media. At pre-REP Day 7, 8, or 9, split cells
(1:1) if pH is < 7.1. At
pre-REP Day 10, cells are counted. If about 30 million cells are present, the
cells are advanced to
secondary expansion. If less than 30 million cells are present, the cells are
split (1:1) if pH is < 7.1,
and pre-REP is continued for one more day. Pre-REP should not exceed 14 days.
[0594] Secondary expansion comprises two steps: static-REP and
dynamic-REP. Briefly,
TILs were isolated from tumor samples by mechanical and/or chemical
dissocation of the tumor
followed by pre-REP expansion, as described above. On day 4 of pre-REP, 4-1BB
ligand and
TRANSACTTh are added to the culture medium. Cells are harvested on day 10. If
less than 30
million cells are obtained at day 10, cells are allowed to culture for one or
two more days in the
pre-REP step.
[0595] Following pre-REP, TILs arc transferred to PL750 culture
bags for static-REP. TILs
are cultured in the presence of irradiated PBMCs (1:200) and OKT-3. The cell
culture bag(s) are
gently mixed and placed in a static incubator at 37 C and 5% C07 for a target
of 5 days. Upon
completion of the static-REP, cells are forward processed into the dynamic-
REP.
[0596] The dynamic-REP unit operation includes the inoculation
of a bioreactor and
expansion using cell culture media (MRM) The dynamic-REP unit operation is
performed to
expand the number of TILs to achieve dose requirements. A rocking motion
bioreactor
(BIOSTAT R1\4 TX, Sartorius) is used for expansion.
[0597] Based on the volume seeded in the static-REP, cell
culture media is added into the
bioreactor, and the bioreactor controls are set to predefined values.
[0598] After bioreactor setup, static-REP cells are inoculated
into the bioreactor to achieve
a working volume between 2 ¨ 3L. The culture is sampled and tested as part of
the in-process
testing. Upon conclusion of inoculation, the expansion recipe is initiated on
the Multifunctional
Control Software (MFCS) program that controls perfusion and volume addition in
the bioreactor.

WO 2023/077034
PCT/US2022/078827
- 212 -
[0599] The perfusion program begins with perfusion of 25% of the
working volume every
24 hours for the initial 48 hours of expansion. Sampling and testing will
occur daily throughout
the duration of dynamic-REP. After 2 days, volume increases, and increases to
perfusion volume
may begin based on the viable cell density achieved in the bioreactor. These
volume increases
occur by entering the new pre-determined setpoints into the MFCS program, and
the perfusion
volume will be increased to maintain a perfusion rate of 25% of the working
volume.
[0600] Once the reactor has achieved the max working volume of
5L, the perfusion rate is
increased to 50% of the working volume for the duration of the expansion.
[0601] After 9 days of expansion, the total viable cell count
will be used to determine if an
extension of additional 3 or 4 days of expansion will be applied, to help
achieve the number cells
required to meet the intended dose. After the dynamic-REP expansion is
completed, cells will
proceed to harvest.
[0602] The harvest unit operation objective is to end the cell
expansion phase of the process
and prepare the cells for formulation and fill. Once harvest criteria are met
based on the process
control strategy, the MFCS protocol will be terminated to conclude the
programmed perfusion
schedule. Using the Sartorius RIVITX Harvest Device, the reactor bag can be
inserted to gravity
draining the entire cell culture into a transfer bag. Once transferred, the
weight and cell count are
captured to determine the harvested culture TVC. The cells are spiked with HSA
(2% w/v) prior
to forward processing to formulation.
[0603] The drug product formulation unit operation is comprised
of washing, buffer
exchanging, and resuspending the expanded T1L product. The Sefia S-2000 and
respective sterile
single use kit is used to allow for automated concentration, wash, and buffer
exchange of the
expanded cell culture. Once the equipment and kit are setup the cells are
volume reduced to reduce
the up to 5.5 L culture down to less than 200 mL and spent cell culture media
is transferred to
waste. The cells are then washed with Plasmalyte containing 2% (w/v) HSA
before the cells are
concentrated to 1x109 cell s/mL and diluted with a 6%-7%DMS0 cryopreservation
buffer (mixture
of CryoStor CS10 and Cryostor 5) The final drug product volume is calculated
to achieve a
formulated drug product cell density of 200x106 cell s/mL, with additional
manual dilution, using
6%-7% DMSO cryopreservation buffer, executed in cases where the target
formulated volume is
greater than 300 mL maximum output volume of the Sefia. Once the Sefia and
additional dilution
as necessary is completed the formulated drug product is weighed, sampled for
release assays
according to the sample plan, and transferred into CryoMACS 250 bags. The
CryoMACS 250 bags
are filled to a target fill volume of 50 mL, and a final bag fill volume of
between 30 mL to 70 mL.

