Safety, Efficacy, and Tolerability Study of ASP3291 in Patients With Active Ulcerative Colitis

• Status: Completed
• Trial end date: 2014-04-01
• Target enrollment: 0
• Participant gender: All

Summary

This is a Phase 2, randomized, double-blind, multicenter, parallel, placebo controlled study. Approximately 120 eligible patients with mild-to-moderate active ulcerative colitis will be randomized to double blind treatment of either 1,000 mg twice daily (b.i.d.) ASP3291 (2,000 mg/d) or matching placebo in a 1:1 ratio for 8 weeks.

The study hypothesis is that treatment with ASP3291 compared to placebo will improve a patient's ulcerative colitis endoscopic score from baseline to Week 8.

• Phase: Phase 2
