Investigation to Identify Predictors of Response to a Treatment With Montelukast - Full Text View

Sponsor:	Marien Hospital Wesel
Collaborator:	Merck
Information provided by:	Marien Hospital Wesel
ClinicalTrials.gov Identifier:	NCT00721240

Purpose

The main aim of the study is to develop a method that allows responders to be distinguished from non-responders before long-term treatment is initiated. Subsidiary aims are to record changes in pulmonary functional parameters, NO concentrations and peak flow variability, the use of beta2 sympathomimetics and the asthma symptom score.

Primary Outcome Measures:

Patients who show a bronchospasmolytic effect in their functional pulmonary test (FEV1 increased by at least 5%) within four hours of taking montelukast. [ Time Frame: 14 days after run in ] [ Designated as safety issue: No ]

Secondary Outcome Measures:

symptom score, PEAK-Flow, rescue medication, exhaled NO [ Time Frame: 2 weeks after run in and 14 weeks after run in ] [ Designated as safety issue: No ]

Estimated Enrollment:	50
Study Start Date:	February 2006
Study Completion Date:	June 2009
Primary Completion Date:	December 2008 (Final data collection date for primary outcome measure)

Arms	Assigned Interventions
Experimental: single-arm This investigation is a single-center, two-phase, single-arm study. In order to detect a potential placebo effect, the treatment phase will be preceded by a single-blinded two-week placebo run-in phase, followed by a 12 week open-label treatment phase.	Drug: montelukast 5mg montelukast once daily for 12 weeks Other Name: Singulair ; MK-476

Exclusion Criteria:

Patients who were treated with systemic steroids within the previous 30 days
Patients using one of the following asthma medications:
- Systemic steroids
- Nedocromil, DNCG
- Theophylline
- Ketotifen
- Systemic or long-acting beta2 sympathomimetics
Patients who have experienced one of the following events within the previous 30 days:
- A change in asthma medication

- Hospitalization due to bronchial asthma or any other respiratory condition
Patients who are currently participating in another clinical trial or have done so within the previous 30 days.
Patients known or expected to react hypersensitively to components of the investigational medication
Patients receiving Phenobarbital, Phenytoin, Rifampicin (medications that are metabolized by Cytochrom P450
