About this study

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.

Read the detailed description

Ascorbic acid [AA] (vitamin C) is an essential nutrient that, in addition to aiding tissue repair, also functions as an enzyme co-factor, an antioxidant, and a key component in lymphocyte development and function. Lymphocytes are responsible for adaptive immunity, the immune response following vaccination, in addition to playing a vital role in protection against viral disease progression. Both sepsis and aberrant lymphocyte activation have been associated with severe AA deficiency. We hypothesize that the administration of increasing concentrations of pharmacologic AA promotes lymphocyte activation and signaling in newly admitted, non-ventilator dependent COVID-19 patients via hydrogen peroxide generation and/or DNA de-methylation, and that this will lead to improved clinical outcomes.

This is a single-center, prospective, randomized, open-label, phase II clinical trial designed to assess the efficacy, tolerability, and safety of pharmacologic AA administration in hospitalized patients newly-diagnosed with COVID-19 who will likely not require mechanical ventilation within 24 hours of study intervention. All subjects enrolled will be pending inpatient admission or already admitted as they will require supplemental oxygen. Within 12 hours of admission to the E.D. or medical/surgical floor (rapid screens to determine eligibility must be completed within this time), patients will receive escalating pharmacologic AA over 2 hours once daily for 3 escalating doses, then continued on the highest dose for a total of 6 infusions.

Subjects will be randomized 2:1, with 66 subjects receiving AA treatments and 22 subjects receiving routine clinical care. The open-label design allows investigators to evaluate the safety and clinical progress in real-time. Any subject randomized to AA treatment who is upgraded to ICU-level care, requires high-flow O2 supplementation, or is intubated, will no longer receive AA infusions in order to maximize patient safety during this study. Given the robust safety data on the treatment, a phase II design was chosen with an interim safety analysis after 21 patients. Randomization will be stratified according to high vs. low risk of complications. Patients will be considered to be high risk if they have any of the following characteristics: age>60, hypertension, structural lung disease, cardiovascular disease, diabetes, immunocompromising conditions or meds (such as immunosuppressing meds in transplant patients).

Study groupRoleWhat they receive
TreatmentExperimentalAscorbic acid solution (Ascor®, McGuff Pharmaceuticals, Ltd.) will be added to each liter of sterile wate,r plus 1 g/L magnesium chloride to reduce burning sensation, and given parenterally over a 2-hour period. On the day of enrollment (Day 0), 0.3 g/kg will be given; Day 1 - 0.6 g/kg; Day 2 - 0.9 g/kg; Day 3 - 0.9 g/kg; Day 4 - 0.9 g/kg; Day 5 - 0.9 g/kg. After the first dose, each subsequent dose will be given 24 +/- 4 hours following the previous dose.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Clinical Improvement

    • Clinical improvement at 72 hours of treatment, defined as a 50% reduction in the highest flow rate of oxygen during the 72 hour period, a 50% reduction in the most frequent use of bronchodilators within a 12-hour window within the 72-hour period, or hospital discharge (whichever comes first).

    Measured: 72 hours

Secondary outcomes (5)
  1. Patient status upgraded to ICU level [Clinical decline]

    Subject is upgraded to ICU-level care

    Measured: 36 hours

  2. Oxygen supplementation

    Overall rate of oxygen supplementation in L/min

    Measured: up to 1 year

  3. Days with fever

    Number of days during hospitalization where a fever (>100.4°F) is reached at least once

    Measured: up to 1 year

  4. Days to discharge

    Number of days from initial treatment to hospital discharge

    Measured: up to 1 year

  5. SAEs

    Serious adverse events specific to treatment

    Measured: up to 1 year

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Ascorbic Acid in people with COVID-19, run by Thomas Jefferson University.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 5 May 2020. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Michael W Foster, M.D. (6107160962, mxf314@jefferson.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Clinical Improvement (time frame: 72 hours). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 5 May 2020.
