Official Title
Efficacy of Azithromycin-associated Hydroxychloroquine Therapy Given in General Practice in Early-stage Disease in COVID-19 Patients: Randomized Controlled Trial: MG-COVID
Brief Summary

Hydroxychloroquine, a derivative of chloroquine (an antimalarial drug) with a weak immunosuppressive effect, is prescribed by some teams alone or in combination with azithromycin. No randomized controlled trials have demonstrated its efficacy, particularly in primary care in the early stages of the disease. However, currently available data suggest better efficacy if treatment is given early in the disease, before symptoms worsen. To date, the majority of COVID-19 patients treated in outpatient care, particularly in general practice, represent the majority of COVID-19 patients. It is essential to evaluate, in primary care, the efficacy and safety of hydroxychloroquine combined with azithromycin in Covid-19 patients in order to be able to implement this therapeutic strategy as soon as the first symptoms appear. We realize a randomized, controlled, open superiority trial, in 2 parallel groups (ratio 1:1).The main objective is to assess the efficacy of Hydroxychloroquine combined with azithromycin in COVID-19 patients in primary care, in add-on to standard of care, on unfavorable outcome defined by the onset of at least one of the following between D0 and D14: hospitalization, death or percutaneous O² saturation ≤ 92% in ambient air.

Detailed Description

Randomized, controlled, open superiority trial, in 2 parallel groups (ratio 1:1).

Eligible consecutive patient will be offered to take part in the trial during a visit to thier GP for COVID symptoms. After verification of eligibility criteria and written informed consent, a nasopharyngeal swab, an ECG and a blood sampled (kalaemia, magnesemia and calcemia) will be performed.

Patient with SARS-CoV-2 PCR positive result and still fulfilling eligibility criteria will be randomized on day2 (D2) through a web-based allocation system, following a computer generated allocation list, stratified on center and existence of any comorbidity, to experimental or control group. Patients without confirmation of SARS-CoV-2 infection on PCR will not continue the trial. Both groups patients will have a paper-based diary to record their daily symptoms and drug intake. A clinical follow-up will be done by the GP at D5, D8, D14 and D28.The main analysis population will be in intention to treat. An intermediate efficacy analysis is planned when 50% of patients have reached D14.

Two hundred consecutive patients (from pre-identified centers) will be included in an ancillary virological study to assess evolution of viral load at D8 and D14. For these patients all nasopharyngeal swab will be sent to a centralised lab at Pitié-Salpêtrière Hospital.
