Clinical Trial Summary

SARS-CoV-2 is causing an unprecedented stress on healthcare systems around the world, due to its high rate of infection and the high morbidity and mortality.

The COVID-19 infection triggers an inflammatory cascade with cytokine synthesis, prompting the immune response. Low dose radiotherapy (LD-RT) (≤ 100 cGy) induces an anti-inflammatory response, lowering levels of pro-inflammatory cytokines such as IL-1β or inhibit leukocyte recruitment. LD-RT has been used historically for the pneumonia treatment reporting a rapid clinical improvement (within the first week), as well as a reduced mortality (from around 30% to 10%). Considering these results, LD-RT can potentially afford a therapeutic benefit against SARS-CoV-2. The study purpose is to evaluate prospectively the safety and efficacy of LD-RT for SARS-CoV-2.
