  Purpose
This study was intended to demonstrate that patients with standard and high immunoglobulin E (IgE) levels can be protected from allergen induced broncho-constriction by Xolair

Condition Intervention Phase
Asthma Drug: Xolair Drug: Placebo Phase 4

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Triple (Participant, Care Provider, Investigator)
Primary Purpose: Treatment
Official Title: A Randomized, Double-blind, Placebo-controlled Study to Demonstrate the Efficacy of Xolair in an Allergen Bronchoprovocation Study in Asthmatic Populations Defined by Serum IgE Concentrations

Primary Outcome Measures:
  • Early Phase Allergic Response After Treatment With Study Drug in Active and Placebo Patients [ Time Frame: Week 8, Week 16 ]

    The EAR was defined as the maximum percent drop in forced expiratory volume in one second (FEV1) in the first 30 minutes after the challenge:

    EAR = 100* [ FEV1 (0) - Minimum FEV1 (10, 15, 30 min)] / FEV1 (0). For FEV1 (0), the "best post saline (Control) FEV1" was used. The EAR was analyzed using a linear (ANCOVA) model with a fixed effect for treatment groups and the EAR from the baseline challenge was used as a covariate.



Secondary Outcome Measures:
  • Late Phase Allergic Response After Treatment With Study Drug in Active and Placebo Patients [ Time Frame: Week 0, Week 8 and Week 16 ]
    Late-phase allergic response (LAR) was only determined for those patients who had an LAR >= 15% at baseline allergen bronchoprovocation testing. For Forced Expiratory Volume, FEV1 (0), the "best post saline (Control) FEV1" was used. LAR (%) = 100*[FEV1 (0) - Minimum FEV1 (3-8h)]/FEV1 (0).

Drug: Xolair
Xolair (Omalizumab) dose: 2 x 450 mg, 2 x 525 mg or 2 x 600 mg; subcutaneous injection;
Experimental: Xolair (Immunoglobulin E (IgE) = 700-2000 IU/mL)
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.
Drug: Xolair
Xolair (Omalizumab) dose: 2 x 450 mg, 2 x 525 mg or 2 x 600 mg; subcutaneous injection;
Experimental: Xolair (Immunoglobulin E (IgE) = 301-699 IU/mL)
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.
Drug: Xolair
Xolair (Omalizumab) dose: 2 x 450 mg, 2 x 525 mg or 2 x 600 mg; subcutaneous injection;
Placebo Comparator: Placebo
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.
Drug: Placebo
Matching placebo of Xolair (omalizumab), by subcutaneous injection of a solution with a concentration of 125 mg/mL in a supine position.
