Recruiting studies in California
- NCT06545955RecruitingPhase 3
Gene therapy study for high-grade bladder cancer not responding to BCG
This trial tests a gene therapy called nadofaragene firadenovec, given directly into the bladder, either alone or with chemo or immunotherapy. It's for people with high-grade bladder cancer that hasn't gone away after BCG treatment.
Los Angeles, CaliforniaAges 18 years+ - NCT05710848RecruitingPhase 1/Phase 2
Study drug for repeat bladder tumor surgery patients
This trial tests STM-416, given around the time you have surgery to remove recurring bladder tumors, to see if it can reduce the chance the cancer comes back. It is for people with high-risk early bladder cancer (non–muscle-invasive) who have already had standard treatment and now need another TURBT.
Bakersfield, CaliforniaAges 18 years+ - NCT05951179RecruitingPhase 2
Bladder instillation study for high-grade non–muscle-invasive cancer
This Phase 2 trial tests TARA-002 given directly into the bladder to treat high-grade non–muscle-invasive bladder cancer with active disease. It may help patients who have not previously responded to, or have not received, BCG treatment in the recent past.
Bakersfield, CaliforniaAges 18 years+ - NCT07566156RecruitingPhase 3
New drug combination vs. radiation for bladder cancer preservation
This trial tests whether two drugs (enfortumab vedotin and pembrolizumab) work better than radiation with chemotherapy for muscle-invasive bladder cancer. The goal is to treat your cancer while keeping your bladder instead of removing it.
Santa Barbara, 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+ - NCT04442724Recruiting
MRI and bladder marker planning to guide bladder chemoradiation
This trial uses special MRI scans and tiny markers placed in the bladder to better plan bladder chemoradiation. The goal is to help target treatment more accurately and improve how well it can be delivered.
Los Angeles, CaliforniaAges 18 years+ - NCT06510374RecruitingPhase 3
Gene therapy vs. observation for intermediate risk bladder cancer
This trial tests a new gene therapy called nadofaragene firadenovec versus just watching and waiting (observation) for people with a specific type of bladder cancer that hasn't grown into the muscle. The goal is to see if the gene therapy can help keep the cancer from coming back.
Bakersfield, CaliforniaAges 18 years+ - NCT07218003Enrolling by invitationPhase 1
Study of RNDO-564 alone or with pembrolizumab for bladder cancer
This trial tests an experimental drug, RNDO-564, either by itself or combined with another drug (pembrolizumab), for people with advanced bladder cancer or other solid tumors that have stopped responding to standard treatments. The goal is to see if it can shrink tumors or slow cancer growth.
San Francisco, CaliforniaAges 18 years+ - NCT06637423RecruitingPhase 1/Phase 2
Study of sacituzumab tirumotecan for low-grade bladder cancer
This trial tests a new drug called sacituzumab tirumotecan for people with low-grade bladder cancer that hasn't spread into the bladder muscle. The goal is to see if it can help shrink or control the tumors.
Bakersfield, CaliforniaAges 18 years+ - NCT06778863RecruitingPhase 1
A study of CLSP-1025 for adults with certain solid tumors
This trial tests a new drug called CLSP-1025 for people with advanced solid tumors that have a specific change in the p53 gene (R175H). The drug targets this change to help fight the cancer.
Los Angeles, CaliforniaAges 18 years+ - NCT06253871RecruitingPhase 1
Study of IAM1363 for HER2 Cancers
This trial tests a new oral drug called IAM1363 for people with HER2-altered cancers that have stopped responding to previous treatments. The goal is to see if the drug is safe and how well it works against these cancers.
La Jolla, CaliforniaAges 18 years+ - NCT05086692RecruitingPhase 1/Phase 2
Beta-only IL-2 therapy for advanced solid tumors
This Phase 1/2 study tests a beta-only version of IL-2, an immune-stimulating treatment, to shrink or control advanced or metastatic solid tumors. It’s mainly designed to check safety and to see if it can help patients by improving tumor response.
San Diego, CaliforniaAges 18 years+ - NCT06319820RecruitingPhase 3
TAR-210 vs standard bladder chemo for FGFR-mutated bladder cancer
This trial compares a new drug, TAR-210, which is placed directly into the bladder, against standard chemotherapy given through a catheter. It is for people with a specific type of bladder cancer that has a change in the FGFR gene.
Los Alamitos, CaliforniaAges 18 years+ - NCT07129993RecruitingPhase 2/Phase 3
Study of datopotamab deruxtecan with chemo for advanced bladder cancer
This trial is testing a new drug combination for advanced bladder cancer that has grown despite previous treatment. It pairs a targeted therapy (datopotamab deruxtecan) with chemotherapy, and the goal is to see if it can slow down or stop the cancer better than standard chemo alone.
Fullerton, CaliforniaAges 18 years+ - NCT06528990RecruitingPhase 2
Telehealth help for ostomy self-care
This study tests a telehealth program to help you manage your ostomy after surgery. If you have bladder or colorectal cancer and are getting an ostomy, you and a caregiver can learn skills to handle your new stoma from home using video calls.
Duarte, CaliforniaAges 18 years+ - NCT07514143Recruiting
Bladder Cancer Detection Study Using Urine Test
This study tests a new urine-based test called EpiCheck to help detect bladder cancer. You'll provide urine samples before or during a bladder procedure you're already scheduled to have, and researchers will see how well the test works.
San Diego, CaliforniaAges 22 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+ - 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+ - NCT06833073RecruitingPhase 2
Study of an mRNA vaccine and BCG for bladder cancer
This trial tests an experimental mRNA vaccine (V940) combined with BCG therapy for people with high-risk non-muscle invasive bladder cancer that hasn't spread. It aims to see if the vaccine can help the immune system better fight the cancer.
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+ - NCT06919965RecruitingPhase 3
TAR-210 vs. standard bladder chemo for high-risk bladder cancer
This trial compares a new drug called TAR-210, given directly into the bladder, to standard chemotherapy for people with a specific type of high-risk bladder cancer that has not invaded muscle. It tests if TAR-210 can be more effective with fewer side effects.
Los Angeles, CaliforniaAges 18 years+ - NCT07232602RecruitingPhase 1/Phase 2

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.
