Overview
The goal of this clinical study is to find out how the study drug, sacituzumab govitecan (SG) works in participants with endometrial cancer who have received prior treatment with platinum-based chemotherapy and immunotherapy, versus the treatment of physician's choice (TPC).
The primary objectives of this study are to evaluate the effect of SG compared to TPC on progression-free survival (PFS) as assessed by blinded independent central review (BICR) and overall survival (OS).
