Brief Summary:
Currently we do not know how best to treat patients infected with COVID-19. This study is looking at whether randomising participants to either favipiravir or to usual care, can help patients with suspected or proven COVID-19 infection.

Condition or disease Intervention/treatment Phase
Coronavirus Infection Drug: Favipiravir Other: Standard of care management Phase 3

Detailed Description:

A prospective, randomised, open label study of the combined use of favipiravir and standard clinical care verses standard clinical care alone.

A computer-based software will randomise participants 1:1 to either receive favipiravir and standard medical care or standard medical care alone. The allocated medical regime will commence for 10 days.

Research blood, sputum nose swab and urine samples will be collected at baseline, as well as between day 5 and 10, and between day 14 and 28 to enable comparative analyses.

A COVID-19 antibody test will also be performed 14-28 days after randomisation. In the event of clinically indicated bronchoscopy taking place within 28 days of consent then additional bronchoscopy washing and brushing samples and paired blood sample will be taken for research purposes If a participant is discharged before one of the latter time points, they will be required to return to hospital (provided they are well enough) for the collection of repeat samples.

Participants will be closely monitored whilst taking the study medications. Participants will study exit at subject death or 28 days post-randomisation.

Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Time from randomisation to a sustained clinical improvement (maintained for 24 hours) by two points on a seven-category ordinal scale or to discharge, whichever occurs first [ Time Frame: Up to 28 days from randomisation ]

    2. Not hospitalised, but unable to resume normal
    3. Hospitalised, not requiring supplemental oxygen
    4. Hospitalised, requiring supplemental oxygen
    5. Hospitalised, requiring nasal high-flow oxygen therapy, non-invasive mechanical ventilation or both
    6. Hospitalised, requiring ECMO (Extra-corporal membrane oxygenation), invasive mechanical ventilation or both
    7. Death


Secondary Outcome Measures :
  1. Clinical status on a seven-category ordinal scale (Day 7) [ Time Frame: Day 7 from randomisation ]

    Survival of patients to end of study

  4. Time to improvement by two points on the NEWS score [ Time Frame: Up to 28 days from randomisation ]

  7. Time to improvement by two points on the NEWS element score for respiratory rate [ Time Frame: Up to 28 days from randomisation ]
    Time from randomisation to improvement by two points on the NEWS element score for respiratory rate, if maintained for 24 hours. For details of NEWS score see https://www.rcplondon.ac.uk/projects/outputs/national-early-warning-score-news-2

  8. Time to improvement by two points on the NEWS element score for oxygen saturation. [ Time Frame: Up to 28 days from randomisation ]
