Tislelizumab: First Approval.

Tislelizumab (®;; Tileilizhu Dankang Zhusheye) is an anti-human programmed death receptor-1 (PD-1) monoclonal IgG4 antibody that is being developed by BeiGene as an immunotherapeutic, anti-neoplastic drug. Tislelizumab has been investigated in haematological cancers and advanced solid tumours, leading to its approval in December 2019 in China for patients with relapsed or refractory classical Hodgkin's lymphoma after at least second-line chemotherapy. This article summarises the major milestones in the development of tislelizumab for this first approval for classical Hodgkin's lymphoma, and its potential upcoming approvals in other indications.
