About this study

Official title: Clinical Study for Subjects With Coronavirus 2019 (COVID-19) Using Multiple Dose Intravenous Infusions of Allogeneic Adipose Tissue-Derived Mesenchymal Stem Cells (AdMSCs)

This is an interventional new drug clinical trial for a Phase 2 randomized, double-blind, and placebo control study using intravenous injection of allogeneic adipose stem cells (Celltex AdMSCs) for subjects with severe COVID-19.

Being tested
Allogeneic adipose-derived stem cells
Medical subject headings
Coronavirus Infections, COVID-19

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Allogeneic adipose-derived stem cellsBiological

    Also called Celltex-AdMSCs

    Culture expanded mesenchymal stem cells isolated from a patient's own abdominal fat tissue

Study groups in NCT05017298
Study groupRoleWhat they receive
Study GroupExperimentalEach subject receives three separate doses of 200 million allogeneic adipose-derived mesenchymal stem cells via intravenously infusion on days 0, 3, and 6 with a total of 600 million AdMSCs during 7 days in addition to their standard of care.
Receives: Biological: Allogeneic adipose-derived stem cells
Control GroupPlacebo comparatorThe control group will receive placebo infusion on day 0, 3 and 6 along with standard of care.
Receives: Biological: Allogeneic adipose-derived stem cells

What is being measured

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

  1. Safety of AdMSC injection will be evaluated by assessment of the frequency and nature of adverse events occurring during the study based on the rate of all AdMSC-associated adverse events (AEs) in all subjects.

    Incidence of treatment-related adverse events and severe adverse events during the study period

    Measured: 6 months

  2. Safety for AdMSCs based upon incidence of all AEs

    Grouped by Medical Dictionary for Regulatory Activities (MedDRA)

    Measured: 6 months

  3. Compare the mortality rate

    AdMSC treating group vs. control group

    Measured: 6 months

Secondary outcomes (9)
  1. Recognized immune measurements evaluating patients' symptom changes and overall function

    To evaluate change of sequential organ failure assessment (SOFA) score as compare to the baseline

    Measured: 6 months

  2. Organ functional tests including blood specific enzymes and proteins

    To evaluate the efficacy of allogeneic AdMSCs for COVID-19

    Measured: 6 months

  3. Duration (days) of weaning from mechanical ventilation

    Compared to control group

    Measured: 6 months

  4. Duration (days) of ICU monitoring

    Compared to control group

    Measured: 6 months

  5. Duration (days) of vasoactive agent's usage

    Compared to control group

    Measured: 6 months

  6. Duration of hospitalization (days)

    Compared to control group

    Measured: 6 months

  7. Proportions of SARS-CoV-2 RT-PCR change to negative from respiratory tract specimens (oropharyngeal swabs) using CDC standard method

    Compared to control group

    Measured: 6 months

  8. Proportions of quantifying viral RNA in stool change to negative in final follow-up using CDC standard method

    Compared to control group

    Measured: 6 months

  9. Proportions of blood SARS-CoV-2 antibodies IgM/IgG show positive

    Compared to control group

    Measured: 6 months

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Allogeneic adipose-derived stem cells in people with Corona Virus Infection and Covid19, run by Celltex Therapeutics Corporation.

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 6 inclusion and 20 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: opening soon, as of the sponsor's last update on 7 Feb 2024. 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. 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 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?

This study is still under way. Results are not available in the source record yet.

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

Contact Jane Young, Ph.D. (7135901000, jyoung@celltexbank.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Safety of AdMSC injection will be evaluated by assessment of the frequency and nature of adverse events occurring during the study based on the rate of all AdMSC-associated adverse events (AEs) in all subjects. (time frame: 6 months). The study lists 3 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 7 Feb 2024.
