Brief Summary:
This is a randomized, double-blind, placebo-controlled, multicenter, and proof of concept study with a parallel group design to evaluate the safety and efficacy of oral Trichuris Suis Ova (TSO) suspension, as compared to placebo, in patients with moderately to severely active Crohn's disease. This study will also have an optional open-label extension for patients completing the double-blind phase of the study.
