Anti-TM4SF1 antibodies, and antigen-binding fragments thereof, are described that bind to an epitope on the ECL2 loop of human TM4SF1. Methods of use of said antibodies and fragments are also described, including for the inhibition of metastasis.

Anti-TM4SF1 antibodies and methods of using same

This present invention relates to compounds (e.g., TM4SF1 binding proteins, e.g., anti-TM4SF1 antibodies) that specifically bind to a polypeptide at an epitope including an amino acid sequence of SEQ ID NO: 1. In particular, the compounds of the invention are capable of being internalized into a TM4SF1-expressing cell (e.g., a tumor cell or an angiogenic vasculature endothelial cell) following binding to the epitope of including the amino acid sequence of SEQ ID NO: 1. The invention also provides methods of treating a subject having a disorder associated with pathological angiogenesis with the compounds of the invention.

TM4SF1 binding proteins and methods of using same

The present invention provides an immunological preparation comprising not less than two types of conjugate molecules in admixture for concurrent specific binding to a spatially exposed region of vascular permeability factor (VPF) bound in-vivo to a tumor-associated blood vessel. Each conjugate molecule type comprises at least a binding portion of an antibody specific for an epitope present within a spatially exposed region of bound VPF; and an effector moiety covalently bound to the specific binding portion. The immunological preparation has wide uses and applications including analytical studies, in-vivo diagnostic testing, and in-vivo therapeutic treatments.

Immunological preparation for concurrent specific binding to spatially

New compounds that bind specifically to vascular permeability factor (VPF) are used in methods of targeting these compounds, which include effector molecules that are, e.g., toxic, radioactive, or serve as marker labels, for tumor cells and the associated blood vessel endothelial cells, based on the discovery that VPF concentrates selectively in the endothelium and basement membrane lining tumor-associated blood vessels to a far greater degree than in normal vessels. By targeting VPF rather than the tumor cells themselves, the invention avoids the problems of tumor heterogeneity and diffusion distance.
