      Background:
      Current first-line therapy for advanced EGFR and ALK wild-type NSCLC is associated with poor survival and there remains a significant need for more effective treatments in this population. Blockade of immune checkpoints programmed cell death-1 (PD-1) and cytotoxic T-lymphocyte-associated antigen-4 (CTLA-4) represents a promising anticancer therapeutic strategy. In preclinical models, targeting both PD-1 and CTLA-4 provides for non-redundant pathway blockade and potential synergy. Durvalumab (MEDI4736) is a selective, high-affinity, engineered human IgG1 mAb that blocks programmed cell death ligand-1 (PD-L1) binding to PD-1 (IC~50~ 0.1 nM) and CD80 (IC~50~ 0.04 nM). Tremelimumab is a selective human IgG2 mAb inhibitor of CTLA-4. A Phase 1b study of durvalumab + tremelimumab demonstrated encouraging clinical activity and a manageable tolerability profile in advanced NSCLC, with activity observed in patients with high and low/no tumour PD-L1 expression (NCT02000947).

      Methods:
      NEPTUNE (NCT02542293) is a randomised, open-label, multicentre, global, Phase 3 study. Immunotherapy- and chemotherapy-naïve patients with advanced/metastatic EGFR and ALK wild-type NSCLC (with either PD-L1 high expression [≥25% tumour cells staining for PD-L1 at any intensity] or PD-L1 low/negative expression [<25% tumour cells staining for PD-L1 at any intensity] ) will be randomised (1:1) to durvalumab (20 mg/kg i.v. every 4 weeks [q4w] for up to 12 months) + tremelimumab (1 mg/kg i.v. q4w for up to 4 doses); or standard-of-care platinum-based doublet chemotherapy. The primary endpoint is overall survival (OS). Secondary endpoints are progression-free survival (PFS), objective response rate (ORR), duration of response and proportion of patients alive and progression free at 12 months by investigator assessment (RECIST v1.1); time from randomisation to second progression; OS, PFS and ORR in patients with PD-L1 low/negative NSCLC; safety (CTCAE v4.03) and tolerability; pharmacokinetics; and immunogenicity. Exploratory outcomes include potential biomarkers of response to treatment and impact of subsequent anticancer therapies on OS. Recruitment is ongoing. Figure 1
