Los Angeles, 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+ - NCT07200830RecruitingPhase 3
Testing different schedules of a targeted radiation drug for advanced prostate cancer
This trial tests two different dosing schedules of a drug called Lutetium-177 PSMA RLT, which delivers radiation directly to prostate cancer cells. It is for men with advanced prostate cancer that has stopped responding to hormone therapy and has spread, who have not yet had chemotherapy for this stage of the disease.
Bakersfield, 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+ - NCT07150715RecruitingPhase 2
Radioactive drug plus precise radiation for recurrent prostate cancer
This trial tests a powerful radioactive drug (either alpha or beta) combined with precise radiation to treat prostate cancer that has come back in a few spots outside the prostate. It may help men whose cancer is still hormone-sensitive and has not spread widely.
Los Angeles, CaliforniaAges 18 years+ - 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 - NCT07054346RecruitingPhase 1
Radioactive drugs before prostate surgery for high-risk prostate cancer
This trial compares two radioactive drugs (177Lu-PSMA-617 and 225Ac-PSMA-617) given before prostate removal surgery in men with high-risk prostate cancer that has not spread far. The goal is to see which drug is better at shrinking the tumor and reducing the chance of cancer coming back.
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+ - NCT07005154RecruitingPhase 2
Study of ASP5541 for metastatic prostate cancer
This study tests an experimental drug called ASP5541 for men with metastatic prostate cancer (either hormone-sensitive or castration-resistant). It aims to see if the drug can slow cancer growth and improve outcomes when added to standard hormone therapy.

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.
