Summary
Hydroxychloroquine is widely used to treat autoimmune diseases. Clinical investigation has found that a high concentration of cytokines were detected in the plasma of critically ill patients infected with SARS-CoV-2, therefore, hydroxychloroquine as anti-inflammatory agents may reduce this response in accord with their use in autoimmune disease where the cytokine response can be reduced. Favipiravir is an antiviral drug developed in Japan that the data sheet notes that it is a pyrazinecarboxamide derivative with activity against influenza viruses, west nile virus, yellow fever virus, foot and mouth disease virus as well as against flaviviruses, arenaviruses, bunyaviruses and alphaviruses. In February the drug was used for COVID-19 disease in China and was declared effective in treatment, and a report published (in press) comparing Favipiravir with Lopinavir /ritonavir suggested that Favipiravir was superior for prevention of disease progression and viral clearance. The objective of this pilot study is to compare three arms: hydroxychloroquine; favipiravir; standard care (no specific SARS-CoV-2 treatment) only, in symptomatic patients infected by SARS-CoV-2 in an open label randomized clinical trial. The difference between groups will allow an effect size to be determined for a definitive clinical trial.
