New Drug: SubQ Amivantamab with Lazertinib for EGFR-Mutated NSCLC

In the PALOMA-3 study, subcutaneous amivantamab-lazertinib showed noninferior efficacy to intravenous administration with improved safety and convenience. The subcutaneous route significantly reduced infusion-related reactions and demonstrated a superior overall survival. Subcutaneous administration also reduced venous thromboembolism rates.

  • Study

    Randomized, open-label, phase III trial [PALOMA-3]
    Patients with EGFR-mutated advanced NSCLC progressed after osimertinib and platinum-based chemotherapy
    Subcutaneous amivantamab+lazertinib (n=206) vs Intravenous amivantamab+lazertinib (n=212)



  • Efficacy

    ORR: 30% vs 33% (subQ vs. IV) (Non-inferior)
    mPFS: 6.1 mos vs 4.3 mos
    12-mo OS: 65% vs. 51% (HR 0.62 [0.42-0.92])



  • Safety

    Grade >=3 AE: dermatitis acneiform (9% vs 6%), lymphopenia (<1% vs 8%)
    Infusion-related reactions: 13% vs 66% (subQ vs. IV)
    Venous thromboembolism: 9% vs 14%
