- Abstract
- Background SPD476 (MMX (TM) mesalazine), is a novel, once daily, high-strength mesalazine formulation (1.2 g/tablet) that utilizes Multi Matrix System (TM) (MMX) technology to delay and extend delivery of the active drug throughout the colon. Aim To assess the safety and efficacy of MMX mesalazine in patients with mild-to-moderately active ulcerative colitis, in a pilot, phase II, randomized, multicentre, double-blind, parallel-group, dose-ranging study (SPD476-202). Methods Thirty-eight patients with mild-to-moderately active ulcerative colitis were randomized to MMX mesalazine 1.2, 2.4 or 4.8 g/day given once daily for 8 weeks. Remission ulcerative colitis-disease activity index (UC-DAI) <= 1, a score of 0 for rectal bleeding and stool frequency, and >= 1-point reduction in sigmoidoscopy score from baseline was the primary end point. Results Week 8 remission rates were 0%, 31% and 18% of patients receiving MMX mesalazine 1.2, 2.4 and 4.8 g/day respectively. No statistically significant difference in remission was observed between treatment groups. MMX mesalazine 2.4 and 4.8 g/day groups demonstrated greater improvement in overall UC-DAI and component scores from baseline, compared with the 1.2 g/day group. Conclusion MMX mesalazine given as 2.4 or 4.8 g/day once daily is well tolerated and effective for the treatment of mild-to-moderately active ulcerative colitis.
