45 results about "Blood coagulation factor XIII" patented technology

The present invention relates to variants of a vitamin K-dependent serine protease of the coagulation cascade, preferably variants of factor IX (F.IX), wherein the variant is characterized in that it has clotting activity in absence of its cofactor. The present invention furthermore relates to the use of these variants for the treatment and / or prophylaxis of bleeding disorders, in particular hemophilia A and / or hemophilia B or hemophilia caused or complicated by inhibitory antibodies to F.VIII. The present invention also relates to further variants of factor IX (F.IX) which have desired properties and can, thus be tailored for respective specific therapeutic applications.

The invention relates to a method for determining a factor XIII deficiency, a method for determining a fibrinogen deficiency, and a method for differentiating between a factor XIII deficiency and a fibrinogen deficiency by means of thrombelastographic techniques. On the basis of the evaluation of the thrombelastographic parameters, a rapid and a selective substitution of factor XIII and / or of fibrinogen in deficiency states is possible.

The invention provides a preparation method for fibrinogen with the advantages of high dissolution rate in the production process, short production period, fast solubility in clinical use, good biological activity, high safety in clinical use and high yield. An aid is added into supernate anticoagulant plasma. Compared with the prior art, the preparation method has the advantages that: 1, the preparation method provided by the invention is high in extraction efficiency; 2, the aid adopted in the method can improve the quality of the fibrinogen product, and plays a role in protecting the biological activities of the fibrinogen and blood coagulation factors XIII in virus inactivation and cold ethanol settlement processes; 3, in the process, the process solubility time of the fibrinogen is shortened to about 10 minutes; and 4, the solubility time of the freeze dried product of the fibrinogen is within 30 seconds, so precious time is won for rescuing patients in time in clinic.

The present invention relates to prophylactic dosing regimens with long-acting factor IX (FIX) in dosing intervals of 1 week or longer, including (but not limited to) 10 days or longer, such as two weeks, three weeks or even monthly.

A patient having hemophilia A is treated by administering factor XIII generally in conjunction with factor VIII or desmopressin.

Described herein are RPE cells engineered to secrete FVII proteins, as well as compositions, pharmaceutical formulations, and implantable devices comprising these engineered RPE cells, and methods of making and using them for treating patients suffering from hemophilia or FVII deficiency.

The present invention relates to modified Factor VIII molecules with reduced N-linked glycosylation and reduced immunogenicity. The invention also relates to methods of using modified Factor VIII molecules, for example, to treat patients afflicted with hemophilia.

The invention provides a method for separating a Factor VIII (FVIII) protein from a first composition comprising the FVIII protein, which contains at least the light chain of FVIII, and a von-Willebrand-Factor (vWF) protein which comprises at least the FVIII binding domain of vWF, wherein the FVIII protein can form a complex with the vWF protein, the method comprising the steps: contacting the first composition with an affinity resin comprising a ligand and a matrix, wherein the ligand has an affinity to the light chain of FVIII, and separating the affinity resin from the mixture to obtain a modified first composition and a second composition, wherein the second composition contains the affinity resin, and a complex of the FVIII protein and the vWF protein.
