Factor VIII polymer conjugates
View Patent ↗The invention is a proteinaceous construct comprising a Factor VIII molecule which is conjugated to a water-soluble polymer via carbohydrate moieties of Factor VIII, and methods of preparing same.
1. A kit comprising a pharmaceutical composition comprising (i) a Factor VIII molecule wherein at least one water soluble polymer is bound to said Factor VIII molecule, wherein said water soluble polymer is attached to the Factor VIII via one or more carbohydrate moieties located in the B domain of Factor VIII, wherein said molecule retains at least 50% of native FVIII activity, and (ii) a pharmaceutically acceptable excipient; packaged in a container with a label that describes use of the pharmaceutical composition.
2. A kit comprising a first container comprising a Factor VIII molecule wherein at least one water soluble polymer is bound to said Factor VIII molecule, wherein said water soluble polymer is attached to the Factor VIII via one or more carbohydrate moieties located in the B domain of Factor VIII, wherein said molecule retains at least 50% of native FVIII activity, and a second container comprising a physiologically acceptable reconstitution solution for said conjugate in the first container, wherein said kit is packaged with a label that describes use of the pharmaceutical composition.
