Design outcomes

Primary

MeasureTime frameDescription
Proportion of patients with an aggravation of COVID-19within 8 days after treatmentThe aggravation is defined as a worsening of the score of at least 1 point on the WHO 7-point ordinal scale compared to the score on the WHO 7-point ordinal scale at randomization.

Secondary

MeasureTime frameDescription

Change in Clinical parameters : Supplemental O2Between randomization and Day 3, 5, 8 and 15L/min
Change in severity on Common Terminology Criteria of Adverse Events (CTCAE) scale (version 5.0)Between randomization and Day 3, 5, 8 and 15Shortness of breath and thoracic pain Scale score : Dyspnea: grade 1 (shortness of breath with moderate exertion) to 5 (death) Non-cardiac chest pain: grade 1 (mild pain) to 3 (severe pain)
Duration of patient's requirement in supplemental O2up to 15 daysTime requiring supplemental O2 at Day 15 will be defined as the time in days from randomization to the date of requiring supplemental O2.
Duration of aggravationup to 15 daysDuration of aggravation will be defined as the time in days between start date of aggravation and improvement date.
