  • Research summary

    Current understanding of the COVID-19 pandemic show that a very significant fraction of infected patients develops pneumonia, systemic inflammatory response and cardiovascular complications with high morbidity and mortality. So far, there is a lack of consensus on the efficacy and safety of various treatment options targeting either the host (patients) or directly the virus. Our in vitro and in vivo evidence showed that, Leflunomide, a well established drug used to treat rheumatoid arthritis, has dual antiviral and anti-inflammatory properties. We propose a multicenter randomised clinical trial (3 UK NHS institutions, with a target total number of 178 to evaluate the efficacy and safety of Leflunomide compared with contemporary standard of care (as per emerging UK guidelines) in COVID-19 patients with moderate to critical clinical symptoms. The primary focus will be on clinical progression (complications and speed of recovery) and on kinetics of viral clearance. Additional objectives will centre on physiological and inflammatory events in relation to lung, heart and kidney dysfunction and severity of the systemic inflammatory reaction.
