NCT04433078

Brief Summary

The primary aim of this study is to test whether Doxycycline can benefit patients with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections by inhibiting the replication of the virus while at the same time blocking the development of cytokine storms or inhibiting cytokine-associated coagulopathy respectively. The investigators hypothesize that Doxycycline will will improve survival and reduce morbidity in SARS-CoV-2 infected patients. A secondary aim is to identify genetic variants that predict either an unusually mild disease or an unusually severe disease - knowledge that can be used to design new and precise medications and to be able to predict patients who might get into early trouble and to therefore hospitalize them.
