Value contribution of etranacogene dezaparvovec gene therapy in moderately severe and severe haemophilia B through multi-criteria decision analysis.

Introduction: The value of gene therapies for haemophilia needs to be assessed holistically.

Aim: To determine the value of etranacogene dezaparvovec (ED) compared to current extended half-life (EHL) recombinant factors (rFIX), using multi-criteria decision analysis (MCDA).

Method: MCDA EVIDEM methodology adapted to orphan drugs was used, with nine quantitative criteria and four contextual criteria.
