University Hospital, Montpellier

Brief Summary:
Double blinded randomized clinical trial designed to evaluate the efficacy and safety of hydroxychloroquine combined with azithromycin compared to hydroxychloroquine monotherapy in patients hospitalized with confirmed COVID-19 pneumonia.

Condition or disease Intervention/treatment Phase
Coronavirus Infection Pneumonia, Viral Drug: Hydroxychloroquine + placebo Drug: hydroxychloroquine + azithromycin Phase 2 Phase 3

Detailed Description:
The multi-centre COVIDOC study will evaluate the efficacy and safety of the use of hydroxychloroquine (10 days) combined with azithromycin (5 days) compared to hydroxychloroquine (10 days) in the the clinical evolution by the ordinal scale of 7 points in adults hospitalized outside Intensive care unit with pneumonia caused by infection by the SARS-CoV2 virus in France.

Primary Outcome Measures :
  1. Time to clinical improvement of at least 1 level on the ordinal scale between Day 1 (day of the first administration of study drug) to Day 11 (day after last day of treatment). [ Time Frame: up to Day 11 ]
    Evaluation of the clinical status of patient defined by the Ordinal Scale of 7 points (score range from 1 to 7 , with 7 being the worst score)

Secondary Outcome Measures :
  1. Clinical status assessed by ordinal scale [ Time Frame: up to Day 29 ]
    Evaluation of the clinical status of patient defined by the Ordinal Scale of 7 points at day 15 and day 29

  2. transfer to ICU [ Time Frame: up to Day 29 ]
    Necessity for transfer to Intensive care unit

  3. Length of hospital day [ Time Frame: up to Day 29 ]
    days from admission to hospital discharge

  4. Hospital Mortality [ Time Frame: Day 29 ]
    incidence of all-cause mortality

  5. Need to Mechanical Ventilation [ Time Frame: up to Day 29 ]
    Need to mechanical ventilation

  6. Occurence of grade 3-4 adverse event [ Time Frame: up to Day 29 ]
    adverse reactions

  7. QTc Lengthening [ Time Frame: up to Day 11 ]

  8. Evolution of pulmonary CT scan images [ Time Frame: up to Day 11 ]
    Thoracic CT scan : number and size of ground-glass opacifications on day 1 and day 11 Two independent pulmonary imagery experts will assess abnormalities according to a standardized framework
