Recruiting studies in California
- 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.
La Jolla, 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+ - 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+ - NCT06778863RecruitingPhase 1
A study of CLSP-1025 for adults with certain solid tumors
This trial tests a new drug called CLSP-1025 for people with advanced solid tumors that have a specific change in the p53 gene (R175H). The drug targets this change to help fight the cancer.
Los Angeles, CaliforniaAges 18 years+ - NCT06613100RecruitingPhase 1
Xaluritamig before prostate surgery for high-risk prostate cancer
This study tests an experimental drug called xaluritamig given before surgery for men with localized prostate cancer that is intermediate or high risk. The goal is to see if it can help shrink the cancer before the prostate is removed.
San Francisco, 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.
Lancaster, CaliforniaAges 18 years+ - NCT06391034RecruitingPhase 2
MRI scan with pyruvate for prostate cancer
This trial uses a special MRI scan (with hyperpolarized pyruvate, a naturally occurring substance) to look at prostate cancer in more detail. It aims to help doctors understand how the cancer is responding to treatment or how it might behave.
San Francisco, CaliforniaAges 18 years+ - NCT06257693RecruitingPhase 1
Prostate cancer implant trial before prostate removal surgery
This trial tests a new enzalutamide implant (Enolen) placed in the prostate before surgery to see if it helps treat early prostate cancer. It is for men who are already planning to have their prostate removed.
Fresno, CaliforniaAges 21 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+ - NCT06056830RecruitingPhase 3
PET scan for high-risk prostate cancer before surgery
This trial uses a special PET scan to find prostate cancer cells before surgery. It may help doctors see where the cancer is located and if it has spread.
Los Angeles, 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+ - 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+ - 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.
Fremont, CaliforniaAges 18 years+ - NCT05888532RecruitingPhase 1/Phase 2
Testing a copper-based scan and treatment in advanced cancers
This Phase 1/2 trial studies a copper-labeled medicine called 64Cu-GRIP B in people with advanced, metastatic cancers. It may help doctors see where cancer is and how well the drug works, especially alongside immune checkpoint therapy for some cancer types.
San Francisco, CaliforniaAges 18 years+ - NCT05832086RecruitingPhase 2
Fasting-mimicking diet to improve prostate cancer and metabolism
This trial tests whether an intermittent, fasting-like diet can help control metastatic prostate cancer and improve metabolic health in men on hormone therapy. Participants follow a specific diet plan and are monitored by the study team.
Duarte, CaliforniaAges Any age - 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.
Carmichael, 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+ - NCT05766371RecruitingPhase 2
Immunotherapy plus targeted radiation for advanced prostate cancer
This study combines two treatments: pembrolizumab, which helps your immune system fight cancer, and a targeted radioactive medicine (177Lu-PSMA-617) that seeks out and damages prostate cancer cells. It may help men whose prostate cancer has spread despite initial hormone therapy.
San Francisco, 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).
Duarte, CaliforniaAges 18 years+ - NCT05665738Recruiting
Two high-dose radiation treatments for early prostate cancer
This trial tests a shorter course of high-dose radiation therapy for prostate cancer that hasn't spread. It aims to make treatment more convenient while keeping it effective.
San Francisco, 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 - NCT05422911RecruitingPhase 2
Abiraterone, enzalutamide, or apalutamide for early castration prostate cancer
This Phase 2 trial tests whether abiraterone, enzalutamide, or apalutamide can work better (or differently) in men with prostate cancer that is considered “castration-sensitive.” It compares these hormone-blocking treatments to find an approach that controls the cancer more effectively and safely.
Los Angeles, CaliforniaAges 18 years+ - NCT05334069Recruiting
Blood test study for early cancer detection in patients
This study collects blood from people with cancer and people without cancer (or with possible cancer) to test whether new blood tests can detect cancer earlier. Your blood samples help researchers evaluate how well these tests work.
Arroyo Grande, CaliforniaAges 40–75 - 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.

What taking part in a prostate cancer (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.
