1. A method for inhibiting, delaying or reducing tumor growth in a subject with cancer, comprising administering to the subject a combination of an effective amount of an isolated antibody or antigen-binding fragment thereof that specifically binds to semaphorin-4D (SEMA4D) and an effective amount of an anti-Lymphocyte Activation Gene 3 (LAG-3) antibody or antigen-binding fragment thereof; or a combination of an effective amount of an isolated antibody or antigen-binding fragment thereof that specifically binds to semaphorin-4D (SEMA4D), an anti-LAG-3 antibody or antigen-binding fragment thereof, and another antibody or antigen-binding fragment thereof that inhibits an immune checkpoint blockade;
wherein the antibody or antigen-binding fragment thereof that specifically binds to SEMA4D comprises a variable heavy chain (VH) comprising VHCDRs 1-3 comprising SEQ ID NO: 6, 7, and 8, respectively, and a variable light chain (VL) comprising VLCDRs 1-3 comprising SEQ ID NO: 14, 15, and 16, respectively; and
wherein administration of the combination results in enhanced therapeutic efficacy relative to administration of the anti-SEMA4D antibody or the anti-LAG-3 antibody alone.
