The present phase 3, randomized, open-label study compared the efficacy and safety of basal insulin peglispro with insulin glargine after 26 weeks of treatment when added to oral antihyperglycemic medications in insulin-naïve Asian patients with type 2 diabetes.

Materials and Methods

The primary objective was to show non-inferiority of the change in glycated hemoglobin from baseline to 26 weeks.


At 26 weeks, insulin peglispro was non-inferior to glargine, meeting the primary objective. Patients receiving insulin peglispro (n = 192) showed a greater reduction in glycated hemoglobin from baseline compared with glargine (n = 196); −1.6 vs −1.4%, P = 0.005) and in fasting serum glucose (−61.2 vs −54.8 mg/dL, P = 0.02). A significantly higher proportion of patients receiving insulin peglispro achieved glycated hemoglobin <7% (57 vs 44%, P = 0.012). Insulin peglispro patients showed significantly less weight gain from baseline (1.1 vs 1.6 kg, P = 0.03). Relative rates (insulin peglispro/glargine) of total and nocturnal hypoglycemia through 26 weeks were 1.06 (P = 0.67) and 0.7 (P = 0.10), respectively. Significantly more insulin peglispro-treated patients experienced adverse events compared with glargine-treated patients (P = 0.042). Alanine aminotransferase and aspartate aminotransferase were significantly increased from baseline with insulin peglispro compared with glargine at week 26 (3.5 vs −4.6 IU/L and 2.8 vs −1.5 IU/L, respectively; P < 0.001). The incidence of injection site reactions was low and did not differ between the treatments.


Insulin peglispro provided better glycemic control vs glargine with no differences in hypoglycemia and increased aminotransferases in insulin-naïve Asian patients with type 2 diabetes.
