  Purpose

A substance called immunoglobulin E (IgE), which is naturally produced by our body, has a key role in generating asthma attacks. In patients with allergies, there is an exaggerated production of IgE in response to specific substances such as pollens. Omalizumab is a new drug that inactivates IgE. This study tested the safety and efficacy of omalizumab against asthma attacks in children with allergic asthma.

Primary Outcome Measures:
  • Rate of Clinically Significant Asthma Exacerbations Per Patient in the 24-week Fixed-dose Steroid Treatment Period [ Time Frame: Baseline to end of the fixed-dose steroid treatment period (Week 24) ] [ Designated as safety issue: No ]
    A clinically significant asthma exacerbation was defined as a worsening of asthma symptoms, as judged clinically by the investigator, requiring doubling of the baseline inhaled corticosteroid dose and/or treatment with systemic rescue corticosteroids for at least 3 days. The exacerbations rate per patient was derived using Poisson model adjusted by time at risk and the following covariates: country, exacerbation history, and dose schedule. A patient's person-days at risk was taken as the total amount of time (in days) he/she spent in the 24-week fixed-dose steroid treatment period.

  • Percentage of Participants With at Least 1 Adverse Event [ Time Frame: Baseline to end of the study (Week 68) ] [ Designated as safety issue: Yes ]
    See Adverse Events module for details.


Secondary Outcome Measures:
  • Change in Mean Nocturnal Asthma Symptom Score From Baseline to the End (Last 4 Weeks) of the 24-week Fixed-dose Steroid Treatment Period [ Time Frame: Baseline to the end (last 4 weeks) of the 24-week fixed-dose steroid treatment period ] [ Designated as safety issue: No ]
    Nocturnal asthma symptom was measured daily on a scale of 0 to 4 in response to the question "How did you sleep last night?", with 0 as the best response and 4 as the worst response. The mean of the last 4 weeks of the 24-week fixed-dose steroid treatment period was calculated; for patients who discontinued prematurely, the mean of the last 28 days before discontinuation was calculated. A negative change in mean score indicated improvement.

  • Rate of Clinically Significant Asthma Exacerbations Per Patient in the 52-week Treatment Period [ Time Frame: Baseline to end of the treatment period (Week 52) ] [ Designated as safety issue: No ]
    A clinically significant asthma exacerbation was defined as a worsening of asthma symptoms, as judged clinically by the investigator, requiring doubling of the baseline inhaled corticosteroid dose and/or treatment with systemic rescue corticosteroids for at least 3 days. The exacerbations rate per patient was derived using Poisson model adjusted by time at risk and the following covariates: country, exacerbation history, and dose schedule. A patient's person-days at risk was taken as the total amount of time (in days) he/she spent in the 52-week treatment period.

  • Change in Mean Daily Number of Puffs of Asthma Rescue Medication From Baseline to the End (Last 4 Weeks) of the 24-week Fixed-dose Steroid Treatment Period [ Time Frame: Baseline to the end (last 4 weeks) of the 24-week fixed-dose steroid treatment period ] [ Designated as safety issue: No ]
    Patients were instructed to record the number of puffs of rescue medication they took twice daily in a diary. The mean daily number of puffs during the last 4 weeks of the 24-week fixed-dose steroid treatment period was calculated; for patients who discontinued prematurely, the mean of the last 28 days before discontinuation was calculated. A negative change in mean daily number of puffs indicated reduced use of rescue medication.

  • Change in Pediatric Asthma Quality of Life Questionnaire (Standardized) [PAQLQ(S)] Scores From Baseline to the End of the 24-week Fixed-dose Steroid Treatment Period (Week 24) [ Time Frame: Baseline to the end of the 24-week fixed-dose steroid treatment period (Week 24) ] [ Designated as safety issue: No ]
    PAQLQ measures functional problems that are most troublesome to children with asthma. PAQLQ has 23 questions in 3 domains (activity limitation=5, emotional function=8, symptoms=10). Patients responded to each question on a 7-point Likert scale. Overall PAQLQ score is mean of 23 questions; each domain score is mean of questions in that domain. Minimum possible value is 1 (maximum impairment); maximum possible value is 7 (no impairment). Positive change indicated improvement. The analysis included country, baseline PAQLQ value, and dosing schedule (2-weekly/4-weekly) as factors and covariates.

Arms Assigned Interventions
Experimental: Omalizumab
Participants received omalizumab administered by subcutaneous injection every 2 or 4 weeks for a duration of 52 weeks. The omalizumab dose was based on the patient's body weight and total serum IgE level at Screening. The first 24 weeks of the treatment period was a fixed steroid phase where the steroid dose was maintained constant; in the following 28 weeks the steroid dose was adjustable, depending on the patient's condition. Following the 52-week treatment period, patients were followed up for an additional 16 weeks.
Drug: Omalizumab
The omalizumab dose administered, based on the patient's body weight and total serum IgE level at Screening, and the number of injections and injection volume was determined from the dosing tables in the protocol. Omalizumab 75 to 375 mg was administered subcutaneous (SC) every 2 or 4 weeks depending on the dose.
Drug: Fluticasone
Patients entered the study using their current formulation of any inhaled steroid (proprietary drug and device) ≥ 200 μg/day equivalent of fluticasone administered with a dry-powder inhaler.
Placebo Comparator: Placebo
Placebo was administered by subcutaneous injection every 2 or 4 weeks depending on the dosing schedule in the protocol for a total of 52 weeks. The first 24 weeks of the treatment period was a fixed steroid phase where the steroid dose was maintained constant; in the following 28 weeks the steroid dose was adjustable, depending on the patient's condition. Following the 52-week treatment period, patients were followed up for an additional 16 weeks.
Drug: Placebo
Placebo was administered subcutaneous (SC) every 2 or 4 weeks depending on the dosing schedule in the protocol.
Drug: Fluticasone
Patients entered the study using their current formulation of any inhaled steroid (proprietary drug and device) ≥ 200 μg/day equivalent of fluticasone administered with a dry-powder inhaler.

Detailed Description:

This study was designed to provide one year efficacy and safety data for subcutaneous (SC) omalizumab, compared to placebo in children (6 to < 12 years) with moderate to severe persistent asthma who have inadequate asthma control despite treatment according to National Heart, Lung and Blood Institute (NHLBI) step 3 or 4 (at least medium dose inhaled corticosteroids with or without other controller asthma medications).
