Prevention of SARS-CoV-2 in Hospital Workers s Exposed to the Virus

Phase 3
Completed
Conditions
SARS-CoV-2 Infection
Interventions
Registration Number
NCT04344379
Lead Sponsor
Assistance Publique - Hôpitaux de Paris
Brief Summary

The Investigators propose to set up a preventive trial of infection in hospital workers at risk of coronavirus infection by comparing the rate of SARS-Cov-2 infection in a population of negative SARS-Cov-2 hospital workers receiving preventively azithromycin, hydroxychloroquine or a Placebo

Detailed Description

Randomized clinical trial with 3 arms : hydroxychloroquine group, 300 subjects/azithromycin group, 300 subjects/ placebo of hydroxychloroquine group, 300 subjects. Hospital workers workers will be invited to participate in the study in each hospital and they will be included after giving their consent, assessment of their eligibility criteria, endonasal PCR and serolology at baseline. They will be randomized in one of the 3 arms, receive their treatment and will be followed by physical visit (at Day 2, Day 5, Day 15, Day 28) and by phone (at Day) 40 days with clinical data collection (tolerance and clinical signs of infection). At the end of treatment, another serology will be collected.
