Design outcomes

Primary

MeasureTime frame
Comparison of change in SARS-CoV-2 viral load at 7 days from baseline through qRT-PCR test between patients receiving COVIFIGHT versus those receiving placebo.Timepoint: at 7 days from baseline through qRT-PCR test

Secondary

MeasureTime frame
1. Comparison of change in SARS-CoV-2 viral load. 2. Comparison of number of patients reaching Ct threshold (un-measurable viral load). 3. Number of patients requiring hospitalization for COVID-19/flu-like symptoms and/or requiring oxygen therapy or intubation or non-invasive ventilation or mechanical ventilation following enrollment. 4. Adverse events and Serious adverse events. â?? Number and type of adverse events and serious adverse events related to the study. 5. Patient reported outcome (PRO): â?? To assess common COVID-19 related symptoms using PRO questionnaire. 6. Time to clinical recovery: â?? Determining the time for clinical recovery by: Normalization of fever ( 99° F) Measurement of oxygen saturation at room air (SpO2 95%) Resolution of flu-like symptoms 7. Number of patients with negative conversion of SARS-CoV-2.Timepoint: 1. Time Frame: 24 hours, day 3, day 4 and day 7 from baseline 2. Time Frame: 24 hours, day 3, day 4, day 5 and day 7 from baseline 3. Time Frame: Through 15 days 4. Time Frame: Through 15 days 5. Time Frame: Baseline, 24 hours, day 3, day 4, day 5, day 7 and day 15 6. Time Frame: Through 15 days 7. Time Frame: day 3, day 4, day 5 and day 7
