Abstract:
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.
Abstract:
The present invention provides a modified polypeptide which binds Factor VIII. The polypeptide comprises truncated von Willebrand Factor (VWF) which comprises a sequence as shown in SEQ ID NO:3 or a fragment thereof or a sequence 90% identical thereto, wherein the truncated VWF comprises at least one modification in comparison to SEQ ID NO: 3 in at least one position selected from the group consisting of SI, S3, LI 8, V42, S43, K149, N248, S279, V320, T325, Q395 and K418.
Abstract translation:本发明提供了结合因子VIII的修饰多肽。 所述多肽包含截短的血管性血友病因子(VWF),其包含如SEQ ID NO:3中所示的序列或其片段或与其90%相同的序列,其中所述截短的VWF包含与SEQ ID NO: 3在选自由S1,S3,L1 8,V42,S43,K149,N248,S279,V320,T325,Q395和K418组成的组中的至少一个位置中。
Abstract:
The invention relates to materials and methods of conjugating a water soluble polymer to an oxidized carbohydrate moiety of a therapeutic protein comprising contacting the oxidized carbohydrate moiety with an activated water soluble polymer under conditions that allow conjugation. More specifically, the present invention relates to a modified, recombinant Factor VIII (FVIII) with extended half-life and reduced ligand-binding properties.
Abstract:
The present invention is in the field of gene therapy, particularly targeted delivery of transgene-encoding constructs to the liver for expression of beneficial (therapeutic) proteins. In particular, the invention relates to the treatment of hemophilias such as Hemophilia A. The present invention describes compositions and methods for expressing a transgene in a liver cell. The transgene may be expressed extrachromosomally (episomally) or may be integrated into the genome of the liver cell. In some embodiments, the transgene encodes a protein involved in the clotting cascade. In preferred embodiments, the transgene encodes a FVIII polypeptide.
Abstract:
The invention provides adeno-associated virus (AAV) Factor VIII (FVIII)- encoding/expressing vectors and virus, including AAV FVIII vectors with high expression activity and AAV FVIII vectors that express full-length or truncated functional FVIII protein. The invention also relates to methods of making the herein described AAV FVIII vectors, recombinant AAV FVIII virus particles comprising or expressing such vectors, associated pharmaceutical formulations comprising the same and therapeutic uses thereof.
Abstract:
Provided herein are methods for producing an adeno-associated virus (AAV) particle containing an oversized recombinant AAV genome (e.g., greater than 4.7 kb). In some aspects, the invention provides AAV particles and AAV vectors comprising oversized rAAV genomes. Producer cell lines to produce AAV particles comprising oversized genomes are also provided.
Abstract:
The present invention relates to nucleic acid expression cassettes and vectors containing liver- specific regulatory elements and codon-optimized factor IX or factor VIII transgenes, methods employing these expression cassettes and vectors and uses thereof. The present invention is particularly useful for applications using liver-directed gene therapy, in particular for the treatment of hemophilia A and B.
Abstract:
The invention relates to a compound, preferably an antibody, capable of binding to the receptor protein CLEC10A for use in the treatment of a blood coagulation disorder.
