- Proportion of patients with onset of severe acute respiratory syndrome (SARS) [ Time Frame: 7 days after randomization ]Evaluate if CQ diphosphate prevents the onset of SARS in patients on intervention group through standardized questionnaires.
- Mortality rate [ Time Frame: after randomization, up to 28 days ]Mortality rate between intervention and placebo group on days 7, 14, and 28 after randomization
- Number of participants in need of intensive care support [ Time Frame: during and after intervention, up to 28 days ]Proportion of participants in need and duration of intensive care support after randomization
- Viral concentration [ Time Frame: After randomization, up to 7 days ]Viral load change in blood and oropharyngeal swab samples
- Cumulative incidence of serious adverse events [ Time Frame: During and after intervention, up to 28 days ]Incidence of serious adverse events during and after treatment
- Cumulative incidence of grade 3 and 4 adverse events [ Time Frame: During and after intervention, up to 28 days ]Incidence of grade 3 and 4 adverse events during and after treatment
- Proportion of patients with discontinued treatment [ Time Frame: after randomization, up to 28 days ]proportion of discontinuation or temporary suspension of treatment (for any reason)
- Incidence of cardiac lesions [ Time Frame: after randomization, up to 120 days ]proportion of patients with increased levels of troponin I
- Incidence of cardiac disfunctions [ Time Frame: after randomization, up to 120 days ]proportion and magnitude of QTcF interval increases higher than 500ms
