There is an urgent need for improved first-line therapy for advanced EGFR and ALK wild-type NSCLC, for which current molecularly targeted therapies are not indicated. Blockade of programmed cell death-1 (PD-1) and cytotoxic T-lymphocyte-associated antigen-4 (CTLA-4) immune checkpoints represents a promising anticancer therapeutic strategy. As PD-1 and CTLA-4 regulate immune responses by different mechanisms, targeting both pathways provides the potential for additive or synergistic effects. Durvalumab is a selective, high-affinity, engineered human IgG1 mAb that blocks programmed cell death ligand-1 (PD-L1) binding to PD-1 and CD80. Tremelimumab is a selective human IgG2 mAb against CTLA-4. In a Phase 1b study (NCT02000947), durvalumab + tremelimumab demonstrated a manageable tolerability profile in advanced NSCLC, with clinical activity observed both in pts with high levels of tumour PD-L1 expression and in pts with low/no tumour PD-L1 expression.

Trial design

NEPTUNE (NCT02542293) is a randomised, open-label, multicentre, global, Phase 3 study assessing durvalumab + tremelimumab vs standard of care in immunotherapy- and chemotherapy-naïve pts with advanced/metastatic EGFR and ALK wild-type NSCLC. Pts with either PD-L1 high expression or PD-L1 low/no expression (≥25% or
