Clinical Trial Summary

This is a clinical study for the prevention of SARS-CoV-2 infection in adults exposed to the virus. This study will enroll up to 2000 asymptomatic men and women 18 to 80 years of age (inclusive) who are close contacts of persons with laboratory confirmed SARS-CoV-2 or clinically suspected COVID-19. Eligible participants will be enrolled and randomized to receive the intervention or placebo at the level of the household (all eligible participants in one household will receive the same intervention).

Description:

This is a randomized, multi-center, placebo-equivalent (ascorbic acid) controlled, blinded study of Hydroxychloroquine (HCQ) post-exposure prophylaxis (PEP) for the prevention of SARS-CoV-2 infection in adults exposed to the virus.The overarching goal of this study is to assess the effectiveness of HCQ PEP on the incidence of SARS-CoV-2 detection by polymerase chain reaction (PCR) to inform public health control strategies.This study will enroll up to 2000 asymptomatic men and women 18 to 80 years of age (inclusive) at baseline who are close contacts of persons with PCR-confirmed SARS-CoV-2 or clinically suspected COVID-19 and a pending SARS-CoV-2 PCR test. Eligible participants will be enrolled and randomized 1:1 to HCQ or ascorbic acid at the level of the household (all eligible participants in one household will receive the same intervention). Participants will be counseled about the preliminary in vitro data on HCQ activity against SARS CoV-2 and equipoise regarding efficacy in humans.The duration of study participation will be approximately 28 days.

• Concomitant use of digoxin, cyclosporin, cimetidine, or tamoxifen
• Known liver disease
• Known long QT syndrome
• Use of any investigational or non-registered drug or vaccine within 30 days preceding the first dose of the study drugs, or planned use during the study period
