Posted on: 11 Oct 17

RHEINFELDEN, Switzerland, Oct. 11, 2017 – Full results of the phase III clinical study investigating a high strength 1600 mg oral formulation of mesalazine for the treatment of mild to moderate ulcerative colitis (UC) have been published in the international journal Alimentary Pharmacology & Therapeutics.1 In Europe, up to three million people suffer from inflammatory bowel diseases, such as UC, which can strongly reduce their quality of life.2 The aim of the double-blinded trial, sponsored by Tillotts Pharma AG (“Tillotts”), was to compare the efficacy and safety of the 1600 mg tablet against 400 mg tablet mesalazine formulations. Full results show that the primary objective of the study was met.1


The trial, led by Prof. Geert D’Haens, University of Amsterdam, was conducted in more than 800 patients with mild to moderate active UC at almost 180 centres in Europe and Canada. This makes it the largest trial of mesalazine induction therapy performed to date.1 Patients were randomised to 3.2 g of oral mesalazine, administered as two 1600 mg tablets once-daily or four 400 mg tablets twice-daily. Investigators, central readers, and patients were unaware of treatment assignment.


“Tillotts is committed to innovation. We leverage our expertise in drug delivery and controlled-release formulation to help patients improve their quality of life,” says Thomas A. Tóth von Kiskér, CEO at Tillotts. “This trial underscores our continued commitment to offer patients a wide range of treatments for disorders of the digestive system. This is a milestone for Tillotts and I would like to thank all patients, physicians and nurses who participated in making it possible”.


This study was the first trial of high strength mesalazine using central reading and blinded endoscopic video assessment.1 This ensures strict adherence to trial inclusion criteria and an unbiased interpretation of endoscopic imaging.3,4 Such an independent review of imaging endpoints is now required by regulatory agencies and is considered to be indispensable for phase III UC trials.3


About UC

UC is an inflammatory bowel disease (IBD) that involves chronic inflammation of the lining of the large bowel. In Europe, up to three million people suffer from IBDs, such as UC, which can strongly reduce their quality of life. Unlike Crohn’s disease, which can occur anywhere along the digestive tract, UC only affects the colon and rectum. UC causes swelling of the intestinal wall, in addition to ulceration of the large intestine. Symptoms vary, but often include abdominal pain and diarrhoea. UC is a chronic debilitating disease that may lead to life-threatening complications.


About Prof. Geert D’Haens

Geert D’Haens is professor of gastroenterology at the Academic Medical Center at the University of Amsterdam, where he leads a group of more than 35 IBD researchers. He is one of the founders of ECCO, the European Crohn’s and Colitis Organization. Presently, he is also Director of European Operations of Robarts Clinical Trials and chairman of IOIBD, the international organization for study of IBD. He has authored more than 300 peer reviewed articles so far.
