What is being measured

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

  1. Average change from baseline in nasal congestion scores over the first 4-hour observation period.

    Measured: Over the first 4-hour observation period.

Secondary outcomes (4)
  1. Average change from baseline in nasal congestion at each evaluation time point.

    Measured: Over 12 hours.

  2. Average change from baseline in total symptoms, total symptoms minus congestion, total nasal symptoms, total nasal symptoms minus congestion, total non-nasal symptoms, and individual symptoms scores.

    Measured: Over the first 4 hour and 12-hour study periods.

  3. Onset of action: defined as the first time point at which a sustained, statistically significant (P<=0.05) reduction relative to placebo in an efficacy variable (eg, nasal congestion) up to a pre-specified time point.

    Measured: Over the first 4-hours and 12-hour study periods.

  4. Average change from baseline in PNIF over the first 4-hour and 12-hour study periods and at each time point.

    Measured: Over the first 4-hour and 12-hour study periods.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing SCH 900538 and Pseudoephedrine in people with Seasonal Allergic Rhinitis, run by Merck Sharp & Dohme LLC.

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 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 2 Nov 2015. 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?

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?

Average change from baseline in nasal congestion scores over the first 4-hour observation period. (time frame: Over the first 4-hour observation period.). 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 2 Nov 2015.
