Abstract
Methods for selecting a cancer patient for immunotherapy comprise establishing a total passenger gene mutation burden from a tumor of a cancer patient, generating a background distribution for the mutational burden of the tumor, normalizing the total passenger gene mutation burden against the background distribution, and categorizing the cancer patient as an immunotherapy responder when the total passenger gene mutation burden is greater than the mean of the background distribution. When the cancer patient is an immunotherapy responder, the patient may be administered an immunotherapy regimen that comprises activation/inhibition of T cell receptors that promote T cell activation and/or prolong immune cytolytic activities.
Description
lmmunotherapy Methods for Patients Whose Tumors Carry a High Passenger Gene Mutation Burden REFERENCE TO RELATED APPLICATION This application claims benefit of U.S. Provisional ation No. 62/560,955 filed September 20, 2017, and is hereby incorporated herein by reference in its entirety.
FIELD The disclosure relates lly to the field of immunotherapy. More particularly, the sure s to methods of administering an immunotherapy regimen to patients whose tumors have a high passenger gene mutation burden.
BACKGROUND Various publications, ing patents, patent applications, published patent applications, accession numbers, technical articles and scholarly articles are cited throughout the specification. Each ofthese cited publications is incorporated by reference, in its entirety and for all purposes, in this document.
Recent studies suggested that patients with higher overall tumor mutational burden (TMB) in their tumors are more likely to benefit from immunotherapy treatment due to the increase in neo-antigen presentation that could elicit an immune response. However, the overall mutational burden includes driver gene mutations that could actually suppress immunogenicity and decrease sensitivity to the treatment.
No existing method has been developed for the purpose of identifying passenger genes and their mutations to assess immunogenicity. These and other shortcomings are addressed in the t disclosure.
SUMMARY It is to be understood that both the following l description and the following detailed description are exemplary and explanatory only and are not ctive.
In a first aspect, the disclosure provides a method comprising receiving genetic sequence data, wherein the genetic sequence data comprises a plurality of genes and is derived from a plurality of biological samples collected from subjects having a plurality of disease types, identifying a plurality of mutated genes for each of the plurality of biological samples, wherein each of the mutated genes comprises a c sequence having at least one non-synonymous somatic mutation, determining a tumor mutational burden for each biological sample based on a number of mutated genes in each biological sample, for each disease type, determining an e tumor mutational burden ofthe plurality of mutated genes in the plurality of biological samples based on the ined numbers of mutated genes in each biological sample, for each mutated gene and each disease type, determining a fraction of biological samples comprising the mutated gene, for each mutated gene, determining a correlation coefficient between the average tumor mutational burden and the fraction of biological samples sing the mutated gene. A higher correlation coefficient tes that a particular gene is more likely to acquire somatic mutations in the cancer types with higher overall mutation frequency (e.g., passenger gene), whereas a lower correlation cient indicates that a particular gene is less likely to acquire somatic mutations in the cancer types with higher l mutation frequency (e.g., not a passenger gene) In another aspect, the disclosure provides methods for selecting a cancer patient for immunotherapy. In general, the methods comprise establishing a total passenger gene mutation burden from a tumor of the cancer patient, generating a background distribution for the mutational burden of the tumor, normalizing the total passenger gene mutation burden against the background bution, and categorizing the cancer patient as an immunotherapy responder when the total ger gene mutation burden is at least about one and a half rd ions greater than the mean ofthe background distribution.
Generating a background bution may comprise establishing the mutational burden from a ity of samples of randomly selected genes obtained from the tumor, but the number of randomly selected genes in each sample preferably is equal to the number of passenger genes used to compute the total passenger gene mutation burden.
Normalizing the total passenger gene mutation burden against the background distribution may comprise generating a e indicating the number of standard deviations from the mean of the ound distribution.
The methods may further comprise categorizing a mutated gene in the tumor as a passenger gene. Categorizing a mutated gene in the tumor as a passenger gene may comprise selecting a mutated gene from the tumor and matching the mutated gene to a data structure comprising passenger genes established according to a passenger gene index.
The passenger gene index may comprise a ation cient between the fraction of samples comprising the mutated gene obtained from a cancer patient cohort and the median number of mutated genes in each type of tumor within the cancer patient .
The methods may further comprise administering to the cancer patient an immunotherapy regimen. The immunotherapy regimen may se administering to the patient an inhibitor of a Tcell inhibitory receptor. The immunotherapy regimen may se administering to the patient activator of T cell activating receptor.
The immunotherapy regimen may comprise administering to the t an antibody that binds to PD1. The antibody that binds to PD1 may comprise at least the heavy chain variable region (HCVR) sequence of SEQ ID NO: 21 and a light chain variable , or may comprise at least the light chain variable region (LCVR) sequence ofSEQ ID NO: 22 and a heavy chain variable . The antibody that binds to PD1 may se the HCVR or SEQ ID NO: 21 and the LCVR or SEQ ID NO: 22. That antibody that binds to PD1 may be administered in combination with an antibody that binds to LAG3.
