zirconium Zr 89-desferrioxamine B monoclonal antibody huJ591

Definition

A radioimmunoconjugate comprised of the recombinant humanized monoclonal antibody J591 against prostate-specific membrane antigen (PSMA) conjugated to chelator desferrioxamine B (DFO-B) and labeled with the radioisotope zirconium Zr 89 with potential imaging property used in positron emission tomography (PET) imaging. Upon administration of zirconium Zr 89-desferrioxamine B monoclonal antibody huJ591, the antibody moiety binds to the extracellular domain of PSMA, and the radioisotope moiety may be detected using PET, thereby allowing the imaging and quantification of PSMA-expressing tumor cells. PSMA, or folate hydrolase is a cell surface peptidase highly expressed by malignant prostate epithelial cells and vascular endothelial cells of numerous solid tumor malignancies. In addition, upon PET imaging this agent provides high tumor:background tissue ratios.
