Abstract:
Objective To introduce the design of a non-inferiority clinical trial for evaluating the mild-to-moderate active ulcerative coli-tis. Methods Based on international literature and the European guide-line on the development of new medicinal products for the treatment of ul-cerative colitis, a clinical trial was designed in involving with the positive control, non-inferiority margin, primary endpoint and the dose-finding within accepted efficacy and safety for a treatment of mild-to-moderate active ulcerative colitis. A real example of ulcerative colitis was intro-duced and its primary data were simulated for quantitative analysis. Re-sult For the non-inferiority clinical trial on mild-to-moderate active ulcerative colitis, the standard positive control should be aminosalicylic acid (5-ASA) with the dose of 3 g/day, the non-inferior margin is approximately 15%, and the CAI scale is recommended as primary end-point. Conclusion This study can provide some important information for similar clinical research.
