New Reference: Osimertinib with Platinum-Pemetrexed for Advanced EGFR-Mutated NSCLC

The FLAURA2 trial found that osimertinib plus chemotherapy resulted in significantly longer overall survival compared to osimertinib alone in patients with EGFR-mutated advanced NSCLC. The addition of chemotherapy increased the occurrence of adverse events, primarily myelosuppressive effects, but these were reversible with supportive care.

  • Study

    Randomized, open-label, phase 3 study [FLAURA2; NCT04035486]
    EGFR-mutated advanced NSCLC (exon 19 deletion or L858R mutation) who had not received prior treatment for advanced disease
    Osimertinib + platinum-pemetrexed (n=279) vs Osimertinib monotherapy (n=278)



  • Efficacy

    mOS: 47.5 mos vs 37.6 mos (HR 0.77 [0.61-0.96])



  • Safety

    Grade >=3 AE: 70% vs 34%
    Adverse events leading to discontinuation of osimertinib: 12% vs 7%
