Efficacy and Safety Study of DiaPep277 in Newly Diagnosed Type 1 Diabetes Adults - Full Text View

Purpose

This study will look at the treatment effect of DiaPep277 on preservation of beta-cell function, as defined by meal-stimulated secretion of insulin. DiaPep277 is a peptide that changes the way the immune system behaves, stopping its attack on the beta-cells.

Adults (>20 years) with newly diagnosed (<6 months) type 1 diabetes will be treated with 10 injections of DiaPep277 or Placebo over a 2-year treatment and follow-up period.
