The FLU- PRO Plus© questionnaire was specifically designed and validated to evaluate in clinical trials the presence, severity and duration of symptoms associated with viral infections. It contains 32 items (eg, felt hot, sweating, headache), grouped into 6 domains, that provide a comprehensive evaluation of such symptoms, using 5-point scales (values ranging from 0 to 4) with higher scores indicating worse symptoms. The number of days to resolution of the selected five COVID-19 symptoms (trouble breathing, chest congestion, dry or hacking cough, body aches and pains, and chills and shivering), defined as a reduction in the aggregate symptom score recorded on Day 0 (prior to study drug initiation) by the FLU-PRO Plus© questionnaire to or below 5 for a minimum of three consecutive days. Flu-PRO Plus© was created and supplied by Dr. John Powers and Leidos Biomedical, and the National Institute for Allergy and Infectious Diseases (NIAID).
