Brain-Gut Study of IBS with Anxiety and Depression
This study explores how stress and mood changes affect irritable bowel syndrome (IBS) using brain imaging. Researchers will scan your brain and collect health information to understand the connection between your gut and mental health.
Xi'an, ShaanxiAges 18–60 - NCT07649057Recruiting
Urine Test for Early Colorectal Cancer Detection
This study tests whether a simple urine sample can detect colorectal cancer or precancerous polyps. Researchers want to see if this non-invasive test could help identify people at risk before symptoms develop or catch cancer earlier.
New York, New YorkAges 18 years+ - NCT07649408Recruiting
How New Crohn's Treatments Affect Sleep Quality
This study looks at whether new biologic or targeted medications for Crohn's disease improve sleep quality. You would wear a watch while sleeping and answer questions about your sleep to help researchers understand if these advanced treatments help you sleep better.
Tel AvivAges 18 years+ - NCT07649928RecruitingEarly Phase 1
Testing ES502 for Advanced Pancreatic and Other Cancers
This early-stage trial tests a new drug called ES502 for patients with advanced cancers (including pancreatic cancer) that have a specific genetic mutation and certain immune markers. The study aims to find the right dose and see if it helps shrink tumors.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT07651358Recruiting
Web Program to Help Pancreatic Cancer Patients Exercise and Eat Better
This study tests a personalized website program called COMPASS designed to help people with stage I-III pancreatic cancer improve their exercise and diet while receiving chemotherapy before surgery. The goal is to see if this program helps patients feel better and stay stronger during treatment.
Portland, OregonAges 18 years+ - NCT07651553Recruiting
Transanal vs. Robotic Surgery for Rectal Cancer
This trial compares two surgical approaches to remove rectal cancer while preserving bowel function. Researchers want to see which method—performed through the anus or with robotic assistance—leads to better outcomes and quality of life.
Guangzhou, GuangdongAges 18–75 - NCT07651644Recruiting
AI tool to help doctors read gastric cancer imaging
This study tests whether an AI-assisted tool helps radiologists (doctors who read imaging scans) better interpret CT scans of gastric cancer patients. The research compares how accurately doctors read scans with and without AI help.
Shenyang, LiaoningAges Any age - NCT07652632Recruiting
Regenerative endoscopy for hard-to-treat Crohn's fistulas
This trial tests a new, less invasive procedure called regenerative endoscopy to repair complex fistulas in people with Crohn's disease. It's for those who haven't gotten better with standard treatments like biologics or surgery.
Hyderabad, TelanganaAges 18–65 - NCT07652892Recruiting
Fatty Liver, Memory, and Health in Men and Women
This study looks at how fatty liver disease (related to metabolism) affects memory, strength, and quality of life—especially comparing men and women. It helps understand why some people with fatty liver feel more tired or have trouble thinking clearly.

TAIC plus FOLFOX for advanced stomach cancer
This trial tests a traditional Chinese medicine (TAIC) combined with chemotherapy (FOLFOX) for people with advanced stomach or gastroesophageal junction cancer that can't be removed with surgery. It aims to see if the combination can help shrink the tumor and improve survival.
BeijingAges 18 years+ - NCT07656571Recruiting
