Summary

This study aimed to test whether adding the experimental drug boserolimab to standard treatment (pembrolizumab and chemotherapy) before surgery could help people with high-risk, early-stage triple-negative breast cancer. The goal was to see if the combination was safe and could eliminate all signs of cancer in the breast and lymph nodes removed during surgery. However, the study was withdrawn before enrolling any participants.
