NCT01439854

Brief Summary

The purpose of this study is to examine the effect of the chronic treatment of type 2 diabetes (T2DM) with dapagliflozin on: (1) mitochondrial gene function/expression and insulin signaling/action and (2) oral glucose tolerance and beta cell function. Dapagliflozin is a potent, highly specific inhibitor of renal glucose transport \[SGLT2\].

    baseline, two weeks

Secondary Outcomes (1)

  • Change in Mitochondrial Function

    baseline, two weeks
