Lutetium Lu 177 dotatate
DCTPepD ID DCTPepD0013
Active Ingredients Lutetium Lu 177 dotatate
Description A radioconjugate consisting of the tyrosine-containing somatostatin analog Tyr3-octreotate (TATE) conjugated with the bifunctional, macrocyclic chelating agent tetra-azacyclododecanetetra-acetic acid (DOTA) and radiolabeled with the beta-emitting radioisotope lutetium Lu 177, with potential imaging and antineoplastic activities. Lutetium Lu 177 dotatate belongs to an emerging form of treatments called Peptide Receptor Radionuclide Therapy (PRRT), which involves targeting tumours with molecules carrying radioactive particles that bind to specific receptors expressed by the tumour. Lutetium Lu 177 dotatate binds to somatostatin receptors (SSTRs), with high affinity to type 2 SSTR, present on the cell membranes of many types of neuroendocrine tumor (NET) cells. Upon binding and internalization, this radioconjugate specifically delivers a cytotoxic dose of beta radiation to SSTR-positive cells. Tyr3-octreotate (TATE) is an octreotide derivative in which phenylalanine at position 3 is substituted by tyrosine and position 8 threoninol is replaced with threonine. SSTRs have been shown to be present in large numbers on NET and their metastases, while most other normal tissues express low levels of SSTRs.
