Capivasertib + Immunotherapy for Bladder Cancer

This study aims to determine whether adding an oral medication called Capivasertib to ongoing immunotherapy can enhance treatment responses in patients with advanced bladder cancer (aBC), as well as to evaluate the safety of this combination. Capivasertib is an anti-cancer drug approved by the U.S. Food and Drug Administration (FDA) for breast cancer, but it is not approved for aBC and, in this study, will be used as an investigational agent. Immunotherapy is FDA-approved for aBC, yet while some patients respond, others either do not benefit or develop resistance after an initial response. Previous research indicates that drugs similar to Capivasertib may increase the effectiveness of immunotherapy. Therefore, this study will enroll patients whose aBC no longer responds to immunotherapy, add Capivasertib to their treatment regimen, and monitor for improvements in immune response against aBC and any potential side effects associated with the combination therapy.
