NCT01922817

Brief Summary

A small, pilot, randomised, cross over trial that investigates the potential for DPPIVi therapy to reduce insulin requirements in type 1 diabetes was studied. We investigated whether this drug reduces daily insulin doses, leads to weight reduction, reduces blood glucose fluctuation and improves glucose control. Through reduction of blood glucose variability, we want investigated, whether it has the capability of improving the magnitude of epinephrine responses at 2.5mmol/L by performing a hyperinsulinaemic, hypoglycaemia clamp study after each arm. A successful outcome would then lead to an application for funds for a larger, multicentre intervention study. The benefits of this therapeutic advance are clear and this has the potential to make a dramatic improvement to the lives of people with type 1 diabetes in our community.
