Recruiting studies in California
- NCT05869682RecruitingPhase 2
Bright light therapy for fatigue and depression in prostate cancer
This Phase 2 study tests whether a “bright white light” intervention can reduce cancer-related fatigue and depression in people with advanced prostate cancer receiving hormone-based treatment. If it works, it could improve day-to-day well-being while you’re on standard cancer therapies.
Duarte, CaliforniaAges 60 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+ - 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+ - NCT06267729RecruitingPhase 1/Phase 2
A new cell therapy for advanced prostate cancer
This trial tests a new cell therapy (AZD0754) for metastatic prostate cancer that has stopped responding to standard hormone therapy and chemotherapy. It’s looking for people whose cancer has gotten worse despite prior treatments, and who are still in fairly good health.
Duarte, CaliforniaAges 18–130 - NCT06288113RecruitingPhase 2
Re-treatment with 177Lu-PSMA-617 for prostate cancer
This trial tests if a second round of a targeted radiation therapy (177Lu-PSMA-617) can help men whose prostate cancer has returned after a successful first treatment. It is for men whose cancer has stopped responding to hormone therapy and chemotherapy, and whose PSA levels have risen again after a prior good response to this drug.
Los Angeles, CaliforniaAges Any age - NCT06353386RecruitingPhase 1/Phase 2
Opevesostat combinations for advanced prostate cancer
This study tests a new drug called opevesostat, alone or combined with other treatments, for men with advanced prostate cancer that has spread and stopped responding to hormone therapy. It aims to see if it can help control the cancer.
Los Angeles, CaliforniaAges 18 years+ - NCT06470243RecruitingPhase 3
Adding carboplatin to cabazitaxel for advanced prostate cancer
This study tests whether adding a chemotherapy drug called carboplatin to another chemotherapy called cabazitaxel works better than cabazitaxel alone for men with advanced prostate cancer that has spread and no longer responds to hormone therapy. All participants must have already had docetaxel chemotherapy.
Long Beach, CaliforniaAges 18 years+ - NCT03972657RecruitingPhase 1/Phase 2
Testing a new prostate and kidney cancer drug with immunotherapy
This early trial tests whether REGN5678 (nezastomig) is safe and how well it works, either by itself or with an immunotherapy drug (cemiplimab). It targets adults with metastatic castration-resistant prostate cancer and certain metastatic kidney cancers that have already been treated.
Santa Monica, CaliforniaAges 18 years+ - NCT06526299RecruitingPhase 2
Higher dose of targeted radiation for prostate cancer with low PSMA levels
This trial tests a higher dose of a radioactive drug (177Lu-PSMA-617) for men whose prostate cancer has spread and does not produce much of a protein called PSMA on scans. The goal is to see if a stronger dose can work better than the standard dose.
Sylmar, CaliforniaAges 18 years+ - NCT06615752RecruitingPhase 1/Phase 2
Green tea and quercetin with chemo for prostate cancer
This trial tests whether adding green tea extract and quercetin (a plant compound) to standard chemotherapy (docetaxel) can help men with advanced prostate cancer that has stopped responding to hormone therapy. The goal is to see if this combination is safe and works better than chemo alone.
Los Angeles, CaliforniaAges 18 years+ - NCT06706921RecruitingPhase 4
Predicting treatment success with PET scans in prostate cancer
This study looks at whether a special PET scan can help predict how well a targeted radiation therapy (LuPSMA) works in men with advanced prostate cancer that has spread. You would get several PET scans before and after treatment to see if the scan results can forecast your outcome.
Los Angeles, CaliforniaAges 18 years+ - NCT06879041RecruitingPhase 1
Study of a radiation drug for advanced prostate cancer
This trial tests a new drug that delivers radiation directly to cancer cells. It is for men with metastatic castration-resistant prostate cancer that has progressed after other treatments.

A study for men with advanced prostate cancer on a specific clinical trial
This study looks at men with metastatic castration-resistant prostate cancer who are already taking part in the SYNGERY-201 clinical trial. The goal is to understand how treatments work and how to best support patients.
San Francisco, CaliforniaAges 18 years+ - NCT07103018RecruitingPhase 1
Study of KTX-2001 for men with advanced prostate cancer
This trial tests a new drug called KTX-2001, possibly combined with another drug (darolutamide), for men whose prostate cancer has spread and stopped responding to standard hormone treatments. The goal is to see if it can help shrink tumors or slow the cancer's growth.
San Francisco, CaliforniaAges 18 years+ - NCT07111507RecruitingPhase 2
Tarlatamab for advanced prostate cancer
This trial tests a drug called tarlatamab for people with advanced prostate cancer that has a specific protein (DLL3) on their tumor cells. The goal is to see if tarlatamab can help shrink or slow the cancer.

What taking part in a metastatic castration-resistant 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.
