NCIt definition : Monoclonal recombinant antibody J591 (mAb HuJ591) recognizes the extracellular domain
of prostate specific membrane antigen (PSMA), a cell surface peptidase highly expressed
by malignant prostate epithelial cells and vascular endothelial cells of numerous
solid tumor malignancies. Early results of clinical Phase I and II studies indicate
that mAb HuJ591 represents targeted therapy to PSMA and has therapeutic potential
in disseminated prostate cancer and other urological and solid tumor malignancies
and did not result in a host immune response to the antibody. (NCI);
