Recruiting studies in California
- NCT06774027Recruiting

Testing a biosimilar ipilimumab for advanced liver cancer
This trial tests a new version of the immunotherapy drug ipilimumab (called HLX13) against the approved version (YERVOY) for people with advanced liver cancer that cannot be removed by surgery. The goal is to see if the new version works similarly and is as safe.
Glendale, CaliforniaAges 18–65 - NCT07216105RecruitingPhase 1
FT836 immune cell therapy for advanced solid tumors
This study tests a new immune cell therapy called FT836, given alone or with chemotherapy or other antibodies, for people with advanced solid tumors that have not responded to previous treatments. The goal is to see if it is safe and helps shrink or control tumors.

Memory-sparing radiation for brain metastases in small cell lung cancer
This study tests whether focusing high-dose radiation only on brain tumor spots, while avoiding the hippocampus (a brain area important for memory), helps protect memory and thinking compared with standard whole-brain radiation. It’s for people with small cell lung cancer that has spread to the brain.
Anaheim, CaliforniaAges 18 years+ - NCT00477100Recruiting
Breast cancer tissue and data registry for research

What taking part in a carcinoma 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.
Carcinoma trials in other states
Common questions
- Are there carcinoma clinical trials in California?
- Yes. We're currently tracking 462 recruiting carcinoma 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 carcinoma 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 carcinoma 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 carcinoma 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.
Clin2 helps you find and understand clinical trials and does not provide medical advice. Study data comes from ClinicalTrials.gov. Talk with your doctor about whether a specific trial is right for you.
