Insulin Lispro with Continuous Subcutaneous Insulin Infusion is Safe and Effective in Patients with Type 2 Diabetes: A Randomized Crossover Trial of Insulin Lispro Versus Insulin Aspart

Objective: This study provides clinical information regarding the use of insulin lispro versus insulin aspart in continuous subcutaneous insulin infusion (CSII) in adult patients with type 2 diabetes mellitus (T2D).Methods: After a 2-week lead-in period, 122 subjects treated with CSII therapy were randomized to 32 weeks of treatment during 2 separate 16-week treatment periods (TPs) with crossover beginning with insulin lispro (n = 60) or insulin aspart (n = 62). Glycated hemoglobin A1c (HbA1c), total daily insulin dose, and weight were recorded at the end of TP1 and TP2. Adverse events (AEs) and hypoglycemic events (overall, documented symptomatic, nocturnal, or severe) were recorded throughout the TPs. Data were analyzed using statistical methods that accounted for repeated measurements.Results: A total of 107 subjects completed the study; 7 discontinued in TP1 and 8 discontinued in TP2. Insulin lispro was noninferior to insulin aspart in endpoint (weeks 16 and 32) HbA1c over TP1 and TP2 combined. Total ...
