Immunomedics, Inc. announced positive results from cohort 1 of cisplatin-eligible patients in the pivotal Phase 2 TROPHY U-01 study of Trodelvy (sacituzumab govitecan-hziy) in metastatic urothelial cancer (mUC). Results confirm the interim findings and prior Phase 1/2 study results showing Trodelvy has significant activity and is safe in patients with heavily-pretreated mUC who progressed on both platinum-based chemotherapy and checkpoint inhibitors (CPI). Results for cohort 1 of TROPHY U-01 are summarized in the table below. As of data cutoff on May 18, 2020, eight of the 31 responders have an ongoing response and remain on treatment. Trodelvy has received Fast Track Designation from the U.S. Food and Drug Administration (FDA) in this indication. Trodelvy continued to demonstrate a tolerable and predictable safety profile consistent with previous observations in mUC and other tumor types. Treatment-related Grade 3 and 4 adverse events were mostly hematologic and gastrointestinal related, including neutropenia (34%) and diarrhea (10%). Seven patients (6%) discontinued treatment due to adverse events, three of whom due to neutropenia or its complications. There was one treatment-related death from sepsis due to febrile neutropenia. There were no grade 2 or above events of neuropathy or rash, and no cases of interstitial lung disease reported.
