The invention provides systems and methods for determining and predicting the effect of providing a population of tumor infiltrating lymphocytes (TILs) on a condition associated with an entity, for example the effect of providing a population of tumor infiltrating lymphocytes (TILs) on a subject having cancer. The systems and methods rely on acquiring a computer readable analytical signature from a sample of the entity, obtaining a trained model output value for the entity by inputting the computer readable analytical signature into a tier trained model panel, and classifying the entity based upon the trained model output value with a time-to-event class in an enumerated set of time-to-event classes, each of whom is associated with a different effect of providing a population of TILs to the entity. The invention also provides methods of treating cancer in a patient by administering a therapeutically effective population of TILs to the patient, which is at the same determined to be likely to benefit from the administration of TILs comparative to other cancer patients that have been administered TILs. Such methods of treatment include obtaining from the patient a tumor fragment, contacting the tumor fragment with one or more cell culture mediums, thereby performing one or more expansions of population of TILs existing in the tumor, and producing one or more subsequent populations of TILs. The invention also provides methods of treating cancer in a patient exhibiting an increased or decreased level of expression of various biological markers such as proteins or protein groups described herein.
Treatment of bulky, refractory cancers using adoptive autologous transfer of tumor infiltrating lymphocytes (TILs) represents a powerful approach to therapy for patients with poor prognoses. Gattinoni, et al., Nat. Rev. Immunol. 2006, 6, 383-393. TILs are dominated by T cells, and IL-2-based TIL expansion followed by a “rapid expansion process” (REP) has become a preferred method for TIL expansion because of its speed and efficiency. Dudley, et al., Science 2002, 298, 850-54; Dudley, et al., J. Clin. Oncol. 2005, 23, 2346-57; Dudley, et al. J. Clin. Oncol. 2008, 26, 5233-39; Riddell, et al., Science 1992, 257, 238-41; Dudley, et al., J. Immunother. 2003, 26, 332-42. A number of approaches to improve responses to TIL therapy in melanoma and to expand TIL therapy to other tumor types have been explored with limited success, and the field remains challenging. Goff, et al., J. Clin. Oncol. 2016, 34, 2389-97; Dudley, et al., J. Clin. Oncol. 2008, 26, 5233-39; Rosenberg, et al., Clin. Cancer Res. 2011, 17, 4550-57.

The invention relates to determining the beneficial administration of T cells, for example tumor infiltrating lymphocytes (TILs), to a cancer patient, including systems and methods of determining such beneficial administration, and methods of treatment including administration of TILs to cancer patients likely to benefit from such administration. The methods include the use of the mass spectrum of the cancer patient's serum or plasma sample acquired pre-treatment, and a general purpose computer configured as a classifier which assigns a class label to the mass spectrum. The class label can take the form of “late,” or an equivalent label, e.g., “good,” or “early,” or an equivalent label, e.g., “bad,” with the class label “late” or “good” indicating that the patient is a member of a class of patients that are likely to obtain relatively greater benefit from TILs therapy compared to patients that are members of the class of patients having the class label “early” or “bad.” The particular moniker used for the class label is not particularly important. Predictive tests for a melanoma patient benefit from an antibody drug and related classifier development methods are described for example in International Patent Application Publication WO 2017/011439, the content of which is incorporated herein in its entirety. Progression-free survival, and/or overall survival, are indicators for assessing the benefit of TILs therapy. Hence, when considering the meaning of the labels late and early, or good and bad, the “relatively greater benefit” associated with the late or good label means a patient whose sample is assigned the late or good label is likely to have significantly greater, i.e., longer progression-free and/or overall survival than a patient with the early or bad class label.

Fry and Mackall, Blood 2002, 99, 3892-904. IL-7 can stimulate the development of T cells. IL-7 binds to the IL-7 receptor, a heterodimer consisting of IL-7 receptor alpha and common gamma chain receptor, which in a series of signals important for T cell development within the thymus and survival within the periphery. Recombinant human IL-7 suitable for use in the invention is commercially available from multiple suppliers, including ProSpec-Tany TechnoGene Ltd., East Brunswick, N.J., USA (Cat. No. CYT-254) and ThermoFisher Scientific, Inc., Waltham, Mass., USA (human IL-7 recombinant protein, Cat. No. Gibco PHC0071). The amino acid sequence of recombinant human IL-7 suitable for use in the invention is given in Table 2 (SEQ ID NO:6).
The term “IL-15” (also referred to herein as “IL15”) refers to the T cell growth factor known as interleukin-15, and includes all forms of IL-15 including human and mammalian forms, conservative amino acid substitutions, glycoforms, biosimilars, and variants thereof. IL-15 is described, e.g., in Fehniger and Caligiuri, Blood 2001, 97, 14-32, the disclosure of which is incorporated by reference herein. IL-15 shares β and γ signaling receptor subunits with IL-2. Recombinant human IL-15 is a single, non-glycosylated polypeptide chain containing 114 amino acids (and an N-terminal methionine) with a molecular mass of 12.8 kDa. Recombinant human IL-15 is commercially available from multiple suppliers, including ProSpec-Tany TechnoGene Ltd., East Brunswick, N.J., USA (Cat. No. CYT-230-b) and ThermoFisher Scientific, Inc., Waltham, Mass., USA (human IL-15 recombinant protein, Cat. No. 34-8159-82). The amino acid sequence of recombinant human IL-15 suitable for use in the invention is given in Table 2 (SEQ ID NO:7).
The term “IL-21” (also referred to herein as “IL21”) refers to the pleiotropic cytokine protein known as interleukin-21, and includes all forms of IL-21 including human and mammalian forms, conservative amino acid substitutions, glycoforms, biosimilars, and variants thereof. IL-21 is described, e.g., in Spolski and Leonard, Nat. Rev. Drug. Disc. 2014, 13, 379-95, the disclosure of which is incorporated by reference herein. IL-21 is primarily produced by natural killer T cells and activated human CD4+ T cells. Recombinant human IL-21 is a single, non-glycosylated polypeptide chain containing 132 amino acids with a molecular mass of 15.4 kDa. Recombinant human IL-21 is commercially available from multiple suppliers, including ProSpec-Tany TechnoGene Ltd., East Brunswick, N.J., USA (Cat. No. CYT-408-b) and ThermoFisher Scientific, Inc., Waltham, Mass., USA (human IL-21 recombinant protein, Cat. No. 14-8219-80). The amino acid sequence of recombinant human IL-21 suitable for use in the invention is given in Table 2 (SEQ ID NO:8).
The terms “antibody” and its plural form “antibodies” refer to whole immunoglobulins and any antigen-binding fragment (“antigen-binding portion”) or single chains thereof Δn “antibody” further refers to a glycoprotein comprising at least two heavy (H) chains and two light (L) chains inter-connected by disulfide bonds, or an antigen-binding portion thereof. Each heavy chain is comprised of a heavy chain variable region (abbreviated herein as VH) and a heavy chain constant region. The heavy chain constant region is comprised of three domains, CH1, CH2 and CH3. Each light chain is comprised of a light chain variable region (abbreviated herein as VL) and a light chain constant region. The light chain constant region is comprised of one domain, CL. The VH and VL regions of an antibody may be further subdivided into regions of hypervariability, which are referred to as complementarity determining regions (CDR) or hypervariable regions (HVR), and which can be interspersed with regions that are more conserved, termed framework regions (FR). Each VH and VL is composed of three CDRs and four FRs, arranged from amino-terminus to carboxy-terminus in the following order: FR1, CDR1, FR2, CDR2, FR3, CDR3, FR4. The variable regions of the heavy and light chains contain a binding domain that interacts with an antigen epitope or epitopes. The constant regions of the antibodies may mediate the binding of the immunoglobulin to host tissues or factors, including various cells of the immune system (e.g., effector cells) and the first component (C1q) of the classical complement system.
The term “antigen” refers to a substance that induces an immune response. In some embodiments, an antigen is a molecule capable of being bound by an antibody or a TCR if presented by major histocompatibility complex (MHC) molecules. The term “antigen”, as used herein, also encompasses T cell epitopes. An antigen is additionally capable of being recognized by the immune system. In some embodiments, an antigen is capable of inducing a humoral immune response or a cellular immune response leading to the activation of B lymphocytes and/or T lymphocytes. In some cases, this may require that the antigen contains or is linked to a Th cell epitope. An antigen can also have one or more epitopes (e.g., B- and T-epitopes). In some embodiments, an antigen will preferably react, typically in a highly specific and selective manner, with its corresponding antibody or TCR and not with the multitude of other antibodies or TCRs which may be induced by other antigens.
The terms “monoclonal antibody,” “mAb,” “monoclonal antibody composition,” or their plural forms refer to a preparation of antibody molecules of single molecular composition. A monoclonal antibody composition displays a single binding specificity and affinity for a particular epitope. Monoclonal antibodies specific to certain receptors can be made using knowledge and skill in the art of injecting test subjects with suitable antigen and then isolating hybridomas expressing antibodies having the desired sequence or functional characteristics. DNA encoding the monoclonal antibodies is readily isolated and sequenced using conventional procedures (e.g., by using oligonucleotide probes that are capable of binding specifically to genes encoding the heavy and light chains of the monoclonal antibodies). The hybridoma cells serve as a preferred source of such DNA. Once isolated, the DNA may be placed into expression vectors, which are then transfected into host cells such as E. coli cells, simian COS cells, Chinese hamster ovary (CHO) cells, or myeloma cells that do not otherwise produce immunoglobulin protein, to obtain the synthesis of monoclonal antibodies in the recombinant host cells. Recombinant production of antibodies will be described in more detail below.
The terms “antigen-binding portion” or “antigen-binding fragment” of an antibody (or simply “antibody portion” or “fragment”), as used herein, refers to one or more fragments of an antibody that retain the ability to specifically bind to an antigen. It has been shown that the antigen-binding function of an antibody can be performed by fragments of a full-length antibody. Examples of binding fragments encompassed within the term “antigen-binding portion” of an antibody include (i) a Fab fragment, a monovalent fragment consisting of the VL, VH, CL and CH1 domains; (ii) a F(ab′)2 fragment, a bivalent fragment comprising two Fab fragments linked by a disulfide bridge at the hinge region; (iii) a Fd fragment consisting of the VH and CH1 domains; (iv) a Fv fragment consisting of the VL and VH domains of a single arm of an antibody, (v) a domain antibody (dAb) fragment (Ward, et al., Nature, 1989, 341, 544-546), which may consist of a VH or a VL domain; and (vi) an isolated complementarity determining region (CDR). Furthermore, although the two domains of the Fv fragment, VL and VH, are coded for by separate genes, they can be joined, using recombinant methods, by a synthetic linker that enables them to be made as a single protein chain in which the VL and VH regions pair to form monovalent molecules known as single chain Fv (scFv); see, e.g., Bird, et al., Science 1988, 242, 423-426; and Huston, et al., Proc. Natl. Acad. Sci. USA 1988, 85, 5879-5883). Such scFv antibodies are also intended to be encompassed within the terms “antigen-binding portion” or “antigen-binding fragment” of an antibody. These antibody fragments are obtained using conventional techniques known to those with skill in the art, and the fragments are screened for utility in the same manner as are intact antibodies.
