Timeline
Interventions
Participants received active omalizumab (Xolair(R)) injections and a placebo inhaler. Each participant received omalizumab (Xolair(R)) subcutaneous injections at minimum dose of 0.016 mg/kg/IgE (immunoglobulin E) \[IU/mL\] every 2 or 4 weeks during the 4-5 months treatment period. All participants received standardized specialist asthma care.
Self-administered fluticasone (Flovent ® Diskus®) inhalers sufficient to deliver the required 200 mcg or 500 mcg daily boost of fluticasone. All participants will receive standardized specialist asthma care.
Placebo was administered subcutaneously every 2 or 4 weeks over a period of 4 to 5 months. Doses (mg) and dosing frequency were determined by serum total immunoglobulin E (IgE) level (IU/mL) and body weight (kg). Also, participants continued with their conventional asthma therapy according to the National Asthma Education and Prevention Program (NAEPP, 2007) guidelines, under the management of an asthma specialist health care provider.
Self-administered placebo fluticasone (placebo Flovent ® Diskus®) inhalers identical in dose and guidance as active fluticasone. All participants will receive standardized specialist asthma care.
