ErbB-1

Trastuzumab is a humanized monoclonal antibody for patients with invasive breast cancers that overexpress HER2. Trastuzumab has been clinically used to treat HER2 Positive Metastatic Breast Cancer and HER2 Positive Gastric Cancer.

Cetuximab (C225) is a monoclonal antibody that is an inhibitor of human epidermal growth factor receptor (EGFR) (Kd=0.201 nM). Cetuximab has antitumor activity, inhibiting tumor cell proliferation and inducing apoptosis.

Panitumumab is a fully human IgG2 monoclonal antibody targeting the epidermal growth factor receptor EGFR).

Matuzumab (EMD 72000) is a humanized monoclonal antibody targeting EGFR with potential anticancer activity that blocks EGFR activation and downstream signaling for the study of non-small cell lung cancer.

MP-RM-1 is a selective murine monoclonal antibody inhibitor that targets the human epidermal growth factor receptor 3 (ErbB-3). It blocks ErbB-3 activation induced by neuregulin 1 (NRG-1β), facilitates ErbB-3 internalization and degradation, and inhibits downstream signaling pathways like PI3K-Akt. MP-RM-1 shows potential for research on ErbB-3-overexpressing solid tumors such as breast cancer, melanoma, and prostate cancer.