The term “human antibody,” as used herein, is intended to include antibodies having variable regions in which both the framework and CDR regions are derived from human germline immunoglobulin sequences. Furthermore, if the antibody contains a constant region, the constant region also is derived from human germline immunoglobulin sequences. The human antibodies of the invention may include amino acid residues not encoded by human germline immunoglobulin sequences (e.g., mutations introduced by random or site-specific mutagenesis in vitro or by somatic mutation in vivo). The term “human antibody”, as used herein, is not intended to include antibodies in which CDR sequences derived from the germline of another mammalian species, such as a mouse, have been grafted onto human framework sequences.
The term “human monoclonal antibody” refers to antibodies displaying a single binding specificity which have variable regions in which both the framework and CDR regions are derived from human germline immunoglobulin sequences. In an embodiment, the human monoclonal antibodies are produced by a hybridoma which includes a B cell obtained from a transgenic nonhuman animal, e.g., a transgenic mouse, having a genome comprising a human heavy chain transgene and a light chain transgene fused to an immortalized cell.
The term “recombinant human antibody”, as used herein, includes all human antibodies that are prepared, expressed, created or isolated by recombinant means, such as (a) antibodies isolated from an animal (such as a mouse) that is transgenic or transchromosomal for human immunoglobulin genes or a hybridoma prepared therefrom (described further below), (b) antibodies isolated from a host cell transformed to express the human antibody, e.g., from a transfectoma, (c) antibodies isolated from a recombinant, combinatorial human antibody library, and (d) antibodies prepared, expressed, created or isolated by any other means that involve splicing of human immunoglobulin gene sequences to other DNA sequences. Such recombinant human antibodies have variable regions in which the framework and CDR regions are derived from human germline immunoglobulin sequences. In certain embodiments, however, such recombinant human antibodies can be subjected to in vitro mutagenesis (or, when an animal transgenic for human Ig sequences is used, in vivo somatic mutagenesis) and thus the amino acid sequences of the VH and VL regions of the recombinant antibodies are sequences that, while derived from and related to human germline VH and VL sequences, may not naturally exist within the human antibody germline repertoire in vivo.
As used herein, “isotype” refers to the antibody class (e.g., IgM or IgG1) that is encoded by the heavy chain constant region genes.
The phrases “an antibody recognizing an antigen” and “an antibody specific for an antigen” are used interchangeably herein with the term “an antibody which binds specifically to an antigen.”
The term “human antibody derivatives” refers to any modified form of the human antibody, including a conjugate of the antibody and another active pharmaceutical ingredient or antibody. The terms “conjugate,” “antibody-drug conjugate”, “ADC,” or “immunoconjugate” refers to an antibody, or a fragment thereof, conjugated to another therapeutic moiety, which can be conjugated to antibodies described herein using methods available in the art.
The terms “humanized antibody,” “humanized antibodies,” and “humanized” are intended to refer to antibodies in which CDR sequences derived from the germline of another mammalian species, such as a mouse, have been grafted onto human framework sequences. Additional framework region modifications may be made within the human framework sequences. Humanized forms of non-human (for example, murine) antibodies are chimeric antibodies that contain minimal sequence derived from non-human immunoglobulin. For the most part, humanized antibodies are human immunoglobulins (recipient antibody) in which residues from a hypervariable region of the recipient are replaced by residues from a 15 hypervariable region of a non-human species (donor antibody) such as mouse, rat, rabbit or nonhuman primate having the desired specificity, affinity, and capacity. In some instances, Fv framework region (FR) residues of the human immunoglobulin are replaced by corresponding non-human residues. Furthermore, humanized antibodies may comprise residues that are not found in the recipient antibody or in the donor antibody. These modifications are made to further refine antibody performance. In general, the humanized antibody will comprise substantially all of at least one, and typically two, variable domains, in which all or substantially all of the hypervariable loops correspond to those of a non-human immunoglobulin and all or substantially all of the FR regions are those of a human immunoglobulin sequence. The humanized antibody optionally also will comprise at least a portion of an immunoglobulin constant region (Fc), typically that of a human immunoglobulin. For further details, see Jones, et al., Nature 1986, 321, 522-525; Riechmann, et al., Nature 1988, 332, 323-329; and Presta, Curr. Op. Struct. Biol. 1992, 2, 593-596. The antibodies described herein may also be modified to employ any Fc variant which is known to impart an improvement (e.g., reduction) in effector function and/or FcR binding. The Fc variants may include, for example, any one of the amino acid substitutions disclosed in International Patent Application Publication Nos. WO 1988/07089 A1, WO 1996/14339 A1, WO 1998/05787 A1, WO 1998/23289 A1, WO 1999/51642 A1, WO 99/58572 A1, WO 2000/09560 A2, WO 2000/32767 A1, WO 2000/42072 A2, WO 2002/44215 A2, WO 2002/060919 A2, WO 2003/074569 A2, WO 2004/016750 A2, WO 2004/029207 A2, WO 2004/035752 A2, WO 2004/063351 A2, WO 2004/074455 A2, WO 2004/099249 A2, WO 2005/040217 A2, WO 2005/070963 A1, WO 2005/077981 A2, WO 2005/092925 A2, WO 2005/123780 A2, WO 2006/019447 A1, WO 2006/047350 A2, and WO 2006/085967 A2; and U.S. Pat. Nos. 5,648,260; 5,739,277; 5,834,250; 5,869,046; 6,096,871; 6,121,022; 6,194,551; 6,242,195; 6,277,375; 6,528,624; 6,538,124; 6,737,056; 6,821,505; 6,998,253; and 7,083,784; the disclosures of which are incorporated by reference herein.
The term “chimeric antibody” is intended to refer to antibodies in which the variable region sequences are derived from one species and the constant region sequences are derived from another species, such as an antibody in which the variable region sequences are derived from a mouse antibody and the constant region sequences are derived from a human antibody.
A “diabody” is a small antibody fragment with two antigen-binding sites. The fragments comprises a heavy chain variable domain (VH) connected to a light chain variable domain (VL) in the same polypeptide chain (VH-VL or VL-VH). By using a linker that is too short to allow pairing between the two domains on the same chain, the domains are forced to pair with the complementary domains of another chain and create two antigen-binding sites. Diabodies are described more fully in, e.g., European Patent No. EP 404,097, International Patent Publication No. WO 93/11161; and Bolliger, et al., Proc. Natl. Acad. Sci. USA 1993, 90, 6444-6448.
The term “glycosylation” refers to a modified derivative of an antibody. An aglycoslated antibody lacks glycosylation. Glycosylation can be altered to, for example, increase the affinity of the antibody for antigen. Such carbohydrate modifications can be accomplished by, for example, altering one or more sites of glycosylation within the antibody sequence. For example, one or more amino acid substitutions can be made that result in elimination of one or more variable region framework glycosylation sites to thereby eliminate glycosylation at that site. Aglycosylation may increase the affinity of the antibody for antigen, as described in U.S. Pat. Nos. 5,714,350 and 6,350,861. Additionally or alternatively, an antibody can be made that has an altered type of glycosylation, such as a hypofucosylated antibody having reduced amounts of fucosyl residues or an antibody having increased bisecting GlcNac structures. Such altered glycosylation patterns have been demonstrated to increase the ability of antibodies. Such carbohydrate modifications can be accomplished by, for example, expressing the antibody in a host cell with altered glycosylation machinery. Cells with altered glycosylation machinery have been described in the art and can be used as host cells in which to express recombinant antibodies of the invention to thereby produce an antibody with altered glycosylation. For example, the cell lines Ms704, Ms705, and Ms709 lack the fucosyltransferase gene, FUT8 (alpha (1,6) fucosyltransferase), such that antibodies expressed in the Ms704, Ms705, and Ms709 cell lines lack fucose on their carbohydrates. The Ms704, Ms705, and Ms709 FUT8−/− cell lines were created by the targeted disruption of the FUT8 gene in CHO/DG44 cells using two replacement vectors (see e.g. U.S. Patent Publication No. 2004/0110704 or Yamane-Ohnuki, et al., Biotechnol. Bioeng., 2004, 87, 614-622). As another example, European Patent No. EP 1,176,195 describes a cell line with a functionally disrupted FUT8 gene, which encodes a fucosyl transferase, such that antibodies expressed in such a cell line exhibit hypofucosylation by reducing or eliminating the alpha 1,6 bond-related enzyme, and also describes cell lines which have a low enzyme activity for adding fucose to the N-acetylglucosamine that binds to the Fc region of the antibody or does not have the enzyme activity, for example the rat myeloma cell line YB2/0 (ATCC CRL 1662). International Patent Publication WO 03/035835 describes a variant CHO cell line, Lec 13 cells, with reduced ability to attach fucose to Asn(297)-linked carbohydrates, also resulting in hypofucosylation of antibodies expressed in that host cell (see also Shields, et al., J. Biol. Chem. 2002, 277, 26733-26740. International Patent Publication WO 99/54342 describes cell lines engineered to express glycoprotein-modifying glycosyl transferases (e.g., beta(1,4)-N-acetylglucosaminyltransferase III (GnTIII)) such that antibodies expressed in the engineered cell lines exhibit increased bisecting GlcNac structures which results in increased ADCC activity of the antibodies (see also Umana, et al., Nat. Biotech. 1999, 17, 176-180). Alternatively, the fucose residues of the antibody may be cleaved off using a fucosidase enzyme. For example, the fucosidase alpha-L-fucosidase removes fucosyl residues from antibodies as described in Tarentino, et al., Biochem. 1975, 14, 5516-5523.
“Pegylation” refers to a modified antibody, or a fragment thereof, that typically is reacted with polyethylene glycol (PEG), such as a reactive ester or aldehyde derivative of PEG, under conditions in which one or more PEG groups become attached to the antibody or antibody fragment. Pegylation may, for example, increase the biological (e.g., serum) half life of the antibody. Preferably, the pegylation is carried out via an acylation reaction or an alkylation reaction with a reactive PEG molecule (or an analogous reactive water-soluble polymer). As used herein, the term “polyethylene glycol” is intended to encompass any of the forms of PEG that have been used to derivatize other proteins, such as mono (C1-C10)alkoxy- or aryloxy-polyethylene glycol or polyethylene glycol-maleimide. The antibody to be pegylated may be an aglycosylated antibody. Methods for pegylation are known in the art and can be applied to the antibodies of the invention, as described for example in European Patent Nos. EP 0154316 and EP 0401384 and U.S. Pat. No. 5,824,778, the disclosures of each of which are incorporated by reference herein.
