Recruiting studies in California
- NCT07222800RecruitingPhase 3
Testing a new drug plus chemo for stage 4 colorectal cancer

Berkeley, CaliforniaAges 18 years+ - NCT04924075RecruitingPhase 2
Belzutifan for cancers linked to VHL or HIF-2α changes
This Phase 2 study tests belzutifan (MK-6482) to treat certain advanced cancers caused by specific gene or disease changes, including VHL-related tumors and HIF-2α related tumors. It may help shrink tumors or slow their growth in people whose cancer matches these genetic or disease patterns.
Los Angeles, CaliforniaAges 12 years+ - NCT06215222Recruiting
Studying gut bacteria in IBS and digestive issues
This study uses a tiny capsule to collect samples from your small intestine to learn about gut bacteria in people with IBS or other functional gut disorders. It could help researchers understand what causes digestive symptoms.
Redwood City, CaliforniaAges 18–70 - NCT01492231Enrolling by invitation
Study outcomes from endoscopy procedures at a digestive center
This trial collects information about how interventional endoscopy procedures affect patients and outcomes after the procedure. You may be able to join if you’re an adult and scheduled for an endoscopy procedure at the specified digestive disease center.
Orange, CaliforniaAges 18 years+ - NCT05978141Recruiting

What taking part in a gastrointestinal diseases 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 gastrointestinal diseases clinical trials in California?
- Yes. We're currently tracking 5 recruiting gastrointestinal diseases 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 gastrointestinal diseases 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 gastrointestinal diseases 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 gastrointestinal diseases 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.
