Timeframe: Days 14, 28, and 60 post randomization

Population: Subjects who reported a value from 0-2 on Days 14, 28, and 60.

Comparison of treatment group versus placebo group, respectively, in the average of daily scale value (0-8) on Days 14, 28, and 60 with respect to the number of subjects who reported as uninfected (scale value of 0), had no limitations (scale value of 1), or were experiencing limitations (scale value of 2). All patients had a score ranging between 0-2. A description of the WHO 9-Point Ordinal Scale follows: 0\. Uninfected or "no clinical or virological evidence of infection" * defined as subject answering "Yes" to "In the past 24 hours, have you returned to your usual health (before your COVID-19 illness)?" 1\. Not hospitalized, no limitations on activities * defined as subject answering "Yes" to "In the past 24 hours, have you returned to your usual activities (before your COVID-19 illness)?" 2. Not hospitalized, limitation on activities * defined as subject answering "No" to "In the past 24 hours, have you returned to your usual act