The immunotherapy regimen may comprise administering to the patient an antibody that binds to PDL1. The antibody that binds to PDL1 may comprise at least the HCVR sequence of SEQ ID NO: 122 and a LCVR, or may comprise at least the LCVR sequence of SEQ ID NO: 123 and a HCVR. The antibody that binds to PDL1 may comprise the HCVR or SEQ ID NO:122 and the LCVR or SEQ ID NO: 123. That antibody that binds to PDL1 may be administered in combination with an antibody that binds to LAG3.
The immunotherapy regimen may comprise administering to the patient an antibody that binds to LAG3 The dy that binds to LAGB may comprise at least the HCVR sequence of SEQ ID NO: 93 and a LCVR, or may comprise at least the LCVR sequence of SEQ ID NO: 94 and a HCVR. The antibody that binds to LAGS may comprise the HCVR or SEQ ID NO: 93 and the LCVR or SEQ ID NO: 94. That antibody that binds to LAG3 may be administered in combination with an antibody that binds to PD1 or with an antibody that binds to PDL1.
Additional advantages will be set forth in part in the description which follows or may be learned by practice. The advantages will be realized and attained by means ofthe elements and combinations particularly pointed out in the appended claims.

It has been observed in accordance with the sure that, in , the total mutational burden of passenger genes, as opposed to the total mutational burden of all genes, serves as an accurate indicator of whether a cancer patient is likely to respond vely to immunotherapy. Tumor mutational burden (TMB) may refer to a number of mutations within the coding region of a tumor genome. Mutated genes were assessed and classified according to their status as a ger gene by way of a passenger gene index, which was used as a metric to identify passenger genes from a large-scale cancer genome analysis. It was observed that identified passenger genes were enriched for gene es known for excessive passenger mutations, including genes encoding large proteins, genes with low expression level, and genes with late DNA replication time. The total mutational burden of passenger genes positively correlated with tumor immunogenicity and bly predicted patient clinical outcomes. Accordingly, the disclosure features s to classify patients according to their passenger gene mutation burden, as part of an immunotherapy regimen. ln cancer biology, driver mutations are understood to be at least casually implicated in cancer formation or cell transformation. And passenger mutations are understood to be those that do not confer a growth advantage or contribute to cancer development. See Stratton MR et al. (2009) Nature. 458:719—24. Thus, passenger genes include genes that comprise passenger mutations. Non-limiting examples of mutations include substitutions, inversions, insertions, and deletions of one or more nucleotides, codons, genes, or somes, as well as copy number variations.
In one , the disclosure features methods and systems for fying or classifying passenger genes. Identified passenger genes are ed for families known for excessive ger mutations, such as extremely large proteins and genes with low expression level or late DNA replication time. In some embodiments, passenger genes can be identified or classified according to a Passenger Gene Index (PGI). Thus, for e, passenger genes can be identified or classified according to a PGI that comprises a correlation coefficient between a fraction of samples obtained from a cancer patient cohort that comprises the mutated gene and the median number of mutated genes in each type of tumor within the cancer t cohort. Based on identification of passenger genes, a data structure comprising passenger genes can be established.
Individual cancer patients can be screened to determine whether their tumors comprise passenger genes, as well as to determine the total passenger gene mutation burden of their tumor. Based on the patient’s passenger gene on burden, the patient can be classified according to their capacity to respond positively to immunothera py.
Immunotherapy generally enhances the body’s natural immune response to cancer, and includes, but is not limited to, the enhancement of the T cell response to the tumor.
An example of a methodology by which a cancer patient may be assessed for immunotherapy responsiveness is shown in In general, the methods comprise ishing a total passenger gene mutation burden from a tumor of a cancer patient (110), generating a background distribution for the mutational burden of the tumor (120), normalizing the total passenger gene mutation burden against the background distribution (130), and categorizing the cancer t as an immunotherapy responder (140).
Also disclosed are methods of treating a cancer patient with an immunotherapy after being assessed for immunotherapy responsiveness. For example, disclosed are methods of treating a cancer patient with an immunotherapy comprising determining if a cancer patient is an immunotherapy der comprising establishing a total passenger gene mutation burden of the tumor of the patient; generating a background bution for the mutational burden of the tumor; normalizing the total passenger gene mutation burden against the ound distribution; and categorizing the cancer t as an immunotherapy responder genotype when the total ger gene mutation burden is at least about one and a half standard deviations greater than the mean ofthe background bution; and administering an immunotherapy to the cancer patient categorized as an immunotherapy responder.
