Intervention model description: We hypothesize that Durvalumab and stereotactic radiotherapy, in the form of PULSAR and SAbR, and durvalumab will confer a 60% increase in improvement in quality of life over the historical control rate of 33%, for an absolute improvement of 27%. Using a two-sided exact binomial test with a two-sided significance level of 0.1 and 80% power, we estimate that we will need to enroll 23 patients per arm do detect a difference. Accounting for 10% attrition, we will plan to enroll 52 patients.
Primary purpose: TREATMENT

Brief summary: This is a randomized Phase II study which is designed to determine the impact of stereotactic radiotherapy and durvalumab on quality-of-life and oncologic outcomes in patients with advanced non-small cell lung cancer. Durvalumab (Imfinzi) and stereotactic radiotherapy, with each fraction of radiotherapy is given every other day on a standard stereotactic ablative radiotherapy (SAbR) schedule or every four weeks on the personalized ultra-fractionated stereotactic adaptive radiotherapy (PULSAR) schedule. Subjects will be followed for a period of 2 years after completion of treatment or until death, whichever occurs first. Specifically, subjects will be followed at 1, 3, 6, 9, 12, 15, 18, 21, and 24 months following treatment. After the 2 year follow up, the patient can continue routine follow up with their physicians, per standard of care. Subjects removed from therapy for unacceptable adverse events will be followed until resolution or stabilization of the adverse event.
