Lutetium Lu 177 NYM032

**Semantic type:** Pharmacologic Substance

**Definition:** A radioconjugate composed of NYM032, a human prostate-specific membrane antigen (PSMA)-targeting ligand, conjugated to the beta-emitting radioisotope lutetium Lu 177 (177Lu), with potential antineoplastic activity against PSMA-expressing tumor cells. Upon intravenous administration, lutetium Lu 177 NYM032 targets and binds to PSMA-expressing tumor cells. Upon binding, PSMA-expressing tumor cells are destroyed by direct cytotoxicity through beta radiation. PSMA, a tumor-associated antigen (TAA) and type II transmembrane protein, is expressed on the membrane of prostatic epithelial cells and overexpressed on prostate tumor cells as well as a variety of other solid tumors.
