Aerosolized Sargramostim Added to Immunotherapy for the Treatment of Patients With Metastatic Melanoma to the Lung

This phase II trial tests the safety, best dose, and effectiveness of inhaled aerosolized sargramostim in combination with standard immunotherapy (nivolumab) for the treatment of patients with melanoma that has spread from where it first started (primary site) to the lung (metastatic to the lung). Sargramostim works to stimulate the immune system by prompting the bone marrow to produce more white blood cells. Immunotherapy with monoclonal antibodies, such as nivolumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. In this study, an aerosolized form of sargramostim is inhaled using a device called a nebulizer, which can deliver the drug directly to the lungs. Inhalation of aerosolized sargramostim in combination with nivolumab may be more effective at treating patients melanoma metastatic to the lung.
