NCIt definition : A humanized immunoglobulin G2 (IgG2) monoclonal antibody directed against CD147 (basigin;
BSG; extracellular matrix metalloproteinase inducer; EMMPRIN), with potential immunomodulating
activity. Upon administration, meplazumab targets, binds to and inhibits the activity
of CD147. This may prevent the binding of the spike protein (SP) of SARS-CoV-2 to
CD147 on human host cells. This may prevent SARS-CoV-2's host cell entry through CD147-mediated
transport and prevent host cell invasion. This may block SARS-CoV-2 infection. In
addition, preventing viral invasion of progenitor/stem cells may enhance lung repair
and suppress inflammation. CD147, a highly glycosylated transmembrane protein of the
immunoglobulin superfamily expressed on host-cells, including red blood cells (RBCs),
T-cells, and stem/progenitor cells, may play a key role in host invasion by SARS-CoV-2.;
