SuonoBio - Evaluation of Ultrasound with Mesalazine Enema in Healthy Participants

Ulcerative colitis

Healthy participants who are undergoing a routine colonoscopy are invited to take part in this research project. The study is testing a potential new treatment for patients with ulcerative colitis, a chronic inflammatory bowel disease. The investigational product is called Suono 1 System and involves application of ultrasound to the rectum in combination with an approved enema containing the medication mesalazine.

The primary aim of study is to assess the safety and tolerability of treatment with the Suono 1 System.

The secondary aim is to measure availability of mesalazine in the colon following treatment with the investigational product.
