OBJECTIVE: The objective of this study was to evaluate the long-term cost effectiveness of exenatide once weekly (ExQW) versus insulin glargine (IG) or liraglutide 1.2 mg (Lira1.2mg) for the treatment of adult patients with type 2 diabetes mellitus (T2DM) not adequately controlled on oral antidiabetic drug (OAD) therapy in Greece.
METHODS: The published and validated Cardiff Diabetes Model was used to project clinical and economic outcomes over a patient's lifetime. Clinical data were retrieved from a head-to-head clinical trial (DURATION 3) and a published network meta-analysis comparing ExQW with IG or Lira1.2mg, respectively. Following a Greek third-party payer perspective, direct medical costs related to drug acquisition, consumables, developed micro- and macrovascular complications, maintenance treatment, as well as treatment-related adverse events were considered. Cost and utility data were extracted from literature and publicly available official sources and assigned to model parameters to calculate total quality-adjusted life-years (QALYs) and total costs as well as incremental cost-effectiveness ratios (ICERs). Sensitivity analyses explored the impact of changes in input data.
RESULTS: Over a patient's lifetime, ExQW was associated with 0.458 or 0.039 incremental QALYs compared with IG or Lira1.2mg, respectively, at additional costs of €2061 or €110, respectively. The ICER for ExQW was €4499/QALY compared with IG and €2827/QALY compared with Lira1.2mg. Results were robust across various one-way and scenario analyses. At the defined willingness-to-pay threshold of €36,000/QALY, probabilistic sensitivity analysis showed that ExQW had a 100 or 88.2% probability of being cost effective relative to IG or Lira1.2mg, respectively.
CONCLUSIONS: ExQW was estimated to be cost effective relative to IG or Lira1.2mg for the treatment of T2DM in adults not adequately controlled on OAD therapy in Greece.
