Study of Pharmacokinetics, Efficacy and Safety of a Recombinant and Protein-Free Factor VIII (rAHF-PFM) in Hemophilia A Patients – A Continuation of Clinical Study 069901

Brief Title

Study of Pharmacokinetics, Efficacy and Safety of a Recombinant and Protein-Free Factor VIII (rAHF-PFM) in Hemophilia A Patients - A Continuation of Clinical Study 069901

Official Title

Evaluation of Pharmacokinetics, Safety, Efficacy and Immunogenicity of rAHF-PFM in Previously Treated Hemophilia A Patients - A Continuation Study

Brief Summary

      The purpose of this study is to evaluate whether rAHF-PFM is safe and effective in the
      treatment of hemophilia A subjects. The study consists of 2 parts: Part 1 is a
      pharmacokinetic and safety study, and Part 2 is an evaluation of efficacy and safety. The
      study is open to patients who completed Baxter Study 069901.

Eligibility Criteria

        Inclusion Criteria:

          -  Subject has completed Baxter protocol 069901

          -  Subject is HIV-1 seronegative or, if HIV-1 seropositive, has a CD4+ lymphocyte count
             >= 400/mm3 documented within three months of the screening visit

          -  Subject (and his legally acceptable representative, in the case of study participants
             >= 10 and < 18 years of age) has been informed of the nature of the study, agreed to
             its provisions, and signed and dated the informed consent form approved by the
             appropriate IRB/IEC and Baxter

        Exclusion Criteria:

          -  The subject received factor VIII products other than rAHF-PFM upon completion of
             Baxter protocol 069901

          -  The subject developed an inhibitor to factor VIII, measured in the central laboratory,
             during Baxter protocol 069901. An inhibitor is defined as a Bethesda titer > 1.0 or,
             if Bethesda titer < 1.0, confirmation using the Nijmegen modification of the Bethesda
             assay with a titer > 0.6

          -  The subject is scheduled to receive an immunomodulating drug other than
             anti-retroviral chemotherapy (e.g., a-interferon, steroids) during the course of the
             study

          -  The subject is identified by the investigator as being unable or unwilling to
             cooperate with study procedures
