Outcome Measures

Primary Outcomes (4)

  • Area Under the Plasma Concentration Versus Time Curve (AUC) From 0 to 48 Hours. One-Stage Activated Partial Thromboplastin Time (aPTT) -Based Assay Performed at Central Laboratory (Medical University Vienna)

    AUC estimated by linear trapezoidal method. The linear trapezoidal method is a numerical method used to approximate the area under a curve.

    0-30 minutes before infusion up to 48 hours post-infusion

  • Area Under the Plasma Concentration Versus Time Curve (AUC) From 0 to 48 Hours. Chromogenic Assay Performed at Local Laboratory (i.e., University of Bonn, the Study Site)

    AUC estimated by linear trapezoidal method. The linear trapezoidal method is a numerical method used to approximate the area under a curve.

    0-30 minutes before infusion up to 48 hours post-infusion

  • Area Under the Plasma Concentration Versus Time Curve (AUC) From 0 to 48 Hours. FVIII One-Stage Clotting Assay (Bonn Method) Performed at Local Laboratory (i.e., University of Bonn, the Study Site)

    AUC estimated by linear trapezoidal method. The linear trapezoidal method is a numerical method used to approximate the area under a curve.

    0-30 minutes before infusion up to 48 hours post-infusion

  • Area Under the Plasma Concentration Versus Time Curve (AUC) From 0 to 48 Hours. FVIII Clotting Assay. Performed at Local Laboratory (i.e., University of Bonn, the Study Site)

    AUC estimated by linear trapezoidal method. The linear trapezoidal method is a numerical method used to approximate the area under a curve.

    0-30 minutes before infusion up to 48 hours post-infusion

Secondary Outcomes (32)

  • Area Under the Plasma Concentration Versus Time Curve (AUC) From 0 to Infinity. Chromogenic Assay Performed at Local Laboratory (i.e., University of Bonn, the Study Site)

    0-30 minutes before infusion up to 48 hours post-infusion

  • Area Under the Plasma Concentration Versus Time Curve (AUC) From 0 to Infinity. FVIII One-Stage Clotting Assay (Bonn Method) Performed at Local Laboratory (i.e., University of Bonn, the Study Site)

    0-30 minutes before infusion up to 48 hours post-infusion

  • Area Under the Plasma Concentration Versus Time Curve (AUC) From 0 to Infinity. FVIII Clotting Assay. Performed at Local Laboratory (i.e., University of Bonn, the Study Site)

    0-30 minutes before infusion up to 48 hours post-infusion

  • Systemic Clearance (Cl). One-Stage aPTT-Based Assay Performed at Central Laboratory (Medical University Vienna)

    0-30 minutes before infusion up to 48 hours post-infusion

Eligibility Criteria

Age15 Years - 60 Years
Sexall
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64)

You may qualify if:

  • Signed informed consent obtained from participant or legally authorized representative
  • years old
  • Factor VIII level \< 1% as documented by previously measured factor VIII and genotyping
  • Previously treated with factor VIII concentrate(s) for a minimum of at least 150 exposure days (as documented by the study site investigator) prior to study entry
  • Observed decrease of efficacy by subject and/or treating physician after being switched from Recombinate rAHF to Advate rAHF-PFM

You may not qualify if:

  • The participant has a detectable factor VIII inhibitor at screening, with a titer \>= 0.4 Bethesda Unit (BU) (Nijmegen modification of the Bethesda Assay) measured at the local and the central laboratory
  • The participant has a known hypersensitivity to mouse or hamster proteins
  • The participant is participating in another investigational drug study within 30 days prior to screening
  • The participant is identified by the investigator as being unable or unwilling to cooperate with study procedures
