For women: pregnant, or breastfeeding, or is considering becoming pregnant during the study. Currently taking interferon for other indications.

Design outcomes

Primary

MeasureTime frame
The primary endpoint will be the composite of: • hospitalization or emergency department visit within 30 days of randomization and/or • oxygen saturation <92% (as measured on study visit or at home by pulse oximetry by two consecutive readings) • death (by 30 days following randomization)

Secondary

MeasureTime frame
• hospitalization or emergency department visit within 30 days of randomization • oxygen saturation 30 [whichever is first] • time (in days as per the patient diary or study visit) to become asymptomatic • time (in days as per the patient diary or study visit) to have a =1 point improvement on the WHO ordinal COVID-19 symptom scale [see appendix 1 for scale]
