Myriad Genetics Announces Five Research Collaborations to Study the Use of MRD Testing in Breast Cancer

SALT LAKE CITY, Oct. 08, 2024 (GLOBE NEWSWIRE) -- , (NASDAQ: MYGN), a leader in genetic testing and precision medicine, today announced a series of ongoing research collaborations to study the use of molecular residual disease (MRD) testing in breast cancer using Myriad’s Precise^® MRD test.

Research collaborations include:

• A study to determine whether circulating tumor DNA (ctDNA) level may predict magnitude of response to pembrolizumab and hormonal therapy in patients with HR-positive inflammatory breast cancer who did not achieve pathological complete response at the time of surgery, led by Bora Lim, MD, at The University of Texas MD Anderson Cancer Center.
• A study to evaluate whether ctDNA levels correlate with nodal involvement in patients with newly diagnosed HR-positive breast cancer and, if so, how the correspondence may be used to aid in surgical decision making, led by Anna Weiss, MD, at The University of Rochester Medical Center.
• The multicenter, prospective MONITOR-breast study to determine the association of ctDNA levels to both neoadjuvant and adjuvant therapy in patients with newly diagnosed breast cancer across all subtypes. The study will involve 650 patients and will assess the prognostic potential of ctDNA and the lead time of detecting recurrence earlier ahead of standard-of-care imaging.
• The multicenter, prospective study to evaluate the maintenance of complete response with trastuzumab deruxtecan (T-DXd) in HER2-positive advanced or metastatic breast cancer patients and whether ctDNA can be used to optimally guide therapy, led by Yoichi Naito, MD, of the National Cancer Center Hospital East in Japan.
• A study in partnership with Aptitude Health to assess ctDNA levels in high-risk patients at diagnosis, during neoadjuvant treatment, and following surgery in community oncology settings.

“Relative to many other cancer types that typically have high levels of ctDNA in the blood, breast cancer often has very low levels of ctDNA, which makes MRD testing a challenge,” said Dale Muzzey, chief scientific officer, Myriad Genetics. “Myriad’s Precise MRD test is well suited to overcome this challenge because it tracks up to 1,000 tumor-specific variants identified via whole-genome sequencing. The research efforts we’re undertaking with leading organizations and investigators are an important step in advancing the clinical application of next-generation MRD testing to the treatment and monitoring of breast cancer.”

Myriad continues to develop its Precise MRD test to meet the needs of cancer patients, academic partners, and biopharma companies. Myriad has previously announced other MRD collaborations, including a metastatic breast cancer study with researchers at and a prospective pan-cancer study, including breast cancer, led by researchers at the

About Myriad’s Precise MRD Test

Myriad’s Precise MRD test is a tumor-informed, whole genome sequencing (WGS) based test that monitors hundreds to thousands of tumor-specific variants, which enables exceptional sensitivity and quantification of circulating tumor DNA (ctDNA) in the blood of patients with cancer. The Precise MRD test can be used to monitor ctDNA levels throughout a cancer patient’s clinical care, starting immediately after diagnosis and continuing through treatment and surveillance. The Precise MRD test is available for use in research studies pursued jointly by Myriad and academic or pharmaceutical investigators.
