Recruiting studies in California
- NCT07659795RecruitingPhase 2
Study of VS-7375 for KRAS G12D colorectal cancer
This trial tests a new targeted pill, VS-7375, for people with a specific type of advanced colorectal cancer called KRAS G12D. It's for those who either haven't had treatment yet or whose cancer has worsened after prior therapy.
Los Angeles, CaliforniaAges 18 years+ - NCT07525206RecruitingPhase 3
Combination treatment for advanced colorectal cancer
This trial tests a new drug combination for colorectal cancer that has not responded to other treatments. It compares the new drug with a standard treatment to see which is more effective.
Duarte, CaliforniaAges 18 years+ - NCT07447050RecruitingPhase 2
Riluzole to Prevent Chemo-Related Cognitive Problems
This pilot study tests whether the drug riluzole can help prevent the thinking and memory problems (often called 'chemobrain') that some people experience during chemotherapy. If you are about to start a chemo regimen containing an anthracycline or platinum drug, you may be able to join.
Orange, CaliforniaAges 18 years+ - NCT07446322RecruitingPhase 2
Study of a new drug plus standard chemo for advanced colorectal cancer
This trial tests if adding the experimental drug pelareorep to standard chemotherapy (FOLFIRI) and bevacizumab can help people with a specific type of advanced colorectal cancer that has a RAS mutation and is not caused by high microsatellite instability. You may be able to join if you've already tried one type of chemotherapy and it stopped working or you couldn't tolerate it.
Beverly Hills, CaliforniaAges 18 years+ - NCT07318805RecruitingPhase 1
A study of PF-08032562 for advanced solid tumors
This study tests a new medicine, PF-08032562, for people with advanced breast or colorectal cancer that has not responded to prior treatments. It aims to see if the drug is safe and can help shrink or slow the cancer.
Duarte, CaliforniaAges 18 years+ - NCT07321106RecruitingPhase 1
CBI-1214 for advanced colorectal cancer

Duarte, CaliforniaAges 18 years+ - NCT07226115Recruiting
Predicting chemotherapy outcomes for colorectal cancer
This trial uses a special test on your tumor tissue to see if it can predict how well chemotherapy will work for you. If you have had chemotherapy for stage II or III colorectal cancer after surgery, your stored tumor sample may help develop a tool that could guide future treatment decisions.
Duarte, CaliforniaAges 18–80 - NCT07224724Recruiting
Exosome liquid biopsy for colorectal cancer spread
This study uses a blood test to detect if colorectal cancer that has spread to the liver has also spread to other parts of the body. It may help doctors better understand how the cancer is moving and guide treatment decisions.
Duarte, CaliforniaAges 18 years+ - NCT07227168RecruitingPhase 1
Study of STRO-004 for advanced solid tumors
This trial tests a new drug called STRO-004 for people with advanced solid tumors (cancers that have spread or come back). It aims to see if the drug is safe and effective for those who have already tried other treatments.
San Diego, CaliforniaAges 18 years+ - NCT07143487Recruiting
Family communication after genetic testing for colon cancer
This trial studies how patients with newly diagnosed colon cancer share genetic test results with their family members. It aims to improve communication and support after learning about hereditary risk.
Arroyo Grande, CaliforniaAges 18 years+ - NCT07125729Recruiting
Early cancer detection test for colorectal cancer
This trial uses two blood tests (Signatera and Haystack) to look for tiny bits of cancer DNA after surgery, to find out if the cancer comes back as early as possible. People with stage II, III, or IV colorectal cancer who have had or will have surgery to remove their tumor may join.

A website to improve follow-up care for colorectal cancer survivors
This study tests if an educational website, viewed with a supporter, can improve follow-up care for people who had surgery for stage II or III colorectal cancer. It aims to help patients and their supporters find helpful information together.
Merced, CaliforniaAges 18 years+ - NCT06974110RecruitingPhase 1
Study of a new drug for advanced solid tumors with MSI-H or dMMR
This trial tests an oral medication called MOMA-341 in people with advanced solid tumors that have high microsatellite instability (MSI-H) or mismatch repair deficiency (dMMR). It aims to see if the drug can help when prior immunotherapy hasn't worked or isn't available.
San Diego, CaliforniaAges 18 years+ - NCT06948448RecruitingPhase 2
New treatment for advanced colorectal cancer with PD-L1 biomarker
This trial tests a new drug (ONO-4578) combined with standard chemotherapy and immunotherapy for people with advanced colorectal cancer that has not been treated before and has a specific marker called PD-L1. The goal is to see if this combination works better than the usual treatment.

BBO-11818 for KRAS-mutated cancers
This trial tests a new oral drug (BBO-11818) for people with solid tumors that have a specific KRAS mutation. It's for those whose cancer has spread or cannot be removed by surgery and who have not had other cancers recently.
Sacramento, CaliforniaAges 18 years+ - NCT06710756RecruitingPhase 1/Phase 2
Lead-212 therapy for solid tumors
This trial tests a new radioactive drug, Lead-212 PSV359, for people with advanced solid tumors that have not responded to standard treatments. The drug is designed to find and attack cancer cells.
Los Angeles, CaliforniaAges 18–90 - NCT06625775RecruitingPhase 1
Study of BBO-10203 for advanced solid tumors

Duarte, CaliforniaAges 18 years+ - NCT06580002RecruitingPhase 2
Can Riluzole Help with Chemo Brain? A Pilot Study

Orange, CaliforniaAges 18 years+ - NCT06562192RecruitingPhase 1
Testing a radioactive drug for advanced pancreatic, lung, breast, and colorectal cancers

It is specifically looking for participants who identify as Black or African American and/or Hispanic or Latino to help understand how the drug works in these groups.
Whittier, CaliforniaAges 18 years+ - NCT06440005RecruitingPhase 1
Testing AGX101 for advanced solid tumors

Los Angeles, CaliforniaAges 18 years+ - NCT06342440Recruiting
Early detection of colon cancer and advanced polyps
This study aims to find colorectal cancer and advanced polyps (adenomas) earlier by looking at blood samples. Researchers hope a simple blood test might one day help detect colon cancer before it spreads.

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.
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.
