The proposed study will evaluate the safety and feasibility of preoperative administration nivolumab +/- ipilimumab in patients with high-risk resectable NSCLC, and will facilitate a comprehensive exploratory characterization of the tumor immune milieu and circulating immune cells and soluble factors in these patients. Data obtained in this study will provide valuable information for planning further prospective clinical trials of anti-PD-1 and other immunotherapies in NSCLC, both in the peri-operative and advanced disease setting. Ultimately, it is highly desirable to discover prospective biomarkers of response and toxicity to allow patients with NSCLC who are most likely to derive benefit to receive anti-PD-1 treatment, and conversely to minimize the risk of toxicity and ineffective treatment for patients who are unlikely to benefit.~In addition, an amendment to this study allows evaluation of the combination of nivolumab and the anti-CTLA4 antibody, ipilimumab in the neoadjuvant setting for the treatment of resectable NSCLC. In a large, multicohort, phase 1 trial, the ORR to combination ipilimumab and nivolumab therapy in patients unselected by PD-L1 status ranged from 39-47%. Incidence of grade 3-4 toxicity ranged from 33-37% across the combination ipilimumab and nivolumab cohorts which compares favorably with the rates of toxicity due to platinum doublet chemotherapy in this disease setting.~The current amendment includes addition of a third arm (Arm C) combining nivolumab and platinum-doublet chemotherapy in the neoadjuvant setting.
