Descriptive Information
Brief Title  ICMJE An Adaptive Clinical Trial of Antivirals for COVID-19 Infection
Official Title  ICMJE An Adaptive Randomised Placebo Controlled Phase II Trial of Antivirals for COVID-19 Infection
Brief Summary This is a randomised placebo controlled phase II trial to examine the efficacy of antivirals to treat COVID-19 infection compared to placebo for virological cure and improved clinical outcomes. Individuals will be randomised to the candidate antiviral which in the first instance is Favipiravir or matched placebo and randomisation will be stratified according to whether the participant requires hospitalisation or not. This treatment will be given in addition to the usual standard of care in the participating hospital.
