Comparing Vonoprazan vs. Pantoprazole for GERD
This trial tests a newer medication called vonoprazan against the standard treatment pantoprazole for patients with gastroesophageal reflux disease (GERD). The goal is to see which one works better for controlling symptoms like heartburn and acid reflux over 8 weeks.
GizaAges 17–60 - NCT06712095Recruiting
Video Capsule for Lynch Syndrome Screening
This study tests whether a video capsule (a pill-sized camera you swallow) can help find polyps in people with Lynch syndrome, without needing a colonoscopy. It may be an easier way to screen for colon cancer.
London, (Select)Ages 18 years+ - NCT06718530Recruiting
Finding early markers for liver cancer in people with chronic liver disease
This study looks for substances in your blood and immune system that could help doctors find liver cancer earlier. It is for people with liver cancer caused by chronic liver problems like hepatitis C, cirrhosis, or scarring.
Aviano, PordenoneAges 18 years+ - NCT06718205RecruitingPhase 2
Nimotuzumab plus immunotherapy and chemo for esophageal cancer
This study tests a new combination of drugs for advanced esophageal cancer. It adds an antibody (nimotuzumab) and an immunotherapy (sintilimab) to standard chemotherapy, aiming to improve how well treatment works.
Zhengzhou, HenanAges 18–75 - NCT06717542Recruiting
Liver tissue analysis to predict transplant success
This study looks at liver tissue before transplantation to find ways to predict how well the transplant will work. It involves a special treatment called HOPE to help preserve the liver.
BolognaAges 18 years+ - NCT06718153Recruiting
Using protein tests to diagnose liver cancer types
This trial uses special stains on tumor tissue to find genetic changes in liver cancer cells. It may help doctors better diagnose and classify the type of liver cancer you have.
BolognaAges 18 years+ - NCT05185739RecruitingPhase 2
Pembrolizumab and lenvatinib before liver surgery for resectable cancer
This trial tests whether giving pembrolizumab (an immune therapy) and lenvatinib (a targeted pill) before planned liver surgery can improve outcomes for people with certain types of operable hepatocellular carcinoma (HCC). It’s meant for tumors that can be removed with curative intent, but still carry a risk of coming back.
BirminghamAges 18 years+ - NCT06717828Recruiting
Tai Chi for fatty liver in older adults
This trial tests whether Tai Chi, a gentle exercise, can improve fatty liver disease in middle-aged and older adults who are overweight. If you are between 40 and 75 and have metabolic fatty liver, you might be able to join.
Fuzhou, FujianAges 40–75 - NCT06718738RecruitingPhase 1
IM96 CAR-T for advanced colorectal cancer
This trial tests a new cell therapy called IM96 CAR-T, which targets a protein (GUCY2C) found on tumor cells. It is for people with advanced colorectal or stomach cancer that has not responded to standard treatments.
Beijing, Beijing MunicipalityAges 18–75 - NCT05606523Recruiting
Test gut bacteria treatment for weight loss in pancreatic cancer
This study looks at how changing the gut microbiome (gut bacteria) may help people with pancreatic cancer regain strength and slow or reverse cancer-related weight loss (cachexia). It also studies gut bacteria differences in people with pancreatic cancer who are losing weight versus those whose weight is stable, and in healthy volunteers.
GenevaAges 18 years+ - NCT07593352Recruiting
Kidney Health in Inflammatory Bowel Disease Patients
This study compares kidney function between people with inflammatory bowel disease (IBD) and those without it. Researchers want to understand if IBD affects the kidneys and why, which could help protect kidney health in IBD patients.
Warsaw, WarszawaAges 18–80 - NCT07589465Recruiting
Lactulose to Help Digestion Recover After Appendix Surgery
This study tests whether taking lactulose (a gentle laxative) after appendix removal helps your stomach and intestines work normally again. The trial compares lactulose to a placebo (inactive pill) to see which helps patients recover bowel function faster.
SichuanAges 18 years+ - NCT07588386Recruiting
Early Colonoscopy After Low Rectal Cancer Surgery
This study tests whether doing a colonoscopy (camera exam of the colon) early after surgery for low rectal cancer helps catch a serious complication called anastomotic leakage—when the surgical connection between bowel segments breaks down. Early detection might help prevent severe infections and improve outcomes.
Nanchong, SichuanAges 18–80 - NCT07589205RecruitingPhase 1
