Early Intervention in COVID-19: Favipiravir Verses Standard Care
- Conditions
- Coronavirus Infection
- Interventions
- Other: Standard of care management
- Registration Number
- NCT04373733
- Lead Sponsor
- Chelsea and Westminster NHS Foundation Trust
- 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.
- 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.

Suspected or confirmed COVID-19 infection
Patients are suspected of COVID-19 infection if they have the following:
· Influenza like illness (fever ≥37.8°C and at least one of the following respiratory symptoms, which must be of acute onset: persistent cough, hoarseness, nasal discharge or congestion, shortness of breath, sore throat, wheezing or sneezing).

- Primary Outcome Measures
Name Time Method 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 Up to 28 days from randomisation 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
The seven-category ordinal scale is :
1. Not hospitalised with resumption of normal activities
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
Name Time Method Clinical status on a seven-category ordinal scale (Day 7) Day 7 from randomisation Clinical status of patients at given on the seven-category ordinal scale (see primary endpoint for scale)
