Overview
Brief Summary
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.
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.
