Primary Outcome Measures :
  1. Incidence of Treatment-Emergent Adverse Events to Determine Single Dose of CPI-006 That is Safe in Patients with COVID-19 [ Time Frame: Up to 30 days after dose of CPI-006. ]
    Incidence of adverse events (including serious adverse events and dose limiting toxicities).

  2. Immunoglobulin Anti-SARS CoV-2 Levels [ Time Frame: Baseline and Day 28. ]
    Measure changes in serum or plasma immunoglobulin anti-SARS CoV-2 levels.


Secondary Outcome Measures :
  1. Negative Nasal Swab Polymerase Chain Reaction (PCR) SARS CoV-2 Viral Tests [ Time Frame: Baseline to two consecutive negative nasal swab PCR SARS CoV-2 viral tests (separated by at least 48 hours). ]
    Time to two consecutive negative nasal swab PCR SARS CoV-2 viral tests.

  2. Duration of symptoms [ Time Frame: Up to 24 weeks after dose of CPI-006. ]
    Duration of COVID-19 related symptoms.

  3. Time to discharge [ Time Frame: Up to 24 weeks after dose of CPI-006. ]
    Time to discharge from hospital.

  4. Rate of medical procedures [ Time Frame: Up to 24 weeks after dose of CPI-006. ]
    Rate of medical procedures during hospitalization.

  5. Difference in changes in serum/plasma immunoglobulin anti-SARS CoV-2 levels [ Time Frame: Baseline and visits through Day 28. ]
    Difference between Active Arm and Control Arm patients in terms of changes in serum or plasma immunoglobulin anti-SARS CoV-2 levels.
