Glycaemic goal attainment and hypoglycaemia outcomes in type 2 diabetes patients initiating insulin glargine 300 units/mL or 100 units/mL: Real-world results from the DELIVER Naive cohort study.

ABSTRACT:

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.
