anti-CD123/CD3 bispecific antibody JNJ-63709178
A humanized anti-CD123/anti-CD3 bispecific monoclonal antibody, with potential immunostimulating and antineoplastic activities. Anti-CD123/CD3 bispecific antibody JNJ-63709178 possesses two antigen-recognition and binding sites, one for the CD3 complex, a group of T-cell surface glycoproteins that complex with the T-cell receptor (TCR), and one for CD123, a tumor-associated antigen (TAA) overexpressed on the surface of certain tumor cells. Upon administration of JNJ-63709178, this bispecific antibody simultaneously binds to both CD3-expressing T cells and CD123-expressing cancer cells, thereby crosslinking CD123-expressing tumor cells and cytotoxic T lymphocytes (CTLs). This may result in potent CTL-mediated cell lysis of CD123-expressing tumor cells. CD123, the interleukin-3 receptor alpha chain, is overexpressed in a variety of cancers; its expression is low or absent in normal, healthy cells. Check for active clinical trials using this agent.
