  • Patent number: 10836830
    Abstract: The present disclosure provides multispecific (e.g., bispecific) antibodies that specifically bind to human GITR and/or human OX40 as well as compositions comprising such antibodies. In a specific aspect, the multispecific antibodies specifically bind to human GITR and OX40 and modulate GITR and/or OX40 activity, e.g., enhance, activate, or induce GITR and/or OX40 activity, or reduce, deactivate, or inhibit GITR and/or OX40 activity. The present disclosure also provides methods for treating disorders, such as cancer, by administering a multispecific antibody that specifically binds to human GITR and/or OX40 and modulates GITR and/or OX40 activity, e.g., enhances, activates, or induces GITR and/or OX40 activity. Also provided are methods for treating autoimmune or inflammatory diseases or disorders, by administering a multispecific antibody that specifically binds to human GITR and/or OX40 and modulates GITR and/or OX40 activity, e.g., reduces, deactivates, or inhibits GITR and/or OX40 activity.
