Study of Sacituzumab Govitecan-hziy and Pembrolizumab Versus Treatment of Physician's Choice and Pembrolizumab in Patients With Previously Untreated, Locally Advanced Inoperable or Metastatic Triple-Negative Breast Cancer

About

Brief 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).

  • Individuals may not be participating in a study with an investigational agent or investigational device within 4 weeks prior to randomization. Individuals participating in observational studies are eligible.
  • Have previously received topoisomerase 1 inhibitors or antibody drug conjugates containing a topoisomerase inhibitor.
