MARIPOSA Trial: EGFR-Mutant Lung Cancer Frontline Strategies
Panelists discuss the pivotal MARIPOSA trial, which examined combining amivantamab with lazertinib versus osimertinib monotherapy, showing improvements in progression-free survival (23.7 vs. 16.6 months), overall survival, CNS efficacy, and particularly strong benefits in high-risk subgroups such as TP53-mutant patients. Safety data from the trial highlighted the importance of prophylactic measures, especially for rash and other adverse events, noting that with current prophylaxis protocols, serious toxicity rates have been significantly reduced compared to the original study.
