Anti-diabetic Effects of Liraglutide in Adolescents and Young Subjects With Type 1 Diabetes
Study Details
Study Description
Brief Summary
This is the first prospective randomized double-blind placebo-controlled study to investigate the effect of a GLP-1 analog, specifically liraglutide, on blood glucose levels and variability in subjects with type 1 diabetes treated with insulin. Liraglutide is the preferred GLP-1 analog for this study because the pharmacokinetics and pharmacodynamics of the drug are consistent with a sustained duration of action. The current gold standard for management of type 1 diabetes is based on insulin replacement with novel analogs with specified pharmacodynamic profiles or with unique insulin delivery systems (insulin pump therapy). No other adjuvant therapy has demonstrated sustained benefit in this population. This study will also investigate the effect of liraglutide on suppression of glucagon secretion during meal challenges. This is of particular importance since, in the absence of insulin secretion from the β-cell, there is no paracrine inhibition of glucagon secretion by the α-cell. Dysregulation of glucagon secretion may impact the glycemic control and overall pathogenesis in those with type 1 diabetes. The use of CGM technology in this study will allow us to determine the rapidity, consistency, and sustainability of any response to liraglutide.

Outcome Measures
Primary Outcome Measures
- Mean weekly blood glucose concentrations. [3 Months]
The primary endpoint of the study is to detect a difference between Liraglutide and placebo groups in the change from baseline in mean weekly blood glucose concentrations after 12 weeks of treatment.
Secondary Outcome Measures
- HbA1c [3 Months]
Eligibility Criteria
Criteria
Inclusion Criteria:
- INCLUSION CRITERIA:
-
Females and males with Type 1 diabetes as ascertained by islet autoantibodies (GAD-65 and/or islet cell antibodies)
-
Age 15-30 years - This age group is being chosen as most will have completed puberty with the accompanying physiologic phase of increased insulin resistance. In addition, this age group shows increased self-management capabilities. Extending the age up to 30 years will allow us to include young adults, since type 1 diabetes is frequently diagnosed in the late teen and early adult years. This study is not powered to detect differences in liraglutide efficacy in different age group but it may provide insight into the effectiveness in the teenage population, in whom optimal glycemic control is often a challenge.
-
Type 1 diabetes duration greater than 1 year to ensure that a majority of subjects are beyond the partial remission period.
-
Fasting C-peptide level ≤ 0.3 ng/ml.
-
HbA1c level equal or less than 9%
-
Insulin delivery by CSII - the choice is made to facilitate adherence to study drug and also to enable us have a homogeneous group to analyze without having to analyze the data for the covariants of CSII vs. multiple daily injection therapy.
-
Subjects willing to wear a CGM sensor and perform home blood glucose monitoring four times daily and with symptoms of hypoglycemia.
-
Subjects well-versed in carbohydrate counting.
-
BMI < 95th% for age and gender.
