Los Angeles, CaliforniaAges 55–85 - NCT06437574RecruitingPhase 2
Cholesterol-lowering and immune response in prostate cancer
This trial tests whether taking a daily cholesterol-lowering medication (Vytorin or ezetimibe) can boost your immune system to help fight prostate cancer. It is for men with low- or intermediate-risk prostate cancer who are on active surveillance and planning a biopsy.
Los Angeles, CaliforniaAges 18 years+ - NCT06440005RecruitingPhase 1
Testing AGX101 for advanced solid tumors
This study tests a new drug called AGX101 for people with advanced solid tumors that have not responded to other treatments. The goal is to see if it is safe and if it can shrink tumors or slow their growth.
Los Angeles, 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+ - NCT06242470RecruitingPhase 1
Study of MGC026 for advanced solid tumors
This trial tests a new drug called MGC026 that targets a protein called B7-H3 on cancer cells, aiming to shrink or slow different advanced solid tumors. It is an early-phase study to find the right dose and check safety.
Los Angeles, CaliforniaAges 18 years+ - NCT06216249RecruitingPhase 2
Flexible dosing of Lu-PSMA for advanced prostate cancer
This trial tests a flexible dosing schedule of a targeted radiation drug (Lu-PSMA) for men with metastatic prostate cancer that has stopped responding to hormone therapy and chemotherapy. It aims to see if adjusting the treatment schedule can improve outcomes while reducing side effects.
Los Angeles, CaliforniaAges 18 years+ - NCT06171139Recruiting
Genetic counseling tool for Black men with prostate cancer
This study tests a new tool to help Black or African American men with prostate cancer understand genetic testing options. The goal is to improve counseling and decision-making about tumor genetic testing.
San Francisco, CaliforniaAges 18 years+ - NCT06178354Recruiting
Freezing or ultrasound for early prostate cancer
This trial is testing whether freezing (cryotherapy) or using high-frequency ultrasound (HIFU) to destroy only the cancer spots in the prostate is safe and effective for men with early-stage prostate cancer. It's a less invasive option that targets just the tumor, not the whole prostate.
Sacramento, 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+ - NCT03452774Recruiting
AI matches your cancer tests to possible treatment trials
This trial uses an AI system to help match people with certain cancer types and specific tumor test results (like gene or protein markers) to relevant clinical trials. It may help you and your doctor find studies that fit your cancer biology faster.
Duarte, CaliforniaAges Any age - 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+ - 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+ - NCT05948657Recruiting
PSMA PET-CT scan for men on prostate cancer surveillance
This study checks whether a special prostate scan called PSMA PET-CT (along with standard monitoring scans) can help guide care while you are on “active surveillance” instead of immediate treatment. It may help doctors track low-risk prostate cancer changes more accurately over time.

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.
