Provided is a monoclonal antibody 11G01 combing and inhibiting activation of epidermal growth factor relevant members Erbb3/HER3. The KD value of 11G01 to ERBB3 is 55 pM. The antibody can be used for treating study of the esophagus cancer.
Figure 1A-1B are graphs summarizing results from an experiment to measure the neutralization activity of negative control (murine IgG (Δ)) and anti-ErbB3 monoclonal antibodies 04D01 (▪), 12A07 (◯), 18H02 (▯), 22A02 (□) and 24C05 (Q) to inhibit NRG1-β1 binding to hErbB3 (Figure 1A) and to measure the enhanced binding of NRG1-β1 to rhErbB3 by the anti-ErbB3 mAb 09D03 (▴) and 11G01 (*) (Figure 1B).
Figure 2 is a graph summarizing results from an experiment to measure the neutralization activity of negative control (murine IgG) and anti-ErbB3 monoclonal antibodies 04D01, 09D03, 11G01, 12A07, 18H02, 22A02 and 24C05 to inhibit NRG1-al binding to rhErbB3.
Figure 3 is a graph summarizing results from an experiment to measure the anti-proliferation activity of negative control IgG (murine IgG (Δ)) and anti-ErbB3 monoclonal antibodies 04D01 (▪), 09D03 (▾), 11G01 (♦), 12A07 (◯), 18H02 (⋄), 22A02 (▯) and 24C05 (□) in BaF/3 cells expressing Her2 and ErbB3 in presence of NRG1-β1.
Figure 4 is a graph summarizing results from an experiment to measure the anti-proliferation activity of anti-ErbB3 monoclonal antibodies 04D01 (▪), 09D03 (▾), 11G01 (♦), 12A07 (▪), 18H02 (⋄), 22A02 (▯) and 24C05 (□) in MCF7 cells in the presence of NRG1-β1.
Figure 5 is a graph summarizing results from an experiment to measure the tumor inhibitory activity of the anti-ErbB3 antibodies 04D01 (Δ), 09D03 (*), 11G01 (□), 12A07 (▴), 18H02 (▯), 22A02 (▪), 24C05 (◯) and a human IgG control (- -▪- -) dosed at 20 mg/kg in a BxPC3 pancreatic tumor xenograft model in CB 17 SCID mice (vehicle control, PBS (♦)).
