AI Technical Summary
Current anticancer treatments are inadequate for patient populations with biallelic ATM loss-of-function mutations or amplified CCNE1, and existing methods struggle to distinguish between biallelic and monoallelic mutations, as well as germline and somatic mutations.
The use of ATR inhibitors to treat cancers with biallelic ATM loss-of-function mutations, combined with methods to identify these mutations through next-generation sequencing techniques that analyze read counts and reference reads for SNVs, determine copy numbers, and apply segmentation analysis to distinguish between different mutation types.
This approach effectively targets and treats cancers with biallelic ATM loss-of-function mutations, providing targeted therapy and identifying mutations without requiring normal tissue samples, while being cost-efficient and robust against sample contamination.

Abstract
Description
[Technical field]
[0001] The present invention relates to methods of treating cancers with biallelic ATM loss of function using ATR inhibitors, and methods of identifying whether the mutation is biallelic or monoallelic, and whether it is germline or somatic. [Background technology]
[0002] ATR is essential for dividing cells and is therefore recognized as an important cancer target. ATR-deficient mice are embryonic lethal, whereas conditional ATR knockout adult mice are viable, affecting rapidly proliferating tissues and stem cell populations. Mouse embryonic stem cells lacking ATR divide only 1–2 times and then die. Interestingly, mice carrying a hypomorphic ATR mutation that reduced ATR expression to 10% of normal levels showed reduced H-rasG12D-induced tumor growth with minimal effects on proliferating normal cells, e.g., bone marrow or intestinal epithelial cells.
[0003] There is a need for new anti-cancer therapies, particularly those targeted at patient populations that are highly susceptible to such treatments. Summary of the Invention
[0004] Generally, the invention provides methods of treating cancer (e.g., those with biallelic ATM loss-of-function mutations or amplified CCNE1), inducing cell death in cancer cells (e.g., those with biallelic ATM loss-of-function mutations or amplified CCNE1), or identifying that a subject has biallelic loss-of-function of a target gene (e.g., ATM) or an amplified gene (e.g., CCNE1).
[0005] In one aspect, the present invention provides a method of treating a cancer harboring biallelic ATM loss-of-function mutations in a subject, comprising administering to a subject in need thereof an effective amount of an ATR inhibitor.
[0006] In another aspect, the present invention provides a method of treating cancer in a subject, comprising administering to a subject in need thereof an effective amount of an ATR inhibitor, wherein the cancer has been previously identified as having biallelic ATM loss-of-function mutations.
[0007] In yet another aspect, the invention provides a method of inducing cell death in a cancer cell harboring biallelic ATM loss-of-function mutations, comprising contacting the cell with an ATR inhibitor.

[0111] Generally, the present invention relates to methods of treating cancers that have biallelic ATM loss-of-function mutations, methods of inducing cell death in cancer cells that have biallelic ATM loss-of-function mutations, or methods of identifying target gene mutations (e.g., ATM).
[0112] The method of treating cancer or inducing cell death described herein typically utilizes ATR inhibitor.Cancer can be, for example, lung adenocarcinoma, adrenocortical carcinoma, invasive breast cancer (e.g., invasive breast cancer: LumB; invasive breast cancer: Her2; or invasive breast cancer: basal cell), pancreatic adenocarcinoma, bladder urothelial carcinoma, rectal adenocarcinoma, gastric adenocarcinoma, skin melanoma, colon adenocarcinoma, prostate adenocarcinoma, glioblastoma multiforme, esophageal carcinoma, uterine endometrial carcinoma, hepatocellular carcinoma, uterine endometrial carcinoma, lung squamous cell carcinoma, sarcoma, or ovarian serous cystadenocarcinoma.
[0113] Advantageously, the methods of the present invention use ATR inhibitors to treat cancers that have been found to be particularly responsive to ATR inhibition, these cancers harboring biallelic ATM loss-of-function mutations.
[0114] The method of the present invention also addresses the challenge of distinguishing between biallelic and uniallelic loss-of-function mutations, as well as between germline and somatic mutations. Advantageously, the method of the present invention explicitly considers sample purity, and is therefore substantially unaffected by contaminated samples. A further advantage of the method of the present invention is that it can utilize existing data from a panel of normal samples (normal non-cancerous tissues from a reference population) and does not require normal tissue samples from the subject.
[0115] Typically, subjects have a monoallelic germline (e.g., ATM) loss-of-function mutation and subsequently acquire a somatic loss-of-function mutation in the same gene (e.g., ATM). Thus, these subjects have biallelic (e.g., ATM) loss-of-function mutations.
[0116] Identification of biallelic loss of function A subject or its cancer cells may be identified as having biallelic loss of function of a gene, for example, using whole genome sequencing (WGS) or whole exome sequencing (WES). The method of the present invention addresses the need to identify biallelic loss-of-function mutations. Three exemplary structures of loss-of-function mutations are illustrated in Figures 1A-1C. Figures 1A and 1C show monoallelic loss-of-function mutations, and Figure 1B shows biallelic loss-of-function mutations. Typical next generation sequencing techniques used for cancer testing cannot distinguish between these structures. Immunohistochemistry (IHC) cannot distinguish between the biallelic mutation in Figure 1B and the monoallelic mutation in Figure 1C, resulting in apparent ATM protein loss. As described herein, a method involving identification of biallelic ATM loss-of-function mutations distinguishes between the biallelic mutation in Figure 1B and the monoallelic mutation in Figures 1A and 1C.
[0117] Advantageously, the methods presented herein identify that a subject or their cancer cells have biallelic loss of function of a gene with greater cost efficiency and targeted gene coverage than WGS and WES techniques.
[0118] Typically, the method of the present invention may include determining the total integer copy number of a locus segment and / or two integer allele-specific copy numbers of a locus segment in a target gene (e.g., ATM) region of a cancer cell or cancer cell from a subject from a read count and a reference read count of a plurality of SNVs, including homozygous single nucleotide variants (SNVs) and heterozygous SNVs, obtained from sequencing a sample containing cancer cells, wherein the cancer is identified as having a biallelic (e.g., ATM) loss-of-function mutation when at least one of the total integer copy number and the allele-specific copy number of the integer is 0. When the total integer copy number is 0, the detected mutation is a homozygous deletion. Thus, a homozygous deletion indicates a biallelic loss-of-function mutation of a target gene (e.g., ATM). When the total integer copy number is greater than 0 and the allele-specific copy number of the integer is 0 (e.g., in a locus where an ATM inactivating mutation is found), the detected mutation is a heterozygous loss. Thus, if the remaining alleles of the target gene (e.g., ATM) contain inactivating mutations, an integer allele-specific copy number of 0 indicates that the subject has both alleles of the target gene (e.g., ATM). For example, the determining step may include: determining a total copy number log ratio, an allele copy number log odds ratio, and a target coverage of heterozygous SNVs from the read counts and reference read counts of a plurality of SNVs, including homozygous SNVs and heterozygous SNVs, obtained from sequencing a sample containing cancer cells; segmenting the total copy number log ratio and the allele copy number log odds ratio; estimating the sample purity and sample ploidy of the cancer cells from the total copy number log ratio and the target coverage value; and generating an integer total copy number and two integer allele-specific copy numbers of the segment containing a plurality of heterozygous single nucleotide variants (SNVs) in the target gene region (e.g., ATM gene region) of the cancer cells from the target coverage value, sample purity, sample ploidy, total copy number log ratio, and allele copy number log odds ratio. Typically, cells derived from a subject are provided as a biopsy.Read counts can be obtained using next generation sequencing of cells in the sample.
