1. A method of inducing trogocytosis from a donor cancer cell that expresses EGFR, c-Met, or EGFR and c-Met to an acceptor macrophage cell or an acceptor monocyte cell, the method comprising contacting the donor cancer cell with a bispecific anti-EGFR/c-Met antibody for a time sufficient to induce trogocytosis from the donor cancer cell to the acceptor macrophage cell or the acceptor monocyte cell,
wherein the bispecific anti-EGFR/c-Met antibody comprises:
a first domain that binds EGFR, wherein the first domain comprises a heavy chain complementarity determining region (HCDR1) comprising the amino acid sequence of SEQ ID NO: 1, a HCDR2 comprising the amino acid sequence of SEQ ID NO: 2, a HCDR3 comprising the amino acid sequence of SEQ ID NO: 3, a light chain complementarity determining region 1 (LCDR1) comprising the amino acid sequence of SEQ ID NO: 4, a LCDR2 comprising the amino acid sequence of SEQ ID NO: 5, and a LCDR3 comprising the amino acid sequence of SEQ ID NO: 6; and
a second domain that binds c-Met, wherein the second domain comprises a HCDR1 comprising the amino acid sequence of SEQ ID NO: 7, a HCDR2 comprising the amino acid sequence of SEQ ID NO: 8, a HCDR3 comprising the amino acid sequence of SEQ ID NO: 9, a LCDR1 comprising the amino acid sequence of SEQ ID NO: 10, a LCDR2 comprising the amino acid sequence of SEQ ID NO: 11, and a LCDR3 comprising the amino acid sequence of SEQ ID NO: 12.
