Abstract: The present invention provides a method of administering porcine B-domainless factor VIII (OBI-1) to a patient having factor VIII deficiency to provide more rapid and effective protection against bleeding episodes, compared to formerly available methods, or to provide more effective protection to such patients during non-bleeding periods. This invention is based on the discovery that the recombinant B-domainless porcine fVIII, termed OBI-1, has greater bioavailability compared to the natural porcine fVIII partially purified from porcine plasma, termed HYATE:C. Therefore, the inventive method employs lower unit doses of OBI-1, including, alternatively, omission of antibody-neutralizing dosage, or has longer intervals between the administration, compared to HYATE:C, to provide equivalent protection in patients having fVIII deficiency.

Abstract: This disclosure relates to composition and methods for improving blood clotting in a subject that developed anti-factor VIII antibodies. In certain embodiments, this disclosure contemplates a conjugate comprising a toxin, e.g., ricin, abrin, saporin, coupled to factor VIII or functional variant thereof either through a linking group or as a fusion protein.

Abstract: Methods of treating patients with Factor VIII deficiency by administration of modified porcine factor VIII are disclosed. The particular modified porcine factor VIII is one in which most of the B domain has been removed through genetic engineering. This modified factor VIII is particularly useful for treatment of hemophiliacs, especially those undergoing bleeding episodes.

Abstract: Methods and compositions are provided that allow for high-level expression of a factor VIII polypeptide. More specifically, methods and compositions are provided comprising nucleic acid and amino acid sequences comprising a modified factor VIII that result in high-level expression of the polypeptide. The methods and compositions of the invention find use in the treatment of factor VIII deficiency including, for example, hemophilia A.

Abstract: Specific amino acid loci of human factor VIII interact with inhibitory antibodies of hemophilia patients who have developed such antibodies after being treated with factor VIII. Modified factor VIII is disclosed in which the amino acid sequence is changed by a substitution at one or more of the specific loci. The modified factor VIII is not inhibited by inhibitory antibodies against the A2 or C2 domain epitopes. The modified factor VIII is useful for hemophiliacs, either to avoid or prevent the action of inhibitory antibodies.

Abstract: Specific amino acid loci of human factor VIII interact with inhibitory antibodies of hemophilia patients who have developed such antibodies after being treated with factor VIII. Modified factor VIII is disclosed in which the amino acid sequence is changed by a substitution at one or more amino acids of positions 484-508 of the A2 domain. The modified factor VIII is useful as a clotting factor supplement for hemophiliacs.
