Brief summary

Adults who do not have major health, kidney, gastrointestinal disease will be randomized to receive oral mitoquinone/mitoquinol mesylate (Mito-MES) versus placebo to prevent the development and progression of COVID-19 after high-risk exposure to a person with confirmed SARS-CoV-2 infection.

Detailed description

The overall goal of the study is to determine the efficacy of the treatment with mito-MES 20 mg daily versus placebo for 14 days to prevent confirmed SARS-CoV-2 infection in high-risk close contacts of confirmed COVID-19 cases. Primary measure will be confirmed COVID-19 infection based on a diagnostic test within 14 days after exposure. Secondary measures of efficacy will be symptomatic viral infection, hospitalization, respiratory failure requiring ventilatory support attributable to COVID-19 disease, mortality. The secondary objective is to determine the safety of mito-MES for 14 days as post-exposure prophylaxis against SARS-CoV-2 in healthy adults.

Masking description

The study participants and the investigators involved in the acquisition and analysis of key outcomes will be blinded to the group status of the subjects. The double-blind drugs will be labelled within the institutional investigational drug service pharmacy.

Intervention model description

Group 1: Mito-MES 20 mg daily initiated within 3 days post exposure and taken daily during the study Group 2: Placebo.
