About this study

Official title: Prophylaxis With Chloroquine in Health Personnel Exposed to Infection With Coronavirus Disease 2019 (COVID-19)

The purpose of this study is to assess the efficacy and safety of chloroquine prophylaxis on the incidence of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infections in healthcare workers exposed to patients with confirmed Coronavirus Disease 2019 (COVID-19)

Read the detailed description

Single arm study in which healthcare workers were actively invited to participate. Possible participants were asked to complete a questionnaire to determine eligibility for study entry and to identify risk factors for infection, severe infection, or adverse events associated with chloroquine use.

Volunteers who meet the eligibility requirements received chloroquine 150mg base at days 0, 15, 30, 45, 60, 75. Cumulative incidence and incidence rate of COVID-19 at days 30,60 and 90 were calculated. Presence of Immunoglobulin G (IgG) antibodies against SARS-Cov-2 was evaluated at the beginning, at the end and at any moment if they become infected with this virus.

In addition, patients were asked to complete a survey evaluating adverse effects and COVID-19 symptoms at day 0 and weeks 2,4,6,8,10, and 12.

Model description
Single arm study in which healthcare workers were actively invited to participate. After verifying volunteer's eligibility through a survey that evaluated the presence of COVID-19 symptoms (primary efficacy outcome), 150 mg chloroquine base was dispensed in site by a pharmaceutical chemist at days 0, 15, 30, 45, 60, and 75. Questions regarding adverse drugs reactions (safety outcome) were included in the survey after the first dose was administered. Participants who discontinued chloroquine were followed up until study completion.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Chloroquine in people with Covid19, run by Fundacion Clinica Valle del Lili at 1 site in Colombia.

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 1 inclusion and 6 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 7 Oct 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 Colombia. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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?

COVID-19 infection (time frame: Day 15). The study lists 6 primary outcomes in all. 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 NCT04627467, which also lists 28 linked publications.

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 7 Oct 2021.
