Other Information
Kogenate FS, Antihemophilic Factor (Recombinant), is a coagulation factor VIII produced by recombinant DNA technology. It is produced by Baby Hamster Kidney (BHK) cells into which the human factor VIII gene has been introduced.8 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 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 factor VIII derived from human plasma. No human or animal proteins, such as albumin, are added during the purification and formulation processes of Kogenate FS.
The purification process includes a solvent/detergent virus inactivation step in addition to the use of the purification methods of ion exchange chromatography, monoclonal antibody immunoaffinity chromatography, along with other chromatographic steps designed to purify recombinant factor VIII and remove contaminating substances.
Additionally, the manufacturing process was investigated for its capacity to decrease the infectivity of an experimental agent of transmissible spongiform encephalopathy (TSE), considered as a model for the vCJD and CJD agents.9-13 Several of the individual production and raw material preparation steps in the Kogenate FS manufacturing process have been shown to decrease TSE infectivity of that experimental model agent. These TSE reduction steps include the Fraction II+III separation step for HPPS (6.0 log10) and an anion exchange chromatography step (3.6 log10).
Kogenate FS is formulated with the following as stabilizers (see Table 6) in the final container and is then lyophilized. The final product does not contain any preservative. It is a sterile, nonpyrogenic powder preparation for intravenous injection. Intravenous administration of sucrose contained in Kogenate FS will not affect blood glucose levels.

2.1 Dose • Dosage and duration of treatment depend on the severity of the factor VIII deficiency, the location and extent of bleeding, and the patient’s clinical condition. 1 Careful control of replacement therapy is especially important in cases of major surgery or life-threatening bleeding episodes. • Each vial of Kogenate FS has the recombinant factor VIII (rFVIII) potency in international units (IU, unit) stated on the label. One IU (unit), as defined by the World Health Organization standard for blood coagulation factor VIII, human, is approximately equal to the level of factor VIII activity found in 1 mL of fresh pooled human plasma. • The expected in vivo peak increase in factor VIII level expressed as IU/dL (or % normal) can be estimated using the following formulas: Dosage (units) = body weight (kg) x desired factor VIII rise (IU/dL or % of normal) x 0.5 (IU/kg per IU/dL) or IU/dL (or % normal) = Total Dose (IU)/body weight (kg) x 2 [IU/dL]/[IU/kg] • Titrate dose to the patient’s clinical response. Patients may vary in their pharmacokinetic (e.g., half-life, in vivo recovery) and clinical responses to Kogenate FS. 2,3,4 Although the dose can be estimated by the calculations above, it is highly recommended that appropriate laboratory tests, including serial factor VIII activity assays, are performed [see Warnings and Precautions (5.3) and Clinical Pharmacology (12.3)]. Control and Prevention of Bleeding EpisodesA guide for dosing Kogenate FS for the control and prevention of bleeding episodes is provided in Table 1. The goal of treatment is to maintain a plasma factor VIII activity level at or above the plasma levels (in % of normal or in IU/dL) outlined in Table 1.

2.2 Preparation and ReconstitutionKogenate FS is administered by intravenous injection after reconstitution. Patients should follow the specific reconstitution and administration procedures provided by their physicians.
Reconstitute and administer Kogenate FS with the components provided with each package. If any component of the package is opened or damaged, do not use this component.
Product reconstitution, administration, and handling of the administration set and needles must be done with caution because percutaneous puncture with a needle contaminated with blood can transmit infectious viruses, including HIV (AIDS) and hepatitis. Place needles in a sharps container after single use. Discard all equipment, including any reconstituted Kogenate FS product, in an appropriate container. Obtain immediate medical attention if injury occurs.
For any questions about the handling, reconstitution and administration of Kogenate FS, contact Bayer Medical Communications at 1-888-84-BAYER (1-888-842-2937).
For instructions, patients should follow the recommendations in the FDA-Approved Patient Labeling.
The procedures below are provided as general guidelines for the reconstitution of Kogenate FS.
• Work on a clean surface and wash hands thoroughly using soap and warm water before performing the procedures. • Reconstitute the product with the components provided with each package. If any component of the package is opened or damaged, do not use this component. • Filter the reconstituted product to remove potential particulate matter in the solution. Filtering can be achieved by following the reconstitution steps as described below.Vacuum Transfer and Reconstitution
1. Prepare the product under aseptic conditions. 2. Warm the unopened diluent and the concentrate to a temperature not to exceed 37°C or 99°F. 3. After removing the plastic flip-top caps (Fig. A), aseptically cleanse the rubber stoppers of both vials with alcohol, being careful not to handle the rubber stopper. 4. Remove the protective cover from one end of the plastic transfer needle cartridge and penetrate the stopper of the diluent vial (Fig. B). 5. Remove the remaining portion of the protective cover, invert the diluent vial and penetrate the rubber seal on the concentrate vial (Fig. C) with the needle at an angle. 6. The vacuum will draw the diluent into the concentrate vial. Hold the diluent vial at an angle to the concentrate vial in order to direct the jet of diluent against the wall of the concentrate vial (Fig. C). Avoid excessive foaming. If the diluent does not get drawn into the vial, there is insufficient vacuum and the product should not be used. 7. After removing the diluent vial and transfer needle (Fig. D), swirl until completely dissolved without creating excessive foaming (Fig. E). 8. Re-swab top of reconstituted Kogenate FS vial with alcohol. Allow the stopper to air dry. 9. After the concentrate powder is completely dissolved, withdraw the solution into the syringe through the filter needle that is supplied in the package (Fig. F). Replace the filter needle with the administration set provided and inject intravenously. 10. If the same patient is to receive more than one vial, the contents of two vials may be drawn into the same syringe through a separate unused filter needle before attaching the vein needle. 2.3 AdministrationFor intravenous use after reconstitution only.
• Inspect Kogenate FS visually for particulate matter and discoloration prior to administration, wherever solution and container permit. Do not use Kogenate FS if you notice any particulates or turbidity in the solution. • Store the reconstituted Kogenate FS at room temperature prior to administration, but administer it within 3 hours. • Administer Kogenate FS with the administration set provided with the product as it incorporates an in-line filter. In situations where the administration set provided cannot be used (e.g. when infusing into a peripheral or central line), use a separate filter compatible with Kogenate FS. NOTE: Do not use the administration set provided with the product to draw blood because it contains an in-line filter. When blood must be withdrawn prior to an infusion, use an administration set without a filter, then infuse Kogenate FS through an injection filter. For any questions about compatible separate filters, contact Bayer Medical Communications at 1-888-84-BAYER (1-888-842-2937). • Administer Kogenate FS over a period of 1 to 15 minutes. Adapt the rate of administration to the response of each individual patient. Determine the pulse rate before and during administration of Kogenate FS. If there is a significant increase in pulse rate, reduce the rate of administration or temporarily halt the infusion allowing the symptoms to disappear promptly. -

• Inspect Kogenate FS visually for particulate matter and discoloration prior to administration, wherever solution and container permit. Do not use Kogenate FS if you notice any particulates or turbidity in the solution. • Store the reconstituted Kogenate FS at room temperature prior to administration, but administer it within 3 hours. • Administer Kogenate FS using the administration set provided over a period of 1 to 15 minutes. Adapt the rate of administration to the response of each individual patient. Determine the pulse rate before and during administration of Kogenate FS. If there is a significant increase in pulse rate, reduce the rate of administration or temporarily halt the infusion allowing the symptoms to disappear promptly.
