Brief Summary
The purpose of the study is to investigate the routes of elimination and overall mass balance of 100 mg quemliclustat containing 75 μCi \[14C\] following a single IV infusion of \[14C\]-quemliclustat in healthy adult male participants, and to quantify total radioactivity (TRA) in plasma, whole blood, urine, and feces.
