Summary Background 5‐ASA‐MMX ® (1.2 g/tablet) is a 5‐aminosalicylic acid formulation, designed for once‐daily dosing in the treatment of ulcerative colitis. Aim To evaluate the efficacy and safety of 5‐ASA‐MMX (2.4 g/day, once daily), compared with Asacol ® (2.4 g/day, twice daily) in the maintenance of left‐sided UC, through a double‐blind, double‐dummy, parallel‐group, randomized, comparator study. Methods In all, 331 patients with UC were randomized to receive either 5‐ASA‐MMX 2.4 g/day, once daily, or Asacol 2.4 g/day, twice daily, for 12 months. All patients were in remission for ≥1 month prior to the trial, with ≥1 documented relapse in the previous year. The co‐primary endpoints of this study were the proportion of patients in clinical, and clinical and endoscopic remission following 12 months’ treatment. Results In the intent‐to‐treat population, excluding those with major protocol deviations, 68.0 and 65.9% patients in the 5‐ASA‐MMX and Asacol groups, respectively, were in clinical remission ( P = 0.69), and 60.9 and 61.7% of patients, respectively, were in clinical and endoscopic remission ( P = 0.89). Diary card data revealed statistically significant treatment differences favouring 5‐ASA‐MMX. Both treatments were similarly tolerated. Conclusions Once‐daily 5‐ASA‐MMX is similarly effective with a comparable safety profile to Asacol administered twice daily, for the maintenance treatment of ulcerative colitis.
