Recruiting studies
- NCT06686576RecruitingPhase 3
Study of QL1706 before surgery for MSI-H colon cancer
This trial tests a new immunotherapy medicine (QL1706) given before surgery to treat colon cancer that hasn't spread yet. It's designed for patients whose tumors have a specific gene feature (MSI-H/dMMR) and who haven't had any prior treatment for this cancer.
GuangzhouAges 18–75 - NCT06490536RecruitingPhase 3
Testing a new treatment for high-risk colon cancer after surgery
This trial tests a new treatment approach for people with certain high-risk colon cancers (stage II or III in the upper colon) after surgery. It aims to see if adding a study drug can help prevent the cancer from coming back.
BerlinAges 18 years+ - NCT05713903Recruiting
Compare keyhole versus open surgery for right colon cancer
This trial compares two surgical approaches—keyhole surgery versus open surgery—for right colon cancer. It aims to see which approach works better and is safer for patients needing planned (elective) tumor removal.
LarissaAges 18–90 - NCT06368141RecruitingPhase 2
Chemo plus immunotherapy before surgery for colon cancer
This trial tests whether giving chemotherapy followed by an immunotherapy drug (a checkpoint inhibitor) before surgery helps shrink locally advanced colon cancer. It is for people with a specific tumor type (MSS and RAS mutation) who have not had prior treatment.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT06349642Recruiting
Testing a live tumor test for immune therapy response
This trial uses a special test on live tumor samples to see if it can predict how well immune checkpoint inhibitors (a type of immunotherapy) will work for different cancers. It may help doctors choose the best treatment for you.
Phoenix, ArizonaAges 18 years+ - NCT06287814Recruiting
Blood test to detect leftover cancer DNA in colorectal cancer patients
This study uses a simple blood test (liquid biopsy) to look for tiny bits of tumor DNA remaining after colorectal cancer surgery. It aims to see if the test can help predict whether the cancer will come back, especially in people with stage III cancer who will receive chemotherapy.
Montpellier, HéraultAges 18 years+ - NCT06197425RecruitingPhase 3
Extra chemotherapy after surgery for colorectal cancer with positive ctDNA
This trial tests whether giving more chemotherapy can help people who still have cancer DNA in their blood after surgery and standard chemotherapy for colorectal cancer. The goal is to prevent the cancer from coming back.
DijonAges 18–80 - NCT06111105Recruiting
Comparing blood tests to guide colon cancer treatment
This study compares different blood tests to find the best way to detect tiny bits of cancer DNA after surgery for stage III colorectal cancer. It aims to help doctors decide if additional chemotherapy is needed to prevent the cancer from coming back.
Graz, StyriaAges 18 years+ - NCT06076811Recruiting
Guiding colorectal cancer follow-up with a blood test
This trial uses a blood test (liquid biopsy) to look for tiny bits of cancer DNA remaining after surgery. It aims to see if this test can help guide follow-up and treatment decisions for people with colorectal cancer.
Copenhagen, Capital Region of DenmarkAges 18 years+ - NCT05923255Recruiting
Trial for surgery planning in right-side colon cancer
This trial studies how to treat cancers located near the right bend of the colon (hepatic flexure) or the first part of the transverse colon. It may help patients by testing a specific approach to surgery before and around the time of resection.
Bengbu, AnhuiAges 18–75 - NCT05855200RecruitingPhase 3
Dostarlimab around surgery for certain untreated colon cancers
This trial studies dostarlimab given around the time of colon cancer surgery for people with untreated, resectable (operable) stage T4N0 or stage III colon cancer that has specific tumor markers. It may help shrink or eliminate the cancer before or after surgery by boosting the immune response.
Tucson, ArizonaAges 18 years+ - NCT05394714RecruitingPhase 1
Magicell-NK cell therapy after colon cancer surgery
This early-stage trial tests an individualized immune cell treatment (Magicell-NK) made from your own cells to help prevent colon cancer from coming back after surgery. It studies safety and how well the treatment works in people with early-stage colon cancer.
