Efficacy and Tolerability Study of Natura-Alpha in the Treatment of Patients With Active Ulcerative Colitis

Status unconfirmed · Phase 2 · Has a placebo group

Conditions studied: Ulcerative Colitis

In brief

This study is to evaluate the efficacy and tolerability of multiple oral doses of Natura-alpha capsule administered to patients with active ulcerative colitis. This will be a randomized, double-blind, placebo-controlled, parallel-design study. Up to 75 patients will complete this study (20 to 25 patients per treatment group) at approximately 10-12 clinical sites in the Unites States. Patients will be assigned at a 1:1:1 ratio to receive placebo, Natura-alpha 10 mg or Natura-alpha 20 mg, b.i.d. Replacement patients may be added, pending Sponsor approval, if it appears that less than 60 patients will complete the study.
