Celgene GED-0301 Phase III for Subjects With Crohn's Disease


Study Name

A Phase III, Randomized, Double-Blind, Placebo-Controlled, Multi-Center Study to Investigate the Efficacy and Safety of Mongersen (GED-0301) for the Treatment of Subjects With Active Crohn's Disease (IRB no. 43510)


Phase III


The purpose of this study is to evaluate the effects of an investigational drug called GED-0301 and to determine whether it can improve the symptoms of Crohn’s disease. Researchers will examine two doses of GED-0301 compared to placebo (inactive substance) and will assess how well the drug is tolerated. Researchers will also administer biomarker tests. Biomarkers are substances naturally occurring in the body, such as proteins, that indicate how the study drug is working.
