Recruiting studies
- NCT07023289RecruitingPhase 2
Study of Telisotuzumab Adizutecan for ctDNA-Positive Colorectal Cancer

Huntsville, AlabamaAges 18 years+ - NCT06326892Recruiting
Natural opening extraction in low rectal cancer surgery
This trial looks back at patients who had surgery for low rectal cancer using a technique where the removed tissue is taken out through a natural opening (like the anus) instead of through a separate cut in the belly. It aims to see how well this approach works.
Rozzano, MIAges 18 years+ - NCT06331988Recruiting
Study of colon cancer, bacteria, and the immune system
This study looks at how bacteria in your gut, your immune system, and colon cancer interact. It aims to understand these connections to improve future treatments.
MilanAges 18–75 - NCT06341296RecruitingPhase 2
Irinotecan liposomes for first-line advanced colorectal cancer
This trial tests a new type of chemotherapy (irinotecan liposomes) as a first treatment for metastatic colorectal cancer that has not been treated before. It focuses on patients with specific genetic changes (RAS or BRAF V600E mutation) or right-sided colon cancer, and looks at how well the drug works.
Sichuan, Sichuan, ChengduAges 18–85 - NCT06349590RecruitingPhase 1/Phase 2
Diet before colon cancer surgery to reduce recurrence
This trial tests whether a specific diet before colon cancer surgery can change the bacteria in your gut to help prevent the cancer from coming back or spreading. Patients who are eligible will follow the diet for a short time before their operation.
Chicago, IllinoisAges 18 years+ - NCT06380101Recruiting
Special diet with standard therapy for rectal cancer
This trial tests a special medical food that limits certain amino acids (building blocks of protein) during standard treatment for rectal cancer. The goal is to see if this diet helps the treatment work better while reducing side effects.
Tampa, FloridaAges 18–100 - NCT06455124RecruitingPhase 2
Short radiation and chemo-immunotherapy for early rectal cancer after local surgery
This trial tests a combination of short-course radiation, chemotherapy (CapeOx), and an immunotherapy drug (PD-1 inhibitor) for people with early-stage rectal cancer who have had a local excision but are at high risk of the cancer coming back. The goal is to avoid more extensive surgery while still effectively treating the cancer.
ShanghaiAges 18–75 - NCT06501053Recruiting
Contact X-ray therapy for early rectal cancer
This trial tests a special type of contact X-ray (brachytherapy) for early-stage rectal cancer. It may help avoid major surgery by treating the tumor from inside the rectum.
Stockholm, SolnaAges 18 years+ - NCT06547203RecruitingPhase 2
Cetuximab, irinotecan, and toripalimab for right-sided colorectal cancer
This trial tests a combination of three drugs (cetuximab, irinotecan, and toripalimab) for people with advanced right-sided colon cancer that does not have certain gene mutations. It's for those whose cancer has gotten worse after standard treatments.
Guangzhou, GuangdongAges 18–80 - NCT06566755RecruitingPhase 3
New drug combo for a common type of colorectal cancer
This trial tests a combination of a new immunotherapy (cadonilimab) with standard chemotherapy (capecitabine, oxaliplatin) and bevacizumab for people with metastatic colorectal cancer that has a RAS mutation or is located on the right side of the colon. The goal is to see if this combination works better than the current standard of care as a first treatment.
Shenyang, LiaoningAges 18–75 - 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+ - NCT06647680RecruitingPhase 2
Chemo and immunotherapy before surgery for rectal cancer
This trial tests a combination of chemotherapy and an immunotherapy drug (a PD-1 inhibitor) given before surgery for locally advanced rectal cancer. The goal is to see if this approach can improve outcomes compared to standard treatment.
Qingdao, ShandongAges 18–75 - NCT06689293Recruiting
Stool test for follow-up after colorectal cancer treatment
This trial is testing whether a simple stool test (FIT) can replace some follow-up colonoscopies or CT scans for people who have been treated for colorectal cancer. If you are due for a routine check-up after your cancer surgery, you may be able to take this test at home instead of having a more invasive procedure.
NottinghamAges 18 years+ - NCT06698757RecruitingPhase 2
Testing different cycles of sintilimab before surgery for colorectal cancer
This trial tests how many cycles of the immunotherapy drug sintilimab given before surgery help treat colorectal cancer that is mismatch repair deficient (dMMR) or microsatellite instability-high (MSI-H). It is for locally advanced cancer that has not spread to other parts of the body.
Zheng'zhou, HenanAges 18–75 - NCT07687875RecruitingPhase 1
Virus therapy plus immunotherapy before surgery for rectal cancer
This trial tests a combination of a cancer-killing virus (oncolytic virotherapy) and an immunotherapy drug (pembrolizumab) given before surgery for a certain type of rectal cancer. It aims to see if this approach helps shrink the tumor and improve outcomes for patients whose tumors have a normal DNA repair system (pMMR).
Copenhagen, Captial RegionAges 18 years+ - NCT07106034RecruitingPhase 2
Testing a new combo therapy for advanced colorectal cancer
This trial tests a combination of two drugs (ONGERICIMAB and TORIPALIMAB) for people with a specific type of colorectal cancer that did not respond to first treatment. It aims to see if this new approach can help shrink or control the cancer.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT07686133Enrolling by invitation
Digital education for colon and rectal cancer patients
This trial tests a digital education program for patients with colon or rectal cancer who are scheduled for surgery. It aims to see if online learning helps people better prepare for their operation and recovery.
TorontoAges 18 years+ - NCT06718543RecruitingPhase 2
Short-course radiation with AK112 for rectal cancer before surgery
This trial tests whether combining short-course radiation with an immune therapy drug (AK112) plus chemotherapy before surgery is better than radiation alone for locally advanced rectal cancer. It aims to shrink tumors and improve outcomes without needing stronger treatments later.
Chongqing, Chongqing MunicipalityAges 18–80 - NCT06719414Recruiting
Using a special MRI to predict rectal cancer response to pre-surgery therapy
This trial uses a special type of MRI scan (called amide proton transfer-weighted imaging) to look at your rectal cancer before and after chemotherapy and/or radiation. The goal is to see if the scan can predict whether the cancer has completely disappeared by the time of surgery, which could help guide future treatment decisions.
Guangzhou, GuangdongAges Any age - NCT06728072RecruitingPhase 2
Adding antibiotics to first chemo for advanced colorectal cancer
This trial tests whether adding a short course of antibiotics to your standard first chemotherapy for stage 4 colorectal cancer can improve treatment. The antibiotics target certain gut bacteria that might affect how well the chemo works.
Richmond, VirginiaAges 18 years+ - NCT06740357Recruiting
Shared decision-making for rectal cancer organ preservation
This trial tests a program that helps you and your doctor decide together whether to avoid surgery and keep your rectum after chemo and radiation. It's for people with early-stage rectal cancer who have not had prior treatment for this cancer.
DijonAges 18–80 - NCT06831981Recruiting
Heat therapy with chemo and radiation for rectal cancer
This trial tests if adding heat therapy (hyperthermia) to standard chemotherapy and radiation helps treat rectal cancer that has high-risk features. Heat therapy is thought to make cancer cells more sensitive to treatment.
Tübingen, Baden-WurttembergAges 18 years+ - NCT06846268RecruitingPhase 2
New drug combo before surgery for colorectal cancer

- 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 (colon or rectal) cancer 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.
