New hope for advanced bladder cancer: experimental drug combo enters late-stage trial
NCT ID NCT06225596
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests an experimental drug called BT8009, alone or with another drug (pembrolizumab), in people with advanced urothelial cancer that has spread. The goal is to see if it works better than standard chemotherapy. About 375 participants will be enrolled, some who have not had prior treatment and some who have. The study measures how long the cancer stays under control and any side effects.
