Abrégé
Disclosed herein are a novel antibody and an antigen binding fragment thereof that targets CD30 to treat cancer, a chimeric antigen receptor, and a use thereof. The antibody, which binds specifically to CD30 that is highly expressed in cancer cells (specifically blood cancer), is very low in sequence homology with the CDR sequences of conventional CD30 targeting antibodies and thus has a unique sequence. Cells that express the chimeric antigen receptor including the anti-CD30 antibody or the antigen binding fragment responds to CD30-expressing positive cells to induce immune cell activity, thus finding advantageous applications as a CAR-immune cell product.

The present disclosure relates to complex comprising an engineered polypeptide having affinity for interleukin-6 (in the following referred to as IL-6) and an antibody or an antigen binding fragment thereof, wherein said engineered polypeptide having affinity for IL-6 belongs to a class of engineered polypeptides comprising the sequence EEX3X4AWX7EIHX11 LPNLX16X17X18QX20X21AFIX25X26LX28X29. The present disclosure also relates to the use of said complex as a therapeutic agent.

The present invention relates to a novel HER2 antibody for concomitant administration which is used for preventing or treating cancer. The antibody of the present invention specifically binds to HER2, which is overexpressed in cancer cells (particularly, breast cancer and gastric cancer cells), and binds to an epitope different from that to which trastuzumab binds. The antibody of the present invention has a unique sequence due to a very low homology compared with the CDR sequence of known HER2-targeting antibodies. The antibody of the present invention kills cancer cells with remarkably improved cancer cell killing ability when concomitantly administered with trastuzumab, and is thus very useful for preventing or treating cancer (particularly, breast cancer and gastric cancer). The remarkable efficacy of concomitant administration of the antibody of the present invention is considered, without wishing to be bound by theory, to be due to the antibody of the present invention binding to an epitope of HER2 different from that to which trastuzumab binds, thereby inhibiting HER2 cooperatively with trastuzumab.
