Study 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.

Primary Outcome

The effect of asfotase alfa treatment on skeletal manifestations of HPP (i.e., change in rickets severity) was measured by radiographs using a qualitative Radiographic Global Impression of Change (RGI-C) scale. Skeletal radiographs obtained at Week 24 were compared with skeletal radiographs obtained before initiation of treatment. The RGI-C is a 7-point rating scale that ranges from -3 (indicative of severe worsening of HPP-associated rickets) to +3 (indicative of complete or near complete heali
