San Francisco-based Medivation, Inc. , and San Rafael, Calif.-based BioMarin Pharmaceutical Inc. announced today that they have signed a deal for Medivation to buy all worldwide rights to talazoparib, formerly called BMN 673, for breast cancer treatment. Medivation will take over all research, development, regulatory and commercial activities.
Medivation will pay BioMarin $410 million upfront, and up to another $160 million in milestone payments. If marketed, BioMarin will receive mid-single digit royalties. The deal is expected to close by the end of this year.
Talazoparib in an oral poly ADP ribose polymerase (PARP) inhibitor. It is currently being studied in a Phase III trial for deleterious germline BRCA 1 and BRCA 2 mutations and locally advanced and/or metastatic breast cancer.
“Acquiring all worldwide rights to talazoparib provides Medivation with a transformational opportunity to diversify and expand our proprietary portfolio and global oncology franchise,” said David Hung, president and chief executive officer of Medivation in a statement. “PARP inhibitors are an exciting class of oncology therapeutics that have been associated with promising activity across multiple tumor types, including breast and prostate cancer.”
On June 17, BioMarin announced positive results for BMN-111 (vosoritide) to treat achondroplasia, the most common form of human dwarfism. That drug was in a Phase II trial and received Orphan designation in both the U.S. and Europe. Raluca Pancratov, an analyst with SunTrust Robinson Humphrey indicated in a research note that if approved, the drug could bring in sales of about $700 million globally.
BioMarin announced on Aug. 19 that the U.S. Food and Drug Administration (FDA) had granted its drug, drisapersen, rare pediatric disease designation for Duchenne Muscular Dystrophy (DMD).

Other companies working on PARP include AstraZeneca PLC ’s Lynparza and Clovis Oncology ’s rucaparib. Tesaro is working on niraparib for ovarian and breast cancer.
