Rectal cancer surgery: with or without a temporary stoma
This trial compares two ways of doing rectal cancer surgery: one with a temporary stoma (a bag on the belly) and one without. It aims to see if a stoma helps prevent complications after the bowel is reconnected.
MoscowAges 18–70 - NCT07463573RecruitingPhase 3

Tegavivint for advanced colorectal cancer after other treatments
This early-phase trial tests an experimental drug called tegavivint for people with advanced colorectal cancer who have already tried several standard treatments. It aims to see if the drug can shrink or slow the growth of tumors.

Fecal transplant to prevent infections in severe pancreatitis
This trial tests whether a fecal microbiota transplant (FMT) can help prevent infections in people with moderately severe or severe acute pancreatitis. You may qualify if you are between 18 and 75, have had pancreatitis for 15 to 21 days, and already have a feeding tube in place.
Fuzhou, FujianAges 18–75 - NCT07464470Recruiting
Comparing stomach cancer and brain metastasis genetics
This trial studies stomach and esophageal cancers that spread to the brain. It compares the genetic makeup of the original tumor to the brain metastasis, which may help find better treatments.
MoscowAges 18 years+ - NCT07464626Recruiting
Art therapy for anxiety and sleep in colorectal cancer patients
This study compares virtual and in-person art therapy to help reduce anxiety, improve psychological well-being, and enhance sleep quality for people with colorectal cancer who are receiving chemotherapy.
Izmir, BalçovaAges 18 years+ - NCT07466238Recruiting
Chemo into the liver plus IV chemo for bile duct cancer
This trial is testing a treatment plan that first delivers chemotherapy directly into the liver (through a thin tube) along with standard IV chemotherapy. The goal is to shrink the tumor enough to allow for surgery or less aggressive treatment later. It is for people with bile duct or gallbladder cancer that has not spread far.
BeijingAges 18–80 - NCT07466602Recruiting
Using DNA to detect liver cancer return
This trial uses a blood test to check for signs of liver cancer coming back after treatment. It may help find recurrence earlier than standard scans.
Wuhan, HubeiAges 18 years+ - NCT07467213RecruitingPhase 3
Acid reflux drug for heart attack recovery
This trial tests if a newer acid-reducing drug is better than standard care for preventing stomach problems in people who recently had a heart attack and a stent placed. It could help those who need stomach protection while on blood thinners.
SeoulAges 19 years+ - NCT07467434Recruiting
Chemo before surgery for rectal cancer with liver spread
This trial tests if giving FOLFIRINOX chemotherapy first can improve outcomes for people with rectal cancer that has spread to the liver but can still be removed by surgery.
Le Kremlin-BicêtreAges 18 years+ - NCT07468630RecruitingPhase 2
Tocilizumab plus chemoimmunotherapy for advanced colon cancer
This study tests a new combination of medications for people with locally advanced colon cancer. It aims to see if adding tocilizumab to standard chemo-immunotherapy can help shrink or control the tumor.
Chongqing, Chongqing MunicipalityAges 18–80 - NCT07469319Recruiting
Liver cancer screening for people with cirrhosis
This study tests whether offering an ultrasound and a blood test (alpha-fetoprotein) every 6 months can help find liver cancer early in people with cirrhosis (scarred liver) caused by conditions other than hepatitis B or C. The goal is to reduce deaths from liver cancer in this group.
Aarhus, Central JutlandAges 40–79 - NCT07469709Recruiting
Cancer risk study using genetics and monitoring
This study looks at genetic and other factors in people with certain cancers to better understand personal cancer risks and improve monitoring. It may help find ways to detect changes earlier.
Candiolo, TurinAges 18 years+ - NCT07470502Recruiting
Study of infliximab for children and teens with IBD
This trial is looking at children and teenagers with Crohn's disease or ulcerative colitis who are starting a biologic medicine called infliximab. It aims to learn more about how this treatment works in young patients.
Florence, ItalyAges 3–18 - NCT07472686Recruiting
Capsule endoscopy for small bowel in Lynch syndrome
This study looks at how well a tiny camera in a pill (capsule endoscopy) can find early growths or cancer in the small intestine of people with Lynch syndrome. Lynch syndrome increases your risk for certain cancers, and this test might help catch them earlier.
ParisAges 18 years+ - NCT07473375Recruiting
Factors affecting portal vein clot reopening in cirrhosis
This study looks at factors that help open up blood clots in the main vein to the liver (portal vein) in people with cirrhosis and varices. It might help guide treatment to improve blood flow.