Once each bag is filled the excess air is removed from the bag and sealed
using a sealer designed
for EVA tubing. The sealed bags are placed individually in cassettes and
frozen via controlled rate
cryopreservation to ramp cells to -100 C. Once the control rate freezer
profile has completed the
frozen drug product cassettes and vials are transferred via temperature-
controlled storage device
and stored in LN2 until the therapeutic drug product can be administered to
the patient.
[0604] We assessed whether MR1\4 TIL products generated at
research (small) scale and
large scale are comparable. TIL from three metastatic melanoma tumors
underwent the 1VIR1\4
production at both small and large scale. The TIL products were analyzed for
CD4+:CD8+ T cell
composition, sternness characteristics (%CD39-CD69- and %CD27+) and exhaustion
(%PD1+) in
CD8+ T cells and sternness characteristics (%CD39-CD69-) in CD4+ T cells, with
no significant
differences observed (data not shown). Additionally, bulk RNAseq analysis
showed consistent
gene expression of stemness and exhaustion markers between small and large
scale Epi-R samples
(data not shown). These results indicate that TIL expanded using small and
large scale MRM
procedures have comparable phenotypes.
Example 14: Transcriptional Profiling of DO gMACS and TIL Products by CITE-Seq
[0605] Cryopreserved DO gMACS (i.e., single cell suspentions)
and TIL products (both
small and large scale) were processed post thaw for Cellular Indexing of
Transcriptomes and
Epitopes by Sequencing (CITE-Seq) analysis CITE-Seq allows simultaneous
measurement of
single cell RNA and cell surface protein.
[0606] Cryopreserved DO gMACS and TIL products were thawed and
processed for CITE-
seq on separate days. Cell viability and counts were assessed using the
Cellometer K2 Cell Counter
(Nexcelom). For sorting, cells were stained with Live/Dead eFluor780 reagent
for 10 min at RT,
blocked with 10% Human TruStain FcX blocking reagent for 10 min at 4 C,
followed by staining
with a mix of fluorochrome-conjugated antibodies against CD45, CD4 and CD8,
DNA-conjugated
Total-SeqC antibodies against multiple cell surface proteins, and unique
hashtag antibodies
containing DNA barcodes for 30 min at 4 C. LiveCD45+ T cells from DO gMACS,
and equal
proportion of LiveCD45+ CD4+ and LiveCD45+ CD8+ T cells from TIL products were
FACS
sorted into PBS containing 2% BSA using the BD FACSAriaTM Fusion Cell Sorter
(BD
Biosciences). Sorted cells from all uniquely barcoded samples with hashtag
antibodies were pooled
together and then counted using the Cellometer K2 Cell Counter (Nexcelom).
Pooled cells were
loaded into each channel of the Chromium Next GEM Chip K using a Chromium Next
GEM Single
Cell 5' v2 Reagent Kit (10x Genomics). After single cell capture and lysis,
cDNA was synthesized,

and along with DNA conjugated to antibodies bound to cell surface proteins,
amplified over 13
cycles according to the manufacturer's protocol (10x Genomics). The amplified
cDNA from
polyadenylated mRNA and the amplified DNA from cell surface protein antibody
barcodes were
separated by size selection for generating independent barcoded 5' Gene
Expression (GEX)
libraries and Antibody derived tag (ADT) libraries, respectively. The GEX and
ADT libraries
prepared from multiple channels of the Chromium Next GEM Chip K were
quantified, pooled, and
sequenced together using the NovaSeq 6000 System (Illumina). An average
sequencing depth of
at least 30,000 reads per cell for GEX libraries and at least 5,000 reads per
cell for ADT libraries
was obtained.
[0607] The CD8+ TIL product obtained according to the methods
disclosed herein in MRM
was found to be enriched for stem-like phenotype, by both bulk and single-cell
RNA-seq analysis.
TILs generated from culture in MR1VI had generally higher expression of genes
associated with a
stem-like phenotype, which were generally expressed at lower levels by TILs
generated using AIM
V or a control media (FIG. 20A). CITEseq + scTCRseq was also conducted on each
of the
products. Using the Rosenberg DN stem score and CD39 and CD69 protein
expression we
identified the stemlike populations in each product. The TMRM product has
significantly more
stemlike cells than both control and AIM V, as calculated by a 1 sided t-test
(FIG. 20B). The
proportion of stemlike cells was gerenerally higher in the CD8+ TIL product
obtained using MRM
as compared to control or AIM V (FIG. 20C; each data set representing an
individual donor). A
similar effect was also observed in the CD4+ TIL products (FIGs. 20G-201).
[0608] Gene sets used in the analysis described in this example
are shown in Table 3.

[0609] Metabolic Phenotype and Cell-Cycle
[0610] The CD8 I TIL product obtained according to the methods
disclosed herein in MRM
was also found to have a less exhausted phenotype. TILs generated from culture
in MRM had
generally lower expression of genes associated with a exhaustion, which were
generally expressed
at higher levels by TILs generated using AIM V or a control media (FIGs. 20D-
20E), and the
proportion of exhausted cells was gerenerally lower in the CD8+ TIL product
obtained using MRM
as compared to control or AIM V (FIG. 20F; each data set representing an
individual donor). A
similar effect was also observed in the CD4+ TIL products (FIGs. 20G, 20H, and
20J).
[0611] T-cell metabolism and immunological function are closely
connected: stem-like T-
cells predominantly use oxidative phosphorylation (OXPHOS) for energy
production, whereas in
effector T-cells glycolysis is preferentially utilized (Pearce et al., 2013,
Bourgeois et al., 2018).
Therefore, OXPHOS is considered more favorable in T-cell products. In
addition, Vardhana et al.,
2020 demonstrated that constant antigen exposure leads to altered metabolism
thereby limiting
intratumoral T-cell proliferation and self-renewal. The hallmark of this
altered metabolism is a
rapid induction of mitochondrial oxidative stress that limits the ability of T-
cells to engage in
oxidative phosphorylation, resulting in bioenergetic limitations that are
sufficient to block T-cell
proliferation.
[0612] To assess the metabolic fitness of the products, bulk
RNA-Seq analysis was
performed on CD45+CD8+TIL sorted from MRNI and Control products. The
comparison between
MRIVI and Control products was performed using bulk RNA-seq data from 4
donors. Gene set
enrichment analysis revealed that genes upregulated in MRM TIL product were
significantly
enriched for the OXPHOS, respiratory electron transport, and cholesterol gene
sets when compared
to Control TIL product (FIGs. 21A-21B). Additionally, genes downregulated in
the MRM TIL
product were significantly enriched for the glycolysis gene set. In addition,
enrichment of cell cycle
associated gene sets was also seen in the MRM TIL product when compared to the
Control TIL
product indicating that MRM product is capable of enhanced proliferation.
[0613] Tumor-Reactive Clones
[0614] CITEseq + scTCRseq was conducted on Day() gMACS t cells
from 6 donors.
Clustering using the R package Seurat was done by first normalizing the cells
by library size using

