Type 2 Diabetes Patients Reach Target Glycemic Control Faster Using IDegLira than Either Insulin Degludec or Liraglutide Given Alone

BACKGROUND AND OBJECTIVES: The time-course when changes in glycemic control and body weight were first manifest in patients with type 2 diabetes mellitus (T2DM) treated with a combination of insulin degludec and liraglutide (IDegLira) was assessed, comparing IDegLira to its individual components. METHODS: Data from weeks 0–12 from two studies were analyzed, one comparing IDegLira to each component (DUAL I), and one comparing IDegLira to insulin degludec titrated to a maximum 50 units (DUAL II). Efficacy endpoints included glycated hemoglobin (HbA(1c)) and fasting plasma glucose (FPG) reduction, proportion of patients achieving HbA(1c) [<7.0 % (<53.0 mmol/mol)] and FPG (≤7.2 mmol/L) targets, and proportion achieving HbA(1c) target without hypoglycemia and without hypoglycemia and weight gain. RESULTS: Mean HbA(1c) was lower, and the proportion of patients reaching target HbA(1c) greater, with IDegLira versus comparators (both studies) at weeks 8 and 12. Proportions of patients reaching target HbA(1c) without hypoglycemia and without hypoglycemia and weight gain were higher for IDegLira versus insulin degludec, though not versus liraglutide. Mean FPG was lower with IDegLira, and the proportion achieving target FPG higher, versus components (both studies) from weeks 4–12. IDegLira was associated with mean weight reduction from weeks 4–12, although less than with liraglutide alone. Hypoglycemia occurred infrequently in weeks 0–12, with no difference in incidence between IDegLira and insulin degludec in either study. CONCLUSIONS: IDegLira reduces plasma glucose to a greater extent than its components, measurable within the first 12 weeks of therapy, and without weight gain or an increased hypoglycemia risk versus insulin degludec.
