Combination of a fcyrllb- and a tumor antibody for use in the treatment of an fcyriib-negative cancer

Described is the use of a first antibody molecule that specifically binds Fc RIIB via its Fab region, but lacks Fc region or has reduced binding to Fc receptors via its Fc region, for use in combination with a second antibody molecule that specifically binds to a receptor present on a tumor cell, wh...

Zusammenfassung:Described is the use of a first antibody molecule that specifically binds Fc RIIB via its Fab region, but lacks Fc region or has reduced binding to Fc receptors via its Fc region, for use in combination with a second antibody molecule that specifically binds to a receptor present on a tumor cell, which second antibody molecule has an Fc region that binds to at least one activating Fc receptor in the treatment of an FcγRIIB-negative cancer in a patient, as well as pharmaceutical compositions and kits comprising these to antibody molecules, and methods of treating cancer using these two antibodies.
