Placebo Comparator
Xolair (Immunoglobulin E (IgE) = 30-300 IU/mL)
Xolair (Immunoglobulin E (IgE) = 700-2000 IU/mL)
Xolair (Immunoglobulin E (IgE) = 301-699 IU/mL)
Placebo
Patients with screening Immunoglobulin E (IgE) levels = 30-300 IU/mL. Participants received subcutaneous injections of Xolair (Omalizumab) every 2 weeks or every 4 weeks; dosage dependent on IgE level and body weight.
Patients with screening Immunoglobulin E (IgE) levels = 700- 2000 IU/mL. Participants received subcutaneous injections of Xolair (Omalizumab) every 2 weeks; dosage dependent on IgE level and body weight.
Patients with screening Immunoglobulin E (IgE) levels = 301- 699 IU/mL. Participants received subcutaneous injections of Xolair (Omalizumab) every 2 weeks; dosage dependent on IgE level and body weight.
By subcutaneous injection of a solution with a concentration of 125 mg/mL placebo in a supine position: Patients in Xolair (Immunoglobulin E (IgE) = 30-300 IU/mL) group received doses of 150 mg to 375 mg of placebo every 2 or 4 weeks for 12 or 14 weeks. Patients in Xolair (Immunoglobulin E (IgE) = 700- 2000 IU/mL) group received doses of 450 mg, 525 mg, or 600 mg of placebo every 2 weeks for 14 weeks. Patients in Xolair (Immunoglobulin E (IgE) = 301- 699 IU/mL) group received doses of 225 mg to 375 mg of placebo every 2 weeks for 6 weeks.
