Abstract
AIMS: The Angiotensin Receptor-Neprilysin Inhibitor sacubitril-valsartan (ARNI) and dapagliflozin, a sodium-glucose transport protein 2 inhibitor, reduce the risk of heart failure hospitalization (hHF) and cardiovascular (CV) mortality in patients with reduced ejection fraction (HFrEF). Their comparative value for money is undetermined. Therefore, our aim was to compare the cost per outcome implications of utilizing dapagliflozin vs. ARNI for preventing heart failure (HF) events of non-diabetic patients with HFrEF. METHODS AND RESULTS: We calculated the cost needed to treat (CNT) to prevent one HF event. The cost needed to treat was estimated by multiplying the annualized number needed to treat (NNT) to prevent one event by each therapy's annual cost. Efficacy estimates were extracted from published secondary analyses of non-diabetic patients in DAPA-HF and PARADIGM-HF trials. Drug costs were estimated as 75% of the 2020 US National Average Drug Acquisition Cost listing. Sensitivity analysis was performed to mitigate differences between the trial's populations and drug costs in various countries.The annualized NNT to prevent one HF event for dapagliflozin was 31 (95% CI 21-71) vs. 33 (95% CI 24-62) for ARNI. The CNT of dapagliflozin in the US is $141 112 (95% CI $95 592-$323 192) compared to $158 169 (95% CI $115 032-$297 166) for sacubitril-valsartan. The CNT results were sensitive to drug costs in various countries. CONCLUSION: Dapagliflozin and ARNI provide comparable value for money for preventing HF events in non-diabetic patients with HFrEF. In healthcare settings where dapagliflozin's price is significantly lower than ARNI, it provides superior value for money. Published on behalf of the European Society of Cardiology.
