Brief Summary:

The primary purpose of this protocol is to assess the efficacy, tolerability, and safety of MGA031 when administered according to 3 different MGA031 dosing regimens in children and adults with recent-onset (diagnosis within past 12 weeks) type 1 diabetes mellitus. All regimens will be administered as an addition to insulin and other standard of care treatments. Efficacy will be defined primarily by the capacity of MGA031 to markedly reduce typical insulin requirements while maintaining relatively normal blood sugar levels.

Other studies involving the study drug use the name hOKT3γ1 (Ala-Ala). MGA031, a humanized monoclonal antibody, is the name used for hOKT3γ1 (Ala-Ala) that is produced by MacroGenics, Inc. The United States Adopted Name (USAN) for MGA031 is teplizumab.

    1. islet-cell autoantibodies (ICA512/IA-2),
    2. glutamic acid decarboxylase autoantibodies, or
    3. insulin autoantibodies (if present during first 2 weeks, but not beyond 2 weeks, of insulin treatment)
  6. Male or female

  8. Body weight ≥ 36 kg

Exclusion Criteria:

Subjects must have none of the following:

  1. Prior administration of a monoclonal antibody -- within the 1 year before enrollment or randomization at Study Day 0 -- that could potentially prevent or confound a therapeutic response to MGA031
