Antibody
Comment: Zolbetuximab (IMAB362) is an investigational, first-in-class monoclonal antibody targeting the cell surface molecule claudin18.2 (CLDN18.2), a pan-cancer drug target [5,9]. Claudin-18 is a tight-junction protein. Splice variant 2 is reported to be a highly selective cell lineage marker of gastric mucosal cells, and it is an active molecular target for tumour-targeted immunotherapy [1-2,4]. CLDN18.2 is retained on malignant transformation and is expressed in a significant proportion of primary gastric cancers and their metastases, and ectopic expression of CLDN18.2 is identified in distinct histologic subtypes of pancreatic (primary tumour and metastases) [10], esophageal, ovarian, and lung tumours [5]. Zolbetuximab binds to the first extracellular N-terminal domain which is unique to the CLDN18.2 splice variant [5,10].
