1. A therapeutic composition, comprising a pharmaceutically-acceptable carrier and at least one antibody or antigen-binding fragment thereof that specifically binds to a human neuropilin-2 (NRP2) polypeptide at an epitope in the neuropilin a2 domain of human NRP2, wherein the at least one antibody or antigen-binding fragment thereof comprises:
a heavy chain variable region (VH) sequence that comprises complementary determining region VHCDR1, VHCDR2, and VHCDR3 sequences; and a light chain variable region (VL) sequence that comprises complementary determining region VLCDR1, VLCDR2, and VLCDR3 sequences, wherein:
the VHCDR1, VHCDR2, and VHCDR3 sequences comprise SEQ ID NOs: 31-33, respectively, and the VLCDR1, VLCDR2, and VLCDR3 sequences comprise SEQ ID NOs: 34-36, respectively; or
the VHCDR1, VHCDR2, and VHCDR3 sequences comprise SEQ ID NOs: 37-39, respectively, and the VLCDR1, VLCDR2, and VLCDR3 sequences comprise SEQ ID NOs: 40-42, respectively,
including variants thereof that differ by substitution of one amino acid in VHCDR3, VLCDR1 and/or VLCDR3, wherein the VHCDR3 sequence comprises SEQ ID NO: 81, the VLCDR1 sequence comprises SEQ ID NO: 82, and the VLCDR3 sequence comprises SEQ ID NO: 83, wherein X5 of SEQ ID NO: 83 is F, G, I, K, L, N, R, T, V, or Y.
