Abstract
PURPOSE: To assess the cost-effectiveness of apixaban versus rivaroxaban, low-molecular-weight heparin (LMWH)/dabigatran, and LMWH/vitamin K antagonist (VKA) for the initial treatment and prevention of recurrent thromboembolic events in patients with venous thromboembolism (VTE).
METHODS: A Markov model was developed to evaluate the pharmacoeconomic effect of 6 months of treatment with apixaban versus other anticoagulants over a lifetime horizon. Network meta-analyses were conducted using the results of the Apixaban after the Initial Management of Pulmonary Embolism and Deep Vein Thrombosis with First-Line Therapy (AMPLIFY), EINSTEIN-pooled, and RE-COVER I and II trials for the following end points: recurrent VTE, major bleeds, clinically relevant non-major bleeds, and treatment discontinuations. The analysis was conducted from the perspective of the United Kingdom National Health Service. The outcomes evaluated were the number of events avoided in a 1000-patient cohort, total costs, life years, quality-adjusted life years (QALYs), and cost per QALY gained over a patient's lifetime.
FINDINGS: Treatment for 6 months with apixaban was projected to result in fewer recurrent VTE and bleeding events in comparison to rivaroxaban, LMWH/dabigatran, and LMWH/VKA. Apixaban was cost-effective compared with LMWH/VKA at an incremental cost-effectiveness ratio of £2520 per QALY gained and was a dominant (ie, lower costs and higher QALYs) alternative to either rivaroxaban or LMWH/dabigatran. Sensitivity analysis indicated that results were robust over a wide range of inputs.
IMPLICATIONS: The assessment of the effects and costs of apixaban in this study predicted that apixaban is a dominant alternative to rivaroxaban and LMWH/dabigatran and a cost-effective alternative to LMWH/VKA for 6 months of treatment of VTE and the prevention of recurrence.
