Abstract 10191: Dapagliflozin versus Empagliflozin for Improving Outcomes of Non-Diabetic Patients with Heart Failure and Reduced Ejection Fraction

Introduction: Patients with HF and reduced ejection fraction (HFrEF) are at high risk for CV mortality and HF-related hospitalizations (HHF). The Sodium-Glucose Transport protein 2 inhibitors (SGLT2i) dapagliflozin and empagliflozin improve the outcomes of non-diabetic patients with HFrEF. We aimed to compare their value for money for this indication. Hypothesis: Empagliflozin and dapagliflozin have comparable value for money for improving the HF outcomes of non-diabetic patients with HFrEF. Methods: SGLT2i data was extracted from published results of empagliflozin and dapagliflozin in the subgroups of patients without diabetes. The primary clinical outcome measure was a composite of HHF or CV mortality events. The economic measure was the cost needed to treat (CNT) to prevent one event, calculated by multiplying the one-year number needed to treat (NNT) to prevent one event by the annual cost of each therapy. Drug costs were based on the 2021 US National Average Drug Acquisition Cost prices. Secondary outcomes were the CNT to prevent one event of HHF and CV mortality as separate clinical outcomes. Sensitivity analysis was performed to mitigate differences between the trial’s populations Results: Treatment with empagliflozin in EMPEROR-REDUCED has resulted in an NNT of 29 (95% CI: 18-212) compared to 32 (95% CI: 21-72) with dapagliflozin in DAPA-HF. Accordingly the CNT to prevent one event of CVM or HHF was $139,115 (95% CI: $86,347-$1,016,976) and $144,751 (95% CI: $94,993-$325,690), respectively. The sensitivity analysis confirmed the primary results, but the CNT to prevent CV mortality is significantly lower with dapagliflozin (Fig. 1) Conclusions: Empagliflozin and dapagliflozin have comparable value for money for improving HF outcomes of non-diabetic patients with HFrEF, with an advantage for dapagliflozin in CV mortality.
