Abstract

Aims: To assess the cost-effectiveness of pro-protein convertase subtilisin/kexin type 9 (PCSK9) inhibitors in cardiovascular disease. Methods and results: We performed a comprehensive search strategy in electronic databases from January 2015 to January 2019. Out of 475 articles, 16 were entered into the study. Quality-adjusted life year, life years gained (LYG), annual cost, and the incremental cost-effectiveness ratio (ICER) regarding the use of PCSK9 inhibitors were considered as the key outcomes. The cost-effectiveness threshold varied from $45,000 in Spain to $150,000 in the USA. The annual cost of PCSK9 inhibitors for studies undertaken in the USA was in the range of $14,000 to $15,000, while it was about $7000 for other developed countries. The results showed that reduction in the price of PCSK9 inhibitors changed from 20 to 88%. The means of QALY were 0.65 and 0.67 in the Markov and Cardiovascular Disease Policy Modeling (CVDPM) models; also, the ICER means were $197,707 and $625,555 for the Markov and CVDPM model, respectively. Conclusion: According to the current study, the effectiveness of PCSK9 inhibitors is well documented, although all studies pointed out a higher cost of these inhibitors. Trial registration: This study was registered within the International Prospective Register of Systematic Reviews (PROSPERO) database of the University of York (CRD42018088472).
