• Median overall survival, a secondary endpoint, reached nearly 3.5 years with Johnson & Johnson's RYBREVANT® plus LAZCLUZE® in atypical EGFR-mutated disease
  • Consistent responses observed across atypical EGFR mutation subgroups, including those historically associated with poorer outcomes
  • ASCO 2026 results reinforce the significance of RYBREVANT®-based regimens for patients across EGFR mutations

CHICAGO, May 29, 2026 /PRNewswire/ -- Johnson & Johnson (NYSE:JNJ) today announced updated results from the Phase 1/1b CHRYSALIS-2 study evaluating intravenous RYBREVANT® (amivantamab-vmjw) in combination with LAZCLUZE® (lazertinib) in patients with advanced non-small cell lung cancer (NSCLC) with atypical epidermal growth factor receptor (EGFR) mutations. The analysis showed encouraging long-term outcomes with RYBREVANT® plus LAZCLUZE® in this difficult-to-treat population. Median overall survival, a secondary endpoint, was nearly 3.5 years.1 The primary endpoint of objective response rate was previously reported.2 These results add to the growing body of evidence demonstrating the potential of RYBREVANT® plus LAZCLUZE® to deliver durable survival outcomes across both common and atypical EGFR-mutated advanced NSCLC in the first-line setting. Data were presented in an oral session at the 2026 American Society of Clinical Oncology (ASCO) Annual Meeting (Abstract #8501).
