RESUMEN
AIMS: To compare HbA1c and hypoglycaemia in insulin-naïve patients with type 2 diabetes (T2D) who initiated insulin glargine 300 units/mL (Gla-300) or 100 units/mL (Gla-100). MATERIALS AND METHODS: This retrospective cohort study examined electronic medical records of insulin-naïve adults with T2D who initiated Gla-300 or Gla-100 during March 2015 through to December 2016 with active records for ≥12 months before and ≥6 months after initiation, and ≥1 valid HbA1c value during 6-month baseline and 90-180-day follow-up. Outcomes included HbA1c and hypoglycaemia. Cohorts were propensity score-matched (1:2) on baseline demographic and clinical characteristics. Sensitivity analyses were conducted using broader inclusion criteria. RESULTS: The matched cohorts included 1004 Gla-300 and 2008 Gla-100 initiators (mean age 60.4 years; 53.2% male). During 6-month follow-up, Gla-300 versus Gla-100 initiators had a greater mean HbA1c decrease (-1.52 ± 2.08% vs. -1.30 ± 2.12%; P = 0.003) and more patients achieved HbA1c <7% (25.0% vs. 21.5%; P = 0.029) and <8% (55.0% vs. 49.2%; P = 0.002); and HbA1c <7% (21.9% vs. 17.4%; P = 0.003) and <8% (49.1% vs. 41.8%; P < 0.001) without hypoglycaemia. Gla-300 initiators were similarly or less likely to have any or inpatient/emergency department-associated hypoglycaemia during 3- and 6-month follow-up (e.g. any hypoglycaemia to 6 months: 9.7% vs. 12.5%; adjusted odds ratio 0.61; P = 0.057). CONCLUSIONS: Among insulin-naïve adults with T2D, Gla-300 was associated with significantly better HbA1c reductions (latest value during 90-180-day follow-up) and similar or improved hypoglycaemia outcomes (3- and 6-month follow-up) than Gla-100.

This retrospective cohort study compared real-world clinical and healthcare-resource utilization (HCRU) data in patients with type 2 diabetes using basal insulin (BI) who switched to insulin glargine 300 units/mL (Gla-300) or another BI. Data from the Predictive Health Intelligence Environment database 12 months before (baseline) and 6 months after (follow-up) the switch date (index date, March 1, 2015 to May 31, 2016) included glycated haemoglobin A1c (HbA1c), hypoglycaemia, HCRU and associated costs. Baseline characteristics were balanced using propensity score matching. Change in HbA1c from baseline was similar in both matched cohorts (n = 1819 in each). Hypoglycaemia incidence and adjusted event rate were significantly lower with Gla-300. Patients switching to Gla-300 had a significantly lower incidence of HCRU related to hypoglycaemia. All-cause and diabetes-related hospitalization and emergency-department HCRU were also favourable for Gla-300. Lower HCRU translated to lower costs in patients using Gla-300. In this real-world study, switching to Gla-300 reduced the risk of hypoglycaemia in patients with type 2 diabetes when compared with those switching to another BI, resulting in less HCRU and potential savings of associated costs.
