In this study, we aimed to assess the PK parameters of FVIII products in boys with severe HA in China. Methods: A total of 36 boys (plasma-derived [pd]-FVIII, n= 15; recombinant [r] FVIII, n = 21) were enrolled between January 2015 and May 2016 in Beijing Children's Hospital. PK characteristics of FVIII products were studied according to a reduced 4-sampling time point design (1 h, 9 h, 24 h, and 48 h postinfusion). Results: The mean FVIII half-life (t1/2) was 10.99 ± 3.45 h (range 5.52-20.02 h), the mean in vivo recovery (IVR) was 2.01 ± 0.42 IU/dl per IU/kg (range 1.24-3.02 IU/dl per IU/kg) and mean clearance (CL) of FVIII is 4.34 ± 1.58 ml·kg^-1·h ^-1 (range 2.29-7.90 ml·kg^-1·h·^-1). We also analyzed the influence of several parameters that potentially modulate FVIII PK. The age was closely associated with FVIII half-life (R^2 = 0.32, P 〈 0.01 ). The t1/2 of FVIII increased by 0.59 h per year. Besides age, yon Willebrand factor antigen (VWF:Ag) also was associated with FVIII half-life (R^2 = 0.52, P 〈 0.01). Patients with blood Group O had a shorter FVIII halt-life than patients with non-O blood group (9.40 ± 0.68 h vs. 12.3 ± 0.79 h, t = 2.70, P = 0.01). The FVIII IVR correlated with age (R^2 =0.21, P 〈 0.01) and VWF:Ag level (R^2 = 0.28, P 〈 0.01 ). CL rates were taster in young patients and in those with low-VWF:Ag levels. CL rates of FVIII are higher in blood Group O versus non-blood Group O persons (5.02 ± 0.38 vs. 4.00 ± 0.32 ml·kg^-1·h^-1 , t = 2.53, P = 0.02). Conclusions: Chinese boys with severe HA have similar PK values to other ethnic groups and large differences in FVIII PK between individual patients.
