Recruiting studies in California
- NCT07005154RecruitingPhase 2
Study of ASP5541 for metastatic prostate cancer
This study tests an experimental drug called ASP5541 for men with metastatic prostate cancer (either hormone-sensitive or castration-resistant). It aims to see if the drug can slow cancer growth and improve outcomes when added to standard hormone therapy.

Fountain Valley, 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+ - 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.

Los Angeles, CaliforniaAges 18 years+ - NCT06136650RecruitingPhase 3
Study of a new drug for advanced prostate cancer
This study tests a new oral drug called opevesostat against another standard hormone therapy for men with advanced prostate cancer that has spread and is no longer controlled by a first hormone therapy. It's for men who have not had chemotherapy for this stage and who have not used a PARP inhibitor or chose not to.
Irvine, CaliforniaAges 18 years+ - NCT06764485RecruitingPhase 3
Comparing a new drug to standard therapy for advanced prostate cancer
This trial tests a new medicine (BMS-986365) against the doctor's choice of standard therapy for men with metastatic castration-resistant prostate cancer. It aims to see which treatment works better and is safer.
Anaheim, CaliforniaAges 18 years+ - NCT06520345RecruitingPhase 3
A new treatment for advanced prostate cancer that has stopped responding to hormone therapy
This trial tests a new radioactive drug (177Lu-TLX591) plus standard care against standard care alone for men with metastatic castration-resistant prostate cancer that has progressed on an androgen receptor pathway inhibitor. The goal is to see if this targeted radiation can help control the cancer.
Orange, CaliforniaAges 18 years+ - NCT07581184RecruitingPhase 1
Targeted Radioactive Therapy for Advanced Prostate Cancer
This Phase 1 trial tests a new radioactive treatment called [225Ac]Ac-AKY-2519 in men with advanced prostate cancer that has spread and stopped responding to hormone therapy. The drug carries radioactivity directly to cancer cells to try to shrink tumors and slow disease progression.
Irvine, CaliforniaAges 18 years+ - NCT04038502RecruitingPhase 2
Testing carboplatin or olaparib for gene-linked prostate cancer
This Phase 2 study tests whether carboplatin or olaparib can help people with prostate cancer that has certain DNA repair gene changes. It’s designed for advanced (metastatic) prostate cancer that is growing despite standard hormone-blocking treatment.
West Los Angeles, CaliforniaAges 18 years+ - 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.
Duarte, CaliforniaAges 18 years+ - NCT04606446RecruitingPhase 2
Study drug for ER-positive, HER2-negative cancers after treatment
This Phase 2 study tests a new Pfizer medicine (PF-07248144) for certain advanced or metastatic breast, prostate, or lung cancers that have not responded to standard treatment or no standard options exist. You may qualify if you have a specific tumor type and a limited number of prior cancer treatments, and if your body functions (blood, liver, kidneys) and heart rhythm meet safety limits.
San Francisco, CaliforniaAges 18 years+ - NCT04729114RecruitingPhase 1
Safety and dose test of PRL-02 shot for advanced prostate cancer
This Phase 1 study tests how safe PRL-02 depot (an injection) is and finds the best dose for men with advanced prostate cancer. It may help determine a new treatment option for cancers that have spread or are getting worse despite standard care.
Anaheim, CaliforniaAges 18 years+ - NCT04787744RecruitingPhase 2/Phase 3
Test standard prostate cancer treatment with or without targeted spot radiation
This study tests whether adding targeted local treatment (like radiation to a few spots seen on scans) improves outcomes for some people with limited (oligometastatic) prostate cancer. It compares standard systemic therapy alone versus standard therapy plus PET-scan–guided spot treatment.
West Los Angeles, CaliforniaAges 18 years+ - NCT04868604RecruitingPhase 1/Phase 2
Copper PSMA scan and treatment for prostate cancer in men on low testosterone
This trial tests a PSMA-targeted copper medicine used after a special PSMA PET/CT scan to find and treat prostate cancer that has spread. It’s for men whose testosterone is already very low and whose cancer is growing despite hormone-blocking medicines like enzalutamide or abiraterone.
Stanford, CaliforniaAges 18 years+ - NCT06844383RecruitingPhase 2
Talazoparib with or without enzalutamide for prostate cancer after abiraterone
This trial tests whether a drug called talazoparib, alone or combined with enzalutamide, can help people with a certain type of advanced prostate cancer that has stopped responding to abiraterone. It is for those who have a specific genetic change (HRR mutation) in their tumor.
Duarte, CaliforniaAges 18 years+ - NCT04969315RecruitingPhase 1/Phase 2
Drug TT-10 and TT-4 for advanced solid tumors
This early-phase trial tests two investigational drugs—TT-10 and TT-4—alone and together in people with advanced solid cancers. The study is designed to find safe doses and see if the treatment can shrink tumors or slow cancer growth.
Los Angeles, CaliforniaAges 18 years+ - NCT05107674RecruitingPhase 1

This Phase 1 study tests NX-1607 in adults with advanced cancers that are hard to treat with standard care. It focuses on safety and early signs of how well the drug may work in specific cancer types.
Los Angeles, CaliforniaAges 18 years+ - NCT05223803RecruitingPhase 2
Study radiation for early metastatic prostate cancer
This Phase 2 trial tests a radiation-focused approach for people with newly diagnosed (de novo) prostate cancer that has spread to a small number of spots, especially in bone. It aims to see how well the treatment controls the cancer while keeping side effects manageable.
La Jolla, CaliforniaAges 18 years+ - NCT05396872Recruiting
Decision-making study about gene testing for advanced prostate cancer
This study looks at how Veterans with advanced prostate cancer make decisions about gene testing and possible targeted treatments, and how patients and caregivers understand the information. It may help by improving decision support for people facing germline and tumor testing choices.
San Francisco, CaliforniaAges 18 years+ - NCT05398302RecruitingPhase 1
Biopsies during prostate cancer treatment to study resistance
This early study uses image-guided biopsies (small tissue samples taken with imaging) to learn why metastatic prostate cancer may stop responding to PSMA radioligand therapy. The results may help doctors understand resistance and improve future treatments.

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.
