Beamion LUNG-1 (ClinicalTrials.gov identifier: NCT04886804) is assessing the safety/efficacy of zongertinib (BI 1810631), a novel HER2-selective tyrosine kinase inhibitor that spares epidermal growth factor receptor, in patients with HER2-altered solid tumors. |\n| MATERIALS\u003Cbr>AND METHODS | Beamion LUNG-1 is an ongoing multicenter, multicohort phase Ia/Ib trial. Phase Ia assessed zongertinib administered twice a day (15-150 mg) or once daily (60-360 mg) in pretreated patients with various tumors, including NSCLC. Primary end points were maximum tolerated dose (MTD) and dose-limiting toxicities (DLTs); tumor response was a secondary end point. |\n| RESULTS | As of May 23, 2024, 105 patients were treated. Two DLTs occurred during the MTDevaluation period; MTD was not reached (NR). The recommended doses for expansion were 120 mg once daily and 240 mg once daily. Treatment-related adverse events (TRAEs; any/grade ≥3) occurred in 82%/10% of patients. The most common TRAEs (any/grade ≥3) included diarrhea (50%/1%), rash (16%/ 2%), anemia (10%/0%), decreased appetite (10%/1%), and increased alanine transaminase (10%/4%). The confirmed investigator-assessed overall response rate (ORR) across all doses/tumors was 30%(95% CI, 23 to 40); median duration of response was 12.7 months (95% CI, 6.9 to NR) . In 54 patients with NSCLC, confirmed ORR was 35%(95% CI, 24 to 49) . Activity was observed in patients with A775_G776insYVMA (ORR, 38%) and those who had received previous HER2-directed therapy (ORR, 28%) . In patients with NSCLC receiving zongertinib once daily, median progression-free survival was 17.2 months (95% CI, 8.3 to NR) . |\n| CONCLUSION | Zongertinib had a manageable safety profile and demonstrated preliminary antitumor activity in patients with HER2-altered tumors, including those with HER2-mutant NSCLC. |\n\nACCOMPANYING CONTENT  \n Data Sharing Statement  \n Data Supplement  Protocol  \nAccepted January 24, 2025 Published March 3, 2025  \nJ Clin Oncol 43:1337-1347 © 2025 by American Society of Clinical Oncology  \nView Online Article  \nCreative Commons Attribution Non-Commercial No Derivatives 4.0 License  \nINTRODUCTION  \nThe human epidermal growth factor receptor 2 (HER2), a member of the ErbB family of transmembrane receptors, plays a critical role in the regulation of cell proliferation and survival.1 HER2 alterations, including protein overexpression, gene amplification, and genetic mutations, occur frequently across many human malignancies including breast, gastric, and lung cancers.1 HER2-targeted agents have transformed care for patients with breast and gastric cancers. Nevertheless,  \nprimary and acquired resistance to therapy remains a challenge in these settings.2 To date, HER2-targeted agents have had less of an impact in non–small cell lung cancer (NSCLC) than in breast and gastric cancers. Only one HER2-targeted therapy, the antibody-drug conjugate trastuzumab deruxtecan, is approved for the treatment of NSCLC after previous systemic therapy in patients with HER2 mutations and, after a recent pan-tumor approval, patients with HER2-overexpressing tumors (immunohistochemistry of 31) .3 HER2-mutant NSCLC accounts for 2%-5% of all cases of  \n[ascopubs.org/journal/jco](ascopubs.org/journa","cbCaikUxzxsVsX7c","https://ap.wps.com/l/cbCaikUxzxsVsX7c","pdf",766494,"English","# Abstract\n## Purpose\n## Materials and Methods\n## Results\n## Conclusion\n# Introduction\n## Background on HER2 in cancer\n## Current HER2-targeted therapies in NSCLC\n# Context\n## Key Objective\n## Knowledge Generated\n## Relevance","[{\"question\":\"What is the main purpose of the Beamion LUNG-1 study?\",\"answer\":\"To assess the safety and efficacy of zongertinib (BI 1810631) in patients with HER2-altered solid tumors, including HER2-mutant NSCLC.\"},{\"question\":\"How was the phase Ia part of the trial designed?\",\"answer\":\"It is an ongoing multicenter, multicohort phase Ia/Ib trial where phase Ia evaluated zongertinib given twice daily (15–150 mg) or once daily (60–360 mg) in pretreated patients.
