Peripherally delivered hepatopreferential insulin analog insulin‐406 mimics the hypoglycaemia‐sparing effect of portal vein human insulin infusion in dogs

Aims We previously quantified the hypoglycaemia‐sparing effect of portal vs peripheral human insulin delivery. The current investigation aimed to determine whether a bioequivalent peripheral vein infusion of a hepatopreferential insulin analog, insulin‐406, could similarly protect against hypoglycae...

description Aims We previously quantified the hypoglycaemia‐sparing effect of portal vs peripheral human insulin delivery. The current investigation aimed to determine whether a bioequivalent peripheral vein infusion of a hepatopreferential insulin analog, insulin‐406, could similarly protect against hypoglycaemia. Materials and methods Dogs received human insulin infusions into either the hepatic portal vein (PoHI, n = 7) or a peripheral vein (PeHI, n = 7) for 180 minutes at four‐fold the basal secretion rate (6.6 pmol/kg/min) in a previous study. Insulin‐406 (Pe406, n = 7) was peripherally infused at 6.0 pmol/kg/min, a rate determined to decrease plasma glucose by the same amount as with PoHI infusion during the first 60 minutes. Glucagon was fixed at basal concentrations, mimicking the diminished α‐cell response seen in type 1 diabetes. Results Glucose dropped quickly with PeHI infusion, reaching 41 ± 3 mg/dL at 60 minutes, but more slowly with PoHI and Pe406 infusion (67 ± 2 and 72 ± 4 mg/dL, respectively; P
