Trial summary

This is a randomized clinical trial designed to evaluate oral nitazoxanide compared to a placebo in the treatment of acute uncomplicated influenza in adults. We hypothesize that treatment with nitazoxanide will reduce the duration of symptoms in patients with confirmed influenza infection. Read more about this study

About this study

Official title: A Phase 2, Randomized, Double-Blind, Placebo-Controlled Study of Nitazoxanide in Adults With Acute Uncomplicated Influenza

This is a randomized clinical trial designed to evaluate oral nitazoxanide compared to a placebo in the treatment of acute uncomplicated influenza in adults. We hypothesize that treatment with nitazoxanide will reduce the duration of symptoms in patients with confirmed influenza infection. Secondarily, we hypothesize that treatment with nitazoxanide will reduce the complications of influenza, severity of symptoms, time lost from work, time to return to normal daily activities, and viral shedding.

Read the detailed description

The study is conducted at approximately 25 sites in the United States. Subjects selected based on symptoms will be randomized to receive oral nitazoxanide or placebo twice daily for 5 days. Subjects will be monitored by daily by telephone or home visit to monitor symptoms and complications of influenza for safety and will be referred for medical care as required. Subjects will complete a diary twice daily to record the presence and severity of symptoms, ability to perform normal daily activities and time lost from work. Complications of influenza (including sinusitis, otitis, bronchitis, pneumonia, central nervous system disease) and other adverse events will be reported. Nasopharyngeal swabs will be collected at Baseline (Day 0) and Day 7 for all patients and on Days 1 through 4 for a subset of patients to test for influenza A (including novel H1N1), influenza B and 17 other respiratory viruses by RT-PCR and culture and to evaluate quantitative viral shedding. The primary analysis will be for patients with confirmed influenza, and secondary analyses will be conducted for subjects with any respiratory virus and for all treated subjects.

What is being measured

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

  1. Time to Resolution of All Clinical Symptoms of Influenza (Subjects With Confirmed Influenza Infection)

    Measured: Up to 28 days

Secondary outcomes (8)
  1. Time to Resolution of All Clinical Symptoms of Influenza (Subjects Infected With Any Respiratory Virus)

    Measured: Up to 28 days

  2. Time to Resolution of All Clinical Symptoms of Influenza (All Treated Subjects)

    Measured: Up to 28 days

  3. Time to Return to Normal Daily Activity (Subjects With Confirmed Influenza)

    Measured: Up to 28 days

  4. Overall Severity of Disease Score

    Subjects recorded a severity score for 10 flu symptoms on a 0-3 scale BID for 7-14 days.The severity score for each symptom was multiplied by the number of hours scored at that severity for the entire time the subject maintained a diary (a sneezing score of 1 for 12 hours and 0 for 10 hours =1*12 + 0*10=12). This is symptom severity score*hours.Symptom severity score*hours for each of the symptoms were added for an overall symptom severity score*hours (if symptom severity score*hours for 10 symptoms were 12, 10, 9, 8, 7, 10, 10, 10, 5, 5, overall symptom severity score*hours=86).Overall symptom severity score*hours were divided by the number of hours that the subject kept a diary for a standardized continuous measure of severity of the course of illness (if overall symptom severity score*hours=86 and the subject maintained a diary for 100 hours Overall Severity of Disease Score=0.86). Overall Severity of Disease Score can range 0-30 with higher scores indicating more severe symptoms.

    Measured: Up to 14 days

  5. Time Lost From Work (Subjects With Confirmed Influenza)

    Measured: Up to 28 days

  6. Complications of Influenza Including Secondary Illnesses, Antibiotic Use and Hospitalizations (Subjects With Confirmed Influenza)

    Measured: Up to 28 days

  7. Time to Cessation of Viral Shedding (Subjects With Confirmed Influenza)

    Measured: 28 days

  8. Change in Influenza Virus Titer Assessed by Quantitative RT-PCR (Subjects With Confirmed Influenza)

    Measured: 4 days

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Nitazoxanide in people with Influenza, run by Romark Laboratories L.C. at 1 site 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 5 inclusion and 12 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 5 Apr 2018. 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 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 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 8 Aug 2017). 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 to Resolution of All Clinical Symptoms of Influenza (Subjects With Confirmed Influenza Infection) (time frame: Up to 28 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 5 Apr 2018.
