Aurora, ColoradoAges 45–75 - NCT06569368RecruitingPhase 2
Metronidazole with rectal cancer treatment
This trial tests adding the antibiotic metronidazole to standard pre-surgery therapy for locally advanced rectal cancer. The goal is to see if changing the bacteria in your gut can make the cancer treatment work better.
Houston, TexasAges 18 years+ - NCT05938322Recruiting
Ketogenic diet during pelvic cancer radiation treatment
This trial studies whether a very low-carbohydrate (ketogenic) diet can be followed safely while you receive neoadjuvant radiation for locally advanced rectal cancer. It may help researchers understand effects related to nutrition and treatment tolerance during radiation.
RomeAges 18–75 - NCT06364371Recruiting
Predicting rectal cancer treatment response using multi-omics
This trial is testing a new way to predict how well your rectal cancer will respond to treatments given before surgery. It uses advanced tests (like looking at genes and other markers) to tailor your care.
Guangzhou, GuangdongAges 18–80 - NCT06312982RecruitingPhase 2/Phase 3
Chemo, radiation, and immunotherapy before rectal cancer surgery
This trial tests whether a combination of chemotherapy, radiation, and an immunotherapy drug (tislelizumab) before surgery can improve outcomes for people with locally advanced rectal cancer that has specific protein/gene markers (pMMR or MSS). It’s designed for those who have not yet had any treatment for their cancer.
Beijing, Beijing MunicipalityAges 18–75 - NCT06055439RecruitingPhase 1/Phase 2
CAR T cell therapy for GI cancers
This trial tests a new type of immunotherapy called CAR T cells that target a protein (CDH17) found on certain stomach, colon, and rectal cancers. It's designed for people whose cancer has spread and has been treated before.
Atlanta, GeorgiaAges 18–85 - NCT05984875Recruiting
Immune system study for ovarian cancer
This study looks at how the immune system works in people with epithelial ovarian cancer. It aims to understand the immune landscape around the tumor, which could lead to better treatments in the future.
BellinzonaAges 18 years+ - NCT06002789RecruitingPhase 2
PD-1 immunotherapy with or without chemo before surgery for colorectal cancer
This trial tests a medicine called PD-1 (a type of immunotherapy that helps your immune system fight cancer), sometimes with chemotherapy, before surgery for a certain type of colorectal cancer. It is for people whose tumors have a specific DNA repair problem (dMMR or MSI-H) and whose cancer has not spread to distant organs.
Guangzhou, GuangdongAges 18–80 - NCT05943444Recruiting
Compares two ways to preserve bowel function after rectal surgery
This trial compares two surgical techniques to see which one better preserves anal function after surgery for low rectal cancer. If you may be eligible for anal-preserving surgery, it may help your care team choose the approach that best protects bowel control.
Guangzhou, GuangdongAges 18–75 - NCT05826743Recruiting
Check a new alternative to ileostomy after bowel surgery
This trial tests whether a device called COLO-BT can be a safer, effective alternative to an ileostomy (a temporary or longer-term opening from the intestine to the skin). It’s for certain adults having a bowel connection low in the pelvis, where leak risk matters.
Buffalo, New YorkAges 19–80 - NCT05752136RecruitingPhase 3
Pre-surgery radiation plus immunotherapy and chemo for rectal cancer
This trial tests whether a short course of radiation before surgery, combined with the immunotherapy drug envafolimab and the chemo regimen CAPEOX, works better for shrinking locally advanced rectal cancer. It is aimed at people whose tumor is not “MMR-deficient” (it is pMMR/MSS), and it asks participants to be able to return for repeated checkups and treatments.
Hangzhou, ZhejiangAges 18 years+ - NCT05772481Recruiting
PET-MRI scan test for rectal cancer after pre-surgery treatment
This study looks at whether a special scan called PET-MRI can better show how rectal cancer responds to treatment given before surgery. If it works well, it could help doctors plan the right next steps after chemoradiotherapy.
StrasbourgAges 18–75 - NCT05731726RecruitingPhase 2
New treatment before surgery for locally advanced rectal cancer
This trial tests whether giving serplulimab (an immune medicine) plus CAPEOX chemotherapy and celecoxib before surgery can shrink locally advanced rectal cancer and improve outcomes. It may help by increasing immune attack on the tumor while chemotherapy helps reduce the cancer before the operation.
Hangzhou, ZhejiangAges 18–75 - NCT05496491Recruiting
