Abstract: The present invention provides various CD40 binding molecules (including, but not limited to, antibodies), compositions comprising such CD40 binding molecules, and methods of using such CD40 binding molecules and compositions, for example for CD40-mediated activation of cells, such as antigen presenting cells.

Abstract: The present invention provides various compositions and methods useful for the treatment of cancer, such as cancers that are resistant to immune checkpoint blockade and/or are resistant to treatment with PD-1, PD-L1 or CTLA-4 inhibitors. In some embodiments the present invention provides compositions comprising one or more CD40 agonists (e.g. CD40 agonist antibodies), TLR agonists, and/or IL10 receptor inhibitors or IL10 inhibitors, and/or various combinations thereof, optionally together with one or more immune checkpoint inhibitors, and the use of such compositions in treatment of tumors.

Abstract: The present invention provides various compositions and methods useful for the treatment of cancer, including, but not limited to, cancers that are resistant to immune checkpoint blockade and/or are resistant to treatment with PD-1, PD-L1 or CTLA-4 inhibitors. In some embodiments the present invention provides compositions comprising “bi-specific activators”—which are nanoparticles having both a CD40 agonist antibody and an antibody specific for a tumor-associated antigen on their surface. In some embodiments such nanoparticles comprise one or more vaccine adjuvants, for example inside the nanoparticles. The present invention also relates to the use of such compositions in the treatment of tumors.
