Recruiting studies in California
- 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+ - NCT06785636RecruitingPhase 1/Phase 2
New drug combination for advanced prostate cancer
This study tests a new drug (pocenbrodib) alone or combined with another hormone therapy (darolutamide) for men with advanced prostate cancer that has spread. It is for those who have already tried Pluvicto and one other hormone therapy, but not yet chemotherapy.
Fountain Valley, CaliforniaAges 18 years+ - NCT06943521RecruitingPhase 1/Phase 2
Study of MT-4561 for advanced solid tumors
This trial tests a new drug called MT-4561 in people with advanced solid tumors that have not responded to prior treatments. It aims to see if the drug can help shrink tumors or slow their growth.
Los Angeles, CaliforniaAges 18 years+ - NCT06990542RecruitingPhase 2
Focused radiation therapy for intermediate and high-risk prostate cancer
This trial tests a more precise radiation therapy that targets tumors seen on MRI or special scans, aiming to treat prostate cancer while reducing side effects. It is for men who have not had prostate surgery or previous radiation to the area.
La Jolla, CaliforniaAges 18 years+ - NCT06995053Recruiting
Prostate cancer radiation therapy with motion monitoring
This trial tests a precise radiation technique for prostate cancer that tracks the prostate during treatment. It aims to deliver higher radiation doses more safely, which may improve outcomes.
Los Angeles, CaliforniaAges 18 years+ - NCT07054346RecruitingPhase 1
Comparing two radiation drugs for high-risk prostate cancer before surgery
This trial tests two radioactive drugs (Lu-177 and Ac-225 PSMA-617) given before prostate removal surgery in men with high-risk prostate cancer that hasn't spread far. The goal is to see which drug works better at targeting cancer cells.
San Francisco, CaliforniaAges 18 years+ - NCT07145255RecruitingPhase 1/Phase 2
Study of MBRC-201 for advanced solid tumors
This trial tests a new drug, MBRC-201, for people with advanced solid tumors that have not responded to standard treatments. The goal is to find the best dose and see if it helps shrink tumors or slow their growth.
San Francisco, CaliforniaAges 18 years+ - NCT07219147RecruitingPhase 1
Combination treatment for advanced prostate cancer
This trial tests a combination of two treatments for advanced prostate cancer that has stopped responding to hormone therapy. One treatment is a targeted radiation therapy (177Lu-PSMA-617) and the other is an immunotherapy (sipuleucel-T) that helps your immune system fight the cancer.
Duarte, CaliforniaAges 18 years+ - NCT07276438Recruiting
Image-guided radiation therapy for localized prostate cancer
This trial tests a precise radiation technique that adapts to your body's daily changes. It may offer better outcomes for men with prostate cancer that hasn't spread outside the pelvic area.
Los Angeles, CaliforniaAges 18 years+ - NCT02016248Recruiting
Radiation “boost” for higher-risk prostate cancer
This trial studies whether adding a stronger “boost” dose of targeted radiation (SBRT) can better control higher-risk prostate cancer. It may help by increasing radiation coverage to the prostate while trying to limit treatment to surrounding areas.
Long Beach, CaliforniaAges 18 years+ - NCT00949819Recruiting
Active surveillance study for localized prostate cancer
This trial studies a “watchful waiting” approach, where doctors closely monitor certain prostate cancers with regular checkups and repeat biopsies. It may help people avoid or delay treatment side effects while watching for signs the cancer needs treatment.
Los Angeles, CaliforniaAges 30–85 - NCT02526368RecruitingEarly Phase 1
Scan your prostate with special MRI using pyruvate to find high-grade cancer
This trial tests whether a specialized MRI scan using a pyruvate tracer can better detect high-grade (more aggressive) prostate cancer. It may help doctors find cancer more accurately and guide treatment decisions or targeted follow-up.
San Francisco, CaliforniaAges 18 years+ - NCT07028853RecruitingPhase 3
New drug combo for advanced prostate cancer
This study tests whether adding the investigational drug mevrometostat to the standard treatment enzalutamide works better than enzalutamide alone for men with prostate cancer that has spread to other parts of the body (metastatic castration-sensitive prostate cancer). You may benefit if you haven't yet received chemotherapy or similar strong treatments for this stage of cancer.
Alhambra, CaliforniaAges 18 years+ - NCT07590934RecruitingPhase 1/Phase 2
Testing new cancer drugs for advanced prostate cancer
This study tests new anti-cancer drugs for men whose prostate cancer has spread and stopped responding to hormone therapy. The goal is to find treatments that work when standard drugs no longer help.
Duarte, CaliforniaAges 18–99 - NCT07468903Recruiting
Focal radiation for prostate cancer with HDR brachytherapy
This trial tests a targeted radiation treatment called HDR brachytherapy for prostate cancer that hasn't spread. It aims to treat only the cancer spots seen on MRI, which may reduce side effects.
Los Angeles, CaliforniaAges 40 years+ - NCT06217822RecruitingPhase 1
Testing a new radiation therapy for advanced prostate cancer
This trial tests a new radioactive drug, 225Ac-PSMA-Trillium, that targets prostate cancer cells. It is for people whose advanced prostate cancer has stopped responding to hormone therapy and may have spread.
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+ - NCT06267729RecruitingPhase 1/Phase 2
A new cell therapy for advanced prostate cancer
This trial tests a new cell therapy (AZD0754) for metastatic prostate cancer that has stopped responding to standard hormone therapy and chemotherapy. It’s looking for people whose cancer has gotten worse despite prior treatments, and who are still in fairly good health.
Duarte, CaliforniaAges 18–130 - NCT07181161RecruitingPhase 1/Phase 2
Testing a new drug for metastatic prostate cancer
This trial tests an investigational drug (AZD0516) alone or with other treatments in men with prostate cancer that has spread to other parts of the body and is no longer responding to hormone therapy. It aims to see if the drug can help control the cancer.
Los Angeles, CaliforniaAges 18–130 - 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+ - NCT06136650RecruitingPhase 3
Study of a new drug for advanced prostate cancer
This study tests a new oral drug called opevesostat against another standard hormone therapy for men with advanced prostate cancer that has spread and is no longer controlled by a first hormone therapy. It's for men who have not had chemotherapy for this stage and who have not used a PARP inhibitor or chose not to.
Irvine, CaliforniaAges 18 years+ - NCT06067841RecruitingPhase 1
New drug for advanced prostate cancer
This study tests a new drug (BMS-986460) for people with advanced prostate cancer that has stopped responding to hormone therapy. It aims to see if the drug can shrink or slow the cancer.
Palo Alto, CaliforniaAges 18 years+ - NCT06629779RecruitingPhase 3
Study of Mevrometostat for Advanced Prostate Cancer
This study tests a new drug called mevrometostat for men with a specific type of advanced prostate cancer that has spread and is still growing despite hormone therapy. It aims to see if the drug can help control the cancer.
Anaheim, CaliforniaAges 18 years+ - NCT05125016RecruitingPhase 1/Phase 2
Study drug for advanced prostate cancer after standard treatments
This early-phase study tests whether REGN4336 is safe and how well it works, by itself or with REGN5678, in adults with advanced prostate cancer. It may help people whose cancer has continued to worsen despite standard prostate cancer medicines.

What taking part in a prostate cancer (adenocarcinoma) 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.
