KOGENATE SUMMARY
Kogenate® FS Antihemophilic Factor (Recombinant) is a sterile, stable, purified, nonpyrogenic, dried concentrate that has been manufactured using recombinant DNA technology. Kogenate FS is intended for use in the treatment of classical hemophilia (hemophilia A), and is produced by Baby Hamster Kidney (BHK) cells into which the human factor VIII (FVIII) gene has been introduced.1 The cell culture medium contains Human Plasma Protein Solution (HPPS) and recombinant insulin, but does not contain any proteins derived from animal sources. Kogenate FS is a highly purified glycoprotein consisting of multiple peptides including an 80 kD and various extensions of the 90 kD subunit. It has the same biological activity as FVIII derived from human plasma. Compared to its predecessor product KOGENATE® Antihemophilic Factor (Recombinant), Kogenate FS incorporates a revised purification and formulation process that eliminates the addition of Albumin (Human).
Kogenate FS is indicated for the treatment of classical hemophilia (hemophilia A) in which there is a demonstrated deficiency of activity of the plasma clotting factor FVIII. Kogenate FS provides a means of temporarily replacing the missing clotting factor in order to correct or prevent bleeding episodes, or in order to perform emergency or elective surgery in hemophiliacs.
In clinical studies with the predecessor productKOGENATE, some patients who developed inhibitors on study continued to manifest a clinical response when inhibitor titers were less than 10 Bethesda Units (BU) per mL. When an inhibitor is present, the dosage requirement for FVIII is variable. The dosage can be determined only by clinical response, and by monitoring circulating FVIII levels after treatment (see DOSAGE AND ADMINISTRATION). Because Kogenate FS has similar biological activity toKOGENATE it can be used in the same manner.
Kogenate FS does not contain von Willebrand's factor and therefore is not indicated for the treatment of von Willebrand's disease.
