简要总结
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.
详细描述
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).

研究组 & 干预措施
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.

结局指标
主要结局
Rate of Clinically Significant Asthma Exacerbations Per Patient in the 24-week Fixed-dose Steroid Treatment Period
时间窗: Baseline to end of the fixed-dose steroid treatment period (Week 24)
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
时间窗: Baseline to end of the study (Week 68)
See Adverse Events module for details.
次要结局
- Change in Mean Nocturnal Asthma Symptom Score From Baseline to the End (Last 4 Weeks) of the 24-week Fixed-dose Steroid Treatment Period(Baseline to the end (last 4 weeks) of the 24-week fixed-dose steroid treatment period)
- Rate of Clinically Significant Asthma Exacerbations Per Patient in the 52-week Treatment Period(Baseline to end of the treatment period (Week 52))
- 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(Baseline to the end (last 4 weeks) of the 24-week fixed-dose steroid treatment period)
- 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)(Baseline to the end of the 24-week fixed-dose steroid treatment period (Week 24))