negative expression

and no CD3 protein

ribosomes excluded. Additionally, genes strongly correlated (pearson
correlation > .25) with G2M
and S phases of the cell cycle were also excluded from the variable features
list. Normalized
expression of the remaining variable features was scaled and G2M and S scores
for each cell were
regressed out using the function ScaleData. After running PCA using the RunPCA
function we
used the function RunHarmony to integrate cells across the 6 donors. The
harmony vectors were
used to create UMAP using the RunUMAP function and also used to identify
clusters using the
FindNeighbors and FindClusters functions. Clusters 8 and 12 were subclustered
using the
FindSubcluster function because of heterogeneous expression of exhaustion
associated markers
(FIGs. 22A-22H).
[0615] Putative tumor reactive clusters were identified based on
expression of exhaustion
associated markers (CXC13, CD137(4-1BB), CD279(PD-1), and TIGIT(VSTM3)) which
have
been identified in the publications cited above.
[0616] The Day gMACs samples were also sequenced using Adaptive
bulkTCR
sequencing' s survey depth. In addition to using the exhaustion phenotype as a
method for
identifying putative tumor reactive clones, we use the top 100 most frequent
clones as measured
using the bulkTCR sequencing.
[0617] FIGs. 23B and 23D show the number of putative tumor
reactive clones identified
in each sample based on the exhausted phenotype in the day() 5' CITEseq data
and bulkTCR
frequency (top 100 clones). Using bulkTCR data from each product we evaluated
the number of
tumor reactive clones preserved in each process. While each donor has a
variable # of tumor
reactive clones initially, the three processes preserve similar numbers of
putative tumor reactive
clones.
[0618] By summing all the frequencies of the putative tumor
reactive clones identified in
the bulkTCR products we estimate the percentage of the product coming from
putative tumor
reactive clones. We see that the percent of product that is putative tumor
reactive clones is
relatively consistent between processes (FIGs. 23A-23C). The CD8 putative
tumor reactive clones
(FIG. 23A) constitute a larger percentage of the product than the CD4 putative
tumor reactive
clones (FIG. 23C).

[0619] Next, we evaluated the presence of stemlike putative
tumor reactive cells by
identifying clones that have both a stemlike phenotype in the product and
putative tumor reactive
phenotype in the day() sample. The amount of clones identified in each donor
is consistent between
the different processes (FIG. 23E).
[0620] Using the putative tumor reactive clones we identified
using the exhaustion
phenotype and most frequent clones, we did pseudobulk differential expression
between the 3
processes, MRM, control, and AIM-V, to identify genes and functional programs
that are enriched
in the tumor reactive cells for the T1VIRIVI product. We used DESeq2 to model
the expression
difference between the products and used the test statistic output to as input
to fgsea to conduct
gene set enrichment analysis (GSEA). The GSEA showed that the TMRM putative
tumor reactive
cells up-regulate a memory phenotype when compared to both the AIM-V and TCM
putative tumor
reactive cells. Additionally, the MRM putative tumor reactive cells have lower
expression of
exhaustion associated gene sets (FIG. 24B). The heatmap shows significantly
differentially
expressed genes associated with exhaustion and effector memory phenotypes
(FIG. 24A). CD39
and CD69 protein is down-regulated and SELL and IL7R RNA are up-regulated in
MRM putative
tumor reactive clones (FIG. 24C). This indicates that the MRM putative tumor
reactive clones are
more stemlike than the other processes. Gating putative tumor reactive cells
on CD39 and CD69
protein expression to identify double negative (stem like) and double positive
(exhausted) cells
shows that the MRM putative tumor reactive cells have a lower proportion of
double positive
putative tumor reactive cells than Control and AIM V (FIGs. 24D-24F).
[0621] Autologous TIL Co-culture
[0622] Autologous tumor cell lines from patient tumor samples
were generated by cutting
a fraction of the tumor into 2 to 3 small pieces using a sterile scalpel. The
tumor fragments were
then incubated in 2.2 ml of pre-warmed plain RPMI/Glutamax with the addition
of 100u1 of
Enzyme H, 50u1 of Enzyme R and 12.5u1 of Enzyme A (Tumor Dissociation Kit,
Miltenyi, # 130-
095-929) in a 50m1 conical tube. The tumor and enzyme mix was incubated in a
37 C incubator
with occasional vortexing until media became turbid and tumor fractions became
more
disintegrated (1 to 2 hours). After the incubation time, 8 ml of pre-warmed
RPMI/Glutamax was
added to the 15m1 conical tube to dilute the enzymes and the tumor dissociate
was filtered through
a 70[tm filter into a fresh 50m1 conical tube. Cells were spun down at 300xg
for 7 min and then
resuspended in 10 ml of pre-warmed RPMI/Glutamax+ 10% FBS+ 1% Pen/Strep and
plated onto
a 10cm tissue culture dish and incubated at 37 C. One to two days post-
plating, the cells were
observed to assure tumor cell adherence and media was changed. Upon stromal
outgrowth (1-2

