Abstract

The present disclosure relates to a method for increasing the stability of a Factor VIII molecule after purification, lyophilization and reconstitution, comprising preventing proteolytic cleavage of the Factor VIII molecule into a first fragment comprising essentially the A1 domain and the A2 domain and a second fragment comprising essentially the A3 domain, the C1 domain and the C2 domain throughout manufacturing the Factor VIII molecule. The disclosure further pertains to a method for improving the bioavailability of Factor VIII after intravenous and non-intravenous injection.
