About this study

Official title: A Double-blind, Randomized, Cross-over Design Study to Compare the Lung Function Measure of Montelukast Versus Placebo in Children With Mild Persistent Asthma

This study aims to identify markers to prove rapid improvement of lung function, airway inflammation and bronchodilator response after 2-week LTRA administration.

Read the detailed description

This study is a randomized, double-blind, placebo-controlled, cross-over study with a washout period of at least one week between each study period.

After an initial screening visit, subjects entered a screening period of one to two weeks to ensure clinical stability without medication, which means absence of daily asthma symptoms. Eligible subjects were randomized into either the treatment portion of the trial, in which subjects received montelukast (4 mg or 5 mg) or matching placebo monotherapy in a randomized manner. During each treatment period, which lasted 2 weeks, the study medication was administered between 8:00 and 9:00 A.M. Short acting bronchodilator (for severe symptoms) was permitted during the study period but was withheld 24 hours prior to bronchodilator challenge test.

Inclusion criteria will be mild persistent asthma children old enough to cooperate on performing pulmonary function testing, children with no respiratory symptoms 4 weeks prior to the beginning of the study. Exclusion criteria will be the following: respiratory symptoms including cough, wheezing, dyspnea, or shortness of breath, presence of acute or chronic upper respiratory infections, anatomical nasal disorders (ex, nasal polyps, septum deviation, etc.), previous or current specific immunotherapy, use of systemic corticosteroids, or admission or visit of the emergency department during the previous 4 weeks.

What is being measured

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

  1. Baseline Lung Function of Rrs 5 With IOS Before the Bronchodilator (Pre-Rrs5)

    Pre Rrs 5: Resistance at 5Hz before the administration of bronchodilator

    Measured: up to 2 weeks

  2. Baseline Lung Function of Xrs5 With IOS Before the Bronchodilator (Pre-Xrs 5)

    Pre Xrs 5: Reactance at 5Hz before the administration of bronchodilator

    Measured: up to 2 weeks

  3. Baseline Lung Function of Rrs10 With IOS Before the Bronchodilator

    Pre Rrs10: Resistance at 10Hz before the administration of bronchodilator

    Measured: up to 2 weeks

  4. Baseline Lung Function of Xrs10 With IOS Before the Bronchodilator (Pre-Xrs10)

    Pre Xrs 10: Reactance at 10Hz before the administration of bronchodilator

    Measured: up to 2 weeks

  5. Baseline Lung Function of FEV1 Before the Bronchodilator

    baseline lung function in forced expiratory volume in 1 second before the administration of bronchodilator

    Measured: up to 2 weeks

  6. Baseline Lung Function of FEV1/FVC Before the Bronchodilator

    baseline lung function in forced expiratory volume in 1 second/forced vital capacity before the administration of bronchodilator

    Measured: up to 2 weeks

  7. Baseline Lung Function in MMEF

    Baseline lung function in maximal mid-expiratory flow before the administration of bronchodilator

    Measured: up to 2 weeks

Secondary outcomes (1)
  1. Relative Change (%) of FEV1 After the Bronchodilator

    Relative change in percentage of FEV1 after the bronchodilator, 2weeks after placebo and montelukast administration Relative change (%) in FEV1 = (((FEV1 post-bronchodilator)-(FEV1 pre-bronchodilator))/baseline FEV1) x 100

    Measured: up to 2 weeks

Questions about this trial

What is this clinical trial studying?

A study of Mild Persistent Asthma, run by CHA University.

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 3 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 12 Apr 2018. 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. 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?

Yes. Results are posted in the registry (first posted 12 Apr 2018). 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?

Baseline Lung Function of Rrs 5 With IOS Before the Bronchodilator (Pre-Rrs5) (time frame: up to 2 weeks). The study lists 7 primary outcomes in all. 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 12 Apr 2018.
