lutetium Lu 177-DOTA-octreotate
A radioconjugate consisting of the somatostatin analog octreotate labeled with lutetium Lu 177 with receptor ligand, beta-emitting radioisotope, and potential antineoplastic activities. Lutetium Lu 177-DOTA-octreotate binds to somatostatin receptors (SSTRs), especially type 2 receptors, present on the cell membranes of many types of neuroendocrine tumor cells. Upon binding and internalization, this radioconjugate specifically delivers a cytotoxic dose of beta radiation to SSTR-positive cells. Lutetium Lu 177-DOTA-octreotate is produced by substituting the natural amino acid Thr for the alcohol Thr(ol) at the C terminus of the somatostatin analog octreotide and chelating the octreotate to Lu 177 via dodecanetetraacetic acid (DOTA). Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus)
