Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The main purpose of this study is to measure how much of Imlunestrant (LY3484356) gets into the bloodstream and how long it takes the body to eliminate it in female participants with impaired liver function compared to female participants with normal liver function. The side effects and tolerability of Imlunestrant will also be evaluated. The study may last up to 46 days for each participant.

Healthy Participants:

\- Healthy females as determined by medical history, physical examination, and other screening procedures, with normal liver function

Participants with Impaired Liver Function:

* Females with chronic mild, moderate and severe liver impairment, assessed by Child-Pugh scoring
* Have diagnosis of chronic hepatic impairment (\>6 months), with no clinically significant changes within 90 days prior to study drug administration.

Exclusion Criteria
