Study Summary

This trial is testing a drug for breast cancer to determine its safety, dosage and effectiveness.

Who is the study for?
This trial is for adults with ER+/HER2- advanced or metastatic breast cancer who have tried at least one line of endocrine therapy. They must be able to swallow pills, have no major GI issues affecting drug absorption, and should not have symptomatic brain metastases requiring high-dose steroids.Check my eligibility
What is being tested?
The study tests AC699's safety, tolerable dosing levels, how the body processes it (pharmacokinetics), and its effectiveness in treating breast cancer. Participants will receive AC699 to determine these outcomes.See study design
What are the potential side effects?
While specific side effects of AC699 are not listed here, common ones may include reactions at the pill intake site, gastrointestinal disturbances due to oral administration, fatigue from treatment burden, and potential organ-specific inflammation.
