Using ultrasound and blood tests to predict varices risk in cirrhosis
This trial tests if a special ultrasound technique combined with liver stiffness and platelet count can predict which patients with cirrhosis have high-risk varices in the esophagus or stomach, potentially reducing the need for repeated endoscopy.
Changchun, JilinAges 18 years+ - NCT07150546RecruitingPhase 1
Radiation and Peptide Therapy for Large Gut Neuroendocrine Tumors
This trial combines external radiation with a targeted radioactive drug (PRRT) to treat large, slow-growing neuroendocrine tumors in the gut that have spread and are not removable by surgery. It aims to see if this combination works better than either treatment alone.
Atlanta, GeorgiaAges 18 years+ - NCT07148583Recruiting
BioAmicus Complete for tummy troubles in babies
This study tests if a probiotic supplement called BioAmicus Complete can help babies with common digestive issues like colic, reflux, constipation, or loose stools. It might be a good option if your baby has these symptoms and you haven't used other probiotics or antibiotics recently.
Haiphong, Hai PhongAges birth–2 years - NCT07154316RecruitingPhase 2
Short radiation plus drugs for MSS rectal cancer
This trial tests a shorter course of radiation therapy followed by a combination of chemotherapy, immunotherapy, and a pain-relief medication, compared to the standard approach. It is for people with a certain type of rectal cancer that has not spread.
Fuzhou, FujianAges 18–75 - NCT07151105Recruiting
Vitamin C for gut health in adults with obesity
This trial tests whether taking vitamin C supplements helps improve gut barrier function in adults with obesity. You'll follow a low-fruit-and-vegetable diet for two, two-week periods.
Columbus, OhioAges 18–50 - NCT07146165Recruiting
New tool for removing large growths in the rectum and lower colon
This trial tests a new platform to help doctors remove large polyps or early-stage cancers from the rectum and lower colon using a scope (endoscope). The goal is to see if this tool makes the removal process safer and more effective.
Freiburg im BreisgauAges 18 years+ - NCT07147335Recruiting
Blood test for early liver cancer warning in cirrhosis
This study looks at whether a blood test for a protein called AKR1B10 can help give early warning of liver cancer (hepatocellular carcinoma) in people with cirrhosis. If you have cirrhosis or chronic hepatitis and are between 18 and 75 years old, you may be able to join.
Hengyang, HunanAges 18–75 - NCT07154173Recruiting
Gut bacteria study in metastatic colorectal cancer
This study looks at gut bacteria in people with colorectal cancer that has spread (metastatic). It aims to find patterns in the bacteria that may help doctors choose better treatments.
Guangzhou, GuangdongAges 18–75 - NCT07148830Recruiting
Surgery technique study for pancreatic cancer patients
This trial tests a specific surgical method called mesopancreatic excision during Whipple surgery for pancreatic cancer. It may help remove more cancer tissue and improve outcomes for patients with resectable disease.
Minya, Minya GovernorateAges 18–75 - NCT07153692Recruiting
Brain stimulation for swallowing problems in Parkinson's
This study is testing whether a gentle brain-stimulation technique called tDCS can help people with Parkinson's disease who have trouble swallowing. If you have Parkinson's, multiple system atrophy, or progressive supranuclear palsy and a swallowing problem, this trial may be an option.
Hangzhou, ZhejiangAges 18–100 - NCT07148739RecruitingPhase 4
