Recruiting studies
- NCT07239466RecruitingPhase 2
Ketone supplement with radiation and chemo for rectal cancer
This study tests a combination of a special diet supplement (beta-hydroxybutyrate), short radiation therapy, immunotherapy, and chemotherapy before surgery for locally advanced rectal cancer. The goal is to see if this approach helps shrink the tumor and improve treatment outcomes.
Wuhan, HubeiAges 18–75 - 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 - 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 - NCT06928584RecruitingPhase 2
Shorter Radiation Plus Immunotherapy for Recurrent Rectal Cancer
This trial tests whether a shorter, higher-dose radiation course (hypofractionated) combined with immunotherapy works better than standard radiation for locally recurrent rectal cancer that hasn't spread elsewhere. It's for people who haven't had chemotherapy or recent pelvic radiation.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT07209787RecruitingPhase 4
Reinforced vs. standard connection for rectal cancer surgery
This trial tests whether a special reinforcement patch (made from pig tissue) can reduce the risk of leaks when the rectum is reconnected after rectal cancer surgery. It compares the reinforced connection to the standard method.
Beijing, Beijing MunicipalityAges Up to 85 years - NCT07194616Recruiting
Rectal cancer blood test study before surgery
This trial is studying a blood test (CTC) for people with rectal cancer that hasn't spread to other parts of the body. It aims to see how the test relates to treatment outcomes after surgery.
OlomoucAges 18 years+ - NCT07183865RecruitingPhase 2
Radiation, chemo, and immunotherapy for recurrent rectal cancer
This trial tests a new combination of radiation, chemotherapy (NALIRIF), and an immunotherapy drug (PD-1 antibody) for rectal cancer that has come back in the pelvis. The goal is to see if this approach can help control the cancer better.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT07188025RecruitingPhase 3
Cancer DNA test to guide chemo after rectal cancer surgery
This trial tests whether checking for tumor DNA in your blood after surgery can help decide if you need additional chemotherapy. If the test finds cancer DNA, you may get chemo to lower the risk of the cancer coming back.
's-HertogenboschAges 18 years+ - NCT05965531RecruitingPhase 2
TAS-102 plus radiation before surgery for rectal cancer
This trial studies whether adding TAS-102 (a chemotherapy medicine) to radiation given before treatment improves outcomes for certain locally advanced rectal cancers. It may help by trying to shrink the tumor before the next steps of care.
Guangzhou, GuangdongAges 18–70 - NCT07177742Recruiting
Study of protein in blood to predict liver spread of colon cancer
This study looks at whether a substance in your blood (called PRDX1, found in tiny particles called exosomes) can help predict if colon cancer will spread to the liver after surgery. It may help doctors understand who needs more monitoring or treatment.
Shanghai, Shanghai MunicipalityAges 1.6 years–6.7 years - NCT07150949RecruitingPhase 2
Comparing two radiation schedules with chemotherapy and immunotherapy for rectal cancer
This study tests two different radiation regimens (long-course vs. short-course) combined with chemotherapy (CAPOX), an immunotherapy drug (PD-1 antibody), and a COX-2 inhibitor for people with MSS locally advanced rectal cancer. The goal is to see which approach works better in shrinking the tumor before surgery.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT06090994RecruitingPhase 4
Huaier vs capecitabine to prevent colon cancer return
This study compares two medicines to prevent colorectal cancer from coming back after surgery: a traditional Chinese medicine called Huaier and a standard chemotherapy pill called capecitabine. It is for people with stage 2 colon cancer that was completely removed.
Harbin, HeilongjiangAges 18 years+ - NCT07132463RecruitingPhase 3
Study of extra treatment for ultra-low rectal cancer
This trial tests if adding an immunotherapy drug (tislelizumab) to standard chemoradiation and chemotherapy helps patients with ultra-low rectal cancer. It is for patients whose cancer has not spread and can be removed with surgery.
ShanghaiAges 18–75 - NCT03401294RecruitingPhase 2
Turn unresectable liver cancer into operable colorectal cancer
This Phase 2 study tests a treatment strategy to shrink or control colorectal cancer that has spread only to the liver, with the goal of making it removable by surgery. If you qualify, it may offer a chance to move from “not operable” to “operable,” but it’s still experimental.
Regina, SaskatchewanAges 18–70 - 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 - NCT07108127RecruitingPhase 2
Targeted drugs plus chemo for HER2-positive rectal cancer
This trial tests whether a combination of two targeted drugs (trastuzumab and pertuzumab biosimilars) plus chemotherapy can shrink advanced HER2-positive rectal cancer before surgery. It aims to improve response and potentially reduce the need for more aggressive treatments.
BeijingAges 18 years+ - NCT07113275RecruitingPhase 3
Short versus long radiation schedule for advanced rectal cancer
This study compares two different schedules of radiation (a short course versus a longer course) followed by standard chemotherapy and immunotherapy for advanced rectal cancer. It aims to see which approach works best to shrink the tumor before surgery.
Wuhan, HubeiAges 18–75 - NCT07112937Recruiting
Effect of rectal cancer treatment on tumor cells in blood
This study looks at how different treatments for rectal cancer affect tumor cells that travel in your blood. It is an observational study, meaning you will not receive any new treatment, but your blood will be tested to help doctors learn more.
OstravaAges 18 years+ - NCT07095439RecruitingPhase 2
Sandwich treatment for stage 2 and 3 rectal cancer
This trial tests a new way of giving radiation and chemotherapy before surgery for rectal cancer that hasn't spread. It aims to see if this 'sandwich' approach is safe and works better than standard treatment.
CairoAges 18–70 - NCT07087561Recruiting
Nutrition and health education after colorectal cancer surgery
This trial tests whether a short-term nutritional supplement combined with health education can improve recovery after surgery for colorectal cancer. It is for people with stage IIa, IIb, or IIIa colon or rectal cancer who have completed surgery and are able to engage in follow-up.
Xi'an, ShaanxiAges 18 years+ - NCT07079631RecruitingPhase 1/Phase 2
Testing BNT314 with pumitamig and chemo for advanced colorectal cancer
This trial tests a new combination of drugs (BNT314 and pumitamig) plus chemotherapy for people with advanced colorectal cancer that has not responded to prior treatments. The goal is to see if this combination is safe and helps shrink or control the cancer.
New Haven, ConnecticutAges 18 years+ - NCT06214988Recruiting
Temporary stoma or not for rectal cancer surgery
This trial tests whether a temporary stoma (a bag on the belly) can be safely avoided in some people having rectal cancer surgery. The goal is to see if it's okay to skip the stoma in those with a low risk of complications.
MalmöAges 18 years+ - NCT07070622RecruitingPhase 3
Organ preservation for low rectal cancer after chemo
This trial tests whether chemotherapy alone can help avoid surgery for low rectal cancer. It is for people with tumors close to the anus that haven't spread far, and who haven't had prior cancer treatment.
Chengdu, SichuanAges 18–80 - NCT07068763RecruitingPhase 2
Short radiation plus drugs for early rectal cancer
This trial tests a combination of short-course radiation, chemotherapy (capecitabine), and two immunotherapy drugs (PD-1 and CTLA-4 inhibitors) for people with early-stage rectal cancer who want to avoid surgery and keep their anus. The goal is to see if this treatment can shrink the tumor enough to avoid major surgery.
