The clinical efficacy and safety of the FVIII/VWF concentrate, BIOSTATE®, in children with von Willebrand disorder: a multi-centre retrospective review.
Factor replacement with BIOSTATE(®), a factor VIII (FVIII)/von Willebrand factor concentrate, forms the mainstay of treatment for children with von Willebrand disorder (VWD) in Australia and New Zealand. However, published data on the clinical efficacy and safety of BIOSTATE in the VWD paediatric population are limited. We retrospectively assessed the efficacy and safety of BIOSTATE in 43 children with VWD who received treatment for surgery, non-surgical bleeds or continuous prophylaxis at eight paediatric haemophilia centres in Australia and New Zealand. Data were collected on patient demographics, disease history, treatment history, dosage, administration, adverse reactions, concomitant medications and excessive bleeding events. BIOSTATE provided excellent/good haemostatic efficacy in 90% of surgical procedures (n = 42) with a mean daily FVIII dose of 47 IU FVIII:C kg(-1) and a median treatment duration of 3 days. Excellent/good haemostatic efficacy was achieved in 94% of non-surgical bleeding events (n = 72) with a mean FVIII dose of 45 IU FVIII:C kg(-1) day(-1) and a median treatment duration of 1 day. There were no bleeding events attributable to lack of efficacy. One case of nausea, possibly related to BIOSTATE administration, was reported. These results suggest that BIOSTATE is safe and effective for the treatment and prophylaxis of bleeding in children with VWD.
