Mean FVIII recovery at week 13 is increased in subjects compared with mean FVIII recovery before hFVIII(V). Data shown are from the 3 subjects who received hFVIII(V) dose no. 2 (9.2 × 10⁷ TU). Dashed line indicates FVIII recovery at week 13. Solid line indicates FVIII recovery at baseline pharmacokinetic study. FVIII incremental recovery is calculated as the percentage FVIII measured in plasma per unit of FVIII concentrate infused per kilogram body weight.
