The efficacy and safety of an advanced category recombinant antihaemophilic factor produced by a plasma- and albumin-free method (rAHF-PFM) was studied in 111 previously treated subjects with haemophilia A. The study comprised a randomized, double-blinded, crossover pharmacokinetic comparison of rAHF-PFM and RECOMBINATE rAHF (R-FVIII); prophylaxis (three to four times per week with 25-40 IU kg-1 rAHF-PFM) for at least 75 exposure days; and treatment of episodic haemorrhagic events. Median age was 18 years, 96% of subjects had baseline factor VIII -1 year-1) than subjects who were more adherent (4.4 episodes subject-1 year-1; P <0.03). One subject developed a low titre, non-persistent inhibitor (2.0 BU) after 26 exposure days. These data demonstrate that rAHF-PFM is bioequivalent to R-FVIII, and suggest that rAHF-PFM is efficacious and safe, without increased immunogenicity, for the treatment of haemophilia A.
