Study Summary

This trial is testing the combination of pembrolizumab and fulvestrant to treat hormone receptor-positive, HER2-negative, advanced or metastatic breast cancer.

Who is the study for?
This trial is for adults with advanced breast cancer that's hormone receptor positive and HER-2 negative. Participants can have had no more than two prior treatments for metastatic disease, must not be pregnant or breastfeeding, agree to use contraception, and have good organ function and performance status. Exclusions include active infections, certain other cancers or treatments like anti-PD-1 drugs, live vaccines recently, or serious heart conditions.Check my eligibility
What is being tested?
The study tests Pembrolizumab combined with Fulvestrant in patients with specific breast cancer types. It aims to see if this combination helps control the disease better than current standard options. The trial requires a new tissue biopsy from participants for analysis.See study design
What are the potential side effects?
Pembrolizumab may cause immune-related side effects such as inflammation of organs (like lungs), skin reactions, liver issues; while Fulvestrant might lead to injection site pain, nausea, and bone marrow suppression which could increase infection risk.
