Main objective of the trial |
The Mean Change From Baseline to Week 20 in the Overall Asthma Quality of Life Questionnaire (AQLQ)
|
||
Protection of trial subjects |
Subjects were advised that between visits they could take rescue medication using inhaled salbutamol or terbuline for symptoms of intercurrent bronchospasm. The number of puffs taken during each 24 hours had to be recorded in the subject diary.
If reversibility was going to be assessed, subjects could NOT use their rescue medication within 6 hours of the spirometry, unless severe intercurrent bronchospasm was developed.

Arm description |
Omalizumab was administered subcutaneously every 2 or 4 weeks over a period of 20 weeks to provide a dose of at least 0.016 mg/kg per UI/ml of immunoglobulin E (IgE). Doses (mg) and dosing frequency were determined by serum total IgE level (IU/mL) and body weight (kg). Also, participants continued using their current formulation of inhaled corticosteroid (ICS) and long-acting beta 2-adrenergic agonist (LABA). Home use of nebulized beta 2-agonist was allowed for the treatment of symptoms of intercurrent bronchospasm or during an asthma exacerbation if this treatment regimen was already established prior to screening visit. | |||||||||||||||||||||||||||||||||

End point description |
The AQLQ was administered to all patients at Baseline, Week 12 and Week 20. The 32 questions in the AQLQ were divided into four domains; activity limitations, symptoms, emotional function, and environmental stimuli. Individual questions are equally weighted. The overall AQLQ score is the mean of the responses to each of the 32 questions, and ranges from 1 to 7. A score 7.0 indicates that the patient has no impairments due to asthma and a score of 1.0 indicates severe impairment.

The Mean Change From Baseline to the End of Study in AQLQ Domain Score | ||||||||||||||||||||||||
End point description |
AQLQ was administered to all patients at Baseline, Week 12 and Week 20, and prior to any clinic visit evaluation and drug administration.
The 32 questions in the AQLQ were divided into four domains: activity limitations, symptoms, emotional function, and environmental stimuli. AQLQ domain scores were calculated by adding the responses to each of the questions in the domain and dividing by the number of questions in the domain. Each domain score was between 1 and 7. Score 7.0 meant that the patient had no impairments due to asthma and score 1.0 indicated severe impairment.

Number of Asthma Exacerbation Episodes Per Participant | |||||||||||||||||||||||||||
End point description |
For the purpose of evaluating efficacy, a clinically significant asthma exacerbation was defined as a worsening of asthma symptoms as judged clinically by the investigator, requiring doubling the baseline ICS dose for at least 3 days and/or treatment with rescue systemic (oral or IV) corticosteroids. The initiation of the above corticosteroid regimens marked the start of an asthma exacerbation episode and cessation of the additional corticosteroid regimens marked the end of an exacerbation episode.