weeks post-plating), the cells were re-plated onto an NCCD-coated 10cm dish
and incubated in
Primary Cancer Cell Medium D-ACF (Primary Cancer Culture System, PromoCell, #
C-28081).
Media was replaced every 5 days and cells were observed for tumor cell
outgrowth. Four to six
weeks later, when colonies of tumor cells were present, the cells were
replated onto a new NCCD-
coated dish by differential trypsinization. This was continued until no more
stromal cells were
present. At the end, the tumor cells were taken off the Primary Cancer Culture
System and cultured
in RPMI/Glutamax+ 10% FBS-I- 1% Pen/Strep until needed for assays or were
viably
cryopreserved.
[0623] Twenty-four hours prior to TIL co-culture experiments,
autologous tumor cells
were plated onto a 96 well E-plate (Agilent, #300600910) at 30,000 cells per
well and co-culture
experiment was performed using the xCELLigence RTCA manufacturer's recommended
protocol.
Briefly, 501.1.1 of pre-warmed RPMI/Glutamax (+10% FBS) was added into each
well of a 96-well
E-plate. An initial scan of the wells was performed in the xCELLigence RTCA MP
(Agilent) and
then tumor cells were seeded into the wells of the plate. The plate was
incubated at room
temperature for 30 min to allow the cells to settle. After the incubation, the
plate was placed back
into the xCELLigence and impedance measurements were obtained every 15 min.
The plate was
incubated overnight in the xCELLigence platform until a cell index of 1-1.5
was reached,
indicating 90-100% confluency. The next day, TILs that were rested overnight
in control media
supplemented with IL-2, were washed twice with RPMI/Glutamax (+10% FBS),
counted and
plated onto the tumor cells cells at an E:T ratio of 1:1, 5:1 and 10:1 in
RPMI/Glutamax (+10%
FBS) (FIG. 25A) or at an E:T of 10:1 (AIM-V, MRM, MRM no pre-REP boost with 4-
1BB ligand
and TRANSACTTm, and Control; FIG. 25B). Tumor cytolysis readings were obtained
by the
xCELLigence every 15 min until the end of the experiment (-30 hours).
[0624] Cytotoxicity was observed in a dose-dependent manner
(FIG. 25A) with all
processes, indicating the preservation of anti-tumor functionality (FIG. 25B).
No-boost MRM had
the most superior tumor killing compared to Control, MRM, and AIM-V (FIGs.
25B). These data
indicate that while recognition was seen with all media conditions, MRM-
expanded TIL
outperformed AIM-V in recognition. Additionally, the no-boost MRM condition
exhibited
substantially better tumor reactivity than either control.
[0625] Product cells from MRM, MRM no boost, AIM-V, and control
were then co-
cultured with corresponding autologous tumor cell line for 4 hours and then
sequenced along with
control products. Clones that were identified as tumor reactive were
identified by 4-1BB
(TNFRSF9) expression, which was defined as greater than background control
expression (shown
CA 03234821 2024-4- 11

WO 2023/077034
PCT/US2022/078827
- 226 -
for 41BB as > 2; FIGs. 26A-26C). The amount of tumor reactive clones
identified in each co-
cultured product was consistent with FIG. 25A, where MRM no boost showed the
most killing also
had the most tumor reactive clones. Differential expression between the tumor
reactive clones in
the control product identified an enriched effector memory (GNLY, ZNF683,
PRF1) and reduced
exhaustion phenotype (LAG3) in MRM, similar to the differential expression
shown with putative
tumor reactive clones (FIG. 26D). Differential expression was done using the
FindMarkers
function in Seurat.
Example 15: Characterization of TILs Cultured in MRM
[0626] Fresh or viably cryopreserved single cell suspensions
prepared from metastatic
melanoma, NSCLC and colorectal metastatic tumors underwent TIL expansion using
standard,
control, and MRM processes. Both process variants included 2 steps: (A) A pre-
rapid expansion
protocol (REP) culture and (B) a REP culture. Historically, the pre-REP
expansion of TIL has been
performed utilizing high concentrations of IL2 (60001U/ml) over 3 to 5 weeks.
High levels of IL2
are thought to be required for promoting the expansion of dysfunctional TIL.
This traditional pre-
REP TIL expansion only includes one activation signal, resulting in a long
expansion duration to
achieve sufficient cell numbers for initiating the secondary REP expansion.
The MRM TIL
expansion process described herein incorporates a pre-REP boosting step, in
which TIL are
stimulated with TRANSACTTm and 4-1BB ligand on day 4 of culture to promote T
cell
proliferation. Standard and control TIL did not undergo this boosting step and
were expanded in
IL2-containing media. The MRM process resulted in a higher rate of success in
expanding Tit
compared to control processes. Pre-REP TIC, expansion greater than 1.5-fold
was considered a
successful expansion. Across all tumors studied, the overall success rate of
pre-REP expansion of
TIL cultures was 41% (7/17) in AIM-V media, 75% (12/17) TCM media, and 100%
(17/17) for
the MRM process (FIGs. 27A-27C). Further analysis was performed to assess the
performance of
each expansion process in each of the studied tumor indications (melanoma,
NSCLC and CRM)
(FIGs. 27D-27F). The overall success rate of pre-REP TIL expansion was higher
in the settings of
metastatic melanoma and NSCLC compared with CRM, likely due to higher T cell
infiltration of
these cancer types. Importantly, in each tumor type, the MRM process exhibited
improved
performance in successful pre-REP TIL expansions.
[0627] REP fold expansion was similar between control and MRIVI
process, both of which
were higher than the standard (FIG. 27G). Irradiated PBMC (feeder cells) from
healthy donors
were used in the REP process to enhance TIL proliferation while maintaining
cell viability. As

