Primary Outcome Measures :
  1. Change From Baseline to Day 8 in Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) Viral Shedding [ Time Frame: Baseline and Day 8 ]
    SARS-CoV-2 viral shedding was measured by reverse transcription-quantitative polymerase chain reaction (RT-qPCR) in nasopharyngeal swab samples.


Secondary Outcome Measures :
  1. Time-Weighted Average Change in SARS-CoV-2 Viral Shedding From Baseline to Day 15 [ Time Frame: Baseline and Day 15 ]
  2. Change in SARS-CoV-2 Viral Shedding From Baseline to Day 15 [ Time Frame: Baseline and Day 15 ]
    SARS-CoV-2 viral shedding was measured by RT-qPCR in nasopharyngeal swab samples

  3. Time to Negative RT-qPCR in All Tested Samples [ Time Frame: From Baseline up to Day 21 ]
    The negative RT-qPCR is defined as the value that is below the lower limit of detection

  4. Percentage of Participants Who Required Hospitalization Due to Worsened COVID-19 [ Time Frame: Baseline up to End of Study (EOS) /174 Days ]
  5. Time to Resolution of All COVID-19-Related Symptoms [ Time Frame: Baseline up to EOS /174 Days ]
  6. All-Cause Mortality at Day 29 [ Time Frame: Day 29 ]
    Number of participants that died by Day 29

  7. Number of Participants With Treatment-emergent Adverse Events (TEAEs) and Serious Adverse Events (SAEs) [ Time Frame: Up to 174 days ]
  8. Maximum Observed Plasma Concentration (Cmax) of BGB-DXP593 [ Time Frame: Day 1 (pre-dose, End of Infusion) Days 3, 8, 15, 29, and End of study visit (up to174 days) ]
  9. Area Under the Plasma Concentration-time Curve (AUC) of BGB-DXP593 From Time 0 to Day 29 [ Time Frame: Day 1 (pre-dose, End of Infusion) Days 3, 8, 15, and 29 ]
  10. Area Under the Plasma Concentration-time Curve (AUC) of BGB-DXP593 [ Time Frame: Day 1 (pre-dose, End of Infusion) Days 3, 8, 15, 29, and End of study visit (up to 174 days) ]
    AUClast : AUC from time zero to the time of the last quantifiable concentration AUCinf: AUC from zero to infinite time with extrapolation of the terminal phase

  11. Time to Reach Cmax (Tmax) of BGB-DXP593 [ Time Frame: Day 1 (pre-dose, End of Infusion) Days 3, 8, 15, 29, and End of study visit (up to 174 days) ]
  12. Terminal Half-Life (t1/2) of BGB-DXP593 [ Time Frame: Day 1 (pre-dose, End of Infusion) Days 3, 8, 15, 29, and End of study visit (up to 174 days) ]
  13. Clearance (CL) of BGB-DXP593 [ Time Frame: Day 1 (pre-dose, End of Infusion) Days 3, 8, 15, 29, and End of study visit (up to 174 days) ]
  14. Volume of Distribution During the Terminal Phase (Vz) of BGB-DXP593 [ Time Frame: Day 1 (pre-dose, End of Infusion) Days 3, 8, 15, 29, and End of study visit (up to 174 days) ]
  15. Number of Participants With Anti-drug Antibodies (ADAs) to BGB-DXP593 [ Time Frame: Day 1 (pre-dose) Days 15, 29, and End of study visit (up to 174 days) ]
