Definition

A radioconjugate composed of 5G, an agent targeting an as of yet undisclosed target, conjugated, via the bifunctional, macrocyclic chelating agent 1,4,7,10-tetra-azacyclododecane-1,4,7,10-tetra-acetic acid (DOTA) and an albumin binding moiety (ABM), to the radioisotope lutetium Lu 177, with potential antineoplastic activity. Upon administration of lutetium Lu 177-DOTA-ABM-5G, the 5G moiety targets and binds to a specific target on tumor cells. Upon binding, lutetium Lu 177 delivers a cytotoxic dose of beta radiation to the tumor cells.
