Nivolumab in Patients With Advanced Non-Small Cell Lung Cancer and Pre-existing Autoimmune Disease

The purpose of this study is to explore the safety, tolerability and activity of Nivolumab, a PD-1 inhibitor, in cohorts of patients with autoimmune disease. Two cohorts of patients will be enrolled, based on autoimmune disease type as outlined below. Entry into cohorts 1 and 2 will start simultaneously and enroll independently. Cohort 1: Rheumatoid arthritis, psoriasis, giant cell arteritis/polymyalgia rheumatica, systemic lupus erythematosis Cohort 2: Other autoimmune diseases (ulcerative colitis, Crohn's disease, multiple sclerosis). Patients must be discussed with PI prior to enrollment. Patients will be screened within 28 days prior to the start of dosing. Eligible patients will be enrolled in either of the two cohorts. Patients will receive treatment every two weeks, in an outpatient setting. One cycle is a 28-day period, with Nivolumab given on days 1 and 15 of a 28-day cycle. Subjects will be permitted to continue treatment beyond initial RECIST 1.1. For each cohort, all patients will be dosed at 240 mg IV. There will be no dose de-escalation or escalation from this dose level. Participants will be followed with telephone follow up for two years after removal from protocol therapy or until death, whichever occurs first. Phone calls will be placed every six months and survival follow up obtained. Participants removed from protocol therapy for unacceptable adverse event(s) will be followed until resolution or stabilization of the adverse event, in addition to the follow up for two years after removal from protocol therapy or until death, whichever occurs first.
