Study Summary

This study includes a Dose Escalation Part to identify the recommended combination dose (RCD) and a Dose Expansion Part to further evaluate efficacy and safety. The primary objectives: Dose Escalation: To assess the safety and tolerability of HER3-DXd (patritumab deruxtecan; U3-1402) and osimertinib in subjects with locally advanced or metastatic non-small cell lung cancer (NSCLC) with an EGFR exon 19 deletion or L858R mutation with tumor progression after treatment with osimertinib, and to determine the recommended combination dose (RCD). Second-Line Dose Expansion Arm 1 and Arm 1b: To assess the preliminary antitumor activity of HER3-DXd and osimertinib in subjects with locally advanced or metastatic NSCLC with an EGFR exon 19 deletion or L858R mutation with tumor progression after treatment with osimertinib. Note: One or both of the study arms may open with one or two distinct dosing schedules. Second-Line Dose Expansion Arm 2: To assess the preliminary antitumor activity of HER3-DXd monotherapy in subjects with locally advanced or metastatic NSCLC with an EGFR exon 19 deletion or L858R mutation with tumor progression after treatment with osimertinib. First-Line Dose Expansion Cohorts 3, 4a, and 4b: To assess the preliminary antitumor activity of HER3-DXd and osimertinib in subjects with locally advanced or metastatic NSCLC with an EGFR exon 19 deletion or L858R mutation without prior systemic treatment for locally advanced or metastatic disease.

Primary Outcome

A DLT is defined as any TEAE not attributable to disease or disease-related processes that occurs during the DLT evaluation period and is ≥Grade 3, as defined in the protocol. A TEAE is defined as an adverse event (AE) with a start or worsening date during the on-treatment period. A serious AE is defined as any untoward medical occurrence that at any dose results in death, is life-threatening, requires inpatient hospitalization or prolongation of existing hospitalization, results in persistent o
