Beamion LUNG-3: Adjuvant Zongertinib vs Standard Treatment in People With Completely Resected Stage II-IIIB NSCLC Harboring Activating HER2 TKD Mutations

Sponsored by Boehringer Ingelheim

About this study

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.

This is a global, randomized, open-label, Phase 3 study designed to assess the efficacy and safety of zongertinib as adjuvant therapy in participants with completely resected Stage II-IIIB NSCLC and HER2 TKD-activating mutations. Participants must have undergone complete resection and received perioperative systemic therapy consistent with current standards, including either neoadjuvant platinum-based chemotherapy with or without immunotherapy, or adjuvant platinum-based chemotherapy. After completing surgery and required systemic treatment, eligible participants are randomized 1:1 to receive either Zongertinib taken orally once daily for up to 3 years, or standard treatment, which may include an approved adjuvant immunotherapy agent administered according to its label, or observation, d…
