Brief Summary:
This study will compare two drugs (hydroxychloroquine and azithromycin) to see if hydroxychloroquine is better than azithromycin in treating hospitalized patients with suspected or confirmed COVID-19.

Condition or disease Intervention/treatment Phase
COVID-19 Drug: Hydroxychloroquine Drug: Azithromycin Phase 2

Layout table for study information
Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 85 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Hydroxychloroquine vs. Azithromycin for Hospitalized Patients With Suspected or Confirmed COVID-19 (HAHPS): A Prospective Pragmatic Trial
Actual Study Start Date : March 30, 2020
Actual Primary Completion Date : July 1, 2020
Actual Study Completion Date : January 1, 2021


Arm Intervention/treatment
Experimental: Hydroxychloroquine Drug: Hydroxychloroquine
Patients in the hydroxychloroquine arm will receive hydroxychloroquine 400 mg by mouth twice daily for 1 day, then 200 mg by mouth twice daily for 4 days (dose reductions for weight < 45 kg or GFR (glomerular filtration rate)<50ml/min). For patients < 45kg, doses will be halved. For patients with GFR<50ml/min, the final dose of hydroxychloroquine will not be administered. If the patient has already received hydroxychloroquine prior to randomization (no more than 2 days), the prior doses will count toward the 5-day total.

Active Comparator: Azithromycin Drug: Azithromycin
Patients in the azithromycin arm will receive azithromycin 500 mg on day 1 plus 250 mg daily on days 2-5 (may be administered intravenously per clinician preference). If the patient has already received azithromycin prior to randomization (no more than 2 days), the prior doses will count toward the 5-day total.




Primary Outcome Measures :
  1. COVID Ordinal Outcomes Scale at 14 Days [ Time Frame: Assessed once on day 14 after enrollment (enrollment is day 0) ]
    Improvement of clinical condition of the patient defined by the COVID-19 WHO ordinal Outcomes score. This scale reflects a range from uninfected to dead, where 0 is "no clinical or virological evidence of infection", 1 is "no limitation of activities", 2 is "limitation of activities", 3 is "hospitalized, no oxygen therapy", 4 is "oxygen by mask or nasal prongs", 5 is "non-invasive ventilation or high-flow oxygen", 6 is "intubation and mechanical ventilation", 7 is "ventilation + additional organ support - pressors, RRT (renal replacement therapy), ECMO (extracorporeal membrane oxygenation)", and 8 is "death".


Secondary Outcome Measures :
  1. Hospital-free Days at 28 Days [ Time Frame: Admission (day 1) to 28 days after admission (day 28) ]
    Calculated as number of days patient not in hospital

  2. Ventilator-free Days at 28 Days (Number of Days Patient Not on a Ventilator) [ Time Frame: Admission (day 1) to 28 days after admission (day 28) ]
    Calculated as number of days that patient is not on a ventilator up to day 28 days after admission

  3. ICU-free Days at 28 Days [ Time Frame: Admission (day 1) to 28 days after admission (day 28) ]
    Calculated as number of days patient not in an ICU

  4. Time to a 1-point Decrease in the WHO Ordinal Recovery Score [ Time Frame: Admission (day 1) to 14 days after admission (day 14) ]
    Time to 1-point decrease in the WHO ordinal recovery score is defined as the number of days until the ordinal outcome score drops by 1 relative to baseline on the 8-point WHO COVID Ordinal Outcomes scale, which reflects a range from uninfected to dead, where 0 is "no clinical or virological evidence of infection", 1 is "no limitation of activities", 2 is "limitation of activities", 3 is "hospitalized, no oxygen therapy", 4 is "oxygen by mask or nasal prongs", 5 is "non-invasive ventilation or high-flow oxygen", 6 is "intubation and mechanical ventilation", 7 is "ventilation + additional organ support - pressors, RRT (renal replacement therapy), ECMO (extracorporeal membrane oxygenation)", and 8 is "death".
