About this study

Official title: Proof of Concept, Multicentre, Parallel, Randomized, Double-blind Clinical Trial to Assess the Safety and Efficacy of Nitazoxanide 600 mg Compared to Placebo in the Treatment of Hospitalized Patients With COVID-19 in Moderate Condition.

This is a proof of concept study to evaluate the efficacy of nitazoxanide (600 mg BID) to treat hospitalized patients with moderate COVID-19.

Read the detailed description

This is a proof of concept study to evaluate the efficacy of nitazoxanide (600 mg BID) to treat hospitalized patients with moderate 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 for 7 days on top of standard care compared to patients who receive standard care and placebo.

Patients hospitalized with confirmed diagnosis of COVID-19 will be randomized to receive either nitazoxanide or placebo.

What is being measured

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

  1. Viral load

    PCR will be done to evaluate the change in viral load

    Measured: day 1, 4, 7, 14 and 21

Secondary outcomes (5)
  1. Evolution of acute respiratory syndrome

    Time to wean off oxygen supplementation

    Measured: 21 days

  2. Change in Clinical Condition

    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: 21 days

  3. Hospital discharge

    Time to be discharged from hospital

    Measured: 21 days

  4. Rate of mortality within 21-days

    Evaluation of change in acute respiratory syndrome

    Measured: 21 days

  5. Need of mechanical ventilation

    Evaluation of change in acute respiratory syndrome

    Measured: 21 days

Where is the study taking place?

The record lists 3 sites 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.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Viral load (time frame: day 1, 4, 7, 14 and 21). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04348409, which also lists 1 linked publication.

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 28 Oct 2022.
