  • Patent number: 9907835
    Abstract: The present invention provides a novel albumin-free preparation of Factor VIII has a high amount of salt and a low concentration of sugar and of glycine. The high salt provides stability and an elegant cake structure as the major crystalline component. The sugar and glycine provide a complex amorphous matrix together with some amorphous non-crystallized salt for stabilization of Factor VIII. This formulation is suitable for B-domain deleted Factor VIII that requires a high ionic strength environment for stability. The addition of low amount of glycine to the sucrose prevents the crystallization of salt. This results in an amorphous matrix comprising of glycine, sucrose, and salt. This amorphous matrix provides a stabilizing environment where Factor VIII is protected by three stabilizers; amino acid (glycine), sugar (sucrose or trehalose), and salt (NaCl). Such an amorphous matrix that can stabilize the Factor VIII across lyophilization and during storage as a lyophile.

  • Patent number: 9855319
    Abstract: The present invention provides a novel albumin-free formulation of recombinant Factor VIII that does not require calcium ions as an added formulation excipient. The absence of calcium chloride in the formulation results in a number of improvements and benefits for a Factor VIII formulation. This invention allows a Factor VIII formulation that can be lyophilized more efficiently as the absence of calcium ions will increase primary glass transition of the amorphous phase. The absence of free calcium ions in the formulation will also improve the stability of the formulation as metal-dependent oxidation reactions will be avoided and the protein molecule will not be subjected to chemical instabilities. Finally, the absence of calcium will further simplify the Factor VIII formulation by reducing the number of excipients in the formulation.
