Recruiting studies in California
- NCT07213674RecruitingPhase 3
A study of xaluritamig plus abiraterone for prostate cancer
This trial tests a new combination of two drugs (xaluritamig plus abiraterone) for men with a type of advanced prostate cancer that is no longer responding to hormone therapy but has not yet been treated with chemotherapy. The goal is to see if this combination works better than the standard options your doctor might choose.
Duarte, CaliforniaAges 18 years+ - NCT05805371RecruitingPhase 1
PSCA CAR-T cells with or without radiation for prostate cancer
This Phase 1 study tests a prostate cancer treatment made of PSCA-targeted CAR-T cells, with or without radiation, to help control advanced prostate cancer. It aims to find a safe treatment approach and see how well it works in people whose cancer has PSCA.
Duarte, CaliforniaAges 18 years+ - NCT06844383RecruitingPhase 2
Talazoparib with or without enzalutamide for prostate cancer after prior treatment
This study tests a drug called talazoparib, either alone or combined with enzalutamide, in people with prostate cancer that has spread and has a specific genetic change. The goal is to see if this treatment can help control the cancer after previous therapies have stopped working.
Duarte, 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.
San Diego, CaliforniaAges 18 years+ - NCT06925737RecruitingPhase 3
Study of I-DXd for metastatic prostate cancer
This study tests a new drug called Ifinatamab Deruxtecan (I-DXd) for people with metastatic prostate cancer that has stopped responding to hormone therapy. It may help by targeting and destroying cancer cells in a different way.
Duarte, 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+ - NCT04423211RecruitingPhase 3
Surgery-recovered prostate cancer treated with PET-guided radiation
This trial tests whether adding targeted radiation guided by a PET scan (along with hormone therapy) can improve outcomes for prostate cancer that has come back after surgery. The PET scan helps doctors look for spots outside the usual radiation area so treatment can be tailored.
Arroyo Grande, CaliforniaAges 18 years+ - NCT06842498RecruitingPhase 2
FG-3246 for advanced prostate cancer
This trial tests a new drug called FG-3246, which targets a protein (CD46) on prostate cancer cells. It's for men with advanced prostate cancer that has spread and stopped responding to standard hormone therapy, and who have had limited prior treatments.
Los Angeles, 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+ - 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+ - NCT05519449RecruitingPhase 1
Testing a PSMA-targeting treatment for advanced prostate cancer
This Phase 1 trial tests JANX007 in men with metastatic castration-resistant prostate cancer (cancer that keeps growing despite standard hormone treatment). It aims to find a safe dose and see whether the treatment can shrink tumors or slow progression.
Los Angeles, CaliforniaAges 18–100 - 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+ - NCT06134232RecruitingPhase 2
Extra sipuleucel-T after Provenge for prostate cancer
This trial tests whether adding one extra infusion of sipuleucel-T (the same drug as Provenge) after the standard three doses can help men with advanced prostate cancer that no longer responds to hormone therapy. It is for men who have already finished their three Provenge infusions and have mild or no symptoms.
Duarte, CaliforniaAges 18 years+ - NCT04986423RecruitingPhase 2
Add ZEN003694 to enzalutamide for resistant prostate cancer
This Phase 2 study tests whether adding ZEN003694 to enzalutamide works better than enzalutamide alone in men whose prostate cancer has spread and is no longer controlled by hormone lowering treatments. It focuses on people who either did not respond well to abiraterone (poor responders) or did respond (responders), then compares outcomes between treatment groups.
Los Angeles, CaliforniaAges 18 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+ - 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.
Palo Alto, CaliforniaAges 18 years+ - NCT06228053RecruitingPhase 2
Study of SX-682 plus enzalutamide for men with advanced prostate cancer

What taking part in a metastatic 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.
