According to certain embodiments, the present invention provides bispecific antigen-binding molecules comprising a first antigen-binding domain that specifically binds human CD3, a second antigen-binding molecule that specifically binds human CD20, and an Fc domain that binds Fc? receptors with a specific binding pattern. In certain embodiments, the bispecific antigen-binding molecules of the present invention are capable of inhibiting the growth of B-cell or melanoma tumors expressing CD20.

Abstract: The present invention provides antibodies that bind to the T cell co-inhibitor lymphocyte activation gene 3 (LAG3) protein, and methods of use. In various embodiments of the invention, the antibodies are fully human antibodies that specifically bind to LAG3. In some embodiments, the antibodies of the invention are useful for inhibiting or neutralizing LAG3 activity, thus providing a means of treating a disease or disorder such as cancer or viral infection.

Abstract: Anti-CD8 antibodies, radiolabeled anti-CD8 antibodies, fluorescently labeled anti-CD8 antibodies and their use in imaging are provided herein. Included are methods of detecting the presence of CD8 proteins in a subject or sample.

Abstract: This disclosure relates to novel triple combination therapies of an oncolytic virus, a PD-1 pathway inhibitor, and a CTLA4 inhibitor for treating or inhibiting the growth of a tumor in a patient with cancer.
