AIMSEmpagliflozin confers cardioprotective benefits among patients with heart failure, across the range of ejection fraction (EF), regardless of type 2 diabetes status. The long-term cost-effectiveness of empagliflozin for the treatment of heart failure (HF) in the Philippines remains unclear. This study aims to determine the economic benefit of adding empagliflozin to the standard of care (SoC) vs the SoC alone for HF in the Philippines.METHODSUsing a Markov model, we predicted lifetime costs and clinical outcomes associated with treating HF in the Philippine setting. We used estimates of treatment efficacy, event probabilities, and derivations of utilities from the EMPEROR trials. Costs were derived from hospital tariffs and expert consensus. Separate analyses were performed for patients with left ventricular EF > 40%, categorized under mid-range ejection fraction or preserved ejection fraction (HFmrEF/HFpEF), and patients with left EF ≤ 40%, categorized under HF with reduced ejection fraction (HFrEF).RESULTSOur model predicted an average of 0.09 quality-adjusted life year (QALY) gains among HFmrEF/HFpEF patients and HFrEF patients when empagliflozin was compared to SoC. The addition of empagliflozin in the treatment results in a discounted incremental lifetime cost of PHP 62,692 (USD 1,129.99) and PHP 17,215 (USD 308.67) for HFmrEF/HFpEF and HFrEF, respectively. The incremental cost-effectiveness ratio (ICER) of empagliflozin is PHP 198,270 (USD 3,570.72)/QALY and PHP 742,604 (USD 13,385.08)/QALY for HFrEF and HFmrEF/HFpEF, respectively.LIMITATIONSThis study employed parameters derived from short-term clinical trial data, alongside metrics representative of Asian populations, which are not specific to the Philippine cohort.CONCLUSIONSAdding empagliflozin to the SoC in comparison to the SoC is associated with improved clinical outcomes and quality-of-life, at additional costs for both HFrEF and HFmrEF/HFpEF.
