A Randomized, Open-label, Phase 3 Study of Sacituzumab Govitecan and Pembrolizumab Versus Treatment of Physician’s Choice and Pembrolizumab in Patients With Previously Untreated, Locally Advanced, Inoperable, or Metastatic Triple-Negative Breast Cancer, Whose Tumors Express PD-L1.

The purpose of this study is to see if sacituzumab govitecan in combination with pembrolizumab can improve lifespans of patients with advanced, PD-L1 positive TNBC and their tumor does not grow or spread when compared to chemotherapy (paclitaxel, or nab-paclitaxel, or the combination of gemcitabine and carboplatin), a commonly used treatment for previously untreated advanced TNBC. In this clinical research study, we will be testing the experimental treatment which is a combination of Sacituzumab govitecan and Pembrolizumab.
