New Drug: Sacituzumab Tirumotecan for EGFR-Mutated Advanced NSCLC

Sacituzumab tirumotecan significantly improved progression-free survival and overall survival in patients with EGFR-mutated NSCLC resistant to previous EGFR-TKI therapy compared to standard chemotherapy. The treatment was associated with a lower incidence of serious adverse events.

  • Study

    Phase 3, open-label, multicenter, randomized trial [OptiTROP-Lung04]
    EGFR-mutated locally advanced or metastatic non-squamous NSCLC resistant to EGFR-TKI therapy
    Sacituzumab Tirumotecan (n=188) vs Pemetrexed plus platinum-based chemotherapy (n=188)



  • Efficacy

    ORR: 60.6% vs 43.1%
    mPFS: 8.3 mos vs 4.3 mos (HR 0.49 [0.39-0.62])
    18-month OS: 65.8% vs 48.0% (HR 0.60 [0.44-0.82])



  • Safety

    Grade >=3 AEs: decreased neutrophil count (39.9% vs 33.0%)
    Serious AEs: 9.0% vs 17.6%
    Treatment discontinuation rate due to AEs: 0% vs 0.5%
