Summary

This Phase 3 trial tests whether the drug elacestrant can help prevent breast cancer from coming back in people with high-risk HR+/HER2- early breast cancer. About 1,520 participants will receive either elacestrant or standard hormone therapy for up to 7.5 years. The study compares how long people live without their cancer returning.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
Elacestrant (a hormone therapy drug)
What this could lead to
If successful, this could offer a more effective hormone therapy option for people with high-risk early breast cancer, potentially reducing the chance of cancer returning.
What could go wrong
This is a large Phase 3 trial, but results are not yet known. Elacestrant may not prove better than current treatments, and side effects are possible. The study is still recruiting.
