NCT00084097 ↗	Omalizumab to Treat Eosinophilic Gastroenteritis	Completed	National Institute of Allergy and Infectious Diseases (NIAID)	Phase 2	2004-06-02	This study will evaluate the safety and usefulness of omalizumab (anti-IgE, Xolair) in reducing eosinophil counts and improving symptoms in patients with eosinophilic gastroenteritis (EG). EG is a disorder of unknown cause in which eosinophils, a type of white blood cell, are increased in the blood and gut tissue. Patients with EG have symptoms like stomach pain, bloating, and vomiting. About 50 percent of EG patients have food or environmental allergies, which may play a role in EG. Some patients with EG improve significantly on diets avoiding foods to which they are allergic. Immunoglobulin E (IgE) is an antibody that plays an important role in initiating allergic reactions. Omalizumab is a monoclonal antibody directed against IgE. The Food and Drug Administration approved omalizumab in 2003 for treating patients 12 years of age and older with allergic asthma. Patients between 12 and 76 years of age with eosinophilic gastroenteritis who have a blood eosinophil count of 500 or more and who have a food allergy or allergy to an inhaled allergen may be eligible for this study. Candidates are screened with a medical history, physical examination, and blood and urine tests. Participants undergo the following procedures: - Leukapheresis. This procedure is done to collect quantities of white blood cells to study the effects of omalizumab on eosinophils and other immune substances. Blood flows from a needle placed in an arm vein through a catheter (plastic tube) into a machine that separates the blood into its components by centrifugation (spinning). Some of the white cells are removed and the rest of the blood (red cells, plasma and platelets) is returned to the body through a needle in the other arm. - Skin testing. Participants are tested for allergies to specific substances. A small amount of various allergens (substances that cause allergies) are placed on the subject's arm. The skin is pricked at the sites of the allergens and the skin reaction after several minutes is observed. - Upper and lower endoscopy. One or both of these procedures is done, depending on the part of the gastrointestinal tract that is involved, to examine the tract. If both procedures are done, they are performed at the same time. For the upper endoscopy, the subject's throat is sprayed with a numbing medicine and a long, flexible tube is passed through the esophagus, stomach and small intestine. For the lower endoscopy, the tube is passed through the rectum into t...
NCT00086606 ↗	A Safety and Efficacy Study of Xolair in Peanut Allergy	Terminated	Genentech, Inc.

Phase 4	2006-02-01	This was a multicenter, parallel-group, double-blind, randomized, placebo-controlled study that enrolled 333 subjects. These subjects were 12-75 years old with atopic asthma, had elevated serum total Immunoglobulin E (IgE), had a baseline forced expiratory volume in 1 second (FEV1) ≥ 80% predicted, and were on inhaled corticosteroids with or without other controller asthma medications (e.g., long-acting β2-agonists [LABAs], leukotriene receptor antagonist [LTRA], or immunotherapy).
NCT00109187 ↗	An Extension Study of Xolair in Moderate to Severe, Persistent Asthma Patients Who Completed Study Q2143g	Completed	Genentech, Inc.	Phase 3	2002-06-01	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.
NCT00109200 ↗	A Continued Access Protocol to Provide Xolair to Patients With Severe Allergic Asthma	Completed	Genentech, Inc.

Subject eligibility will be based on disease severity and asthma deterioration upon withdrawal of Xolair treatment. Subjects whose last Xolair dose was
NCT00117611 ↗	Xolair in Patients With Chronic Sinusitis	Completed	Genentech, Inc.	Phase 4	2005-07-01	The purpose of this study is to determine if treatment with the anti-IgE antibody, Xolair (omalizumab), will improve objective and subjective evidence of chronic sinusitis.
