Reporting Groups
  Description
Omalizumab 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.
Inhaled Corticosteroid Boost Therapy (ICS) Participants in the Inhaled Corticosteroid (ICS) boost arm received active ICS and placebo injections of omalizumab (Xolair(R)). Self-administered fluticasone (Flovent (R) Diskus) inhalers sufficient to deliver the required 200 mcg or 500 mcg daily boost of fluticasone were used. All participants received standardized specialist asthma care.
Placebo Participants in the placebo group received placebo injection and placebo inhaler. All participants received standardized specialist asthma care.
