1. A composition comprising (a) a first antibody and a second antibody, wherein the first antibody comprises a first antigen-binding region capable of binding to human CD37 and a first Fc region of a human IgG, and the second antibody comprises a second antigen-binding region capable of binding to human CD20 and a second Fc region of a human IgG, wherein both the first Fc region and the second Fc region comprise a substitution of an amino acid at a position corresponding to E430, E345 or S440 in human IgG1 when using the EU numbering system, with the proviso that the substitution in S440, if present, is S440Y or S440W, and (b) a carrier,
wherein the first antigen-binding region comprises a variable heavy chain (VH) region comprising CDR sequences HCDR1, HCDR2 and HCDR3 and a variable light chain (VL) region comprising CDR sequences LCDR1, LCDR2 and LCDR3 selected from the group consisting of:
a. SEQ ID NOs: 22, 23, and 24, respectively, and SEQ ID NO: 26, the sequence EAS, and SEQ ID NO: 27, respectively,
