DEFEND-I: Phase 3 Trial of Otelixizumnab

Young Adults With Newly Diagnosed Type I Diabetes Mellitus


What is the purpose of this research trial?

DEFEND is a Phase 3 clinical research study evaluating an investigational agent. In type 1 diabetes, beta cells - the cells that make insulin - are destroyed by the body's immune system. If this destruction could be slowed or stopped, the person could continue to make some of their own insulin. The purpose of this study is to find out if a single 8-day course of the investigational agent infusions leads to greater improvement in insulin secretion. DEFEND is a "placebo controlled study," meaning some participants will receive the investigational agent and some will receive an inactive substance (placebo). Two-thirds of the participants will receive the investigational agent and one-third will receive placebo. These study agents will be administered as an addition to insulin, diet, and other standard of care treatments.
