Inducing Remission in Type 1 Diabetes with Alefacept (T1DAL)


The purpose of this trial is to test whether a drug called alefacept will slow or halt destruction of the beta cells in the pancreas. If the destruction of the beta cells is stopped the patients might be able to produce insulin on their own longer which could stop or slow the progression of their type 1 diabetes.

This proposal is for a multi-center prospective, placebo-controlled, double-blind and randomized, controlled trial to investigate the ability of alefacept to protect residual beta cells in adolescents and young adults with newly diagnosed Type 1 diabetes mellitus from ongoing autoimmune destruction.
