General information about the trial
|
|||
Main objective of the trial |
The primary objectives of this study were to evaluate the efficacy of remdesivir (RDV) in reducing the rate of of coronavirus disease 2019 (COVID-19) related hospitalization or all-cause death in non-hospitalized participants with early stage COVID-19 and to evaluate the safety of RDV administered in an outpatient setting.
|
||
Protection of trial subjects |
The protocol and consent/assent forms were submitted by each investigator to a duly constituted Independent Ethics Committee (IEC) or Institutional Review Board (IRB) for review and approval before study initiation. All revisions to the consent/assent forms (if applicable) after initial IEC/IRB approval were submitted by the investigator to the IEC/IRB for review and approval before implementation in accordance with regulatory requirements.
This study was conducted in accordance with recognized international scientific and ethical standards, including but not limited to the International Conference on Harmonization guideline for Good Clinical Practice (ICH GCP) and the original principles embodied in the Declaration of Helsinki.

End point description |
The time-weighted average change from baseline to study Day 7 (DAVG7) in SARS-CoV-2 viral load is defined as the time-weighted average between the first postbaseline value through the last available value up to Day 7 minus the baseline value in SARS-CoV-2 viral load (log10 copies/mL). DAVG7 is calculated using the trapezoidal rule and the area under the curve (AUC). For participants with data through days prior to Day 7, the time-weighted average change used data up to last available timepoint. If there was no postbaseline data, the participant was excluded from the analysis. Participants in the Virology Analysis Set (all the participants who were randomized into the study, received at least 1 dose of study treatment, and had positive SARS-CoV-2 viral load at baseline) with available data were analyzed.

Time to Alleviation (Mild or Absent) of Baseline COVID-19 Symptoms as Reported on the COVID-19-adapted Influenza Patient-Reported Outcome Plus Questionnaire (FLU-PRO Plus) | ||||||||||||
End point description |
The COVID-19-adapted FLU-PRO Plus is a questionnaire that assesses the severity of symptoms in participants with COVID-19 across six body systems: nose, throat, eyes, chest/respiratory, gastrointestinal, and body/systemic. Each domain scores range from 0 (symptom free) to 4 (very severe symptoms). A higher score indicates increased symptom severity. Alleviation is defined as symptom scores of 0 (absent) or 1 (mild). Time to alleviation of baseline COVID-19 symptoms is defined (in days) as: First Date of the two consecutive dates achieving alleviation - First dose Date + 1. If a participant had not achieved symptom alleviation at last FLU-PRO Plus assessment or early discontinuation of study, the participant was censored at last FLU-PRO Plus assessment date. Participants in the Full Analysis Set with available data were analyzed. 99999 indicates that not enough event to estimate Median and Inter-Quartile Range.

The worsening after alleviation of baseline COVID-19 symptoms is defined as for a participant who has achieved alleviation of baseline COVID-19 symptoms, if symptoms scored as 2 or higher at baseline is scored as 2 or higher postbaseline after achieved alleviation, or symptoms scored as 1 at baseline are scored as 1 or higher postbaseline after achieved alleviation. The COVID-19-adapted FLU-PRO Plus was used. It is a questionnaire that assesses the severity of symptoms in participants with COVID-19 across six body systems: nose, throat, eyes, chest/respiratory, gastrointestinal, and body/systemic.
