Abstract
Reducing the workload of the beta cell by inhibiting insulin secretion may provide
beneficial effects for patients with type 2 diabetes. The aim of this study was to
investigate the effect of NN414, a beta cell selective potassium channel opener in
patients with type 2 diabetes. 24 patients were treated for seven days (placebo, 1.5,
4.5, and 10 mg/kg). In accordance with the pharmacological profile a significant and
selective inhibition of insulin secretion was observed (1 h post dose). There were
no statistically significant effects on overall glycaemic control. Based on OGTT derived
parameters a borderline significant improvement in beta-cell function (1st and 2nd
phase insulin secretion) was observed from Day 1 to Day 7.
