About this study
Official title: Multicentric Pragmatic Randomized Controled Trial to Evaluate the Efficacy Chloroquine or Hydroxychloroquine for Five Days in Treating Pneumonia Caused by SARS-Cov-2 - COVID-19
Facing the challenge of finding an efficient treatment for COVID-19, the viral pneumonia caused by the Coronavirus SARS-Cov-2, this study intended to test if Chloroquine or Hydroxychloroquine, two drugs with strong in-vitro antiviral role proven by numerous studies and with a well defined safety profile established, for efficacy in treating COVID-19 and improving an ordinal primary outcome composed by a 9-levels scale, which was recomended by the World Health Organization.
Read the detailed description
This is a Phase 3, Pragmatic, Multicentric Randomized Controled Trial of efficacy to test the effect of either Chloroquine or Hydroxychloroquine for 5 days in the recomended dose standardized by brazilian Ministry of Health.
Patients were randomized (1:1) using stratified randomization by hospital and severity at the moment of randomization (stipulated by use of mechanical ventilation or not) into two arms: Intervention and Control. Intervention group recieved a loading dose of 900mg of Chloroquine or 800mg of Hydroxycloroquine in the first day, followed by 450mg of chloroquine of 400mg of hydroxychloroquine. Primary and secondary outcomes were evaluated on the 5th, 7th, 10th, 14th, 28th day after randomization.
Although the outcomes presented in the latest version were updated late on ClinicalTrials.org, on October 23, 2020, these outcomes were already present in the trial protocol approved by the Brazilian National Commission for Ethics in Research on April 8, 2020 (approval number: 3960331) and amending the protocol, approved by the same National Commission on May 25, 2020 (approval number: 4044848)

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Chloroquine and Hydroxychloroquine in people with COVID and COVID-19, run by Centro de Estudos e Pesquisa em Emergencias Medicas e Terapia Intensiva 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: finished, as of the sponsor's last update on 12 May 2021. 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?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
World Health Organization (WHO) 9-levels ordinal scale (from 0-8) (time frame: 14 days after randomization). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT04420247, which also lists 1 linked publication.
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 12 May 2021.
