This early-phase study tests a new treatment called KN5601, which uses specially engineered natural killer (NK) cells to target and destroy disease-causing immune cells in people with relapsed or refractory IgG4-related disease. The trial will enroll 18 adults and primarily check…

This study tests a new, non-surgical treatment called ERAT for mild appendicitis. Instead of removing the appendix, doctors use a flexible tube through the colon to clear the blockage and infection. The trial will compare ERAT to standard laparoscopic surgery in 376 adults to see…

This study tests whether treating an extra area in the heart (the superior vena cava) along with the standard treatment (pulmonary vein isolation) can better prevent irregular heartbeats in people with paroxysmal atrial fibrillation. About 650 adults aged 18-80 will be randomly a…

This study tests whether giving three drugs (epacadostat, lenvatinib, and standard chemotherapy) before surgery can completely eliminate esophageal cancer in 33 adults with stage II to IVa disease. The main goal is to see if no cancer remains in the removed tissue. Participants m…

This study looks at whether a special microscope on a thin probe (pCLE) can better detect early stomach cancer than the usual biopsy method. Researchers will review past cases from 169 patients who had both tests. The goal is to see which method is more sensitive and accurate, wh…

This study tests a new device that flattens colon polyps before they are examined under a microscope. The goal is to help doctors better identify sessile serrated lesions, a type of polyp that can lead to colorectal cancer. About 1,156 adults having polyps removed during a colono…

This study tests whether spraying a mix of acetic acid and indigo carmine dye during colonoscopy helps doctors find more precancerous polyps (called sessile serrated lesions) in the right side of the colon compared to standard white-light colonoscopy. About 2,689 adults aged 45-8…

This study looks back at medical records of 350 people who had a capsule endoscopy (swallowing a pill-sized camera) for gastrointestinal bleeding. Researchers want to see how often the camera finds the bleeding source and if any problems occur. No new tests or visits are needed—o…

This study compares a new balloon-assisted method to the standard water-injection technique for creating a bypass around a blocked stomach outlet. The blockage, often caused by advanced cancer, leads to nausea and malnutrition. The new device aims to shorten procedure time and re…

This study will follow 800 people, including those with chronic pancreatitis, pancreatic cancer, and healthy volunteers, to learn why some pancreatitis patients later get pancreatic cancer. Participants give blood samples and health info; some may also provide tissue samples. Res…
