Recruiting studies in California
- 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.
Palo Alto, CaliforniaAges 18 years+ - NCT07140900RecruitingPhase 1
Study of xaluritamig combined with hormone therapy for advanced prostate cancer
This trial tests a new drug, xaluritamig, given with standard hormone therapy for men with prostate cancer that has spread to other parts of the body (metastatic) and is still sensitive to hormone therapy. It aims to see if the combination is safe and works better than hormone therapy alone.
San Francisco, CaliforniaAges 18 years+ - 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+ - NCT06022029RecruitingPhase 1
Study of injected ONM-501 alone or with cemiplimab for advanced cancers
This trial tests an injected study drug (ONM-501) alone or with another drug (cemiplimab) for people with advanced solid tumors or lymphomas that haven't responded to other treatments. It aims to find a safe dose and see if the combination helps shrink or control the cancer.
Los Angeles, CaliforniaAges 18 years+ - NCT06771219RecruitingPhase 1
Testing SLV-154 for advanced cancers
This trial tests a new drug called SLV-154 for people whose advanced cancer has not responded to standard treatments. The goal is to see if SLV-154 can shrink tumors or slow cancer growth.
Newport Beach, CaliforniaAges 12 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+ - NCT05557045RecruitingPhase 1
Trial of an oral pill for MAPK-driven advanced solid tumors
This Phase 1 study tests an oral investigational medicine (JZP815) to see how safe it is, the best dose, and whether it can shrink tumors. It’s for adults with advanced or metastatic solid cancers that have a specific MAPK pathway genetic change.
Los Angeles, CaliforniaAges 18 years+ - NCT05394103RecruitingPhase 1/Phase 2
Testing a targeted pill for hard-to-treat solid tumors
This trial tests a new medicine (Q901) that targets a specific cell-control pathway to treat advanced cancers that have stopped responding to standard care. It’s mainly for people with certain solid tumor cancers, aiming to see whether the drug can shrink tumors or control disease.
Los Angeles, CaliforniaAges 18 years+ - NCT05673148RecruitingPhase 3
Ablation treatment plus usual therapy for limited metastatic bowel cancer
This study tests whether adding “total ablation” (carefully destroying all visible small tumors using surgery, heat/cold treatment, and/or targeted radiation) to standard chemotherapy improves outcomes for people with limited spread of colorectal cancer. It may help by aiming to eliminate all known metastatic spots while you continue usual cancer treatment.
Beverly Hills, CaliforniaAges 18 years+ - NCT06991556RecruitingPhase 2
Testing JSB462 plus abiraterone for advanced prostate cancer
This trial tests a new drug called JSB462 combined with abiraterone in men with prostate cancer that has spread to other parts of the body and is still responding to hormone therapy. The goal is to see if this combination works better than current treatments.
La Jolla, CaliforniaAges 18 years+ - NCT06842498RecruitingPhase 2
FG-3246 for advanced prostate cancer
This trial tests a new drug called FG-3246, which targets a protein (CD46) on prostate cancer cells. It's for men with advanced prostate cancer that has spread and stopped responding to standard hormone therapy, and who have had limited prior treatments.
Los Angeles, CaliforniaAges 18 years+ - NCT03678025RecruitingPhase 3
Standard treatment for metastatic prostate cancer, with or without local treatment
This Phase 3 trial studies whether using the usual medicines for metastatic prostate cancer, plus a definitive local treatment to the prostate, improves outcomes. It may help determine if treating the prostate directly can benefit people whose cancer has not worsened after initial hormone-based treatment.
Marysville, CaliforniaAges 18 years+ - NCT06654037RecruitingPhase 1
Testing abemaciclib plus 5-FU for advanced colorectal cancer
This trial is testing whether adding a targeted drug called abemaciclib to the standard chemotherapy 5-FU can help people with a specific type of advanced colorectal cancer (MSS) that has stopped responding to other treatments. The goal is to see if this combination is safe and effective.
