La Jolla, CaliforniaAges 18 years+ - NCT07222800RecruitingPhase 3
Testing a new drug plus chemo for stage 4 colorectal cancer
This study tests a new experimental drug (PF-08634404) combined with standard chemotherapy for people with stage 4 colorectal cancer who have not yet been treated for their advanced disease. The goal is to see if the combination helps shrink or slow the growth of tumors.
Berkeley, 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.
Irvine, 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+ - 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+ - NCT03659448RecruitingPhase 3
Test drug that helps map colon and rectal cancer during surgery
This Phase 3 study tests SGM-101, a drug used during surgery to help doctors better outline primary, recurrent, and spread (metastatic) colorectal cancer. It may improve how completely tumors are identified and removed during an operation.
Duarte, CaliforniaAges 18 years+ - NCT06603519Enrolling by invitation
Can a diet reduce inflammation after a colonoscopy?
This study tests whether a special diet can help reduce inflammation and improve gut health after a colonoscopy. It is for people who are getting a repeat colonoscopy because they've had polyps before.
San Diego, CaliforniaAges 18 years+ - NCT06750094RecruitingPhase 3
Study of amivantamab plus FOLFIRI in colorectal cancer
This trial tests adding amivantamab to standard FOLFIRI chemotherapy for people with certain types of colorectal cancer that have already been treated once. It aims to see if this combination works better than another common treatment (cetuximab or bevacizumab plus FOLFIRI).
Bakersfield, CaliforniaAges 18 years+ - NCT06131840RecruitingPhase 1
Study of SGN-CEACAM5C for advanced solid tumors
This trial tests a new drug called SGN-CEACAM5C in people with advanced solid tumors that have not responded to other treatments. The drug targets a protein on cancer cells to try to stop them from growing.
Duarte, CaliforniaAges 18 years+ - NCT06051695RecruitingPhase 1/Phase 2
CAR T cell therapy for mesothelin-positive solid tumors
This trial tests a new type of immune cell therapy (CAR T-cells) designed to target cancer cells that have a protein called mesothelin but have lost a marker that lets them hide from the immune system. It's for people with advanced solid tumors who have already tried standard treatments.
Los Angeles, CaliforniaAges 18 years+ - NCT04329494RecruitingPhase 1
Study of targeted drug delivery into the abdomen using PIPAC
This Phase 1 trial tests PIPAC, a way to deliver anti-cancer medicine directly into the abdomen using a minimally invasive procedure. It is for people with peritoneal spread from certain cancers to see whether this approach is safe and potentially helpful.
Duarte, CaliforniaAges 18 years+ - NCT00843375Recruiting
Testing stool samples to find early colon cancer and polyps
This study checks stool samples to see how well stool tests can detect early colon cancer and precancerous growths called adenomas. If you qualify, you’ll collect stool samples for a lab test (FIT) and sometimes this helps sort who should get follow-up testing.
Los Angeles, 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+ - NCT05592626RecruitingPhase 1/Phase 2
T cell activator STAR0602 for advanced solid tumors
This study tests an experimental drug called STAR0602 that aims to boost your immune system's T cells to fight advanced solid tumors. It's for patients whose cancer has not responded to standard treatments or for whom such treatments are not suitable.
Sacramento, CaliforniaAges 18 years+ - 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 - NCT05877599RecruitingPhase 1
Study of a new treatment for advanced cancers with a specific gene change
This trial tests a new type of therapy (NT-175) for people with certain advanced cancers that have a specific genetic change. It might help if your tumor has the TP53 R175H mutation and you have the HLA-A*02:01 immune marker.
Duarte, CaliforniaAges 18 years+ - NCT04585750RecruitingPhase 1/Phase 2
Study drug for TP53 Y220C-mutated advanced cancers

What taking part in a colorectal neoplasms 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.
