Dipeptidyl Peptidase-4 Inhibitors and Alpha-cell Recovery — DARE  

Type 1 Diabetes Clinical Trial

Official title: Effects of 6 Weeks Treatment With a Dipeptidyl Peptidase 4 Inhibitor on Counterregulatory and Incretin Hormones During Acute Hypoglycaemia in Patients With Type 1 Diabetes: a Randomized Double Blind Placebo-controlled Cross-over Study

Status Completed

Clinical Trial Summary

Hypoglycaemia is a well-known complication of insulin treated diabetes. The counterregulatory response to hypoglycaemia, with glucagon as the most important mediator, is initially diminished within a few years of onset of Type 1 diabetes and subsequently lost and thus increasing the risk of hypoglycaemia. Dipeptidyl Peptidase (DPP)-4 inhibitors augment the glucagon response to insulin-induced hypoglycaemia in type 2 diabetes. The investigators hypothesize that treatment with a DPP-4 inhibitor in patients with type 1 diabetes will recover the alpha cell response to hypoglycaemia.

Clinical Trial Description

The 16 type 1 patients will be randomised to one of two treatment sequences: DPP-4 inhibitor followed by placebo or placebo followed by a DPP-4 inhibitor. Each treatment period lasts 6 weeks, so all patients will receive treatment for 12 weeks in total. Induction of hypoglycaemia will take place at 0 weeks, 6 weeks and 12 weeks to determine the glucagon response. ;
