Gozetotide

**Semantic type:** Pharmacologic Substance

**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.

**Synonyms:** - (3S,7S)-22-(3-(((2-((5-(2-Carboxyethyl)-2-hydroxybenzyl)(carboxymethyl)amino)ethyl)(carboxymethyl)amino)methyl)-4-hydroxyphenyl)-5,13,20-trioxo-4,6,12,19-tetraazadocosane-1,3,7-tricarboxylic acid - GOZETOTIDE - PSMA-11 - PSMA-HBED-CC
