The purpose of this study is to describe the clinical and health-related outcomes of amivantamab-containing regimens for the treatment of common epidermal growth factor receptor (EGFR) mutated non-small cell lung cancer (NSCLC; most common type of lung cancer) in a real-world setting. Metastatic NSCLC is when this disease spreads to other parts of body. NSCLC may occur due to mutations (changes) in many genes including epidermal growth factor receptor (EGFR).
