Beijing, Beijing MunicipalityAges 40 years+ - NCT05528783Recruiting
Testing FIT-DNA to guide follow-up after colon cancer surgery
This trial checks a stool test called FIT-DNA after colorectal (colon) cancer surgery. It aims to see whether this test can help doctors monitor for recurrence during follow-up and decide how closely to watch.
Guangzhou, GuangdongAges 18–80 - NCT05571644RecruitingPhase 2
Study compares two pre-surgery treatments for locally advanced rectal cancer
This Phase 2 trial tests whether a newer combination chemotherapy plus an immunotherapy medicine (cadonilimab/AK104) works better than standard chemotherapy before surgery for locally advanced colorectal cancer. The goal is to shrink the tumor and improve how well treatment works after surgery.
Guangzhou, GuangdongAges 18–70 - NCT05577143Recruiting
Blood test screening for colorectal cancer
This study checks whether a blood test can help identify colorectal cancer or precancerous growths. You would have a planned colonoscopy, and researchers compare the blood test results to what the colonoscopy finds.
LilleAges 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 - NCT05639413Recruiting
Study of biology in people with BRAF V600E metastatic colon cancer
This study follows people with BRAF V600E–positive metastatic colorectal (colon) cancer to better understand how the cancer’s biology changes over time. It may help researchers learn which features to watch and how this cancer behaves after initial treatment.
AvignonAges 18 years+ - NCT05655780Recruiting
Irinotecan care guided by tumor genes and gut bacteria
This study looks at whether a patient’s tumor genetic makeup and gut bacteria activity can predict how well irinotecan-based treatment works and what side effects they might have. It may help personalize treatment to improve survival and quality of life for people with metastatic or unresectable colon cancer.
Maastricht, LimburgAges 18 years+ - NCT05663203Recruiting
Web-based support program for colorectal cancer patients and caregivers
This trial tests a web-based coaching/support program done together by you and your main caregiver. It may help by addressing common emotional and brain-related symptoms during active chemotherapy.
Atlanta, GeorgiaAges 18 years+ - NCT05676190Recruiting
Cell therapy using your own immune cells for colorectal cancer
This trial studies an immune cell treatment made from your own blood cells to treat colorectal cancer that has spread or progressed. You may be eligible if you have stage III–IV disease that can be measured on scans and if standard treatments have not worked or couldn’t be tolerated.
Chongqing, Chongqing MunicipalityAges 18–70 - NCT05677269Recruiting
Compare surgery for bowel endometriosis versus IVF pathway
This trial studies whether surgically removing colorectal (bowel) endometriosis works better and is more cost-effective than choosing an IVF/ICSI treatment plan. It’s for people who want to get pregnant and are deciding between surgery and fertility treatments.
EindhovenAges 21–40 - NCT05692024RecruitingPhase 1/Phase 2
Coffee and gut bacteria study after colon or rectal cancer
This early-phase study tests whether a coffee-related approach can change gut bacteria and blood “metabolites” after treatment for stage I–III colon or rectal cancer. The goal is to learn if these changes could help improve health after standard cancer treatment.
Boston, MassachusettsAges 18 years+ - NCT05710809Recruiting
Exercise and health check study for older colorectal cancer patients
