Abstract: Provided are an anti-CD40 antibody, an antigen binding fragment thereof, and a medical use thereof. Also provided are a chimeric antibody and a humanized antibody including a CDR region of the anti-CD40 antibody, a pharmaceutical composition including the human anti-CD40 antibody and the antigen binding fragment thereof, and an application thereof as an anti-cancer drug. In particular, provided are a humanized anti-CD40 antibody, and an application thereof in preparation of a drug to treat a CD40-mediated disease or disorder.

Abstract: The present invention relates to an anti-CD40 antibody, an antigen binding fragment and a pharmaceutical use thereof. Heavy-chain constant regions of the anti-CD40 antibody and the antigen binding fragment thereof contain mutations. Due to the mutations, the anti-CD40 antibody loses the binding activity to Fc?RIII, and the binding of the anti-CD40 antibody and Fc?RIIB is enhanced, thereby losing the antibody-dependent cytotoxicity (ADCC) but improving Fc?RIIB-mediated antibody crosslinking. The mutations in the heavy-chain constant regions enhance the activation of CD40, and enhance the presentation of dendritic cells to antigens. The anti-CD40 antibody and the antigen binding fragment thereof can be used as anti-cancer drugs to treat CD40-mediated diseases or symptoms.
