Summary

This trial is testing whether the combination of atezolizumab and SRS is more effective in treating triple-negative breast cancer that has spread to the brain, than SRS alone.

Who is the study for?
This trial is for adults with triple-negative breast cancer that has spread to the brain. They must have stable brain metastases treatable with SRS, controlled steroid use, measurable disease outside the brain, and normal organ function. Pregnant women or those on high-dose steroids, previous anti-PD-1/PD-L1 therapy, or with certain medical conditions are excluded.
What is being tested?
The study tests combining atezolizumab (a drug) with stereotactic radiosurgery (SRS), a precise radiation procedure for treating brain tumors in patients whose breast cancer has spread to the brain.
What are the potential side effects?
Atezolizumab may cause immune-related reactions like inflammation of organs, infusion reactions similar to allergic responses, fatigue and potential lung issues. SRS can lead to headaches, swelling around the treatment area and temporary hair loss.
