Abstract
Described is the use of a first antibody molecule that specifically binds FcγRIIb via its Fab region, but lacks Fc region or has reduced binding to Fcγ receptors via its Fc region, for use in combination with a second antibody molecule that specifically binds to a receptor present on an immune cell, wherein the immune cell is an immune cell that suppresses anti-cancer immunity, which second antibody molecule has an Fc region that binds to at least one activating Fcγ receptor, and wherein the binding of the second antibody molecule to the receptor on the immune cell causes depletion and/or deactivation of the immune cell 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.
