Recruiting studies in California
- NCT04363164RecruitingPhase 2
Testosterone then enzalutamide to stop prostate cancer spread
This Phase 2 trial tests whether giving testosterone first, then enzalutamide (a prostate cancer hormone-blocking pill), can slow or prevent worsening metastatic prostate cancer. It is designed for men whose cancer progressed despite ongoing hormone-suppression treatment.
San Diego, CaliforniaAges 18–90 - NCT04221542RecruitingPhase 1
AMG 509 for advanced, hormone-resistant prostate cancer
This trial tests AMG 509, a study drug, in men with metastatic castration-resistant prostate cancer (cancer that keeps growing despite lowering testosterone). It’s for people whose cancer has progressed after certain hormone tablets and possibly chemotherapy, aiming to shrink tumors and control the disease safely.
Fullerton, CaliforniaAges 18 years+ - NCT04038502RecruitingPhase 2
Comparing carboplatin and olaparib for prostate cancer with BRCA gene changes
This study compares two treatments for prostate cancer that has spread and has specific gene changes (BRCA or related genes). It aims to see which treatment works better for people whose cancer has stopped responding to other hormone therapies.
West Los Angeles, CaliforniaAges 18 years+ - NCT03972657RecruitingPhase 1/Phase 2
Testing a new prostate and kidney cancer drug with immunotherapy
This early trial tests whether REGN5678 (nezastomig) is safe and how well it works, either by itself or with an immunotherapy drug (cemiplimab). It targets adults with metastatic castration-resistant prostate cancer and certain metastatic kidney cancers that have already been treated.
Santa Monica, CaliforniaAges 18 years+ - NCT03460977RecruitingPhase 1
Mevrometostat trial for hormone-resistant prostate cancer
This Phase 1 study tests mevrometostat (PF 06821497) in people with castration-resistant prostate cancer to see if it’s safe and how the body responds to it. It may be an option if your cancer is no longer controlled by hormone therapy and your organ health tests are within limits.
Anaheim, 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 - 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+ - NCT06084338RecruitingPhase 2
Focused Radiation Therapy Without Hormone Therapy for Advanced Prostate Cancer
This trial tests whether giving focused radiation to many cancer spots (SBRT) can work without using testosterone-blocking hormone therapy. It is for men whose prostate cancer has spread and is no longer responding to low testosterone, and who have already tried one of the newer hormone drugs.
West Los Angeles, CaliforniaAges 18 years+ - NCT07569926RecruitingPhase 4
Fluciclovine PET scan for prostate cancer recurrence detection
This study tests whether a newer type of imaging scan (called fluciclovine PET) can find where prostate cancer has come back when an earlier scan (PSMA PET) didn't show clear results. The goal is to help doctors better plan treatment for men whose cancer has returned after surgery or radiation.
San Diego, CaliforniaAges 18 years+ - NCT05983432RecruitingPhase 1
Study of BL-B01D1 for advanced lung and other solid tumors
This trial tests an experimental drug called BL-B01D1 for people with several types of advanced solid tumors, especially non-small cell lung cancer and breast cancer. It's designed for those whose cancer has continued to grow after standard treatments.
Beverly Hills, CaliforniaAges 18 years+ - NCT06235697RecruitingPhase 3
Hormone therapy with or without lymph node radiation for prostate cancer
This trial tests combining hormone therapy with different types of radiation (including high-dose external beam and brachytherapy) for men with prostate cancer that has a higher chance of coming back. It aims to see if adding radiation to the lymph nodes helps control the cancer better.
Redwood City, CaliforniaAges 18 years+ - NCT06855277RecruitingPhase 3
AAA817 with hormone therapy for advanced prostate cancer
This trial tests a new combination treatment (AAA817 plus a hormone therapy) against standard care for men with advanced PSMA-positive prostate cancer that has spread and stopped responding to a previous hormone therapy. It may be an option if you haven't had certain prior treatments.
Orange, CaliforniaAges 18–100 - NCT06136624RecruitingPhase 3
Comparing a new drug to standard hormone therapy for advanced prostate cancer
This trial tests a new pill, opevesostat, against other hormone treatments for men with metastatic castration-resistant prostate cancer that has progressed after previous therapies. It aims to see which approach works better.
Orange, CaliforniaAges 18 years+ - NCT05939414RecruitingPhase 3
Study of radioactive drug for prostate cancer that has spread a little
This study tests a radioactive drug (177Lu-PSMA-617) compared to no immediate treatment in men with prostate cancer that has returned and spread to a few spots (oligometastatic). It aims to see if this treatment delays the spread of cancer and improves outcomes.
Los Angeles, CaliforniaAges 18–100 - NCT07114601RecruitingPhase 1
Study of LY4257496 for people with GRPR-positive solid tumors
This trial tests a new drug, LY4257496, in people with certain types of cancer that have a protein called GRPR on their cells. The study aims to see if the drug can help shrink tumors or slow the cancer's growth.
Duarte, 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.

What taking part in a castration resistant prostatic 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.

- Do I have to live in California to take part?
- Not necessarily. These studies have a site in California, but eligibility is about your health, not your address — some people travel to take part, and a few studies reimburse travel. The study team can tell you what's required.
- Does it cost anything to join a castration resistant prostatic cancer trial?
- Using Clin2 is always free. Many trials cover the study treatment and related visits; some reimburse travel. The study team explains exactly what's covered before you decide.
