Abstract Number: 4012: Advanced Unresectable/Metastatic Esophageal Squamous Cell Carcinoma: BeiGene

On 4th June 2021, BeiGene has presented Phase III efficacy results of the Anti-PD-1 Antibody Tislelizumab (BGB-A317) Versus Chemotherapy as Second-Line Treatment in Patients with Advanced Unresectable/Metastatic Esophageal Squamous Cell Carcinoma.

Among the enrolled patients, Of these 157 patients (tisle [n=89], ICC [n=68]) had vCPS ≥10% (PD-L1+ population). The study has met its primary endpoint: tisle clinically and significantly improved OS vs ICC in the ITT population (median OS: 8.6 vs 6.3 m). Tisle also demonstrated significant improvement in OS vs ICC in the PD-L1+ population (median OS: 10.3 vs 6.8 m). The survival benefit was consistently observed across pre-defined subgroups, including baseline PD-L1 status and region. Treatment with tisle was also associated with a higher ORR (20.3% vs 9.8%) and a more durable response (median DoR: 7.1 vs 4.0 m) than ICC in the ITT population. Fewer pts had ≥Grade 3 (46% vs 68%) treatment-emergent adverse events with Tislelizumab vs ICC. 

Expert ViewsTislelizumab demonstrated statistically significant and clinically meaningful improvement in OS vs ICC in pts with advanced or metastatic ESCC who had disease progression during or after first-line systemic therapy”. These results signify that Tislelizumab represents a potential new second-line treatment option for patients with advanced or metastatic Esophageal Squamous Cell Carcinoma.