Further disclosed are methods for treating a patient with an inhibitor of a T cell inhibitory receptor or a receptor on a tumor cell or a munotherapeutic treatment, wherein the patient is ing from cancer, the method comprising the steps of: determining whether the patient is an immunotherapy responder by: obtaining or having obtained a biological sample from a tumor of the patient; performing or having performed a genotyping assay on the biological sample to determine if the patient has an immunotherapy responder genotype by, cing the biological sample to generate sequence data; establishing, based on the ce data, a total passenger gene mutation burden of the tumor of the patient; generating, based on the sequence data, a background distribution for the mutational burden of the tumor; normalizing the total passenger gene mutation burden against the background distribution; and categorizing the patient as an immunotherapy der pe when the total passenger gene mutation burden is at least about one and a half standard deviations greater than the mean of the background distribution; wherein if the patient has an immunotherapy responder genotype, then administering a therapeutically effective amount of an inhibitor of a T cell inhibitory receptor or a receptor on a tumor cell, wherein if the patient does not have an immunotherapy responder genotype, then administering a non-immunotherapeutic treatment. In some embodiments, a risk of unfavorable clinical outcome for a patient having an immunotherapy responder genotype is lower following the administration ofthe therapeutically effective amount of the inhibitor ofa T cell inhibitory receptor or a receptor on a tumor cell than it would be ifthe patient were stered the non— immunotherapeutic treatment. In some embodiments, T cell activation and/or immune cytolytic ty in a patient having an immunotherapy responder genotype is higher following the administration of the therapeutically ive amount of the inhibitor of a T cell inhibitory receptor or a receptor on a tumor cell than it would be if the patient were administered the non-immunotherapeutic treatment.
Disclosed are immunotherapies for use in the method of ng a cancer patient, the method comprising determining if a cancer patient is an immunotherapy responder by, ishing a total passenger gene mutation burden of a tumor ofthe patient; generating a background bution for the mutational burden of the tumor; normalizing the total passenger gene mutation burden against the background distribution; categorizing the cancer patient as an immunotherapy responder pe when the total passenger gene mutation burden is at least about one and a half standard deviations greater than the mean of the background distribution; and administering the therapy to the cancer patient rized as an immunotherapy responder.
In some preferred embodiments, establishing a total passenger gene mutation burden from a tumor of a cancer patient (110) may comprise determining the total passenger gene mutation burden by any sequencing method that is used to ine the coding regions ("exome") of a tumor genome. Whole genome sequencing methods can also be used.
Exome mutations can be determined using sequencing methods known in the art.
For example, US 2013/0040863, incorporated herein by nce, describes methods for ining the nucleic acid sequence of a target nucleic acid molecule, including sequencing by synthesis, sequencing by ligation or sequencing by hybridization, including for mutation detection, whole genome sequencing, and exon sequencing. If desired, various amplification methods can be used to generate larger quantities, particularly of limited nucleic acid samples, prior to sequencing.
Sequencing by synthesis (585) and sequencing by ligation can be performed using ePCR, as used by 454 Lifesciences (Branford, Conn.) and Roche Diagnostics (Basel, Switzerland). Nucleic acids such as genomic DNA or others of interest can be fragmented, dispersed in oil emulsions and diluted such that a single c acid fragment is separated from others in an emulsion droplet. A bead, for example, containing multiple copies of a primer, can be used and amplification carried out such that each emulsion t serves as a reaction vessel for amplifying multiple copies ofa single nucleic acid fragment. Other methods can be used, such as bridging PCR (Illumina, Inc.; San Diego Calif.), or polony amplification (Agencourt/Applied Biosystems). US 2009/0088327; US 2010/0028885; and US 2009/0325172, each ofwhich is incorporated herein by reference.
Methods for manual or automated sequencing are well known in the art and include, but are not limited to, Sanger sequencing, Pyrosequencing, cing by hybridization, sequencing by ligation and the like. Sequencing methods can be performed manually or using automated methods. rmore, the amplification methods set forth herein can be used to prepare nucleic acids for sequencing using commercially available methods such as automated Sanger sequencing (available from Applied Biosystems, Foster City, Calif.) or quencing (available from 454 Lifesciences, Branford, Conn. and Roche Diagnostics, Basel, rland); for sequencing by synthesis methods commercially available from Illumina, Inc. (San Diego, Calif.) or Helicos (Cambridge, Mass.) or sequencing by ligation methods being developed by Applied Biosystems in its urt platform (see also Ronaghi et al., Science 2812363 (1998); Dressman et al., Proc. Natl. Acad. Sci. USA 100:8817—8822 (2003); Mitra et al., Proc. Natl. Acad. Sci. USA 100:55926-5931 ), incorporated herein by reference,.
A tion of nucleic acids in which a primer is hybridized to each nucleic acid such that the nucleic acids form templates and modification of the primer occurs in a template directed fashion. The modification can be detected to determine the sequence of the te. For example, the primers can be modified by extension using a rase and extension of the primers can be red under conditions that allow the identity and location of ular nucleotides to be determined. For example, extension can be monitored and sequence of the template nucleic acids determined using pyrosequencing, which is described in US 2005/0130173, US 2006/0134633, US. Pat. No. 4,971,903; US. Pat.
