Baricitinib, Placebo and Antiviral Therapy for the Treatment of Patients With Moderate and Severe COVID-19

This phase II trial studies the effect of baricitinib in combination with antiviral therapy for the treatment of patients with moderate or severe coronavirus disease-2019 (COVID-19). Treatment with antiviral medications such as hydroxychloroquine, lopinavir/ritonavir, and/or remdesivir may act against infection caused by the virus responsible for COVID-19. Baricitinib may reduce lung inflammation. Giving baricitinib in combination with antiviral therapy may reduce the risk of the disease from getting worse and may help prevent the need for being placed on a ventilator should the disease worsen compared to antiviral therapy alone.
