Tislelizumab, sold under the brand name Tevimbra among others, is a humanized monoclonal antibody directed against PD-1.[5] It prevents PD-1 from binding to the ligands PD-L1 and PD-L2 (hence it is a checkpoint inhibitor). It is designed to bind less to Fc gamma receptors.[6] It is being developed by BeiGene (after a period with Celgene Corp).[7]

Medical uses

China

Tislelizumab was approved by China's National Medical Products Administration :

History

Phase I trials began in the US and Australia in June 2015.[10] Some early results were announced in July 2016.[11][5]

A phase II clinical trial for urothelial cancer started in China in 2017.[6]

It is in a phase III trial for NSCLC.[12]

A multicenter phase III trial for advanced hepatocellular carcinoma started in January 2018.[7]

Pharmacokinetics

Phase I clinical trial results give an elimination half-life of 11 to 17 days.[5]
