Design outcomes

Primary

MeasureTime frame
Main Objective: The aim of the study is to evaluate whether the therapy with chloroquine phosphate (CQ, in combination with telemedical approach) in addition to standard care is effective and safe in reducing composite endpoint of COVID-19-related hospitalization or all cause death in 15-day observation, in ambulatory patients with SARS-SoV-2 infection (in comparison with subjects not treated with CQ but receiving standard care and supervised telemedically).;Secondary Objective: Not applicable;Primary end point(s): Hospitalisation due to COVID-19 or death for any cause in 15-day observation (up to and including the 15th study);Timepoint(s) of evaluation of this end point: Day 15 (the day after the 14-day treatment cycle)

Secondary

MeasureTime frame
Secondary end point(s): Secondary endpoints related to effectiveness: 1. no symptoms of COVID-19 in 15-day observation: o Fever o Tachycardia o Abnormal saturation o Cough o Dyspnea at rest o Dyspnea in small life activities o Chest compressions o Chest pain during inhalation/expiration o Headache o Sinus pain o Cold o Sore throat o General weakness o Pain or muscle weakness o Appetite deterioration o Olfactory deprivation o Flavour depreciation o Nausea or vomiting o Diarrhoea o Dizziness 2. No symptoms of COVID-19 in a 42-day or shorter observation for patients who did not have 42 days at the end of 15-day observation for the last patient on: o Fever o Tachycardia o Abnormal saturation o Cough o Dyspnea at rest o Dyspnea in small life activities o Chest compressions o Chest pain during inhalation/expiration o Headache o Sinus pain o Cold o Sore throat o General weakness o Pain or muscle weakness o Appetite deterioration o Olfactory deprivation o Flavour depreciation o Nausea or vomiting o Diarrhoea o Dizziness 3. No hospitalisation due to COVID-19 or death for any cause in a 42-day or shorter observation for patients for whom the 42-day or shorter observation has not passed at the end of the 15-day observation for the last patient included 4. No death for any cause in a 42-day or shorter observation for patients for whom 42 days have not passed at the end of a 15-day observation for the last patient included Secondary safety related endpoints: 1.Do not discontinue the drug due to side effects in 15-day observation. ;Timepoint(s) of evaluation of this end point: Days 1-1
