Recruiting studies
- NCT06834126RecruitingPhase 1
Papaverine with radiation for advanced rectal cancer
This trial tests if adding papaverine (a drug) to radiation therapy can help people with locally advanced rectal cancer avoid surgery and keep their rectum. It is for patients who have already had chemotherapy and want a non-surgical approach.
Duarte, CaliforniaAges 18 years+ - NCT07198165RecruitingPhase 2
Short radiation followed by chemo plus bevacizumab with or without immunotherapy for rectal cancer
This trial tests whether adding an immunotherapy drug (PD-1 inhibitor) to standard chemoradiation and targeted therapy improves outcomes for locally advanced rectal cancer. It is for patients who have not had prior treatment and do not have certain genetic markers (BRAF mutation or MSI-H).
ShanghaiAges 18–75 - 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 - NCT06934538RecruitingPhase 1/Phase 2
Immunotherapy trial for advanced colorectal cancer
This trial tests a new immunotherapy drug (STC-1010) for people with colorectal cancer that cannot be removed by surgery or has spread. It aims to see if the drug can shrink tumors or slow the disease.
Baltimore, MarylandAges 18–75 - NCT07446322RecruitingPhase 2
Study of a new drug plus standard chemo for advanced colorectal cancer
This trial tests if adding the experimental drug pelareorep to standard chemotherapy (FOLFIRI) and bevacizumab can help people with a specific type of advanced colorectal cancer that has a RAS mutation and is not caused by high microsatellite instability. You may be able to join if you've already tried one type of chemotherapy and it stopped working or you couldn't tolerate it.
Homewood, AlabamaAges 18 years+ - NCT07207317Recruiting
LIRRH trial for right-sided colon cancer
This trial tests a treatment for people with right-sided colon cancer that has not spread. It aims to see if a specific surgery or approach can improve outcomes.
Shijiazhuang, HebeiAges 18–75 - NCT03803553RecruitingPhase 3
Testing blood tumor DNA treatment after stage III colon surgery
This trial studies how to find tiny hidden cancer cells after stage III colon cancer surgery using a blood test. If the blood test shows tumor DNA, you may get additional treatment to lower the chance of cancer coming back.
Boston, MassachusettsAges 18 years+ - NCT03853733Recruiting
Shorter radiation plan for non-surgery rectal cancer
This trial looks at a shorter radiation schedule for people with advanced rectal (or nearby sigmoid) cancer who cannot have surgery. The goal is to control the cancer while keeping treatment simpler, especially for those who cannot safely undergo an operation.
Terrassa, CataloniaAges 18 years+ - NCT04074538Recruiting
Colorectal cancer study to help researchers learn patterns
This study is collecting information from people with newly diagnosed colon or rectal cancer, to better understand the disease and support future research. It may help you and others by improving how colorectal cancer is studied and potentially treated over time.
Hangzhou, ZhejiangAges 18 years+ - NCT04389086RecruitingPhase 3
Chemotherapy before surgery for recurring rectal cancer
This trial tests an “induction chemotherapy” treatment before surgery for people whose rectal cancer has come back in the local area. The goal is to shrink/control the cancer early and improve outcomes after treatment.
GhentAges 18 years+ - NCT05495776Recruiting
Study checks how often Lynch syndrome happens in colon cancer
This registry study looks at how many people with colon cancer also have Lynch syndrome, an inherited condition that can affect cancer risk. If you enroll, your care team collects basic information from your diagnosis to better estimate how common it is.
MoscowAges 18 years+ - NCT05772923Recruiting
Testing rectal cancer organ-preservation after radiation
This trial compares two ways to preserve the rectum/avoid major surgery after radiation: a focused contact x-ray treatment versus waiting longer and then removing only a small area if needed. It may help some people keep more normal bowel function while still controlling the cancer.
Nijmegen, GelderlandAges 18 years+ - NCT06326879Recruiting
Comparing early vs late onset colorectal cancer
This study compares patients diagnosed with colorectal cancer at a younger age (under 50) to those diagnosed later in life. By looking at tissue samples and patient surveys, researchers hope to understand differences in the disease and improve care for all ages.