The terms “fusion protein” or “fusion polypeptide” refer to proteins that combine the properties of two or more individual proteins. Such proteins have at least two heterologous polypeptides covalently linked either directly or via an amino acid linker. The polypeptides forming the fusion protein are typically linked C-terminus to N-terminus, although they can also be linked C-terminus to C-terminus, N-terminus to N-terminus, or N-terminus to C-terminus. The polypeptides of the fusion protein can be in any order and may include more than one of either or both of the constituent polypeptides. The term encompasses conservatively modified variants, polymorphic variants, alleles, mutants, subsequences, interspecies homologs, and immunogenic fragments of the antigens that make up the fusion protein. Fusion proteins of the disclosure can also comprise additional copies of a component antigen or immunogenic fragment thereof. The fusion protein may contain one or more binding domains linked together and further linked to an Fc domain, such as an IgG Fc domain. Fusion proteins may be further linked together to mimic a monoclonal antibody and provide six or more binding domains. Fusion proteins may be produced by recombinant methods as is known in the art. Preparation of fusion proteins are known in the art and are described, e.g., in International Patent Application Publication Nos. WO 1995/027735 A1, WO 2005/103077 A1, WO 2008/025516 A1, WO 2009/007120 A1, WO 2010/003766 A1, WO 2010/010051 A1, WO 2010/078966 A1, U.S. Patent Application Publication Nos. US 2015/0125419 A1 and US 2016/0272695 A1, and U.S. Pat. No. 8,921,519, the disclosures of each of which are incorporated by reference herein.
The term “heterologous” when used with reference to portions of a nucleic acid or protein indicates that the nucleic acid or protein comprises two or more subsequences that are not found in the same relationship to each other in nature. For instance, the nucleic acid is typically recombinantly produced, having two or more sequences from unrelated genes arranged to make a new functional nucleic acid, e.g., a promoter from one source and a coding region from another source, or coding regions from different sources. Similarly, a heterologous protein indicates that the protein comprises two or more subsequences that are not found in the same relationship to each other in nature (e.g., a fusion protein).
The term “conservative amino acid substitutions” in means amino acid sequence modifications which do not abrogate the binding of an antibody or fusion protein to the antigen. Conservative amino acid substitutions include the substitution of an amino acid in one class by an amino acid of the same class, where a class is defined by common physicochemical amino acid side chain properties and high substitution frequencies in homologous proteins found in nature, as determined, for example, by a standard Dayhoff frequency exchange matrix or BLOSUM matrix. Six general classes of amino acid side chains have been categorized and include: Class I (Cys); Class II (Ser, Thr, Pro, Ala, Gly); Class III (Asn, Asp, Gln, Glu); Class IV (His, Arg, Lys); Class V (Ile, Leu, Val, Met); and Class VI (Phe, Tyr, Trp). For example, substitution of an Asp for another class III residue such as Asn, Gln, or Glu, is a conservative substitution. Thus, a predicted nonessential amino acid residue in an antibody is preferably replaced with another amino acid residue from the same class. Methods of identifying amino acid conservative substitutions which do not eliminate antigen binding are well-known in the art (see, e.g., Brummell, et al., Biochemistry 1993, 32, 1180-1187; Kobayashi, et al., Protein Eng. 1999, 12, 879-884 (1999); and Burks, et al., Proc. Natl. Acad. Sci. USA 1997, 94, 412-417.
The terms “sequence identity,” “percent identity,” and “sequence percent identity” (or synonyms thereof, e.g., “99% identical”) in the context of two or more nucleic acids or polypeptides, refer to two or more sequences or subsequences that are the same or have a specified percentage of nucleotides or amino acid residues that are the same, when compared and aligned (introducing gaps, if necessary) for maximum correspondence, not considering any conservative amino acid substitutions as part of the sequence identity. The percent identity can be measured using sequence comparison software or algorithms or by visual inspection. Various algorithms and software are known in the art that can be used to obtain alignments of amino acid or nucleotide sequences. Suitable programs to determine percent sequence identity include for example the BLAST suite of programs available from the U.S. Government's National Center for Biotechnology Information BLAST web site. Comparisons between two sequences can be carried using either the BLASTN or BLASTP algorithm. BLASTN is used to compare nucleic acid sequences, while BLASTP is used to compare amino acid sequences. ALIGN, ALIGN-2 (Genentech, South San Francisco, Calif.) or MegAlign, available from DNASTAR, are additional publicly available software programs that can be used to align sequences. One skilled in the art can determine appropriate parameters for maximal alignment by particular alignment software. In certain embodiments, the default parameters of the alignment software are used.
As used herein, the term “variant” encompasses but is not limited to antibodies or fusion proteins which comprise an amino acid sequence which differs from the amino acid sequence of a reference antibody by way of one or more substitutions, deletions and/or additions at certain positions within or adjacent to the amino acid sequence of the reference antibody. The variant may comprise one or more conservative substitutions in its amino acid sequence as compared to the amino acid sequence of a reference antibody. Conservative substitutions may involve, e.g., the substitution of similarly charged or uncharged amino acids. The variant retains the ability to specifically bind to the antigen of the reference antibody. The term variant also includes pegylated antibodies or proteins.
Nucleic acid sequences implicitly encompass conservatively modified variants thereof (e.g., degenerate codon substitutions) and complementary sequences, as well as the sequence explicitly indicated. Specifically, degenerate codon substitutions may be achieved by generating sequences in which the third position of one or more selected (or all) codons is substituted with mixed-base and/or deoxyinosine residues. Batzer, et al., Nucleic Acid Res. 1991, 19, 5081; Ohtsuka, et al., J. Biol. Chem. 1985, 260, 2605-2608; Rossolini, et al., Mol. Cell. Probes 1994, 8, 91-98. The term nucleic acid is used interchangeably with cDNA, mRNA, oligonucleotide, and polynucleotide.
The term “biosimilar” means a biological product, including a monoclonal antibody or protein, that is highly similar to a U.S. licensed reference biological product notwithstanding minor differences in clinically inactive components, and for which there are no clinically meaningful differences between the biological product and the reference product in terms of the safety, purity, and potency of the product. Furthermore, a similar biological or “biosimilar” medicine is a biological medicine that is similar to another biological medicine that has already been authorized for use by the European Medicines Agency. The term “biosimilar” is also used synonymously by other national and regional regulatory agencies. Biological products or biological medicines are medicines that are made by or derived from a biological source, such as a bacterium or yeast. They can consist of relatively small molecules such as human insulin or erythropoietin, or complex molecules such as monoclonal antibodies. For example, if the reference IL-2 protein is aldesleukin (PROLEUKIN), a protein approved by drug regulatory authorities with reference to aldesleukin is a “biosimilar to” aldesleukin or is a “biosimilar thereof” of aldesleukin. In Europe, a similar biological or “biosimilar” medicine is a biological medicine that is similar to another biological medicine that has already been authorized for use by the European Medicines Agency (EMA). The relevant legal basis for similar biological applications in Europe is Article 6 of Regulation (EC) No 726/2004 and Article 10(4) of Directive 2001/83/EC, as amended and therefore in Europe, the biosimilar may be authorized, approved for authorization or subject of an application for authorization under Article 6 of Regulation (EC) No 726/2004 and Article 10(4) of Directive 2001/83/EC. The already authorized original biological medicinal product may be referred to as a “reference medicinal product” in Europe. Some of the requirements for a product to be considered a biosimilar are outlined in the CHMP Guideline on Similar Biological Medicinal Products. In addition, product specific guidelines, including guidelines relating to monoclonal antibody biosimilars, are provided on a product-by-product basis by the EMA and published on its website. A biosimilar as described herein may be similar to the reference medicinal product by way of quality characteristics, biological activity, mechanism of action, safety profiles and/or efficacy. In addition, the biosimilar may be used or be intended for use to treat the same conditions as the reference medicinal product. Thus, a biosimilar as described herein may be deemed to have similar or highly similar quality characteristics to a reference medicinal product. Alternatively, or in addition, a biosimilar as described herein may be deemed to have similar or highly similar biological activity to a reference medicinal product. Alternatively, or in addition, a biosimilar as described herein may be deemed to have a similar or highly similar safety profile to a reference medicinal product. Alternatively, or in addition, a biosimilar as described herein may be deemed to have similar or highly similar efficacy to a reference medicinal product. As described herein, a biosimilar in Europe is compared to a reference medicinal product which has been authorized by the EMA. However, in some instances, the biosimilar may be compared to a biological medicinal product which has been authorized outside the European Economic Area (a non-EEA authorized “comparator”) in certain studies. Such studies include for example certain clinical and in vivo non-clinical studies. As used herein, the term “biosimilar” also relates to a biological medicinal product which has been or may be compared to a non-EEA authorized comparator. Certain biosimilars are proteins such as antibodies, antibody fragments (for example, antigen binding portions) and fusion proteins. A protein biosimilar may have an amino acid sequence that has minor modifications in the amino acid structure (including for example deletions, additions, and/or substitutions of amino acids) which do not significantly affect the function of the polypeptide. The biosimilar may comprise an amino acid sequence having a sequence identity of 97% or greater to the amino acid sequence of its reference medicinal product, e.g., 97%, 98%, 99%, or 100%. The biosimilar may comprise one or more post-translational modifications, for example, although not limited to, glycosylation, oxidation, deamidation, and/or truncation which is/are different to the post-translational modifications of the reference medicinal product, provided that the differences do not result in a change in safety and/or efficacy of the medicinal product. The biosimilar may have an identical or different glycosylation pattern to the reference medicinal product. Particularly, although not exclusively, the biosimilar may have a different glycosylation pattern if the differences address or are intended to address safety concerns associated with the reference medicinal product. Additionally, the biosimilar may deviate from the reference medicinal product in for example its strength, pharmaceutical form, formulation, excipients and/or presentation, providing safety and efficacy of the medicinal product is not compromised. The biosimilar may comprise differences in for example pharmacokinetic (PK) and/or pharmacodynamic (PD) profiles as compared to the reference medicinal product but is still deemed sufficiently similar to the reference medicinal product as to be authorized or considered suitable for authorization. In certain circumstances, the biosimilar exhibits different binding characteristics as compared to the reference medicinal product, wherein the different binding characteristics are considered by a Regulatory Authority such as the EMA not to be a barrier for authorization as a similar biological product. The term “biosimilar” is also used synonymously by other national and regional regulatory agencies.
The term “hematological malignancy” refers to mammalian cancers and tumors of the hematopoietic and lymphoid tissues, including but not limited to tissues of the blood, bone marrow, lymph nodes, and lymphatic system. Hematological malignancies are also referred to as “liquid tumors.” Hematological malignancies include, but are not limited to, acute lymphoblastic leukemia (ALL), chronic lymphocytic lymphoma (CLL), small lymphocytic lymphoma (SLL), acute myelogenous leukemia (AML), chronic myelogenous leukemia (CML), acute monocytic leukemia (AMoL), Hodgkin's lymphoma, and non-Hodgkin's lymphomas. The term “B cell hematological malignancy” refers to hematological malignancies that affect B cells.
The term “solid tumor” refers to an abnormal mass of tissue that usually does not contain cysts or liquid areas. Solid tumors may be benign or malignant. The term “solid tumor cancer” refers to malignant, neoplastic, or cancerous solid tumors. Solid tumor cancers include, but are not limited to, sarcomas, carcinomas, and lymphomas, such as cancers of the lung, breast, prostate, colon, rectum, and bladder. The tissue structure of solid tumors 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.
