Brief Summary:
The purpose of this study is to evaluate if immune-tolerance with Alum-formulated GAD (Diamyd), in combination with high dose Vitamin D3, may delay or stop the autoimmune process leading to clinical type 1 diabetes in non-diabetic children with ongoing beta-cell autoimmunity as indicated by positive islet autoantibodies.

Condition or disease Intervention/treatment Phase
Diabetes Mellitus, Type 1 Prediabetic State Drug: Alum-GAD Drug: Vitamin D3 Phase 2

Detailed Description:

The primary objective of this study is to evaluate if immune-tolerance with Alum-formulated GAD (Diamyd), combined with high dose Vitamin D3, may delay or stop the autoimmune process leading to clinical type 1 diabetes (diagnosed according to American Diabetes Association criteria) in non-diabetic 4-17.99 year old children with ongoing beta-cell autoimmunity as indicated by positive islet autoantibodies.

The secondary objective is to demonstrate that treatment with Diamyd is safe in children at risk for type 1 diabetes.

The children will be followed for 5 years in the study. Primary endpoint is proportion of subjects diagnosed with type 1 diabetes in each treatment arm. Secondary endpoints are 1) safety, 2) change in metabolic status from normal to impaired glucose metabolism in the group of children with normal glucose metabolism at baseline screening.

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Type 1 diabetes [ Time Frame: 5 years ]
    Proportion of subjects diagnosed with type 1 diabetes according to ADA criteria in each study arm


Secondary Outcome Measures :
  1. Impaired glucose metabolism [ Time Frame: During 5 year follow-up ]

    Change in metabolic status from normal to impaired glucose metabolism during follow-up in the group of children with normal glucose metabolism at baseline screening.

    Impaired glucose metabolism is defined as a) fasting plasma glucose 6.1 mmol/L or more, b) maximum plasma glucose 30, 60, 90 min during oral glucose tolerance test (OGTT) 11.1 mmol/L or more, c) 120 min plasma glucose on OGTT 7.8 mmol/L or more, d) HbA1c 39 mmol/L or more.


  2. Safety as measured by occurrence of adverse events [ Time Frame: 5 years follow-up ]
    Evaluation of safety of Diamyd and high dose Vitamin D3 in non-diabetic children as measured by occurrence of adverse events, injection site reactions, abnormal laboratory parameters or physical exam.
