Trial Summary

What is the purpose of this trial?

The main purpose of this study is to evaluate how much of the study drug (LY3866288), administered as a single dose that has the radioactive substance 14C incorporated into it, passes from blood into urine, feces and expired air in healthy participants. The study will also measure how much of the study drug gets into the bloodstream when taken orally, compared to when injected directly into the vein, how its broken down, and how long it takes the body to get rid of it. The study will also evaluate the safety and tolerability of LY3866288.The study is conducted in two parts. The study is expected to last approximately 68 days.
