Brief summary
The purpose of the study is to determine absorption, metabolism, and excretion of a single oral dose of \[14C\]-xevinapant. This information will enable assessment of absorption and clearance mechanisms of \[14C\]-xevinapant as well as identify metabolites. In addition, the study will allow to determine absolute bioavailability of xevinapant and understand its intravenous pharmacokinetics.
Interventions
\[14C\]-Xevinapant 200 mg administered as an oral solution on Day 1 of Part 1, containing approximately 100 microcurie (μCi) \[3.7 megabecquerel (MBq)\] in fasted conditions.
100 μg \[14C\]-xevinapant single dose administered as an IV bolus on Day 1, containing approximately 0.2 μCi \[7.4 kilobecquerel (kBq)\].
Xevinapant 200 mg administered as an oral solution on Day 1 of Part 2 in fasted conditions