The term “microenvironment,” as used herein, may refer to the solid or hematological tumor microenvironment as a whole or to an individual subset of cells within the microenvironment. The tumor microenvironment, as used herein, refers to a complex mixture of “cells, soluble factors, signaling molecules, extracellular matrices, and mechanical cues that promote neoplastic transformation, support tumor growth and invasion, protect the tumor from host immunity, foster therapeutic resistance, and provide niches for dominant metastases to thrive,” as described in Swartz, et al., Cancer Res., 2012, 72, 2473. Although tumors express antigens that should be recognized by T cells, tumor clearance by the immune system is rare because of immune suppression by the microenvironment.
The term “effective amount” or “therapeutically effective amount” refers to that amount of a compound or combination of compounds as described herein that is sufficient to effect the intended application including, but not limited to, disease treatment. A therapeutically effective amount may vary depending upon the intended application (in vitro or in vivo), or the subject and disease condition being treated (e.g., the weight, age and gender of the subject), the severity of the disease condition, or the manner of administration. The term also applies to a dose that will induce a particular response in target cells (e.g., the reduction of platelet adhesion and/or cell migration). The specific dose will vary depending on the particular compounds chosen, the dosing regimen to be followed, whether the compound is administered in combination with other compounds, timing of administration, the tissue to which it is administered, and the physical delivery system in which the compound is carried.
A “therapeutic effect” as that term is used herein, encompasses a therapeutic benefit and/or a prophylactic benefit. A prophylactic effect includes delaying or eliminating the appearance of a disease or condition, delaying or eliminating the onset of symptoms of a disease or condition, slowing, halting, or reversing the progression of a disease or condition, or any combination thereof.
The terms “QD,” “qd,” or “q.d.” mean quaque die, once a day, or once daily. The terms “BID,” “bid,” or “b.i.d.” mean bis in die, twice a day, or twice daily. The terms “TID,” “tid,” or “t.i.d.” mean ter in die, three times a day, or three times daily. The terms “QID,” “qid,” or “q.i.d.” mean quater in die, four times a day, or four times daily.

As described herein, providing a population of TILs to a target entity having a condition, can lead to a discernable effect on the condition, provided that the target entity has a first property. Determining whether such target entity does in fact possess such property can be of interest for determining whether providing the population of TILs to the target entity is warranted or not, because the lack of the first property would indicate that it is not. In order to determine whether such first property is present, the target entity can be classified into a time-to-event class. In some embodiments, a time-to-event class is associated with a certain likelihood that the target entity has the first property.
In some embodiments, the target entity can be a patient having cancer, for example a mammal, or more specifically a human. In some embodiments, the condition associated with the target entity is a disease or disorder, for example cancer. In some embodiments, the first property is the ability of the target entity to respond in a certain way to administration of T cells, for example by exhibiting a discernable effect on its condition. In some embodiments, the T cells include tumor infiltrating lymphocytes (TILs). In some embodiments, the T cells include natural killer T cells. In some embodiments, the T cells include T helper cells. In some embodiments, the T cells include cytotoxic T cells. In some embodiments, the T cells include gamma delta T cells. In some embodiments, the T cells include allogeneic T cells. In some embodiments, the T cells include autologous T cells. In some embodiments, the first property is the ability of the target entity to respond in a certain way to administration of TILs, for example by exhibiting a discernable effect on its condition. In some embodiments, the discernable effect on the condition is remission of the condition, for example remission of cancer, such as complete remission or partial remission, or lack of progression of the condition for a period of time, for example lack of cancer progression. In some embodiments, the event is a change in the status of the target entity, for example renewed progression of the condition. In some embodiments, the discernable effect is a complete response, a partial response, no response, stable disease, or progressive disease.
The first property of the target entity can be determined from samples of the target entity, for example biological samples from a human. In some embodiments, the first property of the target can be determined by comparing a sample of the target entity with samples of other entities which have been provided T cells in the past, and on which entities a discernable effect of providing T cells, or lack thereof, is known. In some embodiments, the T cells include tumor infiltrating lymphocytes (TILs). In some embodiments, the T cells include natural killer T cells. In some embodiments, the T cells include T helper cells. In some embodiments, the T cells include cytotoxic T cells. In some embodiments, the T cells include gamma delta T cells. In some embodiments, the T cells include allogeneic T cells. In some embodiments, the T cells include autologous T cells. In some embodiments, the first property of the target can be determined by comparing a sample of the target entity with samples of other entities which have been provided TILs in the past, and on which entities a discernable effect of providing TILs, or lack thereof, is known. The samples of these other entities can be used to build time-to-event classes. In some embodiments, the samples of these other entities were collected prior to the providing of TILs. In some embodiments, the other entities had conditions such as metastatic melanoma.
In some embodiments, the samples of both the target entity, and the samples of the other entities, are used to generate an analytical signature prior to comparison. In some embodiments, the analytical signature comprises one or more features. In some embodiments, the analytical signature is derived from electrophoresis or chromatography data. As described herein, in some embodiments, the analytical signature is derived from mass spectra data. In some embodiments, the mass spectra data is derived from MALDI mass spectra, for example MALDI-TOF data. In some embodiments, the analytical signature includes selected m/z values from the mass spectra data. Through various mass spectra processing techniques described herein, the one or more features of the analytical signature are derived from the mass spectra data. In some embodiments, the features manifest themselves in specific m/z regions of the spectra where spectral peaks change in intensity and shape. In some embodiments, such features are defined by certain m/z ranges. In some embodiments, the m/z ranges comprise an m/z range left limit. In some embodiments, the m/z ranges comprise an m/z range center. In some embodiments, the m/z ranges comprise an m/z range right limit. In some embodiments, the feature is assigned a value. In some embodiments, the feature value for a specific spectrum is the area under the spectrum within the m/z span of the feature definition. In some embodiments, the feature definition is according to the ranges described in Table 16.

Now that details of a system 48 for screening a target entity to determine whether it has a first property have been disclosed, details regarding aspects of methods for screening a target entity to determine whether it has a first property are disclosed below.
In some embodiments, device 104 is a mass spectrometer. In some embodiments the analytical signature 210 of a reference entity 210, the analytical signature 216 of a test entity 214, and/or the analytical signature 302 or 306 of a target entity is acquired using a mass spectrometer. In some embodiments the analytical signature 210 of a reference entity 210, the analytical signature 216 of a test entity 214, and/or the analytical signature 302 or 306 of a target entity is acquired using a mass spectrometer conducted in positive ion mode. In some embodiments, the analytical signature 210 of a reference entity 210, the analytical signature 216 of a test entity 214, and/or the analytical signature 302 or 306 of a target entity is determined using Deep-MALDI TOF mass spectrometry.
Deep-MALDI (matrix assisted laser desorption ionization) refers to methods of analyzing biological samples, for example serum or other blood-based samples, using a MALDI-TOF (time of flight) mass spectrometer instrument. The method is described in more detail in U.S. Pat. No. 9,279,798, incorporated herein in its entirety. The method includes the steps of applying the sample to a sample spot on a MALDI-TOF sample plate and directing a large number of laser shots, e.g., more than 20,000, at the sample spot, and collecting mass-spectral data. Any number of laser shots can be used, for example at least 50,000, at least 75,000, at least 100,000, at least 200,000, or at least 500,000 shots are directed onto the sample. Employing a large number of laser shots leads to a reduction in the noise level in the resulting mass spectra, and a significant amount of additional spectral information can be obtained from the sample as compared to traditional MALDI techniques. Furthermore, peaks visible at lower number of shots are better defined and allow for more reliable comparisons between different samples.
In traditional MALDI techniques it is typically difficult to obtain more than 20,000 shots from a single MALDI spot. For example, one issue with using many hundreds of thousands of shots from a MALDI sample spot is that in common spot preparation only some shot locations within a spot yield sufficient ion current to contribute substantially to the signal in a combined spectrum. In deep-MALDI however, specific procedures such as automated raster scanning affords the capability of performing vastly more shots on a single spot than in traditional MALDI techniques. Manual processes to visually select high ion yield locations within a given spot on a MALDI plate for laser shots can be used, but automation of the process to select locations for laser shots is also possible, and preferred for a high throughput implementation. Improving the quality of MALDI spots in such a way that most randomly selected locations yield a high ion current is also an approach that can be used.
Automation of the acquisition may include defining optimal movement patterns of the laser scanning of the spot in a raster fashion, and generation of a specified sequence for multiple raster scans at discrete X/Y coordinate locations within a spot to result in a multitude of shots, e.g., 750,000, 1,000,000, 2,000,000, or 3,000,000 shots from one or more spots. Spectra acquired from 250,000 shots per each of several sample spots can be combined into a 1,000,000 shot spectrum. Hundreds of thousands of shots to millions of shots collected on multiple spots containing the same sample can be averaged together to create one spectrum. Further methods of automation include generation of raster files for non-contiguous X/Y raster scanning of a sample spot, dividing the spot into a grid of sub-spots (e.g., a 3×3 or 5×5 grid), and generating raster files for raster scanning at discrete X/Y coordinate locations of the sub-spots, and using image analysis techniques to identify areas of interest containing relatively high concentrations of sample material for spectral acquisition (multiple shots) and/or those areas where the protein concentration is relatively low, and performing spectral acquisition in the areas with relatively high protein concentration.
Another deep-MALDI technique relates to optimizing the process of sample application to the MALDI plate (“spotting”) to produce uniform, homogeneous crystals of the sample/matrix within a single spot. This process facilitates obtaining hundreds of thousands of shots from a single spot on the MALDI plate using automated methods.
Deep-MALDI has many applications, including biomarker discovery, test development, substance testing, validation of existing tests, and hypothesis generation, e.g., in biomarker discovery efforts. Deep-MALDI also enhances the potential of “dilute and shoot” methods in mass spectrometry research by its ability to reproducibly quantify the amount of many more proteins in a complex sample in a high throughput fashion, as compared to traditional techniques.
The Diagnostic Cortex refers to methods and systems for classifier generation including obtaining data for classification of a multitude of samples, the data for each of the samples consisting of a multitude of physical measurement feature values and a class label. The methods and their application are described in more detail in U.S. Pat. Nos. 7,736,905, 8,914,238, 8,718,996, 7,858,389, 7,858,390, and 9,477,906, and U.S. Patent Application Publications No. 2011/0208433, and 2013/0344111, incorporated herein in their entireties. Individual mini-classifiers are generated using sets of features from the samples. The performance of the mini-classifiers is tested, and those that meet a performance threshold are retained. A master classifier is then generated by conducting a regularized ensemble training of the retained/filtered set of mini-classifiers to the classification labels for the samples, e.g., by randomly selecting a small fraction of the filtered mini-classifiers (drop out regularization) and conducting logistical training on such selected mini-classifiers. The set of samples are randomly separated into a test set and a training set. The steps of generating the mini-classifiers, filtering and generating a master classifier are repeated for different realizations of the separation of the set of samples into test and training sets, thereby generating a plurality of master classifiers. A final classifier is defined from one or a combination of more than one of the master classifiers.
In contrast to standard applications of machine learning focusing on developing classifiers when large training data sets are available, i.e., the big data challenge, in bio-life-sciences the problem setting is different. Typically, the problem is that the number (n) of available samples, arising typically from clinical studies, is often limited, and the number of attributes (measurements) (p) per sample usually exceeds the number of samples. Rather than obtaining information from many instances, in these deep data problems one attempts to gain information from a deep description of individual instances. The methods involved in the Diagnostic Cortex take advantage of this insight, and are particularly useful in problems where p>>n.
