Efficacy and Safety of Asacol™ 4.8 g/Day (800 mg Tablets) for the Treatment of Active Ulcerative Colitis

Phase 3

Completed

• Conditions: Ulcerative Colitis
• Interventions: Drug: Mesalamin

• Registration Number: NCT01059344
• Lead Sponsor: Tillotts Pharma AG

Brief Summary

The primary objective of the study is to determine the efficacy of Asacol™ 4.8 g/day (800 mg tablets) to induce clinical and endoscopic remission after 6 weeks of treatment compared to placebo in subjects with active ulcerative colitis (UC).

Detailed Description

The 800 mg Asacol™ tablets from Tillotts Pharma AG are being marketed in over 30 countries, mainly in Europe and Asia. Approved dosages for the treatment of active UC are between 2.4 and 4.8 g/day in analogy to the approved 400 mg dosage form. The present trial is planned to generate efficacy data to support the safe use of a 4.8 g/day dose of the 800 mg dosage form in a well defined population of patients with mildly to moderately active UC. In keeping with the EMEA UC guideline the study will have a placebo-controlled 6 weeks induction treatment. After 6 weeks, treatment success will be evaluated using the modified UC disease activity index as primary efficacy measurement.
