What is being measured

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

  1. Number of Asthma Episodes Culminating in Asthma Attack Over the 1-year Treatment Period

    The rate per year of asthma episodes culminating in an asthma attack for each of the 3 treatment groups. Asthma attacks were defined as respiratory symptoms requiring healthcare resource utilization (HRU), which comprised unscheduled visits to a physician or emergency department, treatment with corticosteroids (oral, rectal, or inhaled), or hospitalization. Each day during an episode, the patient's legal guardian recorded all the HRU that was required specifically for breathing problems.

    Measured: 1-year treatment period

Secondary outcomes (2)
  1. Daily Average of Wheeze and Difficulty Breathing in the 3 Days Prior to Start of an Asthma Attack Within an Asthma Episode

    Each day during an asthma episode, the patient's legal guardian was asked to rate each of the symptoms of wheeze and difficulty breathing on a 6-point scale (Scale 0 (best) to 5 (worst)). The average of the individual symptom scores on each of the 3 days prior to an asthma attack was reported. If a patient had multiple episodes during 1 year, the symptom scores were averaged across all the episodes.

    Measured: 1 Year

  2. Daily Average of the Mean Symptom Scores (Wheeze, Difficulty Breathing, Interference With Activity, and Daytime Cough) Assessed Over the 12-day Treatment Period of Asthma Episodes

    Each day during an asthma episode, the patient's legal guardian was asked to rate each of the symptoms of Wheeze, Difficulty Breathing, Interference with Activity, and Daytime Cough on a 6-point scale (Scale 0 (best) to 5 (worst)). The average of the individual symptom scores on each of the 12 days of intermittent treatment for an episode (before the first attack) was reported. If a patient had multiple episodes over 1 year, the symptom scores were averaged across all the episodes.

    Measured: 1 Year

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing montelukast sodium in people with Asthma, run by Organon and Co.

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 1 inclusion and 2 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 10 May 2024. 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 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?

Yes. Results are posted in the registry (first posted 15 Mar 2010). 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?

Number of Asthma Episodes Culminating in Asthma Attack Over the 1-year Treatment Period (time frame: 1-year treatment period). 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 NCT00337675, 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 10 May 2024.
