About this trial

The goal of this study is to find out if the experimental product, sacituzumab govitecan-hziy (SG) in combination with pembrolizumab given after surgery, is effective and safe compared to the treatment of physician's choice (TPC) which includes either pembrolizumab or pembrolizumab plus capecitabine in participants with triple negative breast cancer that still remains after surgery and pre-surgical treatment.
