Azidus, the CRO hired for this study by Prevent Senior has lost the interest to conduct this study.

This is an exploratory study to evaluate the efficacy of hydroxychloroquine (400 mg BID on D1 and 400 mg/day on D2 to D7) and azithromycin (500 mg/ 5 days) to treat mild ambulatory COVID-19 patients.

This is an exploratory study to evaluate the efficacy of hydroxychloroquine (400 mg BID on D1 and 400 mg/day on D2 to D7) and azithromycin (500 mg/ 5 days) to treat mild ambulatory COVID-19 patients.

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

Ambulatory patients on day 3 of symptoms and 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.

Inclusion Criteria:

1. Informed consent from patient or legal representative.

2. Male or female, and:

   1. aged ≥ 70 years; or
   2. aged < 70 with associated risk factors (chronic obstructive pulmonary disease; heart failure, immunosuppressed, obesity (BMI ≥ 35) uncontrolled diabetes and uncontrolled systemic arterial hypertension)

3. One or more mild symptoms characteristic of COVID-19 for 3 days, such as fever, cough and signs of respiratory distress, which do not require hospitalization.

Exclusion Criteria:

1. Participating in another RCT in the past 12 months;
2. Known allergy to HCQ or chloroquine
3. Any contraindication to HTC or AZT, including retinopathy and prolonged QT,
4. Severely reduced LV function
5. Severely reduced renal function;
6. Pregnancy or breast feeding
7. Any other clinical condition which, in the opinion of the principal investigator, would not allow safe completion of the protocol and safe administration of the investigational products

It is believed that after the data analysis and presentation to the National Commission on Research Ethics, all data of the study will become public.
