Summary
The global COVID-19 pandemic has caused unprecedented strain on health care services around the world.The absence of specific anti-viral medications to treat the underlying infection led to a proliferation of clinical studies and trials aimed at re-purposing existing medications. Human dihydroorotate dehydrogenase (DHODH) is vital enzyme utilised by viruses to replicate in the host cell. Leflunomide, a drug that is already licenced to treat rheumatoid arthritis, is a potent inhibitor of the enzyme DHODH. Importantly, this drug has dual anti-viral and anti-inflammatory properties so it targets viral replication and suppresses host inflammatory response which plays a role at more progressive stages of infection. DEFEAT-COVID is a multi-site, international, interventional, pragmatic, parallel group design, open label, randomised CTIMP with a pilot phase that will allow to adapt procedures and assessments if required. A phase III clinical trial of leflunomide for treating COVID-19 has been registered in China, Registration number: ChiCTR2000030058). The current proposal extends the original clinical study of leflunomide in China (People's Hospital of Wuhan University) to the UK through a structured collaboration.
