Preventative Omalizumab or Step-up Therapy for Severe Fall Exacerbations

Completed · Phase 4 · Has a placebo group

Conditions studied: Asthma

In brief

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.
