NCIt definition : A radioconjugate composed of PSMA-R2, a human prostate-specific membrane antigen (PSMA)-targeting
ligand, conjugated to the beta-emitting radioisotope gallium Ga 68, with potential
imaging activity during positron emission topography/computed tomography (PET/CT).
Upon administration of gallium Ga 68 PSMA-R2, the PSMA-R2 moiety targets and binds
to PSMA-expressing tumor cells. This allows for visualization of PSMA-expressing cells
upon imaging. PSMA, a tumor-associated antigen (TAA) and type II transmembrane protein,
is expressed on the membrane of prostatic epithelial cells and overexpressed on the
majority of prostate tumor cells.;