[0119] Alternatively, the method of the present invention can utilize B allele frequency analysis to identify biallelic (e.g., ATM) loss of function. For example, the method can include determining a plurality of allele fractions of SNVs in a cancer cell or a target gene region (e.g., ATM gene region) from a subject, and segmenting the plurality of allele fractions to generate a plurality of constant allele fraction segments, where the cancer is identified as having a biallelic loss of function mutation (e.g., biallelic ATM loss of function mutation) if the target gene region (e.g., ATM gene region) includes a segmental locus lacking an SNV with an allele fraction of 0.05 to 0.95.
[0120] Among the methods described herein, the methods that utilize integer allele-specific copy numbers and integer total copy numbers are more advantageous than other methods because these methods are robust and can be used to process low purity samples.Furthermore, the methods described herein that utilize integer allele-specific copy numbers and integer total copy numbers can utilize existing data from a panel of normal samples from a reference population, and do not require normal tissue samples from the subject.Therefore, such methods allow for the determination of both allele loss-of-function mutations based on a single sample (e.g., biopsy) from the subject.
[0121] Target SNV The target SNVs used in the methods of the present invention can be selected from those known in the art according to several selection criteria specified below. SNVs can be searched, for example, at gnomad.broadinstitute.org.
[0122] The target SNV preferably has uniform coverage across samples. The target SNV has uniform coverage across samples if its average coverage across a panel of normal samples is at least 50x reads (e.g., at least 100x reads, at least 200x reads, at least 300x reads, at least 400x reads, or at least 500x reads). The panel of targeted SNVs may have an average coverage of at least 50x (e.g., at least 100x, at least 200x, at least 300x, at least 400x, at least 500x, at least 600x, at least 700x, at least 800x, at least 900x, or at least 1000x (e.g., 100x to 2500x, 200x to 2500x, 300x to 2500x, 400x to 2500x, 500x to 2500x, 600x to 2500x, 700x to 2500x, 800x to 2500x, 900x to 2500x, or 1000x to 2500x)) across a panel of normal samples. The panel of normal samples is derived from normal tissues of a reference population that is assumed to be chromosomally normal. A panel of normal samples has an SNV allele fraction of 0–0.1 for homozygous variants, 0.4–0.6 for heterozygous variants, and 0.9–1 for absent variants. Typically, a panel of normal samples is compiled from samples of the same tissue type as the subject samples.
[0123] The target SNV may be a high frequency SNV, for example, a high frequency SNV may have an allele frequency in humans greater than 33% (e.g., 33%-66%). Here, the assessment of the allele frequency in humans may be based on an SNV source, for example, Gnomad. The inbreeding coefficient of the reference population may be 0-0.2. Furthermore, the target SNV may be a close SNV, which is an SNV with uniform coverage located within the 3'-flanking sequence relative to the high frequency SNV, and the 3'-flanking sequence comprises a total of 300 contiguous nucleic acid bases.
[0124] The target SNV may have a 5'-flanking sequence of at least 20 contiguous nucleobases (e.g., 20-50 contiguous nucleobases, e.g., 50 contiguous nucleobases) that contains 25-75% GC content. Typically, the 5'-flanking sequence is unique (i.e., the sequence of 20 contiguous nucleobases is not found anywhere else in the target genome) and does not contain other SNVs.
[0125] The target SNV may be a clean SNV, which has a variant allele fraction (VAF) value within the ranges of 0-0.1, 0.4-0.6, and 0.9-1 in at least 95% of samples of a reference population.
[0126] Typically, the target SNV can be detected using a primer-based detection technique (e.g., next-generation sequencing technique). For multiple target SNVs, multiple primers can be designed using techniques and methods known in the art. When selecting target SNVs from a sequenced sample containing cancer cells from a subject, the target SNVs can be selected that are located within the 3'-flanking sequence relative to the binding sites of the multiple primers used. The 3'-flanking sequence is typically a sequence that contains 300 or less (e.g., 200 or less) consecutive nucleic acid bases in the 3' direction relative to the binding site of the primer used. The number of consecutive nucleic acid bases selected for the 3'-flanking sequence can be influenced by the level of DNA damage and the length of the DNA fragments of each patient sample. For example, when the average coverage is 100x or more (e.g., 200x or more), a 3'-flanking sequence with 200 or less consecutive nucleic acid bases can be used. For example, for samples with more than 17% of the input DNA fragments longer than 130 bp, a 3'-flanking sequence of 300 bp will be used, otherwise a 3'-flanking sequence of 200 bp will be used. As a general matter, the length of the 3'-flanking sequence can be adjusted taking into account the sequencing technique utilized for sample analysis and sample quality, with lower quality samples (i.e. samples with a high degree of DNA fragmentation) typically requiring the use of shorter 3'-flanking sequences and / or higher average coverage levels.
[0127] Advantageously, the method described herein does not require a normal tissue sample of the subject to determine whether the mutation is monoallelic or biallelic.Instead, the method described herein can utilize a reference population sample.For example, the reads from a panel of normal samples can be used instead of the normal reads in the BAM file.
[0128] Total copy number log ratio Total copy number log ratios (LogR) can be generated from the total read counts of the cancer vs. reference for all targeted SNVs with at least a minimum depth of coverage in the reference. LogR provides information on the total copy number ratio. Sequence read count information can be first parsed from the paired cancer and reference files. A normalization constant is calculated for each cancer / reference pair to correct for the total library size. Subsampling within 150-250 bp intervals may be applied to reduce hyper-segmentation of genomic regions with high density of SNVs. Specifically, the expected value of LogR can be expressed as:
[0129] E[logR]=log{(p1 * +p2 * ) / 2}+w(·)+λ In the formula, p1 * = p1 Φ + (1-Φ) and p2 * =p1·Φ+(1-Φ) is the parental copy number in the tumor sample resulting from a mixture of normal (1,1) and abnormal (p1,p2) copy number genotypes with a mixture ratio Φ. Φ is the cell fraction associated with the abnormal genotype and is a function of tumor purity and clonal frequency (in case of subclonal mutations). The term w(·) denotes lineage bias. GC content can be explicitly taken into account, using loess regression of logR against GC in 1 kb windows along the genome to estimate the effect of GC on read counts and subtracting it from logR. In addition, since LogR quantifies relative copy number, the constant λ is included in the conversion to absolute copy number.
[0130] For LogR generation, sequence read count information may be parsed from paired cancer and control BAM files. A normalization constant may be calculated for each cancer / control pair to correct for total library size. Subsampling within 150-250 bp intervals may be applied to reduce hypersegmentation of genomic regions with high density of SNVs.
[0131] Log odds ratio of allele copy numbers The log odds ratio (logOR) of the allelic copy number of the variant allele count and the reference allele count in cancer, which is an unbiased estimator of the allelic ratio: E[logOR] = [p1·Φ + (1 - Φ)] / [p2·Φ + (1 - Φ)] (where E[logOR] is the expected value of logOR, p1 is the parental copy number of the variant allele, p2 is the parental copy number of the allele from the other parent, and Φ is the cell fraction that is a function of tumor purity and clonal frequency (in the case of subclonal mutations)). In the absence of phase data, log 2 The squared logOR can be used to infer ([p1·Φ + (1 - Φ)] / [p2·Φ + (1 - Φ)]).
[0132] Joint segmentation Segmentation analysis can be used to identify genomic regions with a constant copy number using a change point detection method. Conventional methods (e.g., BIC-seq, exome CNV) typically perform one-dimensional segmentation using only logR or apply one-dimensional segmentation separately to logR and B allele frequency (BAF).
[0133] Preferably, the bivariate Hotelling T 2 Based on statistics, the circular binary segmentation (CBS) algorithm is used for joint segmentation of logR and logOR.

[0135] where T 1ij is the Mann-Whitney statistic that compares the observed logR set shown as {X 1k : i < k ≦ j} and its complement {X 1k : 1 < k ≦ i or j < k ≦ n}, and T 2ij is the Mann-Whitney statistic that compares the observed logR set shown as {X 2k : i < k ≦ j} and its complement {X 2k:1 < k ≦ i or j < k ≦ n}, which is the Mann-Whitney statistic for comparing the observed logOR sets shown as. In the above, c is a scale factor inversely proportional to the heterozygosity rate.
