Abstract

Non-small cell lung cancer (NSCLC) that overexpresses human epidermal growth factor receptor 2 (HER2) is associated with poor prognosis, and no HER2-targeting therapies for HER2-overexpressing NSCLC are currently approved in the first-line setting. Pembrolizumab plus pemetrexed and platinum-based chemotherapy is a recommended first-line treatment option for nonsquamous NSCLC with no actionable genomic alterations. However, improved outcomes with pembrolizumab-based therapies correlate with higher programmed death-ligand 1 (PD-L1) levels, underscoring the need for more targeted treatment options for patients with lower PD-L1 tumor proportion scores (TPS; <50%). DESTINY-Lung06 is a multicenter, open-label, randomized, phase III trial evaluating the efficacy and safety of trastuzumab deruxtecan (T-DXd) in combination with pembrolizumab in the first-line setting in patients with HER2-overexpressing (≥25% moderate/strong membrane staining), PD-L1 TPS <50% NSCLC. Planned enrollment will be approximately 686 patients randomly assigned to either T-DXd 5.4 mg/kg with pembrolizumab 200 mg intravenously every 3 weeks (Q3W) or pembrolizumab 200 mg plus pemetrexed 500 mg/m² with platinum-based chemotherapy (cisplatin 75 mg/m² or carboplatin under the concentration-time curve 5 mg min/mL) intravenously Q3W. Progression-free survival by blinded independent central review and overall survival are the primary and key secondary endpoints of the study, respectively.Clinical trial registration: www.ClinicalTrials.gov identifier is NCT06899126; EudraCT identifier is 2024-515658-26-00.
