Duarte, CaliforniaAges 2 months+ - NCT07628634RecruitingEarly Phase 1
Testing a Low-Methionine Diet in Solid Tumor Patients
This early-stage study explores whether eating a diet low in methionine (a natural amino acid found in protein) might help people with advanced solid tumors. Researchers will track how this dietary change affects blood levels and may improve treatment outcomes alongside standard cancer care.
Orange, CaliforniaAges 18 years+ - NCT06772623RecruitingPhase 1/Phase 2
Study of telisotuzumab adizutecan plus immunotherapy for advanced lung cancer
This trial tests a new combination treatment for people with advanced non-squamous non-small cell lung cancer who haven't received prior therapy for advanced disease and don't have specific gene changes. The treatment includes an antibody-drug conjugate (telisotuzumab adizutecan) plus an immunotherapy drug (PD-1 checkpoint inhibitor) to see if it helps shrink tumors and improve outcomes.

What taking part in a advanced or metastatic solid tumors 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 advanced or metastatic solid tumors clinical trials in California?
- Yes. We're currently tracking 702 recruiting advanced or metastatic solid tumors 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 advanced or metastatic solid tumors study in California?

- 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 advanced or metastatic solid tumors 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.
