ABSTRACT
AIM: This study investigated the financial impact of introducing the once-daily single-inhaler triple therapy (SITT) fluticasone furoate/umeclidinium/vilanterol (FF/UMEC/VI) in Saudi Arabia for adult patients with uncontrolled asthma.
METHODS: The expected 5-year budget impact of introducing FF/UMEC/VI for asthma was modeled using an epidemiology-based approach that included both acquisition and efficacy-related costs. Year-on-year costs were estimated for 2026 through 2030. Changes in healthcare resource utilization after FF/UMEC/VI introduction were estimated from the expected change in asthma control reported in the Phase IIIa CAPTAIN trial. The perspective of the model was the Saudi national healthcare payer; only direct medical costs were included. The robustness of the model was tested using sensitivity and scenario analyses.
RESULTS: It was estimated that in 2026, 12,108 patients in Saudi Arabia would receive FF/UMEC/VI, which will likely increase over subsequent years (2027: 29,615 patients; 2028: 31,191 patients; 2029: 32,938 patients; 2030: 34,727 patients), as validated by local expert opinion. The introduction of FF/UMEC/VI was estimated to save a total of United States Dollars (USD) 10,654,389 over 5 years, or USD 16.32 per patient, with savings increasing each year after introduction. Drug acquisition costs contributed to the greatest impact on the budget, and the model was most sensitive to changes in the market uptake of FF/UMEC/VI. Across all sensitivity and scenario analyses, FF/UMEC/VI was consistently cost saving.
LIMITATIONS: Various model inputs could not be derived from published sources, so multiple assumptions were used. Future market share was estimated from current competitor market share data; as FF/UMEC/VI is the first SITT for asthma to be introduced into Saudi Arabia, there is no historical data on which to base these estimates.
CONCLUSION: Introducing FF/UMEC/VI in Saudi Arabia has the potential to deliver meaningful clinical and economic benefits at both the individual patient and healthcare system level.
