It has been previously demonstrated that glypican-3 (GPC3) is differentially expressed in hepatocellular carcinomas (HCC), making it a promising target for radiopharmaceutical therapy to treat HCC. At the ongoing meeting of the European Association of Nuclear Medicine in Vienna, researchers from Rayzebio Inc. and Peptidream Inc. presented the preclinical characterization of a novel proprietary peptide binder of GPC3, RAYZ-8009.