these allogeneic feeder cells represent potential contamination risks in the
final product, it is
important to ensure these cells are unable to proliferate after irradiation.
Irradiated feeder cells and
non-irradiated healthy donor pooled PBMCs were labelled with cell trace violet
(CTV) dye to track
proliferation upon a-CD3 stimulation. Cells were stimulated using 30ng/m1 a-
CD3 (OKT3 clone)
in media containing 1500IU/m1IL2. Non-irradiated healthy donor PBMC were able
to proliferate,
while irradiated feeder cells were unable to proliferate based on CTV dilution
assay (FIGs. 2711-
271).
[0628] Gating strategy
[0629] To perform phenotypic analysis of the products, cells
were stained for flow
cytometry analysis to measure cell surface expression of relevant protein
markers. Lymphocytes
were first gated by FSC-A vs SSC-A, then singlets by FSC-A vs FSC-H, then live
cells by
exclusion dye against F SC-A, then CD3+ T cells by CD3 vs FSC-A. In some
product analyses,
CD4+ and CD8+ T cells were sub gated and compared separately between
conditions. The CD8+
T cells were analyzed for sternness characteristics by plotting CD39 against
CD69 and gating on
the double positive population (CD39+CD69+) and double negative population
(CD39-CD69-).
CD39-CD69- T cells are stem-like cells as defined by previous literature.
CD39+CD69+ T cells
are highly differentiated cells. For co-stimulatory positive stern-like cell
populations in the CD8+
T cell subset, CD62L and CD27 or CD27 and CD127 were plotted against each
other.
CD62L+CD27+CD8+ and CD27+CD127+ CD8+ T cells were defined as co-stimulatory
positive
stem-like cells (FIG. 28). Favorable phenotypic attributes included
CD3910/CD6910
,
CD27high/CD62Lhigh, CD27high/CD127high, CD39dim/CD691' and CD39high/CD691'.
[0630] TheMRM process promotes a CD8+ T cell dominated product
[0631] Mature human alpha-beta T cells can be broadly classified
based on their exclusive
co-receptor expression; either CD4 expressing (CD4+) or CD8 expressing (CD8+).
CD4+ T cells
recognize antigen presented on HLA Class II by professional antigen presenting
cells (pAPCs) and
can be classified into several different subsets, including Th2 subsets, CD4+
helper T cells which
promote CD8+ T cell function and regulatory T cells that suppress immune
responses. CD8+ T
cells predominantly drive target cell killing cytolysis through specific
recognition of cognate
antigens presented by HLA Class I molecules. In the context of tumor
immunotherapy, while direct
recognition of tumor antigens by CD4+ T cells is sometimes limited by a lack
of tumor expression
of HLA Class IT, CD8+ T cells are capable of' recognizing tumor antigen
presented in the context
of HLA Class I directly on tumor cells, as well as (pAPCs). Therefore,
infusion of high numbers

of CD8+ T cells with the capacity to directly kill tumor cells may be linked
with improved clinical
anti-tumor responses, as has been documented in human melanoma patients (Iran
et al., 2014).
[0632] We assessed the ratio of CD4+ and CD8+ T cells in our TIL
products using flow
cytometric analysis. While the ratio of CD4+ and CD8+ T cells varied by
patient sample, we
observed that MRM expansion of T1Ls promoted an increased abundance of CD8+ T
cells (FIG.
29A) and a corresponding decrease in the abundance of CD4 I T cells (FIG. 29B)
in the MRM
product relative to the standard and control expansion processes.
[0633] The MRM process better maintains stem like receptor
positive TILs
[0634] Upon antigen-recognition, naive T cell undergo activation
and a path of
differentiation to acquire functions for lasting effector immune response.
Some T cells differentiate
into short term effector cells, driving a robust immune response before dying
off. Other T cells
acquire memory phenotypes, which allow them to survive longer term and become
endowed with
relatively rapid recall responses should they re-encounter antigen. There is a
path of differentiation
within the memory T cell pool, resulting in multiple memory T cell subsets.
There exist a number
of hypotheses regarding the lineage of these memory T cell subsets, but the
younger or more stem-
like T memory cells are generally thought to progressively differentiation
into the terminally
differentiate subset, after which they die off Each subset has distinct
attributes and surface
markers, summarized in Table 4.

[0635] Factors such as ICI{ signal strength, antigen abundance
and exposure, and the
inflammatory milieu will impact composition T cell memory pool. Given that
most T memory cells
in the tumor are experiencing repeated antigen exposure, we would expect the
most stem-like
subset of memory T cell in our TIL culture to be TCMs.