Irvine, CaliforniaAges 18 years+ - NCT04510597RecruitingPhase 3
Immunotherapy plus surgery versus immunotherapy alone for kidney cancer
This study tests whether adding surgery to remove the kidney improves outcomes compared with continuing immunotherapy without surgery. It is for people with metastatic kidney cancer whose disease has not worsened after initial immunotherapy.
Los Angeles, CaliforniaAges 18 years+ - NCT07300241RecruitingPhase 1
Study of NEO-811 for advanced kidney cancer
This trial tests a new drug called NEO-811 for people with advanced clear cell kidney cancer that has spread and can't be removed with surgery. The goal is to see if it helps when other treatments have stopped working or aren't an option.
Duarte, CaliforniaAges 18 years+ - NCT05372640RecruitingPhase 1
Drug combo trial for rare cancers with shared NUT features
This Phase 1 trial tests the safety and early signs of effectiveness of combining two anti-cancer drugs (ZEN003694 and abemaciclib) in teens and adults with metastatic or unresectable NUT carcinoma, breast cancer, and other solid tumors. It may help by finding a safer dose and whether the drug combination can shrink or control tumors that do not respond to standard treatments.
Los Angeles, CaliforniaAges 12 years+ - NCT07038343RecruitingPhase 1/Phase 2
Testing a new drug for advanced solid tumors
This trial tests a new drug called AVZO-1418, either alone or with other treatments, for people with advanced solid tumors that have spread or cannot be removed. The goal is to see if the drug is safe and effective against certain types of cancer.
Los Angeles, CaliforniaAges 18–75 - NCT06029270RecruitingPhase 2
Adding relatlimab to standard immunotherapy for nasopharyngeal cancer
This trial tests whether adding a new drug called relatlimab to the usual immunotherapy (nivolumab) helps people with nasopharyngeal cancer that has returned or spread. You will get standard chemotherapy plus nivolumab first, then if it works, you may be randomly assigned to get nivolumab alone or with relatlimab.
Dublin, CaliforniaAges 18 years+ - NCT07512271Recruiting
AI Education Tool for Breast Cancer Patients
This study tests a new computer-based education module created by artificial intelligence to help breast cancer patients understand their diagnosis and treatment options. The goal is to see if this tool helps patients feel more informed and prepared for their care.

Glufosfamide vs 5-FU for metastatic pancreatic cancer after gemcitabine
This study compares two chemotherapy drugs—glufosfamide and 5-FU—in people with pancreatic cancer that has spread and got worse after gemcitabine. It aims to see which option works better as a “second-line” treatment.
Whittier, CaliforniaAges 18 years+ - NCT04665947RecruitingEarly Phase 1
Imaging and targeted drug for pancreatic cancer using special radiation
This early study tests a two-step approach: a special PET/CT scan to find pancreatic cancer, followed by a targeted radiation medicine to attack it. It may help researchers learn whether this targeted approach is safe and able to reach pancreatic tumors after standard treatment.
Sacramento, CaliforniaAges 18 years+ - NCT06792695RecruitingPhase 2
Study of new treatments for colorectal cancer
This trial tests new treatment combinations for colorectal cancer that has spread (metastatic). It is for people whose cancer is mismatch repair proficient (pMMR) or microsatellite stable (MSS) and who have not had previous treatment for metastatic disease.
Los Angeles, CaliforniaAges 18–130 - NCT06500455RecruitingPhase 3
Standard vs longer radiation for brain metastases
This trial compares the usual short course of radiation therapy (one session) to a longer course (up to 5 sessions) for people with cancer that has spread to the brain. The goal is to see if the longer course works better and causes fewer side effects.
Anaheim, CaliforniaAges 18 years+ - NCT06217822RecruitingPhase 1
Testing a new radiation therapy for advanced prostate cancer

What taking part in a metastatic 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.
