This is an open-label study, in participants with advanced and/or metastatic solid tumors, which consists of 2 parts: a research phase (inpatient) and a treatment phase. The research phase (Part 1) of the study will assess the disposition of a single oral dose of \[14C\]-pamiparib. In the treatment phase (Part 2) participants will be allowed to have continued access to pamiparib.
