About this study

Official title: A Phase III, Multicentre, Parallel, Randomized, Double-blind Clinical Trial to Assess the Efficacy and Safety of Nitazoxanide 600 mg Compared to Placebo in the Treatment of Hospitalized Patients With COVID-19 in Non-critical Condition

This is a pivotal phase III study to evaluate the efficacy of nitazoxanide 600 mg BID compared to placebo to treat hospitalized patients with non-critical COVID-19.

Read the detailed description

This is pivotal phase III study to evaluate the efficacy of nitazoxanide 600 mg BID compared to placebo to treat hospitalized patients with non-critical COVID-19.

The aim is to demonstrate a decrease in hospital related complications among patients who are hospitalized with moderate COVID-19 by treating them with nitazoxanide BID 600 mg for 7 days on top of standard care compared to placebo on top of standar care..

Therefore, patients hospitalized with confirmed diagnosis of COVID-19 will be randomized to receive either nitazoxanide 600 mg BID or Placebo.

What is being measured

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

  1. Need of mechanical ventilation

    Evaluation of change in acute respiratory syndrome using WHO Ordinal Scale for Clinical Improvement that measures illness severity over time (0=uninfected; ambulatory, no limitation of activities=1; ambulatory, limitation of activities=2, hospitalized no oxygen therapy=3; hospitalized oxygen by mask or nasal prongs=4; hospitalized non invasive ventilation or high-flow oxygen=5; hospitalized intubation or mechanical ventilation=6; hospitalized ventilation + additional organ support=7; death=8)

    Measured: 14 days

Secondary outcomes (5)
  1. Change in the pulmonary condition

    Evaluation of change in oximetry, respiratory rate and need for oxygen therapy

    Measured: Baseline, Day 7 and Day 14

  2. Change in Clinical Condition

    Evaluation of change in the following symptoms: cough, headache, myalgia and fever, level of consciousness and organ dysfunction

    Measured: Baseline, Day 7 and Day 14

  3. Change in tomographic pulmonary condition

    Evaluation of change in chest CT

    Measured: Baseline, Day 7

  4. Rate of mortality within 14-days

    Evaluation of change in acute respiratory syndrome

    Measured: 14 days

  5. Change in inflammatory markers

    Evaluation of change in inflammatory markers d-dimer and IL-6

    Measured: Baseine, Day 7, Day 14

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Nitazoxanide in people with covid19, run by Azidus Brasil at 1 site in Brazil.

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 11 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: status not confirmed, as of the sponsor's last update on 31 Oct 2022. 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 Brazil. 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?

Results are not available in the source record.

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

Contact Florentino de Araujo Cardoso Filho, MD, PhD (+55 19 991232882, florentino.cardoso@hospitalcare.com.br), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Need of mechanical ventilation (time frame: 14 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 31 Oct 2022.
