Brief Summary:

This is a randomized, double-blind, placebo-controlled study. The aim of the study is to assess the safety and clinical efficacy of low-dose naltrexone in reducing the proportion of higher risk patients who progress from mild COVID-19 to a more severe disease category.

Male and female participants with a confirmed positive SARS-CoV-2 diagnostic test at screening, who are symptomatic with mild COVID-19 (as measured by WHO clinical progression scale, WHOb 2020) and are at high risk for COVID-19 progression will be enrolled. High risk is based on presence of one or more criteria which could include age ≥65 years, increased BMI ≥33 kg/m2, or the presence of certain comorbidities (refer to Section 4 for complete eligibility criteria).
