Polyp

This study tests a vaccine that helps the body's immune system recognize and attack advanced colon polyps, which can turn into cancer. About 110 people who have had these polyps removed will receive either the vaccine or a placebo. The goal is to see if the vaccine boosts immune …

This study tests a nasal spray called OPN-375 in about 72 teenagers (ages 12-17) who have nasal polyps—growths inside the nose that cause stuffiness and breathing trouble. The spray is given twice a day for 16 weeks, and some participants receive a placebo (inactive spray) for co…

This study tests whether a bioelectric wound dressing can reduce infections after colon surgery better than the usual antiseptic skin prep. About 20 adults having elective colon surgery will be enrolled. Researchers will measure bacteria levels in skin samples to compare the two …

This study looks at whether ursodeoxycholic acid, a bile acid pill, can reduce the size of gallbladder polyps in 36 patients. The goal is to see if the treatment can help patients avoid surgery or frequent follow-up scans. Participants take the pill daily for at least six months,…

This study compares two methods for removing certain types of colon polyps (10-19mm adenomas or serrated lesions 10mm or larger) during a colonoscopy: cold snare piecemeal resection (CSPR) and cold snare endoscopic mucosal resection (Cold EMR). About 570 adults will take part to …

This study tests an investigational drug called 611 in 243 adults with chronic sinusitis and nasal polyps that haven't been well-controlled by other treatments. The goal is to see if 611 can shrink polyps and ease nasal congestion over 24 weeks. Participants receive either the dr…

This Phase 2 trial is testing dupilumab (Dupixent) in 17 people with aspirin-exacerbated respiratory disease (AERD), a condition that includes asthma, nasal polyps, and severe reactions to aspirin. The study aims to see if the drug can reduce markers of inflammation and improve s…

This study tests whether an artificial intelligence (AI) system can accurately identify the type of colon polyps during a colonoscopy, compared to standard visual inspection by the doctor. Over 1,700 adults having a colonoscopy will be randomly assigned to either AI-assisted or s…

This study tests a computer program that analyzes colonoscopy images to help doctors decide if a growth (polyp) is an adenoma (pre-cancerous) or not. The software gives a probability score for each lesion. The trial involves 1,178 adults and compares the software's results to lab…

This study tests a special probe that checks blood flow in ulcers left after colon polyp removal. The goal is to see if using this probe to guide treatment can prevent delayed bleeding, especially in patients taking blood thinners or with large polyps. About 180 high-risk adults …

This study tests whether rinsing the nose with a xylitol solution can reduce sinus symptoms in adults with cystic fibrosis. Participants will use both xylitol and standard saline rinses at different times to compare effects. The goal is to see if xylitol, a natural sugar alcohol,…

This pilot study tests whether a small procedure done in the doctor's office (called EPIC) can work as well as standard sinus surgery for people with chronic sinusitis and nasal polyps. The EPIC procedure is done under local anesthesia and has a shorter recovery time. The study o…

This study tests whether adding the anti-nausea drug ondansetron to a standard saline wash during gallbladder surgery can better control pain and nausea afterward. Forty adults having their gallbladder removed will be randomly assigned to receive either a plain saline wash or one…

This study tests a mechanical device that removes skin tags by cutting off their blood supply with a silicone band. It aims to be a less invasive option than freezing or burning. The study involves 200 adults with at least one skin tag between 4 and 6 millimeters wide.

This study tracks 80 adults with different smell disorders (like total loss, partial loss, or distorted smell) plus healthy volunteers over one year. Researchers use brain scans, smell tests, and questionnaires to see how the brain changes and how smell loss impacts mood and dail…

This study looks at whether a 6-month or 12-month follow-up colonoscopy is better for people who had a large colon polyp (20-50 mm) removed that was not cancerous. About 546 adults will be assigned to one of the two follow-up schedules. The goal is to see which timing finds any r…

This study looks at whether telling people over 45 their genetic risk for colorectal cancer helps them decide to get their first colonoscopy. Researchers will track how many people schedule a colonoscopy after learning their risk, and compare findings like polyps between risk gro…

This study follows 500 people who had a malignant colorectal polyp removed. Researchers want to learn how often the cancer stays, comes back, or spreads. They will also study how patients and doctors decide on next steps after removal. Participants share medical records and get f…

This study tests whether a two-week plant-based Mediterranean diet can change gut bacteria and reduce inflammation in people who have had colon polyps removed. Thirty participants will eat high-fiber meals delivered to their homes, and researchers will track changes in blood and …

This study follows 100 adults with severe chronic sinusitis and nasal polyps who are starting biologic treatments. Researchers want to see how these drugs improve quality of life, smell, and breathing over 6 months, and track any side effects. The goal is to learn which patients …

This study looks at whether a blood test that detects tumor DNA can accurately identify patients who still have cancer after local removal of early-stage colorectal cancer. Currently, many patients undergo additional surgery even though about 85% are already cured by the initial …

This study tracks 40 people with nasal polyps and severe asthma who are taking mepolizumab, a drug that reduces inflammation. Researchers collect nose, blood, and sputum samples before treatment and at 3, 6, and 12 months to see how the drug affects symptoms, nose bacteria, and g…

This study looks at whether a computer-aided diagnosis (CADx) system can help doctors better identify small colorectal polyps (5 mm or smaller) during a colonoscopy. Over 360 doctors will use the system to predict whether polyps are harmless or precancerous. The goal is to see if…

This study aimed to see if two advanced imaging modes, TXI and RDI, built into standard colonoscopy equipment, could make removing large colon polyps faster and safer. The trial was planned for adults with polyps 20 mm or larger, but it was withdrawn before any participants were …

This study is a national registry collecting data from 1500 people with familial adenomatous polyposis (FAP) and related conditions across 28 Italian centers. It aims to better understand how these diseases progress, how they are currently managed, and what factors influence outc…

This study follows 1,000 people with stomach pre-cancer conditions like chronic gastritis and intestinal metaplasia. Researchers will track disease progression over time and analyze biospecimens to find biomarkers linked to cancer development. The goal is to better understand who…
