Tumor mutational burden Tumor mutational burden (TMB) is a measure of the mutation load in a tumor sample. TMB for this tumor sample is determined to fall in the Low TMB category. High TMB is associated with production of more neo-antigens which may be recognized by the immune system and inciting an anti-tumor response. High TMB is associated with better response rate with immune-checkpoint inhibitor

Microsatellite Instability

Microsatellite Instability (MSI) refers to a type of genomic instability in tumor tissue caused by the failure of the DNA mismatch repair system to repair errors during DNA replication. This process results in accumulation of various mutations including alterations in the length of small repetitive microsatellite sequences. MSI for this tumor sample is found to fall in the MSI-Stable category.

CLINICAL TRIAL We found a clinical trial investigating the effect of high-dose alkylating chemotherapy compared with

standard chemotherapy as part of a multimodality treatment approach in patients with oligo-metastatic breast cancer harboring homologous recombination deficiency.

These high- alkylating chemotherapy regimens contain potent inducers of DNA double-strand breaks (DSB), which are highly effective in tumors with an inadequate DNA repair system. The tumor suppressor genes BRCA1 and BRCA2 are involved in the repair of DNA DSB via homologous recombination. When this mechanism is inactivated, tumor cells rely on less adequate repair mechanisms. This is called homologous recombination deficiency (HRD) and causes genome instability and consequently apoptosis of tumor cells. Hence, targeting BRCA2 mutation with an altered chemotherapy regime is recommended to treat breast cancer.

Drug details –

Carboplatin, Thiotepa, and Cyclophosphamide

This study investigates the effect of high-dose alkylating chemotherapy compared with standard chemotherapy as part of a multimodality treatment approach in patients with oligo-metastatic breast cancer harboring homologous recombination deficiency.

Studies have shown that patients with high-risk breast cancer and a BRCA1- or BRCA2-like profile derive important benefit from high-dose, alkylating chemotherapy in comparison to conventional chemotherapy (hazard ratio (HR) for overall survival: 0.19, 95% confidence interval (CI): 0.08 to 0.48). It is suggested that selecting oligo-metastatic patients based on HRD for high-dose chemotherapy can improve outcome for more patients.

Drug Details –

Olaparib

Olaparib is a small molecule inhibitor of the nuclear enzyme poly (ADP-ribose) polymerase (PARP) with potential

chemosensitizing, radiosensitizing, and antineoplastic activities. It selectively binds to and inhibits PARP, inhibiting

PARP-mediated repair of single strand DNA breaks; PARP inhibition may enhance the cytotoxicity of DNA-

damaging agents and may reverse tumor cell chemoresistance and radioresistance. PARP catalyzes post-

translational ADP-ribosylation of nuclear proteins and can be activated by single-stranded DNA breaks.

Olaparib and Adavosertib

Olaparib (AZD-2281, MK-7339 trade name Lynparza) is an FDA-approved targeted therapy for cancer. It is a PARP inhibitor, inhibiting poly ADP ribose polymerase (PARP), an enzyme involved in DNA repair. Adavosertib (AZD1775) is a first-in-class, potent, and selective inhibitor of WEE1 with proof of chemo- potentiation in p53-deficient tumors in preclinical models. (Chen, Dongshao, 2018)

Given that PARP inhibition by olaparib results in DNA double-strand breaks in S phase, it is hypothesized that combined Wee1 kinase and PARP inhibition could induce tumor cell death. Remarkable synergy was observed using an AZD1775/olaparib combination in small-cell lung cancer (SCLC) xenograft models (O’Connor, EORTC 2015).

Cetuximab

This study aims at evaluating the effect of cetuximab monotherapy as maintenance treatment, versus continuation after 8 courses of

induction therapy with cetuximab plus standard chemotherapy regimen (FOLFIRI or mFOLFOX6)in metastatic colorectal cancer (mCRC) patients.

The maintenance treatments are continued until disease progression or untolerated toxicity. The aim of this study is to demonstrate that cetuximab monotherapy is non-inferior to continuation treatment, in those mCRC patients who responded to induction therapy (SD, PR, or CR), and carry biomarker-panels (KRAS, NRAS, BRAF, and PIK3CA) favor EGFR antibody. (Details of clinical trial on page 4) (NCT02942706)

Pembrolizumab

Pembrolizumab is a highly selective IgG4-kappa humanized monoclonal antibody against PD-1 receptor. Pembrolizumab targets and blocks a protein called PD-1 on the surface of certain immune cells called T-cells. Blocking PD-1 triggers the T-cells to find and kill cancer cells. Pembrolizumab is very well tolerated so many patients who have difficulty tolerating chemotherapy may be able to handle this medication,

In the phase Ib KEYNOTE-012 study which evaluated pembrolizumab monotherapy at 10 mg/kg ever 2 weeks in patients with gastric cancer were recently reported. Most patients had two or more prior lines of therapy. In the study, 41% of evaluable patients showed tumor shrinkage. The overall response rate in 39 patients were 31%.

