Abstract: Described herein are proteins comprising an Fc region or the like, such as monoclonal, bispecific and multispecific antibodies, wherein the Fc region has been modified to eliminate or strongly reduce Fc-mediated effector functions, while at the same time allow for good developability, for therapeutic purposes and where such effector functions are undesired.

Abstract: The present disclosure relates to antibodies having the ability to bind to the immune checkpoint protein programmed death-1 (PD-1), such as human PD-1, or nucleic acids encoding such antibodies, wherein the antibodies comprise modifications in the Fc region eliminating or reducing a Fc-mediated effector function of the antibodies. The present disclosure also relates to compositions or kits comprising said antibodies or nucleic acids, as well as to the use of these antibodies or nucleic acids or compositions in the field of medicine, preferably in the field of immunotherapy, e.g., for the treatment of cancers. The present invention further relates to methods for inducing an immune response in a subject comprising providing to the subject an antibody of the present disclosure or one or more nucleic acids encoding such an antibody, or a composition comprising said antibody or nucleic acids.

Abstract: The present invention provides a binding agent that binds to EpCAM and to CD137 which is useful to treat or prevent a tumor or cancer, or to prevent progression of a tumor or cancer.

Abstract: Provided herein are combinations of first and second antibodies having modified Fc effector functions resulting from amino acid substitutions in the Fc region, the amino acid substitutions allow for co-dependent activation of effector functions such as CDC and/or ADCC. Also provided are combinations of first and second antibodies having agonistic activity or enhanced agonistic activity resulting from amino acid substitutions in the Fc region where the agonistic activity is co-dependent of both a first and second antibodies.
