Talazoparib is an investigational poly-ADP ribose polymerase (PARP) inhibitor being developed by BioMarin. In the expanded relationship, the companies also will collaborate under FDA regulations and guidelines for the development and potential regulatory approval requirements for both talazoparib and myChoice HRD.

"Myriad is a pioneer in personalized medicine. Our companion diagnostics are providing clinicians with valuable biological data to accelerate and improve healthcare for their patients," said Mark Capone, president of Myriad Genetic Laboratories. "With cancer treatments, there is no one-size-fits-all approach for patients. We are excited to be working with BioMarin to help identify the patients who are most likely to benefit from talazoparib based on their own genetic makeup and biology."

The expansion adds to an ongoing collaboration that began in September 2013, when BioMarin began using Myriad’s BRACAnalysis CDx companion diagnostic test in its pivotal Phase 3 EMBRACA and Phase 2 ABRAZO clinical studies of talazoparib for advanced or metastatic breast cancer patients carrying BRCA mutations.
