Recruiting studies in California
- 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+ - 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+ - NCT06809140RecruitingPhase 2
Bladder-sparing treatment for muscle-invasive bladder cancer
This trial tests a combination of two drugs, enfortumab vedotin and pembrolizumab, to treat bladder cancer that has grown into the muscle of the bladder. The goal is to shrink or eliminate the cancer so that surgery to remove the bladder may not be needed.
Duarte, 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+ - 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+ - NCT07061964RecruitingPhase 2
Immunotherapy and radiation to save the bladder
This trial tests whether combining immunotherapy and low-dose radiation after chemotherapy can help you avoid bladder removal. It's for people whose muscle-invasive bladder cancer has shrunk significantly after initial treatment.
Beverly Hills, 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+ - NCT06493552RecruitingPhase 2/Phase 3
Testing sEphB4-HSA in EphrinB2-high bladder cancer
This trial tests a new drug called sEphB4-HSA for people with a specific type of bladder cancer (urothelial carcinoma) that has high levels of a protein called EphrinB2. The study aims to see if this drug can shrink tumors or prevent them from growing, and it compares it to standard treatments like chemotherapy or immunotherapy.
Santa Monica, 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+ - NCT07097142RecruitingPhase 3
Shorter radiation for bladder cancer with chemo
This trial tests if a shorter course of radiation therapy works as well as the usual longer course for people with bladder cancer who are also receiving standard chemotherapy. The goal is to see if shorter treatment can reduce side effects while still being effective.
Orange, CaliforniaAges 18 years+ - NCT07129993RecruitingPhase 2/Phase 3
Comparing two drug combinations for advanced bladder cancer
This trial tests a new drug combination (Dato-DXd plus chemotherapy) against a standard chemotherapy combination for advanced bladder cancer that has spread or cannot be removed by surgery. It is for people whose cancer has grown after treatment with the drugs enfortumab vedotin (Padcev) and pembrolizumab (Keytruda).
Fullerton, CaliforniaAges 18 years+ - NCT07480356RecruitingPhase 3
Testing a new bladder cancer treatment (TARA-002) vs standard chemo
This trial compares a new medicine called TARA-002, given directly into the bladder, to the doctor's choice of standard chemotherapy. It is for people with a high-grade, non-muscle invasive bladder cancer that has not been treated with BCG or has not had BCG recently.
Bakersfield, CaliforniaAges 18 years+ - NCT07673016Recruiting
Collecting urine to test a new bladder cancer detection method
This study collects urine samples to test UroAmp, a new genetic test that may help detect and monitor bladder cancer. It is for people with bladder cancer or blood in urine who want to help improve cancer detection.
San Jose, CaliforniaAges 18 years+ - NCT07217171RecruitingPhase 1
Study of EVOLVE104 for advanced bladder and squamous cell cancers
This trial tests an experimental drug called EVOLVE104 for people with advanced bladder cancer or certain types of squamous cell cancers. It aims to see if the drug is safe and if it can help shrink tumors.
Duarte, CaliforniaAges 18 years+ - NCT07090499RecruitingPhase 1
Study of PF-08046876 for advanced solid tumors
This trial tests a new medicine, PF-08046876, for people with advanced cancers of the bladder, lung, head and neck, esophagus, or pancreas. It aims to see if the drug is safe and works against these cancers.
Duarte, CaliforniaAges 18 years+ - NCT03452774Recruiting

What taking part in a urothelial carcinoma bladder 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.
