Summary
This early phase I trial investigates whether low-dose interleukin-2 (IL-2) and pembrolizumab works in treating patients with stage IV non-small cell lung cancer. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. IL-2 works in the body to help create more T-cells and strengthens the immune system. Giving IL-2 and pembrolizumab may improve the response of the immune system against cancer and result in better outcomes in patients with stage IV non-small cell lung cancer.
