Summary

"This trial aims to see how well a combination of saruparib and camizestrant works compared to a standard treatment in patients with a specific type of advanced breast cancer."

Who is the study for?

This trial is for adults with advanced breast cancer that's HR-positive, HER2-negative, and has specific mutations (BRCA1, BRCA2, or PALB2). Participants should have good organ function and an ECOG performance status of 0 or 1. They must not have had certain treatments recently and should be able to swallow pills. People with severe nausea, GI diseases, bleeding disorders, active infections like HIV or hepatitis B/C, heart issues, or those on conflicting medications can't join.

What is being tested?

The study tests the effectiveness of Saruparib (AZD5305) combined with Camizestrant against standard CDK4/6 inhibitors plus endocrine therapy in treating advanced breast cancer. It aims to see if this new combination works better for patients who haven't responded well to other treatments.

What are the potential side effects?

Potential side effects may include nausea and vomiting from the medication itself; blood-related issues such as anemia; fatigue; possible liver enzyme changes indicating liver function impact; hormonal changes due to endocrine therapy; and potential interactions leading to heart rhythm problems.
