Tislelizumab

(Redirected from BGB-A317)

Tislelizumab, sold under the brand name Tevimbra among others, is a humanized monoclonal antibody directed against PD-1.[6] 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.[7] It is being developed by BeiGene (after a period with Celgene Corp).[8]

Medical uses edit

China edit

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

  • in December 2019, to treat people with classical Hodgkin’s lymphoma (cHL) who have received at least two prior therapies,[9]
  • and in April 2020, to treat people with locally advanced or metastatic urothelial carcinoma (UC) with PD-L1 high expression whose disease progressed during or following platinum-containing chemotherapy or within 12 months of neoadjuvant or adjuvant treatment with platinum-containing chemotherapy.[10]

Adverse effects edit

Adverse effects include anemia, leukopenia, thrombocytopenia, nausea, increased aspartate transaminase (AST), neutropenia, fatigue, decreased appetite, vomiting, musculoskeletal pain, constipation, hypoproteinemia and rash.[11] Fatal events such as respiratory infection or failure, and hepatic injury have been reported.[12]

Adverse events are more common when combined with chemotherapy.[13]

Pharmacokinetics edit

Phase I clinical trial from 2016 has results suggesting an elimination half-life of 11 to 17 days.[6] A 2021 structural and functional analysis suggests a t1/2 of 238 ± 32 minutes, 30- to 80-times higher than pembrolizumab and nivolumab.[14]

History edit

Phase I trials began in the US and Australia in June 2015.[15] Some early results were announced in July 2016.[16][6]

A phase II clinical trial for urothelial cancer started in China in 2017.[7]

It has completed phase III trial for NSCLC.[17] As of April 2024, no results have been posted.

Tislelizumab "demonstrated efficacy and tolerability" in a multicenter phase III trial for advanced hepatocellular carcinoma started in January 2018.[8][18]
