Landmark Phase 3 MARIPOSA Study Meets Primary Endpoint Resulting in Statistically Significant and Clinically Meaningful Improvement in Progression-Free Survival for RYBREVANT® (amivantamab-vmjw) plus Lazertinib Versus Osimertinib in Patients with EGFR-Mutated Non-Small Cell Lung Cancer

*September 2023*

RARITAN, N.J., Sept. 28, 2023 /PRNewswire/ — The Janssen Pharmaceutical Companies of Johnson & Johnson today announced positive topline results from the Phase 3 MARIPOSA study evaluating RYBREVANT® (amivantamab-vmjw), a bispecific antibody targeting epidermal growth factor receptor (EGFR) and mesenchymal-epithelial transition (MET), in combination with lazertinib, an oral third-generation EGFR tyrosine kinase inhibitor (TKI), versus osimertinib as first-line treatment in patients with locally advanced or metastatic EGFR-mutated non-small cell lung cancer (NSCLC).1

The pivotal Phase 3 MARIPOSA study met its primary endpoint with a statistically significant and clinically meaningful improvement in progression-free survival (PFS) in patients receiving RYBREVANT® plus lazertinib compared to osimertinib. The combination of RYBREVANT® and lazertinib demonstrated a safety profile consistent with previously reported data on the combination. A planned interim overall survival (OS) analysis showed a trend favoring the combination of RYBREVANT® and lazertinib compared to osimertinib. Patients in the study will be followed for subsequent OS analyses, which will determine the statistical and clinical significance of OS.1*

“Positive topline results from the MARIPOSA study reinforce the potential of the RYBREVANT and lazertinib combination in frontline EGFR-mutated non-small cell lung cancer as a future standard of care,” said Peter Lebowitz, M.D., Ph.D., Global Therapeutic Area Head, Oncology, Janssen Research & Development, LLC. “As a combination targeted regimen, RYBREVANT and lazertinib inhibit critical oncogenic driver pathways and activate the immune system to address disease in multiple ways.” Read more.