[0136] Here, when the maximum statistic is greater than a predetermined critical value, the change is stated, and the change point is estimated as i, j that maximizes the statistic. This approach repeatedly searches for change points between pairs of possible breakpoints and their complements to identify genomic regions with a certain allele-specific copy number. For each segment, the logR data is summarized using the median of the logR values

Number
[0140] is summarized by. logR is defined for all SNVs (loci of both homozygosity and heterozygosity), while logOR is defined only for heterozygous loci (het-loci or het-SNVs). Thus, in the integrated statistics, there may be an imbalance between the two. To address this problem, a weighting inversely proportional to the heterozygosity rate is introduced to increase the contribution of het-SNVs in subsequent segmentation analysis. Specifically, the scale factor c is introduced into the T 2 statistic. This is empirically
[0141]
number
[0142] where γ is the proportion of het-SNVs in the cancer cell sample. Weighting the contribution of the logOR of het-SNVs increases the ability to detect allelic imbalance in regions with low frequency of het-SNVs.
[0143] Alternatively, segmentation can be performed using, for example, a moving average method. Alternatively, the LogR and LogOR data can be divided into predefined short segments (based on the SNV loci).
[0144] After segmentation, the segments are clustered into groups of the same underlying genotype, which reduces the number of potential copy number and cell fraction states required for subsequent modeling.
[0145] Position deviation determination The LogR estimate is proportional to the absolute total copy number up to a position constant λ. For a diploid genome, logR=0 (library size normalized by logR) is the position of the 2-copy state. However, due to aneuploidy, the position may shift in tumors. Therefore, it is necessary to determine the 2-copy state in the tumor genome and quantify the position constant λ.
[0146] Copy number status can be indicated using total copy number and integer minor copy number (e.g., 1-0 indicates monosomy with total copy number 1 and minor copy number 0). Estimates of λ should correspond to the logR level at which the segment is in 2-1 (normal diploid) or 2-0 (LOH with no copy number change) state. In order to estimate λ, normal diploid segments need to be allelically balanced. Thus, candidate values of λ (λ c ), is close to zero

Additionally, for simplicity, higher order balanced gain states (6-3, 8-4, etc.) across large portions of the genome are not considered. Samples with segments of allelic balance in only a small portion of the target region are flagged and their λ estimates can be manually reviewed.

[0157] There exist values from which λc can be selected. Integer number of copies The integer allele-specific copy numbers (major and minor) and associated cell fractions for each segment cluster are estimated using a combination of parametric and nonparametric methods by modeling the expected values of logR and logOR given the total copy number (t) and each parental copy number (p1, p2) as a function of the cf parameter Φ, allowing both clonal and subclonal events to be modeled.

In practice, we assume equal variances and τ i 2 = τ 2 It is reasonable to set it as ∀i.
[0167] Furthermore, the logOR of SNV locus j in segment cluster i is X 2ij (X 2ij / σ ij ) 2 is assumed to follow a non-central chi-squared distribution: (X 2ij / σ ij ) 2 ~χ 2 (δ ijg ) In the formula, σ ij 2is the variance parameter of logOR, and δ ijg =μ ig 2 / σ ij 2 is the non-centrality parameter: μ ig 2 =log 2 ((m g Φ k +(1-Φ k )) / (p g Φ k +(1-Φ k ))) X 1ij and X 2ij Assuming that x, y, and y are independent random variables given the underlying copy number state g, the likelihood of the combined data can be written as:

This can be viewed as an estimation problem with the latent copy number states as missing data. The E-step of the EM procedure uses Bayes' theorem to calculate the posterior probability that copy number state g is assigned to segment cluster i given the parameter estimates at the tth iteration.

[0176] Cell fraction Φ k A clonal structure is imposed on the cell fraction parameter Φ 1 This is done in a sequential approach where the algorithm starts with a single clonal cluster (k=1) with k = 0. The method may then involve identifying segment clusters where the segment cluster-specific estimate is non-trivially (at least 0.05) lower than the clonally constrained estimate that does not lead to the best fit at k=1. These segment clusters with discordant cell fraction estimates are then analyzed to determine the lower cell fraction Φ 2 We form candidate subclonal clusters of events in and fit a model with optimized joint likelihood with k = 2.

[0180] are any subclonal clusters identified in the sample. Distinguishing between germline and somatic mutations The methods described herein can be used to identify target mutations as germline or somatic.
[0181] Using the methods described herein, identifying that the target mutation is a germline or somatic mutation can be achieved with or without the use of a matched normal sample from the subject (in addition to the sample containing cancer cells from the subject, e.g., biopsy).A matched normal sample from the same subject is a sample containing normal (non-cancerous) cells from the subject, e.g., a blood sample.
[0182] When a sample containing cancer cells from a subject (e.g., a biopsy from a subject) and a matched normal sample from the subject (e.g., a blood sample from a subject) are available, the methods described herein may include identifying a mutation in the matched normal sample from the subject. If the target mutation present in the cancer cells from the subject is identified in the matched normal sample, the target mutation is germline. If the target mutation present in the cancer cells from the subject is not identified in the matched normal sample, the target mutation is somatic.
[0183] For example, if a matched normal sample from the subject is not available, the methods described herein include: determining an observed allele fraction of a target mutation from read counts of a plurality of uniform coverage single nucleotide variants (SNVs), including homozygous and heterozygous uniform coverage SNVs, obtained from sequencing a sample comprising the cells; Determining the expected allele fraction (E[a]) of germline and somatic mutations, the allele fraction of germline mutations is E[a]=[(1-Φ) 1+Φ m cn ] / [(1-Φ) 2+Φ t tum ], and m cn is p1 or p2, and t tum is the total copy number of the locus in the tumor, and the allele fraction of the somatic mutation is m cn ≦min(p1,p2) for all enumerated E[a]=[Φ m cn ] / [(1-Φ) 2+Φ t tum ], wherein m cn is the variant allele copy number of the genomic region containing the target mutation, Φ is the cell fraction (used as a measure of sample purity), p1 is the parent copy number of the variant allele, and p2 is the parent copy number of the allele from the other parent; comparing the observed allele fraction to an expected allele fraction to identify the most likely germline and somatic mutations; and identifying the most likely of the germline and somatic mutations as the germline or somatic targeted mutation.
[0184] Mutant allele copy number (m cn ) is 1~t tum is an integer, and t tum is the total copy number of the allele of interest in the cancer cells from the subject. The comparing step can be performed using a Bayesian model comparison (Bayes factor).
[0185] This approach assumes that normal cells are diploid and that samples from subjects are not pure (Φ<1). As Φ approaches 1, germline and somatic mutations become indistinguishable in this approach in the absence of a matched normal sample from the subject.
[0186] Alternatively, for example, if a matched normal sample from the subject is not available and the sample containing cancer cells from the subject is not pure (Φ<0.9, or 90%), the methods described herein can be used to identify the target mutation as somatic if the observed allele fraction is outside the range of the expected allele fraction (without purity adjustment). For example, if the total copy number is 2, SNVs are expected to occur within the range of less than 10% (no homozygous SNVs), 40-60% (e.g., 45-55%) (heterozygous SNVs), and more than 90% (with homozygous SNVs) of the allele fraction (without purity adjustment), and therefore, if the observed allele fraction is outside the range of the expected allele fraction, the target mutation is somatic. If the observed allele fraction is within the range of the expected allele fraction, this identification approach cannot characterize the target mutation.
