ARGX-111
Based on 1 Customer Validation
ARGX-111 is an anti-MET antibody. ARGX-111 blocks HGF-dependent and -independent signaling, downregulating MET expression on the tumor cell surface. ARGX-111 depletes MET-expressing circulating tumor cells through enhanced antibody-dependent cell-mediated cytotoxicity (ADCC), thereby inhibiting tumor metastasis. ARGX-111 depletes circulating tumor cells and inhibits bone and lung metastasis in an orthotopic mouse model of metastatic breast cancer. ARGX-111 is promising for research in breast cancer and other cancers.

Biological Activity
Human IgG1 lambda
Human
HGFR/c-Met
ARGX-111 binds to native MET with an EC50 ranging from 0.1 nmol/L to 0.7 nmol/L, competes with HGF displaying an IC50 of 1.3 nmol/L and an IMAX of 95%[1].
ARGX-111 inhibits HGF-induced MET autophosphorylation in A549 cells (IC50 = 5.3 nmol/L, IMAX = 74%), inhibits MET autophosphorylation in both MKN-45 cells (IC50 = 0.2 nmol/L, IMAX = 63%) and EBC-1 cells (IC50 = 12.7 nmol/L, IMAX = 69%)[1].
ARGX-111 neutralizes the promigratory effect of HGF, inhibits HGF-dependent colony formation by 78% in A549 cells[1].
ARGX-111 (1-10 nM/L) inhibits HGF-induced branched tubule formation in SV40 T-antigen-transformed LOC human kidney epithelial cell spheroids[1].
ARGX-111 (0.1-100 h) promotes a rapid decrease in MET expression in MKN-45, EBC-1 and MDA-MB 231 cells[1].
ARGX-111 (24-48 h) does not promote receptor shedding but reduced total MET protein levels in MKN-45 cells[1].
ARGX-111 (0-1000 nM/L) induces dose-dependent lysis in MKN-45, NCI-H441, A549 cells[1].
ARGX-111 induces antibody-dependent cellular phagocytosis (ADCP) in MKN-45 and 786-O cells[1].
ARGX-111 (0-667 nM/L) promotes dose-dependent ADCC in ALDH-1-sorted MDA-MB-231, CRCM168, CRCM174, CRCM389 cells[1].
