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

Non-Small Cell Lung CancerPhase 3Stage IIIStage IVEGFR

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).

Conditions: Metastatic Non-small Cell Lung Cancer

Eligibility Criteria

Inclusion Criteria

  • Histologically or cytologically confirmed non-squamous NSCLC.
  • Must have evidence of documented pre-existing EGFRm information (EGFRm known to be associated with (epidermal growth factor receptor \[EGFR\] tyrosine kinase inhibitor \[TKis\] sensitivity \[Ex19del, L858R, G719X, S768I, or L861Q\], either alone or in combination with other EGFR mutations, which may include T790M).
  • Documented extra-cranial radiologic progression on prior osimertinib monotherapy (as most recent line of treatment) in the adjuvant, locally advanced, or metastatic setting.
  • Less than or equal to (\<=2) prior lines of EGFR TKIs (osimertinib is the only permitted prior third generation EGFR TKI).
  • At least one lesion, not previously irradiated, that qualifies as a RECIST v1.1 TL at baseline and can be accurately measured at baseline.
  • World Health Organization (WHO)/Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1.
  • Adequate bone marrow reserve and organ function within 7 days before randomization.

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 systemic antibiotics, antivirals, or antifungals, suspected infections or inability to rule out infections. Use of systemic antibiotics within 14 days of randomization.
  • Has known human immunodeficiency virus (HIV) infection that is not well controlled.
