Poster Presentations
Title:  Outcomes of clinical testing for tumor BRCA1 and BRCA2 gene analysis for 354 patients: First experience with tumor companion diagnostic for PARP inhibitors.
Presenter:  Karen Copeland, M.S.
Date:  Saturday, Oct. 8, 2016. 1:00-2:00 p.m.
Location:  Poster 874P (Abstract 4031).  Hall E.

This study assessed 354 patients with ovarian cancer undergoing BRCA1 and BRCA2 full sequencing and large rearrangement DNA analysis using the Tumor BRACAnalysis CDx® test.  The results show that, of the 354 samples analyzed, 93 (26.3 percent) tested positive for a pathogenic mutation; 57 were found in BRCA1 and 37 in BRCA2.  Of the pathogenic mutations detected, 93.6 percent were sequencing variants and 6.4 percent were large rearrangements.  These findings highlight the utility of the Tumor BRACAnalysis CDx test to accurately detect BRCA mutations in patients with ovarian cancer.

Title:  The molecular landscape of genome instability in prostate cancer.
Presenter:  Kirsten Timms, Ph.D.
Date:  Monday, Oct. 10, 2016. 1:00-2:00 p.m.
Location:  Poster 115P (Abstract 3247).  Hall E.

In this study, DNA from 95 prostate cancer (PC) tumors was analyzed to generate homologous recombination deficiency (HRD) and Microsatellite instability (MSI) and cell cycle progression (CCP) scores.  Additionally, 45 DNA damage repair (DDR) genes were sequenced and were considered non-functional if both alleles were mutated and/or deleted. If the second allele was intact, these genes were considered defective but functional.  The results showed that non-functional DDR genes (CDK12, PALB2, RPA1, ATM, and BRCA2) were observed in seven tumors and DDR gene defects in eight genes were observed in 11 tumors.  Importantly, the HRD score was significantly associated with DDR mutation status, Gleason score and CCP score. A significant proportion of aggressive prostate tumors carry molecular signatures associated with response to therapies targeting DDR deficiencies or to immune-therapeutics.  This study demonstrates the importance of assessing both alleles when identifying prostate tumors with DDR gene mutations.  In the study, an HRD score of ≥20 identified three times as many potential responders to HRD-dependent therapies compared to non-functional DDR gene mutations.

Title:  Characteristics of homologous recombination deficiency (HRD) in paired primary and recurrent high-grade serous ovarian cancer.
Presenter:  Jai Patel.
Date:  Monday, Oct. 10, 2016. 1:00-2:00 p.m.
Location:  Poster 113P (Abstract 3290).  Hall E.

In this study, the myChoice® HRD test was used to evaluate paired primary and recurrent tumors from 54 patients with high-grade serous ovarian cancer (HGSOC), the vast majority of whom were treated with adjuvant carboplatin and paclitaxel.  The objective was to determine if changes in the genomic profile of primary and recurrent tumors might impact the myChoice HRD score.  The results showed that there were no significant differences in the genomic markers evaluated between primary and recurrent tumors.  Importantly, the myChoice HRD test was not impacted by changes in the genomic profile. This finding suggests that testing recurrent HGSOC tumors would not alter treatment strategies relative to analysis of the primary tumor.

Title:  Homologous recombination deficiency (HRD) score shows superior association with outcome compared to its individual score components (LOH, TAI, and LST scores) in platinum treated serous ovarian cancer.
Presenter:  Jerry Lanchbury, Ph.D.
Date:  Monday, Oct. 10, 2016. 1:00-2:00 p.m.
Location:  Poster 112P (Abstract 2504).  Hall E.

The myChoice HRD score is the sum of three independent measures of HRD, including loss of heterozygosity (LOH), telomeric-allelic imbalance (TAI) and large-scale state transitions (LST).  This study compared the myChoice HRD score to its individual score components (LOH, TAI, and LST).   The results showed that the myChoice HRD score is a superior prognostic marker of HR deficiency than the individual scores.  There were a significant number of discrepancies between the myChoice HRD score and the individual component, which demonstrated a risk of both false positives and negatives.  These findings support the use of myChoice HRD, rather than the individual biomarkers, to inform treatment decisions for patients. 

About Tumor BRACAnalysis CDx®
Tumor BRACAnalysis CDx is a companion diagnostic test for identifying both germline and somatic cancer-causing mutations in the BRCA1 and BRCA2 genes.  Currently, Tumor BRACAnalysis CDx is a CE-marked genomic test designed to detect the presence of a BRCA1 or BRCA2 gene mutation in ovarian tumor tissue.  Additionally, Myriad is actively collaborating with leading pharmaceutical companies and academic centers to further develop Tumor BRACAnalysis CDx as a companion diagnostic for use with certain PARP inhibitors, platinum-based drugs and other chemotherapeutic agents.

About myChoice® HRD
Myriad's myChoice HRD is the most comprehensive homologous recombination deficiency test to detect when a tumor has lost the ability to repair double-stranded DNA breaks, resulting in increased susceptibility to DNA-damaging drugs such as platinum drugs or PARP inhibitors.  The myChoice HRD score is a composite of three proprietary technologies: loss of heterozygosity, telomeric allelic imbalance and large-scale state transitions.  Positive myChoice HRD scores, reflective of DNA repair deficiencies, are prevalent in all breast cancer subtypes, ovarian and most other major cancers. In previously published data, Myriad showed that the myChoice HRD test predicted drug response to platinum therapy in certain patients with triple-negative breast and ovarian cancers. It is estimated that 1.4 million people in the United States and Europe who are diagnosed with cancers annually may be candidates for treatment with DNA-damaging agents.
