What is being measured

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

  1. The Proportion of Participants Reporting Treatment-emergent Adverse Events (AEs)

    Participants were treated for 28 days with either 6 or 12 Units of SCH 39641 or placebo, and the proportion with treatment-emergent AEs were recorded. An AE is any unfavorable and unintended sign, symptom or disease temporarily associated with the use of a medicinal product, whether or not considered related to the medicinal product. Treatment-emergent AEs are new AEs that occur after participants have been randomized into the trial, or existing AEs that occurred during Screening that increase in severity after randomization.

    Measured: Up to Day 42

Secondary outcomes (5)
  1. Proportion of Participants Reporting Oral Pruritus

    Participants were treated for 28 days with either 6 or 12 Units of SCH 39641 or placebo, and the proportion with oral pruritus were reported.

    Measured: Up to Day 42

  2. Proportion of Participants Reporting Ear Pruritus

    Participants were treated for 28 days with either 6 or 12 Units of SCH 39641 or placebo, and the proportion with ear pruritus were reported.

    Measured: Up to Day 42

  3. Proportion of Participants Reporting Throat Irritation

    Participants were treated for 28 days with either 6 or 12 Units of SCH 39641 or placebo, and the proportion with throat irritation were reported.

    Measured: Up to Day 42

  4. Proportion of Participants Reporting Mouth Oedema

    Participants were treated for 28 days with either 6 or 12 Units of SCH 39641 or placebo, and the proportion with mouth oedema were reported.

    Measured: Up to Day 42

  5. Proportion of Participants Who Discontinued Due to Adverse Events.

    Participants were treated for 28 days with either 6 or 12 Units of SCH 39641 or placebo, and the proportion with AEs leading to study discontinuation were reported. An AE is any unfavorable and unintended sign, symptom or disease temporarily associated with the use of a medicinal product, whether or not considered related to the medicinal product.

    Measured: Up to Day 28

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing SCH 39641 in people with Rhinoconjunctivitis and Rhinitis, run by ALK-Abelló A/S.

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 9 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: finished, as of the sponsor's last update on 3 Mar 2017. Status can change between updates, so confirm with the study contact before making plans.

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 23 May 2014). 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?

The Proportion of Participants Reporting Treatment-emergent Adverse Events (AEs) (time frame: Up to Day 42). 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 NCT00978029, 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 3 Mar 2017.
