Study Summary

This trial tests a new drug to treat breast cancer in post-menopausal women.

Who is the study for?
This trial is for post-menopausal women over 18 with ER+/HER2- localized breast cancer that can be surgically removed. Participants must have a tumor at least 1.5 cm large, an ECOG performance status of 0 or 1, and agree to multiple biopsies and surgery. Women with severe liver disease, recent heart issues, certain infections like HIV/HBV/HCV, other active cancers within the last three years or prior breast cancer treatments are excluded.Check my eligibility
What is being tested?
The study compares two treatments before surgery in women with a specific type of breast cancer: ARV-471 (a new therapy) versus Anastrozole (an established treatment). The goal is to see which one works better at shrinking tumors when given before removing them surgically.See study design
What are the potential side effects?
Possible side effects include typical reactions related to hormone therapies such as hot flashes, joint pain, and fatigue. There may also be risks associated with surgical procedures including infection and bleeding.
