La Jolla, CaliforniaAges 18 years+ - 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+ - 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+ - NCT07223385RecruitingPhase 2
Heart health check for prostate cancer patients on ARPI therapy
This trial is for men with advanced prostate cancer who are taking ARPI therapy. It offers a special heart health consultation to help manage the increased heart risk that can come with these powerful cancer treatments.
Los Angeles, CaliforniaAges 45 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+ - NCT07145177RecruitingPhase 1
Lu177-PSMA with liver treatment for advanced prostate cancer
This trial tests a targeted radiation drug (Lu177-PSMA) combined with procedures that treat liver tumors directly (like ablation or radiation). It is for men with prostate cancer that has spread to the liver and is no longer responding to hormone therapy. The goal is to see if this combination works better together.
San Francisco, 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 - NCT07111507RecruitingPhase 2
Tarlatamab for advanced prostate cancer
This trial tests a drug called tarlatamab for people with advanced prostate cancer that has a specific protein (DLL3) on their tumor cells. The goal is to see if tarlatamab can help shrink or slow the cancer.
San Diego, CaliforniaAges 18 years+ - NCT07103018RecruitingPhase 1
Study of KTX-2001 for men with advanced prostate cancer
This trial tests a new drug called KTX-2001, possibly combined with another drug (darolutamide), for men whose prostate cancer has spread and stopped responding to standard hormone treatments. The goal is to see if it can help shrink tumors or slow the cancer's growth.
San Francisco, CaliforniaAges 18 years+ - NCT07059884Recruiting

What taking part in a prostate 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.
