Open-Label Study of Asfotase Alfa in Infants and Children ≤ 5 Years of Age With Hypophosphatasia (HPP)

Hypophosphatasia Clinical Trial

Official title:
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)

Clinical Trial Summary

This clinical trial was conducted to study hypophosphatasia (HPP), a bone disorder caused by gene mutations or changes. These gene mutations cause low levels of an enzyme needed to harden bone. The purpose of this study was to test the safety and efficacy of a study drug called asfotase alfa (human recombinant tissue non-specific alkaline phosphate fusion protein) to see what effects it has on patients 5 years of age or less with HPP.

Clinical Trial Description

Asfotase alfa was formerly referred to as ENB-0040

Hypophosphatasia (HPP) is a life-threatening, genetic, and ultra-rare metabolic disease characterized by defective bone mineralization and impaired phosphate and calcium regulation that can lead to progressive damage to multiple vital organs, including destruction and deformity of bones, profound muscle weakness, seizures, impaired renal function, and respiratory failure. There are limited data available on the natural course of this disease over time, particularly in patients with the juvenile-onset form. ;
