Recruiting studies in California
- 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+ - NCT06172478RecruitingPhase 2
HER3-DXd for advanced solid tumors after prior treatment
This trial tests a new targeted drug called HER3-DXd for people with several types of advanced solid tumors that have stopped responding to standard treatments. The drug is an antibody-drug conjugate, designed to deliver chemotherapy directly to cancer cells that have a protein called HER3 on their surface.
Duarte, 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+ - NCT04752722RecruitingPhase 1/Phase 2
Gene therapy for bladder cancer that came back after BCG
This study tests a new gene therapy (EG-70) given directly into the bladder for people with a high-risk bladder cancer called NMIBC. It may be an option if BCG treatment stopped working, or if you cannot have or choose not to have bladder removal surgery.
Irvine, CaliforniaAges 18 years+ - NCT06335667Recruiting
MRI vs. TURBT for muscle-invasive bladder cancer
This study compares two ways to check if bladder cancer has grown into the muscle layer: an MRI scan (mpMRI) versus a standard surgery called TURBT (where a small tool removes a sample of the tumor). The goal is to see if the MRI can be as accurate as the surgery, so future patients might avoid an extra procedure.
Orange, CaliforniaAges 18 years+ - NCT05334069Recruiting
Blood test study for early cancer detection in patients
This study collects blood from people with cancer and people without cancer (or with possible cancer) to test whether new blood tests can detect cancer earlier. Your blood samples help researchers evaluate how well these tests work.
Arroyo Grande, CaliforniaAges 40–75 - NCT07124000Recruiting
T-DXd for advanced HER2-positive solid tumors
This trial is for people with advanced HER2-positive solid tumors (cancers that cannot be removed by surgery or have spread). It tests the drug T-DXd (also called Enhertu) when your doctor has already decided it's the right treatment for you and you have no other good options.
San Diego, CaliforniaAges 18–130 - NCT07222488RecruitingPhase 1/Phase 2
Study of MK-3120 for bladder cancer
This trial tests a new drug, MK-3120, for people with a specific type of bladder cancer that hasn't spread into the muscle. It is for patients who either haven't had BCG treatment before or have had BCG treatment and their cancer came back more than 12 months but within 2 years after the last dose.
Bakersfield, CaliforniaAges 18 years+ - NCT03193541Recruiting
Testing a urine blood test to check for bladder cancer risk
This trial checks whether a new lab test on urine can help sort out which people with small amounts of blood in the urine (microscopic hematuria) might have bladder cancer. It may help doctors evaluate symptoms more accurately and decide who needs further testing.
Long Beach, CaliforniaAges 18–90 - NCT05366881Recruiting
Blood test study to spot early cancer signal and cancer leftovers
This observational study checks whether a blood test (a “cfDNA” test) can detect early signs of cancer or small amounts of cancer left after treatment. It may help doctors use a simple blood sample to improve cancer detection and follow-up.
Duarte, CaliforniaAges 40 years+ - NCT06173349RecruitingPhase 1
New bladder therapy for BCG-resistant bladder cancer
This trial tests a new treatment for bladder cancer that does not respond to standard BCG therapy. The treatment uses tiny particles (micelles) that deliver a chemotherapy drug directly into the bladder, aiming to destroy cancer cells without needing surgery.
Sacramento, CaliforniaAges 18 years+ - NCT06470282RecruitingPhase 1/Phase 2
Drug combo plus radiation for muscle-invasive bladder cancer
This trial tests a combination of two drugs (enfortumab vedotin and pembrolizumab) plus radiation therapy for people with bladder cancer that has grown into the muscle layer. The goal is to see if this treatment can kill the cancer while avoiding the need for bladder removal surgery.
San Francisco, 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.
Irvine, CaliforniaAges 18 years+ - NCT07000084RecruitingPhase 3
Testing gemcitabine with BCG for returning bladder cancer
This trial tests whether adding a chemotherapy drug called gemcitabine to the usual BCG therapy can help prevent bladder cancer from coming back again. If you have had BCG before and your cancer returned, this study might offer a more effective treatment option.
Irvine, CaliforniaAges 18 years+ - NCT07059884Recruiting
Exercise program to help people with cancer stay active
This trial tests a distance-based exercise program designed to help people on chemotherapy maintain their physical function and prevent disability. It is for patients with certain cancers who are working full-time and can participate in moderate physical activity.
Dublin, CaliforniaAges 18 years+ - NCT03193515Recruiting
Blood test to monitor bladder cancer returning
This trial tests a new blood test that looks for signs bladder cancer may be coming back in people with a recent history of bladder cancer. It may help by making surveillance easier, but you must still follow a scheduled bladder-check plan.
Los Angeles, 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+ - NCT06580002RecruitingPhase 2
Can Riluzole Help with Chemo Brain? A Pilot Study
This study tests if a medicine called riluzole (currently used for ALS) can help with 'chemo brain' – memory and thinking problems after cancer treatment. It is for people who feel their mental sharpness has declined after breast cancer therapy, certain chemotherapies, or brain radiation.
Orange, CaliforniaAges 18 years+ - NCT06465069RecruitingPhase 1
Study of a new drug for advanced bladder and other solid tumors
This study tests a new drug (LY4052031) for people with several types of advanced solid tumors, especially bladder cancer. It aims to see if the drug is safe and effective when given alone or after other treatments have stopped working.
Duarte, CaliforniaAges 18 years+ - NCT06242470RecruitingPhase 1
Study of MGC026 for advanced solid tumors
This trial tests a new drug called MGC026 that targets a protein called B7-H3 on cancer cells, aiming to shrink or slow different advanced solid tumors. It is an early-phase study to find the right dose and check safety.
Los Angeles, CaliforniaAges 18 years+ - NCT06337942Recruiting
Bladder or kidney-bladder transplant from a deceased donor
This trial offers a first-in-human transplant of a bladder or a kidney combined with a bladder from a deceased donor. It is for people with severe bladder problems or bladder cancer who already need a new bladder or are on immune-suppressing medicines for a prior organ transplant.
Los Angeles, CaliforniaAges 18–70 - NCT06101277Recruiting
Local therapy for limited new cancer growth in digestive cancers
This trial tests a cancer treatment that uses local therapies (like radiation or targeted heat) to destroy a small number of growing spots. It is for people with certain gastrointestinal cancers whose main treatment is working well except for a few new spots, so they can avoid switching to a different drug right away.
Sacramento, CaliforniaAges 18 years+ - NCT04585750RecruitingPhase 1/Phase 2
Study drug for TP53 Y220C-mutated advanced cancers
This early-phase study tests PC14586 (rezatapopt) in people with advanced or metastatic solid cancers that carry a specific TP53 mutation called Y220C. It mainly looks at safety and how well the treatment may work, sometimes combined with pembrolizumab.
Irvine, CaliforniaAges 12 years+ - NCT03452774Recruiting
AI matches your cancer tests to possible treatment trials
This trial uses an AI system to help match people with certain cancer types and specific tumor test results (like gene or protein markers) to relevant clinical trials. It may help you and your doctor find studies that fit your cancer biology faster.

What taking part in a bladder cancer 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.
