[Daytime flexible application of Insulin degludec in patients with type 1 diabetes or type 2 diabetes]. / Tageszeitlich flexible Gabe von Insulin degludec bei Patienten mit Typ-1-Diabetes oderTyp-2-Diabetes.

ABSTRACT

BACKGROUND: Insulin degludec (IDeg) is a basal insulin with a stable, flat action profile and an even distribution of the blood glucose lowering effect over 24 hou rs. The terminal half-life of IDeg is about 25 hours, which reflects a mean prolongation by factor 2 compared to Insulin glargin (lGlar).This may enable for a more flexible daytime dosing versus up to now available basal insulins. METHOD: Two open, randomized, treat-to-target studies enrolled patients with type 1 diabetes (n =493) or type 2 diabetes (n = 687). Both phase 3 studies compared a daytime flexible dosing of IDeg (IDeg-flex) with IDeg at the evening meal (IDeg-evening) and IDler at a fixed daytime. In the IDeg-flex-group dosing intervals were predefined with variations between 8 and 40 hours. RESULTS: In patients with type 1 diabetes IDeg-flex proved to be non-inferior with respect to reduction of HbA1C (-0.40%) versus IDeg-evening (-0.41%) and IGlar (-0.58%) after 26 weeks. In addition, nocturnal hypoglycemic events were reduced by 40% (p < 0.01) with IDeg-flex versus IGlar. In patients with type 2 diabetes reduction of HbA1C with ID)eg-flex (-1.28%) was non-inferior to IDeg-evening (-1.07%) and IGlar (-1.26%), respectively, whereas rates for hypoglycemia were comparable. CONCLUSION: Patients with diabetes mellitus are enabled to dose a basal insulin flexibly when needed (minimum interval of 8 hours afterthe last injection is necessary). Impacts of this treatment option on quality of life and adherence and outcomes should be examined in observational trials.
