A Pilot Trial of Proton Based Cardiac Sparing Accelerated Fractionated RadioTherapy in Unresectable Non-Small Cell Lung Cancer with Extended Durvalumab Therapy (PARTICLE-D)

Concurrent chemoradiotherapy is the current non-surgical standard of care for locally advanced non-small cell lung cancer (NSCLC). However, this is a difficult regimen to tolerate especially for those who are elderly, have multiple comorbidities or poor performance status. Alternative treatment regimens are needed for this vulnerable population. We report initial results of concurrent durvalumab, an immune checkpoint inhibitor, and hypofractionated, dose-escalating, proton external beam radiotherapy (EBRT).
