SALT LAKE CITY, Oct. 08, 2016 (GLOBE NEWSWIRE) -- Myriad Genetics, Inc. (MYGN), a leader in molecular diagnostics and personalized medicine, today announced that its myChoice^® HRD test identified more than double the number of patients who may benefit from treatment with niraparib than were identified by germline BRCA testing alone. The myChoice HRD test was evaluated in the NOVA study (NCT01847274) of nirarapib, an investigational oral PARP inhibitor being developed by TESARO (TSRO).

Today`s announcement follows publication of the NOVA study in the New England Journal of Medicine. NOVA is a well-controlled Phase 3 trial of niraparib that enrolled 553 patients with recurrent ovarian cancer who responded to their most recent platinum-based chemotherapy. This trial was designed to assess progression free survival (PFS) in a broad population of patients who were assigned to one of two cohorts based upon germline BRCA mutation status.

"Patients with ovarian cancer who tested positive with myChoice HRD experienced a clinically meaningful improvement in PFS," said Johnathan Lancaster, M.D., Ph.D., gynecologic oncologist and chief medical officer of Myriad Genetic Laboratories. "We estimate that myChoice HRD identifies more than double the number of patients who may benefit compared to germline BRCA testing alone."

The NOVA results showed that in patients who were germline BRCA mutation carriers, the median PFS for patients treated with niraparib was 21.0 months compared to 5.5 months for the control group (p

The myChoice HRD test is being developed in parallel with the clinical development of niraparib. The collaboration with TESARO began in March 2014 and includes several ongoing clinical trials in a variety of tumor types.

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.
