Summary
Brief summary
The main purpose of this study is to measure how well imlunestrant works compared to standard
hormone therapy, and how well imlunestrant with abemaciclib work compared to imlunestrant in
participants with breast cancer that is estrogen receptor positive (ER+) and human epidermal
receptor 2 negative (HER2-). Participants must have breast cancer that is advanced or has
spread to another part of the body. Study participation could last up to 5 years.
