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+ - 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+ - 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+ - NCT06609005RecruitingPhase 1/Phase 2
Study of INV-9956 for advanced prostate cancer
This trial tests a new drug called INV-9956 in men with advanced prostate cancer that no longer responds to hormone therapy and has spread to other parts of the body. It aims to see if the drug is safe and effective.
Orange, CaliforniaAges 18 years+ - NCT06615752RecruitingPhase 1/Phase 2
Green tea and quercetin with chemo for prostate cancer

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.
