Phase 3 Study of Vepugratinib with Enfortumab Vedotin and Pembrolizumab in Adults with Advanced or Metastatic Bladder Cancer Having FGFR3 Genetic Changes

What this Trial Is About

Researchers are evaluating vepugratinib, a new medicine, to see if it is safe and helpful for people with advanced or metastatic urothelial carcinoma, a type of bladder cancer with FGFR3 genetic changes. This Phase 3 study compares vepugratinib combined with enfortumab vedotin and pembrolizumab against a placebo combined with these same drugs. The trial is sponsored by Eli Lilly and Company and aims to assess treatment safety and effectiveness over a long period. Participants receive either vepugratinib or a placebo orally, together with enfortumab vedotin and pembrolizumab given by intravenous infusion. The study uses a double-blind, randomized design with parallel groups to compare these treatments. There is a safety lead-in phase followed by the main treatment phase, and study participation may last up to approximately 6 years. During the trial, participants will have regular assessments including monitoring for treatment-related side effects, tumor response, progression-free survival, overall survival, and quality of life using questionnaires. Researchers will collect blood samples to measure drug levels and evaluate health status at baseline and throughout the study. Safety and effectiveness outcomes will be tracked up to 90 months, with continuous monitoring to ensure participant well-being over the long-term study period.
