CD3

Cluster of differentiation 3

CD3 (cluster of differentiation 3) is a protein complex and T cell co-receptor that is involved in activating both the cytotoxic T cell (CD8+ naive T cells) and T helper cells (CD4+ naive T cells). It is composed of four distinct chains. In mammals, the complex contains a CD3γ chain, a CD3δ chain, and two CD3ε chains. These chains associate with the T-cell receptor (TCR) and the CD3-zeta (ζ-chain) to generate an activation signal in T lymphocytes. The TCR, CD3-zeta, and the other CD3 molecules together constitute the TCR complex.

    Pacanalotamab
    Chemical
    Pacanalotamab (AMG 420; BI-836909) is a bispecific T-cell engager (BiTE) targeting to BCMA and CD3ɛ. BCMA refers to B cell maturation antigen, as Pacanalotamab redirecting T cells to BCMA expressing cells on the cell surface. Pacanalotamab conducts T-cell redirected lysis of human multiple myeloma (MM) cell lines.

    Tepoditamab
    Tepoditamab (MCLA-117) is a bispecific monoclonal antibody that binds to CLEC12A of myeloid cells and CD3 of cytotoxic T cells. Among others, CLEC12A is a myeloid differentiation antigen. Tepoditamab (MCLA-117) kills AML leukaemia mother cells and AML leukaemia stem cells, induces T cell-mediated proliferative lysis of AML cells and can be used in acute myeloid leukaemia (AML) research.

    Flotetuzumab
    98.71%
    Flotetuzumab (MGD006; S80880) is an investigational CD123/CD3 bispecific dual-affinity retargeting antibody (DART) molecule. Flotetuzumab reactivates T cells by simultaneously binding to CD123 in target cells and CD3 in effector T cells, leading to T-cell-mediated cytotoxicity in target cells. Flotetuzumab shows inhibitory effect on a mouse model of patient-derived xenograft (PDX) in acute myeloid leukemia (AML).
