Recruiting studies
- NCT05201430RecruitingPhase 3
FOLFOXIRI vs CapeOX before surgery for locally advanced rectal cancer
This trial compares two chemotherapy plans given before rectal cancer surgery to see which helps more people and works better for disease control. If you have locally advanced rectal cancer and have not had treatment yet, this study may be an option.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT04991948RecruitingPhase 1
Testing pembrolizumab after CYAD-101 plus FOLFOX in colon cancer
This early-phase study tests whether adding pembrolizumab after CYAD-101 and FOLFOX chemotherapy can help treat metastatic colon or rectal cancer. It is mainly looking for safety and signs of how well the treatment works in people whose cancer has not responded to prior therapy.
Jacksonville, FloridaAges 18 years+ - NCT04938986Recruiting
Testing a tumor marker to predict colon cancer relapse risk
This study looks at whether a lab test on your tumor can better predict the chance that non-metastatic colon cancer will come back after surgery. Researchers will compare relapse risk using the Immunoscore® test to help guide follow-up and treatment decisions.
MarseilleAges 18–80 - NCT05378919RecruitingPhase 2
Testing new pre-surgery treatment for locally advanced rectal cancer
This Phase 2 trial compares a pre-surgery (neoadjuvant) treatment plan versus the standard plan for people with stage II–III rectal cancer. The goal is to see which approach works better and is safe before surgery.
KaunasAges 18 years+ - NCT05300269RecruitingPhase 2
Test drug SHR-1701 with chemo and radiation for rectal cancer
This trial studies whether adding SHR-1701 to standard chemotherapy and long-course radiation can improve treatment for locally advanced rectal cancer that can be removed by surgery. It’s mainly for people who have not had prior rectal cancer treatment and who fit several health and cancer-spread requirements.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT05579353Recruiting
Study stool and blood markers in colorectal cancer treatment planning
This study looks at special tiny cell-signal particles (called exosomes) and related pathways to understand colorectal cancer. Your results from samples may help researchers learn how these signals relate to the disease after surgery.
Jinan, LixiaAges 18–80 - NCT04486131Recruiting
Test for treatment of recurrent rectal cancer in side lymph nodes
This trial focuses on rectal cancer that has come back in the side lymph nodes near the pelvis. It tests how to treat that “lateral nodal recurrence” to improve outcomes by targeting these specific lymph nodes.
Amsterdam, North HollandAges 18 years+ - NCT03466424Recruiting
Short radiation then chemotherapy for locally advanced rectal cancer
This trial tests a short course of radiation given before chemotherapy for people with locally advanced rectal cancer (cancer that has grown into nearby tissue and/or nearby lymph nodes but can still be removed). It may help shrink the tumor and make treatment more effective while assessing how well this approach works.
Fuzhou, FujianAges 18–70 - NCT04743102Recruiting
Multi-point full-thickness biopsy to confirm complete rectal cancer response
This trial checks whether taking small samples from the full thickness of rectal tissue can accurately confirm that rectal cancer has fully responded to chemotherapy and/or radiation. It may help doctors decide the best next step if no tumor is seen after treatment.
Beijing, Beijing MunicipalityAges 18–80 - NCT05725200RecruitingPhase 2
Personalized treatment plan for metastatic colon or rectal cancer
This Phase 2 trial tests an individualized treatment chosen from your tumor’s lab testing (genetic and RNA profile plus a drug-sensitivity test from your tumor cells). It may help by matching you to targeted anti-cancer drugs that are most likely to work for your specific cancer.
OsloAges 18 years+ - NCT05136326RecruitingPhase 2
Pre-surgery chemo-radiation for rectal cancer without MGMT
This trial studies whether adding two chemotherapy medicines (capecitabine and temozolomide) to standard pre-surgery chemo-radiation can work better for people with locally advanced rectal cancer that has a specific tumor marker pattern (MGMT “silenced”) and is mismatch-repair proficient (MSS). It aims to shrink the tumor before surgery and improve cancer control.
MilanAges 18 years+ - NCT04245683Recruiting
Testing non-surgical treatment for newly diagnosed rectal cancer
This study looks at whether it’s practical and safe to treat certain rectal cancers without surgery. You may be offered non-surgical (“neoadjuvant”) treatment and close follow-up to see how well it works in a rural setting.