TaoyuanAges 20 years+ - NCT05239546RecruitingPhase 2
Dostarlimab before colon surgery for mismatch-repair–deficient cancer
This study tests dostarlimab given before surgery for stage II or III colon cancer that has a specific DNA repair defect. It aims to shrink or control the cancer so that some people may be able to skip surgery if the results are good.
Iowa City, IowaAges 18 years+ - NCT05179889RecruitingPhase 2/Phase 3
Chemo after surgery for high-risk stage III colon cancer
This trial tests giving mFOLFIRINOX chemotherapy after curative surgery for people with high-risk stage III colon cancer. It aims to lower the chance that cancer comes back.
DaejeonAges 20–75 - NCT05174169RecruitingPhase 2/Phase 3
Adjuvant colon chemotherapy guided by tumor DNA results
This trial tests whether treatment for colon cancer after surgery can be guided by a blood test that looks for leftover cancer signals (ctDNA). It may help some people choose stronger or different chemo based on whether ctDNA is found after surgery.
Birmingham, AlabamaAges 18 years+ - NCT04916990Recruiting
Care program for rural adults with several lung and head cancers
This study looks at how to improve care for adults with certain cancers who live in rural areas and may face access problems. It mainly focuses on people receiving cancer treatment at specific Colorado-area hospitals, and who are uninsured or underinsured.
Aurora, ColoradoAges 18–99 - 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 - NCT04624555Recruiting
Check how well stool DNA tests help watch for colon cancer return
This trial studies whether an at-home stool DNA test (Mt-sDNA) can safely and usefully monitor people after colon or rectal cancer treatment. It’s mainly about whether the test is practical and helpful during routine follow-up.
Cleveland, OhioAges 18 years+ - NCT03819296RecruitingPhase 1
Fecal transplant to treat cancer immunotherapy bowel side effects
This early-phase study tests whether changing your gut bacteria with a fecal transplant can improve diarrhea or colitis caused by cancer immunotherapy. It may help people whose symptoms have not fully settled with standard treatments like steroids and other immune-blocking medicines.
Houston, TexasAges 18 years+ - NCT02172651RecruitingEarly Phase 1
Vitamin D during early colon cancer or liver surgery
This trial studies whether taking higher-dose vitamin D3 around the time of colon cancer (or colon cancer with resectable liver metastases) surgery improves outcomes. It focuses on safety and possible effects on cancer-related health after surgery.
Boston, MassachusettsAges 18 years+ - NCT07534852Recruiting
Nutrition and exercise support for colon cancer surgery patients
This study tests whether nutrition support and exercise help patients with early-stage colon cancer recover better after surgery. Researchers will provide dietary guidance and a supervised exercise program tailored to your needs.
Málaga, MalagaAges 18–75 - NCT03976960Recruiting
Database study for colon cancer surgery patients
This study collects clinical and lab information from people who have surgery for colon cancer (or certain precancer growths) and related spread to organs. It may help researchers better understand colon cancer and improve future care, but it is not a new medication trial.
Montpellier, HéraultAges 18 years+ - NCT06567782RecruitingPhase 2
Immunotherapy plus chemotherapy vs. chemotherapy alone for stage 3 colon cancer
This trial tests whether adding the immunotherapy drug dostarlimab to standard chemotherapy (CAPEOX) is more effective than chemotherapy alone for people with a specific type of colon cancer (MMRp/MSS) that has not spread. It is given before surgery to shrink the tumor.
AalstAges 18 years+ - NCT05344209RecruitingPhase 2
Pembrolizumab plus or minus vaccine for advanced lung cancer
This Phase 2 trial studies pembrolizumab (an immune-boosting cancer medicine) alone or with an added investigational UV1 vaccine in people with advanced non-small cell lung cancer. It aims to see whether adding the vaccine improves safety and effectiveness, especially in tumors with high PD-L1 levels.