Methods for generating a classifier include a step of obtaining physical measurement data for classification from a plurality of samples (e.g., blood, tissue, or other type of biological sample). The data for classification for each of the samples consists of a multitude of feature values (e.g., integrated intensity values at particular m/Z ranges in mass spectrometry data, fluorescence intensity measurements associated with mRNA transcript, protein, or gene expression levels) and an associated class or group label. The class or group label can take various forms, and it can be iteratively defined in generation of the classifier, and in some embodiments may have some diagnostic or therapeutic meaning or attribute. Further steps include constructing a multitude of individual mini-classifiers using sets of feature values from the samples up to a pre-selected feature set size (s, integer). For example, mini-classifiers are constructed for individual features (s=1) and/or pairs of features (s=2). For example, if the initial feature set contains 100 features, the number of mini-classifiers for s=1 would be 100, and for s=2 would be 4950=100*99/2. The mini-classifiers execute a classification algorithm, such as k-nearest neighbors, in which the values for a feature or pairs of features of a sample instance are compared to the values of the same feature or features in a training set and the nearest neighbors (e.g., k=5) in feature space are identified and by majority vote a class label is assigned to the sample instance by each mini-classifier. Other supervised classification methods could be used as an alternative to k-nearest neighbors, e.g., tree-based classification, linear discriminants, support vector machines, etc. It will be understood that one could use larger values of s, and the number of possible feature combinations would increase resulting in larger computational resource requirements. Further steps include testing the performance of individual mini-classifiers to classify at least some of the multitude of biological samples (e.g., a training set, a subset of an entire development set), and retaining only those mini-classifiers whose classification accuracy or predictive power, or any suitable other performance metric, exceeds a pre-defined threshold, to thereby arrive at a filtered (pruned) set of mini-classifiers. Other steps include generating a master classifier by combining the filtered mini-classifiers using a regularized combination method. This regularized combination method can take, in some embodiments, the form of repeatedly conducting a logistic training of the filtered set of mini-classifiers to the class labels for the samples, which can be done by randomly selecting a small fraction of the filtered mini-classifiers as a result of carrying out an extreme dropout from the filtered set of mini-classifiers (a technique referred to as drop-out regularization), and conducting logistical training on such selected mini-classifiers. Further steps include randomly separating the samples into a test set and a training set, and repeating the previous steps in a programmed computer for different realizations of the separation of the set of samples into test and training sets, thereby generating a plurality of master classifiers, one for each realization of the separation of the set of samples into training and test sets. The methods also include defining a final classifier from one or a combination of more than one of the plurality of master classifiers, final classifier which can be defined in a variety of ways, including by selection of a single master classifier from the plurality of master classifiers having typical or representative performance, by majority vote of all the master classifiers, by modified majority vote, by weighted majority vote, or otherwise.

In an embodiment, REP can be performed in a gas permeable container by any suitable method. For example, T cells or TILs can be rapidly expanded using non-specific T cell receptor stimulation in the presence of interleukin-2 (IL-2) or interleukin-15 (IL-15). The non-specific T cell receptor stimulus can include, for example, about 30 ng/mL of OKT-3, a monoclonal anti-CD3 antibody (commercially available from Ortho-McNeil, Raritan, N.J. or Miltenyi Biotech, Auburn, Calif.). T cells or TILs can be rapidly expanded by further stimulation of the T cells or TILs in vitro with one or more antigens, including antigenic portions thereof, such as epitope(s), of the cancer, which can be optionally expressed from a vector, such as a human leukocyte antigen A2 (HLA-A2) binding peptide, e.g., 0.3 μM MART-1:26-35 (27 L) or gpl 00:209-217 (210M), optionally in the presence of a T-cell growth factor, such as 300 IU/mL IL-2 or IL-15. Other suitable antigens may include, e.g., NY-ESO-1, TRP-1, TRP-2, tyrosinase cancer antigen, MAGE-A3, SSX-2, and VEGFR2, or antigenic portions thereof. T cells or TILs may also be rapidly expanded by re-stimulation with the same antigen(s) of the cancer pulsed onto HLA-A2-expressing antigen-presenting cells. Alternatively, the T cells or TILs can be further re-stimulated with, e.g., example, irradiated, autologous lymphocytes or with irradiated HLA-A2+ allogeneic lymphocytes and IL-2. In some embodiments, the T cells include tumor infiltrating lymphocytes (TILs). In some embodiments, the T cells include natural killer T cells. In some embodiments, the T cells include T helper cells. In some embodiments, the T cells include cytotoxic T cells. In some embodiments, the T cells include gamma delta T cells. In some embodiments, the T cells include allogeneic T cells. In some embodiments, the T cells include autologous T cells.
In an embodiment, a method for expanding T cells or TILs may include using about 5000 mL to about 25000 mL of cell culture medium, about 5000 mL to about 10000 mL of cell culture medium, or about 5800 mL to about 8700 mL of cell culture medium. In an embodiment, a method for expanding T cells or TILs may include using about 1000 mL to about 2000 mL of cell medium, about 2000 mL to about 3000 mL of cell culture medium, about 3000 mL to about 4000 mL of cell culture medium, about 4000 mL to about 5000 mL of cell culture medium, about 5000 mL to about 6000 mL of cell culture medium, about 6000 mL to about 7000 mL of cell culture medium, about 7000 mL to about 8000 mL of cell culture medium, about 8000 mL to about 9000 mL of cell culture medium, about 9000 mL to about 10000 mL of cell culture medium, about 10000 mL to about 15000 mL of cell culture medium, about 15000 mL to about 20000 mL of cell culture medium, or about 20000 mL to about 25000 mL of cell culture medium. In an embodiment, expanding the number of T cells or TILs uses no more than one type of cell culture medium. Any suitable cell culture medium may be used, e.g., AIM-V cell medium (L-glutamine, 50 μM streptomycin sulfate, and 10 μM gentamicin sulfate) cell culture medium (Invitrogen, Carlsbad Calif.). In this regard, the inventive methods advantageously reduce the amount of medium and the number of types of medium required to expand the number of T cells or TILs. In an embodiment, expanding the number of T cells or TILs may comprise feeding the cells no more frequently than every third or fourth day. Expanding the number of cells in a gas permeable container simplifies the procedures necessary to expand the number of cells by reducing the feeding frequency necessary to expand the cells. In some embodiments, the T cells include tumor infiltrating lymphocytes (TILs). In some embodiments, the T cells include natural killer T cells. In some embodiments, the T cells include T helper cells. In some embodiments, the T cells include cytotoxic T cells. In some embodiments, the T cells include gamma delta T cells. In some embodiments, the T cells include allogeneic T cells. In some embodiments, the T cells include autologous T cells.
In an embodiment, the rapid expansion is performed using a gas permeable container. Such embodiments allow for cell populations to expand from about 5×105 cells/cm2 to between 10×106 and 30×106 cells/cm2. In an embodiment, this expansion occurs without feeding. In an embodiment, this expansion occurs without feeding so long as medium resides at a height of about 10 cm in a gas-permeable flask. In an embodiment this is without feeding but with the addition of one or more cytokines. In an embodiment, the cytokine can be added as a bolus without any need to mix the cytokine with the medium.

After incubation for 30 minutes at 37° C. in 5% CO2, the tumor or portion thereof may be mechanically disrupted a third time for approximately 1 minute. If after the third mechanical disruption, large pieces of tissue are present, 1 or 2 additional mechanical dissociations may be applied to the sample, with or without 30 additional minutes of incubation at 37° C. in 5% CO2. At the end of the final incubation, if the cell suspension contains a large number of red blood cells or dead cells, a density gradient separation using Ficoll may be performed to remove these cells. TIL cultures were initiated in 24-well plates (Costar 24-well cell culture cluster, flat bottom; Corning Incorporated, Corning, N.Y.), each well may be seeded with 1×106 tumor digest cells or one tumor fragment approximately 1 to 8 mm3 in size in 2 mL of complete medium (CM) with IL-2 (6000 IU/mL; Chiron Corp., Emeryville, Calif.). CM comprises Roswell Park Memorial Institute (RPMI) 1640 buffer with GlutaMAX, supplemented with 10% human AB serum, 25 mM Hepes, and 10 mg/mL gentamicin. Cultures may be initiated in gas-permeable flasks with a 40 mL capacity and a 10 cm2 gas-permeable silicon bottom (G-Rex 10; Wilson Wolf Manufacturing, New Brighton, each flask may be loaded with 10-40×106 viable tumor digest cells or 5-30 tumor fragments in 10-40 mL of CM with IL-2. G-Rex 10 and 24-well plates may be incubated in a humidified incubator at 37° C. in 5% CO2 and 5 days after culture initiation, half the media may be removed and replaced with fresh CM and IL-2 and after day 5, half the media may be changed every 2-3 days. Rapid expansion protocol (REP) of TILs may be performed using T-175 flasks and gas-permeable bags or gas-permeable G-Rex flasks, as described elsewhere herein. For REP in T-175 flasks, 1×106 TILs may be suspended in 150 mL of media in each flask. The TIL may be cultured in a 1 to 1 mixture of CM and AIM-V medium (50/50 medium), supplemented with 3000 IU/mL of IL-2 and 30 ng/mL of anti-CD3 antibody (OKT-3). The T-175 flasks may be incubated at 37° C. in 5% CO2. Half the media may be changed on day 5 using 50/50 medium with 3000 IU/mL of IL-2. On day 7, cells from 2 T-175 flasks may be combined in a 3 L bag and 300 mL of AIM-V with 5% human AB serum and 3000 IU/mL of IL-2 may be added to the 300 mL of TIL suspension. The number of cells in each bag may be counted every day or two days, and fresh media may be added to keep the cell count between 0.5 and 2.0×106 cells/mL. For REP in 500 mL capacity flasks with 100 cm2 gas-permeable silicon bottoms (e.g., G-Rex 100, Wilson Wolf Manufacturing, as described elsewhere herein), 5×106 or 10×106 TILs may be cultured in 400 mL of 50/50 medium, supplemented with 3000 IU/mL of IL-2 and 30 ng/mL of anti-CD3 antibody (OKT-3). The G-Rex100 flasks may be incubated at 37° C. in 5% CO2. On day five, 250 mL of supernatant may be removed and placed into centrifuge bottles and centrifuged at 1500 rpm (491 g) for 10 minutes. The obtained TIL pellets may be resuspended with 150 mL of fresh 50/50 medium with 3000 IU/mL of IL-2 and added back to the G-Rex 100 flasks. When TIL are expanded serially in G-Rex 100 flasks, on day seven the TIL in each G-Rex100 are suspended in the 300 mL of media present in each flask and the cell suspension may be divided into three 100 mL aliquots that may be used to seed 3 G-Rex100 flasks. About 150 mL of AIM-V with 5% human AB serum and 3000 IU/mL of IL-2 may then be added to each flask. G-Rex 100 flasks may then be incubated at 37° C. in 5% CO2, and after four days, 150 mL of AIM-V with 3000 IU/mL of IL-2 may be added to each G-Rex 100 flask. After this, the REP may be completed by harvesting cells on day 14 of culture. In some embodiments, the method can be used to expand any T cell.