[0187] Identification of overexpression of target genes A subject or cancer cells thereof may be identified as having an amplification in a target gene if the total copy number is at least twice the sample ploidy, or if the total copy number is at least 2 units greater than the sample ploidy, using the methods described for identifying biallelic loss-of-function mutations, except that the cells are identified as having an amplification in the target gene.
[0188] Here, the total copy number is defined as t=p1+p2, or t=[2 (logR-λ+1) -2+2Φ] / Φ where p1*=p1·Φ+(1-Φ) and p2*=p1·Φ+(1-Φ) are the parental copy numbers in the tumor sample resulting from a mixture of normal (1,1) and abnormal (p1,p2) copy number genotypes with a mixture ratio Φ. The total copy number defined is therefore the unnormalized copy number. Φ is the cell fraction associated with the abnormal genotype, which is a function of the tumor purity and clonal frequency (in case of subclonal mutations). The term w(·) denotes lineage bias. GC content can be explicitly taken into account, using loess regression of logR against GC in 1 kb windows along the genome to estimate the effect of GC on read counts and subtracting it from logR. In addition, since LogR quantifies relative copy number, the constant λ is included in the conversion of absolute copy number.
[0189] For LogR generation, sequence read count information may be parsed from paired cancer and control BAM files. A normalization constant may be calculated for each cancer / control pair to correct for total library size. Subsampling within 150-250 bp intervals may be applied to reduce hypersegmentation of genomic regions with high density of SNVs.
[0190] Accordingly, the present invention provides a method for identifying cells derived from a subject that have amplification in a target gene, comprising the steps of: determining a total copy number and a sample ploidy of a locus segment within a target genomic region of cells from a subject from read counts of a plurality of uniform coverage single nucleotide variants (SNVs), including homozygous and heterozygous uniform coverage SNVs, and reference read counts obtained from sequencing a sample comprising cells, wherein the target genomic region comprises a mutation, and the reference read counts are derived from a panel of normal samples; Here, methods are provided in which a cell is identified as having amplification in a target gene if the total copy number is at least twice (e.g., at least 2x) the sample ploidy, or if the total copy number is at least 2 (e.g., at least 3) greater than the sample ploidy.
[0191] In some embodiments, the determining step comprises: determining a total copy number log ratio of the SNVs and a target coverage value from the read counts and the reference read counts; Segmenting the total copy number log ratio; Estimating the sample purity and sample ploidy of the cells from the total copy number log ratio and the target coverage value; and generating a total copy number of the locus segment within the target gene region from the target coverage value, the sample purity, the sample ploidy, and the total copy number log ratio.
[0192] Total copy number can be normalized for ploidy as follows: n =2·t / p2(where t n is the normalized total copy number, t is the non-normalized copy number, and p2 is as defined above).
[0193] Identification of biallelic ATM loss-of-function mutations Thus, the methods described herein may include identifying cancers that have biallelic ATM loss-of-function mutations using the techniques described above.
[0194] Identification of CCNE1 overexpression Thus, the methods described herein may include a step of identifying cancers in which CCNE1 is amplified using the techniques described above.
[0195] Detection of SNVs Detection techniques for evaluating nucleic acid for the presence of SNV include procedures well known in the field of molecular genetics. Many, but not all, of these methods involve nucleic acid amplification. Sufficient guidelines for carrying out amplification are provided in the art. Exemplary references include manuals such as PCR Technology: Principles and Applications for DNA Amplification (ed. H.A. Erlich, Freeman Press, NY, NY, 1992); PCR Protocols: A Guide to Methods and Applications (eds. Innis, et al., Academic Press, San Diego, Calif., 1990); Current Protocols in Molecular Biology, Ausubel, 1994-1999 (including supplements up to April 2004); Sambrook & Russell, Molecular Cloning, A Laboratory Manual (3rd Ed, 2001). A general method for detecting single base variants is disclosed in Single Nucleotide Variants: Methods and Protocols, Pui-Yan Kwok, ed., 2003, Humana Press. SNV detection methods often employ labeled oligonucleotides. Oligonucleotides can be labeled by incorporating a label that can be detected by spectroscopic, photochemical, biochemical, immunochemical, or chemical means. Useful labels include fluorescent dyes, radioactive labels such as 32P, electron-dense reagents, enzymes such as peroxidase or alkaline phosphatase, biotin, or haptens and proteins that can be used against antisera or monoclonal antibodies. Labeling techniques are well known in the art (see, for example, Current Protocols in Molecular Biolog, supra; Sambrook & Russell, supra).
[0196] The methods typically employ a PCR step, although other amplification protocols may be used. Suitable amplification methods include the ligase chain reaction (see, e.g., Wu & Wallace, Genomics 4:560-569, 1988); strand displacement assays (see, e.g., Walker et al., Proc. Natl. Acad. Sci. USA 89:392-396, 1992; U.S. Pat. No. 5,455,166); as well as several transcription-based amplification systems, such as those described in U.S. Pat. Nos. 5,437,990; 5,409,818; and 5,399,491; the transcription amplification system (TAS) (Kwoh et al., Proc. Natl. Acad. Sci. USA 86:1173-1177, 1989); and self-sustained sequence replication (3SR) (Guatelli et al., Proc. Natl. Acad. Sci. USA 87:1874-1878, 1990; WO92 / 08800). Alternatively, methods for amplifying the probe to detectable levels, such as Qβ-replicase amplification, can be used (Kramer & Lizardi, Nature 339:401-402, 1989; Lomeli et al., Clin. Chem. 35:1826-1831, 1989). A review of known amplification methods is provided, for example, by Abramson and Myers in Curr. Op Biotechnol. 4:41-47, 1993.
[0197] Detection of individual genotypes, haplotypes, SNVs, microsatellites, or other variants can be performed using oligonucleotide primers and / or probes. Oligonucleotides can be prepared by any suitable method, usually chemical synthesis. Oligonucleotides can be synthesized using commercially available reagents and equipment. Alternatively, they can be purchased commercially. Methods for synthesizing oligonucleotides are well known in the art (see, for example, Narang et al., Meth. Enzymol. 68:90-99, 1979; Brown et al., Meth. Enzymol. 68:109-151, 1979; Beaucage et al., Tetrahedron Lett. 22:1859-1862, 1981; and the solid-phase method of U.S. Pat. No. 4,458,066). In addition, modifications of the above-mentioned synthesis methods can be used to affect enzyme behavior on synthesized oligonucleotides in a desired way. For example, incorporation of modified phosphodiester linkages (e.g., phosphorothioates, methylphosphonates, phosphoamidates, or boranophosphates) or linkages other than phosphorous derivatives into oligonucleotides can be used to prevent cleavage at selected sites. In addition, the use of 2'-amino modified sugars tends to favor displacement over digestion of the oligonucleotide when hybridized to a nucleic acid that is also a template for the synthesis of a new nucleic acid strand.
[0198] The genotype of an individual can be determined using many detection methods well known in the art. Most assays require one of several general protocols: hybridization using allele-specific oligonucleotides, primer extension, allele-specific ligation, sequencing, or electrophoretic separation techniques, such as single-stranded conformation variants (SSCP) and heteroduplex analysis. Exemplary assays include 5'-nuclease assays, template-directed dye terminator incorporation, molecular beacon allele-specific oligonucleotide assays, single-base extension assays, and SNV scoring by real-time pyrophosphate sequences. Analysis of the amplified sequences can be performed using a variety of techniques, such as microchips, fluorescence polarization assays, and MALDI-TOF (matrix-assisted laser desorption / ionization time-of-flight) mass spectrometry. Two methods that can be used as well are the assay based on invasive cleavage by Flap nucleases and the methodology employing padlock probes.
[0199] The determination of the presence or absence of a particular allele is generally carried out by analyzing a nucleic acid sample obtained from an individual to be analyzed.In many cases, the nucleic acid sample comprises genomic DNA.The genomic DNA is typically obtained from a blood sample, but may also be obtained from other cells or tissues.
