To provide : antibody molecules having an improved therapeutic profile over known molecules, for therapeutic purposes in the field of cancer diseases; and nucleic acid molecules encoding the antibody molecules, expression vectors, host cells, and methods of making the antibody molecules.SOLUTION : The present invention relates to novel anti-PD1 and anti-LAG3 antibody molecules, and to compositions comprising the antibody molecules. The anti-LAG3 antibody molecules demonstrate better activation of T cells when used in combination with the anti-PD1 antibody molecules than reference anti-PD1 antibody molecules and anti-LAG3 antibody molecules.SELECTED DRAWING : None
