An Open-Label, Multicenter, Multinational Study of the Safety, Efficacy and Pharmacokinetics of Asfotase alfa (human recombinant tissue nonspecific alkaline phosphatase fusion protein) in Infants and Children =5 Years of Age with Hypophosphatasia (HPP)Hypophosphatasia is a rare inborn error of bone metabolism caused by inactivating mutations in the gene encoding the Tissue-nonspecific alkaline phosphatase isoenzyme. With deficiency of Tissue-nonspecific alkaline phosphatase, there is a buildup of extracellular inorganic pyrophosphate, which inhibits mineralization of bone matrix.MedDRA version: 20.0Level: PTClassification code 10049933Term: HypophosphatasiaSystem Organ Class: 10010331 - Congenital, familial and genetic disordersEUCTR2010-019850-42-DEAlexion Pharma GmbH100
