lutetium Lu 177 AB-3PRGD2

A radiopharmaceutical agent comprised of a pegylated cyclic arginine-glycine-aspartic acid (RGD) dimer (PRGD2) labeled with lutetium Lu 177, with potential antineoplastic activity against alphaVbeta3 integrin-expressing tumor cells. Upon administration of lutetium Lu 177 AB-3PRGD2, the RGD moiety binds to alphaVbeta3 integrin on alphaVbeta3 integrin-expressing tumor cells. The tumor cells can be eradicated upon direct cytotoxicity through beta radiation. AlphaVbeta3 integrin, a member of the integrin receptor family, is overexpressed on certain tumor cells and tumor endothelial cells while minimally or not expressed on healthy, normal cells; this receptor plays a key role in angiogenesis, tumor proliferation and survival.
