Study of 2141-V11 for bladder cancer that did not respond to standard treatment
This trial tests a new drug, 2141-V11, for people with bladder cancer that has not gone away after standard treatments like BCG therapy. It may help those with non-muscle invasive bladder cancer or, in one group, muscle-invasive bladder cancer, who cannot have or choose not to have bladder removal surgery.
Basking Ridge, New JerseyAges 18 years+ - NCT05127824RecruitingPhase 2
Kidney cancer vaccine made from your own immune cells
This Phase 2 study tests a personalized kidney cancer vaccine made from your own immune cells. It aims to help your immune system recognize and attack clear cell kidney cancer after surgery, potentially lowering the chance of the cancer coming back.
Pittsburgh, PennsylvaniaAges 18 years+ - NCT05113537RecruitingPhase 1/Phase 2
Abemaciclib before PSMA cancer therapy for advanced prostate cancer
This trial tests whether taking abemaciclib before a PSMA-targeted radioligand can help people with advanced, treatment-resistant prostate cancer. The goal is to improve how well the PSMA therapy works while staying safe.
San Francisco, CaliforniaAges 18 years+ - NCT04763980Recruiting
Health coaching to help Black men get prostate germline genetic testing
This study tests a community health coach to help Black men with prostate cancer understand and access genetic testing that looks for inherited cancer risk. It may help you talk with your care team about testing and reduce barriers to getting results.
