Koate

Antihemophilic Factor (Human), Koatew-DVI, is a sterile, stable, purified, dried concentrate of human Antihemophilic Factor (AHF, factor VIII, AHG) which has been treated with tri-n-butyl phosphate (TNBP) and polysorbate 80 and heated in lyophilized form in the final container at 80°C for 72 hours. Koate (antihemophilic factor) -DVI is intended for use in therapy of classical hemophilia (hemophilia A).

Koate (antihemophilic factor) -DVI is purified from the cold insoluble fraction of pooled fresh-frozen plasma by modification and refinements of the methods first described by Hershgold, Pool, and Pappenhagen.1 Koate (antihemophilic factor) -DVI contains purified and concentrated factor VIII. The factor VIII is 300–1000 times purified over whole plasma. Part of the fractionation may be performed by another licensed manufacturer. When reconstituted as directed, Koate (antihemophilic factor) -DVI contains approximately 50–150 times as much factor VIII as an equal volume of fresh plasma. The specific activity, after addition of Albumin (Human), is in the range of 9–22 IU/mg protein. Koate (antihemophilic factor) -DVI must be administered by the intravenous route.

Each bottle of Koate-DVI contains the labeled amount of antihemophilic factor activity in international units (IU). One IU, as defined by the World Health Organization standard for blood coagulation factor VIII, human, is approximately equal to the level of AHF found in 1.0 mL of fresh pooled human plasma. The final product when reconstituted as directed contains not more than (NMT) 1500 μg/mL polyethylene glycol (PEG), NMT 0.05 M glycine, NMT 25μg/mL polysorbate 80, NMT 5μg/g tri-n-butyl phosphate (TNBP), NMT 3 mM calcium, NMT 1μg/mL aluminum, NMT 0.06 M histidine, and NMT 10 mg/mL Albumin (Human).

Koate (antihemophilic factor) -DVI is supplied in the following single dose bottles with the total units of factor VIII activity stated on the label of each bottle. A suitable volume of Sterile Water for Injection, USP, a sterile double-ended transfer needle, a sterile filter needle, and a sterile administration set are provided.

Storage

Koate (antihemophilic factor) -DVI should be stored under refrigeration (2–8°C; 36–46°F). Storage of lyophilized powder at room temperature (up to 25°C or 77°F) for 6 months, such as in home treatment situations, may be done without loss of factor VIII activity.

Freezing should be avoided as breakage of the diluent bottle might occur.

Allergic-type reactions may result from the administration of Antihemophilic Factor (Human) preparations.10,11

Ten adverse reactions related to 7 infusions were observed during a total of 1053 infusions performed during the clinical study of Koate (antihemophilic factor) -DVI, for a frequency of 0.7% infusions associated with adverse reactions. All reactions were mild and included tingling in the arm, ear, and face, blurred vision, headache, nausea, stomach ache, and jittery feeling.2