WO 2023/077034

[0636] Within each subset, a range of sternness can be
maintained, i.e., TCMs can exhibit
higher or lower levels of CD27. However, the stem-like quality of cells is
best observed when
using a combination of stem-like markers. For example, CD62L alone can be a
marker on both
memory bystander or naïve T cells, but used in combination with CD45RO, it can
mark more stem-
like TCM cells. We assess the proportion of these stem-like receptor positive
cells to compare the
stem-like attributes of our MRM TIL product versus the control TIL product.
[0637] The enhanced presence of certain stem-like receptor
positive populations in TIL has
been correlated with favorable clinical responses. For example, in patients
with checkpoint therapy
treated melanoma, CD27 and CD62L expression on CD8+ TIE, was higher in
patients with
complete remissions and partial responses compared to non-responding patients
(van den Berg et
al, 2020). Similarly, another study in metastatic melanoma patients receiving
TIL ACT showed
taht the degree of response (complete, partial, no response) was strongly
correlated with expression
of CD27 on CD8+ T cell in the infusion product (Rosenberg et al, 2011). CD127,
aka IL7 receptor,
was found to be more highly expressed in the neoantigen-specific T cells of
NSCLC patients with
a maj or pathological response versus those of NSCLC patients with no major
pathological response
(Caushi et. al, 2021).
[0638] We found that MR1\4 TIL product harbored a significantly
higher percentage of
CD62L+CD27+ (FIGs. 30B-30C) and CD27+CD127+ (FIG. 30D) CD8 T cells.
Furthermore,
MR1V1 TIL product also had higher CD27+ alone on CD8 T cells (FIG. 30A). Taken
together, the
heightened expression of these stem-like receptors on the CD8 T cells in our
MIRM TIL product
compared to the control product would suggest that our infusion product is
poised to improve
clinical responses over standard TIL products.
[0639] The MRM process enriches less differentiated TILs
[0640] The co-expression of CD39 and CD69 on CD8 TIL has
recently been identified as
a readout for their sternness, persistence, and, ultimately, favorable
clinical responses to ACT
therapy in melanoma patients. Analysis of the TIL ACT product from responder
and non-responder
patients revealed that TIL product in responders was enriched in CD39-CD69-
CD8 T cells. In
turn, stratifying the patients by abundance of CD39-CD69- CD8 T cells
effectively separated the
patients by survival, with higher CD39-CD69- CD8 T cells identifying the
surviving patients.
Further analysis of this population exhibited sternness properties, including
self-renewal capacity
persistence post-infusion. On the other hand, CD39+CD69+ TIL exhibited a more
differentiated
and exhausted phenotype. Tumor antigen responsive T cells were detected in
both populations, but
were notably higher in the CD39+CD69+ subset (Krishna, 2020).

[0641] We turned to flow analysis to assess whether the MRM TIL
product contained a
higher percentage of CD39-CD69- CD8 T cells, and in turn, a lower percentage
of CD39+CD69+
CD8 T cells compare to the control product. MRM TIL product exhibited at least
three-fold more
CD39-CD69- CD8 T cells compared to the control product (FIGs. 31A-31B). On the
contrary,
MRM product contained more than two-fold fewer CD39+CD69+ CD8 T cells (FIG.
31C).
[0642] The effect of the MRM TIL production in not restricted to
CD8 T cells. We analyzed
the CD4+ T cells in both control and MRM products and found a similar pattern
as for CD8+ T
cells, whereby MRM enriched CD39-CD69- subset (FIG. 32A) and reduced
CD39+CD69+
population (FIG. 32B) compared to the control product. Since CD4 T cells bear
tumor-reactive
clones, and provide T cell help to improve CD8+ T cell cytolysis, their
presence and sternness
attributes in the MR1\4 TIL product could improve the anti-tumor responses by
the majority CD8
T cell population.
[0643] The MR1\4 product retains TIL polyclonality
[0644] Expansion success and enrichment of stern-like co-
receptor positive TILs by MRM
process prompted us to explore its impact on the T-cell repertoire. Initial
tumor materials can have
diverse TCR repertoire at different frequency. Due to existence of multiple
tumor reactive T cells
in the initial tumor material it is necessary to maintain diverse TCR
repertoire during ex-vivo
expansion. It is worth noting that each T cell clone has different capability
to proliferate. One of
the metrics used to understand and interpret the diversity of these cells is
clonality. To assess the
polyclonality of MRM TIL after expansion, next-generation sequencing of the
CDR3 variable
region of the TCR in MRM, standard and control TIL was performed. The Simpson
clonality
coefficient was calculated for each sample to quantitatively measure T-cell
polyclonality. In this
calculation, a value of 0 represents a completely evenly distributed sample
and 1 represents a
monoclonal sample. Therefore, Simpson clonality coefficient values nearer to 0
are more desirable
for a TIL product. The Simpson clonality was comparable between both the
control and MRM
processes (FIG. 33), suggesting that the increase in CD8+ T cells with stem-
like attributes driven
by MRM TIL expansion did not come at the expense of a loss of clonal diversity
in the final TIL
population.
Example 16: Analysis of TCR Diversity of Tits Expanded with MRM for Large
Scale and
Research Scale
[0645] To assess the clonal diversity of TILs from NSCLC,
melanoma, and colon cancer
expanded in MRM at research and large scale, according to the methods
disclosed above, tumor
fragments and TILs obtained from the tumor fragments (e.g., dissociated tumor
fragments) were

