It may help your immune system recognize your specific tumor features.
Orange, CaliforniaAges 18 years+ - NCT07744126RecruitingPhase 2
Combination drug therapy for head and neck cancer that has spread
This trial tests a new combination of two drugs (telisotuzumab adizutecan and pembrolizumab) for people with head and neck cancer that has come back or spread and cannot be cured with local treatments. The goal is to see if this combination can help control the cancer and to find the best dose.
Duarte, CaliforniaAges 18 years+ - NCT07697456RecruitingPhase 2
Study of advanced therapies for Crohn's or ulcerative colitis
This study tests advanced treatments for people with moderate to severe Crohn's disease or ulcerative colitis who haven't responded to at least one previous therapy. It aims to find better options for managing these conditions.

This trial tests the combination of pembrolizumab (Keytruda) with or without a new drug, sacituzumab tirumotecan (Sac-TMT), as initial treatment for advanced squamous non-small cell lung cancer. It aims to see if adding Sac-TMT after initial treatment helps keep cancer under control longer.
Burbank, CaliforniaAges 18 years+ - NCT07661563Recruiting
Alcohol support via text and chat in the emergency department
This study tests whether a friendly computer chat program, combined with text message reminders, can help reduce risky drinking in people who visit the emergency department. It aims to see if this approach is easier to use and helps you cut back on alcohol.
Palo Alto, CaliforniaAges 18–65 - NCT07643896Recruiting
Blood test for pregnancy risk assessment using fetal cells
This study tests a new blood test that looks for fetal cells in your bloodstream to check your baby's health during pregnancy. The test is non-invasive—just a regular blood draw—and aims to help identify pregnancy risks earlier than traditional methods.
Riverside, CaliforniaAges Any age - NCT04684602RecruitingPhase 1/Phase 2
Study of stem cells for several short- and long-term illnesses
This early-stage study tests whether injections of mesenchymal stem cells can be safe and helpful for certain chronic (long-term) and acute (short-term) conditions. You might be considered if you can consent, are able to return for follow-up visits, and do not have key reasons that would make stem-cell treatment unsafe.

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 701 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.
