A Study of Imlunestrant (LY3484356) in Female Healthy Participants

Registration Number
NCT05444556
Lead Sponsor
Eli Lilly and Company
Brief Summary

The main purpose of this study is to evaluate the effect of imlunestrant on repaglinide, omeprazole and dextromethorphan, and rosuvastatin and digoxin. The study will also investigate the effect of quinidine on imlunestrant in female healthy participants of non-childbearing potential. The safety and tolerability of imlunestrant will be investigated in female healthy participants of non-childbearing potential. The study will last approximately up to 32 days for each participant excluding the screening period.
