EMERALD Trial Summary

This trial is testing a new drug, elacestrant, to see if it is more effective and has fewer side effects than the current best treatments for advanced breast cancer (fulvestrant or aromatase inhibitors).

Who is the study for?
This trial is for adults with ER+/HER2- advanced breast cancer who have progressed after endocrine therapy, including a CDK4/6 inhibitor. Participants can be postmenopausal women or men willing to prevent pregnancy. They should have measurable disease and may have had one chemotherapy line in the metastatic setting but no prior treatment with certain investigational drugs.Check my eligibility
What is being tested?
The study tests elacestrant against standard treatments (fulvestrant or an aromatase inhibitor) in patients whose cancer has worsened on endocrine therapy. It's a Phase 3 trial, meaning it's later in the testing process and involves more participants to confirm effectiveness and monitor side effects.See study design
What are the potential side effects?
While specific side effects of elacestrant are not listed here, common ones for this type of drug include hot flashes, joint pain, fatigue, nausea, and increased risk of bone thinning or fractures. Side effects vary by individual.
