BACKGROUND: Multi-matrix (MMx), a new delivery system for mesalazine, seems to release 5-aminosalicyclic acid (5-ASA) preferentially in the sigmoid colon. This study had 2 objectives: (1) to evaluate the therapeutic response to MMx in patients with active left-sided disease and (2) to gain additional insights as to how the therapy would compare with topical 5-ASA. METHODS: Patients received either 1.2 g of 5-ASA MMx three times per day plus placebo enema or 4 g of 5-ASA enema plus placebo tablets for 8 weeks. The primary endpoint was clinical remission (clinical activity index < or =4) at 8 weeks. Secondary endpoints were endoscopic and histologic remissions. RESULTS: Seventy-nine patients were enrolled. Clinical remission rates at 4 and 8 weeks were 57.5% and 60.0% for patients treated with MMx and 68.4% and 50.0% for patients randomized to 5-ASA enemas, respectively (95% confidence interval for the difference at 8 weeks, -12 to +32). Endoscopic remission was achieved by 45.0% of patients on 5-ASA MMx and by 36.8% of those on enema, whereas 15.0% and 8% of patients, respectively, showed histologic remission. Compliance was 97.0% for oral and 87.5% for topical therapy. In the enema group, compliance was 88.0% for the patients in remission and 65.5% for those with active disease. CONCLUSIONS: Preliminary studies suggest that similar rates for induction of remission can be expected from 5-ASA enemas and MMx for patients with left-sided ulcerative colitis.
