Full Study Name

A Phase II Multi-Center, Randomized, Double-Blind, Placebo-Controlled, Parallel-Group Study to Evaluate the Efficacy and Safety of Induction Therapy with 2 Doses of TD-1473 in Subjects With Moderately to Severely Active Crohn's Disease (IRB no. 57123)


The purpose of this study is to evaluate the effectiveness of an investigational drug called TD-1473 in individuals with Crohn's disease. Specifically, the study will assess the safety and tolerability of TD-1473, as well as its effect on quality of life. Researchers will measure the way the body absorbs, distributes and gets rid of the study drug (pharmacokinetics), in addition to examining the effects of the drug on the human body (pharmacodynamics). The study will also explore whether the drug has any impact on Crohn's disease symptoms, disease severity and/or the levels of proteins or RNA (biologic products the body makes) that are associated with Crohn's disease.
