Study Summary

The main purpose of this study is to evaluate the absorption, metabolism, and excretion (AME) profiles of pirtobrutinib (LOXO-305), to identify and characterize metabolites of pirtobrutinib (LOXO-305), and to assess the safety and tolerability of \[14C\] LOXO-305 in Part 1. To determine the absolute bioavailability of pirtobrutinib (LOXO-305), to evaluate the plasma concentration of total radioactivity, to evaluate the urinary excretion of \[14C\] LOXO-305 and total radioactivity, to evaluate the fecal excretion of \[14C\] LOXO-305 and total radioactivity, and to assess the safety and tolerability of pirtobrutinib (LOXO-305), and \[14C\] LOXO-305 in Part 2. Blood tests will be performed to check how much pirtobrutinib (LOXO-305) and \[14C\] LOXO-305 gets into the bloodstream and how long it takes the body to eliminate it. The study will last up to approximately 60 days for Part 1 and approximately 47 days for Part 2.

Primary Outcome

AUC0-inf of LOXO-305 in plasma.
