Recruiting studies in California
- NCT06533826RecruitingPhase 2
Testing two antibody drugs for HER2-low breast cancer
This trial tests two antibody-drug conjugates (Enhertu and Datroway) for breast cancer that is HER2-low or HER2-0. It aims to find the best treatment sequence for people whose cancer has stopped responding to prior therapy.
San Francisco, CaliforniaAges 18 years+ - NCT07007559RecruitingPhase 2
Evorpacept with trastuzumab and chemo for HER2-positive breast cancer

Orange, CaliforniaAges 18 years+ - NCT05519449RecruitingPhase 1
Testing a PSMA-targeting treatment for advanced prostate cancer
This Phase 1 trial tests JANX007 in men with metastatic castration-resistant prostate cancer (cancer that keeps growing despite standard hormone treatment). It aims to find a safe dose and see whether the treatment can shrink tumors or slow progression.
Los Angeles, CaliforniaAges 18–100 - 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+ - NCT06252649RecruitingPhase 3
Study of new drug combo for KRAS G12C colorectal cancer
This trial tests a new combination of drugs (sotorasib, panitumumab, and FOLFIRI) against the standard treatment for colorectal cancer that has spread. It's for people whose tumor has a specific KRAS G12C mutation and who have not had chemotherapy before for advanced disease.
Los Angeles, CaliforniaAges 18 years+ - NCT06336902RecruitingPhase 1
Immunotherapy plus fasting diet and vitamin C for KRAS-mutated colorectal cancer
This trial tests a combination of two immunotherapy drugs (botensilimab and balstilimab) plus a fasting-mimicking diet and high-dose vitamin C for people with a specific type of advanced colorectal cancer (KRAS-mutated). It aims to see if this approach can help when standard treatments have stopped working.
Fullerton, CaliforniaAges 18 years+ - NCT05455619RecruitingPhase 1/Phase 2
Targeted drugs for PI3K-altered, HR+/HER2- breast cancer
This Phase 1/2 trial tests how well a combination of targeted medicines works for advanced or returning HR+/HER2- breast cancer that has a PI3K pathway change (such as PIK3CA, PTEN, or AKT1). It may help by blocking growth signals in the cancer and is especially for people whose cancer has progressed after hormone therapy and a CDK4/6 inhibitor.
Loma Linda, CaliforniaAges 18 years+ - NCT07193511RecruitingPhase 1/Phase 2
A new drug for advanced bladder and other solid tumors
This trial tests a new drug, AVZO-103, alone or with other treatments, for people with advanced bladder cancer or certain other solid tumors. It aims to find out if the drug is safe and effective.
San Francisco, CaliforniaAges 18 years+ - NCT05766371RecruitingPhase 2
Immunotherapy plus targeted radiation for advanced prostate cancer
This study combines two treatments: pembrolizumab, which helps your immune system fight cancer, and a targeted radioactive medicine (177Lu-PSMA-617) that seeks out and damages prostate cancer cells. It may help men whose prostate cancer has spread despite initial hormone therapy.
San Francisco, CaliforniaAges 18 years+ - NCT07817147Recruiting
Microwave ablation treatment for advanced cancer
This study tests a procedure called microwave ablation (using heat to destroy cancer cells) for tumors that are hard to remove with surgery. It aims to see if the procedure is safe and effective when done through a scope in the stomach.
Los Angeles, CaliforniaAges 18 years+ - NCT07392892RecruitingPhase 2/Phase 3
Study of PF-08634404 plus chemo for stomach and esophagus cancer
This trial tests a new study drug called PF-08634404 in combination with standard chemotherapy for people with stomach, gastroesophageal junction, or esophagus cancer that has spread. It aims to see if adding this drug helps the treatment work better.
Atascadero, CaliforniaAges 18 years+ - NCT05254171RecruitingPhase 2/Phase 3
Trial adds SBP-101 to standard chemo for pancreatic cancer
This trial studies whether adding SBP-101 to standard chemotherapy (gemcitabine plus nab-paclitaxel) can improve outcomes in people with metastatic pancreatic cancer. You may be eligible if you have not yet started treatment for metastatic disease and meet other health and test requirements.
Fullerton, 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+ - NCT06861088RecruitingPhase 3
Kinisoquin for preventing blood clots in pancreatic cancer
This trial tests whether an investigational drug called Kinisoquin™ can help prevent blood clots in people with advanced pancreatic cancer who are starting their first chemotherapy. It may be a good option if you are looking for extra protection against clots during treatment.
Ventura, 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+ - NCT06228053RecruitingPhase 2
Study of SX-682 plus enzalutamide for men with advanced prostate cancer
This trial tests whether adding the drug SX-682 to enzalutamide can help men whose prostate cancer has stopped responding to other hormone treatments. You may be eligible if your cancer is growing despite treatment with abiraterone, darolutamide, apalutamide, or enzalutamide.
Los Angeles, CaliforniaAges 18 years+ - NCT07111507RecruitingPhase 2
Tarlatamab for advanced prostate cancer

Santa Rosa, CaliforniaAges 18 years+ - NCT06228326RecruitingPhase 1/Phase 2
Study of KB707 for advanced cancers affecting the lungs
This trial tests a new medicine called KB707 for people with advanced cancers that affect the lungs. It uses a virus to deliver a gene that may help your immune system fight the tumor. The study is especially looking at people with lung cancer (NSCLC) or other solid tumors that have spread to the lungs and haven't responded to standard treatments.
Beverly Hills, CaliforniaAges 18 years+ - NCT06879041RecruitingPhase 1
Study of a radioactive drug 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.

Common questions
- Are there metastatic cancer clinical trials in California?
- Yes. We're currently tracking 373 recruiting metastatic cancer studies with a site in California, each rewritten in plain language so you can see what it's testing and who it's for.
- How do I find out if I qualify for a metastatic cancer study in California?
- Each study lists its eligibility rules — age, diagnosis, prior treatments. On every trial page we explain these in plain language and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Do I have to live in California to take part?
- Not necessarily. These studies have a site in California, but eligibility is about your health, not your address — some people travel to take part, and a few studies reimburse travel. The study team can tell you what's required.
- Does it cost anything to join a metastatic cancer trial?
- Using Clin2 is always free. Many trials cover the study treatment and related visits; some reimburse travel. The study team explains exactly what's covered before you decide.
Not the right time?
New metastatic cancer studies open in California regularly. Set up a health profile and we’ll quietly watch for studies that fit you and email you when one opens.
