  1. Time to initial resolution of rectal bleeding and high stool frequency in patients who achieved clinical and endoscopic remission after up to 8 weeks

  2. STUDY 303:Long-term Safety Data on Mesalamine for Patients with Ulcerative Colitis

  3. Objectives • Study design • Patient disposition • Definitions • Safety of 8-week acute extension • Efficacy of 8-week acute extension • Summary

  4. Mesalamine 2.4 and 4.8 g/day Is Effective for the Induction of Remission • Lichtenstein et al.1 and Kamm et al.2 studies: Two double-blind,placebo-controlled, phase III studies evaluating the efficacy and tolerability of mesalamine • Both studies demonstrated mesalamine 2.4 g/day (given q.d. or 1.2 g b.i.d.) and 4.8 g/day (given q.d.) to be efficacious and well tolerated for the induction of remission in patients with active, mild-to-moderate ulcerative colitis Adapted from: 1Lichtenstein et al. Clin Gastroenterol Hepatol 2007;5:95–102. 2Kamm et al. Gastroenterology 2007;132:66–75.

  5. Modified* UC-Disease Activity Index * Friability moved from Score of 1 to 2 Adapted from Kamm et al. Gastroenterology 2007;132:66–75.

  6. End Point Definitions • Relapse: Withdrawal from the study due to a requirement for alternative treatment (including a dose increase or surgery) for an exacerbation of UC • Remission: Modified UC-DAI score 1, calculated as a score of 0 for rectal bleeding and for stool frequency, a combined Physician’s Global Assessment (PGA) and sigmoidoscopy score of 1, no mucosal friability, and a sigmoidoscopy score reduction of 1 point or more from baseline Adapted from Kamm et al.2008;57(7):893-902.

  7. STUDY 303 Efficacy Results: 8-Week Acute Extension Phase

  8. Up to 8 weeks’ active treatment Up to 16 weeks’ active treatment (n = 107) (n = 78) (n = 78) (n = 41) Prior treatment

  9. 8-Week Acute Extension Phase:Sigmoidoscopy Scores Number of patients (%) *Week 0=First study visit of the acute extension phase • Adapted from Lichtenstein et al. Poster presented at ACG 2007.

  10. STUDY 303 Acute Extension Phase Conclusions1,2 • Mesalamine 4.8 g/day (2.4 g dosed b.i.d.) was well-tolerated in the 8-week acute extension phase • Safety profile similar to that of the parent studies (Lichtenstein et al. and Kamm et al.) • Mesalamine 4.8 g/day for up to 4 months was well-tolerated • Approximately 60% of patients achieved remission, using stringent clinical and endoscopic criteria Adapted from: 1Lichtenstein et al. Poster presented at APhA 2007.2 Lichtenstein et al. Poster presented at ACG 2007.
