Recruiting studies in California
- NCT05176483RecruitingPhase 1
New drug combinations for advanced solid tumors
This trial tests a new drug called zanzalintinib, which may slow or shrink various types of advanced cancer. It is given together with other cancer treatments, and the study is looking at many different cancers including kidney, prostate, bladder, lung, liver, and more.
Palo Alto, CaliforniaAges 18 years+ - NCT07339176RecruitingPhase 1/Phase 2
A trial of N17350 injected into tumors for advanced solid cancers
This trial tests an experimental drug, N17350, that is injected directly into tumors. It is for people with advanced solid tumors that have stopped responding to standard treatments or who cannot receive them. The study aims to see if this approach is safe and effective.
Los Angeles, CaliforniaAges 18 years+ - NCT06047379RecruitingPhase 1/Phase 2
Testing NEO212 for brain tumors and metastases
This trial tests a new drug called NEO212 for people with certain brain tumors (like astrocytoma or glioblastoma) or cancer that has spread to the brain from other parts of the body. The goal is to see if it is safe and if it can help shrink or control the tumors.
Beverly Hills, CaliforniaAges 18 years+ - NCT05533697RecruitingPhase 1/Phase 2
mRNA medicine with or without immunotherapy for advanced solid cancers
This Phase 1/2 study tests an mRNA vaccine (mRNA-4359) either alone or combined with an immune checkpoint antibody (immunotherapy). It’s for people with advanced solid tumors to see if it can shrink tumors and how safe it is.

CRX100 drug trial for advanced cancers with or without pembrolizumab
This Phase 1 trial tests CRX100 (a new cancer medicine) alone and with pembrolizumab (an immune checkpoint drug) in people with advanced solid tumors. It’s mainly designed to check safety and side effects, and to see whether tumors respond, potentially helping people whose cancer has come back or stopped responding to standard treatment.

What taking part in a solid tumor 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 solid tumor cancer clinical trials in California?
- Yes. We're currently tracking 313 recruiting solid tumor 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 solid tumor 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 solid tumor 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.
