Alterations in ERBB2, the gene encoding HER2, have been recognized as drivers in the development of NSCLC. Therefore, HER2 is an actionable biomarker that has emerged in NSCLC diagnosis and treatment. HER2 mutations activate the HER2 signaling pathway, which facilitates oncogenic transformation and increases tumor proliferation. Although practice guidelines recommend molecular testing to identify alterations, the interpretation of tests and application of testing results to treatment decisions remain areas of educational need. Despite HER2 testing and targeted therapies changing the treatment practices for other solid tumors, the previous standard of care for NSCLC has resulted in persistently low 5-year survival rates in contrast to the high rates of survival for breast cancer. However, successful targeting of HER2-activating mutations in advanced NSCLC has now been achieved through the use of antibody-drug conjugates (ADCs) such as trastuzumab deruxtecan (T-DXd). By effectively targeting HER2-activating mutations, ADCs have emerged as a promising treatment approach for advanced NSCLC.

In this educational activity, the expert faculty Chairperson will summarize relevant and timely information on NSCLC with HER2-mutant or overexpressing alterations and highlight the use of HER2-directed ADCs in NSCLC. The Chairperson will also provide their perspectives on the top key takeaways and why they are …
