What participants receive

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

  • ExoFloDrug

    Patients will be randomized to one of three infusions: (1) Normal Saline 100 mL, (2) Normal saline 90 mL and ExoFlo 10 mL, which is 7x1011 EVs, and (3) Normal saline 85 mL and ExoFlo 15 mL, which is 10.5x1011 EVs. The study intervention will only be dosed on day=1

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing ExoFlo in people with COVID-19, run by Direct Biologics, LLC.

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 13 inclusion and 21 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The record says: withdrawn, as of the sponsor's last update on 13 Feb 2024.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?

The study was withdrawn before enrolling participants, so there are no results.

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?

Change in SARS-CoV-2 log viral load from baseline to Day=7 (time frame: 61 days). 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 13 Feb 2024.