In an embodiment, a method of expanding or treating a cancer includes a step wherein T cells or TILs are obtained from a patient tumor sample. A patient tumor sample may be obtained using methods known in the art. For example, T cells or TILs may be cultured from enzymatic tumor digests and tumor fragments (about 1 to about 8 mm3 in size) from sharp dissection. Such tumor digests may be produced by incubation in enzymatic media (e.g., Roswell Park Memorial Institute (RPMI) 1640 buffer, 2 mM glutamate, 10 mcg/mL gentamicine, 30 units/mL of DNase and 1.0 mg/mL of collagenase) followed by mechanical dissociation (e.g., using a tissue dissociator). Tumor digests may be produced by placing the tumor in enzymatic media and mechanically dissociating the tumor for approximately 1 minute, followed by incubation for 30 minutes at 37° C. in 5% CO2, followed by repeated cycles of mechanical dissociation and incubation under the foregoing conditions until only small tissue pieces are present. At the end of this process, if the cell suspension contains a large number of red blood cells or dead cells, a density gradient separation using FICOLL branched hydrophilic polysaccharide may be performed to remove these cells. Alternative methods known in the art may be used, such as those described in U.S. Patent Application Publication No. 2012/0244133 A1, the disclosure of which is incorporated by reference herein. Any of the foregoing methods may be used in any of the embodiments described herein for methods of expanding T cells or TILs or methods treating a cancer.

The T-175 flasks may be incubated at 37° C. in 5% CO2. Half the media may be exchanged on day 5 using 50/50 medium with 3000 IU per mL of IL-2. On day 7 cells from two T-175 flasks may be combined in a 3 L bag and 300 mL of AIM V with 5% human AB serum and 3000 IU per mL of IL-2 was added to the 300 ml of TIL suspension. The number of cells in each bag was counted every day or two and fresh media was added to keep the cell count between 0.5 and 2.0×106 cells/mL.

Non-Myeloablative Lymphodepletion with Chemotherapy
In an embodiment, the invention provides a method of treating a cancer with a population of T cells or TILs, wherein a patient is pre-treated with non-myeloablative chemotherapy prior to an infusion of T cells or TILs. In an embodiment, the non-myeloablative chemotherapy is one or more chemotherapeutic agents. In an embodiment, the non-myeloablative chemotherapy is cyclophosphamide 60 mg/kg/d for 2 days (days 27 and 26 prior to T cells or TILs infusion) and fludarabine 25 mg/m2/d for 5 days (days 27 to 23 prior to TIL infusion). In an embodiment, after non-myeloablative chemotherapy and T cells or TILs infusion (at day 0) according to the present disclosure, the patient receives an intravenous infusion of IL-2 intravenously at 720,000 IU/kg every 8 hours to physiologic tolerance. In some embodiments, the T cells include tumor infiltrating lymphocytes (TILs). In some embodiments, the T cells include natural killer T cells. In some embodiments, the T cells include T helper cells. In some embodiments, the T cells include cytotoxic T cells. In some embodiments, the T cells include gamma delta T cells. In some embodiments, the T cells include allogeneic T cells. In some embodiments, the T cells include autologous T cells.
Experimental findings indicate that lymphodepletion prior to adoptive transfer of tumor-specific T lymphocytes plays a key role in enhancing treatment efficacy by eliminating regulatory T cells and competing elements of the immune system (“cytokine sinks”). Accordingly, some embodiments of the invention utilize a lymphodepletion step (sometimes also referred to as “immunosuppressive conditioning”) on the patient prior to the introduction of the T cells or TILs of the invention.
In general, lymphodepletion is achieved using administration of fludarabine or cyclophosphamide (the active form being referred to as mafosfamide) and combinations thereof. Such methods are described in Gassner, et al., Cancer Immunol. Immunother. 2011, 60, 75-85, Muranski, et al., Nat. Clin. Pract. Oncol., 2006, 3, 668-681, Dudley, et al., J. Clin. Oncol. 2008, 26, 5233-5239, and Dudley, et al., J. Clin. Oncol. 2005, 23, 2346-2357, all of which are incorporated by reference herein in their entireties.
In some embodiments, the fludarabine is administered at a concentration of 0.5 μg/mL-10 μg/mL fludarabine. In some embodiments, the fludarabine is administered at a concentration of 1 μg/mL fludarabine. In some embodiments, the fludarabine treatment is administered for 1 day, 2 days, 3 days, 4 days, 5 days, 6 days, or 7 days or more. In some embodiments, the fludarabine is administered at a dosage of 10 mg/kg/day, 15 mg/kg/day, 20 mg/kg/day, 25 mg/kg/day, 30 mg/kg/day, 35 mg/kg/day, 40 mg/kg/day, or 45 mg/kg/day. In some embodiments, the fludarabine treatment is administered for 2-7 days at 35 mg/kg/day. In some embodiments, the fludarabine treatment is administered for 4-5 days at 35 mg/kg/day. In some embodiments, the fludarabine treatment is administered for 4-5 days at 25 mg/kg/day.
In some embodiments, the mafosfamide, the active form of cyclophosphamide, is obtained at a concentration of 0.5 μg/mL-10 μg/mL by administration of cyclophosphamide. In some embodiments, mafosfamide, the active form of cyclophosphamide, is obtained at a concentration of 1 μg/mL by administration of cyclophosphamide. In some embodiments, the cyclophosphamide treatment is administered for 1 day, 2 days, 3 days, 4 days, 5 days, 6 days, or 7 days or more. In some embodiments, the cyclophosphamide is administered at a dosage of 100 mg/m2/day, 150 mg/m2/day, 175 mg/m2/day 200 mg/m2/day, 225 mg/m2/day, 250 mg/m2/day, 275 mg/m2/day, or 300 mg/m2/day. In some embodiments, the cyclophosphamide is administered intravenously (i.e., i.v.) In some embodiments, the cyclophosphamide treatment is administered for 2-7 days at 35 mg/kg/day. In some embodiments, the cyclophosphamide treatment is administered for 4-5 days at 250 mg/m2/day i.v. In some embodiments, the cyclophosphamide treatment is administered for 4 days at 250 mg/m2/day i.v.
In some embodiments, lymphodepletion is performed by administering the fludarabine and the cyclophosphamide are together to a patient. In some embodiments, fludarabine is administered at 25 mg/m2/day i.v. and cyclophosphamide is administered at 250 mg/m2/day i.v. over 4 days.
In an embodiment, the lymphodepletion is performed by administration of cyclophosphamide at a dose of 60 mg/m2/day for two days followed by administration of fludarabine at a dose of 25 mg/m2/day for five days.
The embodiments encompassed herein are now described with reference to the following examples. These examples are provided for the purpose of illustration only and the disclosure encompassed herein should in no way be construed as being limited to these examples, but rather should be construed to encompass any and all variations which become evident as a result of the teachings provided herein.
Adoptive cell transfer therapy can lead to durable complete regressions in patients with metastatic melanoma (Goff et al., J Clin Oncol, 2016, Jul. 10, 34(20):2389), but only in a minority of treated patients. It is of interest to be able to identify patients most likely or very unlikely to respond to such therapy to provide an enhanced durable response rate within a selected patient population.
Pretreatment serum samples collected from patients with metastatic melanoma in a prospective study of adoptive transfer of tumor-infiltrating lymphocytes following different intensities of lymphodepletion were provided. Two Biodesix immunotherapy tests were performed on the samples, respectively referred to herein as the BDX008 test and the IL2 test, and a new classifier development was carried out with the aim of creating a new test able to identify patients most likely to have durable benefit from therapy. The BDX008 test classifies samples as BDX008− or BDX008+. BDX008+ is more generally associated with longer periods of progression free survival than BDX008−. The IL2 test classifies samples as IL2 test Early (worse prognosis group) or IL2 test Late (better prognosis group). In other words IL2 test late is more generally associated with longer periods of progression free survival than IL2 test early.
Samples: the sample manifest included 90 samples. One sample (NV12_SP_2108_002) was missing and four samples were found to be hemolyzed on visual inspection (HARV_SP_0612_001, HARV_SP_0657_002, NV12_SP_0706_001, and NV12_SP_2186001). The remaining 85 samples were prepared for spectral acquisition and deep MALDI spectra acquired. The baseline clinical characteristics of the cohort of 85 patients with samples available for analysis are summarized in Table 1 including the baseline clinical characteristics of the analysis cohort of the 85 patients.
Response to therapy for the cohort is summarized in Table 2 and progression-free survival (PFS) is shown in
The BDX008 test was applied to the 85 samples suitable for mass spectral acquisition. Twenty-nine (34%) were classified as BDX008− and 56 (66%) as BDX008+. BDX008 classifications by sample are given in Table 3 (existing test classifications and batch allocations; batch in which mass spectra were collected, BDX008, and IL2 test classification by sample).
The IL2 test was applied to the 85 samples suitable for mass spectral acquisition. Fifty-nine (69%) were classified as IL2 test Early (worse prognosis group) and 26 (31%) as IL2 test Late (better prognosis group). IL2 test classifications by sample are given in Table 3.
Samples were thawed and 3 μL aliquots of each sample and quality control serum (a pooled sample obtained from serum of five healthy patients, purchased from ProMedDx, “SerumP3”) spotted onto VeriStrat® serum cards (Therapak). The cards were allowed to dry for 1 hour at ambient temperature after which the whole serum spot was punched out with a 6 mm skin biopsy punch (Acuderm). Each punch was placed in a centrifugal filter with 0.45 μm nylon membrane (VWR). One hundred μL of HPLC grade water (JT Baker) was added to the centrifugal filter containing the punch. The punches were vortexed gently for 10 minutes, then spun down at 14,000 rcf for two minutes. The flow-through was removed and transferred back on to the punch for a second round of extraction. For the second round of extraction, the punches were vortexed gently for three minutes, then spun down at 14,000 rcf for two minutes. Twenty microliters of the filtrate from each sample was then transferred to a 0.5 mL Eppendorf tube for MALDI analysis.
All subsequent sample preparation steps were carried out in a custom designed humidity and temperature control chamber (Coy Laboratory). The temperature was set to 30° C. and the relative humidity at 10%.
An equal volume of freshly prepared matrix (25 mg of sinapinic acid per 1 mL of 50% acetonitrile: 50% water plus 0.1% TFA) was added to each 20 μL serum extract and the mix vortexed for 30 sec. The first three aliquots (3×2 μL) of sample:matrix mix were discarded into the tube cap. Eight aliquots of 2 μL sample:matrix mix were then spotted onto a stainless steel MALDI target plate (SimulTOF). The MALDI target was allowed to dry in the chamber before placement in the MALDI mass spectrometer.
This set of samples was processed for MALDI analysis in two batches. QC samples were added to the beginning (two preparations) and end (two preparations) of each batch run. The distribution of the samples run by batch is shown in Table 3.
