New drug duo takes on tough cancers: hope for advanced bladder, kidney, and melanoma patients
NCT ID NCT05661955
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study is testing a new combination of two immunotherapy drugs (BGB-A445 and tislelizumab) in about 113 people with advanced bladder, kidney, or skin cancer that has spread. The goal is to see if the combo can shrink tumors and how safe it is. Participants must have already tried at least one prior treatment.
