Brief Summary
The purpose of this study is to collect safety information associated with the use of Xyntha in a usual care setting. Upon meeting eligibility criteria, patients will be required to have approximately 5 study visits over a 2 year period. Procedures completed throughout the study include collection of vital signs, physical exams, and laboratory assessments. Patients will be required to complete an infusion log for each Xyntha infusion.
