Beamion LUNG-3: Adjuvant Zongertinib vs Standard Treatment in People With Completely Resected Stage II-IIIB NSCLC Harboring Activating HER2 TKD Mutations
Trial Status: active
Beamion LUNG-3 study evaluates whether zongertinib, an oral HER2-targeted treatment, can
improve outcomes compared with standard adjuvant treatment in adults with completely
resected Stage II-IIIB non-small cell lung cancer (NSCLC) whose tumors have activating
HER2 tyrosine kinase domain (TKD) mutations. Eligible participants must have undergone
curative-intent surgery and received guideline-appropriate perioperative systemic
therapy, either neoadjuvant platinum-based chemotherapy with or without immunotherapy, or
adjuvant platinum-based chemotherapy.
Participants are randomized 1:1 to receive zongertinib or standard of care, which may
consist of approved adjuvant immunotherapy or active surveillance, based on local
practice guidelines. The main purpose of the study is to determine whether zongertinib
can prolong disease-free survival compared to standard treatment. Safety and
patient-reported outcomes are also assessed.
Inclusion Criteria

Patients must be ≥18 years old or over the legal age of consent in their country
Male or female patients. Women of childbearing potential (WOCBP) must be ready and able to use dual highly effective methods of birth control per ICH M3 (R2) that result in a low failure rate of less than 1% per year when used consistently and correctly. A list of contraception methods meeting these criteria is provided in the patient information and in the study protocol
Histology and tumor sample: Histologically confirmed diagnosis of primary NSCLC
An archival tumor tissue sample must be submitted to the central laboratory after inclusion of the patient to retrospectively confirm the HER2 status
Staging: Pretherapeutic classification not exceeding Stage IIIB

Major surgery (major according to the investigator's assessment) performed within 4 weeks prior to randomization
Treatment with radiation therapy for primary NSCLC

Any investigational drug within 5 half-lives of the compound or any of its related material, if known
History or presence of
Active or known pre-existing or history of non-infectious interstitial lung disease/pneumonitis
Active infectious disease requiring systemic therapy
Uncontrolled gastrointestinal disorders affecting drug intake/absorption
Previous or concomitant malignancies within the last 3 years, except certain effectively treated cancers
Significant and/or uncontrolled cardiovascular abnormalities, QT interval corrected for heart rate by Fridericia formula (QTcF) >470 msec, or ejection fraction <50% Further exclusion criteria apply.
