Seoul – September 16, 2026 -- Johnson & Johnson reported that its RYBREVANT (amivantamab-vmjw) plus chemotherapy combination extended median overall survival to 34.3 months in patients with EGFR exon 20 insertion-mutated advanced non-small cell lung cancer, compared with 27.9 months for chemotherapy alone, according to final data from the Phase 3 PAPILLON study.
Combination therapy nearly doubles historical survival benchmarks
The result marks the longest reported median overall survival for this patient population, which has historically faced a five-year survival rate of just 8 percent and a median overall survival ranging from 16 to 24 months. EGFR exon 20 insertion mutations account for approximately 12 percent of all EGFR mutations and have proven difficult to treat with existing targeted therapies.
