Randomized Proof-of-Concept Trial to Evaluate the Safety and Explore the Effectiveness of Resveratrol, a Plant Polyphenol, for COVID-19

February 22, 2023 updated by: Marvin McCreary, MD

Randomized Double-Blind Placebo-Controlled Proof-of-Concept Trial of Resveratrol, a Plant Polyphenol, for the Outpatient Treatment of Mild Coronavirus Disease (COVID-19)

Resveratrol is a plant polyphenol (that is sold commercially as a supplement) that might help fight coronavirus as well as help protect the body from the effects of disease (COVID-19) caused by the infection. In this proof-of-concept pilot study we will compare the effects of resveratrol to placebo to assess the safety of the resveratrol and explore effectiveness.

Detailed Description

This randomized placebo-controlled trial is for the outpatient treatment of (Coronavirus Disease 2019) COVID-19. The purpose of this trial is to evaluate the safety and explore the effectiveness of resveratrol, a plant polyphenol, being re-purposed for patients with early COVID-19. Published in vitro data supports that this polyphenol inhibits coronavirus replication while separately published in silico (computer molecular docking analysis) reports have identified specific molecular targets of resveratrol against (Severe Acute Respiratory Syndrome - Coronavirus 2) SARS-CoV-2. Animal studies also demonstrate that resveratrol is effective at preventing lung injury and death in certain animal models of viral infections. Furthermore, the products long history as an anti-inflammatory might prevent the cytokine storm that is associated with worse outcomes in COVID-19.

200 subjects, 45 and older, (100 receiving the plant polyphenol, 100 receiving placebo) will be enrolled in study to compare whether taking resveratrol will reduce the rate of hospitalization. Subjects will take capsules 4 times a day for a minimum of 7 days (up to 15 days depending on duration of symptoms) plus both groups will receive Vitamin D3 100,000 IU to augment the effects of resveratrol. Resveratrol will be given as 1gm 4 times per day. Placebo tablets will contain brown rice flour in visually identical capsules. The primary outcome measure for this trial is reduction in hospitalization at 21 days from enrollment.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
