Presentations include analytical validation of Myriad's high-definition tumor informed MRD assay for breast cancer and its Breast Cancer Risk Assessment Tool MyRisk with RiskScore

SALT LAKE CITY, Dec. 09, 2024 (GLOBE NEWSWIRE) -- Myriad Genetics, Inc. (NASDAQ: MYGN), a leader in genetic testing and precision medicine, announced it will present new data at the 2024 San Antonio Breast Cancer Symposium (SABCS), including a spotlight presentation on a breast cancer risk assessment tool that combines a polygenic score for all ancestries.

Additional new data will show how Myriad's second-generation tumor-informed molecular residual disease (MRD) assay demonstrated high sensitivity, specificity and measurement accuracy, which, together, will facilitate improved resolution in residual-disease detection and extend lead times in recurrence detection.

"We are very excited to share validation data of our MRD assay. SABCS gives us the opportunity to showcase our clinical expertise in the prevention and treatment of early and advanced breast cancer," said George Daneker, MD, President and Chief Clinical Officer, Oncology, Myriad Genetics. "Myriad is one of the only labs that can offer germline and tumor genomic testing, combined with customizable workflow solutions and point-of-care patient education sessions. Our test results are supported by treatment-focused reporting, concordance checks between germline and tumor genomic results, and a summary sheet designed to help oncologists and breast surgeons interpret actionable insights more effectively."

In addition to data presentations, Myriad will welcome attendees to its booth (#1327) during exhibition hours. Among the Myriad products highlighted in the company's SABCS exhibit are:

• MyRisk Hereditary Cancer Test evaluates 48 genes to help healthcare providers identify their patients' risk of developing 11 different types of hereditary cancer. MyRisk's clear, actionable results are the foundation for personalized care plans to help patients make confident, informed decisions about medical management. MyRisk with RiskScore provides unaffected patients with a comprehensive, personalized assessment of the five-year risk and remaining lifetime risk of developing breast cancer.
• Precise Tumor Molecular Profile Test is a pan-cancer solid tumor comprehensive genomic profiling test that helps clinicians with straightforward interpretations, prioritization of therapies, and the next steps specific to each patient's genomic result.
• MyChoice CDx is one of the most comprehensive homologous recombination deficiency (HRD) tests available, enabling physicians to identify patients with tumors that have 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 test comprises tumor sequencing of the BRCA1 and BRCA2 genes and a composite of three proprietary technologies (loss of heterozygosity, telomeric allelic imbalance and large-scale state transitions).
• EndoPredict Breast Cancer Prognostic Test is for patients with ER+, HER2-, node negative or node positive breast cancer. The test provides three individualized results used to help determine the most appropriate breast cancer treatment.
