Clinical Trials


1 Efficacy of Hydroxychloroquine for Post-exposure Prophylaxis (PEP) to Prevent Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) Infection Among Adults Exposed to Coronavirus Disease (COVID-19): a Blinded, Randomized Study

This is a clinical study for the prevention of SARS-CoV-2 infection in adults exposed to the virus. This study will enroll up to 2000 asymptomatic men and women 18 to 80 years of age (inclusive) who are close contacts of persons with laboratory confirmed SARS-CoV-2 or clinically suspected COVID-19. Eligible participants will be enrolled and randomized to receive the intervention or placebo at the level of the household (all eligible participants in one household will receive the same intervention).

2 Coronavirus Disease 2019- Using Ascorbic Acid and Zinc Supplementation (COVIDAtoZ) Research Study A Randomized, Open Label Single Center Study

The purpose of this study is to examine the impact of ascorbic acid (vitamin c) and zinc gluconate in reducing duration of symptoms in patients diagnosed with coronavirus disease 2019 (COVID-19). Patients above the age of 18 who present to the Cleveland Clinic outpatient testing and receive a positive test for COVID-19 will be invited to participate.

3 Pharmacologic Ascorbic Acid as an Activator of Lymphocyte Signaling for COVID-19 Treatment

There are currently no approved therapies for patients with coronavirus disease (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Infusion of ascorbic acid (vitamin C) has been shown to increase activity of lymphocytes, which are a crucial component of the body's defense against viral disease progression and adaptive immunity. Ascorbic acid infusion has been shown to be a safe treatment for patients suffering from sepsis and certain types of cancer. This study is designed to evaluate the safety and efficacy of ascorbic acid in the form of sequential I.V. infusions (Ascor®) for patients with suspected COVID-19 who are unlikely to require mechanical ventilation within 24 hours of study intervention.
