Official title
Non-Invasive Measures of Distal Lung Disease in Asthmatics Before and After Treatment With Omalizumab
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
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.
