Recruiting studies in California
- 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+ - NCT04945642Recruiting
Radiation combination therapy for intermediate to high-risk prostate cancer
This trial studies a combination of two radiation types—high-dose-rate brachytherapy and stereotactic body radiotherapy—to treat certain intermediate- to high-risk prostate cancers. It may help by aiming radiation closely at the prostate while also targeting the cancer from outside the body.
Los Angeles, CaliforniaAges 18 years+ - NCT05751434RecruitingPhase 2
Exercise therapy for prostate cancer patients on active surveillance
This trial tests whether an exercise program can help men with early-stage prostate cancer who are being monitored instead of treated. If you are not very active now, you may be able to join a structured exercise plan to see if it improves your health and cancer signs.
Durate, CaliforniaAges 18 years+ - NCT03821246RecruitingPhase 2
Atezolizumab and other drugs before prostate surgery for high-risk cancer
This Phase 2 trial tests whether giving immunotherapy (atezolizumab) plus another drug before surgery can shrink or control high-risk localized prostate cancer. The goal is to improve outcomes by treating the cancer early, before radical prostatectomy.
San Francisco, 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+ - NCT05113537RecruitingPhase 1/Phase 2
Abemaciclib before PSMA cancer therapy for advanced prostate cancer
This trial tests whether taking abemaciclib before a PSMA-targeted radioligand can help people with advanced, treatment-resistant prostate cancer. The goal is to improve how well the PSMA therapy works while staying safe.
San Francisco, CaliforniaAges 18 years+ - NCT04734730RecruitingPhase 2
Talazoparib plus hormone therapy for metastatic prostate cancer
This trial tests whether talazoparib added to standard hormone therapy (ADT), along with abiraterone, can better control metastatic prostate cancer that hasn’t progressed despite starting hormone treatment. It may help people live longer and delay cancer worsening.
Duarte, CaliforniaAges 18 years+ - NCT05946213RecruitingPhase 3
Shorter radiation treatment for high-risk prostate cancer
This trial tests whether a shorter course of radiation works as well as the usual longer course for people with high-risk prostate cancer. The goal is to keep cancer control while possibly reducing treatment time and inconvenience.
Orange, CaliforniaAges 18 years+ - NCT05665738Recruiting
Two-visit HDR radiation to treat early prostate cancer
This study tests a radiation treatment delivered in two fractions (two sessions) as the only treatment for certain early-stage prostate cancers. It may help you avoid other treatments, like hormone therapy, depending on whether your cancer and health history fit the study.
San Francisco, CaliforniaAges 18 years+ - NCT05001477Recruiting
Registry for men receiving TULSA-PRO prostate treatment
This is a study registry that collects information from men who are going to receive TULSA-PRO treatment. It helps researchers understand how the treatment is used and what outcomes people experience.
West Hills, CaliforniaAges 18 years+ - NCT06173362RecruitingPhase 2
Abiraterone or darolutamide for advanced prostate cancer
This study is comparing two drugs, abiraterone and darolutamide, to see how well they work for advanced prostate cancer. You might join if your cancer has spread and your doctor agrees these treatments could help.
Sacramento, 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+ - NCT06931340RecruitingPhase 3
Adding chemo to hormone therapy for advanced prostate cancer
This trial is for men with metastatic prostate cancer that has already spread beyond the pelvis. It tests whether adding a chemotherapy drug (docetaxel) to the usual hormone therapy plus apalutamide can help control the cancer better than hormone therapy alone.
Dublin, 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+ - NCT06067269RecruitingPhase 2
Hormone therapy and precise radiation for intermediate-risk prostate cancer
This trial tests whether giving a short course of hormone therapy (apalutamide) along with targeted, high-dose radiation (SBRT) is safe and effective for men with a specific type of intermediate-risk prostate cancer. You may benefit if you fit the exact risk and test criteria.
Los Angeles, CaliforniaAges 18 years+ - NCT03933670RecruitingPhase 2
MRI scan with special sugar to monitor prostate cancer on surveillance
This study uses a special MRI scan using “hyperpolarized” labeled pyruvate (a sugar-like substance) to see how prostate cancer may be behaving in people who are on active surveillance. It may help researchers monitor cancer without immediate treatment, by spotting changes earlier.
San Francisco, CaliforniaAges 18 years+ - NCT06995053Recruiting
Prostate cancer radiation therapy with motion monitoring
This trial tests a precise radiation technique for prostate cancer that tracks the prostate during treatment. It aims to deliver higher radiation doses more safely, which may improve outcomes.
Los Angeles, CaliforniaAges 18 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+ - NCT03678025RecruitingPhase 3
Standard treatment for metastatic prostate cancer, with or without local treatment
This Phase 3 trial studies whether using the usual medicines for metastatic prostate cancer, plus a definitive local treatment to the prostate, improves outcomes. It may help determine if treating the prostate directly can benefit people whose cancer has not worsened after initial hormone-based treatment.
Marysville, 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+ - NCT07745361RecruitingPhase 2
Study of MRT-2359 with apalutamide for prostate cancer
This trial tests a new oral drug, MRT-2359, combined with apalutamide (a standard hormone therapy) in men with a specific type of prostate cancer that has stopped responding to hormone treatment. The goal is to see if the combination can slow or stop the cancer's growth.
Los Angeles, CaliforniaAges 18 years+ - NCT05806515RecruitingPhase 2
Carboplatin before surgery for high-risk BRCA prostate cancer
This trial tests giving the chemotherapy drug carboplatin before surgery to treat people with high-risk prostate cancer and an inherited BRCA1 or BRCA2 gene change. The goal is to shrink or control the cancer before an operation and improve outcomes.
Irvine, CaliforniaAges 18 years+ - NCT06801236RecruitingPhase 1
A new drug for advanced prostate cancer that has stopped responding to treatment
This early-phase trial tests a new study drug called ACE-232 for men with advanced prostate cancer that has stopped responding to standard hormone therapy and chemotherapy. It aims to see if the drug is safe and may help slow the cancer.
La Jolla, CaliforniaAges 18 years+ - NCT05691465RecruitingPhase 2
Radiation drug for metastatic prostate cancer with neuroendocrine cells
This Phase 2 study tests whether a radioactive medicine called lutetium Lu 177 dotatate is safe and effective for metastatic prostate cancer that has neuroendocrine features. It also checks whether patients’ scans show the cancer absorbs the drug (a requirement to start treatment).

What taking part in a prostate 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.
