Tislelizumab, sold under the brand name Tevimbra among others, is an anti-cancer medication used for the treatment of various forms of cancer. It is a humanized monoclonal antibody directed against programmed death receptor-1. [4] It is being developed by BeOne Medicines. [7]
Tislelizumab was approved for medical use in China in December 2019, [8] [9] in the European Union in September 2023, [5] in the United States in March 2024, [10] [11] and in Australia in May 2024. [1]
In China, tislelizumab is indicated to treat people with classical Hodgkin lymphoma who have received at least two prior therapies; [9] and to treat people with locally advanced or metastatic urothelial carcinoma with PD-L1 high expression whose disease progressed during or following platinum-containing chemotherapy or within twelve months of neoadjuvant or adjuvant treatment with platinum-containing chemotherapy. [12]
In the EU, tislelizumab is indicated for the treatment of adults with unresectable, locally advanced or metastatic esophageal squamous cell carcinoma after prior platinum-based chemotherapy. [5] In November 2024, the European Commission expanded the indication of tislelizumab for use alongside platinum- and fluoropyrimidine-based chemotherapy to treat people with HER2-negative locally advanced unresectable or metastatic gastric or gastroesophageal junction adenocarcinoma; and, in combination with platinum-based chemotherapy, for those with unresectable, locally advanced or metastatic esophageal squamous cell carcinoma. [5] [13]
In the US, tislelizumab is indicated for the treatment of adults with unresectable or metastatic esophageal squamous cell carcinoma after prior systemic chemotherapy that did not include a PD-(L)1 inhibitor; [4] and, in combination with platinum and fluoropyrimidine-based chemotherapy, it is indicated for the first-line treatment of adults with unresectable or metastatic HER2-negative gastric or gastroesophageal junction adenocarcinoma whose tumors express PD-L1. [4]
Adverse effects include anemia, leukopenia, thrombocytopenia, nausea, increased aspartate transaminase (AST), neutropenia, fatigue, decreased appetite, vomiting, musculoskeletal pain, constipation, hypoproteinemia and rash. [14] Fatal events such as respiratory infection or failure, and hepatic injury have been reported. [15]
Adverse events are more common when combined with chemotherapy. [16]
Phase I clinical trial from 2016 has results suggesting an elimination half-life of 11 to 17 days. [17] A 2021 structural and functional analysis suggests a t1/2 of 238 ± 32 minutes, 30- to 80-times higher than pembrolizumab and nivolumab. [18]
Phase I trials began in the United States and Australia in June 2015. [19] Some early results were announced in July 2016. [20] [17]
A phase II clinical trial for urothelial cancer started in China in 2017. [21]
Tislelizumab "demonstrated efficacy and tolerability" in a multicenter phase III trial for advanced hepatocellular carcinoma started in January 2018. [7] [22]
In November 2024, the European Medicines Agency expanded the indication of tislelizumab as part of a first-line combination treatment for adults with advanced gastric or esophageal cancer. [5]
Tislelizumab is the international nonproprietary name. [23]
