Brief Summary

Coronavirus (COVID-19) is a somewhat new and recognized infectious disease that is now spreading to several countries in the world, including Brazil. Hydroxychloroquine and azithromycin may be useful for treating those patients.

COALITION I study aims to compared standard of care, hydroxychloroquine plus azithromycin and hydroxychloroquine monotherapy for treatment of hospitalized patients with COVID-19.

COALITION I will recruit 630 patients with infection by COVID-19 (210 per arm). Ordinal endpoint of status at 15 days will be the primary endpoint.

Detailed Description

The current pandemic associated with coronavirus disease 2019 (COVID-19) represents a major global health challenge. There are no effective therapies for the management of COVID-19 that have been proven to improve clinical outcomes in this high-risk group of patients. Hydroxychloroquine and its combination with azithromycin have been suggested to improve viral clearance, but its effect on clinical outcomes remains uncertain.

This is an open-label pragmatic multicentre randomized (concealed) clinical trial of 7 days of hydroxychloroquine (400 mg BID) plus azithromycin (500 mg once daily), hydroxychloroquine 400 mg BID, or standard of care for moderately severe hospitalized patients with suspected or confirmed COVID-19 (in-patients with up to 4L/minute oxygen supply through nasal catheter). Patients are randomized in around 50 recruiting sites (630 patients with confirmed COVID-19; 1:1:1; 210 patients per arm).

The primary endpoint is a 7-level ordinal scale measured at 15-days: 1) not hospitalized, without limitations on activities; 2) not hospitalized, with limitations on activities; 3) hospitalized, not using supplementary oxygen; 4) hospitalized, using supplementary oxygen; 5) hospitalized, using high-flow nasal cannula or non-invasive ventilation; 6) hospitalized, on mechanical ventilation; 7) death. Secondary endpoints are the ordinal scale at 7 days, need for mechanical ventilation and rescue therapies during 15 days, need of high-flow nasal cannula or non-invasive ventilation during 15 days, length of hospital stay, in-hospital mortality, thromboembolic events, occurrence of acute kidney injury, defined as an increase in creatinine above 1.5 times the baseline value and number of days free of respiratory support at 15 days. Secondary safety outcomes include prolongation of QT interval on electrocardiogram, ventricular arrhythmias, and liver toxicity. The main analysis will consider all patients with confirmed COVID-19 in the groups they were randomly assigned.
