Survey of Inhibitors in Plasma-Product Exposed Toddlers

Summary

The primary objective of the study is to assess the immunogenicity of VWF/FVIII and of rFVIII concentrates by determining the frequency of inhibitor development in previously untreated patients (PUPs) or minimally blood component-treated (MBCTPs) in the first 50 EDs or in the first 3 years from enrollment, whichever occurs first. .
