Study Description
Brief Summary:
This study will examine the efficacy and safety of ReFacto AF in patients with severe and moderately severe hemophilia A undergoing elective major surgery when administered by either bolus injections (BI) or continuous infusion (CI).

Condition or disease Intervention/treatment Phase
Hemophilia A Biological: ReFacto AF Phase 3

Study Design

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 30 participants
Allocation: Non-Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: An Open Label Multi-center Study to Assess the Efficacy and Safety of B-Domain Deleted Recombinant Factor VIII (BDDrFVIII, ReFacto AF) in Patients With Hemophilia A Undergoing Elective Major Surgery
Study Start Date : April 2006
Primary Completion Date : June 2008
Study Completion Date : June 2008


Arms and Interventions

Arm Intervention/treatment
Experimental: A Biological: ReFacto AF
Experimental: B Biological: ReFacto AF


Outcome Measures

Primary Outcome Measures :
  1. Number of Patients Who Achieved Hemostatic Efficacy After Surgery [ Time Frame: 6 weeks ]
    Efficacy at the end of surgery as determined by the investigator and/or the surgeon using the 4 point ordinal scale (Excellent, Good, Moderate or None). Excellent: Achieved hemostatic comparable to non-hemophilic patients. Good: Prolonged time to hemostasis (with somewhat increased bleeding compared to non-hemophilic patients.


Secondary Outcome Measures :
  1. Number of Patients Who Achieved Hemostatic Efficacy at Hospital Discharge [ Time Frame: 6 weeks ]
    Assessment of hemostatic efficacy by the investigator at the day of discharge from the hospital using the 4 point ordinal scale (Excellent, Good, Moderate or None). Excellent: Achieved hemostatic comparable to non-hemophilic patients. Good: Prolonged time to hemostasis (with somewhat increased bleeding compared to non-hemophilic patients.
