Recruiting studies in California
- NCT06654037RecruitingPhase 1
Testing abemaciclib plus 5-FU for advanced colorectal cancer
This trial is testing whether adding a targeted drug called abemaciclib to the standard chemotherapy 5-FU can help people with a specific type of advanced colorectal cancer (MSS) that has stopped responding to other treatments. The goal is to see if this combination is safe and effective.
Irvine, CaliforniaAges 18 years+ - NCT06634875RecruitingPhase 2
Test of isunakinra alone or with pembrolizumab for colorectal cancer
This trial tests a new drug combination (isunakinra plus pembrolizumab) for people with a specific type of colorectal cancer (MSS, RAS-mutated) that has a high tumor mutational burden. It may help if other treatments have stopped working.
Los Angeles, CaliforniaAges 18 years+ - NCT06101277Recruiting
Local therapy for limited new cancer growth in digestive cancers
This trial tests a cancer treatment that uses local therapies (like radiation or targeted heat) to destroy a small number of growing spots. It is for people with certain gastrointestinal cancers whose main treatment is working well except for a few new spots, so they can avoid switching to a different drug right away.
Sacramento, CaliforniaAges 18 years+ - NCT05691491RecruitingPhase 1/Phase 2
Temozolomide plus M1774 for advanced metastatic cancers
This Phase 1/2 trial tests a combination of temozolomide and M1774 to see how safe it is and whether it can help shrink advanced cancers that have spread. It focuses on certain tumor types and specific biomarker results, and it may be an option if standard treatments have been tried or aren’t possible.
Orange, CaliforniaAges 18 years+ - NCT04907643Recruiting
Virtual reality program to reduce stomach-cancer pain
This trial tests whether virtual reality (VR) can improve pain and other day-to-day symptoms in people with certain gastrointestinal cancers. You’d use VR for pain relief while researchers measure how you’re feeling.
Los Angeles, CaliforniaAges 18–99 - NCT07216105RecruitingPhase 1
New immune cell treatment for advanced solid tumors
This trial tests a new treatment using specially engineered immune cells (called FT836) for people with advanced solid tumors that have not responded to other treatments. It may be given alone or with chemotherapy and/or other antibody medicines. The study aims to see if this approach can shrink tumors or slow their growth.
La Jolla, CaliforniaAges 18 years+ - NCT05786924RecruitingPhase 1/Phase 2
Targeted cancer drug study for RAS/RAF mutation-positive tumors
This Phase 1/2 study tests S241656 (a targeted cancer medicine) in people whose cancers have certain “RAS/RAF” gene changes. It may help shrink tumors or control cancer growth, and also finds the safest dose and best way to use the drug.
Los Angeles, CaliforniaAges 18 years+ - NCT04929223RecruitingPhase 1
Targeted drug study for metastatic colon or rectal cancer
This Phase 1 study tests targeted cancer treatments in people with metastatic colorectal cancer, using genetic “biomarker” results to match you to the right treatment group. It focuses first on safety, and also looks for early signs the treatment may work in specific tumor subgroups.
Duarte, CaliforniaAges 18 years+ - NCT07775287RecruitingPhase 3
Petosemtamab plus chemotherapy for advanced colorectal cancer
This study tests a new drug called petosemtamab combined with chemotherapy for people with advanced colorectal cancer that has not responded to one prior treatment. The trial aims to see if adding petosemtamab helps the cancer shrink or grow more slowly compared to adding a standard targeted therapy like cetuximab or bevacizumab.
Los Angeles, CaliforniaAges 18 years+ - NCT07224789Recruiting
Finding colorectal cancer early with a blood test for circular RNA
This study is testing whether a simple blood test can detect circular RNA, a potential early marker for colorectal cancer. If you have early-stage colorectal cancer (stage I–III) and have had a blood sample taken before any treatment, you may be able to help researchers develop a better detection method.
Duarte, CaliforniaAges 18 years+ - NCT05379595RecruitingPhase 1/Phase 2
Amivantamab for advanced colon or rectal cancer with specific tumor traits
This Phase 1/2 study tests amivantamab alone or combined with standard chemotherapy to treat advanced or metastatic colon or rectal cancer. You may be able to join if your tumor has the right genetic profile (typically “wild-type” for certain genes and no HER2 amplification) and your cancer has measurable or biopsy-able lesions.
Los Angeles, CaliforniaAges 18 years+ - NCT06607458RecruitingPhase 2
Liver-focused chemo for metastatic colorectal cancer
This trial tests giving high-dose melphalan directly into the liver's blood supply, followed by standard cancer therapy, for people whose colorectal cancer has spread mainly to the liver. The goal is to see if this approach is safer and works better than standard treatment alone.
Santa Monica, CaliforniaAges 18 years+ - NCT04657068RecruitingPhase 1/Phase 2
Study of ART0380 for advanced solid tumors
This study tests a new drug called ART0380 for people with advanced solid tumors that have not responded to standard treatments. It may be especially helpful for those with certain DNA repair gene changes (like ATM or BRCA). The drug will be given alone or with chemotherapy (gemcitabine or irinotecan) depending on the part of the trial.
Santa Barbara, CaliforniaAges 18 years+ - NCT06225011RecruitingPhase 1
Can a common antidepressant help your immune system fight colorectal cancer before surgery?

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.
