  • Patent number: 5972885
    Abstract: A pharmaceutical formulation for subcutaneous, intramuscular or intradermal administration comprising recombinant coagulation factor VIII and use thereof for manufacture of a medicament for treating haemophilia is provided. The formulation comprises a highly purified recombinant coagulation factor VIII in a concentration of at least 1000 IU/ml, which gives surprisingly high levels of active factor VIII in the blood stream after subcutaneous, intramuscular or intradermal administration. The formulation is intended for treatment of haemophilia by subcutaneous, intramuscular or intradermal administration. The recombinant factor VIII is preferably a deletion derivative thereof, which can be used for the manufacture of a medicament for subcutaneous administration.

  • Patent number: 5962650
    Abstract: The present invention relates to a final drug product comprising coagulation factor VIII in an aqueous solution with a reduced concentration of oxygen. In this way, the factor VIII activity can be retained during storage to a surprisingly high degree. The factor VIII activity can be retained for a prolonged period of time, if the final drug product further comprises an inert gas and/or an antioxidant. The present invention also relates to processes for reducing the oxygen concentration of the aqueous solution, and a method for improving the stability of factor VIII in an aqueous solution by storing the solution under an inert gas atmosphere. By the present invention it is possible to retain at least 50% of the initial activity of factor VIII after storage for at least 6 months at a temperature of 2 to 10.degree. C. and a pH of the solution of 6.5 to 8.5.

  • Patent number: 5925739
    Abstract: The present invention relates to a pharmaceutical formulation for subcutaneous, intramuscular or intradermal administration comprising coagulation factor VIII or factor IX and use thereof for manufacture of a medicament for treating haemophilia A or B. The formulation comprises coagulation factor VIII or factor IX with an activity of at least 200 IU/ml and an additive increasing the bio-availability of factor VIII or factor IX. Tests with factor VIII gives a therapeutic level of active factor VIII in the blood stream for a surprisingly long period of time after subcutaneous, intramuscular or intradermal administration. The factor VIII is suitably a highly purified recombinant factor VII, and preferably a deletion derivative thereof, which can be used for the manufacture of a medicament for subcutaneous administration.

  • Patent number: 5919766
    Abstract: The present invention relates to a novel composition comprising coagulation Factor VIII and a non-ionic surfactant such as block co-polymers, e.g. polyoxamers or polyoxyethylene (20) fatty acid esters e.g. polysorbate 20 or polysorbate 80 as a stabilizer. The composition can also comprise sodium chloride, calcium chloride, L-histidine and/or sugars or sugar alcohols.

  • Patent number: 5919908
    Abstract: A final drug product comprises a plasma protein selected from the group consisting of coagulation factor VIII and factor IX, in an aqueous solution. The concentration of oxygen in the solution is reduced and/or the solution contains an antioxidant. The solution further contains a carbohydrate in a concentration of at least 350 mg/ml. The protein activity after storage for at least 6 months at a temperature of from 0.degree. C. to 40.degree. C. is from 70% to 130% of its initial value. In a process for preparing the final drug product and a method for improving the long-term stability of coagulation factor VIII or factor IX in an aqueous solution, a carbohydrate is included in the solution in a concentration of at least 350 mg/ml and the solution is stored in its final container under an oxygen-reduced atmosphere or includes an antioxidant.

  • Patent number: 5733873
    Abstract: A composition comprising coagulation factor VIII and a non-ionic surfactant such as block copolymers, e.g., polyoxamers or polyoxyethylene (20) sorbitan fatty acid esters, e.g., polysorbate 20 or polysorbate 80 as stabilizer is provided. The composition can also comprise sodium chloride, calcium chloride, L-histidine and/or sugars or sugar alcohols.
