Definition

An unlabeled radiotracer composed of the human prostate specific membrane antigen (PSMA)-targeting ligand and linked to the acyclic radiometal chelator N,N’-bis [2-hydroxy-5-(carboxyethyl)benzyl] ethylenediamine-N,N’-diacetic acid (HBED-CC), that may potentially be used to prevent or reduce salivary gland toxicities of PSMA-targeted radionuclides. Upon administration of gozetotide into the salivary gland, gozetotide may selectively decrease salivary uptake of systemically administered PSMA-targeted radionuclides. This may reduce the salivary gland toxicities of these agents including salivary gland hypofunction and xerostomia.
