Further study details as provided by Pfizer:

Primary Outcome Measures:
  • Incidence of clinically significant FVIII inhibitor development. [ Time Frame: 2 years ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Annualized bleeding rates (ABRs) in subjects receiving treatment with ReFacto AF. [ Time Frame: 2 years ] [ Designated as safety issue: No ]
  • Responses to the first on-demand treatment with ReFacto AF for all new bleeds (4 point scale of assessment) as assessed by the parent/legal representative. [ Time Frame: 2 years ] [ Designated as safety issue: No ]
  • Number of ReFacto AF infusions to treat each new bleed. [ Time Frame: 2 years ] [ Designated as safety issue: No ]
  • Number of bleeds within 48 hours of a preventive/prophylaxis dose of ReFacto AF. [ Time Frame: 2 years ] [ Designated as safety issue: No ]
  • Average infusion dose and total factor consumption, and the incidence of less-than-expected therapeutic effect (LETE). [ Time Frame: 2 years ] [ Designated as safety issue: No ]
  • Incidence of SAEs and nonserious AEs. [ Time Frame: 2 years ] [ Designated as safety issue: Yes ]

Ages Eligible for Study:   up to 11 Years
Genders Eligible for Study:   Male
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Male subjects less than 12 years of age with a documented history of severe hemophilia A (FVIII:C less than 1%).
  • Subjects who are less than 6 years of age must have had at least 50 Exposure Days (EDs) to prior FVIII products (including blood products).
  • Subjects who are equal to or greater than 6 years of age must have had greater than 150 EDs to prior FVIII products (including blood products).

Exclusion Criteria:

  • For laboratory assessments, any measured Bethesda inhibitor titer equal to or greater than 0.6 BU, regardless of the laboratory normal range, or any Bethesda inhibitor titer greater than ULN for the testing laboratory at the time of screening.
  • Any other bleeding disorder in addition to hemophilia A.
  • Treatment with any investigational drug or device within 30 days before the time of signing the parental informed consent/assent form.
  • Major surgery planned to occur during the course of the study.
  • Regular (e.g., daily; every other day) use of agents or medications known to influence platelet function such as aspirin or certain nonsteroidal anti-inflammatory drugs (NSAIDS).
  • Regular, concomitant therapy with immunomodulating drugs (e.g., intravenous immunoglobulin [IVIG], routine systemic corticosteroids), or currently receiving immune tolerance induction (ITI) for inhibitor treatment.
  • The subject is receiving treatment for HIV or hepatitis infection (unless the subject is on a stable antiviral regimen [i.e., consistent treatment regimen for at least 3 months before the parental informed consent/assent form is signed]).
  • Platelet count less than 100,000/µL.
  • Prothrombin time (PT) equal to or greater than 1.25 x ULN, or international normalized ratio (INR) equal to or greater than 1.5.
  • Known hypersensitivity to hamster protein.
