Mealtime fast-acting insulin aspart versus insulin aspart for controlling postprandial hyperglycaemia in people with insulin-resistant Type 2 diabetes.

ABSTRACT: AIM:This post hoc analysis explored whether mealtime fast-acting insulin aspart treatment provided an advantage in postprandial plasma glucose (PPG) control vs. insulin aspart in people with Type 2 diabetes receiving high doses of bolus insulin. METHODS:A post hoc, post-randomization, subgroup analysis of a 26-week, randomized, double-blind, treat-to-target trial (onset 2) that compared mealtime fast-acting insulin aspart vs. mealtime insulin aspart, both in a basal-bolus regimen, in people with Type 2 diabetes uncontrolled on basal insulin therapy and metformin. At the end of trial, the impact of fast-acting insulin aspart and insulin aspart on PPG control was assessed with a standard liquid meal test and participants were grouped into three post-randomization subgroups: meal test bolus insulin dose ? 10 units per dose (n = 171), > 10-20 units per dose (n = 289) and > 20 units per dose (n = 146). RESULTS:A statistically significant treatment difference in favour of fast-acting insulin aspart vs. insulin aspart was observed for the change in PPG increment at all post-meal time points (from 1 to 4 h) for those in the > 20 units bolus insulin subgroup. There was no difference in the magnitude of change from baseline in HbA1c level between fast-acting insulin aspart and insulin aspart in any of the bolus insulin dose subgroups (data herein). CONCLUSION:Fast-acting insulin aspart may hold promise as a more effective treatment compared with insulin aspart for controlling PPG in people with insulin-resistant Type 2 diabetes.