No. 6,258,568 and US Pat. No. 6,210,891, each ofwhich is incorporated herein by reference, and is also commercially ble. Extension can also be monitored according to addition of labeled nucleotide analogs by a polymerase, using methods described, for example, in US. Pat. No. 4,863,849; US. Pat. No. 5,302,509; US. Pat. No. 594; US.
Pat. No. 5,798,210; US. Pat. No. 6,001,566; US. Pat. No. 6,664,079; US. 2005/0037398; and US. Pat. No. 7,057,026, each of which is incorporated herein by nce. Polymerases useful in sequencing methods are typically polymerase enzymes derived from natural sources. It will be understood that polymerases can be modified to alter their icity for modified nucleotides as described, for example, in WO 01/23411; U.S. Pat. No. 5,939,292; and WO 010, each of which is incorporated herein by reference. Furthermore, polymerases need not be d from biological systems. Polymerases that are useful in the invention include any agent capable of catalyzing extension of a nucleic acid primer in a manner directed by the sequence of a template to which the primer is hybridized. Typically polymerases will be protein enzymes isolated from biological systems.
Alternatively, exon sequences can be determined using sequencing by ligation as described, for example, in Shendure et al. Science 28-1732 (2005); U.S. Pat. No. 675; and U.S. Pat. No. 5,750,341, each h is incorporated herein by reference.
Sequences of template nucleic acids can be determined using sequencing by ization methods such as those described in U.S. Pat. No. 6,090,549; U.S. Pat. No. 6,401,267 and U.S.
Pat. No. 6,620,584, each of which is incorporated herein by reference.
If desired, exon sequence products are ed using a ligation assay such as oligonucleotide ligation assay (OLA). Detection with OLA es the te-dependent ligation of two smaller probes into a single long probe, using a target sequence in an amplicon as the template. In a particular embodiment, a single-stranded target sequence includes a first target domain and a second target domain, which are adjacent and contiguous. A first OLA probe and a second OLA probe can be hybridized to complementary sequences of the respective target domains. The two OLA probes are then covalently attached to each other to form a modified probe. In embodiments where the probes hybridize directly adjacent to each other, covalent linkage can occur via a ligase. One or both probes can include a nucleoside having a label such as a peptide linked label. ingly, the presence ofthe ligated t can be determined by detecting the label.
In particular embodiments, the ligation probes can include priming sites ured to allow amplification of the ligated probe product using primers that hybridize to the priming sites, for example, in a PCR reaction.

In some preferred embodiments, generating a background distribution (120) comprises ishing the mutational burden from a plurality of samples of randomly selected genes obtained from the tumor, provided that the number of randomly selected genes in each sample is equal to the number of passenger genes used to compute the total passenger gene mutation burden.
In some preferred embodiments, izing the total passenger gene mutation burden against the background bution (130) comprises generating a z—score indicating the number of standard deviations from the mean of the background distribution. In an alternative embodiment, p—values can be used. Z-scores can be correlated to p-values. For example, a z-score of 1.65 equals a p-value of p<0.05 and a z-score of 2.3 equals a p-value of p<0.01.
Categorizing the cancer t as an immunotherapy responder may be according to the relationship of the total passenger gene mutation burden to the mean of the background distribution.

An example of a methodology for ishing a total passenger gene on burden from a tumor of a cancer patient is shown in and A genetic sample can be obtained/received (202). The genetic sample can be from a cancer patient. The genetic sample can be from a tumor ofthe cancer patient. The genetic sample can be sequenced, resulting in genetic sequence data.
In some embodiments, the sequence data can be obtained or received through any method described herein. For example, the sequence data can be obtained directly, by performing a sequencing process on a sample. Alternatively, or additionally, the sequence data can be obtained indirectly, for example, from a third party, a database and/or a publication. In some embodiments, the sequence data are ed at a computer system, for example, from a data storage device or from a separate computer system.
In some ments, the sequence data can comprise bulk sequence data. The term "bulk sequencing" or "next generation sequencing" or vely parallel sequencing" refers to any high throughput sequencing technology that elizes the DNA and/or RNA sequencing s. For example, bulk sequencing methods are typically capable of producing more than one million polynucleic acid amplicons in a single assay. The terms "bulk sequencing,II IImassively parallel sequencing," and "next generation sequencing" refer only to general methods, not necessarily to the acquisition of greater than 1 million ce tags in a single run. Any bulk sequencing method can be implemented in the disclosed methods and systems, such as reversible ator chemistry (e.g., Illumina), quencing using polony emulsion ts (e.g., Roche), ion semiconductor sequencing (IonTorrent), single molecule sequencing (e.g., Pacific Biosciences), massively parallel signature sequencing, etc.
