This indication is approved under accelerated approval based on objective response rate and duration of response. Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial.
“With the approval of zongertinib, we have an effective, targeted, orally administered treatment option for patients with HER2 (ERBB2)-mutant non-small cell lung cancer in the U.S. that not only elicits a durable response but, importantly, has a manageable safety profile,” said Dr. John Heymach, MD, PhD, chair of Thoracic/Head and Neck Medical Oncology at The University of Texas MD Anderson Cancer Center, and coordinating investigator for the Beamion-LUNG 1 trial. “In a patient population where there are currently limited treatment options, this approval represents a significant advancement in cancer care.”
Accelerated approval is based on data from the Phase Ib Beamion-LUNG 1 trial, demonstrating an objective response rate of 75% (N=71), 6% of patients had a complete response and 69% of patients had a partial response and a duration of response of ≥6 months in 58% of patients (n=53). Positive results from the Beamion-LUNG 1 trial were previously presented at the American Association for Cancer Research (AACR) Annual Meeting 2025 and simultaneously published in The New England Journal of Medicine.
Zongertinib demonstrated a manageable safety profile with a 2.9% discontinuation rate.
“We are grateful to be able to bring forward HERNEXEOS, which has the potential to reset the benchmark for those living with HER2-mutant advanced non-small cell lung cancer, a condition associated with a particularly poor prognosis,” said Shashank Deshpande, Chairman of the Board of Managing Directors and Head of Human Pharma at Boehringer Ingelheim. “Believing in the power of scientific innovation, we aim to provide meaningful improvements to this patient population. Recognizing its potential, we accelerated development to deliver this new treatment option to patients within four years of starting the first clinical trial."
HER2 (ERBB2) mutations occur in approximately 2–4% of NSCLC cases and are associated with a poor prognosis and higher incidence of brain metastases. Alterations in the HER2 (ERBB2) gene, including mutations, amplification and overexpression, trigger uncontrolled cell proliferation, inhibiting cell death, and promoting tumor growth and spread. Comprehensive biomarker testing using next generation sequencing determines a patient’s eligibility for treatment with zongertinib by identifying HER2 (ERBB2)-mutant advanced NSCLC.
“The advocacy community is thrilled about the approval of zongertinib, as it is another testament to the importance of personalized options for lung cancer that allow for a much more targeted approach for a subgroup of patients who have been waiting many years for innovative treatments,” said Marcia Horn, President and CEO, International Cancer Advocacy Network and Executive Director of the Exon 20 Group/HER2 Warriors. “Understanding your cancer’s unique biomarkers, including HER2, through comprehensive testing is critical for all patients with NSCLC, as it can unlock targeted treatment options.”
