Recruiting studies in California
- NCT02328677Recruiting
Colorectal cancer study for newly diagnosed patients
This study enrolls people newly diagnosed with colon or rectal cancer to learn about their care and outcomes. You might be able to join if you meet the age, language, and consent requirements.
Los Angeles, CaliforniaAges 18–89 - 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+ - 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.
San Francisco, CaliforniaAges 18 years+ - NCT06937177RecruitingPhase 2
Testing mifomelatide to help maintain weight during chemo
This trial tests an investigational drug called mifomelatide (TCMCB07) to see if it can help people with newly diagnosed colorectal or pancreatic cancer maintain a healthy weight while receiving certain types of chemotherapy. You would give yourself a daily injection under the skin.
Los Angeles, 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.
Los Angeles, CaliforniaAges 18 years+ - NCT07458347RecruitingPhase 1
A new oral drug for KRAS-mutated advanced cancer
This trial tests a new oral drug, KST-6051, for people with advanced solid tumors (like lung, pancreatic, colon, or other cancers) that have a specific KRAS gene mutation. The goal is to find the best dose and see if it's safe.
Los Angeles, CaliforniaAges 18 years+ - NCT04792684Recruiting
Collecting colon samples from adults with colon findings
This study collects body samples to help evaluate tests for people with suspected or newly diagnosed colorectal conditions, often around the time of colonoscopy or surgery. Depending on the arm, you may be asked to have a colonoscopy soon or to provide samples before planned surgery.
Chula Vista, CaliforniaAges 45–84 - NCT07224841Recruiting
Blood test to predict targeted therapy response in colorectal cancer
This study is developing a blood test that looks at DNA signals to see if certain targeted therapies will work for people with metastatic colorectal cancer. It may help doctors choose the right treatment in the future.
Duarte, CaliforniaAges 18 years+ - NCT05803382RecruitingPhase 1
Adding a new drug to capecitabine for metastatic colorectal cancer
This Phase 1 study tests a new anti-cancer drug (ZEN003694) added to the usual chemotherapy capecitabine. It is for adults with colorectal cancer (and possibly other cancers) that has spread or cannot be removed and has continued despite prior standard treatment.
Irvine, CaliforniaAges 18 years+ - NCT07221357RecruitingPhase 2/Phase 3
Pumitamig plus chemo vs standard care for new colorectal cancer
This trial tests a new drug called Pumitamig combined with chemotherapy against standard bevacizumab plus chemotherapy for people with advanced colorectal cancer that cannot be surgically removed and hasn't been treated yet. The goal is to see which combination works better and is safer.
Los Angeles, CaliforniaAges 18 years+ - NCT05929820Recruiting
Test a program to improve colon cancer screening
This study tests whether Protect Your Colon™ helps people stay up to date with colon cancer (CRC) screening. It may help you get reminders and guidance so screening happens when it should.
Los Angeles, CaliforniaAges 45–75 - NCT05234177Recruiting
Blood test to track colorectal cancer after surgery
This study looks at a blood “DNA” test to see if it can help monitor colorectal cancer after surgery. It may benefit you by improving how doctors track cancer during routine follow-up visits.
Fountain Valley, CaliforniaAges 18 years+ - NCT05005403RecruitingPhase 1
Testing azirkitug for lung, head/neck, and other solid cancers
This Phase 1 study tests how a new medicine (azirkitug) behaves in the body and how safe it is, given by IV infusion alone or with other cancer drugs. It may help people with several advanced solid tumor cancers, especially after standard treatments have stopped working.
Duarte, CaliforniaAges 18 years+ - NCT06662786RecruitingPhase 3
Amivantamab plus chemo vs. standard chemo for left-sided colorectal cancer
This trial compares a new combination (amivantamab plus chemotherapy) with the standard treatment (cetuximab plus chemotherapy) as the first therapy for people with left-sided colorectal cancer that has spread. The goal is to see which approach works better when the tumor has no mutations in the KRAS, NRAS, or BRAF genes.
Bakersfield, CaliforniaAges 18 years+ - NCT05253651RecruitingPhase 3
Tucatinib plus trastuzumab with chemo for HER2+ metastatic colon cancer
This trial tests whether adding tucatinib and trastuzumab to standard chemotherapy works better than standard treatment alone for people with HER2-positive metastatic colon or rectal cancer. It aims to improve how long people live and how well tumors respond as first treatment for advanced disease.
Anaheim, CaliforniaAges 18 years+ - NCT07224750Recruiting
A blood test to find early signs of gastrointestinal cancer
This study is testing a blood-based test to detect unique molecules (called miRNAs) that may signal the presence of several types of gut or digestive system cancers. The goal is to develop a simple screening tool that could catch these cancers earlier.
Duarte, CaliforniaAges 18 years+ - NCT07094204RecruitingPhase 1
A study of ASP5834 for adults with solid tumors and KRAS mutations
This trial is testing a new drug called ASP5834 for people with advanced solid tumors that have a specific change in the KRAS gene. The study will find the best dose and see if it helps shrink tumors.
Santa Monica, CaliforniaAges 18 years+ - NCT06542835Recruiting

What taking part in a colorectal cancer (crc) 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.