In some embodiments, the sequence data can be produced by any sequencing method known in the art. For example, in some embodiments the sequencing data are produced using chain termination sequencing, sequencing by on, sequencing by synthesis, pyrosequencing, ion semiconductor sequencing, single-molecule real-time sequencing, sed sequencing, dilute—‘n‘-go sequencing, and/or 454 sequencing.
In some embodiments, the sequence data are the result of a process whereby a nucleic acid amplification process is performed to amplify at least part of one or more genomic locus or transcript, ed by the sequencing ofthe resulting amplification t. Examples of c acid amplification processes useful in the performance of methods disclosed herein include, but are not limited to, polymerase chain reaction (PCR), LATE-PCR, ligase chain on (LCR), strand displacement amplification (SDA), transcription mediated amplification (TMA), self-sustained sequence replication (35R), QB ase based amplification, nucleic acid sequence-based amplification (NASBA), repair chain reaction (RCR), boomerang DNA amplification (BDA) and/or rolling circle amplification (RCA).
In some embodiments, the method includes the step of performing a sequencing process on a sample. Any sample can be used, so long as the sample contains DNA and/or RNA from a tumor of a patient. The source of the sample may be, for e, solid tissue, as from a fresh, frozen and/or preserved organ, tissue sample, biopsy, or aspirate; blood or any blood constituents, serum, blood; bodily fluids such as cerebral spinal fluid, amniotic fluid, peritoneal fluid or interstitial fluid.
The genetic sequence data can be analyzed (204) via a computing device to identity driver genes and to determine a number of mutations in the driver genes. Ifthe number of mutations in the driver genes is high (206), an indication can be ted that the patient will respond to the immunotherapy (210). If the number of mutations in the driver genes is low (206), an indication can be generated poor or no response will be seen with immunotherapy (208). Mutations on driver genes could e "hallmarks of cancer" e.g., immune escape.
In an alternate embodiment, the genetic sequence data can be analyzed (212) via a computing device to identify passenger genes and to determine a number of mutations in the passenger genes. Ifthe number of mutations in the passenger genes is high (216), an indication can be generated (210) that the patient will respond to the immunotherapy. If the number of mutations in the passenger genes is low (216), an tion can be generated (208) that poor or no response will be seen with immunotherapy. While passenger genes do not have any causal implication in cancer, mutations on passenger genes can be used to assess immunogenicity. In some embodiments, the genetic sequence data can be analyzed (212) to identify passenger genes, determine a number of mutations in the passenger genes, and determine a background distribution for the mutational burden ofthe tumor. The number of ons in the passenger genes can be analyzed with regard to the background distribution to determine how many standard deviations (if any) the number of mutations in the passenger genes is from the mean. If the number of standard deviations is high (e.g., at least 1, 1.5, 2, 2.5) (216) the cancer patient can be categorized as a better immunotherapy responder (210). Ifthe number of standard deviations is low (216) the cancer patient can be categorized as a poor immunotherapy responder (208).
In some embodiments, the passenger genes can be identified in large-scale cancer genome analysis according to a metric referred to herein as a ger Gene Index (PGI) (212). In some embodiments, the PGI is based on c mutation rates (GMR) of the passenger genes being highly correlated with overall cancer mutation frequencies, also referred to as tumor mutational burden (214). Identified passenger genes are enriched for families known for excessive passenger ons, such as ely large proteins and genes with low sion level or late DNA replication time. More passenger gene mutations will accumulate in cancer samples/types with higher mutations rates, and the average number of mutated genes per sample in each cancer type can be a surrogate for likelihood of passenger mutations in that cancer type. Thus, PGI can be defined, for each gene, X,, as a correlation between percentage sample with gene X; mutation and average number of mutated gene per sample in each cancer type. A higher PGI score indicates that a particulargene is more likely to e somatic mutations in the cancer types with higher overall mutation frequency. Genes with a low PGI show a weak ation n the two variables (e.g., and can be ed in canonical cancer driver genes such as TP53, P|K3CA and KRAS). Genes ranked at the top of the PGI are enriched for gene families known for excessive passenger mutations, e.g., extremely large proteins (>4,000 amino acids), genes spanning large genomic loci (>1Mb), genes with low sion level, genes with late DNA replication time, and the like. A cumulative distribution function (CDF) of these gene families show sharp uptrend at PG|>0.7, while the genes in Catalogue of Somatic Mutations in Cancer (COSMIC) Cancer Gene Census (CGC) are more uniformly distributed. Two-sample orov-Smirnov tests show significant difference in the rank distribution of ger gene es as compared to that of CGC genes (p=8.3><10‘19 for large proteins; p=2.9><10’12 for genomic locus >1Mb; p=6.4><10'35 for low expression; p=2.7><10'29 for late replication). r results are obtained when samples are grouped by mutation rate (instead of cancer type) for computing PGI.
