摘要:
The invention provides vitamin k-dependent polypeptides with enhanced membrane binding affinity. These polypeptides can be used to modulate clot formation in mammals. Methods of modulating clot formation in mammals are also described.
摘要:
Nucleic acid constructs comprising procoagulant gene sequences under the control of a megakaryocyte-specific promoter are provided. The sequences preferably also comprise a secretory granule sorting domain Also provided are vectors comprising the sequences and methods of gene therapy comprising the use of the various constructs.
摘要:
A novel hemostatic composition and a hemostatic pharmaceutical preparation are provided. A pharmaceutically stable hemostatic liquid composition comprising a mixed solution of activated blood coagulation factor VII (FVIIa) and blood coagulation factor X (FX) in a single container. The mixed solution is maintained at pH ranging from 5.0 to 6.5.
摘要:
The present invention provides novel purified and isolated nucleic acid sequences encoding procoagulant-active FVIII proteins. The nucleic acid sequences of the present invention encode amino acid sequences corresponding to known human FVIII sequences, wherein residue Phe3O9 is mutated. The nucleic acid sequences of the present invention also encode amino acid sequences corresponding to known human FVIII sequences, wherein the APC cleavage sites, Arg336 and Ile562, are mutated. The nucleic acid sequences of the present invention further encode amino acid sequences corresponding to known human FVIII sequences, wherein the B-domain is deleted, the von Willebrand factor binding site is deleted, a thrombin cleavage site is mutated, an amino acid sequence spacer is inserted between the A2- and A3-domains. Methods of producing the FVIII proteins of the invention, nucleotide sequences encoding such proteins, pharmaceutical compositions containing the nucleotide sequences or proteins, as well as methods of treating patients suffering from hemophilia, are also provided.
摘要:
Use of factor XIII for treating hemophilia B. A patient having hemophilia B is treated by administering factor XIII generally in conjunction with factor IX.
摘要:
The present invention relates to a composition comprising factor VII or a factor VII-related poly-peptide and epsilon-aminocaproic acid, and the use thereof for treating bleeding episodes.
摘要:
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.
摘要:
The present invention relates to the use of factor VIIa and TFPI inhibitor in the treatment or prophylaxis of bleeding episodes or coagulative treatment.
摘要:
There are disclosed a stable factor VIII/vWF-complex, particularly comprising high-molecular vWF multimers, being free from low-molecular vWF molecules and from proteolytic vWF degradation products, as well as a method of producing this complex.
摘要:
Composition and methods are described for low immunogenic protein formulations. An example of such a protein is antihemophilic factor (FVIII). The composition generally includes the protein, polypeptide or peptide, one or more agents that bind to epitope domains of the proteins to form a complex. Buffers containing salts may be used to stabilize this interaction. For example, Factor VIII and serine containing phospholipids in buffer salts containing Ca2null and Nanull can be used to prepare protein-lipid structures. These complexes are useful for treatment of diseases such as Hemophilia. A method for the formation of novel non-liposomal structures is also disclosed.
