A Study of LY3502970 in Healthy Male Participants

April 29, 2026 updated by: Eli Lilly and Company

Disposition of [¹⁴C]-LY3502970 Following Oral Administration in Healthy Male Participants

The main purpose of this study is to measure how much of the study drug gets into the bloodstream and how long it takes the body to eliminate it. This study will involve a single dose of ¹⁴C radiolabelled LY3502970. This means that a radioactive substance will be incorporated into the study drug. The purposes are to investigate the study drug and its breakdown products and to find out how much of these pass from blood into urine and feces. The study will last up to 8 weeks (maximum).
