Biopsy after liver radiation to see tumor cell changes
This trial gives radiation to liver tumors and then takes a small tissue sample (biopsy) to look for changes in the cancer cells after treatment. The goal is to learn what the radiation is doing inside the tumor, which may help improve future treatments.
New York, New YorkAges 18 years+ - NCT04673955Recruiting
Real-world treatment study for metastatic bowel cancer with BRAF mutation
This real-world study looks at how doctors’ standard treatment works for metastatic colorectal cancer that has a specific BRAF mutation (BRAF V600E). It focuses on patients who are already starting—or will soon start—encorafenib plus cetuximab, using routine care rather than extra trial treatment.
Braunau am Inn, Upper AustriaAges 18 years+ - NCT04701476RecruitingPhase 2
Pembrolizumab for advanced colorectal or lung cancer
This study tests pembrolizumab (an immune system medicine) with another treatment (TATE) in people with advanced colorectal or lung cancer that is not driven by certain gene changes. It may help shrink tumors after standard chemotherapy has stopped working.
Orange, CaliforniaAges 18 years+ - NCT04722341Recruiting
Time-limited eating for people with certain breast or rectal cancers
This study tests whether eating only within a shorter daily time window can improve cancer outcomes in people with specific breast or rectal cancers. It also looks at how this affects the body (such as metabolism) and who is most likely to benefit.
Birmingham, AlabamaAges 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 - NCT04816292Recruiting
Compare removal of colon polyps with hot vs cold snare
This study compares two ways doctors remove certain colon polyps during colonoscopy: “hot snare” versus “cold snare.” It’s looking at whether one method removes polyps better and with fewer problems for people with polyps that are 10–15 mm.
München, BavariaAges 18–80 - NCT04842006Recruiting
Personalized treatment plan for rectal cancer before and after surgery
This trial looks at a personalized treatment approach for rectal cancer. It aims to guide the best chemotherapy and (if needed) radiotherapy before and after surgery, based on scans and specific test results.
Helsinki, UusimaaAges 18–100 - NCT04851119RecruitingPhase 1/Phase 2
Tegavivint for kids and young adults with hard-to-treat solid tumors
This early-phase study tests tegavivint to see how well it works and how safe it is for children and young adults with solid cancers that have come back or are not responding. It may be an option if your tumor type (including certain lymphomas or desmoid tumors) matches the study’s rules.
Birmingham, AlabamaAges 1–30 - NCT04861558RecruitingPhase 3
Warm chemotherapy placed in the abdomen to treat colon cancer
This Phase 3 trial tests whether heating chemotherapy and delivering it directly into the abdomen (along with standard surgery for cancer spread) works better for colon cancer that has spread to the lining of the abdomen. It may help control the cancer after surgery, especially when the spread is mainly in the abdomen (and possibly the liver or lungs).
AhmedabadAges 18–79 - NCT04895709RecruitingPhase 1/Phase 2
Testing a new cancer drug for advanced solid tumors
This early-phase trial tests how well a new drug (BMS-986340) works alone and combined with other treatments in people with advanced solid tumors that have progressed despite standard care. It also studies tumor samples to look for biomarkers that may predict who benefits.
Clovis, CaliforniaAges 18 years+ - NCT04899908RecruitingPhase 2
Brain radiation with or without gadolinium nanoparticles for brain metastases
This trial tests whether adding tiny gadolinium-containing nanoparticles to standard brain radiation can better control brain metastases from certain cancers. It is for people with tumors that have grown after immunotherapy, are from certain cancers (like melanoma, GI, or HER2+ breast), are cystic, are large, or have come back after prior radiation.
Boston, MassachusettsAges 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 - NCT04920032RecruitingPhase 1
Blood test–guided extra treatment for colon cancer recurrence risk
This Phase 1 study uses a blood test called ctDNA to decide whether and how to adjust treatment in people with colon cancer who still have a small amount of disease left after surgery. If your blood test remains positive, the trial aims to reduce recurrence risk by guiding treatment changes.
Orange, CaliforniaAges 18 years+ - NCT04920149RecruitingPhase 2
Mesalamine to help prevent colon cancer in Lynch syndrome
This trial tests whether mesalamine, a medicine used for bowel inflammation, can help prevent colorectal cancer in people with Lynch syndrome who do not currently have cancer. It may help by lowering the chance that new pre-cancer growths form over time.
AalborgAges 30 years+ - NCT04930432RecruitingPhase 1/Phase 2
MCLA-129 for advanced EGFR- and MET-positive lung and other cancers
This early-phase trial tests MCLA-129, an antibody that targets EGFR and MET, in people with advanced cancers that have specific lab “biomarker” results. It’s for patients whose cancer has grown after standard treatments or can’t take standard treatment, with the goal of shrinking tumors and improving symptoms.
BaodingAges 18 years+ - 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.
Gilbert, ArizonaAges 18 years+ - NCT04969315RecruitingPhase 1/Phase 2
Drug TT-10 and TT-4 for advanced solid tumors
This early-phase trial tests two investigational drugs—TT-10 and TT-4—alone and together in people with advanced solid cancers. The study is designed to find safe doses and see if the treatment can shrink tumors or slow cancer growth.
Los Angeles, CaliforniaAges 18 years+ - NCT04981119Recruiting
Test apheresis for CAR T manufacturing in HLA-A2 solid tumors
This trial studies how a process called apheresis is used to make CAR T cells for people with certain solid tumors. It is designed for tumors that have lost a specific immune marker (HLA-A*02), which may affect how well CAR T therapies work.
Gilbert, ArizonaAges 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+ - NCT05038358Recruiting
Study of immune and chemo resistance in colorectal tumors
This study looks at how the immune system around a colorectal tumor relates to resistance to chemotherapy. You may be able to join if you are having surgery soon for colorectal cancer and have not yet had chemotherapy before surgery.
GrenobleAges 18 years+ - NCT05041478Recruiting
Cold removal method for large colon polyps
This trial compares two cold endoscopic techniques to remove certain large, non-cancerous colon polyps with better control of bleeding and leftover tissue. You may be offered one of the two removal methods during your scheduled colonoscopy.
Westmead, New South WalesAges 18 years+ - NCT05086692RecruitingPhase 1/Phase 2
Beta-only IL-2 therapy for advanced solid tumors
This Phase 1/2 study tests a beta-only version of IL-2, an immune-stimulating treatment, to shrink or control advanced or metastatic solid tumors. It’s mainly designed to check safety and to see if it can help patients by improving tumor response.
San Diego, CaliforniaAges 18 years+ - NCT05102110Recruiting
Check rectal mucus in people with throat or lung cancers
This study looks at a substance called rectal mucus during an exam to learn about changes in people with cancers of the throat/airways (aero-digestive tract). It’s a feasibility study, meaning it mainly tests whether this approach is safe and practical.

- Are there clinical trials for colorectal?
- Yes. Clin2 currently lists 1,227 recruiting colorectal studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a colorectal trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a colorectal trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
