Brief Summary:
This study explores whether patients acutely hospitalized may have shorter hospitalization and fewer admittances at Intensive Care Units by treatment with azithromycin and hydroxychloroquine.

Condition or disease Intervention/treatment Phase
Virus Diseases Infection Viral Corona Virus Infection Drug: Azithromycin Drug: Hydroxychloroquine Drug: Placebo oral tablet Phase 2

Detailed Description:

In the ongoing coronavirus pandemic, COVID-19, that arose in Wuhan China, there is still sparse data in the course, risk of various complications, and in particular how patients who are hospitalized are best treated to ensure high survival and short hospitalization. Despite the rapid spread of the disease globally, there is no solid data yet to recommend any specific treatments, which is why symptomatic, organ supportive therapy including respiratory therapy in acute pulmonary failure is recommended. There has been reported a high incidence of bacterial super-infections in patients with COVID-19. Patients with COVID-19 also have a higher risk of dying because of septic shock. Thus, there is an urgent need for treatment that can improve the patient's chance of the shortest hospitalization possible, and treatment that can lower the risk of secondary infection and death.

This is a randomized, placebo-controlled, double-blinded multi-center trial evaluating the effect of azithromycin and hydroxychloroquine treatment in patients with COVID-19 during hospitalization. The aim of the study is to investigate whether the treatment can shorten hospitalization, reduce the risk of non-invasive ventilation, admittance to Intensive Care Units and death.

Primary Outcome Measures :
  1. Number of Days Alive and Discharged From Hospital Within 14 Days [ Time Frame: 14 days ]

Secondary Outcome Measures :
  1. Categorization of Hospitalization Status [ Time Frame: 14 days ]

    The patient will be categorized into one of the following 8 categories depending on status of their hospitalization:

    1. Dead (yes/no)
    2. Hospitalized and receiving mechanical ventilation or ExtraCorporalMembraneOxygenation (ECMO) (yes/no)
    3. Hospitalized and receiving Non-invasive ventilation or "high-flow oxygen device" (yes/no)
    4. Hospitalized and given oxygen supplements different from (2) and (3) (yes/no)
    5. Hospitalized and without oxygen treatment, but receiving other treatment (both related to COVID-19 or other) (yes/no)
    6. Hospitalized for observation (yes/no)
    7. Discharged from hospital with restriction of activity level (yes/no)
    8. Discharged from hospital without any restrictions of activity level (yes/no)

    Only one category can be "yes".

  2. Length of Stay in ICU [ Time Frame: 14 days ]
    Length of stay in intensive care unit.

  3. Number of Participants on Non-invasive Ventilation (NIV) During Hospitalization [ Time Frame: 14 days ]
  4. Mortality [ Time Frame: 30 days ]
  5. Length of Hospitalization [ Time Frame: 14 days ]
  6. Days Alive and Discharged From Hospital [ Time Frame: 30 days ]
  7. Mortality [ Time Frame: 90 days ]
  8. Mortality [ Time Frame: 365 days ]
  9. Number of Readmissions (All Causes) [ Time Frame: 30 days ]
  10. Number of Days Using Non-invasive Ventilation (NIV) [ Time Frame: 14 days ]
    Number of days using non-invasive ventilation (NIV) if on NIV during hospitalization.

  11. Change in Patient's Oxygen Partial Pressure [ Time Frame: 4 days ]
    PaO2 measured in arterial puncture at baseline and 4 days.

  12. Change in Patient's Carbondioxide Partial Pressure [ Time Frame: 4 days ]
    PaCO2 measured in arterial puncture at baseline and 4 days.

  13. Change of pH in Blood [ Time Frame: 4 days ]
    pH measured in arterial puncture at baseline and 4 days.

  14. Time for no Oxygen Supplement (or Regular Oxygen Supplement "LTOT") [ Time Frame: 14 days ]
    Time for no oxygen supplement (or regular oxygen supplement "LTOT") if on oxygen during admission.
