OBOE is a prospective, pilot, parallel group RCT with the overall aim of examining the effect of a single dose of anti-IgE (omalizumab) vs. placebo administered at the onset of URIs in the fall season among highly exacerbation-prone, urban, and atopic youth aged 6-17 years with persistent asthma. OBOE will recruit and randomize participants over 3 years (3 annual cohorts of participants). Recruitment for each of the yearly cohorts of OBOE will begin in February. Each cohort will be followed for a 2-6-month run-in period with the objective to gain control of each participant's asthma and to stabilize the required controller medication step level. Participants will receive routine asthma care every 1-2 months (a total of 2-4 times) during run-in using a previously described algorithm developed by the Inner-city Asthma Consortium and successfully employed in the PROSE study. The primary outcome is the change in the amount of nasal IFN-α recovered by nasal fluid absorption between two time points, within 72 hours of onset of a URI as defined by onset of (or substantial worsening of) rhinorrhea, nasal congestion or sneezing (single or multiple symptoms) and 3-6 days after study drug injection.
Inclusion Criteria at Study Entry: Participants must meet the following: 1. Parent or guardian must be able to understand and provide informed consent in English and participants ≥7 must be able to provide assent 2. 6-17 years, inclusive at time of screening 3. Physician-diagnosed persistent asthma 4. ≥1 exacerbation of asthma requiring systemic corticosteroids in the 6-month period before the planned start of the participant's upcoming school year or ≥2 exacerbations of asthma requiring systemic corticosteroids in the 12-month period before the planned start of the participant's upcoming sc…
Omalizumab dose for each specific participant is based on that participant's weight and total IgE level. Omalizumab is provided by the manufacturer in two strengths: • For Injection: 75 mg/0.5 mL and 150 mg/mL solution in a single-dose prefilled syringe
Matching placebo for omalizumab will be provided in 0.5 mL and 1 mL solution for injection in pre-filled syringes.