Adavosertib, Paclitaxel

This study is a single arm, single center phase II study of AZD1775 in combination with paclitaxel in patients with

advanced gastric adenocarcinoma harboring TP53 mutation as a second-line chemotherapy.

AZD1775 is an inhibitor of Wee1, a protein tyrosine kinase. Wee1 phosphorylates and inhibits cyclin- dependent

kinases 1 (CDK1) and 2 (CDK2), and is involved in regulation of the intra-S and G2 cell cycle checkpoints.

In in-vitro and in-vivo preclinical models, AZD1775 selectively enhanced chemotherapy induced death of cells deficient in p53 signaling. Tumor context-specific sensitization to the DNA damaging agents, gemcitabine and platinum, was observed in TOV21G (ovarian carcinoma) cell lines matched for wild type and knock down of p53

GENES OVERVIEW

Variant details

TP53 – Tumor suppressor protein 53

TP53 is a well-known tumor suppressor gene and has various mechanisms of anticancer function and plays

significant role in maintenance of genome integrity, apoptosis, genomic stability, and inhibition of angiogenesis

etc. Loss of TP53 function allows deregulated survival of genetically impaired abnormal cells which can lead to

neoplastic conversion of later on. It is altered in 39.49% of all cancers with mutations in 32.77% of breast carcinoma patients.

APC- Adenomatous polyposis coli

APC is a gene that encodes a tumor suppressor protein that acts as an antagonist of the Wnt signaling pathway.

It is also involved in other processes including cell migration and adhesion, transcriptional activation, and

apoptosis .Defects in this gene cause familial adenomatous polyposis (FAP), an autosomal dominant pre-

malignant disease that usually progresses to malignancy. APC also play a rate-limiting role in the majority of

sporadic colorectal cancers.

APC is altered in 10.55% of all cancers with mutations in 2.04% of breast carcinoma patients.

BRCA2 – Breast cancer 2

BRCA2 is a gene that encodes a protein that functions in maintaining genomic stability and as a tumor suppressor.

BRCA2 is a mediator of the core mechanism of homologous recombination. BRCA2 loss- of-function truncation

mutant display some defects in replication and checkpoint control.

BRCA2 alterations allow cells to bypass checkpoint controls and evade apoptosis, and thereby initiate

tumorigenesis. BRCA2 is altered in 4.63% of all cancers with mutations in 3.95% of breast carcinoma patients.

POLE – Polymerase (DNA directed), epsilon, catalytic subunit

POLE is a gene that encodes a protein that is a catalytic component of DNA polymerase epsilon. The enzymatic

protein functions in DNA repair and chromosomal DNA replication. Polε is also involved in DNA repair pathways

such as mismatch repair (MMR), base excision repair (BER), nucleotide excision repair (NER) or double-strand

break repair. (Guerro J et al, 2017)

Pathogenic somatic mutations in the proofreading domain of POLE have been found in some tumour types at

moderate or rare frequencies. Some mutations in the polymerase domain have been suggested to be drivers.

POLE is altered in 3.43% of all cancers with mutations in 1.78% of breast carcinoma patients

PMS2 – Post-meiotic segregation increased 2

PMS2 is a gene that encodes a protein that functions in DNA mismatch repair that functions to correct DNA

mismatches and small insertions and deletions that can occur during DNA replication and homologous

recombination. Also implicated in DNA damage signalling, a process which induces cell cycle arrest and can lead

to apoptosis in case of major DNA damages.

PMS2 is altered in 1.38% of all cancers with mutations in 0.81% of breast carcinoma patients.

BAP1 – BRCA1 associated protein 1

BAP1 is a tumor suppressor gene important to the development and prognosis of many cancers, especially uveal

melanoma (UM). BAP1 is a scavenger protein that regulates cell cycle, cellular differentiation, and DNA damage

response. BAP1 was first shown to act as a tumor suppressor in cultured cells, where its deubiquitinase (UCH)

domain and nuclear localization sequences were required for BAP1 to suppress cell growth. BAP1 is altered in

2.04% of all cancers.

