Amatuximab  (Synonyms: MORab-009)

Amatuximab (MORab-009) is a chimeric, humanized IgG1/k MAb that targets the cell surface mesothelin (MSLN). Mesothelin is a glycosylphosphatidyl inositol (GPI)-anchored membrane glycoprotein, which is present in a restricted set of normal adult tissues such as the mesothelium^[1][2].

Chimeric

Amatuximab (MORAb-009) is a mouse-human chimeric monoclonal antibody with a selective affinity for MSLN. In vitro, amatuximab elicits antibody-dependent cellular cytotoxicity (ADCC) against mesothelin expressing tumor cell lines and inhibits heterotypic cell adhesion of mesothelin-positive tumor cells to CA125-expressing tumor cells^[1].

In tumor xenograft studies, combination treatment with amatuximab plus chemotherapy led to a greater reduction in the growth of mesothelin-expressing tumors than either Amatuximab or chemotherapy alone^[1].
