Recruiting studies in California
- NCT06995898Recruiting
Blood test study for early cancer detection
This study is testing a new blood test that may help find cancer early. You will give blood samples over a year, and researchers will check them for signs of cancer.
Pleasanton, CaliforniaAges 45–75 - NCT06751329RecruitingPhase 1/Phase 2
Study of DM002 for advanced solid tumors
This trial tests a new drug called DM002 for people with advanced solid tumors that have not responded to standard treatments. The drug targets two proteins (MUC1 and HER3) found on some cancer cells, and may help shrink tumors or slow their growth.
San Francisco, CaliforniaAges 18 years+ - NCT06418204Recruiting
Cannabis use among cancer patients in community clinics
This study looks at how cancer patients use cannabis (marijuana) and cannabis products to manage symptoms during chemotherapy or immunotherapy. The goal is to learn about the benefits and risks so doctors can better guide patients.
Antioch, CaliforniaAges 18 years+ - NCT06376565Recruiting
Improving colonoscopy follow-up for high-risk polyps
This study aims to understand why some people return for a follow-up colonoscopy after having high-risk colon polyps and to find ways to improve the process. It involves interviews and testing new approaches to ensure patients get the right follow-up care.
Los Angeles, CaliforniaAges 21 years+ - NCT04291755Enrolling by invitation
Stool bank for people receiving cancer immunotherapy
This study is building a “stool bank,” meaning they collect and store stool samples from people who are getting cancer immunotherapy. Researchers plan to analyze these samples to better understand cancer and treatment—your participation may help future research.
Fountain Valley, CaliforniaAges 18 years+ - NCT05107674RecruitingPhase 1
Early drug study for advanced cancers that have limited options
This Phase 1 study tests NX-1607 in adults with advanced cancers that are hard to treat with standard care. It focuses on safety and early signs of how well the drug may work in specific cancer types.
Duarte, CaliforniaAges 18 years+ - NCT06568016Recruiting
Helping patients get colonoscopy after abnormal stool test
This study tests a new clinic program to help patients complete a colonoscopy if they received an abnormal result from a fecal immunochemical test (FIT), a simple stool test for colon cancer. It focuses on community health centers and aims to make follow-up care easier.

What taking part in a colorectal 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 colorectal cancer clinical trials in California?
- Yes. We're currently tracking 151 recruiting colorectal 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 colorectal 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 colorectal 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.
Not the right time?
New colorectal cancer 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.
