About this study

Official title: Mesenchymal Stem Cell Exosomes for the Treatment of COVID-19 Positive Patients With Acute Respiratory Distress Syndrome and/or Novel Coronavirus Pneumonia

Novel coronavirus pneumonia (NCP) and acute respiratory distress syndrome (ARDS) are both associated with the prevailing upper respiratory tract infections caused by the RNA-containing SARS-CoV2 virus of the genius Betacoronavirus of the Coronaviridae family. As both the viral infiltration and infection progress, the host immune system response can be one of a rapidly developing fatal cytokine storm. In the ARDS or NCP ensuing progression, the patient often succumbs to the effects of the hyper pro-inflammatory response, hence contributing to the associated increased mortality as a result of the cytokine storm and associated pathogenesis.

Read the detailed description

In December of 2019, in Wuhan, China, a novel coronavirus outbreak began. Globally this disease referred to as COVID-19, is the result of a novel SARS-CoV2 virus which predominantly targets Type II lung alveolar cells (AT2). The hyper response of the host immune system can rapidly evolve into a life-threatening cytokine-release syndrome or cytokine storm. The cytokine storm can predispose the patient to ARDS and/or NCP., or both. Left unchecked, the ARDS pathogenesis rapidly culminates in disruption of cell cytotoxicity mechanisms, excessive activation of cytotoxic lymphocytes, and a predominance of type I (M1) macrophage; resulting in the massive release of a host of proinflammatory cytokines (FNO-α, IL-1, IL-2, IL-6, IL-8, IL-10), granulocytic colony-stimulating factor, monocytic chemoattractive protein 1. The result systemically is a rise in surrogate inflammatory markers (C Reactive Protein, serum ferritin), with a corresponding infiltration of internal organs and tissues by activated macrophage, T-lymphocytes and a predominance of cellular apoptosis. The resulting hyperinflammatory pathogenic reaction may result in severe aveolar lesions leading to death, scarring, or severe lung damage, persisting well after discharge.

Experimental studies have demonstrated that mesenchymal stem cells (MSCs) and MSC-culutre media (MSC-CM) may significantly reduce the pro-inflammatory bias and associated pathologic impairment resulting. The MSC-CM, known to contain exosomes, has been shown to have an anti-inflammatory effect. Further exosomes associated with the amniotic membrane, long used in the treatment of burn and wounds, have been show to have a regenerative effect.

The purpose of this protocol is to explore the safety and efficacy of an intravenous injection of MSC derived exosomes in the treatment of severe patients (moderate to severe Berlin score) with ARDS or NCP.

What is being measured

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

  1. Measure and report the number of participants with treatment-related-adverse events as assessed by CTCAE v4.0; for patients receiving ARDOXSO™, perinatal MSC-derived exosome therapy.

    Quantify safety of ARDOXSO™, an interventional exosome therapy in COVID-19 in participants confirmed with SARS-CoV-2 infection who receive ARDOXSO™ as an intervention.

    Measured: 90 Days

  2. Tabulate and report the number of IMV days for patients receiving ARDOXSO™ perinatal MSC-derived exosome therapy.

    Quantify efficacy of ARDOXSO™, an interventional exosome therapy in COVID-19 in participants confirmed with SARS-CoV-2 infection who receive ARDOXSO™ as an intervention.

    Measured: 90 Days

Secondary outcomes (2)
  1. Analyze and report organ failure, associated with ICU mortality in participants confirmed with SARS-CoV2 infection, receiving ARDOXSO™ as an interventional exosome therapy.

    Correlate and analyze the Sequential Organ Failure Assessment (SOFA) score in participants confirmed with SARS-CoV2 infection, receiving ARDOXSO™, an interventional exosome therapy in COVID-19 patients. An increased SOFA score is predictive of increased mortality.

    Measured: 90 Days from last dose

  2. Record and analyze respiratory measures (Berlin Score/PEEP) following treatment regime.

    Berlin Score is a validated measure of Acute Respiratory Distress Syndrome diagnosis, which is common in COVID-19 patients, before and after receiving the interventional exosome therapy, ARDOXSO™.

    Measured: 90 Days from last dose

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 10 inclusion and 7 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 11 Mar 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

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

What does this combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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 Tammy C Luttrell, PhD (833-957-0079, tammy.luttrell@avemhealthcare.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Measure and report the number of participants with treatment-related-adverse events as assessed by CTCAE v4.0; for patients receiving ARDOXSO™, perinatal MSC-derived exosome therapy. (time frame: 90 Days). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04798716, which also lists 18 linked publications.

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 11 Mar 2022; AzTrials last refreshed its copy on 8 Nov 2026.
