Additionally, bemarituzumab, ananti-FGFR2b monoclonal antibody, has shown improvements in combination withchemotherapy in those with HER2 negative GAC with FGFR2 overexpression...Lastly, TROP-2 has emergedas an exciting solid tumor target and study is expected in GAC. All three ofthese therapeutic targets have seen an abundance of drug development in recentyears, and we anticipate newer targeted agents driving therapeutic decisions inGAC in the coming years.

Review, Journal: New therapeutic target molecules for gastric and gastroesophageal junction cancer. (Pubmed Central) - Aug 26, 2024 Phase III and Ib/III trials of the FGFR2-targeted antibody bemarituzumab for G/GEJ cancer overexpressing FGFR2b are ongoing based on the promising result in a phase II trial, especially in cases with an FGFR2b positivity of???10%...CLDN18.2 is expressed in some G/GEJ tumors but lacks oncogenic driver potential, and the CLDN18.2-targeted antibody zolbetuximab prolonged the survival of CLDN18.2-positive G/GEJ cancer patients in phase III trials...Similarly, targeting of nondriver molecules such as DKK1, TROP2, and CEACAM5 is under investigation in early-stage clinical trials. This shift in focus from target molecules with driver potential to markers for precise drug delivery should increase the number of possible targets in G/GEJ cancer.

The next generation of small-molecule inhibitors, such as lirafugratinib and LOXO-435, and the FGFR2-specific antibody bemarituzumab are expected to have a reduced risk of hyperphosphataemia and the ability to overcome certain resistance mutations. In this Review, we describe the development and current clinical role of FGFR inhibitors and provide perspective on future research directions including expansion of the therapeutic indications for use of FGFR inhibitors, combination of these agents with immune-checkpoint inhibitors and the application of novel technologies, such as artificial intelligence.
