About this study

Official title: The Protocol of Evaluation of Safety and Efficiency of Method of Exosome Inhalation in SARS-CoV-2 Associated Two-Sided Pneumonia

Coronavirus is an acute viral disease with prevailing upper respiratory tract infections caused by the RNA-containing virus of the genus Betacoronavirus of the Coronaviridae family. Most patients with severe COVID-19 develop pneumonia in the first week of the disease. As the infection progresses, the infiltration increases, and the affected areas increases. Excessive and uncontrolled immune system response with rapidly developing fatal cytokine storm plays the main role in the pathogenesis of acute respiratory distress syndrome (ARDS) due to SARS-CoV-2 infection.

According to available data, exosomes can regulate inflammation and regenerative processes due to the change in the concentration of anti-inflammatory cytokines and switch the immune cell to regenerative secretome. Inhalation of exosomes may reduce inflammation and damage to the lung tissue and stimulate the regenerative processes.

This protocol has been developed based on the literature, information about the ongoing tests NCT04276987 (A Pilot Clinical Study on Inhalation of Mesenchymal Stem Cells Exosomes Treating Severe Novel Coronavirus Pneumonia) and NCT04384445 (Organicell Flow for Patients With COVID-19), Patent No 271036826 of 2019. "A method for obtaining and concentrating microRNA-containing exosomal multi-potent mesenchymal-stromal cells for use in cosmetic and pharmaceutical products to stimulate regenerative processes and slow down aging.

Read the detailed description

COVID-19 is an infectious disease caused by the most recently discovered coronavirus. This new virus and disease were unknown before the outbreak began in Wuhan, China, in December 2019. COVID-19 is now a pandemic affecting many countries worldwide. Globally, as of 1:09 pm CEST, 27 July 2020, there have been 16 096 741 confirmed cases of COVID-19, including 646 384 deaths, reported to WHO.

The main and rapidly achievable target of SARS-CoV-2 is lung type II alveolar cells (AT2), which determines the development of diffuse alveolar damage. In the pathogenesis of ARDS due to COVID-19, the main role is played by an over-response of the immune system with rapidly developing severe life-threatening cytokine release syndrome (cytokine storm). Cytokine release syndrome threatens the emergence and progression of ARDS. The key components of the pathogenesis of ARDS also include disruption of cell cytotoxicity mechanisms, excessive activation of cytotoxic lymphocytes and macrophages with a massive release of proinflammatory cytokines (FNO-α, IL-1, IL-2, IL-6, IL-8, IL-10), granulocytic colony-stimulating factor, monocytic chemoattractive protein 1), and inflammatory markers (CRP, serum ferritin), infiltration of internal organs and tissues by activated T-lymphocytes and macrophages, resulting in a hyperinflammatory reaction. Such severe lesions can lead to death or severe lung damage, including long rehabilitation after discharge.

Experimental studies have demonstrated that mesenchymal stem cells (MSCs) may significantly reduce lung inflammation and pathological impairment resulting from different types of lung injury. Many researchers connect the anti-inflammatory effect of MSC with their secretome which includes MSC derived exosomes. It is highly likely that MSC exosomes have the same therapeutic effect on inoculation pneumonia as MSCs themselves. Moreover, exosomes show a strong effect of regenerative stimulation on different wounds so the regenerative effect can be extended on patients with COVID-19 pneumonia.

The purpose of this protocol is to explore the safety and efficiency of aerosol inhalation of the exosomes in the treatment of severe patients hospitalized with novel coronavirus pneumonia (NCP).

What is being measured

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

  1. Number of Participants With Non-serious and Serious Adverse Events During Trial

    Safety assessment such as adverse events will be registered. Adverse events will be monitored during all trial

    Measured: 30 days after clinic discharge

  2. Number of Participants With Non-serious and Serious Adverse During Inhalation Procedure

    Safety assessments such as adverse events during the inhalation procedures will be registered.

    Measured: after each inhalation during 10 days

Secondary outcomes (4)
  1. Time to Clinical Recovery (TTCR)

    Measure and compare time to clinical recovery compared to placebo. Time to clinical recovery calculated by the number of days the patient has hospitalized.

    Measured: from first inhalation until discharge from the clinic, up to 30 days

  2. SpO2 Concentration

    The concentration of SpO2 by Pulse oximetry device during procedures in the groups. The measure was done before and after each inhalation (total 4 measures per day). The intraday SpO2 data of all patients in groups was calculated as Median with Inter-Quartile Range and presented in the table by days.

    Measured: 10 days during inhalation

  3. C-reactive Protein

    Blood biochemistry C reactive protein level in serum.

    Measured: At the begining of inhalation (day 1) and on next day of last inhalation (day 11)

  4. Lactic Acid Dehydrogenase (LDH)

    Lactic Acid Dehydrogenase (LDH) level in serum

    Measured: At the beginning of inhalation (day 1) and on next day of last inhalation (day 11)

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 4 inclusion and 15 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: finished, as of the sponsor's last update on 4 Nov 2020. 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 Russia. 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?

Yes. Results are posted in the registry (first posted 4 Nov 2020). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of Participants With Non-serious and Serious Adverse Events During Trial (time frame: 30 days after clinic discharge). 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?
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 4 Nov 2020.