expanded in metabolic reprogramming media (MRM). Total genomic DNA was
isolated from
tumor and TIL samples using DNeasy Blood and Tissue Kit (QIAGEN) and sequenced
using
Immuno-seq for TCRI3 and CDR3 regions (Adaptive Biotechnologies, Seattle, WA).
[0646] The diversity metrics were assessed by Simpsons clonality
AlIpi2 where pi is the
proportional abundance of clone i in a given sample. Simpsons clonality and
productive
rearrangements were examined in dissociated tumor fragments ("tumor") and TILs
cultured in
MRM ("MRM") for NSCLC, melanoma, and colon cancer (FIG. 35A). As shown in FIG.
35A,
TILs expanded in 1VIRI\4 at research scale exhibited preserved polyclonality
(as evidenced by the
comparable Simpson clonality coefficient) when compared to the clonal
diversity of the source
tumor tissue. As shown in FIG 35B, TIL cultured using the MEM process
described herein to
produce large-scale products exhibit even more polyclonalality than TILs
cultured using MRM at
research scale.
Example 17: Analysis of Cytolytic Activity and Pro-Inflammatory and
Immunosuppressive
Cytokine Secretion
[0647] In addition, to assess the specificity and tumor killing
of TILs expanded with the
MRIV1 process, autologous tumor cells were co-cultured with MRM expanded TILs.
An autologous
tumor cell line was obtained as described above. Cells were plated at an E:T
ratio of 1:1, 1:5, and
10:1; tumor cells alone were used as a control. TILs produced with MRM
exhibited potent anti-
tumor function as measured in vitro using an autologous tumor cell line,
including dose-dependent
cytolytic activities and proinflammatory cytokine secretion in response to
stimulation by anti-
CD3/CD28 (FIG. 36A-36B). The ability to produce immunosuppressive cytokines
upon antigen
stimulation with anti-CD3/CD28 was assessed and showed a significant
difference between TILs
expanded with MRM and TIL expanded with the control process. As shown in FIG.
36C, Tits
expanded and cultured in MRM produced significantly lower amounts of
immunosuppressive 1L-
4, IL-5, and 1L-13 as compared to those TILs produced using the control
process.
[0648] The above results further highlight that the MRM process
described herein (for both
research and large scale and for tumors of different cancers) can be useful in
producing TILs that
are highly diverse and exhibit potent anti-tumor activity.
Example 18: Analysis of Polyclonality and Anti-Tumor Activity of TILs Cultured
in MRM
[0649] TIL that are highly enriched with tumor-reactive T cell
clones have been shown to
mediate responses to treatment (van den Berg JH, Heemskerk B, van Rooij N, et

Conventional TIL
products consist of a mixture of extensively differentiated T cells and low
levels of stem-like cells;
higher proportions of stem-like T cells have been associated with improved
outcomes in patients
treated with TIL (Krishna S, Lowery FJ, Copeland AR. Science. 2020;370:1328-
1334). To further
assess whether the culturing process described herein (e.g., in M_RM) can
improve one or more
properties of TILs, the following methods were used.
Identifying, Tracking and Analyzing Putative Tumor Reactive Clones
[0650] Using validated methods for analyzing putative tumor
reactive clones (Krishna S,
Lowery FJ, Copeland AR. Science 2020;370:1328-1334. Oliviera G, Stromhaug K,
Klaeger S, et
al. Nature. 2021;596:119-125), clones that are both high frequency and display
exhausted
characteristics in the dissociated tumor suspension of Day 0 tumor samples
(from melanoma, lung,
or colorectal cancer) were identified as putative tumor reactive (FIG. 34).
Identifying clones with
an exhausted pheneotype captured those clones that are most likely to be tumor
reactive, although
these clones could vary in their differentiation states in the final expanded
TIL (e.g., product). The
top 100 high frequency TCR clones were identified using bulk RNA-seq.
Exhausted cell TCR
clones were identified using single cell RNA-seq and single-cell TCR-seq. A
subset of 100 high
frequency clones that are also "exhausted" were identified as putative tumor
reactive cells. Bulk
TCR-seq was used to determine the presence and proportion of putative tumor
reactive clones in
the expanded TILs. Single-cell RNA and TCR-seq was then used to evaluate the
phenotype of the
tumor reactive clones in the expanded TILs.
Analysis of Putative Tumor Reactive Clones
[0651] To demonstrate tumor reactivity of putative tumor
reactive clones, putative tumor
reactive TCRs were transduced into healthy donor CD8+ T cells and the
transduced cells were co-
cultured with autologous tumor cells corresponding to the selected TCRs. Tumor
only was used as
a control. Tumor reactivity was measured by cytolysis and IFNy secretion 24

[0652] In addition, tumor reactivity was demonstrated in
putative tumor reactive clones
identified in MRM expanded TIL product produced at research scale and large
scale. The
expanded TIL product was co-cultured with either corresponding dissociated
tumor suspension or
corresponding tumor cell line. Tumor reactivity was measured by 41BB and IFNy
expression in
single-cell RNA/TCR-seq.

