E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To describe the percentage of patients with asthma and allergic rhinitis
who will achieve control of their asthma symptoms after 8 weeks of
treatment with montelukast used either in combination with inhaled
corticosteroid (ICS) or with inhaled corticosteroid/long-acting beta 2-
agonist (ICS/LABA) therapy. |
|
E.2.2 | Secondary objectives of the trial |
To evaluate the effectiveness of montelukast therapy used in
combination with ICS or ICS/LABA therapy in improving the
symptoms of asthma.
To describe the change in quality of life with respect to allergic
rhinitis for patients using montelukast therapy in combination with
ICS or ICS/LABA therapy.
To describe patient and physician satisfaction with montelukast
therapy with respect to their asthma when used in combination with
ICS or ICS/LABA therapy.
To describe patient global allergic rhinitis symptoms assessment.
To describe the percentage of asthma patients, within the survey study
sample, diagnosed with both asthma and allergic rhinitis. |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
Patients are 2> 15 years old (in the Province of Quebec, patients are 2: >18 years-old).
Patient is diagnosed with asthma for at least 6 months.
Patient has signed the Informed Consent before completing the survey.
Patient is diagnosed with asthma for at least 6 months
Patient is diagnosed with allergic rhinitis for at least one year.
Patient's forced ,expiratory volume in one second (FEV1) or Peak expiratory flow is > 80% of predicted value on the day of visit 1.
Patient is uncontrolled as per Canadian Asthma Consensus Guidelines.
Patient is a user of ICS or ICS/LABA at any dosage. The dosage of ICS or ICS/LABA must have been stable for the past 30 days. A maximum of 4 patients on ICS/LABA per block of 8 will be allowed in the study.
|
|
E.4 | Principal exclusion criteria |
Patient is well controlled with current controller therapy.
Patient is already on montelukast sodium.
Patient has rhinitis medicamentosa or non allergic rhinitis.
Patient has evidence of significant nasal obstruction due to structural causes (e.g. markedly deviated nasal septum) that significantly interferes with nasal airflow as determined by the investigator.
Patient is on a long-acting beta 2-agonist (LABA) alone, i.e. formoterol (Oxeze), salmeterol (Serevent).
Patient is currently using an antibiotic for respiratory tract infection or has been treated with an antibiotic within 30 days of Visit 1 for respiratory tract infection (Initiation of antibiotic treatment will be allowed during the study).
Patient has a history of Chronic Obstructive Pulmonary Disease (COPD).
Patient has a history of cystic fibrosis, immune deficiency requiring specific therapy or any other diseases that could influence the evolution of asthma.
Patient with hypersensitivity to any component of montelukast sodium 10 mg tablets.
Patient has participated in an investigational drug trial in the last 30 days (prior to Visit 1).

E.5 End points |
E.5.1 | Primary end point(s) |
The primary efficacy endpoint is the percentage of patients whose asthma symptoms will be controlled after 8 weeks of montelukast treatment used in combination with ICS or ICS/LABA therapy. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
|
E.5.2 | Secondary end point(s) |
The proportion of patients that achieve control of asthma symptoms at 8-weeks as measured by the Asthma Control Questionnaire score (score ≤0.75 indicated controlled symptoms).
The absolute and percent change in asthma symptom severity as measured with the Asthma Control Questionnaire score between baseline and 8 weeks. A decrease of ≥0.5 in ACQ score was considered clinically significant.
The absolute and percent change in quality of life related to allergic rhinitis as measured with the overall Mini Rhinoconjunctivitis Quality of Life Questionnaire (MiniRQLQ) score condition between baseline and 8 weeks. An average change in overall score of ≥ 0.7 was considered clinically significant.
The proportion of patients satisfied and the proportion of patients for whom the treating physicians were satisfied with treatment. Satisfaction with treatment was defined as a report of being “very satisfied” or “satisfied”, while dissatisfaction was defined as a report of being “very dissatisfied”, “dissatisfied” or “neither satisfied nor dissatisfied”.
Description of patient global allergic rhinitis symptoms assessment.
The proportion of patients diagnosed with both asthma and allergic rhinitis.
