1700This 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.
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.
Hydroxychloroquine loading 400mg (2 capsules) twice 12 hours apart followed by 200mg (1 capsule) twice weekly
Loading dose of two placebo capsules twice 12 hours apart followed by 1 capsule twice weekly
Hydroxychloroquine loading dose will be given as 400mg for two doses 12 hours apart. This will then be followed by maintenance dosing of 200mg twice weekly for the remainder of the trial.
An identical placebo will be administered on an identical dosing interval and frequency.