NTRK1 – Neurotrophic receptor tyrosine kinase 1

The NTRK1 gene provides instructions for making a protein that is essential for the development and survival of

nerve cells (neurons), especially those that transmit information about sensations such as pain, temperature,

and touch (sensory neurons). The NTRK1 protein is found on the surface of cells, particularly sensory neurons.

Trk (neurotrophin) receptors are single transmembrane catalytic receptors with intracellular tyrosine kinase

activity.

NTRK1 is altered in 2.21% of all cancers with mutations in 1.71% of breast carcinoma patients.

STK11- Serine/threonine kinase 11

STK11 is a gene that encodes a protein that belongs to the serine/threonine kinase family. The protein functions

in the regulation of cell polarity and is also a tumor suppressor. STK11 has been reported to play a critical role in

P53-mediated cell apoptosis. STK11 gene is involved in cell cycle regulation and apoptosis, whose abnormality

can induce and promote tumorigenesis.

STK11 is altered in 2.56% of all cancers with mutations in 1.23% of breast carcinoma patients.

NF1 – Neurofibromin 1

NF1 is a gene that codes for neurofibromin, a tumor suppressor protein. NF1 suppresses the function of the Ras

protein, which promotes cell growth and differentiation. In cancer, the tumor suppression function of the gene

is impaired, leading to conditions favorable for uncontrolled cell growth. NF1 mutations have been observed in

multiple cancer types, including myelodysplastic syndromes.

NF1 is altered in 6.78% of all cancers with mutations in 4.83% of breast carcinoma patients.

TEST DESCRIPTION

Somatic Genomic Test- Target Focus is a Next Generation Sequencing based test which identifies genetic alterations in a comprehensive panel of well curated 352 tumor genes which can impact response to approved therapy for a particular cancer type. Some of the alterations detected may have bearing on prognosis and/or therapeutic options and may provide relevant information that allows doctor to consider various lines of targeted treatment for the patient.

Sample preparation and Library preparation:

DNA isolated from FFPE or any other fresh tumor tissue source was used to perform targeted gene capture using a custom capture kit. The libraries were sequenced to mean >100X coverage on Illumina sequencing platform.

Bioinformatics Analysis and Reporting:

The sequences obtained are aligned to human reference genome (GRCh37/hg19) and variant analysis was performed using set of Bioinformatics Pipeline. Clinically relevant mutations were annotated using published variants in literature and a set of databases – ClinVar, COSMIC Drugs and Clinical Trials, FDA Approval Drugs. Common variants are filtered based on allele frequency in 1000 Genome Phase 3, ExAC, EVS, dbSNP147, etc. Non-synonymous variants effect is calculated using multiple algorithms such as PolyPhen-2, SIFT, MutationTaster2, Mutation Assessor and LRT. Only non-synonymous and splice site variants found in the clinical exome panel consisting of specific set of genes were used for clinical interpretation. Silent variations that do not result in any change in amino acid in the coding region are not reported.

Tumor Mutation Burden (TMB) is an evolving and promising biomarker for predicting a response to immunotherapy treatment. TMB is calculated by estimating the somatic non synonymous coding mutation as identified by Whole Exome Sequencing. A sample is categorized as High TMB if the TMB is found to be ≥20 mutations / megabase.

LIMITATIONS AND DISCLAIMER

DNA studies do not constitute a definitive test for the selected condition(s) in all individuals. It should be

realized that there are possible sources of error. Errors can result from trace contamination, rare technical errors,

rare genetic variants that interfere with analysis, recent scientific developments, and alternative classification

systems. This test should be one of the many aspects used by the healthcare provider to help with a diagnosis and

treatment plan.

The contents of this test should be carefully assessed by the treating physician and further interpreted

along with clinical, histopathological findings, contraindications and guidelines before deciding the course of

therapy.

Most recent block is recommended for testing as the mutation profile may change in response to treatment

and hence differ at different sampling points.

Somatic Genomic Test has not been cleared or approved by the FDA.

Large deletions of more than 10 bp or copy number variations /chromosomal rearrangements cannot be

assessed using this method.

Certain genes may not be covered completely, and few mutations could be missed. A negative result

cannot rule out the possibility that the tested tumor sample carries mutations not previously associated with

cancer and hence not included in the panel.

The following table represents the panel of 352 genes, evaluated in the Target Focus test, commonly known to be

associated with different cancers and cancer syndromes.
