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 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 patritumab deruxtecan 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 patritumab deruxtecan 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: To assess the safety and tolerability of patritumab deruxtecan 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.
