Transcenta Holding Limited, a clinical stage biopharmaceutical company with fully-integrated capabilities in discovery, research, development and manufacturing of antibody-based therapeutics, announces that it has established a global clinical collaboration with Bristol Myers Squibb to evaluate the combination of TST001, an investigational humanized monoclonal antibody targeting Claudin18.2 developed by Transcenta, with Opdivo (nivolumab), Bristol Myers Squibb's anti-PD-1 therapy, for the treatment of patients with unresectable locally advanced or metastatic gastric cancer or gastroesophageal junction cancer (GC/GEJ).

This collaboration includes two global phase I/II open-label, multi-center studies, one to be held in the U.S. and one to be held in China, to evaluate the safety, tolerability, and anti-tumor efficacy of TST001 in combination with Opdivo in patients with unresectable locally advanced or metastatic Claudin18.2 expressing gastric / gastroesophageal junction cancer with or without previous treatment.

Under the terms of the agreement, Transcenta will be the sponsor of the trials and Bristol Myers Squibb will supply Opdivo to Transcenta for use in its combination therapy studies with TST001.
