Abstract

Human epidermal growth factor receptor 2 (HER2) is reported to be overexpressed in breast cancers and is associated with poor clinical outcome. Trastuzumab is a humanized anti‑HER2 antibody that offers significant survival benefits to patients with HER2‑overexpressing breast cancer. In this study, a novel anti‑HER2 monoclonal antibody (mAb), H2Mab‑19 (IgG2b, kappa) was developed. Antibody‑dependent cellular cytotoxicity (ADCC), complement‑dependent cytotoxicity (CDC), and antitumor activity of H2Mab‑19 were investigated using both breast cancer and oral cancer cell lines. H2Mab‑19 demonstrated cytotoxicity in BT‑474 (a human breast cancer cell line) and HSC‑2 or SAS (human oral cancer cell lines). H2Mab‑19 also possessed both ADCC and CDC activity against BT‑474, HSC‑2, and SAS cell lines. In comparison to control mouse IgG, H2Mab‑19 significantly reduced tumor development in BT‑474, HSC‑2, and SAS xenografts. Collectively, these results suggest that treatment with H2Mab‑19 may be a useful therapy for patients with HER2‑expressing breast and oral cancers.
