  • resting pulse ≥125 beats per minute
  • resting respiratory rate ≥30 breaths per minute
  • Oxygen saturation ≤ 93% on room air at sea level
  • Immunocompetent persons who have been fully vaccinated for SARS-CoV-2, defined as having received all expected vaccine doses for a 2-dose or single-dose series at least two weeks prior to onset of symptoms.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Nitazoxanide and Vitamin Super-B Complex in people with COVID-19, run by Romark Laboratories L.C..

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 16 inclusion and 17 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The record says: withdrawn, as of the sponsor's last update on 24 Sep 2024.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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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The study was withdrawn before enrolling participants, so there are no results.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

Proportion of participants progressing to severe COVID-19 or death from any cause (time frame: Day 1 through Day 28). 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 24 Sep 2024.
