A Study to Investigate the Efficacy and Safety of Dato-DXd with or without Osimertinib Compared with Platinum Based Doublet Chemotherapy in Participants with EGFR-Mutated Locally Advanced or Metastatic Non-Small Cell Lung Cancer - TROPION-Lung15

Exclusion Criteria

• - Use of chemotherapy, vascular endothelial growth factor inhibitor, immunotherapy or any anti-cancer therapy in the metastatic setting. Platinum-based chemotherapy in non-metastatic setting within 12 months prior to randomization.
• - History of another primary malignancy except for malignancy treated with curative intent with no known active disease within 2 years before the first dose of study intervention.
• - Any evidence of severe or uncontrolled systemic diseases, including, but not limited to active bleeding diseases, active infection, active ILD/pneumonitis, cardiac disease.
• - Has significant third-space fluid retention (example [eg.], ascites or pleural effusion) as judged by the investigator and is not amenable for required repeated drainage.
• - History of non-infectious ILD/pneumonitis including radiation pneumonitis that required steroids or drug-induced ILD, has current ILD/pneumonitis, or has suspected ILD/pneumonitis that cannot be ruled out by imaging at screening.
• - Has severe pulmonary function compromise resulting from intercurrent pulmonary illnesses.
• -Unstable spinal cord compression and/or unstable brain metastases.
• - Participants with symptomatic brain metastases (including leptomeningeal involvement).
• - Clinically significant corneal disease.
• - Uncontrolled infection requiring IV antibiotics, antivirals, or antifungals, suspected infections or inability to rule out infections.
• - Has known human immunodeficiency virus (HIV) infection that is not well controlled.
