The glucokinase activator AZD6370 decreases fasting and postprandial glucose in type 2 diabetes mellitus patients with effects influenced by dosing regimen and food

Abstract

Aims: To investigate the pharmacodynamics, pharmacokinetics and safety of the glucokinase activator AZD6370 after 1 day of administration under fed and fasted conditions in patients with type 2 diabetes mellitus (T2DM).

Methods: This was a two-part study. In Part A, patients received a single oral dose of AZD6370 (20, 60 or 180 mg) or placebo in the fasted or fed states (both n=8). In Part B, patients (n=8) received placebo and a total dose of AZD6370 180 mg given in one, two or four divided doses. Plasma glucose, insulin and C-peptide changes versus placebo were assessed.

Results: AZD6370 provided dose-dependent reductions in plasma glucose of up to 30% versus placebo in both fasted and fed patients (p<0.001 at 60 and 180 mg doses). Insulin secretion increased with dose, but absolute increases were relatively small in the fasted versus fed state (0-4 h). Dosing AZD6370 twice or four-times over 1 day gave a smoother 24-h glucose profile than single-dose. AZD6370 was rapidly absorbed. Pharmacokinetics of AZD6370 were dose-independent and unaffected by food. AZD6370 was generally well tolerated.

Conclusions: AZD6370 produced dose-dependent glucose reductions and increased glucose-stimulated insulin secretion in patients with T2DM.
