Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Number of Participants With Grade 3 and Grade 4 Adverse Events (AEs) Through Day 35
Time Frame: Up to Day 35
An AE is any untoward medical occurrence that occurs in a participant. An AE can be any unfavorable and unintended sign (including abnormal laboratory findings), symptom, or disease temporally associated with treatment, whether considered related to the product. AEs may include the onset of a new illness or undesirable medical condition or the exacerbation of pre-existing medical conditions. AE severity was graded as Grade 3 (Severe) and Grade 4 (Potentially Life-threatening) per the specific toxicity grading by the Division of Acquired Immunodeficiency Syndrome (DAIDS) AE Grading Table.
Up to Day 35
Number of Participants With AEs Resulting in Study Intervention Discontinuation Through Day 35
Time Frame: Up to Day 35
An AE is any untoward medical occurrence that occurs in a participant. An AE can be any unfavorable and unintended sign (including abnormal laboratory findings), symptom, or disease temporally associated with treatment, whether considered related to the product. AEs may include the onset of new illness or undesirable medical condition or the exacerbation of pre-existing medical conditions.
Up to Day 35
Number of Participants With Serious Adverse Events Through Day 35
Time Frame: Up to Day 35
A serious AE is any untoward medical occurrence or effect, that, at any dose: results in death; is life-threatening; requires hospitalization or prolongation of existing hospitalization; results in persistent or significant disability or incapacity; is an important medical event that may not be immediately life-threatening or result in death or hospitalization but may jeopardize the participant or may require intervention to prevent one of the other outcomes.
Up to Day 35
Number of Participants Who Progressed to Moderate or Severe Disease or Higher Based on the Gates MRI Ordinal Scale Through Day 28
Time Frame: Up to Day 28
Participants who progressed to a moderate or severe disease category or higher (Bill & Melinda Gates Medical Research Institute [Gates MRI] ordinal scale ≥3) are reported. Gates MRI scale scores are assessed on a 7-point scale: 1=Asymptomatic/symptoms similar to pre-COVID-19 status; 2=Mild; 3=Moderate or severe; 4=Critically ill; 5=Critically ill with invasive mechanical ventilation or extrapulmonary complication; 6=Critically ill with Extra-Corporeal Membrane Oxygenation (ECMO); 7=Death.

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Median Time to Disease Resolution Based on Symptoms Resolution Through Day 28
