Objectives: The glucagon-like peptide-1 agonist semaglutide and the dual glucose-dependent insulinotropic polypeptide tirzepatide have proven to significantly reduce glucose levels in people with type 2 diabetes. However, the costs needed to achieve a sustained decrease in HbA1c level and disease control with semaglutide and tirzepatide, respectively, are unclear. Therefore, this study aimed to compare the cost of treatment with semaglutide with the cost of treatment with tirzepatide for type 2 diabetes in Austria, the Netherlands, Lithuania, and the United Arab Emirates in order to determine their respective value for money.
Methods: The primary outcome of this analysis was the cost in euros needed to achieve disease control in one person with type 2 diabetes based on the composite endpoint of HbA1c <7%, ≥5% weight loss, and no hypoglycemic events. In addition, analyses regarding the cost needed to reach relevant HbA1c endpoints were performed. Clinical data were obtained from the SURPASS 2 trial, registered at clinicaltrials.gov (NCT03987919), and drug cost was based on wholesale acquisition cost or pharmacy purchase prices from public domains obtained in Q1 of 2023.
Results: The cost needed to achieve disease control in one person with type 2 diabetes (HbA1c <7%, ≥5% weight loss, and no hypoglycemic events) was up to three times lower using semaglutide compared with all three doses of tirzepatide in most markets. In the HbA1c analyses, semaglutide was also found to be the least expensive treatment option.
Conclusion: Semaglutide provides better value for money than tirzepatide for HbA1c-lowering endpoints.
