A Study of Effect of Multiple Doses of LOXO-305 on the Pharmacokinetics of Single Oral Doses of CYP1A2, CYP2C9, CYP2C19 Substrates in Healthy Participants

Registration Number
NCT06215430
Lead Sponsor
Eli Lilly and Company
Brief Summary

The main purpose of this study is to evaluate the effect of LOXO-305 on single oral dose of caffeine cytochrome P450 1A2 (CYP1A2) substrate, S-warfarin (CYP2C9 substrate), and omeprazole (CYP2C19 substrate) when administered as multiple doses by collecting the blood samples and conducting the blood tests to measure how much LOXO-305 is in the bloodstream and how the body handles and eliminates LOXO-305 in adult healthy participants. The study will also evaluate the safety and tolerability of LOXO-305. The study will be conducted in two periods. Participants will stay in this study for up to 67 days, including screening.
