BINDING FUSION PROTEINS, BINDING FUSION PROTEIN-DRUG CONJUGATES, XTEN-DRUG CONJUGATES AND METHODS OF MAKING AND USING SAME
The present invention relates to binding fusion protein compositions comprising targeting moieties linked to extended recombinant polypeptide (XTEN), binding fusion protein-drug conjugate compositions, and XTEN-drug conjugate compositions, isolated nucleic acids encoding the compositions and vectors and host cells containing the same, and methods of using such compositions in treatment of diseases, disorders, and conditions.
1 . An isolated binding fusion protein comprising a first extended recombinant polypeptide (XTEN) comprising at least 36 amino acid residues and a first targeting moiety with specific binding affinity to a first target, wherein said fusion protein exhibits a terminal half-life that is longer than about 72 hours when administered to a subject.