Rozzano, MIAges 18 years+ - NCT06741293Recruiting
Improving colorectal cancer early screening with stool tests
This study looks for markers in stool (poop) to detect colorectal cancer early. If you are between 40 and 74, live in the Lisbon area, and don't have certain digestive or cancer conditions, you may help improve screening by providing a stool sample.
Lisbon, Lisbon DistrictAges 40–74 - NCT06850090RecruitingPhase 3
Comparing two chemo drugs before radiation for rectal cancer
This trial tests if a newer chemo pill (TAS-102) works better than the standard pill (capecitabine) when given before radiation and surgery for rectal cancer. It is for people with stage II or III rectal cancer that has certain high-risk features.
Jinan, ShandongAges 18–75 - NCT06936774RecruitingPhase 3
Intensive follow-up after rectal cancer surgery to improve recovery
This study tests whether a more intensive follow-up program after rectal cancer surgery can improve your recovery, daily function, and overall quality of life. If you've had a temporary ileostomy and are waiting for reversal, this extra support may help you feel better faster.
BaselAges 18 years+ - NCT06992648RecruitingPhase 3
Two drug combos for advanced colorectal cancer
This trial tests a two-drug combination (trifluridine/tipiracil plus regorafenib) against a standard pair (trifluridine/tipiracil plus bevacizumab) for people with advanced colorectal cancer that has stopped responding to prior treatments. It aims to find which combination works better.
Hangzhou, ZhejiangAges 18 years+ - NCT07176182RecruitingPhase 2
Chemotherapy with alvenor for rectal cancer with high YWHAB
This trial tests adding the drug alvenor to standard chemotherapy before surgery for rectal cancer patients whose tumors have high levels of a protein called YWHAB. The goal is to see if this combination can improve treatment outcomes.
Guangzhou, GuangdongAges 18–75 - NCT07244705RecruitingPhase 1/Phase 2
Study of ABT-301 plus tislelizumab and bevacizumab for advanced colorectal cancer
This trial tests a new drug combination (ABT-301, tislelizumab, and bevacizumab) for people with a specific type of advanced colorectal cancer that has not responded to at least two prior treatments. It aims to see if this combination can help shrink tumors or slow the disease.
Liverpool, New South WalesAges 18 years+ - NCT07528209RecruitingPhase 3
Chemotherapy with or without immunotherapy for advanced rectal cancer
This study tests whether adding an immunotherapy drug (pucotenlimab) to standard chemotherapy (CAPOX) before surgery helps treat locally advanced rectal cancer better. The goal is to shrink tumors and improve survival while preserving bowel function when possible.
Guangzhou, GuangdongAges 18–75 - NCT06411691RecruitingPhase 1
Vaccine plus immunotherapy for KRAS-mutant cancers
This trial tests a cancer vaccine designed to target KRAS-mutated tumors, combined with two immunotherapy drugs, for people with advanced colorectal or pancreatic cancer. It may help the immune system recognize and attack cancer cells.
Baltimore, MarylandAges 18 years+ - NCT06559059Recruiting
Virtual cancer program for Veterans with new cancer
This study looks at how well a virtual (telemedicine) cancer program works for Veterans who are newly diagnosed with lung, prostate, breast, or colon cancer. Participation involves a telemedicine visit at a VA medical center instead of traveling to the hospital.
Brooklyn, New YorkAges 18 years+ - NCT07318805RecruitingPhase 1
A study of PF-08032562 for advanced solid tumors
This study tests a new medicine, PF-08032562, for people with advanced breast or colorectal cancer that has not responded to prior treatments. It aims to see if the drug is safe and can help shrink or slow the cancer.
Duarte, CaliforniaAges 18 years+ - NCT04854213Recruiting
Study checks radiation effects in colon cancer lung-limited spread
This trial studies how targeted radiation (SBRT) affects cancer biology and immune cells in people with colon cancer that has spread only to a small number of lung nodules. Your tumor tissue will be analyzed to see what changes after treatment.
