Objective To compare the cost-utility of the glucagon-like peptide-1 receptor agonist albiglutide with those of insulin lispro (both in combination with insulin glargine), insulin glargine, and the dipeptidyl peptidase-4 inhibitor sitagliptin, representing treatments along the type 2 diabetes treatment continuum. Methods The Centre for Outcomes Research and Effectiveness (CORE) Diabetes Model was used for the cost-utility analysis. Data from three Phase 3 clinical trials (HARMONY 6, HARMONY 4, and HARMONY 3) evaluating albiglutide for the treatment of patients with type 2 diabetes were used for the baseline characteristics and treatment effects. Utilities and costs were derived from published sources. Results Albiglutide treatment was associated with an improvement in mean quality-adjusted life expectancy of 0.099, 0.033, and 0.101 years when compared with insulin lispro, insulin glargine, and sitagliptin, respectively. Over the 50-year time horizon, mean total costs in the albiglutide arm were $4332, $2597, and $2223 more than in the other respective treatments. These costs resulted in an incremental cost-utility ratio of $43,541, $79,166, and $22,094 per quality-adjusted life-year (QALY) gained for albiglutide vs insulin lispro, insulin glargine, and sitagliptin, respectively. At a willingness-to-pay threshold of $50,000 per QALY gained, there was a 53.0%, 41.5%, and 67.5% probability of albiglutide being cost-effective compared with the other respective treatments. Limitations This analysis was an extrapolation over a 50-year time horizon based on relatively short-term data obtained during clinical trials. It does not take into account potential differences between the respective treatments in adherence and persistence that can influence both effects and costs. Conclusions Albiglutide represents a reasonable treatment option for patients with type 2 diabetes based on its cost-utility, relative to insulin lispro, insulin glargine, and sitagliptin.
