Introduction
FABRAZYME (agalsidase beta) is a recombinant form of the human enzyme alpha-galactosidase A, used for treating Fabry disease, a rare genetic disorder characterized by deficient enzyme activity leading to the accumulation of globotriaosylceramide in various tissues. Since its approval, FABRAZYME has established itself as a primary therapeutic option for Fabry disease, yet its market dynamics and financial outlook are influenced by complex factors spanning regulatory developments, patient demographics, competitive landscape, and innovation trajectories within the biologics sector.
Market Overview of Fabry Disease and FABRAZYME
Fabry disease affects approximately 1 in 40,000 to 117,000 males globally, with the incidence in females being harder to quantify due to X-linked inheritance and variable penetrance. The disease manifests via multi-organ involvement—renal, cardiac, cerebrovascular—driving the demand for effective enzyme replacement therapies (ERTs). Currently, FABRAZYME holds a dominant share of the ERT market for Fabry disease, alongside competing therapies such as Replagal (agalsidase alfa) by Takeda.
As a recombinant enzyme, FABRAZYME is administered intravenously, with treatment regimens typically requiring biweekly infusions. The therapy’s lifecycle is influenced by factors including clinical improvements, patient compliance, and regulatory pathways facilitating or hindering market access.
