Brief Summary:
This is an exploratory study to evaluate the efficacy of hydroxychloroquine (400 mg BID on D1 and 400 mg/day on D2 to D5) and azithromycin (500 mg/ 5 days) to treat moderate to severe COVID-19 pneumonia.

Condition or disease Intervention/treatment Phase
COVID-19 Drug: Hydroxychloroquine Sulfate Drug: Azithromycin Tablets Early Phase 1

Detailed Description:

This is an exploratory, open label, multi-center study to evaluate the efficacy of hydroxychloroquine (HCQ) (400 mg BID on D1 and 400 mg/day on D2 to D5) and azithromycin (AZT) (500 mg/ 5 days) to treat moderate to severe COVID-19 pneumonia.

We aim to demonstrate decrease in hospital related complications among patients who are hospitalized with moderate or severe COVID-19 by treating them with HCQ and AZT on top of standard care compared to patients who receive standard care only.

Patients hospitalized with confirmed diagnosis of COVID-19 will receive the treatment.

Patients that do not fulfill the inclusion/exclusion criteria or that is not willing to participate in the study will be invited to consent the use of their data as part of a "control" group.
