A 26-week, Randomized, Double-blind, Parallel-group, Placebo-controlled,Multi-center Study to Evaluate the Effect of Omalizumab on Improving the Tolerability of Specific Immunotherapy in Patients With at Least Moderate Persistent Allergic Asthma Inadequately Controlled With Inhaled Corticosteroids
In Brief
A Phase 4 clinical trial evaluating Placebo, Omalizumab, and 1 other intervention for Allergic Asthma. Completed, enrolled 275 participants across 1 site.
Detailed Summary
This study is designed to investigate the use of omalizumab as a pretreatment for patients with persistent allergic asthma who are candidates for allergen immunotherapy (ie, allergy shots) and will test the hypothesis that omalizumab may reduce the rate of systemic reactions to immunotherapy in patients with persistent allergic asthma.

Interventions
Doses of placebo were administered subcutaneously every 2 to 4 weeks according to the US product label, depending on the patient's body weight and baseline serum IgE.
Doses of omalizumab were administered subcutaneously every 2 to 4 weeks according to the US product label, depending on the patient's body weight and baseline serum IgE.
Customized allergen extracts were prepared centrally for each patient based on his/her specific skin test results. Four vials containing dilutions of the patient's extract were provided. Investigators initiated dosing according to the protocol for the cluster dosing titration regimen, beginning with vial #4 (the most dilute) and progressing to vial #1, which was the most concentrated or "maintenance" solution. Each dose was administered subcutaneously into the deltoid region as a single injection. During study visits that required multiple IT injections, each injection was to be given at least 30 minutes apart. During weeks that required multiple visits for IT injections, each visit was to be separated by at least 48 hours.
