About TST001

TST001 is a humanized monoclonal antibody targeting human Claudin18 isoform 2 (CLDN18.2). CLDN18.2 is the tight junction protein with expression strictly confined to differentiated epithelial cells of the gastric mucosa. Published data indicates that CLDN18.2 is often overexpressed in gastroesophageal,pancreatic,lung,and other solid tumors,which makes it an attractive Antitumor therapeutic target. As a humanized monoclonal antibody with high binding affinity to CLDN18.2,TST001 kills tumor cells mainly by antibody-dependent cellular cytotoxicity (ADCC). In preclinical studies,TST001 is efficacious in multiple tumor animal models,and well tolerated in GLP toxicology studies.Transcenta has received IND clearance from FDA and NMPA for initiating clinical trials for TST001.
