anti-CD73 monoclonal antibody NZV930
A fully human monoclonal antibody targeting the ectoenzyme 5'-ecto-nucleotidase (cluster of differentiation 73; CD73; 5'-NT; ecto-5'-nucleotidase; NT5E), with potential immunomodulating and antineoplastic activities. Upon intravenous administration, anti-CD73 monoclonal antibody NZV930 targets and binds to CD73 on tumor cells, leading to internalization of CD73. This prevents CD73-mediated conversion of extracellular adenosine monophosphate (AMP) to adenosine, thereby preventing adenosine-mediated suppression of lymphocyte activity and increasing the activity of cytotoxic T lymphocytes (CTLs). This also activates macrophages and reduces the activity of both myeloid-derived suppressor cells (MDSCs) and regulatory T lymphocytes. By abrogating the inhibitory effect on the immune system and enhancing the CTL-mediated immune response against cancer cells, tumor cell growth is decreased. CD73, a plasma membrane protein belonging to the 5'-nucleotidase (NTase) family, is upregulated in many cancer cell types and catalyzes the conversion of extracellular nucleotides, such as AMP, to membrane-permeable nucleosides, such as adenosine; it plays a key role in adenosine-mediated immunosuppression within the tumor microenvironment.
