Transcenta, biologics, antibody
TST001 is the second most advanced Claudin18.2 targeting antibody therapeutic candidate being developed globally. It is generated by using Transcenta's Immune Tolerance Breaking Technology (IMTB) platform.
TST001 has high affinity, and enhanced antibody-dependent cellular cytotoxicity (ADCC) and complement-dependent cytotoxicity (CDC).
Since August 2020, clinical trials for TST001 are ongoing in China and US (NCT04396821, NCT04495296/CTR20201281). TST001 was granted Orphan Drug Designation in the US by FDA for the treatment of patients with gastric cancer or gastroesophageal junction (GC/GEJ).
Claudin18.2 is a transmembrane protein highly expressed in multiple solid tumor cells. In normal tissues, the expression of Claudin18.2 is restricted to the differentiated epithelial cells of the stomach. The high tissue specificity and tumor specificity makes Claudin18.2 an extremely promising target for next-generation targeted therapy.
TST001 kills Claudin18.2 expressing tumor cells by mechanisms of antibody-dependent cellular cytotoxicity (ADCC) and complement-dependent cytotoxicity (CDC). Leveraging advanced bioprocessing technology, the fucose content of TST001 was significantly reduced during the production, which further enhanced NK cells mediated ADCC activity of TST001.
♦ TST001 Has Promising Anti-tumor Activities and BIC/FIC Potentials
1）One Confirmed PR Achieved in Dose Escalation Studyin Late Line GC Patient at 6mg/kg
2）Confirmed PR in Pre-treated Pancreatic Cancer Patient with Medium-low CLDN18.2 Expression
Transcenta owns the global rights of TST001 and has filed multiple patent applications for therapeutic and diagnostic antibodies targeting Claudin18.2 .
