Osimertinib più datopotamab deruxtecan nei pazienti con NSCLC avanzato con mutazione EGFR dopo progressione sull'osimertinib di prima linea: ORCHARD.

BACKGROUND: ORCHARD (NCT03944772) was a phase II platform study conducted to characterize resistance mechanisms and evaluate novel treatment combinations following progressive disease (PD) on first-line osimertinib. Datopotamab deruxtecan (Dato-DXd) is an anti-TROP2 antibody-drug conjugate approved as monotherapy in EGFR-mutated advanced non-small-cell lung cancer (NSCLC). We report final data from the osimertinib plus Dato-DXd module. METHODS: Eligible patients had EGFR-mutated advanced NSCLC and PD on first-line osimertinib. Patients received oral osimertinib (80 mg once daily) plus intravenous Dato-DXd (4 or 6 mg/kg every 3 weeks). The primary endpoint was investigator-assessed confirmed
