Clinical Trial Summary

This is a prospective, multi-site study designed to evaluate whether the use of hydroxychloroquine in healthcare workers (HCW), Nursing Home Workers (NHW), first responders (FR), and Detroit Department of Transportation bus drivers (DDOT) in SE, Michigan, can prevent the acquisition, symptoms and clinical COVID-19 infection The primary objective of this study is to determine whether the use of daily or weekly oral hydroxychloroquine (HCQ) therapy will prevent SARS-CoV-2 infection and COVID-19 viremia and clinical COVID-19 infection healthcare workers (HCW) and first responders (FR) (EMS, Fire, Police, bus drivers) in Southeast Michigan. Preventing COVID-19 transmission to HCW, FR, and Detroit Department of Transportation (DDOT) bus drivers is a critical step in preserving the health care and first responder force, the prevention of COVID-19 transmission in health care facilities, with the potential to preserve thousands of lives in addition to sustaining health care systems and civil services both nationally and globally. If efficacious, further studies on the use of hydroxychloroquine to prevent COVID-19 in the general population could be undertaken, with a potential impact on hundreds of thousands of lives.


Clinical Trial Description

The study will randomize a total of 3,000 HCW, NHW, FR and DDOT bus drivers within Henry Ford Hospital System, the Detroit COVID Consortium in Southeast, Michigan. The participants will be randomized in a 1:1:1 blinded comparison of daily HCQ, weekly HCQ, or placebo. A fourth non-randomized comparator group of HCW, NHW, DDOT bus drivers, and FR who are currently on standard HCQ therapy will be recruited to assess the impact of weightbased daily dosing of HCQ as compared to the randomized arms. Eligible participants who are asymptomatic for pre-specified signs and symptoms suggestive of COVID-19 infection will have a whole blood specimen obtained at study entry. Participants will be provided with weekly dosing of hydroxychloroquine (HCQ) 400mg po q weekly, daily dosing of HCQ 200mg po q daily following a loading dose of 400mg day 1, or placebo. Participants will receive monitoring at each study week visit to assess for the development of COVID-19 related symptoms, COVID-19 clinical disease, and medication side effects. At week 8 or if diagnosed positive, participants will provide additional samples of whole blood and complete the final study questionnaire. Data including demographic, clinical results, work duties, location of main work area and possible exposures in the community will be collected through questionnaires and EMR review. Disease-specific, immunologic, and other serologic marker data will be obtained from stored samples. ;
