Summary
The primary objective of this study is to compare the progression-free survival (PFS)
between sacituzumab govitecan-hziy (SG) and pembrolizumab versus treatment of physician's
choice (TPC) and pembrolizumab in participants with previously untreated, locally
advanced inoperable or metastatic triple-negative breast cancer, whose tumors express
programmed cell death ligand 1 (PD-L1).
