University of Minnesota·interventional·Posted Aug 12, 2020·Updated Apr 24, 2026

In Brief

A Phase 3 clinical trial evaluating Metformin, Placebo, and 2 other interventions for Covid19 and SARS-CoV Infection. Completed, enrolled 1,323 participants across 7 sites.

Detailed Summary

1. The purpose of this trial is to conduct a 2x3 factorial randomized trials, which efficiently allows the parallel conduct of three randomized trials to understand whether metformin, ivermectin, or fluvoxamine, is superior to placebo for preventing Covid-19 disease progression in non-hospitalized adults with SARS- CoV-2 infection. 2. To understand if the active treatment arms are superior to placebo in improving viral load, serologic markers associated with Covid-19, and gut microbiome in non-hospitalized adults with SARS-CoV-2 infection. 3. To understand if any of the active treatment arms prevent long-covid syndrome, PASC (post-acute sequelae of SARS-CoV-2 infection).