Cooperstown, New YorkAges 18 years+ - NCT05939661RecruitingPhase 2
Total treatment before surgery for early rectal cancer
This Phase 2 study tests a “total neoadjuvant” approach, meaning you receive cancer treatment before surgery, to improve safety and effectiveness for rectal cancer. It may help by shrinking the tumor and planning a more effective operation, while researchers carefully track side effects.
OsakaAges 18 years+ - NCT05984485RecruitingPhase 3
Surgery vs chemo before surgery for low-risk rectal cancer
This trial compares two approaches for low-risk locally advanced rectal cancer: going straight to surgery (TME) versus receiving chemotherapy before surgery. The goal is to see if upfront surgery works just as well, sparing patients from chemotherapy side effects.
Chongqing, Chongqing MunicipalityAges 18–75 - NCT05450029RecruitingPhase 2
Adding immunotherapy to chemo-radiation for rectal cancer
This Phase 2 trial studies whether adding sintilimab (an immunotherapy drug) to standard chemo-radiation before surgery can improve outcomes for people with locally advanced rectal cancer. It’s aimed at tumors with certain immune “signature” scores and specific cancer stage features.
Guangzhou, GuangdongAges 18–75 - NCT06043999Recruiting
Chemotherapy vs. surgery for high-risk rectal cancer after local removal
This trial compares standard chemotherapy to more extensive surgery (total mesorectal excision) for patients whose initial local surgery showed high-risk features like poor differentiation, lymphovascular invasion, or larger tumor size. It aims to find the best treatment to prevent cancer from coming back.
Guangzhou, GuangdongAges 18–75 - NCT04616495Recruiting
Liver transplant for colorectal cancer that can’t be removed
This trial studies liver transplantation for people with colorectal cancer that has spread to the liver but cannot be surgically removed. It aims to see if transplant can improve outcomes when the cancer is limited to the liver.
ValenciaAges 18–65 - NCT02649647Recruiting
Surgery plan for rectal cancer after chemo-radiation
This trial looks at a specific type of rectal surgery after you’ve already finished chemo-radiation, aiming to remove the tumor while trying to preserve the anal sphincter (muscle control). It’s meant for people whose cancer can be safely operated on and who don’t have spread to distant organs.
Guangzhou, GuangdongAges 18–75 - NCT06176885RecruitingPhase 2
Immunotherapy plus chemo and targeted therapy for MSS colorectal cancer
This trial tests adding immunotherapy to standard chemotherapy and targeted therapy for people with metastatic colorectal cancer that is MSS (microsatellite stable) and cannot be removed with surgery. It aims to see if this combination helps shrink tumors and improve outcomes.
Jinhua, ZhejiangAges 18–75 - NCT06194708Recruiting
Why some temporary stomas are never reversed after rectal cancer surgery
This trial looks at why some people who had a temporary stoma (a bag for waste) after rectal cancer surgery never get it reversed. It collects information from medical records to find patterns that might explain this.
Beijing, Beijing MunicipalityAges 18–100 - NCT05245474RecruitingPhase 2
Before-surgery chemoradiation plus PD-1 for locally advanced rectal cancer
This trial studies giving long-course radiation and chemotherapy before surgery, plus an immunotherapy medicine (PD-1) to help the tumor shrink more. It’s for people with stage II or III rectal cancer that has not spread to distant organs.
Beijing, Beijing MunicipalityAges 18–75 - NCT07866313RecruitingPhase 2/Phase 3
Chemotherapy, radiation, and immunotherapy before surgery for low rectal cancer
This trial tests a new combination of chemotherapy, radiation, and immunotherapy given before surgery for low rectal cancer. It aims to see if this approach can shrink tumors and improve outcomes for patients with a specific type of cancer that is microsatellite stable (MSS).
Shanghai, Shanghai MunicipalityAges 18–75 - NCT06222255Recruiting
Transanal irrigation for sleep issues after rectal cancer surgery
This trial tests if a special irrigation technique can improve sleep problems caused by low anterior resection syndrome (LARS) after rectal cancer surgery. It may help people who have ongoing bowel symptoms that disrupt sleep.
Seoul, Jongro-guAges 19–80 - NCT06242067RecruitingPhase 2
Second-line treatment for advanced colorectal cancer
This trial tests a new treatment for people with advanced colorectal cancer that has spread or come back after initial chemotherapy. It is for those who have already received standard first-line therapy and are now looking for a second treatment option.
