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.

Clinical Trials Related to Kogenate (Antihemophilic Factor)
Study to Establish Bioequivalence of ReFacto AF (BDDrFVIII) With Advate (FLrFVIII) in Hemophilia A [Completed]
The study will consist of two parts: a safety and efficacy period in which all subjects will
participate and a pharmacokinetic analysis period, in which 30 eligible subjects will
participate to compare ReFacto AF and Advate bioequivalency and safety and efficacy of
ReFacto AF in patients with Hemophilia A.
Assessment of the Risk of Inhibitor Formation in Previously Treated Patients With Severe Hemophilia A [Terminated]
Most transient inhibitor formation, if any, will develop within the first 4 weeks. The study
is to further monitor whether participants with severe Hemophilia A will develop inhibitors
or antibodies at the later stage when switched from their current recombinant therapy
produced from Chinese Hamster Ovary (CHO) cell line to KogenateŽ-FS raised in a Baby Hamster
Kidney cell line.

Dose-Response Study of Recombinant Factor VIII Manufactured Protein-Free (rAHF-PFM) in Patients With Hemophilia A [Active, not recruiting]
The purpose of this study is to determine the effect of 3 doses of ADVATE rAHF-PFM on initial
recovery (% increase [IU/dL] per IU/kg infused) and major single-infusion pharmacokinetic
parameters. The 3 doses are 15, 30, and 50 IU/kg. Prior to each infusion, subjects will not
have received treatment with a factor VIII concentrate for at least 3 days. Blood samples
will be drawn within 30 minutes pre-infusion and at 0. 25, 0. 5, 1, 3, 6, 9, 24, 28, 32 and 48
hours post-infusion. A washout period of at least 3 days, but no more than 30 days between
the last blood draw and the next infusion will be observed. During participation, subjects
will maintain their preexisting treatment regimens with ADVATE rAHF-PFM or other factor VIII
A secondary objective is to investigate the relationship between pharmacokinetic parameters
at each dose level and the levels of von Willebrand factor ristocetin cofactor activity and
von Willebrand factor antigen at baseline.
