Myriad Genetics Showcases Advancements in Precision Medicine with Recent Oncology Portfolio Expansion and New Data Presentations at ASCO 2022

SALT LAKE CITY, May 26, 2022 (GLOBE NEWSWIRE) -- Myriad Genetics, Inc., (NASDAQ: MYGN), a leader in genetic testing and precision medicine, will present multiple studies at the 2022 American Society of Clinical Oncology (ASCO) Annual Meeting, highlighting the value of genetic insights to guide and clarify cancer treatment and risk assessment.

The presentations underscore Myriad’s commitment to partnering with oncologists and other healthcare partners to support health equity and provide data-driven insights to help guide clinical care and improve outcomes. They follow the recent launch of Precise™ Oncology Solutions, a comprehensive suite of solutions offering germline testing, tumor profiling, and companion diagnostic options, including evaluation for homologous recombination deficiency (HRD). The suite offers a streamlined testing experience designed to help oncologists recommend personalized treatment plans for their patients.

Precise Oncology Solutions currently includes Myriad’s Precise™ Tumor Test, MyRisk™ Hereditary Cancer Test and its two FDA-approved companion diagnostic tests: MyChoice^® CDx and BRACAnalysis CDx^®. A new Precise Treatment Registry combines germline, somatic and HRD genetic data to accelerate the pace of precision cancer research and equitable advancements in patient care. Additionally, Myriad recently announced it will expand its strategic partnership with Intermountain Precision Genomics, a service of Intermountain Healthcare, to offer a liquid biopsy therapy selection test as part of its growing oncology portfolio in 2023.

Also at ASCO, Myriad will highlight a validation study for its market-leading MyRisk Hereditary Cancer Test with RiskScore^®, the first polygenic breast cancer risk assessment clinically and analytically validated for women of all ancestries. Providers can gain critical insights to help identify women with an increased risk of breast cancer who do not have a harmful mutation in well-known breast cancer genes, like BRCA1.

“Cancer prevention and treatment are most effective when informed by genetic insights,” said Thomas Slavin, M.D., chief medical officer, Myriad Genetics. “Our recent portfolio expansion and presentations at ASCO highlight our efforts to continually grow and innovate to better support physicians with comprehensive data-driven answers that inform treatment decisions, reduce healthcare disparities, and improve outcomes for all patients.”

Data from Myriad to be presented at the meeting:

A breast cancer (BC) risk model incorporating Tyrer-Cuzick version 8 (TCv8) and a polygenic risk score for diverse ancestries (Abstract #366104) 
Session Type: Poster Session
Date: Monday, June 6, 2022
Time: 8:00-11:00 a.m. CDT

This is the first breast cancer risk model to include breast density, family history and a polygenic risk score (PRS) based on genetically determined ancestry that is validated for diverse populations. The addition of PRS substantially improved risk stratification over TCv8 alone and may allow for a more personalized approach to breast cancer risk reduction.  

Ancestry-specific risk of triple-negative breast cancer (TNBC) associated with germline pathogenic variants (PV) in hereditary cancer (CA) predisposition genes (Abstract #377784)
Session Type: Poster Discussion
Date: Monday, June 6, 2022
Time: 4:30-6:00 p.m.; 1:15-4:15 p.m. CDT

In this population of women who had multigene panel testing, pathogenic variants in BRCA1, BRCA2, PALB2, RAD51C, RAD51D, and BARD1 were associated with substantial risk of triple-negative breast cancer (TNBC). There were no significant differences in pathogenic variant associated TNBC risks across ancestries. TNBC was reported more frequently in women of African ancestry.

Exploring homologous recombination deficiency thresholds for predicting response to platinum-based treatment in triple negative breast cancer (Abstract #364894)
Session Type: Poster Session
Date: Monday, June 6, 2022
Time: 8:00-11:00 a.m. CDT

This exploratory analysis evaluated the ability of ≥ 33 or ≥ 42 genomic instability score (GIS) thresholds to predict response to platinum-based treatment in patients with triple-negative breast cancer. This study of 204 tumors of mixed BRCA wild-type, BRCA mutations and unknown showed that a GIS of ≥ 33 may be the most appropriate threshold to predict response to platinum-based treatment in patients with TNBC; however, a prospective trial is needed.

Adherence to EndoPredict test scores for extended endocrine therapy management in the prospective EndoPredict Extended Endocrine Trial (EXET) (Abstract #371368)
Session Type: Poster Session
Date: Monday, June 6, 2022
Time: 8:00 -11:00 a.m. CDT

In this cohort of patients, even when accounting for other clinical factors such as node status, tumor grade, age at diagnosis, and other variables, Myriad’s EndoPredict® Breast Cancer Prognostic Test provided significant information for clinical decisions on extended endocrine therapy.
