Recruiting studies in California
- NCT06524544RecruitingPhase 3
Pembrolizumab and sacituzumab govitecan for advanced bladder cancer
This trial tests a new drug combination (pembrolizumab and sacituzumab govitecan) against standard treatment for advanced bladder cancer that has spread or cannot be removed by surgery. It's for people who have already tried an immunotherapy drug like pembrolizumab and another drug called enfortumab vedotin.
Irvine, CaliforniaAges 18 years+ - NCT05987241RecruitingPhase 2/Phase 3
Using a blood test to guide immunotherapy after bladder/kidney cancer surgery
This study tests whether a blood test that detects tumor DNA can help guide the use of immunotherapy (nivolumab with or without relatlimab) after surgery for urothelial cancer. The goal is to see if starting immunotherapy based on the blood test results can prevent the cancer from coming back.
Anaheim, CaliforniaAges 18 years+ - NCT03866382RecruitingPhase 2
Immunotherapy plus a targeted drug for rare genitourinary tumors
This Phase 2 study tests whether nivolumab and ipilimumab (immunotherapy drugs) plus cabozantinib (a targeted anti-cancer drug) can shrink or control rare cancers of the urinary/reproductive system that have spread. It may help by boosting the immune system and blocking cancer growth signals at the same time.
Arroyo Grande, CaliforniaAges 18 years+ - NCT05874921Recruiting
Registry for adults with UTUC treated with Jelmyto

Duarte, CaliforniaAges 18 years+ - NCT06774131RecruitingPhase 3
Study of UGN-104 for low-grade upper tract urothelial cancer
This trial tests a new treatment called UGN-104 for people with low-grade upper tract urothelial cancer (a type of cancer in the tube that carries urine from the kidney to the bladder). The treatment is given directly into the kidney area to kill cancer cells without surgery.
Orange, CaliforniaAges 18 years+ - NCT05562830RecruitingPhase 1/Phase 2
Study for bladder or urinary tract cancer after PD-1 failure
This Phase 1/2 study tests investigational cancer treatment(s) in people with locally advanced or metastatic urothelial cancer that has not responded to PD-1/PD-L1 immunotherapy. It may help by trying a new approach after prior checkpoint treatment has stopped working or the cancer returns.
San Francisco, CaliforniaAges 18 years+ - NCT06682728RecruitingPhase 2
Treating high-risk bladder cancer after surgery
This trial tests a combination of two drugs (sacituzumab govitecan and nivolumab) given after surgery to prevent the return of muscle-invasive bladder cancer. It is for patients whose cancer has a high chance of coming back despite surgery.
Orange, CaliforniaAges 18 years+ - NCT06770582RecruitingPhase 2
Adding immunotherapy to radiation for bladder cancer
This trial tests whether adding the immunotherapy drug pembrolizumab to radiation therapy works as well as or better than the usual chemotherapy given with radiation for a type of bladder cancer that has not invaded the muscle. It is for people whose cancer came back or has high-risk features and who would otherwise need to have their bladder removed.
Bakersfield, CaliforniaAges 18 years+ - NCT05521698RecruitingPhase 1
Bicalutamide study for early bladder cancer in men
This trial tests whether bicalutamide can help men with non-muscle invasive bladder cancer (an early form that hasn’t spread into muscle). It is a Phase 1 study, meaning the main goal is to see how safe it is and learn how it behaves in the body for this cancer type.
Los Angeles, CaliforniaAges 18 years+ - NCT06444815RecruitingPhase 1
Study of VET3-TGI for advanced solid tumors
This trial tests an experimental treatment called VET3-TGI, which is injected directly into tumors. It is for people with advanced solid tumors who have already tried other treatments and are looking for new options.
Orange, CaliforniaAges 18 years+ - NCT07421700RecruitingPhase 1/Phase 2
Study of PF-08634404 alone or with enfortumab vedotin for bladder cancer
This trial tests a new drug, PF-08634404, either by itself or together with another drug called enfortumab vedotin, for people with advanced bladder cancer that has spread. The goal is to see if these treatments can shrink tumors or slow the cancer's growth.
Alhambra, CaliforniaAges 18 years+ - NCT06047379RecruitingPhase 1/Phase 2
Testing NEO212 for brain tumors and metastases
This trial tests a new drug called NEO212 for people with certain brain tumors (like astrocytoma or glioblastoma) or cancer that has spread to the brain from other parts of the body. The goal is to see if it is safe and if it can help shrink or control the tumors.

What taking part in a urothelial carcinoma study involves
A screening visit first
Before anything else, the study team checks whether you fit — usually a visit with some tests. You can stop at any point, and screening is typically free.
Care at a nearby site
Study visits happen at a clinic or hospital taking part. Many studies cover the cost of the study treatment and related visits, and some reimburse travel.
You stay in control
Taking part is voluntary and you can leave a study at any time, for any reason, without affecting your regular care.
The team decides eligibility
Our fit check is a helpful first read, not a decision. The study team makes the final call after reviewing your health history.
