Amivantamab Plus Lazertinib vs Osimertinib in First-Line EGFR-Mutant Advanced NSCLC: Longer Follow-Up of the MARIPOSA Study

Panelists discuss insights from the MARIPOSA study on first-line treatment options for EGFR-mutant metastatic non–small cell lung cancer (NSCLC), highlighting the efficacy of amivantamab-lazertinib over osimertinib, the importance of managing adverse events, adherence to National Comprehensive Cancer Network guidelines, and the need for patient engagement in treatment discussions to address unmet needs.

Panelists discuss how the MARIPOSA study shows more patients in the amivantamab-lazertinib arm continued treatment compared to osimertinib, and many who progressed initiated subsequent therapy, primarily with carboplatin-pemetrexed.

Panelists discuss how they implement prophylactic strategies for treatment-related adverse events in the MARIPOSA study and how they counsel patients about managing these effects.

Panelists discuss the National Comprehensive Cancer Network (NCCN) guidelines for first-line treatment of EGFR-mutant metastatic non–small cell lung cancer (NSCLC), emphasizing the recommended therapies and best practices for patient management.

Panelists discuss key takeaways from the analysis of long-term results, noting that these findings may influence their recommendations for first-line regimens in EGFR-mutant metastatic non–-small cell lung cancer. They highlight how they engage patients in discussions about treatment options, considering efficacy and safety, while addressing remaining unmet needs in this therapeutic area.

Joshua K. Sabari, MD, and Sandip P. Patel, MD, discussed long-term findings from the phase 3 MARIPOSA trial.