[0200] It is also possible to analyze RNA samples for the presence of polymorphic alleles.For example, mRNA can be used to determine the genotype of an individual at one or more polymorphic sites.In this case, a nucleic acid sample is obtained from a cell in which the target nucleic acid is expressed, for example, an adipocyte.Such analysis can be carried out by first reverse transcribing the target RNA, for example, using viral reverse transcriptase, and then amplifying the obtained cDNA, or by combining the use of high-temperature reverse transcription polymerase chain reaction (RT-PCR) as described in U.S. Patent Nos. 5,310,652; 5,322,770; 5,561,058; 5,641,864; and 5,693,517.
[0201] A brief description of methodologies commonly used in the analysis of nucleic acid samples to detect SNVs is provided below. However, any method known in the art can be used in the present invention to detect the presence of a single base substitution.
[0202] Allele-specific hybridization Allele-specific hybridization, also commonly referred to as allele-specific oligonucleotide hybridization (ASO) (e.g., Stoneking et al., Am. J. Hum. Genet. 48:70-382, 1991; Saiki et al., Nature 324, 163-166, 1986; EP 235, 726; and WO 89 / 11548), relies on distinguishing between two DNA molecules that differ by only one base by hybridizing an oligonucleotide probe specific for one of the variants to an amplification product resulting from amplification of a nucleic acid sample. This method typically employs short, e.g., 15-20 base long, oligonucleotides. The probes are designed to differentially hybridize with one variant from another. Principles and guidelines for designing such probes are available in the art, e.g., in the references cited herein. Hybridization conditions must be sufficiently stringent so that there is a significant difference in hybridization intensity between the alleles, resulting in an essentially binary response, with the probe hybridizing to only one of the alleles. Some probes are designed to hybridize to a segment of target DNA such that the polymorphic site is aligned with the central position of the probe (e.g., the 7th position for a 15-base oligonucleotide; the 8th or 9th position for a 16-base oligonucleotide), although this design is not required.
[0203] The amount and / or presence of an allele is determined by measuring the amount of allele-specific oligonucleotide hybridized to a sample. Typically, the oligonucleotide is labeled with a label, such as a fluorescent label. For example, the allele-specific oligonucleotide is applied to an immobilized oligonucleotide representing an SNV sequence. After stringent hybridization and washing conditions, the fluorescence intensity of each SNV oligonucleotide is measured.
[0204] In one embodiment, the nucleotides present at the polymorphic site are identified by hybridization under sequence-specific hybridization conditions with an oligonucleotide probe or primer that is exactly complementary to one of the polymorphic alleles in the region encompassing the polymorphic site. The hybridization sequence of the probe or primer and the sequence-specific hybridization conditions are selected such that a single mismatch at the polymorphic site sufficiently destabilizes the hybridization duplex such that a hybridization duplex is not substantially formed. Therefore, under sequence-specific hybridization conditions, a stable duplex is formed only between the probe or primer and the exactly complementary allele sequence. Thus, oligonucleotides of about 10 to about 35 nucleotides in length, usually about 15 to about 35 nucleotides in length, that are exactly complementary to the allele sequence in the region encompassing the polymorphic site, are within the scope of the present invention.
[0205] In an alternative embodiment, the nucleotide present at the polymorphic site is identified by hybridization under sufficiently stringent hybridization conditions using an oligonucleotide that is substantially complementary to one of the SNV alleles in the region encompassing the polymorphic site and is exactly complementary to the allele at the polymorphic site.Since the mismatch occurring at the non-polymorphic site is a mismatch with both allele sequences, the difference between the number of mismatches in the duplex formed with the target allele sequence and the number of mismatches in the duplex formed with the corresponding non-target allele sequence is the same as when an oligonucleotide that is exactly complementary to the target allele sequence is used.In this embodiment, the hybridization conditions are sufficiently relaxed to allow the formation of a stable duplex with the target sequence while maintaining sufficient stringency to exclude the formation of a stable duplex with non-target sequences.Under such sufficiently stringent hybridization conditions, a stable duplex is formed only between the probe or primer and the target allele. Thus, oligonucleotides from about 10 to about 35 nucleotides in length, typically from about 15 to about 35 nucleotides in length, that are substantially complementary to the allelic sequence in the region encompassing the polymorphic site and that are exactly complementary to the allelic sequence at the polymorphic site are within the scope of the present invention.
[0206] In assay formats where optimization of hybridization conditions is limited, the use of substantially complementary oligonucleotides rather than exactly complementary oligonucleotides may be desirable. For example, in a typical multi-target immobilized oligonucleotide assay format, a probe or primer for each target is immobilized on a single solid support. Hybridization is performed simultaneously by contacting the solid support with a solution containing the target DNA. Since all hybridizations are performed under identical conditions, hybridization conditions cannot be optimized separately for each probe or primer. If the assay format does not allow adjustment of hybridization conditions, the incorporation of mismatches into the probe or primer can be used to adjust duplex stability. The effect of the particular mismatch introduced on duplex stability is well known, and duplex stability can be routinely estimated or empirically determined as described above. Suitable hybridization conditions depend on the exact size and sequence of the probe or primer, and can be empirically selected using the guidelines provided herein and well known in the art. The use of oligonucleotide probes or primers to detect single base pair differences in sequence is described, for example, in Conner et al., Proc. Natl. Acad. Sci. USA 80:278-282, 1983, and U.S. Pat. Nos. 5,468,613 and 5,604,099, each of which is incorporated herein by reference.
[0207] The proportional change in stability between a perfectly matched hybridization duplex and a single base mismatched hybridization duplex depends on the length of the hybridized oligonucleotide. The duplex formed with the shorter probe sequence is proportionally more destabilized by the presence of mismatches. Oligonucleotides of about 15 to about 35 nucleotides in length are often used for sequence-specific detection. Furthermore, because the ends of the hybridized oligonucleotide undergo continuous random separation and reannealing by thermal energy, mismatches at either end do not destabilize the hybridization duplex as much as mismatches occurring internally. To identify a single base pair change in a target sequence, the probe sequence hybridized to the target sequence is selected such that the polymorphic site is present in the internal region of the probe.
[0208] The above criteria for selecting the probe sequence that hybridizes to specific alleles are applied to the hybridization region of the probe, i.e., the part of the probe that is involved in hybridization with the target sequence.The probe can be bound to additional nucleic acid sequences, such as poly-T tails, that are used for immobilizing the probe, without significantly changing the hybridization properties of the probe.Those skilled in the art will recognize that when used in the present method, the probe that is bound to additional nucleic acid sequences that are not complementary to the target sequence and therefore are not involved in hybridization is essentially equivalent to a non-bound probe.
[0209] Suitable assay formats for detecting hybrids formed between a probe and a target nucleic acid sequence in a sample are known in the art and include immobilized target (dot blot) and immobilized probe (reverse dot blot or line blot) assay formats. Dot blot and reverse dot blot assay formats are described in U.S. Patent Nos. 5,310,893; 5,451,512; 5,468,613; and 5,604,099, each of which is incorporated herein by reference.
[0210] In the dot blot format, amplified target DNA is immobilized on a solid support such as a nylon membrane, the membrane-target complex is incubated with a labeled probe under suitable hybridization conditions, unhybridized probe is removed by washing under suitable stringency conditions, and the membrane is monitored for the presence of bound probe.
[0211] In the reverse dot blot (or line blot) format, the probe is immobilized on a solid support such as a nylon membrane or a microtiter plate. Typically, the target DNA is labeled by incorporation of a labeled primer during amplification. One or both of the primers can be labeled. The membrane-probe complex is incubated with the labeled amplified target DNA under suitable hybridization conditions, unhybridized target DNA is removed by washing under suitable stringent conditions, and the membrane is monitored for the presence of bound target DNA. A reverse line blot detection assay is described in the Examples.
