Primary Outcome Measures
NameTimeMethod
Proportion of patients with an aggravation of COVID-19within 8 days after treatment

The 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 Outcome Measures
NameTimeMethod

Shortness 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 days

Time 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 days

Duration of aggravation will be defined as the time in days between start date of aggravation and improvement date.
