Completed

• Conditions: Covid19; SARS-CoV Infection
• Interventions: Drug: Fisetin; Drug: Placebo

• Registration Number: NCT04537299
• Lead Sponsor: Mayo Clinic

Brief Summary

The purpose of this study is to test whether Fisetin, a senolytic drug, can assist in preventing an increase in the disease's progression and alleviate complications of coronavirus due to an excessive inflammatory reaction.

Detailed Description

This study is a pilot, randomized, placebo-controlled, single-center study of Fisetin in elderly nursing home participants with non-, mildly-, or moderately-symptomatic and confirmed SARS-CoV-2 infection.
