An Extension Study of Xolair in Moderate to Severe, Persistent Asthma Patients Who Completed Study Q2143g
The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government.
Read our disclaimer for details.
This is a Phase IIIb, multicenter, open-label, extension study available to subjects who successfully complete Study Q2143g and have not participated in Study Q2195g. Subjects should be registered via the IVRS (Interactive Voice Response System) within 48 hours prior to their baseline visit. All subjects in this study will be treated with Xolair for 24 weeks. Subjects in the New Treatment Group may require additional visits for study drug injections (as frequently as every 2 weeks). Data collection during these additional visits will be limited to the assessment of adverse events. The study will evaluate all serious and nonserious adverse events, laboratory assessments, data on asthma exacerbations, and concomitant medication usage.
