ATC Group: B02BD02 Coagulation factor VIII

Activated factor VIII acts as a cofactor for activated factor IX, accelerating the conversion of factor X to activated factor X (factor Xa). Haemophilia A is a sex-linked hereditary disorder of blood coagulation due to decreased levels of factor VIII:C. By replacement therapy the plasma levels of factor VIII are increased, thereby enabling a temporary correction of the factor deficiency and correction of the bleeding tendencies.

Lonoctocog alfa is a recombinant human protein that replaces the missing coagulation factor VIII needed for effective hemostasis. Lonoctocog alfa is a single polypeptide chain with a truncated B-domain that allows for a covalent bridge to link the factor VIII heavy and light chains. Lonoctocog alfa has demonstrated a higher VWF affinity relative to full-length rFVIII. VWF stabilizes factor VIII and protects it from degradation. Activated lonoctocog alfa has an amino acid sequence identical to endogenous FVIIIa.

Moroctocog alfa is a B-domain deleted recombinant coagulation factor VIII. Moroctocog alfa has functional characteristics comparable to those of endogenous factor VIII. Haemophilia A is a sex-linked hereditary disorder of blood coagulation due to decreased levels of factor VIII:C. By replacement therapy, the plasma levels of factor VIII are increased, thereby enabling a temporary correction of the factor deficiency and correction of the bleeding tendencies.

Octocog alfa (Full length recombinant human coagulation factor VIII (rDNA)) is a purified protein that has 2,332 amino acids. It is produced by recombinant DNA technology in baby hamster kidney cells (BHK) into which the human factor VIII gene has been introduced.
