Abstract: | The use of plasma-derived products has contributed to a high rate of blood-borne infections among haemophilia patients in China. Recombinant factor VIII (rFVIII) products that are manufactured without human or bovine albumin and include dedicated viral inactivation steps, hold a significant safety advantage over plasma products. However, there is little information published on the use of rFVIII products in non-caucasian populations. This is the first reported evaluation of the efficacy and safety of a rFVIII product in Chinese haemophiliacs. An open-label, non-randomized, prospective, multicentre trial enroled previously treated Chinese patients with haemophilia A. All treatments were administered using a sucrose-formulated rFVIII-FS (Kogenate((R))). Forty-nine patients received totals of 291 infusions (mean, 5.94/patient) and 742 140 IU rFVIII-FS (mean, 2550.3 IU/infusion). Of the 60 acute bleeding episodes that were treated, 90% were successfully managed with only one (81.7%) infusion or two (8.3%) infusions. Physicians reported haemostasis control for acute bleeds to be 'Excellent' or 'Improved' with rFVIII-FS therapy. No FVIII inhibitors were detected in any patient. Only one treatment-related adverse event was reported, which was mild dizziness that resolved spontaneously. rFVIII-FS was efficacious, safe and well tolerated in the treatment of previously treated patients with haemophilia A in China. |
