lutetium Lu 177 satoreotide tetraxetan

A radioconjugate consisting of the somatostatin antagonistic peptide satoreotide tetraxetan (JR11) that is linked, via the chelating agent dodecanetetraacetic acid (DOTA), to the beta-emitting radioisotope lutetium Lu 177, with potential antineoplastic activity and imaging activity during positron emission tomography/computed tomography (PET/CT). Upon administration, lutetium Lu 177-DOTA-JR11 binds to somatostatin receptors (SSTRs), with high affinity for SSTR2, 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. SSTRs have been shown to be present in large numbers on NETs and their metastases, while most normal tissues express low levels of SSTRs.
