Johnson & Johnson Announces RYBREVANT and LAZCLUZE Study Results
Johnson & Johnson announced updated results from the Phase 1/1b CHRYSALIS-2 study evaluating intravenous RYBREVANT in combination with LAZCLUZE in patients with advanced non-small cell lung cancer with atypical epidermal growth factor receptor 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. The primary endpoint of objective response rate was previously reported. 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 Annual Meeting. "For patients with non-small cell lung cancer harboring atypical EGFR-mutations, first-line treatment decisions are often clouded by uncertainty regarding the efficacy of currently available EGFR tyrosine kinase inhibitors," said Joel Neal, M.D., Ph.D., principal investigator of the Phase 1/1b CHRYSALIS-2 study. "The responses we've seen in this trial suggest the potential for more durable disease control, and the overall survival data reinforce that picture. These long-term outcomes begin to change how we think about treatment options in managing this subtype of lung cancer." Neal is also a Professor of Medicine in the Division of Oncology at Stanford Medicine." "Disease progression and molecular resistance remain critical barriers in EGFR-mutated non-small cell lung cancer," said Yusri Elsayed, M.D., M.H.Sc., Ph.D., Global Therapeutic Area Head, Oncology, Johnson & Johnson. "RYBREVANT-based combinations demonstrate the power of changing the biology by addressing multiple disease drivers from the start rather than relying on single-pathway strategies. With strong outcomes across all known EGFR mutations, this approach is raising the bar for what first-line treatment can achieve."
