Trial Summary

Eligible participants will be those diagnosed with unresectable, locally advanced or metastatic histologically documented non-squamous NSCLC with HER2 exons 19 or 20 mutations and who are treatment-naïve for palliative intent systemic therapy for locally advanced or metastatic disease. The study aims to evaluate the efficacy, safety and tolerability of trastuzumab deruxtecan as first-line treatment of Non-Small Cell Lung Cancer (NSCLC) as compared with Standard of Care treatment (Investigator's choice of cisplatin or carboplatin + pembrolizumab + pemetrexed). This study aims to see if trastuzumab deruxtecan allows patients to live longer without the cancer getting worse or simply to live longer, compared to patients receiving standard of care treatment. This study is also looking to see how the treatment and the cancer affects patients' quality of life.

An Open-label, Randomized, Multicenter, Phase 3 Study to Assess the Efficacy and Safety of Trastuzumab Deruxtecan as First-line Treatment of Unresectable, Locally Advanced, or Metastatic NSCLC Harboring HER2 Exon 19 or 20 Mutations (DESTINY-Lung04)

Tumors with targetable alterations to EGFR (or other targetable mutations including but not limited to ALK, if routinely tested as a targetable alteration with approved available therapy)
Any untreated brain metastases, including asymptomatic or clinically inactive brain metastases
Active autoimmune or inflammatory disorders
Medical history of myocardial infarction within 6 months prior to randomization
History of non-infectious pneumonitis/ILD, current or suspected ILD
