Non-invasive Measures of Effects of Xolair in Asthma

Stopped early · Phase 4

Conditions studied: Asthma

In brief

The purpose of this study is to look at the effectiveness of Xolair® (omalizumab) in people with asthma taking Advair Diskus®. The study will look at the effects of Xolair® on lung function using high resolution computed tomography (HRCT) scans after asthma symptoms are induced with a special substance called methacholine. This study is only taking place at UCLA, where about 13 subjects will be enrolled. Participation requires 10-14 visits over about 26 weeks. Subjects will receive an albuterol inhaler to use as needed for immediate relief of symptoms and fluticasone 250 mcg/salmeterol 50 mcg or fluticasone 500 mcg/salmeterol 50 mcg (Advair Diskus® 250/50 or 500/50) to be taken twice daily. At certain visits, they will be given Xolair® injections followed by various assessments, including CT scans and lung function tests.

You may not qualify if…

• The use of the following medications will exclude subjects from entering the study: Oral or parenteral steroids- 6 months; Omalizumab- less than 12 months; Short and long-acting anticholinergics- Stop at time of run-in; Antileukotrienes, beta-adrenergic blocking agents, inhaled cromolyn sodium or nedocromil, macrolide antibiotics- Stop at time of run-in
• Tobacco within 1 year or >5 pack years.
• Pregnant women, lactating women, or women of childbearing age not willing to take precautions to avoid becoming pregnant during the study.
• Subjects with upper respiratory infection or receiving an influenza vaccine within 6 weeks before the study.
• Subjects with a history of allergy or adverse reaction to inhaled beta2-agonists, methacholine, salmeterol, fluticasone, epinephrine or omalizumab or related classes of drug(s).
• Subjects with clinically significant evidence of cardiovascular, central nervous system, endocrine, gastrointestinal, hematopoietic, hepatic, renal, psychiatric, respiratory (other than asthma) disease, or any other severe medical condition(s) that in the view of the investigator prohibits participation in the study
• Use of any other investigational agent in the last 30 days.
• Subjects with exacerbations during the run-in period that in the opinion of the investigator result in an unstable baseline
• Asthma totally controlled during the two weeks prior to omalizumab treatment. Total control is defined as: No days with symptom score > 1; No use of rescue albuterol; PEF > 80% predicted; No night-time awakening; No unscheduled physician or ED visits for asthma
