PROBLEM TO BE SOLVED: To provide a dose and administration of a non-fucosylated anti-CD40 antibody. The present invention relates to methods of using non-fucosylated anti-CD40 antibodies to treat cancer and chronic infectious diseases. The anti-CD40 antibody may comprise a heavy chain variable region of SEQ ID NO: 1 and a light chain variable region of SEQ ID NO: 2, as well as a human constant region, said constant region being residue N297 according to the EU index shown in Kabat. In N., wherein less than 5% of the N-glycoside-linked sugar chains may contain fucose residues and is administered at a dose level between 0.1 and 2000 μg / kg of patient body weight. Can be done.
