Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 12 to 120 years
  • All sexes
  • No healthy volunteers
  • Child, Adult, Older adult

Who may be able to join

  • Male or female outpatients at least 12 years of age
  • Presence of clinical signs and/or symptoms consistent with worsening or stable cold due to Enterovirus/Rhinovirus infection (one of the following is required):
  • Presence of at least two respiratory symptom domains (head, throat, nose, chest, cough) with a score of ≥2 as determined by Screening FLU-PRO OR
  • Presence of at least one respiratory symptom domain (head, throat, nose, chest, cough) with a score of ≥2 as determined by Screening FLU-PRO with pulse rate ≥90 OR
  • Presence of at least one respiratory symptom domain (head, throat, nose, chest, cough) with a score of ≥2 as determined by Screening FLU-PRO with respiratory rate ≥16
  • AND patient reported assessment that symptoms are present, the symptoms are not consistent with the subject's usual health, the symptoms interfere with daily activities, and the symptoms have worsened or remained the same relative to the previous day, as confirmed by responses to questions in the Screening FLU-PRO.
  • Onset of symptoms no more than 72 hours before enrollment in the trial. Onset of symptoms is defined as the earlier of the first time at which the subject experienced subjective fever or any respiratory symptom (head, throat, nose, chest, or cough symptoms).
  • Willing and able to provide written informed consent (including assent by legal guardian if under 18 years of age) and comply with the requirements of the protocol, including completion of the subject diary and all protocol procedures.

Who cannot join

  • Subjects who experienced a previous episode of acute upper respiratory tract infection, otitis, bronchitis or sinusitis or received antibiotics for these conditions within two weeks prior to and including study day 1.
  • Severely immunodeficient persons including:
  • Subjects with immunologic disorders or receiving immunosuppressive therapy (e.g., for organ or bone marrow transplants, immunomodulatory therapies for certain autoimmune diseases).
  • Subjects with untreated human immunodeficiency viruses (HIV) infection or treated human immunodeficiency viruses (HIV) infection with a CD4 count below 350 cells/mm3 in the last six months.

  • Subjects with active respiratory allergies or subjects expected to require anti- allergy medications during the study period for respiratory allergies.
  • Females of childbearing potential who are either pregnant or sexually active without the use of birth control. Female subjects of child-bearing potential that are sexually active must have a negative baseline pregnancy test and must agree to continue an acceptable method of birth control for the duration of the study and for 1 month post-treatment. A double barrier method, oral birth control pills administered for at least 2 monthly cycles prior to study drug administration, an Intrauterine Device (IUD), or medroxyprogesterone acetate administered intramuscularly for a minimum of one month prior to study drug administration are acceptable methods of birth control for inclusion into the study. Female subjects are considered of childbearing potential unless they are postmenopausal (absence of menstrual bleeding for 1 year - or 6 months if laboratory confirmation of hormonal status), or have had a hysterectomy, bilateral tubular ligation or bilateral oophorectomy.
  • Subjects residing in the same household with another subject participating in the study.
  • Treatment with any investigational drug or vaccine therapy within 30 days prior to screening and willing to avoid them during the course of the study.
  • Receipt of any dose of nitazoxanide (NTZ) within seven days prior to screening.
  • Known sensitivity to nitazoxanide (NTZ) or any of the excipients comprising the study medication.
  • Subjects unable to swallow oral tablets or capsules.
  • Subjects with known severe heart, lung, neurological or other systemic disease that the Investigator believes could preclude safe participation.
  • Subjects likely or expected to require hospitalization unrelated to cold during the study period.
  • Subjects who, in the judgment of the Investigator, will be unlikely to comply with the requirements of this protocol including completion of the subject diary.
  • Subjects taking medications considered to be major CYP2C8 substrates.
  • Persons with any clinical sign or symptoms suggestive of severe systemic illness with COVID-19, including the following:
  • shortness of breath at rest,
  • resting pulse ≥125 beats per minute,
  • resting respiratory rate ≥ breaths per minute, or
  • SpO2 ≤ 93% on room air at sea level.
  • Subjects known to have a diagnostic test positive for SARS-CoV-2 or influenza infection within the preceding three weeks.

What is being measured

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

  1. Time From First Dose to Sustained Response

    Time to Sustained Response is the time in days from the first dose of study medication to the first time at which the subject reports a decrease in total FLU-PRO score from the previous diary with assessment that symptoms are at least "somewhat better than yesterday", no oral temperature ≥100.4 F in the prior 24 hours, and no future increase in any of the FLU-PRO domains except within validated background levels.

    NOTE: Data collection ended at study day 21 and >25% of subjects in each treatment group had not yet achieved Sustained Response (32% in the Nitazoxanide group and 35% in the Placebo group). Therefore, it was impossible to calculate a third quartile for either group. Data presented here imputes "21" as the third quartile. No statistical analyses were performed as enrollment was terminated early. See caveats and limitations.

    Measured: 21 days

Secondary outcomes (1)
  1. Proportion of Subjects Requiring Systemic Antibiotics

    Proportion of subjects requiring systemic antibiotics for an infection secondary to Enterovirus/Rhinovirus. NOTE: No statistical analyses were performed as enrollment was terminated early. See caveats and limitations.

    Measured: 21 days

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Nitazoxanide and Vitamin Super B-Complex in people with Enterovirus and Rhinovirus, run by Romark Laboratories L.C. at 3 sites in United States.

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 8 inclusion and 23 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: stopped early, as of the sponsor's last update on 17 Oct 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites 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 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?

Yes. Results are posted in the registry (first posted 17 Oct 2024). 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?

Time From First Dose to Sustained Response (time frame: 21 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 17 Oct 2024.
