Abstract
The present disclosure relates to a novel anti-HER2 antibody or an antigen-binding fragment thereof used in the prevention or treatment of cancer, a chimeric antigen receptor including the same, and uses thereof. The antibody of the present disclosure is an antibody that specifically binds to HER2 which is highly expressed in cancer cells (particularly, breast cancer or gastric cancer cells), and binds to an epitope that is different from an epitope to which trastuzumab binds. When compared with trastuzumab, the antibody of the present disclosure exhibits better killing ability for HER2-unexpressed cancer cells which have non-reactivity (or resistance) to the trastuzumab antibody or have reduced sensitivity. In addition, when the anti-HER2 antibody of the present disclosure is administered in combination with trastuzumab, a synergistic killing ability is achieved for cancer cells on which the trastuzumab antibody acts. Therefore, a composition of the present disclosure can be very usefully used for combined administration with the trastuzumab antibody for the treatment of cancer, or for the treatment of cancer not treated with trastuzumab.
