TROPHY-U-01 Cohort 2: A Phase II Study of Sacituzumab Govitecan in Cisplatin-Ineligible Patients With Metastatic Urothelial Cancer Progressing After Previous Checkpoint Inhibitor Therapy.

SG monotherapy demonstrated a relatively high ORR with rapid responses; this was feasible with a manageable toxicity profile in cisplatin-ineligible patients who had progression after CPI therapy. Limitations include a moderate sample size and lack of random assignment. These results warrant further evaluation of SG alone and in combinations in patients with LA/mUC.
