Omalizumab to Treat Eosinophilic Gastroenteritis
A Phase 2 study testing Omalizumab in people with Gastroenteritis, run by National Institute of Allergy and Infectious Diseases (NIAID) at 1 site in United States.
Trial summary
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. Read more about this study

About this study
Official title: Pilot Study of Omalizumab in Eosinophilic Gastroenteritis
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...
Read the detailed description
Eosinophilic gastroenteritis (EG) is characterized by eosinophilic infiltration of the bowel wall, gastrointestinal symptoms, and in more than 50% of patients, peripheral eosinophilia. Approximately one half of EG patients have multiple food allergies and/or elevated immunoglobulin E (IgE), suggesting an allergic etiology. The purpose of this study is to evaluate the safety and efficacy of humanized monoclonal anti-IgE antibody, omalizumab (Xolair (Registered Trademark)), in eosinophilic gastroenteritis. Omalizumab is approved for use in asthma and is dosed subcutaneously based on serum total IgE level and body weight, with a maximum dose of 375 mg every 2 weeks. Subjects with EG, and either food hypersensitivity or environmental allergies will be admitted to the Clinical Center. All subjects will undergo a thorough clinical evaluation, including endoscopy. The primary endpoints will be the evaluation of safety of omalizumab and its efficacy in reducing peripheral blood absolute eosinophil count. In addition, the following secondary endpoints will be studied: symptom scores, study drug pharmacodynamics, and tissue eosinophilia. Blood cells and serum will be collected and evaluated in the laboratory to address issues related to the immunopathogenesis and treatment of EG. This study will provide a better understanding of inflammatory and allergy mediators in the pathogenesis of EG and may provide a potential therapy for EG. Following subcutaneous administration of the initial dose of omalizumab (maximum 375 mg), subjects will be followed as inpatients for a minimum of 24 hours to monitor for adverse effects. Subsequent doses will be administered biweekly for a total of 8 doses.

A Phase 2 study testing Omalizumab in people with Gastroenteritis, run by National Institute of Allergy and Infectious Diseases (NIAID) at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 0 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 2 Jul 2017. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Evaluation of safety of omalizumab and its efficacy in reducing peripheral blood absolute eosinophil count pre- and post-omalizumab administration.. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00084097, which also lists 5 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 Jul 2017.