The top passenger genes, based on highest PGI, can be agnostic to tumor type or specific for each tumor type. Thus, in some instances, the top passenger genes can be used generically, regardless of tumor type. Although these top passenger genes do not change regardless of tumor type, the top passenger genes can change over time due to ibility of additional samples. In some instances, the top passenger genes can vary between tumor types. In some instances, the top passenger genes can be identical between tumor types.
Furthermore, ifthe top passenger genes are identical between tumor types, the ranking within that top passenger gene list can vary. For example, the top 50 passenger genes for breast cancer can be cal to the top 50 passenger genes for lung cancer however the number one passenger gene (meaning highest PGI) for breast cancer can be the number five passenger gene for lung cancer. In some instances, the top 50 passenger genes of one tumor type can comprise 1, 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, up to 100 percent of the top 50 passenger genes of a second tumor type. Depending on what range of PGI is included, a list of top 25, 50, 100, 150, 200, 250, 300, 350, 400, 450, 500, or even 2000 plus passenger genes can be included on a top passenger gene list. In some instances, the top passenger genes do not vary among ts. All patients can use the same passenger gene list and each patient will have a different TMB score.

A higher correlation coefficient indicates that a particular gene is more likely to acquire somatic mutations in the cancer types with higher overall mutation frequency (e.g., passenger gene), whereas a lower correlation coefficient tes that a particular gene is less likely to acquire somatic mutations in the cancer types with higher overall mutation frequency (e.g., not a ger gene) In an alternate embodiment, the method (300) can further comprise generating a list of the mutated genes identified as passenger genes. In aspect red embodiment, the list can ent an genicity e for the selected disease.

In some embodiments, the mutated gene can be determined to be a passenger gene based on the correlation coefficient. A higher correlation coefficient indicates that a particular gene is more likely to acquire somatic mutations in the cancer types with higher overall mutation ncy (e.g., passenger gene), whereas a lower correlation coefficient indicates that a particular gene is less likely to acquire somatic ons in the cancer types with higher overall mutation frequency (e.g., not a passenger gene).

The disclosed immunotherapies can be used in ation with other antibody or antigen-binding fragments thereof as well as other anti-cancer therapies. Combination therapies can be administered simultaneously or sequentially. In some embodiments, two or more ies can be formulated together with a pharmaceutically acceptable carrier resulting in a pharmaceutical composition. In some ments, two or more therapies are formulated individually with a pharmaceutically acceptable carrier resulting in two or more pharmaceutical compositions.

It will be nt to those persons skilled in the art that certain carriers may be more preferable depending upon, for instance, the route of stration and concentration of ition being administered. These most typically would be standard carriers for administration of drugs to humans, including solutions such as sterile water, saline, and buffered solutions at physiological pH.

The following examples are provided to describe the disclosure in greater .
They are intended to illustrate, not to limit, the disclosure.
Example 1 Passenger Gene Index The method of Passenger Gene Index (PGI) involves all TCGA samples binned by cancer type, and the median number of mutated genes was determined for each bin.
Mutations were limited only to nonsilent somatic mutations by comparing solid tumors to the blood derived or solid normal counterparts, with the exception in acute myeloid leukemia where blood derived tumors were compared to the solid tissue . Mutation profiles were constructed as a binary matrix such that a bit is set if any locus correspond to the gene s a mutation in that patient. PGI is computed for each gene Xi, as Pearson correlation between fraction of sample with gene Xi mutation and the median number of mutated gene in each cancer type. Before computing the correlations, an infinitesimal amount of uniformly distributed noise was added to the sample fraction with mutation to avoid issues with all zero entries.
Example 2 Z-Score for Driver and Passenger Gene Tumor Mutational Burden The method of Z-score for driver/passengerTMB involves the following. To compute z-score for a TMB, background distribution of the TMB was first established using 1000 randomly selected gene sets of equal size. The numbers of mutated driver/passenger gene were then ed to the background distribution to compute the z-score, ting how many standard deviations the number is from the mean ofthe background. Driver genes were downloaded from COSMIC Cancer Gene Census on January 22, 2015, and passenger genes were defined as top n genes ranked by PGI derived from TCGA data.
Example 3 Passenger Gene Tumor Mutational Burden and Immunotherapy Responsiveness To compute Passenger Gene Index (PGI), a list was ed of nonsilent somatic mutations from 6,685 samples across 20 TCGA tumor types. Somatic ons were determined by comparing tumor genome to that of the germ line, e.g. blood derived normal sample from the same patient. The median number of altered genes per sample ranged from 9 in acute myeloid leukemia to 289 in skin cutaneous melanoma, representing over 32- fold difference between the lowest and the highest mutation rate cancers (. This is consistent with previous ations that skin and lung cancer samples have the highest mutation rates, due to the exposure to environmental mutagens. shows the number of nonsilent c mutations per sample in 6,685 TCGA cancer exomes.
