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.

Project description:IntroductionThis study investigated glycaemic control in individuals with type 1 (T1D) or type 2 diabetes (T2D) 6 months after initiating fast-acting insulin aspart (faster aspart) in a real-world setting.MethodsThis was a single-arm, observational study using extracted patient data from the IBM® Explorys® database (USA) for individuals with T1D or T2D initiating faster aspart (at least one prescription of faster aspart) in the study period 1 January 2018 to 27 October 2020. Clinical characteristics, including age, body mass index, and baseline HbA1c, were extracted, as well as recorded events of hypoglycaemia. The primary endpoint was the change in HbA1c from baseline to 6 months.ResultsA total of 787 individuals were included; 36.6% of these individuals had T1D and 63.4% had T2D (of whom 46.9% were new users of rapid-acting insulin when initiating faster aspart [T2D new users] and 53.1% were switching from another rapid-acting insulin to faster aspart [T2D switchers]). For individuals with T1D, T2D new users, or T2D switchers, estimated mean change in HbA1c from baseline to 6 months was - 0.20% (95% CI - 0.53, 0.14; p = 0.252), - 1.00% (95% CI - 1.34, - 0.67; p < 0.0001), and - 0.70% (95% CI - 1.06, - 0.35; p = 0.0001), respectively. In the baseline HbA1c > 8.5% subgroup, there was a significant estimated decrease in HbA1c from baseline to 6 months in individuals with T1D (- 1.2% [95% CI - 1.80, - 0.60]; p = 0.0001) or T2D (- 0.6% [95% CI - 0.92, - 0.35]; p < 0.0001). Event rates of hypoglycaemia after 12 months were 0.68, 0.38, and 0.59 events/year for individuals with T1D, T2D new users, and T2D switchers, respectively.ConclusionUS IBM® Explorys® data demonstrated a clinically relevant reduction in HbA1c 6 months after initiating faster aspart treatment for individuals with T2D, but not T1D overall, although patients with baseline HbA1c > 8.5% had significant HbA1c reductions regardless of diabetes type.

Project description:BACKGROUND:Fast-acting insulin aspart (faster aspart) is an ultra-fast-acting formulation of insulin aspart (IAsp). This post hoc analysis investigated the pharmacokinetics of faster aspart versus IAsp, measured as free or total IAsp, and the relationship between anti-IAsp antibodies and the pharmacokinetics/pharmacodynamics of faster aspart and IAsp. METHODS:Free and total IAsp concentrations and anti-IAsp antibodies were determined in adults with type 1 diabetes mellitus receiving subcutaneous faster aspart and/or IAsp in four single-dose clinical pharmacology trials (n = 175) and a 26-week phase IIIa trial (n = 1040). Pharmacodynamics were assessed by euglycaemic clamp or meal test, respectively. RESULTS:The pharmacokinetic profile was left-shifted and early exposure was greater with faster aspart versus IAsp independent of free or total IAsp assay. The faster aspart-IAsp difference in the time to 50% of maximum IAsp concentration in the early part of the pharmacokinetic profile (tEarly 50 % Cmax) [95% confidence interval (CI)] was - 8.8 [- 10.0 to - 7.5] and - 7.6 [- 8.8 to - 6.4] min for free and total IAsp, respectively. The faster aspart/IAsp ratio for the area under the concentration-time curve (AUC) for IAsp from time zero to 30 min (AUCIAsp,0-30 min) [95% CI] was 1.88 [1.74-2.04] and 1.77 [1.64-1.90] for free and total IAsp. Higher anti-IAsp antibody levels were associated with a lower ratio of free/total IAsp for the total AUC for IAsp (AUCIAsp,0-t). Early glucose-lowering effect (AUC for the glucose infusion rate [GIR] from time zero to 60 min [AUCGIR,0-60 min]) was greater by 25-44% for faster aspart versus IAsp independent of anti-IAsp antibody levels. Total glucose-lowering effect (total AUC for GIR [AUCGIR,0-t]) in a clamp and 1-h postprandial glucose increment in a meal test appeared essentially unaffected by anti-IAsp antibodies. CONCLUSIONS:Faster aspart provides accelerated pharmacokinetics versus IAsp regardless if based on free or total IAsp assay. Higher anti-IAsp antibodies increase total IAsp concentrations but do not influence faster aspart nor IAsp pharmacodynamics. CLINICALTRIALS.
