Described are novel antagonistic antibody molecules that specifically bind to TNFR2 on a target cell and thereby block TNF-α binding to TNFR2 and block TNFR2 signaling, wherein the antibody molecules also bind to Fc receptors via the Fc region. Also described is the use of such antibody molecules in treatment of cancer or infections caused by intracellular pathogens.

Antagonistic anti-TNFR2 antibodies

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.

Combination and use of antibodies

Description of a composition comprising an antibody molecule and an agent for use in the treatment of refractory cancer and/or relapsed cancer, and of a method of treating refractory cancer and/or relapsed cancer comprising administering an antibody molecule and an agent. There are also described kits comprising the antibody molecule and agents.

Medicaments, uses and methods

Described are novel anti-CTLA-4 antibody molecules and nucleotide sequences and expression vectors, such as viruses, encoding such antibody molecules. The novel antibody molecules are Treg depleting antibody molecules, and they have an improved depleting effect on CTLA-4 positive cells, such as Tregs, compared to ipilimumab. Described is also the use of such antibody molecules or nucleotide sequences or viruses in medicine, such as in the treatment of cancer, such as solid tumours.

Antibodies and nucleotide sequences, and uses thereof

Described are novel antibody molecules that specifically bind to TNFR2 on a target cell and thereby agonize TNFR2, but that do not block the ligand TNF-α from binding to the TNFR2. Also described is the use of such antibody molecules in medicine, i.a, in treatment of cancer or chronic inflammatory diseases.

Agonistic anti TNFR2 antibody molecules

Described is the sequential administration of first a Treg depleting antibody molecule selected from antibody molecules, such as an antibody molecule binding specifically to target belonging to the tumour necrosis factor receptor superfamily (TNFRSF), such as a Treg depleting anti-4-1 BB antibody or a Treg depleting OX-40 antibody, and then an immunostimulatory antibody molecule, such as an immunostimulatory anti-4-1 BB anti-body or an immunostimulatory OX-40 antibody, for use in the treatment of cancer. Described are also novel anti-4-1 BB antibodies and novel OX-40 antibodies that may be used in such sequential administration.

Combination of a Treg depleting anti-4-1BB antibody and anti-PD1 antibody

The invention provides binding molecules, including antibody molecules which selectively bind to a cell surface antigen of a target cell, and wherein the binding molecules, on binding the cell surface antigen, induce cell death of the target cell. There is also provided methods of and pharmaceutical compositions for cell death induction and uses thereof.
