The primary endpoints of this pilot trial will be the safety and feasibility of administering ipilimumab with Adoptive Cell Therapy (ACT) using TIL. The data analysis will mainly be descriptive. All study results will be preliminary and of exploratory in nature due to the pilot status and small sample size of the trial. Feasibility is defined as the ability to deliver at least 50% (i.e., two out of four) of the planned doses of ipilimumab and successfully treat at least 60% (i.e., ≥ 6/10) of the patients with TIL. All participants will be evaluable for toxicity from the time of their first protocol treatment. Toxicity will be reported by type and severity according to the National Cancer Institute Common Toxicity Criteria (NCI CTC) version 4.
