Hepatocellular carcinoma is the most common type of primary liver cancer worldwide and is associated with a very poor prognosis.1 New cases and deaths due to HCC in China account for half of the global numbers and the 5-year survival rate for patients with HCC in China is only 14%.2
“While the incidence of HCC is increasing in China, the treatment landscape has not advanced accordingly; survival benefits with newer treatments are modest and multi-kinase inhibitors have sub-optimal tolerability,” said Lai Wang, Ph.D., Global Head of R&D at BeiGene. “We believe the evidence from our rigorously conducted global clinical development program for tislelizumab in HCC support the efficacy and favorable tolerability profile and look forward to working with NMPA on this submission and bringing a new treatment option to patients with HCC in China.”
The sBLA is supported by data from the RATIONALE 301 clinical trial (NCT03412773) that enrolled 674 patients from research centers across Asia, Europe, and the United States. RATIONALE 301 results were presented as a late-breaking oral presentation at the 2022 European Society for Medical Oncology (ESMO) Congress in Paris.
Tislelizumab was approved by the China NMPA as a treatment for nine indications, including conditional approval ‘for the treatment of patients with hepatocellular carcinoma (HCC) who have been previously treated with at least one systemic therapy’. Additional tislelizumab’s sBLAs under review at CDE include: combination with chemotherapy as a first-line treatment for patients with advanced or metastatic gastric or gastroesophageal junction adenocarcinoma whose tumors express PD-L1; combination with chemotherapy as first-line treatment in patients with unresectable locally advanced, recurrent or metastatic esophageal squamous cell carcinoma. Tislelizumab is not approved for use outside of China.
About Tislelizumab
Tislelizumab is a humanized IgG4 anti-PD-1 monoclonal antibody specifically designed to minimize binding to Fc-gamma (Fcγ) receptors on macrophages, helping to aid the body’s immune cells to detect and fight tumors. In pre-clinical studies, binding to Fcγ receptors on macrophages has been shown to compromise the anti-tumor activity of PD-1 antibodies through activation of antibody-dependent macrophage-mediated killing of T effector cells.
Tislelizumab is the first investigational medicine from BeiGene’s immuno-oncology biologics program and is being evaluated in solid tumor and hematologic malignancies, as monotherapy and in combination.
The global tislelizumab clinical development program includes more than 11,500 subjects enrolled to-date in 21 registration-enabling trials, from more than 30 countries and regions.
About RATIONALE 301
RATIONALE 301 (NCT03412773) is a global, Phase 3, randomized, open-label study of tislelizumab compared with sorafenib as a first-line treatment in adult patients with unresectable HCC. The primary endpoint of the study is non-inferiority of Overall Survival between the two treatment groups. The key secondary endpoint is Overall Response Rate, as assessed by Blinded Independent Review Committee (BIRC) per RECIST v1.1. Other secondary endpoints include other efficacy assessments such as Progression Free Survival, Duration of Response, and Time to Progression per BIRC, as well as measures of health-related quality of life, and safety and tolerability.
