ABSTRACT

AIMS: A Markov model was adapted to assess the real-world cost-effectiveness of rivaroxaban, dabigatran and apixaban. Each of these non-vitamin K antagonist oral anticoagulants was compared with vitamin K antagonist for stroke prevention in patients with non-valvular atrial fibrillation in Spain. METHODS: All inputs were derived from real-world studies: baseline patient characteristics, clinical event rates, as well as persistence rates for the vitamin K antagonist treatment option. A meta-analysis of real-world studies provided treatment effect and persistence data for rivaroxaban, dabigatran and apixaban, each compared with vitamin K antagonist therapy. The model considered 3-month cycles over a lifetime horizon. The model outcomes included different costs, quality-adjusted life years and life-years gained. Sensitivity analyses were performed to test the robustness of the model. RESULTS: When compared with vitamin K antagonist, rivaroxaban incurred incremental costs of €77 and resulted in incremental quality-adjusted life years of 0.08. The incremental cost per quality-adjusted life year was €952. For the same comparison, the incremental cost per quality-adjusted life year for dabigatran was €4,612. Finally, compared with vitamin K antagonist, the incremental cost per quality-adjusted life year for apixaban was €32,015. The sensitivity analyses confirmed the robustness of the base case results. The probabilities to be cost-effective versus vitamin K antagonist were 94%, 86% and 35%, respectively, for rivaroxaban, dabigatran and apixaban, considering a willingness-to-pay threshold of €22,000 per quality-adjusted life year gained, based on a cost-effectiveness study of the Spanish National Health System. CONCLUSION: These results suggest that rivaroxaban and dabigatran are cost-effective versus vitamin K antagonist for stroke prevention in non-valvular atrial fibrillation, from the Spanish National Health System perspective.

ABSTRACT

Early benefit assessment in Germany under the legislative framework of AMNOG (Arzneimittelmarktneuordnungsgesetz) requires direct comparisons of the new drug with appropriate comparators determined by the Federal Joint Committee (G-BA). In case no head-to-head studies are available for direct comparisons, the submission of indirect comparisons is permitted to assess the additional benefit of the new drug. However, the Institute for Quality and Efficiency in Health Care (IQWiG) states a clear preference for head-to-head trials and defines strict requirements for indirect comparisons to be considered in the benefit assessment. Similar requirements also exist in other countries with mandatory health technology assessments (HTA), like France, England and Scotland. Our evaluation shows that a comparison of the different HTA regarding indirect comparisons is difficult. Overall, external preconditions and methodological requirements are demanding and hardly to fulfill by pharmaceutical companies for implementation of indirect comparisons in early benefit assessment. The determination of the appropriate comparators, outcomes, patient subgroups and study choice are the main target within indirect comparisons for the future. To compare and assess submitted indirect comparisons it would be desirable that a transparent process was established, including the mandatory publication of HTA-reports within Europe and international guidelines, accepted by a large number of HTA-agencies.

ABSTRACT

QUESTION UNDER STUDY: The aim of this study was to evaluate the cost-effectiveness of ticagrelor and generic clopidogrel as add-on therapy to acetylsalicylic acid (ASA) in patients with acute coronary syndrome (ACS), from a Swiss perspective. METHODS: Based on the PLATelet inhibition and patient Outcomes (PLATO) trial, one-year mean healthcare costs per patient treated with ticagrelor or generic clopidogrel were analysed from a payer perspective in 2011. A two-part decision-analytic model estimated treatment costs, quality-adjusted life years (QALYs), life years and the cost-effectiveness of ticagrelor and generic clopidogrel in patients with ACS up to a lifetime at a discount of 2.5% per annum. Sensitivity analyses were performed. RESULTS: Over a patient's lifetime, treatment with ticagrelor generates an additional 0.1694 QALYs and 0.1999 life years at a cost of CHF 260 compared with generic clopidogrel. This results in an Incremental Cost Effectiveness Ratio (ICER) of CHF 1,536 per QALY and CHF 1,301 per life year gained. Ticagrelor dominated generic clopidogrel over the five-year and one-year periods with treatment generating cost savings of CHF 224 and 372 while gaining 0.0461 and 0.0051 QALYs and moreover 0.0517 and 0.0062 life years, respectively. Univariate sensitivity analyses confirmed the dominant position of ticagrelor in the first five years and probabilistic sensitivity analyses showed a high probability of cost-effectiveness over a lifetime. CONCLUSION: During the first five years after ACS, treatment with ticagrelor dominates generic clopidogrel in Switzerland. Over a patient's lifetime, ticagrelor is highly cost-effective compared with generic clopidogrel, proven by ICERs significantly below commonly accepted willingness-to-pay thresholds.
