Talazoparib (1mg by mouth [PO] daily D1-28) will be provided as monotherapy for the first cycle. Starting with cycle 2 and for all subsequent cycles, treatment with avelumab (800 mg intravenously [IV] D1 every 2 weeks) will be added to talazoparib.
Talazoparib (formerly MDV3800 and BMN673) is an oral small molecule, selective inhibitor of PARP-1 and PARP-2.
