Abstract: Provided herein are polypeptides which include tenth fibronectin type III domains (10Fn3) that bind to glypican-3. Also provided are fusion molecules comprising a 10Fn3 domain that bind to glypican-3 for use in diagnostic and therapeutic applications. Glypican-3 10Fn3 drug conjugates are also provided.

Abstract: Fibronectin type III (10Fn3) binding domains having novel designs that are associated with reduced immunogenicity are provided. The application describes alternative 10Fn3 binding domains in which certain immunogenic regions are not modified when producing a binder in order to maintain recognition as a self antigen by the host organism. The application also describes 10Fn3 binding domains in which HLA anchor regions have been destroyed thereby reducing the immunogenic contribution of the adjoining region. Also provided are 10Fn3 domains having novel combinations of modified regions that can bind to a desired target with high affinity.

Abstract: Provided herein are proteins comprising a fibronectin based scaffold (FBS) domain, e.g., 10Fn3 molecules, that bind specifically to a target, and wherein the FBS domain is linked at its C-terminus to a region consisting of PmXn, wherein P is proline, X is any amino acid and wherein n is 0 or an integer that is at least 1 and m is an integer that is at least 1, and wherein the PmXn moiety provides an enhanced property to the FBS domain, e.g., enhanced stability, relative to the protein that is not linked to the PmXn moiety.
