U3-1402 in Metastatic or Unresectable Non-Small Cell Lung Cancer (NCT03260491)

A Multicenter, Open-Label Phase 1 Study of U3-1402 in Subjects With Metastatic or Unresectable Non-small Cell Lung Cancer

๐Ÿ”ต Active, Not Recruiting Phase1 ๐Ÿ’Š Investigational Drug / Biologic Sponsor: Daiichi Sankyo

๐Ÿฉบ Plain-English Summary (8th-Grade Level)

This study was designed to evaluate safety and antitumor activity of HER3-DXd in two parts: Dose Escalation and Dose Expansion. In Dose Escalation, HER3-DXd was evaluated in participants with metastatic or unresectable NSCLC with epidermal growth factor receptor (EGFR) activating mutation after disease progression during/after EGFR tyrosine kinase inhibitor (TKI) therapy. In Dose Expansion, HER3-DXd will be evaluated in participants with metastatic or unresectable NSCLC with EGFR activating mutation or squamous or non-squamous NSCLC (ie, without EGFR-activating mutations) with disease progression during/after systemic treatment for locally advanced or metastatic disease. In addition, HER3-DXd will be evaluated in participants with locally advanced or metastatic NSCLC whose tumors harbor a KRAS-G12C mutation after progression on the most recent line of therapy (Cohort 5).