Example 19: Analysis of the Effect of MRM on Preserving Putative Tumor-
Reactive Clones
Identified in Initial Tumor Samples
[0653] Putative tumor reactive clones from each tumor (melanoma,
lung, and colorectal
cancer) expanded in MRIVI were identified from single cell suspensions of
dissociated tumor using
bulk TCR-seq as described above to identify high frequency clones. Using
single-cell RNA/TCR-
seq, tumor reactive clones (clones that have an exhausted phenotype) from
melanoma, lung and
colon cancer were identified by CXCL13, 4-1BB, PD-1, and TIGIT (FIG. 37A-37C).
Cells
identified by tumor reactive phenotype and high frequency in bulkTCR-seq were
characterized as
putative tumor reactive and biased towards CD8+ (FIG. 37D).
[0654] To demonstrate tumor reactivity of identified putative
tumor-reactive clones from
TIL expanded in MR1\4, as described above, the top three putative tumor-
reactive TCRs were
cloned into healthy donor T cells and co-cultured with the corresponding
autologous tumor cell
line. As shown in FIG. 38A, at a E:T ratio of 5:1, two of the three TCRs
showed 100% cytolysis.
The cytolysis data correlated with the specific secretion of IFNy as shown in
FIG. 38B.
[0655] Putative tumor reactive clones from TIL cultured and
expanded in MRM at research
scale and large scale were verified as tumor-reactive by co-culturing the
expanded TIL with a
corresponding target of either autologous tumor cell line or dissocoiated
tumor suspension and
measuring activation based on a 4-1BB+/TFNy+ phenotype The results shown in
FTG. 39
demonstrate that putative tumor-reactive clones expanded in MIRM using both
the large scale and
research scale process are tumor reactive when captured at high frequencies.
[0656] Furthermore, in accordance with the verified putative
tumor reactivily approach
described above, bulkTCR-seq analysis of TILs expanded using (a) the control
process, (b) MRM
process at research scale, or (c) MRM process at large scale from melanoma,
colon and NSCLC
tumor types was performed according to the methods described above. Although
bulkTCR-seq
showed that the MRM process for expanding TILs at reaseach scale and the
control process
preserve a comparable number of putative tumor-reactive clones, the large
scale MRM process
preserved an average of 94% of the identified putative tumor reactive clones
(data not shown).
[0657] Putative tumor reactive clones were identified in Day 0
dissociated tumor samples
by tumor reactive phenotype (CXCL13, 4-1BB, PD-1, and TIGIT (Pasetto et al.
CIR 2016, Lowrey
et al. Science 2022, Oliveira et al. Nature 2021). These putative tumor
reactive clones were then
analyzed by scRNAseq as described herein to identify the number of clones
preserved after
expansion using the control process or the MRM large-scale process, as shown
in Table 5.

[0658] The above results collectively demonstrate that the MRM
process described herein
preserves the putative tumor-reactive clones that exist within the initial TIL
population and that
these putative tumor-reactive clones are indeed tumor reactive.
Example 20: Analysis of the Effect of MRM on the Sternness of Putative Tumor-
Reactive
Cells Identified in Initial Tumor Samples
[0659] Next, to further assess the effect that the MRM process
has on improving various
properties of TILs, TILs were expanded and cultured using (a) the control
process, (b) the MIRM
process at research scale, or (c) the MRIVI process at large scale. Single-
cell RNA/TCR-seq analysis
was performed to characterize the phenotype of the putative tumor reactive
from 23 TIL products
(9 control, 9 MRM research scale, and 6 MRM large scale). The Uniform Manifold
Approximation
and Projection (UMAP) for all Tits expanded under conditions (a), (b), and (c)
is shown in FIG.
40A. The stem-like clusters for all TILs expanded under all conditions were
identified by
expression of SELL+, CD39-, and CD69- and gene sets listed in Table 3 and are
presented in FIG.
40B as a gradient of expression levels. FIGs. 40C-40D show that the putative
tumor reactive clones
were generally enriched in the non-stemlike clusters, as expected And, as
shown by the differential
expression of the many different genes associated with sternness or exhaustion
in FIGs. 41A and
41B, respectively, the MRM expanded putative tumor reactive Tits for both
large scale and small
scale exhibited increased sternness and reduced exhaustion when compared to
the control_ As
further support, GSEA identified up-regulation of sternness associated
genesets and down
regulation of exhaustion associated genes in TILs expanded using MRM at both
research (FIG.

41C) and large scale (FIG. 41D) as demonstrated by the Normalized Enrichment
Scores (NES) for
the various gene sets. And, as shown in FIG. 42, the percentage of CD8+
stemlike cells was higher
for TILs cultured and expanded in MRIVI at research scale and large scale
compared to TIL cultured
with the control process.
[0660] Collectively, the above results further demonstrate that
the global effect that the
MRIVI process provided herein has on TILs (e.g., increased stemness and
reduced exhaustion), is
seen specifically within the verified tumor reactive cell population of the
product. The results
provided here confirm that MRM processes described herein are useful in
generating TIL products
with improved properties, including tumor reactivity and stemness.
Example 21: Analysis of the Effect of MR1VI on Immune Checkpoint Inhibitor-
Treated and
Naïve Tumors
[0661] Advancement of immune checkpoint inhibitors has had
significant effect on cancer
therapeutics. However, increasing studies have suggested that certain tumors
can be resistant to
immune checkpoint therapy or become more resistant with treatment. See, e.g.,
Levi et al., Clin
Cancer Res 28(14): 3042-3052 (Jul. 2022). To demonstrate that the cell
compositions described
herein (e.g., TILs expanded and cultured in MRM) can be successfully expanded
and have a
comparable therapeutic effect on tumors that are refractory to immune
checkpoint inhibitors, TILs
from either naive tumors (i.e., not previously treated with an immune
checkpoint inhibitor) or
tumors previously treated with one or more immune checkpoint inhibitors were
expanded and
cultured using the control process or the MRM process described herein. Then,
both the stemness
and polyclonality of the resulting TILs were assessed using one or more of the
methods described
in the earlier examples.
[0662] As shown in FIGs. 43B and 43C, with the MRM process, the
TILs exhibited
increased sternness (as evidenced by increased percentage of CD39-CD69- cells)
and were more
skewed towards CD8+ T cells, as compared to the control process. This was true
regardless of
whether the TILs were from naïve tumors or tumors that were previously treated
with an immune
checkpoint inhibitor. And, as shown in FIG. 43A, as compared to the control
process, with the
MRM process, all ICB samples produced sufficient pre-Rep yields for further
expansion versus
only one of the samples in the control group.
