Occurrence of one or more asthma exacerbations [ Time Frame: 4-5 months ] [ Designated as safety issue: Yes ]
Asthma exacerbation defined as a prescription of a course of systemic steroids by a clinician or initiation of a course of systemic steroids by a participant or a hospitalization during the fall outcome period (90 day period beginning on the first day of the participant's school year) to prevent a serious asthma outcome. If a participant initiates and completes a course of systemic steroids without clinician involvement, this course will be counted only if it meets the following minimum dosage: prednisone, prednisolone, or methylprednisolone at ≥ 20mg per day for 3 of any 5 consecutive days; or dexamethasone at ≥ 10mg per day for ≥ 1 day.
Occurrence of a severe asthma exacerbation requiring systemic corticosteroid therapy or hospitalization during the fall season [ Time Frame: 4-5 months ] [ Designated as safety issue: Yes ]

Preventative Omalizumab or Step-up Therapy for Severe Fall Exacerbations
Preventative Omalizumab or Step-up Therapy for Severe Fall Exacerbations (ICAC-20)

While the increase in the prevalence of asthma has abated, levels of asthma morbidity and mortality remain near record highs. An asthma exacerbation is a major factor contributing to morbidity, and even mortality in patients with asthma. Although current approaches to treatment have reduced these risks, asthma exacerbations are major problems for inner-city patients and their families, and prevention of these events continues to be a significant challenge. In children with asthma, there are predictable seasonal epidemics of exacerbations, especially during the fall season, otherwise known as the "September epidemic." The purpose of this trial is to compare the efficacy of 4 to 5 months of three treatments ― omalizumab, corticosteroid therapy boost, and placebo ― in reducing fall exacerbations in inner-city children and adolescents with allergic persistent asthma when initiated approximately 4 -6 weeks prior to the start of the first day of each participant's school year.

    • Biological: Placebo fluticasone
  • Experimental: Inhaled corticosteroid boost therapy (ICS)
    Participants in the Inhaled Corticosteroid (ICS) boost arm will receive active ICS and placebo injections of omalizumab (Xolair®). Self-administered fluticasone (Flovent ® Diskus) inhalers sufficient to deliver the required 200 mcg or 500 mcg daily boost of fluticasone will used. All participants will receive standardized specialist asthma care.
    • Drug: Fluticasone
    • Biological: Placebo omalizumab
  • Placebo Comparator: Placebo
    The placebo group will receive placebo injection and placebo inhaler. All participants will receive standardized specialist asthma care.
