About Satri-cel

Satri-cel is an autologous CAR T-cell product candidate against the protein Claudin18.2 that can potentially be the first-in-class globally. Satri-cel has been developed for the treatment of Claudin18.2 positive solid tumors with a primary focus on gastric cancer/gastroesophageal junction cancer (GC/GEJ) and pancreatic cancer (PC). Ongoing trials include investigator-initiated trials (CT041-CG4006, NCT03874897), a confirmatory Phase II clinical trial for advanced GC/GEJ in China (CT041-ST-01, NCT04581473), a Phase I clinical trial for PC adjuvant therapy in China (CT041-ST-05, NCT05911217), and a Phase 1b/2 clinical trial for advanced gastric or pancreatic adenocarcinoma in North America (CT041-ST-02, NCT04404595). Satri-cel was granted Regenerative Medicine Advanced Therapy (RMAT) designation by the U.S. FDA for the treatment of advanced GC/GEJ with Claudin18.2-positive tumors in January 2022 and was granted PRIME eligibility by the EMA for the treatment of advanced gastric cancer in November 2021. Satri-cel received an Orphan Drug designation from the U.S. FDA in 2020 for the treatment of GC/GEJ and an Orphan Medicinal Product designation from the EMA in 2021 for the treatment of advanced gastric cancer.
