Precision Antibody Therapy in Gastric and Gastroesophageal Cancer: Targeting FGFR2b, CLDN18.2, and VEGFR2. (PubMed, Cells)
This review examines the mechanisms, safety profiles, and clinical trial outcomes of three targeted agents-bemarituzumab, zolbetuximab, and ramucirumab-which inhibit tumor growth through the FGFR2b, CLDN18.2, and VEGFR2 pathways, respectively. We also compare traditional versus adaptive clinical trial designs, explore emerging challenges such as therapeutic resistance and treatment-related toxicities, and consider implications for personalized medicine. Collectively, these agents represent a paradigm shift from empiric chemotherapy toward biomarker-driven immunotherapy, with the potential to significantly improve survival and quality of life in patients with advanced G/GEJ cancers.
