Abstract
Introduction: Glypican-3 (GPC3) is a cell membrane-anchored heparan sulfate proteoglycan that has recently garnered attention as a cancer antigen owing to its high expression in numerous cancers, particularly hepatocellular carcinoma (HCC), and to limited expression in adult normal tissue.
Areas covered: Here, we propose the potential of GPC3 as a cancer antigen based on our experience with the GPC3 peptide vaccine against HCC, having developed a vaccine that progressed from preclinical studies to first-in-human clinical trials. In this review, we present a summary of the current status and future prospects of immunotherapies targeting GPC3 by focusing on clinical trials; peptide vaccines, mRNA vaccines, antibody therapy, and chimeric antigen receptor/T-cell receptor - T-cell therapy and discuss additional strategies for effectively eliminating HCC through immunotherapy.
Expert opinion: GPC3 is an ideal cancer antigen for HCC immunotherapy. In resectable HCC, immunotherapies that leverage physiological immune surveillance, immune checkpoint inhibitors, and GPC3-target cancer vaccines appear promising in preventing recurrence and could be considered as a prophylactic adjuvant therapy. However, in advanced HCC, clinical trials have not demonstrated sufficient anti-tumor efficacy, in contrast with preclinical studies. Reverse translation, bedside-to-bench research, is crucial to identify the factors that have hindered GPC3 target immunotherapies.