[0212] In many cases, an allele-specific probe specific for one variant mutation and an allele-specific probe for the other variant mutation are used together. In some embodiments, the probe is fixed to a solid support, and the target sequence in an individual is analyzed using both probes simultaneously. Examples of nucleic acid arrays are described in WO95 / 11995. The same array or different arrays can be used to analyze characterized variants. WO95 / 11995 also describes subarrays that are optimized for detecting precharacterized variant types. Such subarrays can be used to detect the presence of variants described herein.
[0213] Allele-specific primers Variants can also be detected using allele-specific amplification or primer extension methods. These reactions typically involve the use of primers designed to specifically target variants via a mismatch at the 3' end of the primer. The presence of a mismatch affects the ability of the polymerase to extend the primer if the polymerase does not have error-correcting activity. For example, to detect an allele sequence using allele-specific amplification or extension-based methods, a primer complementary to one allele of the variant is designed such that the 3' terminal nucleotide hybridizes at the polymorphic position. The presence of a particular allele can be determined by the ability of the primer to initiate extension. If the 3' end is mismatched, extension is inhibited.
[0214] In some embodiments, the primer is used together with a second primer in the amplification reaction. The second primer hybridizes at a site unrelated to the polymorphic position. Amplification proceeds from the two primers, resulting in a detectable product that indicates the presence of a specific allele type. Methods based on allele-specific amplification or extension are described, for example, in WO93 / 22456; U.S. Patent No. 5,137,806; U.S. Patent No. 5,595,890; U.S. Patent No. 5,639,611; and U.S. Patent No. 4,851,331.
[0215] Using allele-specific amplification-based genotyping, allele identification is simply a matter of detecting the presence or absence of an amplified target sequence. Methods for detecting an amplified target sequence are well known in the art. For example, the presence of a nucleic acid can often be detected using gel electrophoresis and probe hybridization assays as described.
[0216] In an alternative probeless method, amplified nucleic acid is detected by monitoring the increase in the total amount of double-stranded DNA in the reaction mixture, as described, for example, in U.S. Patent No. 5,994,056 and European Patent Publications Nos. 487,218 and 512,334. Detection of double-stranded target DNA relies on the increased tendency of various DNA binding dyes, such as SYBR Green, to bind to double-stranded DNA.
[0217] As will be understood by those skilled in the art, allele-specific amplification methods can be carried out in a reaction that employs multiple allele-specific primers that target specific alleles.The primers for such multiplex applications are generally labeled with distinguishable labels or selected so that the amplification products generated from alleles can be distinguished by size.Therefore, for example, one round of amplification can be used to identify both alleles in a single sample by gel analysis of the amplification products.
[0218] As with the allele-specific probes, the allele-specific oligonucleotide primers may be exactly complementary to one of the polymorphic alleles in the hybridization region, or may have some mismatches at positions other than the 3' end of the oligonucleotide, which mismatches are present at non-polymorphic sites in both allele sequences.
[0219] Detectable Probes 5'-Nuclease Assay Probe Genotyping can also be performed using "TaqMan®" or "5'-nuclease assays", for example, as described in U.S. Pat. Nos. 5,210,015; 5,487,972; and 5,804,375; and Holland et al., Proc. Natl. Acad. Sci. USA 88:7276-72801988. In the TaqMan® assay, a labeled detection probe that hybridizes within the amplified region is added during the amplification reaction. The probe is modified so that it does not act as a primer for DNA synthesis. Amplification is performed using a DNA polymerase with 5'→3' exonuclease activity. During each synthesis step of amplification, any probe that hybridizes to the target nucleic acid downstream from the primer being extended is degraded by the 5'→3' exonuclease activity of the DNA polymerase. Thus, synthesis of a new target strand also results in degradation of the probe, and accumulation of degradation products is indicative of synthesis of the target sequence.
[0220] The hybridization probe may be an allele-specific probe that distinguishes between SNV alleles. Alternatively, the method may be performed using an allele-specific primer and a labeled probe that binds to the amplification product.
[0221] Any method suitable for detecting degradation products can be used in the 5'-nuclease assay. Often, the detection probe is labeled with two fluorescent dyes, one capable of quenching the fluorescence of the other dye. A dye is attached to the probe, usually one at the 5' end and the other at an internal position, so that quenching occurs when the probe is unhybridized and cleavage of the probe occurs between the two dyes due to the 5'→3' exonuclease activity of DNA polymerase. Amplification cleaves the probe between the dyes, removing the quenching and increasing the observable fluorescence from the originally quenched dye. The accumulation of degradation products is monitored by measuring the increase in reaction fluorescence. U.S. Pat. Nos. 5,491,063 and 5,571,673 describe alternative methods for detecting the degradation of the probe that occurs with amplification, both of which are incorporated herein by reference.
[0222] Secondary structure probes Probes detectable by changes in secondary structure are also suitable for detecting variants, including SNVs. Exemplary secondary structure or stem-loop structure probes include molecular beacons or Scorpion® primers / probes. Molecular beacon probes are single-stranded oligonucleic acid probes that can typically form a hairpin structure with a fluorophore and a quencher on either side of the oligonucleotide. Short complementary sequences at both ends of the probe allow the formation of an intramolecular stem, which allows the fluorophore and quencher to be in close proximity. The loop portion of the molecular beacon is complementary to the target nucleic acid of interest. When the probe binds to its target nucleic acid of interest, a hybrid is formed and the stem is forced apart. This causes a conformational change that separates the fluorophore and quencher from each other, resulting in a stronger fluorescent signal. However, molecular beacon probes are extremely sensitive to slight sequence changes in the probe target (Tyagi and Kramer, Nat. Biotechnol. Vol. 14, pages 303-308, 1996; Tyagi et al., Nat. Biotech, Vol. 16, pages 49-53, 1998; Piatek et al., Nat Biotechnol, 16:359-363 (1998); Marras et al., Genetic Analysis: Biomolecular Engineering, Vol 14, pages 151-156 (1999); Tapp I. et al, BioTechniques. Vol 28, pages 732-738, 2000). Scorpion® primer / probes contain a stem-loop structure probe covalently attached to the primer.
[0223] Electrophoresis Amplification products generated using the polymerase chain reaction can be analyzed by the use of denaturing gradient gel electrophoresis. Different alleles can be identified based on differences in sequence-dependent melting properties and electrophoretic migration of DNA in solution (see, e.g., Erlich, ed., PCR Technology: Principles and Applications for DNA Amplification, WH Freeman and Co, New York, 1992, Chapter 7).
[0224] Microsatellite variants can be distinguished using capillary electrophoresis. Capillary electrophoresis can easily identify the number of repeats of a particular microsatellite allele. The application of capillary electrophoresis to DNA variant analysis is well known in the art (see, for example, Szantai, et al, J Chromatogr A. 1079(1-2):41-49, 2005; Bjorheim and Ekstrom, Electrophoresis 26(13):2520-2530, 2005 and Mitchelson, Mol Biotechnol. 24(1):41 68, 2003).
[0225] Single-strand conformation polymorphism analysis Alleles of a target sequence can be distinguished using single-strand conformation polymorphism analysis, which identifies base differences by changes in the electrophoretic mobility of single-stranded PCR products, for example, as described in Orita et al., Proc. Natl. Acad. Sci. USA 86(8), 2766-2770, 1989. Amplified PCR products can be generated as described above and heated or otherwise denatured to form single-stranded amplification products. Single-stranded nucleic acids can refold or form secondary structures that depend in part on the base sequence. Differences in the electrophoretic mobility of single-stranded amplification products can be related to differences in base sequence between alleles of the target.
[0226] DNA sequencing and single base extension SNVs can also be detected by direct sequencing, including methods based on dideoxy sequencing and others such as Maxam-Gilbert sequences (see, e.g., Sambrook and Russell, supra).
