Fruquintinib for advanced colorectal cancer in minority populations
This trial tests a medication called fruquintinib (an oral pill) for people with advanced colorectal cancer that has not responded to prior treatments. 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+ - NCT06625775RecruitingPhase 1
Study of BBO-10203 for advanced solid tumors
This trial tests a new drug called BBO-10203, alone or combined with other cancer treatments, for people with certain advanced breast, colorectal, or lung cancers. It aims to see if the drug is safe and effective.
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.
San Diego, CaliforniaAges 18 years+ - NCT06342401Recruiting
Early onset colorectal cancer detection study
This study aims to improve detection of colorectal cancer in people diagnosed before age 50. It compares samples from patients with cancer to those without to find new early detection methods.
Duarte, CaliforniaAges 18–50 - NCT06314958Recruiting
Follow-up after colorectal cancer treatment
This study follows people who have finished treatment for stage II (high-risk) or stage III colorectal cancer and are now cancer-free. Researchers want to learn more about which factors might predict if the cancer will come back, so they can better personalize follow-up care.
Monrovia, CaliforniaAges 18 years+ - 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+ - 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 - NCT06917079RecruitingPhase 1
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.
San Francisco, CaliforniaAges 18 years+ - NCT07018869RecruitingPhase 3
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+ - NCT07033026RecruitingPhase 2
Study of NGM120 for weight loss in colorectal cancer
This study tests an experimental drug called NGM120 for people with colorectal cancer who are losing weight (a condition called cancer cachexia). It is a placebo-controlled trial, meaning some participants will receive the drug and some will receive a placebo, to see if the drug helps stop or reverse this weight loss.
Los Angeles, 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+ - NCT06191185Enrolling by invitation
Improving colonoscopy follow-up after abnormal FIT
This trial tests a program to help people who had an abnormal FIT stool test follow through with getting a colonoscopy. The goal is to improve cancer screening by providing extra support through a care team and technology.
San Francisco, CaliforniaAges 18 years+ - NCT07284849RecruitingPhase 3
Testing a new drug combo for advanced colorectal cancer
This trial tests whether adding an experimental drug (INCA33890) to standard chemotherapy and bevacizumab helps people with a certain type of advanced colorectal cancer. It is for those whose cancer has spread and has not been treated yet with systemic therapy.
Fountain Valley, CaliforniaAges 18 years+ - NCT07228832RecruitingPhase 3
Study of two drugs with chemo for advanced colorectal cancer
This clinical trial tests a new drug, ivonescimab, against an approved drug, bevacizumab. Both are given with standard chemotherapy (FOLFOX) for people with advanced colorectal cancer that has not been treated yet with chemo or other drugs.
Beverly Hills, CaliforniaAges 18 years+ - NCT06820463RecruitingPhase 2
Study of telisotuzumab adizutecan plus chemo for metastatic colorectal cancer
This trial tests a new drug combination for people with metastatic colorectal cancer. The study includes an experimental antibody-drug conjugate (telisotuzumab adizutecan) plus standard chemotherapy and targeted therapies, to see if it works better than current options.
Duarte, CaliforniaAges 18 years+ - NCT06792695RecruitingPhase 2
Study of new treatments for colorectal cancer
This trial tests new treatment combinations for colorectal cancer that has spread (metastatic). It is for people whose cancer is mismatch repair proficient (pMMR) or microsatellite stable (MSS) and who have not had previous treatment for metastatic disease.
Los Angeles, CaliforniaAges 18–130 - NCT06298916RecruitingPhase 1/Phase 2
Study of 64Cu-LNTH-1363S in Sarcoma or GI Cancer
This trial tests a new imaging agent, 64Cu-LNTH-1363S, to see if it can find certain sarcomas and gastrointestinal cancers. The goal is to help doctors better see where your cancer is and plan the best treatment. You may be eligible if you have a sarcoma or a GI cancer and are willing to have a tumor tissue sample taken.
Orange, CaliforniaAges 15 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+ - 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+ - NCT07224815Recruiting
DNA markers to predict chemo response in advanced colon cancer
This study uses a blood test to look for specific DNA changes that may help predict how well chemotherapy works in people with metastatic colorectal cancer. The goal is to find markers that could guide future treatment decisions.
Duarte, 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+ - NCT02328677Recruiting
Colorectal cancer study for newly diagnosed patients

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.
