Abstract

Introduction: The aim of this study was to evaluate the short-term cost-utility of insulin degludec (degludec) versus insulin glargine 100 units/mL (glargine U100) for the treatment of type 2 diabetes in the basal–bolus subgroup of the head-to-head cardiovascular (CV) outcome trial, DEVOTE. Methods: A cost-utility analysis was conducted over a 2-year time horizon using a decision analytic model to compare costs in patients receiving once daily degludec or glargine U100, both as part of a basal–bolus regimen, in addition to standard care. Clinical outcomes and patient characteristics were taken exclusively from DEVOTE, whilst health-related quality of life utilities and UK-specific costs (expressed in 2016 GBP) were obtained from the literature. The analysis was conducted from the perspective of the National Health Service. Results: Degludec was associated with mean cost savings of GBP 28.78 per patient relative to glargine U100 in patients with type 2 diabetes at high CV risk. Cost savings were driven by the reduction in risk of diabetes-related complications with degludec, which offset the higher treatment costs relative to glargine U100. Degludec was associated with a mean improvement of 0.0064 quality-adjusted life-years (QALYs) compared with glargine U100, with improvements driven predominantly by lower rates of severe hypoglycemia with degludec versus glargine U100. Improvements in quality-adjusted life expectancy combined with cost neutrality resulted in degludec being dominant over glargine U100. Sensitivity analyses demonstrated that the incremental cost-utility ratio was stable to variations in the majority of model inputs. Conclusion: The present short-term modeling analysis found that for the basal–bolus subgroup of patients in DEVOTE, with a high risk of CV events, degludec was cost neutral (no additional costs) compared with glargine U100 over a 2-year time horizon in the UK setting. Furthermore, there were QALY gains with degludec, particularly due to the reduction in the risk of severe hypoglycemia. Funding: Novo Nordisk A/S.
