Recruiting studies in California
- NCT06632977RecruitingPhase 2
Matching targeted treatments to your prostate cancer's genetics
This trial is testing whether matching your cancer's specific genetic changes to a targeted treatment can help control metastatic prostate cancer that has stopped responding to standard hormone therapy and chemotherapy. You may receive a drug, a radioactive treatment, or a combination based on your tumor's molecular profile.
Chico, 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.
Lancaster, CaliforniaAges 18 years+ - NCT07080242RecruitingPhase 1
Study of a new drug for small cell lung cancer and neuroendocrine tumors
This trial tests a new drug called BL-M14D1 for people with certain types of advanced lung cancer or neuroendocrine tumors that have stopped responding to other treatments. It may be an option if your cancer has a specific marker called DLL3.
Los Angeles, 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+ - NCT06592924RecruitingPhase 3
Adding chemo to hormone therapy for prostate cancer with slow PSA drop
This trial tests if adding docetaxel chemotherapy helps men whose PSA hasn't dropped enough after at least 6 months of standard hormone therapy (ADT) plus an ARPI pill (like abiraterone or enzalutamide) for metastatic prostate cancer that still responds to hormones.
Anaheim, CaliforniaAges 18 years+ - NCT06629779RecruitingPhase 3

Palo Alto, 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+ - 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
This trial tests whether adding the drug SX-682 to enzalutamide can help men whose prostate cancer has stopped responding to other hormone treatments. You may be eligible if your cancer is growing despite treatment with abiraterone, darolutamide, apalutamide, or enzalutamide.
Los Angeles, CaliforniaAges 18 years+ - NCT07287150RecruitingPhase 2
Inavolisib for metastatic castration-resistant prostate cancer

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.
