Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Primary Objective:

To assess the effect of hydroxychloroquine versus placebo on nasopharyngeal SARS-CoV-2 viral load in outpatient adults with COVID-19

Secondary Objectives:

* To assess the effect of hydroxychloroquine versus placebo on clinical signs and symptoms and progression of disease in outpatient adults with COVID-19
* To assess the safety and tolerability of hydroxychloroquine in outpatient adults with COVID-19

Detailed Description
