rituximab conjugate CON-4619

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.
