RESUMO
AIMS: This study aimed to evaluate the value and affordability of insulin glargine 300 U/mL (Gla-300) in a budget impact model from a United States (U.S.) payer perspective by leveraging recent real-world evidence (RWE) studies and incorporating the recent insulin price caps where applicable. MATERIALS AND METHODS: An economic model for a hypothetical one million U.S. health-plan population was developed to assess the budgetary impact of therapeutic interchanges in either direction between the two long- and longer-acting basal insulins (BIs) for patients with type 2 diabetes over a three-year model horizon. The utilization of long-acting BIs, longer-acting BIs, biosimilar BIs, and insulin degludec (IDeg-100) were informed by IQVIA data and internal forecasting at Sanofi. The DELIVER-2 and DELIVER-naïve studies provided healthcare resource utilization (HCRU) parameters. In the model base case, 24% of patients switched from long-acting BIs to insulin glargine biosimilars, IDeg-100, and other longer-acting BIs (Gla-300) by projected year 3. RESULTS: The base case total costs were $10,145 per patient per year (PPPY) in year 3 for the cumulative population. When all patients switched to Gla-300, the total costs in year 3 were $8,799, reflecting a net savings of -$660 PPPY compared to the budget increase of $686 PPPY in the base case. However, the longer-acting to long-acting BIs reversal scenario demonstrated a budgetary decrease of $676 PPPY over the model horizon. The reduction in incremental PPPY cost of $93 was observed using net drug costs rather than wholesale acquisition costs (WAC). LIMITATIONS: The market shares for years 1-3 were based on expectations supported by the clinicians' expert opinions and were not obtained from real-world data. CONCLUSIONS: The economic value of increased utilization of Gla-300 was driven by the reduction in HCRU, costs and market shares assumptions. Budgetary reductions were achieved by switching patients from long-acting BIs to Gla-300.
Type 2 Diabetes (T2D) is a chronic and debilitating condition that can lead to severe macro or microvascular complications. To mitigate these complications, it is crucial to effectively manage blood glucose levels. When other treatments prove ineffective in achieving adequate glucose control, insulin-based therapy becomes necessary. However, insulin-based treatments often come with the risk of hypoglycemic episodes, which can lead to increased utilization of healthcare resources (HCRU) and have a negative impact on costs.This study aimed to assess the budgetary impact of higher market shares of longer-acting basal insulins (specifically insulin glargine Gla-300) compared to long-acting basal insulins, insulin glargine biosimilars, and insulin degludec (IDeg) in the treatment of T2D. The perspective taken was that of a U.S. payer, taking into account the recent insulin price caps where applicable.The economic benefit of increased utilization of Gla-300 was driven by reductions in HCRU, costs, and market share assumptions. This resulted in a budgetary increase of $686 per patient per year (PPPY). In an alternative scenario where all patients transitioned to Gla-300, it led to a net savings of $660 PPPY.These findings provide valuable insights for decision-makers and healthcare professionals when making choices related to formulary placement and treatment utilization.