The 20 cancer types included in this study are bladder lial carcinoma (BLCA), breast ve carcinoma (BRCA), cervical squamous cell oma and endocervical adenocarcinoma (CESC), colon/rectum adenocarcinoma (CORE), glioblastoma multiforme (GBM), head and neck squamous cell oma (HNSC), kidney renal clear cell carcinoma (KIRC), kidney renal papillary cell carcinoma , acute myeloid leukemia (LAML), liver hepatocellular carcinoma (LIHC), brain lower grade glioma (LGG), lung adenocarcinoma (LUAD), lung us cell carcinoma (LUSC), ovarian serous cystadenocarcinoma (OV), pheochromocytoma and paraganglioma (PCPG), prostate adenocarcinoma (PRAD), skin cutaneous melanoma (SKCM), stomach adenocarcinoma (STAD), thyroid carcinoma (THCA), and uterine corpus endometrioid carcinoma (UCEC).
It was hypothesized that more passenger mutations will accumulate in cancer types with higher overall mutation rates, and the average number of altered genes per sample in each cancer type can be a surrogate for likelihood of passenger mutations in that cancer type. PGI was defined for each gene, X,, as a correlation between percentage sample with gene X; variant and average number of altered gene per sample in each cancer type. A higher PGI score indicated that a particular gene is more likely to acquire somatic mutations in the cancer types with higher overall mutation frequency. Passenger genes show strong linear relationship of the two variables, while weak associations were observed in canonical cancer genes such as TP53, P|K3CA and KRAS (. illustrates scatter plots for a fraction of patients with the gene t (y-axis) and e number of total mutated gene (x-axis) in each cancer type. The top row shows a strong linear relationship in the top passenger genes (MUC16 r=0.979; ADAMZ r=0.972; COL5A2 r=0.968), and the bottom row shows weak association ofthe 2 variables in cal cancer genes (TP53 r=0.301; P|K3CA r=0.120; KRAS r=0.222).
Genes ranked at the top ofthe PGI are enriched for gene families known for excessive passenger mutations, e.g., ely large proteins (>4,000 amino acids), genes spanning large genomic loci (>1Mb), genes with low sion level, and genes with late DNA replication time. A cumulative distribution function (CDF) of these gene families show a sharp d at PG|>O.7, while the driver genes in Catalogue of c Mutations in Cancer (COSMIC) Cancer Gene Census (CGC) are more uniformly distributed (. illustrates enrichment along the PGI scale for cancer driver genes and various other gene groups. The dotted lines (upper) show the fraction of genes at different PGI, and the vertical lines ) indicate the rank of individual genes. A two-sample orov-Smirnov test was used to examine the difference in gene distribution for each group, as compared to the cancer genes distribution. The mple Kolmogorov-Smirnov tests showed icant difference in the rank bution of passenger gene families as compared to that of CGC WO 60418 2018/051755 genes (p=8.3><10’19 for large proteins; p=2.9><10'12 for genomic locus >1Mb; p=6.4><10'3S for low expression; <10‘29 for late replication). Similar results were observed when samples were grouped by mutation rate (instead of cancer type) for computing PGI. While some CGC genes also possess high PGI score, they are not validated for their top altered TCGA cancer types. For instance, KDR (kinase insert domain receptor) has the t rate of on in melanoma (14% in SKCM) but KDR is only known for its causal implication in non-small—cell lung carcinoma and angiosarcoma. Similarly, we did not see any validated cases in the t altered cancer type for the top 30 CGC genes. In contrast, 16 out of the CGC driver genes with the lowest PGI are ted in their corresponding altered cancer type (. shows that low PGI CGC genes are more likely to be validated in the altered cancer type. shows the highest (left) and lowest (right) PGI CGC genes, and their corresponding cancer type with the highest percentage (>2%) of mutated sample. The acronyms marked with an asterisk are the cancer type validated by CGC for the gene. None of the cancer in the highest PGI CGC genes is validated, and 16/30 cancer types in the lowest PGI CGC genes are validated.
PGI was applied as a metric to select passenger genes and use the tumor mutational burden (TMB) of the selected passenger genes to stratify patient cohort that is more likely to respond to immunotherapy. To demonstrate this approach, local immune cytolytic activities and T-cell receptor (TCR) read count were used as the surrogate for immunogenicity, and tested if there is any immunogenicity difference between high and low TMB patients in TCGA data. For each patient, the TMB was computed in 3 ent approaches, namely (i) tional total TMB, (ii) TMB by driver genes, and (iii) TMB by passenger genes. To quantify the cytolytic activities, we adopted a simple RNA-based metric that based on gene expression level of two key cytolytic ors, me A (GZMA) and perforin (PRFl). The cytolytic activities were found significantly different (p<0.05 by Mann— y U test) between high and low passenger TMB patients in 7 different cancer types (colon adenocarcinoma, p<4.6x10'11; breast invasive carcinoma, p<5.0x10'4; lung adenocarcinoma, p<7.7x10'4; uterine corpus endometrioid carcinoma, p<9.9x10'4; cervical squamous cell carcinoma, p<2.2x10‘3; lung squamous cell carcinoma, p<5.7x10'3 ; prostate adenocarcinoma, p<2.1x10'2 ), and the differences are more significant as compared to those using total TMB and driver gene TMB in the corresponding cancer types ().
