August 31, 2020 updated by: Ann Chauffe, Louisiana State University Health Sciences Center in New Orleans

Hydroxychloroquine as Primary Prophylaxis for COVID-19 in Healthcare Workers (HCQPreP)

This a double-blind, randomized, placebo-controlled clinical trial to determine if primary prophylaxis with hydroxychloroquine in healthcare workers reduces symptomatic COVID-19 infection. Healthcare workers will be randomized at a 1:1 allocation between intervention and placebo arms and followed for 12 weeks. This study will enroll up to 1,700 participates in Lafayette, Louisiana. The primary outcome will number of symptomatic COVID-19 infections. Secondary endpoints included number of days healthcare workers are absent from work and rate of severe infection.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The study is a double blind placebo controlled at two hospitals in Lafayette, Louisiana aiming to enroll 1700 participants with a 1:1 randomization. The HCQ dose in 400mg twice on day 1, then 200mg twice weekly. The primary outcome variable is development of symptomatic COVID-19 infection. The secondary objectives are number of days absent from work due to symptomatic COVID-19 infection and rate of severe disease due to COVID-19 (hypoxia in setting of >50% lung involvement on chest imaging, respiratory failure, shock or end-organ damage). The study will enroll participants for four weeks with and plan to treat with hydroxychloroquine versus placebo for a total of 12 weeks.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Incidence of symptomatic COVID-19 infection in healthcare workers
Time Frame: 12 weeks

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Absenteeism from work due to COVID-19
Time Frame: 12 weeks
Number of days healthcare workers are absent from work due to symptomatic COVID-19 infection
