BeOne Medicines announced data from the HERIZON-GEA-01 trial, published in The New England Journal of Medicine and to be presented at the ASCO Annual Meeting on June 1 in Chicago, which evaluated Ziihera - zanidatamab - plus chemotherapy, with and without Tevimbra - tislelizumab -, compared with the control arm of trastuzumab plus chemotherapy as first-line treatment for advanced/metastatic HER2+ gastroesophageal adenocarcinoma, or GEA. The regimen of tislelizumab added to zanidatamab plus chemotherapy demonstrated meaningfully improved outcomes for patients with HER2-positive GEA. Findings show that this regimen resulted in a survival benefit, even in patients with PD-L1 less than1%. A statistically significant and clinically meaningful improvement in OS with Ziihera plus Tevimbra and chemotherapy reached a median OS of 26.4 months. Progression-free survival showed a statistically significant and clinically meaningful improvement in both Ziihera-containing arms with a median PFS of 12.4 months. Median duration of response was 20.7 months with Ziihera and Tevimbra plus chemotherapy. The safety findings for the Ziihera plus Tevimbra and chemotherapy arm were generally consistent with known effects and no new safety signals were identified. The FDA has accepted a supplemental Biologics License Applications for Tevimbra and has granted it priority review. China's National Medical Products Administration has accepted sBLAs for Ziihera and Tevimbra for the first-line treatment of advanced/metastatic HER2+ GEA. BeOne holds the rights to Ziihera in Asia, Australia, and New Zealand, and intends to work with authorities in these markets to expedite regulatory submissions.

TEVIMBRA and ZIIHERA Combination Therapy Significantly Improves Survival Rates
- Significant Survival Improvement: The HERIZON-GEA-01 trial demonstrated that the combination of TEVIMBRA and ZIIHERA with chemotherapy achieved a median overall survival of 26.4 months, compared to 19.2 months in the control group, indicating the potential importance of this combination in treating HER2+ gastroesophageal adenocarcinoma.
- Effective Regardless of PD-L1 Status: Results showed that this combination therapy provided significant survival benefits in both PD-L1 positive and negative patients, particularly in those with PD-L1 <1%, where the median survival was 29.7 months, far exceeding the control group's 15.8 months, highlighting its broad applicability.
- Strong Durability of Response: The median duration of response for the ZIIHERA and TEVIMBRA combination was 20.7 months, significantly longer than the 14.3 months for ZIIHERA alone and 8.3 months for the control group, underscoring the clinical significance of this combination in prolonging patient survival.
- Regulatory Progress: The U.S. FDA has accepted a supplemental Biologics License Application for TEVIMBRA with priority review, and the Chinese NMPA has also accepted applications for ZIIHERA and TEVIMBRA, indicating that this combination therapy is poised for rapid approval in multiple markets.
