Evaluating a Fasting-mimicking Diet in Combination With Immunotherapy in Patients With Non-small Cell Lung Cancer

Cancer cells use an increased supply of glucose to make energy and do not have protection against fasting that normal cells do. Because of this, researchers would like to study how fasting may help immunotherapy target cancer cells. Initial studies suggest that fasting may decrease the side effects of immunotherapy and increase the chances of your cancer responding to the immunotherapy. Patient populations will have non-small cell lung cancer in which pembrolizumab have been recommended to treat the cancer as part of standard care
