anti-SSTR2/CD3 monoclonal antibody XmAb18087

A humanized, Fc domain-containing, bispecific monoclonal antibody targeting human CD3, a T-cell surface antigen, and somatostatin receptor 2 (SSTR2), a tumor-associated antigen (TAA) expressed on certain cancer cells, with potential antineoplastic activity. Upon administration, anti-SSTR2/CD3 monoclonal antibody XmAb18087 binds to both T cells and SSTR2-expressing cancer cells. The resulting cross-linkage may trigger a potent cytotoxic T-lymphocyte (CTL) response against the SSTR2-expressing cancer cells. The inclusion of an Fc domain on the antibody prolongs the half-life of the bispecific antibody.
