Abstract

The disclosure provides fusion polypeptides comprising a moiety specific for Ang-2 and another for VEGF-A, which fusion polypeptide can be useful for antagonizing Ang-2 and VEGF-A. In a preferred embodiment, the Ang-2-specific moiety is comprised of a human neutrophil gelatinase associated lipocalin (hNGAL) mutein. Such fusion polypeptide can be used in many pharmaceutical applications, for example, as an agent useful to inhibit or reduce angiogenesis. The present disclosure also concerns methods of making the fusion polypeptides described herein as well as compositions comprising such fusion polypeptides. The present disclosure further relates to nucleic acid molecules encoding such fusion polypeptides, their amino acid sequences and to methods for the generation of such fusion polypeptides and nucleic acid molecules. In addition, the application discloses therapeutic and/or diagnostic uses of such fusion polypeptide as well as compositions comprising one or more of such fusion polypeptides.
