Brief Summary:
The purpose of this study is to assess the efficacy of N-acetylcysteine (NAC) in preventing those with mild or moderate COVID-19 from progressing to severe disease

Condition or disease Intervention/treatment Phase
COVID Sars-CoV2 SARS-Associated Coronavirus as Cause of Disease Classified Elsewhere Oxidative Stress Drug: N-acetylcysteine Phase 2

Detailed Description:

After being informed of the study and potential risks and benefits, patients meeting eligibility requirements will be randomized to receive oral N-acetylcysteine (NAC) as follows:

Inpatients:

  • N-acetylcystine (NAC) 25 mg/kg PO (rounded up to the nearest 600 mg) q4hrs until discharge
  • N-acetylcysteine (NAC) 1200 mg PO BID x 1 week post-discharge

Outpatients:

- N-acetylcysteine (NAC) 2400 mg PO x 1 then 1200 mg PO BID x 2 weeks

Arm Intervention/treatment
Active Comparator: NAC
Patients receiving N-acetylcysteine (NAC)
Drug: N-acetylcysteine
Oral formulation: 600 mg capsules of N-acetylcysteine
Other Name: NAC, acetylcysteine, N-acetyl-L-cysteine, NALC

No Intervention: Control
Patients not receiving N-acetylcysteine (NAC)



Primary Outcome Measures :
  1. Decrease in Respiratory Rate [ Time Frame: First hour after first dose of NAC ]
    Decrease in dyspnea measured by respiratory rate (RR)

  2. Hospital length of stay (LOS) [ Time Frame: Through study completion, average 9 months ]
    Hospital LOS for admitted patients

  3. Need for mechanical ventilation [ Time Frame: Through study completion, average 9 months ]
    Whether a patient needed mechanical ventilation (intubation)

  4. Length of time intubated [ Time Frame: Through study completion, average 9 months ]
    If intubated, how long needing mechanical ventilation

  5. Need for hospitalization [ Time Frame: Through study completion, average 9 months ]
    Outpatients on NAC needing admission to the hospital

  6. Recovery disposition [ Time Frame: Through study completion, average 9 months ]
    Whether outpatients continued to recover as outpatients; whether admitted patients were managed on medical floors or level of care increased to ICU level of care; whether patients expired
