The time to alleviation of targeted COVID-19 symptoms by Day 29 for participants with symptom alleviation, was calculated as symptom alleviation date/time minus first dose date/time. For participants who completed Day 29 of the study or discontinued from the study before Day 29 without symptom alleviation (censored) and without inter-current events, time was calculated as last date/time on which symptom alleviation was assessed minus the first dose date/time or Day 28, whichever occurred first. Symptom alleviation was defined as, all targeted symptoms scored moderate or severe at baseline were scored as mild/none and all targeted symptoms scored mild/none at baseline were scored as none, for at least 48 consecutive hours. Targeted symptoms included: stuffy or runny nose, sore throat, shortness of breath, cough, low energy or tiredness, muscle or body aches, headache, chills or shivering and feeling hot or feverish. Kaplan-Meier (KM) estimates were used in outcome measure analysis.

TEAEs were defined as 1 or both of the following: * Any AEs with an onset date on or after the study drug start date and no later than 30 days after permanent discontinuation of study drug. * Any AEs leading to premature discontinuation of study drug. Percentages were rounded off.

Treatment-emergent laboratory abnormalities were defined as values that increase at least 1 toxicity grade from baseline at any postbaseline time point, up to and including the date of last dose of study drug plus 30 days. Percentages were rounded off.
