A Study of Carbon-14-Labelled [14C] LOXO-305 (Pirtobrutinib) in Healthy Male Participants

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.
