Study to Investigate the Absorption, Metabolism, and Excretion of [14C]-Pamiparib in Participants With Advanced Cancer

A Phase 1 Study to Investigate the Absorption, Metabolism, and Excretion of [14C]Pamiparib Following Single Oral Dose Administration in Patients With Advanced and/or Metastatic Solid Tumors

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.
