Recruiting studies in California
- NCT06399419RecruitingPhase 1

Fullerton, CaliforniaAges 18 years+ - NCT07664397RecruitingPhase 1
Imaging study of a new tracer for cancer detection
This study tests a new imaging tracer called [89Zr]DFO-YS5 that may help detect certain cancers on a PET-CT scan. The goal is to see if this tracer is safe and works well for finding tumors, which could one day help doctors plan better treatments.
San Francisco, CaliforniaAges 18 years+ - NCT07590934RecruitingPhase 1/Phase 2

Duarte, CaliforniaAges 18–99 - NCT07581080Recruiting
Biofield therapy to ease fatigue from cancer immunotherapy
This study tests whether Reiki—a hands-on healing practice—can help reduce severe tiredness in cancer patients receiving immunotherapy drugs. If it works, it could offer patients another way to manage fatigue alongside their cancer treatment.
Irvine, CaliforniaAges 18 years+ - NCT07564141RecruitingPhase 3
New Drug for Recurrent Ovarian Cancer After Chemotherapy
This study tests a new medicine called Rina-S (with or without a blood vessel-blocking drug) compared to standard chemotherapy options for ovarian cancer that has come back after initial treatment. The goal is to see if Rina-S works better and is safer than current standard care.
Duarte, CaliforniaAges 18 years+ - NCT06281678RecruitingPhase 2
Study of IBI363 for advanced solid tumors
This trial tests a new drug called IBI363 for people with advanced solid tumors. It aims to see if the drug is safe and effective. You may be able to join if you are generally well and have not had other cancer treatments recently.
San Francisco, CaliforniaAges 18 years+ - NCT05877430RecruitingPhase 1/Phase 2
Testing an anti-cancer drug plus pembrolizumab for advanced cancers
This Phase 1/2 study tests the safety and early signs of benefit from CJRB-101 when combined with pembrolizumab (Keytruda) in people with advanced or metastatic lung, head and neck, or melanoma cancer. It may help some participants, but the main goal is to see how safe the combination is and whether it can control cancer.
Irvine, CaliforniaAges 18 years+ - NCT07541079RecruitingPhase 3
Testing a New Breast Cancer Drug for Women Who Can't Tolerate Current Therapy
This study tests giredestrant, a new hormone-blocking medication, in postmenopausal women with early-stage ER+ breast cancer who have experienced intolerable side effects from their current aromatase inhibitor therapy. The trial will measure how well you tolerate this new drug and how it affects your quality of life.
Fountain Valley, CaliforniaAges 18 years+ - NCT07524218Recruiting
Meal Timing During Cancer Treatment Recovery
This study looks at how the timing of meals during cancer treatment recovery affects how well you tolerate and respond to your therapy. Researchers want to learn whether eating during certain hours of the day might help your body handle chemotherapy, targeted drugs, or immunotherapy better.
Los Angeles, CaliforniaAges 18 years+ - NCT07499674RecruitingPhase 3
A lung cancer surgery study to test a special imaging dye
This trial tests a dye called abenacianine (VGT-309) that may help surgeons see cancer more clearly during lung surgery. It looks at whether the dye is safe and effective for identifying cancer in people having surgery to remove a lung lesion or mass.
Duarte, CaliforniaAges 18 years+ - NCT07487844Recruiting
Electric field therapy for breast cancer that has spread
This trial tests a new way to treat breast cancer that has spread to the skin or just under the skin. It uses short electric pulses to target tumors without cutting. The goal is to see if this approach can safely destroy cancer cells in those spots.

What taking part in a 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 cancer clinical trials in California?
- Yes. We're currently tracking 1,320 recruiting 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 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 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 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.
