Treatment That Mimics Natural Factor VIII

AFSTYLA uses a novel single-chain design to provide long-lasting bleed protection

What is single-chain design?

A strong molecular bond: In AFSTYLA, the two molecular chains that make up Factor VIII are joined by a strong bond to create one molecule.

Increased stability in the bloodstream: This novel single-chain design allows increased binding affinity to other blood components (von Willebrand factor), which keeps Factor VIII in circulation longer.

Factor VIII becomes activated in your bloodstream when it needs to help create a clot and stop a bleed. Activated AFSTYLA is identical to natural Factor VIII.
