A Phase III, Open-label, Sponsor-blind, Randomized Study of Dato-DXd With or Without Osimertinib Versus Platinum-based Doublet Chemotherapy for Participants With EGFR-mutated Locally Advanced or Metastatic Non-small Cell Lung Cancer Whose Disease Has Progressed on Prior Osimertinib Treatment (TROPION-Lung15)
A Phase III, Open-label, Sponsor-blind, Randomized Study of Dato-DXd With or Without Osimertinib Versus Platinum-based Doublet Chemotherapy for Participants With EGFR-mutated Locally Advanced or Metastatic Non-small Cell Lung Cancer Whose Disease Has Progressed on Prior Osimertinib Treatment (TROPION-Lung15)
This study will assess the effect of Dato-DXd in combination with osimertinib or Dato-DXd monotherapy versus platinum-based doublet chemotherapy in terms of progression-free survival (PFS).
This is a Phase III, open-label, 3-arm, multicenter study assessing the effects of Dato-DXd in combination with osimertinib or Dato-DXd monotherapy versus platinum-based doublet chemotherapy in participants with epidermal growth factor receptor gene mutation (EGFRm) locally advanced or metastatic non-small cell lung cancer (NSCLC) whose disease has progressed on prior osimertinib treatment.
Participants will be randomized in a 1:1:1 ratio to one of the following intervention groups:
Participants will receive study intervention until Response Evaluation Criteria in Solid Tumors, Version 1.1 (RECIST v1.1) -defined radiological progression by the investigator, unacceptable toxicity, or other discontinuation criterion is met.
After study intervention discontinuation, all participants will undergo an end of treatment (EoT) visit within 35 days of discontinuation and will be followed up for safety assessments 28 (+ 7) days after their last dose of study intervention.
