FDA decision deadline on extending GALAFOLD to pediatric Fabry patients aged 2 to <12 with amenable GLA mutations. GALAFOLD is currently approved for ages 12+; alternative ERT in same disease: Fabrazyme (Sanofi).
What’s at stake
GALAFOLD (migalastat) is an oral pharmacological chaperone developed by Amicus Therapeutics taken every other day for Fabry disease — an X-linked lysosomal storage disorder in which GLA mutations impair the alpha-galactosidase A (alpha-Gal A) enzyme, causing glycolipid accumulation in blood vessels, kidneys, heart, and nerves that leads to renal failure, cardiomyopathy, and early stroke. Rather than replacing the enzyme from outside the cell, migalastat enters cells and stabilizes specific misfolded mutant alpha-Gal A proteins, allowing them to reach the lysosome and function. GALAFOLD is approved for patients aged 12+ with amenable GLA mutations; Amicus is pursuing approval for children aged 2 to under 12.
