Summary

This trial studies a new medication (ARV-471) with an existing one (palbociclib) to compare to standard of care therapy for advanced breast cancer.

Who is the study for?
This trial is for adults with advanced breast cancer that can't be cured by surgery or radiation, who haven't had systemic treatment for their recurrent or metastatic disease. They should have estrogen receptor positive and HER2 negative tumors, good performance status (ECOG 0-2), and be able to provide tissue samples.
What is being tested?
The study tests ARV-471 combined with palbociclib against the standard letrozole plus palbociclib in treating advanced breast cancer. Initially, two doses of palbociclib are tested to find the best one for Phase 3, where participants will randomly receive either combination orally once daily until progression or unacceptable side effects.
What are the potential side effects?
Potential side effects include reactions related to hormone therapy such as hot flashes and joint pain, along with those common to cancer treatments like nausea, fatigue, blood cell count changes which could increase infection risk, liver function alterations and possible heart issues.
