Glycaemic control and hypoglycaemia in people with type 2 diabetes switching from twice-daily basal insulin to once-daily insulin glargine 300 U/mL or insulin glargine 100 U/mL (EDITION 1 and EDITION 2 subgroup analysis).

ABSTRACT: In this post hoc analysis we compared glycaemic control and hypoglycaemia between insulin glargine 300 U/mL (Gla-300) and glargine 100 U/mL (Gla-100) administered once daily in people with type 2 diabetes (T2DM) from the EDITION 1 (basal plus mealtime insulin) and EDITION 2 (basal insulin plus oral antihyperglycaemic drugs) trials who were previously receiving twice-daily insulin. At randomization, 16.9% and 20.0% of people in EDITION 1 and 2, respectively, were receiving twice-daily basal insulin. Glycated haemoglobin change from baseline to Month 6 was similar over 6 months with Gla-300 or Gla-100 (least squares mean difference -0.01%; 95% confidence interval [CI] -0.27 to 0.24] in EDITION 1 and 0.16%; 95% CI -0.25 to 0.57, in EDITION 2). Participants previously receiving twice-daily insulin in EDITION 1 had a lower risk of confirmed (?3.9 mmol/L [?70 mg/dL]) or severe hypoglycaemia with Gla-300 vs Gla-100 at night (00:00-05:59 hours), but not at any time (24 hours); in EDITION 2 the risk was reduced at night and any time (24 hours). In conclusion, Gla-300 provided similar glycaemic control with less hypoglycaemia compared with Gla-100 in people with T2DM switching from twice-daily to once-daily basal insulin.

Project description:INTRODUCTION:OPTIMIZE evaluated the efficacy, safety and treatment satisfaction of insulin glargine 300 U/mL once daily (Gla-300 OD) in people with type 1 diabetes mellitus (T1DM) previously uncontrolled on basal insulin twice daily (BID) as part of basal-bolus therapy. METHODS:OPTIMIZE was a 28-week, prospective, interventional, single-arm phase 4 trial in adults with T1DM. At baseline, basal insulin BID treatment was switched to Gla-300 OD titrated to a fasting self-monitored blood glucose target of 4.4-7.2 mmol/L (80-130 mg/dL). The primary endpoint was the mean glycated haemoglobin (HbA1c) change from baseline to week 24. Secondary endpoints included self-monitored blood glucose, fasting-plasma glucose, hypoglycaemia and patient-reported outcomes including the Diabetes Treatment Satisfaction Questionnaire status version (DTSQs). RESULTS:Switching to Gla-300 OD significantly improved mean HbA1c (8.54% at baseline and 8.27% at week 24 [last observation carried forward, N = 94, p < 0.0001]; mean difference 0.27% [95% CI 0.15, 0.40]). There was a statistically significant decrease in fasting self-monitored blood glucose during the study (analysis of variance for repeated measures, p = 0.014; N = 72). Eight-point self-monitored blood glucose was significantly improved between baseline and week 24 for post-breakfast (p = 0.009), post-dinner (p = 0.009) and bedtime (p = 0.049) values. The study did not allow for any significant effects on confirmed and/or severe hypoglycaemia at the ≤ 3.9 mmol/L [≤ 70 mg/dL] or < 3.0 mmol/L [< 54 mg/dL] blood glucose cut-offs to be observed. Statistically significant improvements were observed in DTSQs total scores from baseline (24.1) to week 24 (29.4, p < 0.0001). CONCLUSIONS:A basal-bolus regimen including Gla-300 OD was associated with improvements in HbA1c and treatment satisfaction in people with uncontrolled T1DM previously receiving basal-bolus insulin including a basal insulin BID analogue.
