Efficacy/ Safety of Omalizumab in Patients With Seasonal Allergic Asthma and Seasonal Allergic Rhinoconjunctivitis

A Randomized, 20 Week, Double-blind, Placebo-controlled, Parallel-group, Multiple-dose, Multicenter Study to Assess the Efficacy and Safety of Omalizumab in Combination With Depigoid, Versus Depigoid Only, in Adult and Adolescent Patients With Seasonal Allergic Asthma and Comorbid Seasonal Allergic Rhinoconjunctivitis - Open-label Depigoid Monotherapy Extension Periods 2007 and 2008-

Efficacy/ safety for the combination of anti-IgE (Omalizumab) and specific immunotherapy (Depigoid) in patients with not adequately controlled seasonal allergic asthma and comorbid seasonal allergic rhinoconjunctivitis.

This was an open-label extension period of the previously randomized, multicenter, double-blind, placebo-controlled, parallel-group trial to demonstrate the benefit of pre- and co-seasonal combination therapy with anti-IgE (omalizumab) and specific immunotherapy (Depigoid) in patients with seasonal allergic asthma and co-morbid seasonal allergic rhinoconjunctivitis. During the open-label period, all patients received Depigoid monotherapy for two follow-up seasons every 4 weeks, 26 injections in total. The extension period was performed to evaluate the influence of omalizumab on the follow-up treatment with Depigoid in seasonal asthma.

This study was a follow-up to the core IGE025ADE03 study, in which patients received omalizumab treatment. In this follow-up study, no patient received omalizumab.

Inclusion Criteria:

• Patients with the diagnosis of not adequately controlled seasonal grass pollen (and/or rye pollen) and allergic asthma with concomitant seasonal allergic rhinoconjunctivitis within > 2 previous seasons
• patients with a positive RAST (>CAP2) result for grass pollen (and/or rye pollen) specific IgE at screening (Visit 1 (V1) or within the previous 12 months.
• Patients with FEV1 > 80% of the predicted normal value for the patient at screening [V1](demostrable at least 6 hours after last short acting B-2 agonist use or 12 hours after last long B-2 acting agonist use).

Exclusion Criteria:
