Abstract

Background and Aims: Patients with ulcerative colitis [UC] require rapid and complete relief of symptoms, particularly stool frequency and rectal bleeding. The aim of this study was to determine time to symptom resolution in patients with UC during induction treatment with multimatrix mesalazine, and the proportion of patients remaining symptom-free and in endoscopic remission after 12 months of maintenance. Methods: A pooled analysis of 5 pivotal clinical trials, including >1300 patients, evaluating multimatrix mesalazine for treatment of mild-to-moderate active UC was conducted. Time to symptom resolution was defined as the period between first drug dosage date and first 3 consecutive days of induction therapy when the patient achieved a score of 0 [normal] on a modified UC Disease Activity Index for stool frequency and/or rectal bleeding. Results: Median [95% confidence interval] time to resolution of stool frequency was 52 (45-not estimable [NE]) days for placebo versus 38 [34-41] days for multimatrix mesalazine [combined dose groups, 2.4 or 4.8 g/day]; time to resolution of rectal bleeding was 35 [20-NE] days for placebo versus 15 [14-17] days for multimatrix mesalazine [combined dose groups]. Among those who achieved resolution of both stool frequency and rectal bleeding during induction, 67.4% maintained symptom scores of 0 at Month 12. No relationship was observed between rapidity of symptom resolution during induction treatment and achievement of endoscopic remission at Month 12. Conclusions: Induction with multimatrix mesalazine provided rapid and prolonged symptom resolution in addition to endoscopic remission at Month 12.
