Phase III, Open-label Study of First-line Osimertinib With or Without Datopotamab Deruxtecan for EGFRm Locally Advanced or Metastatic Non-small Cell Lung Cancer (TROPION-Lung14)

May 4, 2026 updated by: AstraZeneca

A Phase III, Open-label, Randomised Study of Osimertinib With or Without Datopotamab Deruxtecan (Dato-DXd), as First-line Treatment in Participants With Epidermal Growth Factor Receptor (EGFR) Mutation-positive, Locally Advanced or Metastatic Non-small Cell Lung Cancer

The purpose of this study is to evaluate efficacy and safety of osimertinib (tablet) in combination with Dato-DXd (i.v. infusion) compared with osimertinib (tablet) monotherapyas a first-line therapy in participants with locally advanced or metastatic EGFRm (Ex19del and/or L858R) NSCLC.

Study details include:

  1. The study duration will be event-driven, with an estimated duration of approximately 8 years.
  2. Participants may receive study treatment until disease progression, unacceptable toxicity, or other specific discontinuation criteria are met.
  3. The visit frequency will be every 3 weeks during the treatment period.

Note: Participants on osimertinib treatment(osimertinib only arm or who have discontinued Dato-DXd while are still receiving osimertinib) are required to attend visits to perform assessments every 6 weeks from Cycle 7 until Cycle 17 and then visits every 12 weeks until disease progression or IP discontinuation. Participants who are receiving osimertinib + Dato-DXd are still required to attend visit to perform assessment every 3 weeks (q3w) per SoA.

Exclusion Criteria:

  1. As judged by the investigator, any evidence of diseases (such as severe or uncontrolled systemic diseases, including active bleeding diseases, history of allogenic organ transplant which, in the investigator's opinion, makes it undesirable for the participant to participate in the study or that would jeopardise compliance with the protocol.

  5. Clinically significant corneal disease.
  6. Has active or uncontrolled hepatitis B or C virus infection, as defined by Protocol.
  7. Past medical history of ILD/penumonitis, including radiation pneumonitis (apart from radiation pneumonitis that did not require steroids), or drug-induced ILD/pneumonitis, or has suspected ILD/pneumonitis that cannot be ruled out by imaging at screening.
  8. Pulmonary embolism within 3 months of the study enrolment or has severe pulmonary function compromise.
  9. Has clinically severe pulmonary function compromise resulting from intercurrent pulmonary illnesses.
