Abstract
High-affinity antibodies recognizing Programmed Death Ligand-1 (PD-1) and Lymphocyte Activation Gene 3 protein (LAG-3) are disclosed. Binding sites from humanized anti-PD-1 and anti-LAG-3 antibodies are incorporated into a Fabs-in-Tandem Immunoglobulin format without significant loss of binding affinity, and the resultant bispecific, multivalent binding proteins are able to bind to both PD-1 and LAG-3 simultaneously. Such bispecific FIT-Ig binding proteins are useful for treatment of cancer.
