Healthy volunteers
Not accepted
You may be eligible if
Adults aged \>= 18 years.
Patients with severe persistent allergic asthma with the following characteristics:
FEV1 (Forced Expiratory Volume in One Second) \<80% of predicted.
Frequent daily symptoms (\>=4 days/week on average) or nocturnal awakening (\>=1/week on average).
Multiple severe asthma exacerbations: either \>=2 severe asthma exacerbations having required an unscheduled medical intervention with systemic corticosteroid in the past year, or hospitalization (including emergency room treatment) for an asthma exacerbation in the past year.
Despite a high dose inhaled corticosteroid \>1000 mg beclomethasone dipropionate or equivalent and a inhaled long-acting B2-agonist.
With an allergy to a perennial allergen demonstrated with convincing criteria, i.e. positive prick skin test or in vitro reactivity to a perennial aeroallergen (RAST).
Total serum IgE level \>= 30 to \<=700 IU/ml and suitable serum total IgE level and weight according to Xolair dosing tablets.
You may not be if
Age \< 18 years.
Smoking history \> 20 pack years.
Patients who have had an asthma exacerbation during the 4 weeks prior to randomization
History of food or drug related severe anaphylactoid or anaphylactic reaction
Elevated serum IgE levels for reasons other than allergy (e.g. parasite infections, hyperimmunoglobulin E syndrome, Wiskott-Aldrich Syndrome or allergic bronchopulmonary aspergillosis).
Patients with active cancer, suspicion of cancer or any history of cancer.
Pregnant women.
Known hypersensitivity to omalizumab or to one of its components.
Patients already treated with omalizumab (indeed a previous treatment with omalizumab could have modified the FceRI expression).
Patients who had participated in a clinical trial in the past 3 months.
