Tepilizumab-mzwv (Tzield) - CAM 905

Background

Teplizumab-mzwv is a CD3-directed monoclonal antibody indicated to delay the onset of Stage 3 Type 1 diabetes (T1D) in adults and pediatric patients aged 8 years and older with Stage 2 T1D. It binds CD3 on the surface of T lymphocytes. Teplizumab-mzwv may deactivate the T lymphocytes that attack pancreatic insulin-producing beta cells, while increasing the proportion of regulatory T lymphocytes that help moderate the immune response.   

Policy

The use of Tzield is MEDICALLY NECESSARY to delay the onset of Stage 3 Type 1 diabetes in pediatric and adult patients that meet the following criteria:

  • Patient is 8 years of age or older; and
  • Diagnosis of Stage 2 Type 1 diabetes confirmed by all of the following:
    • Presence of at least two of the following pancreatic islet autoantibodies:
      • Glutamic acid decarboxylase 65 (GAD) autoantibodies
      • Insulin autoantibody (IAA)
      • Insulinoma-associated antigen 2 autoantibody (IA-2A)
      • Zinc transporter 8 autoantibody (ZnT8A)
      • Islet cell autoantibody (ICA)
    • Presence of dysglycemia without overt hyperglycemia defined by one of the following:
      • Fasting plasma glucose ≥ 100 mg/dL and < 126 mg/dL; or
      • 2-hour post-prandial plasma glucose level ≥ 140 mg/dL and < 200 mg/dL; or
      • A1C ≥ 5.7 and < 6.5% or ≥ 10% increase in A1C

AND

      • Patient does not have symptoms associated with Stage 3 Type 1 diabetes (e.g., increased urination, excessive thirst, weight loss); and
      • Diagnosis of Type 2 diabetes has been ruled out; and
    • Prescribed by or in consultation with an endocrinologist; and
    • Dosing is in accordance with the United States Food and Drug Administration approved labeling; and
    • Patient has not been previously treated with Tzield; and
    • Authorization will be issued for no more than one treatment course (i.e., 14 doses) per lifetime
