Summary

This study tests whether a combination of two drugs (imlunestrant and abemaciclib) given before surgery can shrink tumors in people with ER-positive, HER2-negative breast cancer. The treatment plan is adjusted based on a marker called Ki67 measured after two weeks. About 189 women aged 18-75 with early-stage breast cancer will take part. The goal is to see if this approach improves tumor response and long-term outcomes.