[0227] Other detection methods include Pyrosequencing™ of oligonucleotide-length products. Such methods often utilize amplification techniques such as PCR. For example, in pyrosequencing, a sequencing primer is hybridized to a PCR-amplified single-stranded DNA template and incubated with the enzymes DNA polymerase, ATP sulfurylase, luciferase, and apyrase, and the substrates adenosine 5′ phosphosulfate (APS) and luciferin. The first of four deoxynucleotide triphosphates (dNTPs) is added to the reaction. DNA polymerase catalyzes the incorporation of the deoxynucleotide triphosphate into the DNA strand if it is complementary to a base in the template strand. Each incorporation event is accompanied by the release of pyrophosphate (PPi) in an amount equimolar to the amount of incorporated nucleotide. ATP sulfurylase quantitatively converts PPi to ATP in the presence of adenosine 5′ phosphosulfate. This ATP drives the luciferase-mediated conversion of luciferin to oxyluciferin, producing visible light proportional to the amount of ATP. The light produced in the luciferase-catalyzed reaction is detected by a charge-coupled device (CCD) camera and displayed as a peak on a Pyrogram™. Each light signal is proportional to the number of nucleotides incorporated. Apyrase, a nucleolytic enzyme, continuously degrades unincorporated dNTPs and excess ATP. Once degradation is complete, another dNTP is added.
[0228] Another similar method for characterizing SNVs does not require the use of full PCR, but typically uses only primer extension with a single fluorescently labeled dideoxyribonucleic acid molecule (ddNTP) complementary to the nucleotide to be interrogated. The nucleotide at the polymorphic site can be identified through detection of a primer that is extended by a single base and fluorescently labeled (e.g., Kobayashi et al, Mol. Cell. Probes, 9:175-182, 1995).
[0229] Furthermore, SNVs can be determined from the analysis (e.g., computational analysis) of data obtained from next-generation sequencing (NGS) experiments (Buermans and Dunnen. Biochimica et Biophysica Acta. 1842:1932-1941, 2014). Sequencing can be performed by various systems currently available, such as, but not limited to, sequencing systems by ILLUMINA®, Pacific Biosciences (PACBIO®), Oxford NANOPORE®, or Life Technologies (ION TORRENT®). Methods, reagents, and equipment for performing these different sequencing systems are available from the respective manufacturers. Alternatively or additionally, sequencing may be performed using nucleic acid amplification, polymerase chain reaction (PCR) (e.g., digital PCR, quantitative PCR, or real-time PCR), or isothermal amplification. Such systems may provide a plurality of raw genetic data corresponding to the genetic information of a subject (e.g., a human) generated by the system from a sample provided by the subject. In some instances, such systems provide sequencing reads, which may include a string of nucleobases that corresponds to the sequence of the sequenced nucleic acid molecule.
[0230] SNVs can be identified from data generated by NGS experiments by comparing the occurrence of different nucleic acid base pairs at the same locus in multiple samples. Due to errors that occur in NGS sequencing, probabilistic models (e.g., Bayesian models) are often used to distinguish and correct for read errors and true SNVs. A wide variety of methods and algorithms have been developed to detect SNVs from NGS data (see, e.g., Nielsen et al. Nat. Rev. Genet. 12(6):443-451, 2011; Bansal, Bioinformatics. 26(12):i318-i324, 2010; Roth et al. Bioinformatics. 28(7):907-913, 2012; You et al. Bioinformatics. 28(5):643-650, 2012; Li et al., Genome Res. 19(6):1124-1132, 2009; Abecasis et al. Nature. 467(7319):1061-1073, 2010; Larson et al. Bioinformatics. 28(3):311-317, 2012). Resources for identifying SNVs found in the human genome include databases of sequenced genomes (e.g., gnomAD, Bravo, ClinVar, 1000 Genome Project, and TopMed) and databases of identified SNVs (e.g., dbSNP, HapMap, Biomart, SPSmart, and Genome Variation Server (GVS)).

[0387] The compounds described herein may also be used in the form of free base, salts, zwitterions, solvates, or as prodrugs or pharmaceutical compositions thereof. All forms are within the scope of the present invention. The compounds, their salts, zwitterions, solvates, prodrugs, or pharmaceutical compositions may be administered to patients in various forms depending on the selected route of administration, as will be understood by those skilled in the art. The compounds used in the methods described herein may be administered, for example, by oral, parenteral, oral mucosal, sublingual, nasal, rectal, patch, pump, or transdermal administration, and pharmaceutical compositions may be formulated accordingly. Parenteral administration includes intravenous, intraperitoneal, subcutaneous, intramuscular, transepithelial, nasal, pulmonary, intrathecal, rectal, and topical modes of administration. Parenteral administration may be by continuous infusion over a selected period of time.
[0388] For use in humans, the compounds of the present invention can be administered alone or in admixture with a pharmaceutical carrier selected with respect to the intended route of administration and standard pharmaceutical practice. Thus, pharmaceutical compositions for use according to the present invention can be formulated in a conventional manner using one or more physiologically acceptable carriers, including excipients and auxiliaries, that facilitate the processing of the compounds of the present invention into pharma- ceutical preparations that can be used.
[0389] The present invention also includes pharmaceutical compositions that may contain one or more pharma- ceutically acceptable carriers. In making pharmaceutical compositions of the present invention, active ingredients are typically mixed with or diluted by excipients, or enclosed within such carriers, for example in the form of capsules, sachets, paper, or other containers. When excipients function as diluents, they can be solid, semi-solid, or liquid materials (e.g., normal saline), and act as vehicles, carriers, or media for the active ingredients. Thus, the compositions can be in the form of tablets, powders, lozenges, sachets, cachets, elixirs, suspensions, emulsions, solutions, syrups, and soft and hard gelatin capsules. As known in the art, the type of diluent can vary depending on the intended route of administration. The resulting compositions can include additional agents, for example, preservatives.
[0390] Excipient or carrier is selected based on the formulation and route of administration. Suitable pharmaceutical carriers and pharmaceutical requirements for use in pharmaceutical formulations are described in Remington: The Science and Practice of Pharmacy, 21st Ed., Gennaro, Ed., Lippincott Williams & Wilkins (2005), well-known references in the field, and USP / NF (United States Pharmacopeia and the National Formulary). Examples of suitable excipients are lactose, dextrose, sucrose, sorbitol, mannitol, starch, gum arabic, calcium phosphate, alginate, tragacanth, gelatin, calcium silicate, microcrystalline cellulose, polyvinylpyrrolidone, cellulose, water, syrup, and methylcellulose. The formulation may further include lubricants such as talc, magnesium stearate, and mineral oil; wetting agents; emulsifying and suspending agents; preservatives such as methyl benzoate and propyl hydroxybenzoate; sweeteners; and flavoring agents. Other exemplary excipients are described in Handbook of Pharmaceutical Excipients, 6th Edition, Rowe et al., Eds., Pharmaceutical Press (2009).
[0391] These pharmaceutical compositions can be manufactured in a conventional manner, for example, by conventional mixing, dissolving, granulating, sugar-coating, levigating, emulsifying, encapsulating, encapsulating or lyophilizing processes. Methods for preparing formulations well known in the art can be found, for example, in Remington: The Science and Practice of Pharmacy, 21st Ed., Gennaro, Ed., Lippincott Williams & Wilkins (2005), and Encyclopedia of Pharmaceutical Technology, eds. J. Swarbrick and JC Boylan, 1988-1999, Marcel Dekker, New York. Appropriate formulations depend on the route of administration selected. The formulation and preparation of such compositions are well known to those skilled in the art of pharmaceutical formulations. When preparing formulations, the active compound can be milled and then mixed with other ingredients to obtain a suitable particle size. If the active compound is substantially insoluble, it can be milled to a particle size of less than 200 mesh. If the active compound is substantially water soluble, the particle size can be adjusted by milling to provide a substantially uniform distribution in the formulation, eg, 40 mesh.

