Abstract: The present disclosure is related to compositions of antibodies and immunoconjugates that potentially lack T-cell epitopes and elicit reduced immune response. The antibody may be an antibody fragment, such as Fab, Fab?, F(ab?)2, scFv, dsFv, ds-scFv, dimers, minibodies, diabodies, bispecific antibody fragments, multimers, and any combination thereof. In a further embodiment, the antibody may bind to an antigen epithelial cell adhesion molecule (EpCAM). In another embodiment, an immunoconjugate may comprise an antibody attached to an effector molecule, wherein the effector molecule may be a radioisotope, an antineoplastic agent, an immunomodulator, a biological response modifier, lectin, a toxin, a chromophore, a fluorophore, a chemiluminescent compound, an enzyme, a metal ion, and any combination thereof.

Abstract: Disclosed herein are compositions and methods to treat hepatocellular carcinoma. In one embodiment, a method of treating a subject with hepatocellular carcinoma comprises administering a therapeutically effective amount of an immunoconjugate (VB4-845) comprising an antibody conjugated to an effector molecule, and wherein the antibody recognizes epithelial cell adhesion molecule (Ep-CAM). The effector molecule may be Pseudomonas exotoxin A. In some embodiments, the immunoconjugate may be co-administered, concurrently administered, or sequentially administered with one or more other anticancer agents.
