Tislelizumab^[1]^[2] (BGB-A317) is a humanized monoclonal antibody directed against PD-1.^[3] It prevents PD-1 from binding to the ligands PD-L1 and PD-L2 (hence it is a checkpoint inhibitor). It is being investigated as a treatment for advanced solid tumors.^[3]

It is designed to bind less to Fc gamma receptors.^[4]

It is being developed by BeiGene and Celgene Corp.^[5]

Clinical trials

Phase I trials began in the US and Australia in June 2015 and were expected to complete in mid-2017.^[6] Some early results were announced in July 2016.^[7]^[3]

A pivotal phase 2 clinical trial for urothelial cancer started in China in 2017.^[4]

It is in a phase 3 trial for NSCLC.^[8]

A multicenter phase 3 trial for advanced hepatocellular carcinoma started in Jan 2018.^[5]

Pharmacokinetics

Early phase I clinical trial results give an elimination half-life of 11 to 17 days.^[3]
