Summary
This phase III trial compares best supportive care combined with low dose whole lung radiation therapy vs. best supportive care alone in treating patients with COVID-19 infection. Low-dose radiation therapy is a type of radiation treatment in which the total dose of radiation is less than that given in standard radiation therapy. The radiation dose used in this study is unlikely to cause short term side effects other than fatigue and temporary low blood cell count. The addition of low dose whole lung radiation therapy to best supportive care may improve patients' clinical status, the radiographic appearance of lungs and/or the laboratory blood tests.
