About this study
Official title: Open Label, Multicentric, Non Randomized, Exploratory Clinical Trial to Assess the Efficacy and Safety of Hydroxychloroquine and Azithromycin for the Treatment of Mild Acute Respiratory Syndrome (COVID-19) Caused by SARS-CoV-2 Virus
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.
Read the detailed description
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.

Questions about this trial
What is this clinical trial studying?
A Early Phase 1 study testing Hydroxychloroquine Sulfate and Azithromycin Tablets in people with Covid-19, run by Azidus Brasil at 1 site in Brazil.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: paused, as of the sponsor's last update on 4 Nov 2022. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Brazil. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change in Clinical Condition (time frame: 28 days). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 4 Nov 2022.
