Brief Summary:
The purpose of this study is to determine the immunologic and overall safety associated with long-term use of Alphanate in subjects diagnosed with severe hemophilia A (Factor VIII:C less than 0.01 IU/ml), who have been previously treated with plasma-derived Factor VIII products other than Alphanate and who have no history of developing either antibody inhibitors to Factor VIII or nonspecific inhibitors of coagulation.
Detailed Description:
This is a Phase IV, non-randomized, multicenter study of at least 50 evaluable subjects diagnosed with severe hemophilia A. Enrolled subjects will be treated at home and with in-clinic therapy exclusively with Alphanate as their sole source of Factor VIII concentrate for prophylaxis and treatment of all bleeding episodes and surgical procedures. Subjects will be treated for at least 2 years and a minimum of 50 exposure days, or if 50 exposure days are not reached, for a maximum of 30 months and in accordance with the subject's usual pre-study treatment regimen. Subjects will continue treatment as above or until they develop inhibitors to Factor VIII at a titer greater than or equal to 5 Bethesda units (BU/ml); Factor VIII becomes ineffective at providing hemostasis, or the subject exhibits severe or serious adverse events that prevent completion of the study.