Powders, granules, and pellets may be prepared in a conventional manner using the ingredients of the above-mentioned tablets and capsules, for example, using a mixer, fluid bed equipment, or spray drying equipment.
[0399] Controlled release compositions for oral use can be configured to release the active drug by controlling the dissolution and / or diffusion of the active drug substance. Any of a number of strategies can be implemented to obtain controlled release and a target plasma concentration versus time profile. In one example, controlled release is obtained by appropriate selection of various formulation parameters and ingredients, including, for example, various types of controlled release compositions and coatings.

[0407] The following examples are intended to illustrate the invention without, however, limiting it in any way. EXAMPLES
[0408] Example 1. Design of SNV panel version 1 To quantify genetic alterations in the ATM gene, an SNV panel was designed based on Anchored Multiplex PCR (AMP™) technology. Gene-specific primers were designed to amplify genomic regions of interest using AMP chemistry.
[0409] Gene-specific primers were designed for up to 30 single nucleotide variants (SNVs) occurring in 20–80% of the global population (as defined in the gnomAD database v.2.1.1) for ATM targets.
[0410] Samples were assessed for ploidy and chromosome arm losses using gene-specific primers designed against 1000 SNVs randomly distributed across the genome. Example 2. Performance evaluation of SNV Panel version 1 for whole genome sequencing The SNV panel designed according to the process outlined in Example 1 can quantify ATM loss of heterozygosity and copy number deletion. Furthermore, the SNV panel design shows complete exon coverage and also provides genome-wide SNV quantification of purity and ploidy calls. The performance of the SNV panel was evaluated against whole genome sequencing (WGS) of three samples from subjects with various cancers. Specifically, the three subjects were a 46-year-old woman with papillary serous carcinoma, a 62-year-old woman with pancreatic ductal adenocarcinoma, and a 72-year-old woman with ER-, PR-, HER2- metastatic breast cancer.
[0411] To prepare each SNV panel sample, DNA from the sample was amplified using SNV panel primers using VariantPlex® cycling optimized for a large panel of over 3500 primer pairs: i.PCR1 / 2 cycle number 10 / 15 ii. Holding time: 15 minutes iii. Annealing / extension temperature 60℃ / 65℃ iv. PCR primer amount increase test Amplified DNA libraries were sequenced and normalized to 12 million reads per library.
[0412] Quantification and comparison of copy number calls across all chromosomes determined by WGS and SNV panels for three exemplary samples are shown in Figures 2A, 2B, 3A, 3B, 4A, and 4B. Specifically, the ability of the SNV panel to accurately identify LOH was evaluated using WGS as a basis for comparison. The SNV panel and WGS showed good concordance of LOH calls in the three exemplary samples, especially in tumors with simple karyotypes and high cancer cell fractions in the samples (see Tables 3-5).
[0413] [Table 3]
[0414] [Table 4]
[0415] [Table 5]
[0416] Example 3. Design of SNV panel version 2 We designed SNV panel version 2 with increased SNV coverage, which has a 5-fold higher density of heterozygous SNVs compared to SNV panel version 1 (see Figures 5A and 5B), and therefore can provide more accurate LOH identification when assessed against WGS.
[0417] For SNV panel version 2, SNVs were selected according to the following selection criteria based on population and sequencing characteristics: The population characteristics were as follows: (1) 33%< allele frequency < 66%, and (2) 0< inbreeding coefficient<0.2.
[0418] The 5'-flanking sequence (50 base pairs) was characterized as follows: (1) GC percentage between 25% and 75%; (2) Unique; and (3) does not contain other common SNVs.
[0419] Additional primers for four thousand (4000) single nucleotide variants (SNVs) were added to obtain further coverage. To improve compatibility with low-quality FFPE input (multiple clinical origins), primer pairs close to each target are preferred. To include SNVs useful for detecting loss of heterozygosity (LOH) structural variants without copy number changes, select SNVs that are commonly heterozygous across subpopulations according to the current gnomAD release (v3). To select SNVs likely to generate the highest quality and quality NGS reads using AMP chemistry, avoid SNVs in amplicons adjacent to repetitive or GC-rich regions of the genome and prioritize SNVs that are less susceptible to noise during PCR or sequencing (e.g., not adjacent to polynucleotide tracts). Finally, to select SNVs that take into account the spatial granularity of genome calls, select SNVs that are as evenly distributed as possible across the genome.
[0420] Genomic DNA (>50ng) was extracted from FFPE samples (n=43) of multiple solid tumor types. Next generation sequencing was performed on anchored multiplex PCR libraries constructed using probes incorporating unique molecular identifiers and spanning 26 genes and 5,000 genome-wide common germline SNVs. Unmatched non-tumor samples (n=24) were used to generate a reference baseline dataset. Copy number imbalance at heterozygous SNVs was assessed and tumor purity was quantified using the FACETS algorithm, optimized to account for differences in DNA fragmentation between samples. Allele fractions of each heterozygous SNV were used to estimate allelic imbalance across chromosomal regions. The reference dataset was derived from matched FFPE tumor samples by whole genome sequencing (WGS) and sequence data analysis using three complementary algorithms. Allele-specific copy number analysis and tumor purity estimation from SNV Panel version 2 and WGS data were compared.
[0421] Copy number was assessable for 605 genes in 24 matched tumor samples that passed quality control filters. Median sequencing depth across samples by SNV Panel version 2 and WGS was 1346x and 18.6x, respectively. LOH detection by SNV Panel version 2 was reproducible (100%) across 170 genes in seven samples analyzed in duplicate. A strong correlation was observed between WGS and SNV Panel version 2 sample purity estimates (Pearson's r=0.81, p<0.001). Compared with WGS calls, the sensitivity and specificity of LOH detection by SNV Panel version 2 was 95% and 90%, respectively, increasing to 97% and 91% in regions with concordant LOH across all three WGS algorithms and 99% and 97% in diploid regions without subclonal mutations.
[0422] Figure 6 shows an example of a copy number profile compiled using SNV panel version 2 for a cancer cell with biallelic ATM loss of function. Quantification and comparison of copy number calls across all chromosomes determined by WGS and SNV panel version 2 for eight exemplary samples are shown in Figures 7A-14B. Specifically, the ability of SNV panel version 2 to accurately identify LOH was evaluated using WGS as a basis for comparison. The SNV panel and WGS showed good concordance of LOH calls in eight exemplary samples (see Tables 6-13).

[0431] Example 4. Biallelic ATM loss-of-function mutations in certain cancers The frequency of biallelic ATM deletions in tumors was estimated based on genomic data available in The Cancer Genome Atlas (Nature Genetics, 45:1113-1120, 2013). This dataset allowed for molecular characterization of tumor samples from over 10,000 patients classified into 33 cancer indications. Data indicating the presence of somatic mutations, copy number variation, or loss of heterozygosity were downloaded from the Genomic Data Commons Data Portal (portal.gdc.cancer.gov). Identification of pathogenic germline mutations in TCGA samples was obtained from published literature (Nature Commun. 8:857, 2017). Samples with the simultaneous presence of loss of heterozygosity and either germline or somatic pathogenic mutations were classified as biallelic deletions. Summarizing the mutation data by tumor indication showed that ATM biallelic deletions in the TCGA cohort were more frequent in cancers such as bladder urothelial carcinoma, pancreatic adenocarcinoma, and lung adenocarcinoma. The frequency of biallelic ATM mutations in various cancers is shown in Figures 7A and 7B: Figure 7A is a chart showing the frequency of biallelic ATM mutations in various cancers; Figure 7B is a chart showing the frequency of biallelic germline ATM mutations in various cancers.
