In the international Pre-POINT study, published in the renowned scientific journal JAMA, DZD scientists at the Paul Langerhans Institute Dresden and the Helmholtz Zentrum München achieved a breakthrough in the prevention of type 1 diabetes together with researchers from Vienna, Bristol and Denver (USA): They completed the first step in development of an insulin vaccine successfully.

The study, a double-blind, placebo-controlled, dose-escalation, assessed the immune responses and adverse events associated with orally administered insulin in autoantibody-negative, genetically at-risk children. The immune response to insulin was measured as serum IgG and saliva IgA binding to insulin, and CD4+ T-cell proliferative responses to insulin. In this pilot study of children at high risk for type 1 diabetes, daily oral administration of 67.5 mg of insulin, compared with placebo, resulted in an immune response without hypoglycemia. These findings support the need for a phase 3 trial to determine whether oral insulin can prevent islet autoimmunity and diabetes in such children.