The entire sample preparation and spectral acquisition process was repeated twice for all 85 samples suitable for generation of mass spectra, with a mass spectrometer qualification run before the first run, between the first run and the second run, and immediately following the second run. Samples were randomized separately for batch and MALDI plate spot for each run.
Mass Spectrometer Qualification: The instrument qualification procedure was conducted before and after acquiring spectra from the samples, ensuring expected performance was maintained throughout data collection on the mass spectrometry for the project. The procedure is defined below.
Sample set: the RuO40 sample set is composed of 40 human serum samples that are well characterized. A ‘gold standard’ or baseline run was acquired on the ST100 mass spectrometer using the deep MALDI sample preparation and acquisition procedure. The data were processed using an established processing method, independent of any ‘test’, and a feature table of expected values was generated for 90 mass spectral features that were selected to cover the m/z range of interest and cover the range of feature intensities.
Concordance analysis: to assess instrument performance, the concordance analysis is performed on the RuO40 sample set. In brief, the samples are prepared and spectra acquired. The data is then processed using the established processing methods, including background subtraction, normalization, alignment, and batch correction (to the gold standard) to arrive at a table of feature values. These 90 features are compared to the values that were collected in the gold standard run. Concordance plots are generated and linear regressions are performed for all 90 features. The slopes are used to compute a summary statistic (essentially a sum of residuals squared). To pass the concordance analysis the summary statistic must meet the requirements of an established metric (summary statistic >0.96). In addition, the spectra must pass all quality control measures that are included in the processing as a prerequisite to the concordance analysis.
Instrument Qualification Metrics for All Qualification Runs: as summarized in Table 8 and Table 9.
MALDI spectra were obtained using a MALDI-TOF mass spectrometer (SimulTOF 100 s/n: LinearBipolar 11.1024.01 from Virgin Instruments, Marlborough, Mass., USA). The instrument was set to operate in positive ion mode, with ions generated using a 349 nm, diode-pumped, frequency-tripled Nd:YLF laser operated at a laser repetition rate of 0.5 kHz. Immediately prior to each run of the test samples, the mass spectrometer underwent and passed machine qualification procedures to verify adequate mass spectrometer performance (see Table 8 and Table 9). External calibration was performed using the following peaks in the QC serum spectra: m/z=3317 Da, 4155 Da, 6635 Da, 9430 Da, 13888 Da, 15876 Da, and 28098 Da. After the second run of the test samples, the mass spectrometer again underwent and passed machine qualification.
Spectra from each MALDI spot were collected as 800 shot spectra that were ‘hardware averaged’ as the laser fires continuously across the spot while the stage is moving at a speed of 0.25 mm/sec. A minimum intensity threshold of 0.01 V was used to discard any ‘flat line’ spectra. All 800 shot spectra with intensity above this threshold were acquired without any further processing.
For the new classifier development, spectral processing parameters were defined specifically.
Raster Spectral Processing—Alignment and filtering: all raster spectra of 800 shots were processed through an alignment workflow to align prominent peaks in the spectra to a set of 43 alignment points (see Table 10). A filter was applied that smooths noise and background was subtracted for peak identification. Given the identified peaks, the filtered spectra (without background subtraction) were aligned. Additional filtering parameters required that raster spectra have at least 20 peaks and used at least 5 alignment points to be included in the pool of rasters used to assemble the average spectrum.
Raster Averaging: averages were created from the pool of aligned and filtered raster spectra. A random selection of 500 raster spectra was averaged to create a final analysis spectrum for each sample of 400,000 shots.
Load range: although spectra are typically collected in the m/z range of 3-75 kDa, the range for spectral processing, including feature generation, is limited to 3-30 kDa, as features above 30 kDa have poor resolution and have been found not to be reproducible at a feature value level.
Background estimation and subtraction: the Eilers method of background estimation was implemented following a preliminary analysis which identified the background estimation method superior to the standard two window method used in pre-processing for the IL2 test and BDX008. The selected parameters managed background across the m/z of interest, through all peak intensities, and reasonably well within peak clusters (where the improvement over the two window method is best observed).
Normalization by bin method: the bin method was used to compare clinical groups of interest to ensure that normalization windows are not selected that have desirable characteristics for distinguishing the groups of interest. The windows, or bins, capture regions of similar behavior in the spectra. For example, peak clusters are contained within a single bin rather than evaluating single peaks individually. The initial normalization bin definitions can be found in Table 12. With the limited m/z range of interest, normalization bins greater than 30 kDa were excluded in the normalization bin analysis. As a second step, the normalization windows were reduced using the many replicates of reference samples that are spotted alongside test samples on every batch, which serve as quality control and for batch corrections, to remove bins that are intrinsically unstable. To do this, we evaluated the CVs of all bins for 160 reference replicates collected in 40 batches. A CV cutoff of 0.18 was applied. Bins with CVs greater than 0.18 were no longer considered for normalization as these surpassed the threshold. This reduced the normalization bins from 77 to 58 bins. The reduced set of bins can be found in Table 13.
To further prune the normalization windows, dependence on response category was used to evaluate CVs and univariate p values. Using the samples in the development set (n=85), the samples from patients achieving a complete response (CR, n=18) were compared to all other patient spectra (partial response, no response, stable disease, or progressive disease) to compute univariate p values for each of the bins. This approach was used to remove normalization windows that may be important for distinguishing the clinical groups CR vs other. A p value cutoff of 0.20 was applied (bins with p values below 0.20 were rejected) and a CV cutoff of 0.25 (bins above 0.25 were rejected). The list of normalization windows was reduced to 11 bins that can be found in Table 14.
The resulting normalization scalars were compared between the response groups to ensure the combination of windows was not significantly associated with the clinical groups. The plot in
Average spectra alignment: the peak alignment of the average spectra is typically very good; however, a fine-tune alignment step was performed to address minor differences in peak positions in the spectra. A set of 26 alignment points was identified and applied to the analysis spectra (Table 15) using a calibration tolerance of 800 ppm. The range of interest for calibration was limited to 3-32 kDa.
Feature Definitions were selected by comparing spectra from each clinical group (defined by CR or other). Several features were identified that may have heightened susceptibility to peptide modifications that take place during the sample preparation procedure. These manifest themselves in specific m/z regions of the spectra where the peaks change in intensity and shape and may depend on the position on the plate where the sample was spotted. These m/z regions were excluded from feature selection. A final set of 418 feature definitions were applied to the spectra, and these are listed in Table 16. An example of features defined using the described method is displayed in
Feature Reduction: a subset of 52 of the 418 features was used to select the individual reference spectra to be used for the baseline reference in batch correction and for computing the correction function used in batch correction. All 418 features were used in reference selection for all further batches. The criteria for selecting the subset were that there could only be 3 features per each m/z interval of approximately 1 kDa and that these should be representative of the intensity range within the kDa interval (i.e., represent high, medium, and low intensities). To ensure that stable features were used for batch correction, CVs over the features were computed using 160 replicate reference spectra. For each approximately 1 kDa interval, the features were ranked by CV and intensity. A visual inspection of each feature in combination with the ranked CV and the intensity demands were used to select the subset of 52 features.
Reference Spectrum Analysis: two preparations of the reference sample, SerumP3, were plated at the beginning (1,2) and end (3,4) of each batch of test samples. The purpose of these samples is to ensure that variations by batch due to slight changes in instrument performance (for example, aging of the detector) can be corrected for. The section below describes the batch correction procedure. To perform batch correction, one spectrum must serve as the reference for the batch and this is an average of the spectra from one of the preparations from the beginning and one from the end of the batch. A procedure for selecting the pair is first described.
The reference samples were preprocessed as described above. Fifty-two features were used to evaluate the possible combinations (1-3, 1-4, 2-3, 2-4). Each possible combination of replicates was compared using the function:
A=min(abs(1−ftrval1/ftrval2),abs(1−ftrval2/ftrval1))
where ftrval1 (ftrval2) is the value of a feature for the first (second) replicate of the replicate pair. This quantity A gives a measure of how similar the replicates of the pair are. For each feature, A is reported. If the value is >0.5, then the feature is determined to be discordant, or ‘Bad’. A tally of the bad features is reported for each possible combination. If the value of A is <0.1, then the feature is determined to be concordant and reported as ‘Good’. A tally of the Good features is reported for each possible combination. Using the tallies of Bad and Good features from each possible combination, we computed the ratio of Bad/Good. The combination with the lowest ratio was reported as the most similar combo and unlikely to contain any systematic or localized outlier behavior in either of the reference spectra. Finally, if no ratio can be found that is less than 0.2, then the batch is a failure. Table 17 reports the combinations that were found most similar for each batch.
Batch Correction: Run 1 Batch 1 was used as the baseline batch to correct all other batches. The reference spectrum was used to find the correction coefficients for each of the batches by the following procedure. Within each batch j ( ), the ratio
and the average amplitude Āij=1/2(Aij+Ai1) are defined for each ith feature centered at (m/z)i, where Aij is the average reference spectra amplitude of feature i in the batch being corrected and is the reference spectra amplitude of feature i in batch 1 (the reference standard). It is assumed that the ratio of amplitudes between two batches follows the dependence
r(Ā,(m/z))=(a0+a1 ln(Ā))+(b0+b1 ln(Ā))(m/z)+c0(m/z)2.
On a batch to batch basis, a continuous fit is constructed by minimizing the sum of the square residuals, Δj=Σi({circumflex over (r)}ij−rj(a0,a1,b0,b1,c0))2, and using the experimental data of the reference sample. The SerumP3 reference samples are used to calculate the correction function. Steps were taken to not include outlier points in order to avoid bias in the parameter estimates. The values of the coefficients a0, a1, b0, b1 and c0, obtained for the different batches are listed in Table 18. The projection in the {circumflex over (r)}ij versus (m/z)i plane of the points used to construct the fit for each batch of reference spectra, together with the surface defined by the fit itself, is shown in
Once the final fit, rj(Ā,(m/z)), is determined for each batch, the next step is to correct, for all the samples, all 418 features (with amplitude A at (m/z)) according to
After this correction, the corrected (Āij, (m/z)i,{circumflex over (r)}ij) feature values calculated for reference spectra lie around the horizontal line defined by r=1, as shown in
Partial Ion Current (PIC) normalization: the dataset was examined to find regions of intrinsic stability to use as the final normalization windows. First, p values comparing the original response groups (CR vs other) were computed. Features with p values less than 0.10 were excluded resulting in 271 features (of 418) to be used in the PIC analysis. As a result of the PIC analysis, 39 features were selected for PIC normalization and these are listed in Table 20.
To normalize, the feature values from the listed features were summed for each spectrum to compute a normalization scalar. All feature values were then divided by the normalization scalar per sample to arrive at the final table used in for new classifier development. The normalization scalars were again examined by clinical group to check that the combined features, i.e., the normalization scalars themselves, were not correlated with clinical group. The plot in
New classifier development was carried out using the Diagnostic Cortex platform, shown schematically in
Definition of Class Labels: while some preliminary approaches explored for classifier development employed well-defined class labels, such as response categories, these proved to be unsuccessful in creating classifiers with good performance. All approaches used for purposes of the invention use time-to-event data for classifier training. In this situation class labels are not obvious and, as shown in
Creation and Filtering of Mini-Classifiers: the development set samples are split into training and test sets in multiple different random realizations. Six hundred and twenty five realizations were used. The diagnostic cortex platform works best when training classes have the same number of samples. Hence, if classes have different numbers of members, they are split in different ratios into test and training.
