      Background

      Approximately 20–25% of patients with NSCLC are diagnosed with early or localized disease, which has a relapse rate of 30–80% with surgery. Although neoadjuvant chemotherapy can reduce the risk of relapse, it only provides a pathological complete response (pCR; no viable tumor cells) rate of 4%. The neoadjuvant setting presents abundant tumor-associated neoantigens derived from the primary tumor that may allow immunotherapy to prime a long-lasting immune response. Clinical trial results support the use of immuno-oncology agents as neoadjuvant treatment for early-stage NSCLC. In a pilot study in patients with untreated, surgically resectable early-stage (stage I–IIIA) NSCLC, nivolumab (a fully human PD-1 immune checkpoint inhibitor antibody) administered as neoadjuvant treatment (3 mg/kg for 2 cycles during the 4 weeks prior to surgery) induced a pCR in 10% of patients and a major pathological response (MPR; ≤10% residual viable tumor cells in resected primary tumor) in 45% of patients, did not delay surgery, and was associated with an acceptable safety profile. Combining immuno-oncology agents with distinct mechanisms of action, such as PD-1 and CTLA-4 inhibitors, offers the possibility of a synergistic response and may improve antitumor activity compared with either agent alone. The combination of an immuno-oncology agent and chemotherapy may also offer synergistic activity, given that chemotherapy results in tumor cell death and subsequent antigen release that can activate an immune response. Promising results have been noted with nivolumab plus ipilimumab (a CTLA-4 immune checkpoint inhibitor antibody) and nivolumab plus chemotherapy in patients with treatment-naïve stage IIIB/IV NSCLC in the multicohort phase 1 CheckMate 012 study. CheckMate 816 (NCT02998528) is a phase 3 study evaluating nivolumab plus ipilimumab, nivolumab plus platinum-doublet chemotherapy, and platinum-doublet chemotherapy as neoadjuvant treatment for early-stage NSCLC.

      Approximately 642 patients aged ≥18 years with early-stage (stages IB–IIIA) resectable NSCLC, ECOG performance status 0–1, pulmonary function capable of tolerating lung resection, and available lung tumor tissue will be enrolled in North America, South America, Europe, Asia, and Africa. Patients are ineligible if they have active autoimmune disease or had received prior treatment with immune checkpoint inhibitors. Patients will be randomized (1:1:1) to receive neoadjuvant nivolumab plus ipilimumab, nivolumab plus platinum-doublet chemotherapy, or platinum-doublet chemotherapy. Primary endpoints are event-free survival and pCR. Key secondary endpoints are overall survival and MPR (<10% residual tumor in lung and lymph nodes). The start date was January 2017. The estimated primary completion date is May 2023.
