What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • NiclosamideDrug

    Niclosamide is a broad spectrum, host targeting antiviral that inhibits viral replication (by neutralizing endosomal pH) and increases viral clearance (by increasing the autophagic flux). The niclosamide solution is administered directly to the nasal cavity via a nasal spray.

  • PlaceboDrug

    The placebo formulation contains purified water, sodium chloride as common isotonizing agent and the FAO/WHO approved colorant FD\&C Red 40 to match the red-orange colour of the active solution. The solution is administered directly to the nasal cavity via a nasal spray.

What is being measured

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

  1. Proportion of subjects with worsened symptoms any time from Day 3 to Day 10 compared with baseline

    Worsening is assessed by the Food and Drug Administration (FDA) COVID-19 Symptom Questionnaire, assessing severity of symptoms over the past 24 hour period.

    Measured: Day 3 to Day 10

Secondary outcomes (8)
  1. Proportion of subjects with worst intensity/grade up to Day 10 and up to Day 15 in any single symptoms in the 3 domains of the FDA COVID-19 questionnaire

    Assessed by the FDA COVID-19 symptom questionnaire divided into 3 domains - Items 1 to 10, items 11 to 12 and items 13 to 14

    Measured: Day 10 and up to Day 15

  2. Proportion of subjects reporting the following number of symptoms with worst intensity/severe grade: ≥ 1 symptom, ≥ 2 symptoms, ≥ 3 symptoms, etc.

    Assessed by the FDA COVID-19 symptom questionnaire looking at the individual symptoms

    Measured: Any time point

  3. Proportion of subjects with worsened symptoms at Day 15 compared with baseline.

    Worsening is assessed by the FDA COVID-19 Symptom Questionnaire, which is a self reported questionnaire assessing severity of symptoms over the past 24 hour period.

    Measured: Day 15

  4. Change from baseline in each single symptom score

    Assessed by the FDA COVID-19 symptom questionnaire looking at the individual symptoms

    Measured: Days 10, 15 and 30

  5. Proportion of subjects who are asymptomatic on Day 10

    Assessed by the FDA COVID-19 symptom questionnaire

    Measured: Day 10

  6. Proportion of subjects requiring visits to urgent care (UC) or emergency department (ED) facilities, or hospitalization because of signs or symptoms of COVID-19

    Number of visits to urgent care (UC) or emergency department (ED) facilities, or hospitalization is assessed by a self developed questionnaire

    Measured: Day 10, 15 and 30

  7. Proportion of subjects admitted to intensive care units (ICU) and/or died

    Assessed by WHO 11-point Ordinal Scale

    Measured: At screening, Day 1, and every other day through Day 10, and again at Day 15 and Day 30

  8. Change from baseline in SARS-CoV-2 viral load at Day 5 and Day 10

    Assessed by quantitative reverse transcription polymerase chain reaction (qRT-PCR)

    Measured: Day 5 and Day 10

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Niclosamide in people with Covid19, run by UNION therapeutics at 3 sites in Germany.

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 4 inclusion and 4 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 21 Feb 2022. 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 Germany. 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?

The study was stopped early (reason given: Failure of recruiting patients). Results are not available in the source record.

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 subjects with worsened symptoms any time from Day 3 to Day 10 compared with baseline (time frame: Day 3 to Day 10). 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 21 Feb 2022.
