Summary

A recombinant FVIII preparation, Recombinate^™, was compared with a high-purity plasma-derived concentrate, Hemofil^® M, in 47 hemophilia A patients in a cross-over evaluation of pharmacokinetic properties. The recombinant material showed a significantly lower clearance, volume of distribution, and higher in vivo recovery, but a similar half-life to the plasma-based product.

In a comparison with reported data from other standard concentrates, the recombinant preparation exhibited potentially better pharmacokinetic properties in that its clearance was slower and its half-life was longer.

We conclude that the recombinant DNA method of preparation does not adversely affect the biological and pharmacological characteristics of the factor VIII molecule.
