Myriad Genetics Announces Second Foundational Patent Granted for Molecular Residual Disease (MRD) with Early Priority Date

SALT LAKE CITY, July 09, 2024 (GLOBE NEWSWIRE) -- Myriad Genetics, Inc., (NASDAQ: MYGN), a leader in genetic testing and precision medicine, today announced that the United States Patent and Trademark Office has issued a second patent that will strengthen its ability to deliver a tumor-informed, high-definition, molecular residual disease (MRD) assay to market. 

U.S. patent no. 12,024,749, entitled “Combinatorial DNA Screening,” covers Myriad’s groundbreaking platform MRD technology, which enables highly sensitive and specific tumor-informed, sequencing-based MRD assays such as Precise MRD. Specifically, the patented method relates to detecting circulating tumor DNA in patient fluid samples, including blood and plasma.

Earlier this year, Myriad Genetics announced its complementary patent granted for the company’s methods of preparing cell-free DNA that also enables high sensitivity tumor informed MRD assays. Together, these two patents support Myriad’s pioneering efforts to establish a proprietary and differentiated MRD assay that tracks thousands of tumor-specific variants identified via genome-scale sequencing technology, making it capable of detecting tumor DNA at lower levels than other products in the market today.

“The issuance of this second patent supporting our MRD assay development showcases another dimension of Myriad’s novel proprietary technology that we believe will help advance Myriad’s position as a precision medicine leader—both via its own Precise MRD offering and via potential licensing opportunities in the MRD space,” said Paul J. Diaz, president and CEO, Myriad Genetics. “We have developed our Precise® MRD assay by leveraging Myriad’s existing technology – laboratory systems, infrastructure, and intellectual property – and by building upon our FDA-approved MyChoice® CDx companion diagnostic and FirstGene platforms. We believe that our unique set of capabilities will enable us to profitably commercialize Precise MRD, advancing oncology care for patients in this emerging and under-penetrated market.”

Myriad continues to develop its Precise MRD assay to meet the needs of cancer patients, academic partners, and biopharma companies. The test is currently undergoing several high-impact studies while also transitioning to the company’s state-of-the-art laboratory facility in Salt Lake City. Myriad has announced several MRD collaborations, including a metastatic breast cancer study with researchers at Memorial Sloan Kettering, a metastatic renal cell carcinoma study with clinicians at The University of Texas MD Anderson Cancer Center, and a prospective pan-cancer study led by researchers at the National Cancer Center Hospital East in Japan. Preliminary results from multiple collaborations are expected to be released this fall.

Precise MRD is available for use in research studies pursued jointly by Myriad and academic or pharmaceutical investigators.
