NCIt definition : A proprietary conjugate of rituximab, a recombinant chimeric murine/human antibody
directed against the CD20 antigen, with potential antineoplastic activity. Upon administration
of the rituximab conjugate CON-4619, the rituximab moiety targets and binds to CD20,
a hydrophobic transmembrane protein located on normal pre-B and mature B lymphocytes.
Following binding, rituximab triggers a host cytotoxic immune response against CD20-positive
cells.;