TCR is responsible for the recognition of peptide-MHC complexes and its diversity is directly associated to the number of foreign or d proteins, e.g. neo-antigens from cancer cells. TCRB repertoire analysis was performed using TCGA RNA-seq data, and compared TCRB read count between high and low passenger TMB ts. As shown in , the detected number of TCRB read count were significantly different n high and low passenger TMB patients in 8 different cancer types (uterine corpus endometrioid carcinoma, p<3.2><10'5; colon adenocarcinoma, p<4.5><10'6; cervical squamous cell carcinoma, p<2.4x10'3; breast invasive carcinoma, p<7.3><10'3; skin cutaneous ma, <10'3; lung adenocarcinoma, p<1.5><10'2; ovarian serous cystadenocarcinoma, p<2.7><10‘2; prostate adenocarcinoma, p<3.8><10'2). In agreement with the observation in cytolytic activities, the TCRB differences are more significant between the groups ated by ger TMB, as ed to those using total TMB and driver TMB.
Finally, tests were done to see if there is any survival advantage associated with TMB in TCGA data. In cervical and lung us cell carcinoma (CESC and LUSC), although not statistically significant, total TMB shows positive association trend with better survival e, while driver TMB is associated with worse prognosis (). illustrates clinical outcome of t cohorts segregated by mutation load of: (i) all genes, (ii) driver genes, and (iii) passenger genes in skin cutaneous melanoma (SKCM), cervical squamous cell carcinoma (CESC) and endocervical adenocarcinoma and lung squamous cell carcinoma (LUSC) yield significant survival differences only in patient cohorts segregated by passenger TMB but not total/driver TMB. SKCM shows significant difference in patient survival between high and low total/passenger TMB groups.
Only when the passenger TMB was used, the difference of the survival outcome between the high and low TMB t groups was statistically significant in both CESC and LUSC. In skin cutaneous melanoma (SKCM), patient stratification using passenger and total TMB both show similar significant separation in survival , indicating that there is very little or no driver gene mutation that strongly impact the genicity Suppression in melanoma. Using an independent dataset of CTLA—4 blockade in metastatic melanoma, 110 patients were segregated into two groups of equal size by mutation burden. Stratification using TMB of 200 passenger genes improved the al benefit rate of the selected patient group from a baseline of 24.55% to 36.36% (Fisher’s Exact Test p=0.0035). Patient stratification using the total TMB yields the same improvement in clinical benefit, further corroborate the observations in cytolytic activities, TCR detection, and al advantage for melanoma using TCGA data. shows the TMB of the patient cohort in an anti-PD1 phase 1 clinical study.
Closed s, closed squares, and closed les indicate patients with partial response (PR), stable disease (SD), and progressive e (PD) tively. Hollow shapes show data for individual patients, and solid shapes show the average in each PR/SD/PD groups.
Total TMBs are shown as the total number of mutated genes (left y—axis) and driver/passengerTMBs are shown in z-score (right y-axis). Both PR-vs-PD and PD+SD show statistically significant differences in the passenger TMB, invariantly of the number of top (50/100/1000) passenger genes used. PR group does not yield significant difference in the total or driver TM B.
Example 4 Passenger Gene Tumor Mutational Burden and Clinical therapy Response To evaluate the clinical response of various malignancies to immunotherapy, the somatic mutation data from phase 1 study of a monoclonal human dy to PD—1 (Programmed Death - 1) were used, as single y and in combination with other anti- cancer therapies. In total, clinical response data are available from 74 patients with advanced malignancies (n=8 with partial response, PR; n=29 with stable disease, SD; n=37 with progressive disease, PD). Total TMB is denoted as the total number of mutated genes, and driver/passenger TMBs are ented in z-scores in order to normalize for the total TMB of the patients. es are computed by comparing the number of mutated driver/passenger genes to the background distribution using randomly selected genes of equal size. Higher z-scores indicate higher mutation burden in the selected driver/passenger gene sets e the total TMB background. The total TMB and z-score ofdriverTMB do not differentiate PR from other patient groups, while the passenger TMB z—scores in PR patients are significantly higher as compared to those in PD or PD+SD patient groups.
Results are consistent in TMBs computed using top 50, 100, 500 (Fig. 12) and 1000 passenger genes.
