• Migalastat (Galafold) is indicated for the treatment of adults with a confirmed diagnosis of Fabry disease and an amenable galactosidase alpha gene (GLA) variant based on in vitro assay data. It is used to manage cardiovascular manifestations, which are common in Fabry disease patients and represent the leading cause of death.
• Two systematic reviews/meta-analyses discussed the effectiveness and safety profile of Galafold compared to other treatments such as enzyme replacement therapy (ERT).
• The first study highlights that while ERT and chaperone therapy like migalastat are recommended for patients exhibiting cardiovascular involvement due to Fabry disease, their efficacy remains unclear. This uncertainty stems from high heterogeneity among studies regarding design, outcome measurements, making it difficult to assess the impact of these therapies on cardiovascular manifestations.
• In addition to its role in managing cardiovascular symptoms associated with Fabry Disease, Galafold has been noted for its potential use in treating gastrointestinal (GI) symptoms commonly experienced by these patients, according to the second study reviewed.
• Not all FD patients presenting GI symptoms respond favorably toward enzyme replacement or chaperone treatment, necessitating symptomatic relief. Therefore, more research is needed into alternative therapeutic options or strategies for this patient subgroup who do not respond well to the current standard of care, including migalastat.
• Both studies underscored a need for further investigation into larger cohorts using standardized clinical outcomes measures to better understand how effectively drugs like Galafold can address the various symptomatology related to Fabry Disease, especially those involving the heart or digestive system complications.
