FDA Approval Marks A Turning Point For BeOne Medicines (ONC)
BeOne Medicines (ONC) announced FDA approval for TEVIMBRA in combination with ZIIHERA and chemotherapy for HER2-positive gastroesophageal adenocarcinoma. The approval is based on Phase 3 trial data showing a median survival of 26.4 months. The company reported Q2 2026 revenue of $1.7 billion, up 30% YoY, and raised full-year revenue guidance to $6.6B-$6.8B. However, a Phase 3 study for zanubrutinib-sonrotoclax combination did not meet its primary endpoint.