Many k-nearest neighbor (kNN) mini-classifiers (mCs) that use the training set as their reference set are constructed using subsets of features. All classifiers described herein use k=9. The classifiers described herein use only mCs with single features and pairs of features.
To target a final classifier that has certain performance characteristics, the mCs are filtered as follows. Each mC is applied to its training set and performance metrics are calculated from the resulting classifications of the training set. Only mCs that satisfy thresholds on these performance metrics pass filtering to be used further in the process. The mCs that fail filtering are discarded. All classifiers presented in this report used filtering based on hazard ratios. For hazard ratio filtering, the mC is applied to its training set. The hazard ratio for a specified outcome (here PFS) is then calculated between the group classified as Early and the rest classified as Late. The hazard ratio must lie within specified bounds for the mC to pass filtering.
Combination of mini-classifiers using logistic regression with dropout: once the filtering of the mCs is complete, the mCs are combined into one master classifier (MC) using a logistic regression trained on the training set class labels. To help avoid overfitting the regression is regularized using extreme drop out with only a small number of the mCs chosen randomly for inclusion in each of the logistic regression iterations. The number of dropout iterations is selected based on the typical number of mCs passing filtering to ensure that each mC is likely to be included within the drop out process multiple times. Classifiers presented in this report left in 10 randomly selected mCs per drop out iteration and used either 10,000 or 100,000 drop out iterations.
Training/Test splits: the use of multiple training/test splits avoids selection of a single, particularly advantageous or difficult training set for classifier creation and avoids bias in performance assessment from testing on a test set that could be especially easy or difficult to classify.
The output of the logistic regression that defines each MC is a probability of being in one of the two training classes (Early or Late). Applying a threshold to this output produces a binary label (Early or Late) for each MC. For all classifiers presented herein, a cutoff threshold of 0.5 was used. To produce an overall final classification, a majority vote is done across all MCs (“ensemble average”). When classifying samples in the development set this is modified to incorporate in the majority vote only MCs where the sample is not in the training set (“out-of-bag majority vote”).
It is also possible to directly average the MC probabilities to yield one average probability for a sample. When working with the development set, this approach is adjusted to average over MCs for which a given sample is not included in the training set (“out-of-bag” estimate). These average probabilities can then be converted into a binary classification by applying a cutoff. Applying a cutoff of 0.5 to the averaged probabilities gives very similar classifications to using a cutoff of 0.5 on the individual MC probabilities and then performing the majority vote over the MCs. However, this approach was not used to produce the results shown herein.
Classifier 1/Design: this classifier consists of a hierarchical combination of 2 sub-classifiers, each of them developed using subsets of mass spectral features which have been identified as being associated with the Complement and Acute Response protein functional groups, respectively. This was done using the principles of gene set enrichment analysis (GSEA).
Gene Set Enrichment Analysis (GSEA) is a method frequently used in gene expression analysis studies when expression values for a large number of genes are available for a number of biological samples for which either categorical class information or the value of some continuous variable is also known [Mootha et al., Nat Genet. 2003; 34(3):267-73; Subramanian et al., Proc Natl Acad Sci USA 2005; 102(43): 15545-50]. The approach looks for a pattern of correlations of gene expression of the samples with the associated categorical or continuous variable depending on the biological function of the genes. The approach was developed for use in gene expression studies, but it can be equally well applied to protein expression data, and this is the context in which it will be discussed here.
The general approach is to rank the entire list of measured proteins according to their correlation with a categorical label or continuous variable, from highest to lowest. Subsets of proteins from the universe of measured proteins are defined based on their biological functions, e.g., using well-known databases such as UniProt or GeneOntology/AmiGO2. The method then looks for over- or under-representation of the proteins in each subset as a function of rank in the ranked list of all measured proteins. The method implemented herein follows the approach of Subramanian. No corrections are made for multiple comparisons.
A cohort of 49 serum samples is available with matched protein expression data and deep MALDI spectra. The protein expression data comes from running the SomaLogic 1129 protein panel on the serum samples. Any mass spectral feature values or test classifications can be generated on this spectra; data and correlated with the protein expression data. Investigations used 29 different protein sets defined as the intersection of the results of querying protein databases on specific biological process and the list of 1129 measured proteins. Protein sets were selected to include functions expected to play a role in the immune system and cancer treatment efficacy in general, as well as others not expected to be relevant, as a control. There is overlap between some of the protein sets, as would be expected from the similar biological keywords used in their construction.
GSEA method for association of mass spectral features with protein functional groups: for this application the correlation of protein expression data with mass spectral feature values is investigated, i.e., the continuous variable used in GSEA is a mass spectral feature value. The GSEA method was applied for each of the 418 mass spectral features. Features with a p<0.05 for the GSEA for a particular protein functional set were designated as associated with that biological function. This is illustrated schematically in
GSEA method for association of test classifications with protein functional groups: for this application, a developed test (Classifier 2) is applied to the deep MALDI spectra acquired from the 49 sample cohort and test classifications are generated which are then correlated with the protein expression data. This method was used to assess what biological functions may be associated with test classifications.
The first sub-classifier was designed using 83 of the 85 samples in the analysis cohort as the development set. Spectra from two patients not evaluable for response were not included in the training of this sub-classifier. The subset of 142 mass spectral features associated with complement activation and with m/z<25 kDa were used in the Diagnostic Cortex platform to create a classifier able to stratify patients into two groups with better and worse PFS. No feature deselection was used, i.e., all 142 mass spectral features associated with complement were used at each step of refinement of the class labels and first sub-classifier. Twenty-nine samples of the analysis cohort were assigned to the poor performing group and these were given an “Early” classification. The remaining 56 samples, assigned to the good performing group, were used as the development set for a second sub-classifier. This sub-classifier was trained on the subset of 37 mass spectral features which had been identified as being associated with acute response (AR). The second classifier again used no feature deselection and stratified patients well into groups with better or worse PFS. Samples in the good outcome group were assigned a “Late” classification and samples in the poor outcome group were assigned an “Early” classification. The feature subsets used in the creation of the first sub-classifier and the second sub-classifier are given in Table 21. In some embodiments, for each respective feature given in Table 21, the corresponding m/z range given in Table 16 was used to calculate the feature value for the respective feature. For example, for the feature “3125” listed in Table 21 for sub-classifier 1, a mass spectrograph of a sample from a target entity was integrated between 3118.81 (m/z) and 3130.38 (m/z) as specified in Table 16 (entry number 3: 3118.81, 3124.60, 3130.38) in order to arrive at the feature value for this feature. This feature value was then used in pattern classification techniques as discussed herein in order to classify a target entity.
Samples classified by the first sub-classifier (based on complement-associated mass spectral (MS) features) as belonging to the poor performing group were given the “Bad” final classification. Those assigned to the good performing group by the first sub-classifier were given a classification of “Good” if the second sub-classifier (based on acute response-related MS features) gave a classification of “Late”, and a classification of “Intermediate” if the second sub-classifier gave a classification of “Early.”
Results: the developed classifier assigned 29 Bad classifications (34%), 24 Intermediate classifications (28%), and 32 Good classifications (38%). Classifications by sample are given in Table 22. Baseline characteristics by test classification are summarized in Table 23 and response to therapy also split by test classification is shown in Table 24. Kaplan-Meier plots of PFS split by test classification are shown in
Reproducibility: a rerun of all 85 analysis samples was performed. This was carried out with completely independent sample preparation and spectral acquisition and processing after a second machine qualification run. The generated spectra were analyzed and classifications compared with those of the initial run to evaluate the reproducibility of the test. Table 26 shows the test classification concordance between the two runs. The overall concordance is 76/85=89%.
Classifier 2/Design: this classifier consists of the combination of the 2 sub-classifiers of classifier 1 and an existing third sub-classifier from a previously developed test (“IS13”). This pre-existing test was constructed using melanoma samples with the goal of identifying patients with durable benefit from immunotherapies in poor prognosis groups and assigns the classifications of EarlyEarly or EarlyLate (worse or better outcome on immunotherapy).
Samples classified by the first sub-classifier (based on complement MS features) as belonging to the poor performing group were given the “Bad” final classification. Those samples assigned to the good performing group both by the first and second sub-classifiers were given a classification of “Good”. The classification of the remaining samples, assigned to the good performing group by the first sub-classifier and to the poor performing group by the second sub-classifier, was based on the classification given by the third sub-classifier: if the classification was EarlyEarly the final classification was Bad and if the classification was EarlyLate the final classification was Good. This procedure for assigning classifications is summarized in
Results: classifier 2 assigned 44 Bad classifications (52%) and 41 Good classifications (48%). Classifications by sample are listed in Table 22. Baseline characteristics by test classification are summarized in Table 27, and response to therapy also split by test classification is shown in Table 28. Kaplan-Meier plots of PFS split by test classification are shown in
Reproducibility: a rerun of all 85 analysis samples was performed. This was carried out with completely independent sample preparation and spectral acquisition and processing after a second machine qualification run. The generated spectra were analyzed and classifications compared with those of the initial run to evaluate the reproducibility of the test. Table 30 shows the test classification concordance between the two runs. The overall concordance is 78/85=92%.
Protein Set Enrichment Analysis (PSEA), a method inspired by gene set enrichment analysis, was used to look for an association of the test classifications (Classifier 2) with protein functional groups. To do this, an independent set of 49 samples was used where paired deep MALDI spectra and protein panel (Somalogic, Boulder, Colo.) results were available. Of the 49 samples 35 classified as Bad and 14 as Good.
The results for 29 different protein functional groups tested are shown in Table 31. P values are not corrected for multiple comparisons. At the α=0.05 significance level, associations of the test classifications were found with acute inflammation, complement, acute response and acute phase. In addition, at the α=0.10 significance level, associations of the test classifications were found with glycolytic processes and extracellular matrix.
Plots of the running sum, RS(i), produced during PSEA are shown in
Both BDX008 and IL2 tests were able to stratify patients receiving adoptive cell transfer therapy into two groups with better and worse progression-free survival. BDX008 identified a group of approximately one third of patients with particularly poor outcomes (2 year PFS of 7%). The IL2 test identified a group of around one third of patients with particularly good outcomes (4 year PFS of 49%).
New classifier development was able to produce two new tests specifically tailored to the adoptive cell transfer application. Classifier 1 split the analysis cohort into three groups with poor, intermediate and good outcomes. The best performing group, containing 38% of patients, had four year PFS of 52% and a response rate (CR+PR) of 75%. Classifier 2 integrated classifier 1 with an existing Biodesix classifier to stratify patients into two roughly equal sized groups with better and worse outcomes. The good performing group had four year PFS of 50%, a response rate of 71%, and also included the two patients who experienced stable disease in excess of four years. Validation of these new tests can be performed in independent patient cohorts.
Appendix: test classifications are provided for 16 plasma samples collected before adoptive cell transfer (Table 36).
