Primary outcomePrimary: the Relative Increase in Meal-induced Total GLP-1 Secretion — 2591; 3959 pM x 120 min

Summary

We wish to evaluate the effect of long term treatment with a DPP-IV inhibitor on the function of the incretin hormones Hypothesis We hypothesize that that a gradual improvement in metabolic control induced by DPP-IV inhibitor (Januvia®) treatment significantly ameliorates the impaired secretion and potency of GLP-1 and leads to a restoration of the lost action of GIP.
