Abstract

Background and aims: Current treatments for Japanese patients with active Crohn's disease have not proved optimal, and new treatment options are required. The present study therefore evaluated the efficacy and tolerability of oral budesonide in Japanese patients with mild-to-moderate active Crohn's disease. Methods: In this multicentre, double-blind, randomized, parallel-group, Phase II study, patients (18-65. years) with baseline Crohn's Disease Activity Index (CDAI) score. ≥. 200 were randomized to once-daily (od) oral budesonide 9. mg or 15. mg, or matching placebo, for 8. weeks. Concomitant therapy with sulfasalazine or 5-aminosalicylic acid, and nutritional therapy, was allowed. The rate of remission (defined as CDAI score. ≤. 150) after 8. weeks' treatment (primary variable), health-related quality of life (assessed using the Inflammatory Bowel Disease Questionnaire [IBDQ]), and tolerability were assessed. Results: 77 patients were randomized and 63 completed the study. The proportion of budesonide-treated patients with remission after 8. weeks' treatment was higher compared with placebo (23.1%, 28.0%, and 11.5% for budesonide 9. mg, 15. mg, and placebo, respectively; no significant difference). The mean change from baseline to week 8 in CDAI total score (-. 48.0, -. 58.2, and -. 27.2, respectively) and IBDQ total score (10.8, 23.2, and 6.5, respectively) was greater for budesonide-treated patients than placebo recipients. While budesonide 9. mg and 15. mg demonstrated similar efficacy, budesonide 9. mg caused fewer drug- and glucocorticosteroid-related adverse events and less adrenal suppression. © 2012 European Crohn's and Colitis Organisation.
