New indication based on results from a global Phase 3 trial demonstrating TEVIMBRA plus chemotherapy significantly improved overall survival for patients with advanced gastric cancers

Second FDA approval for TEVIMBRA in 2024

SAN MATEO, Calif., December 27, 2024--(BUSINESS WIRE)--BeiGene, Ltd. (NASDAQ: BGNE; HKEX: 06160; SSE: 688235), a global oncology company that intends to change its name to BeOne Medicines Ltd., today announced the U.S. Food and Drug Administration (FDA) has approved TEVIMBRA® (tislelizumab-jsgr), in combination with platinum and fluoropyrimidine-based chemotherapy, for the first-line treatment of unresectable or metastatic HER2-negative gastric or gastroesophageal junction adenocarcinoma (G/GEJ) in adults whose tumors express PD-L1 (≥1).

"Today’s FDA approval of TEVIMBRA for the treatment of gastric or gastroesophageal junction cancers in PD-L1 positive adult patients marks a significant step forward in our mission to deliver transformative therapies to patients with cancer," said Mark Lanasa, M.D., Ph.D., Chief Medical Officer, Solid Tumors at BeiGene. "This is the second U.S. approval for TEVIMBRA this year, underscoring its potential to address critical needs in oncology. We remain deeply grateful to the patients, clinicians, and researchers whose commitment and courage have made this progress possible—and we look forward to building on this momentum in 2025."

The additional indication for first-line G/GEJ cancers is based on results from BeiGene’s RATIONALE-305 (NCT03777657), a randomized, double-blind, placebo-controlled, global Phase 3 trial to evaluate the efficacy and safety of TEVIMBRA in combination with chemotherapy as a first-line treatment for adult patients with advanced unresectable or metastatic G/GEJ cancer. The study met its primary endpoint and demonstrated a statistically significant and clinically meaningful overall survival (OS) benefit with a median OS of 15.0 months for patients treated with TEVIMBRA in combination with the investigator’s choice of chemotherapy compared to 12.9 months for patients treated with placebo plus chemotherapy (n=997; HR: 0.80 [95% CI: 0.70, 0.92]; P=0.0011), resulting in a 20% reduction in the risk of death.

The pooled safety data in the application included 1,972 patients who received TEVIMBRA monotherapy in two randomized open-label, active-controlled studies (RATIONALE-302, BGB-A317-303) and five open-label, single-arm studies (BGB-A317-208, BGB-A317-204, BGB-A317-203, BGB-A317-102, BGB A317_Study_001), which enrolled 307 patients with esophageal squamous cell carcinoma and 1,665 patients with advanced or recurrent tumors. The most common Grade 3 or 4 adverse reactions for TEVIMBRA given in combination with chemotherapy were neutropenia, thrombocytopenia, anemia, fatigue, hypokalemia, hyponatremia, pneumonia, decreased appetite, rash, lymphopenia, alanine aminotransferase increased, aspartate aminotransferase increased, diarrhea, pneumonitis, and hepatitis.
