Astra Zeneca (Immuno Stereotactic Ablative Body Radiotherapy) ISABR Study: Randomized Phase I/II Study of Stereotactic Body Radiotherapy

This study uses durvalumab (MEDI 4736), an experimental type of drug made by Astra Zeneca Pharmaceuticals, (limited partnership) LP, which in early studies has shown to possibly reduce the growth of certain types of lung cancer. The Investigators will enroll up to 105 subjects into the study. After an initial safety sample of 15 individuals receiving durvalumab (MEDI 4736) and Stereotactic Ablative Body Radiotherapy (SABR), if it is shown to be safe to administer this combination of therapies, the next enrolled subjects will be randomized in a 1:1 fashion (each subject with a "50-50 chance" like the flip of a coin) to receive either SABR and durvalumab (MEDI 4736), or SABR alone. Once treatment is completed, all subjects will return to the University of California at Los Angeles (UCLA) for regular follow-up visits to check on their health and outcomes. At visits both prior to and after treatment special blood samples will be drawn to be studied by UCLA scientists to look into the basic science aspects of how durvalumab (MEDI 4736) and radiation work in the body. It is hoped that we will learn more about the basic safety and science of durvalumab (MEDI 4736) combined with Stereotactic Ablative Body Radiotherapy (SABR) vs. SABR alone, while extending the life and quality of life of these subjects.
