Background: Sacubitril-valsartan therapy reduces cardiovascular mortality compared with enalapril therapy in patients with heart failure with reduced ejection fraction.
Objective: To evaluate the cost-effectiveness of sacubitril-valsartan versus angiotensin-converting enzyme inhibitor therapy in patients with chronic heart failure.
Design: Markov decision model.
Data Sources: Clinical trials, observational analyses, reimbursement data from the Centers for Medicare & Medicaid Services, drug pricing databases, and Centers for Disease Control and Prevention life tables.
Target Population: Patients with an average age of 64 years, New York Heart Association (NYHA) class II to IV heart failure, and a left ventricular ejection fraction of 0.40 or less.
Time Horizon: Lifetime.
Perspective: Societal.
Intervention: Treatment with sacubitril-valsartan or lisinopril.
Outcome Measures: Life-years, quality-adjusted life-years (QALYs), costs, heart failure hospitalizations, and incremental cost-effectiveness ratios.
Results of Base-Case Analysis: The sacubitril-valsartan group experienced 0.08 fewer heart failure hospitalization, 0.69 additional life-year, 0.62 additional QALY, and $29 203 in incremental costs, equating to a cost per QALY gained of $47 053. The cost per QALY gained was $44 531 in patients with NYHA class II heart failure and $58 194 in those with class III or IV heart failure.
Results of Sensitivity Analysis: Sacubitril-valsartan treatment was most sensitive to the duration of improved outcomes, with a cost per QALY gained of $120 623 if the duration was limited to the length of the trial (median, 27 months). No variations in other parameters caused the cost to exceed $100 000 per QALY gained.
Limitation: The benefit of sacubitril-valsartan is based on a single clinical trial.
Conclusion: Treatment with sacubitril-valsartan provides reasonable value in reducing cardiovascular mortality and morbidity in patients with NYHA class II to IV heart failure.
