EVALUATION OF THE EFFICACY OF THE HYDROXYCHLOROQUINE-AZITHROMYCIN COMBINATION IN THE IN THE PREVENTION OF COVID-19 RELATED SDRA

Phase 3

Conditions
Sars-CoV-2, Community-Acquired Pneumonia,COVID-19

Registration Number
NCT04347512
Lead Sponsor
University Hospital, Strasbourg, France
Brief Summary

Since end of December, a new coronavirus, close to the 2002 SARS coronavirus, cause serious pneumonias throughout world. There is currently no strong evidence of an efficient specific treatment. Hydroxychloroquine is an old chloroquine-derived drug, prescribed for auto-immune disorders. It has shown efficacy against Sars-CoV-2 in vitro. Some studies showed that Hydroxychloroquine might improve the clinical status of Sars-CoV-2 infected patients. Azithromycin is a macrolide antibiotic, with immunomodulatory properties. Adding Azithromycin to a hydroxychloroquine-based treatment showed an apparent accelerated viral clearance in infected patients. This study wants to evaluate the clinical impact of adding Azithromycin to Hydroxychloroquine in the treatment of Sars-CoV-2 pneumonia

GroupInterventionDescription
Hydroxychloroquine and AzithromycinHydroxychloroquine and azithromycin treatment arm.Hydroxychloroquine is given for 5 days, with a loading dose of 400 mg qd at D1, and 200 mg qd for the next 4 days (D2-D5). Azithromycin is given for 5 days, with a loading dose of 500 mg at D1, and 250 mg for the next 4 days. Standard of care is also prescribed (oxygen therapy, analgesics, antipyretics, anticoagulant drug, etc) In case of moderate renal failure (glomerular filtration rate between 30 and 60 mL/min/m²), hydroxychloroquine dosage are lowered by half.
ControlControl armThe patient is given antibiotics only. Standard of care is also prescribed (oxygen therapy, analgesics, antipyretics, anticoagulant drug, etc).

Primary Outcome Measures
NameTimeMethod
Rate of patients reaching a significant hypoxemia, in each arms.From day 0 to day 7

A significant hypoxemia is an arterial partial pressure of oxygen of less than 60 mmHg despite an oxygen flow of more than 6 L/min, patient at rest.
