A retrospective, observational study was conducted to assess outcomes in patients with type 2 diabetes treated with second-generation basal insulin analogs.

Patients with type 2 diabetes mellitus who switched from first-generation to second-generation basal insulin analogs, either insulin glargine 300 units/mL or insulin degludec, showed comparable improvement in glycemic control, according to a study recently published in Diabetes, Obesity and Metabolism.

This retrospective study (DELIVER D+) compared the incidence of glycated hemoglobin (HbA1c) reduction, HbA1c goal attainment, and hypoglycemia between adults with type 2 diabetes switching from insulin glargine 100 units/mL to insulin glargine 300 units/mL (n=1592) and from insulin detemir to insulin degludec (n=1592). The study analyzed 5 subpopulations: patients taking basal and prandial insulins, patients with moderate to severe renal impairment, patients with a baseline HbA1c ≥8.0%, patients at high risk for hypoglycemia, and patients >65 years of age. 

Both basal insulin analogs had similar HbA1c reductions and goal attainments. Insulin glargine did show a significant reduction in hypoglycemic events from baseline to 6 months. These results were stable among all 5 subpopulations.

The researchers concluded “that switching from a first-generation ([insulin glargine 100 units/mL or insulin detemir]) to a second-generation ([insulin glargine 300 units/mL or insulin degludec]) basal insulin analogue resulted in post-switch improvements in glycaemic control and hypoglycemia incidence.”

This study was supported by Sanofi.
