Accepts Healthy Volunteers
Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms
An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.
An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.
Searching Both is inclusive of interventional and observational studies.

- - Must be on baseline anti-EG/EGE therapy as long as there is agreement to not change their dosage unless medically indicated.
- - Clinical symptoms (i.e., abdominal pain, bloating, vomiting, diarrhea) severe enough to impact daily life (e.g., school/work attendance, social activities) ≥ 2 days/week for 3 of the 4 weeks prior to enrollment despite treatment (such as diet, proton pump inhibitors or corticosteroids).
- - Female subjects: Women of childbearing potential (WOCBP) must use an effective form of birth control (confirmed by the Investigator).
- - Women not of childbearing potential are defined as women who are either permanently sterilized (hysterectomy, bilateral oophorectomy, or bilateral salpingectomy), or who are postmenopausal.
- - Women <50 years old would be considered postmenopausal if they have been amenorrheic for 12 months or more following cessation of exogenous hormonal treatment and follicle stimulating hormone (FSH) levels in the postmenopausal range.
- - Women ≥50 years old would be considered postmenopausal if they have been amenorrheic for 12 months or more following cessation of all exogenous hormonal treatment.
- - All male subjects who are sexually active must agree to use an acceptable method of contraception (condom with or without spermicide, vasectomy) from Visit 0 until 16 weeks after their last dose.
- - Concurrent H.
- - Other gastrointestinal disorders such as Crohn's disease, inflammatory bowel disease, or Celiac disease - Esophageal stricture that prevents the easy passage of a standard endoscope - Use of any investigational biologic drug within 6 months prior to screening - Hypereosinophilic syndrome, defined by multiple organ involvement (with the exception of atopic disease or EGID) and persistent blood absolute eosinophil count ≥1500/mcL.
- - A diagnosis of celiac disease, inflammatory bowel disease, eosinophilic granulomatosis with polyangiitis (EGPA), drug hypersensitivity or connective tissue rheumatological disorders, - History of cancer: Subjects who have had basal cell carcinoma, localized squamous cell carcinoma of the skin, or in situ carcinoma of the cervix are eligible provided that the subject is in remission and curative therapy was completed at least 12 months prior to the date informed consent, and assent when applicable was obtained.
- - A helminth parasitic infection diagnosed within 24 weeks prior to the date informed consent is obtained that has not been treated with, or has failed to respond to standard of care therapy.
- - Pregnant or nursing - Receipt of any investigational non-biologic within 30 days or 5 half-lives prior to visit 0, whichever is longer.
- - A history of known immunodeficiency disorder including a positive human immunodeficiency virus (HIV) test.
- - Any other medical illness that precludes study involvement - Positive hepatitis B surface antigen, or hepatitis C virus antibody serology, or a positive medical history for hepatitis B or C.
- - Patients who are currently receiving or have previously received benralizumab or any other type of anti-interleukin therapy (i.e. mepolizumab, reslizumab, lebrikizumab etc.) within the last 6 months or 5 half-lives whichever is longer.
- - History of anaphylaxis to any biologic therapy or vaccine.
- - Receipt of immunoglobulin or blood products within 30 days prior to the date informed consent is obtained.
This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.
Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.
Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.
Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.
Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

The disease, disorder, syndrome, illness, or injury that is being studied.
|Eosinophilic Gastritis or Gastroenteritis|
Primary Objective: To assess the efficacy of repeat subcutaneous (SC) doses of benralizumab, compared with placebo, to reduce eosinophilic inflammation in the gastrointestinal tract of patients with EG Secondary Objectives: To assess changes in endoscopic score/histological features/blood and biopsy eosinophil counts/clinical symptoms/esophageal, gastric, and duodenal tissue transcriptome changes/ before and after treatment with benralizumab. 26 subjects are planned to be enrolled into the study at Cincinnati Children's Hospital Medical Center. Qualifying Subjects will receive 3 monthly sub-coetaneous injections of benralizumab/Placebo, followed by an option six month Open Label Extension period.
This Arm is a subcutaneous dose of 30 mg of Benralizumab
Placebo Comparator: Placebo
This Arm is a subcutaneous dose of 30 mg of Placebo
Biological: - Benralizumab
Monoclonal antibody originally developed for the treatment of asthma. It is directed against the alpha-chain of the interleukin-5 receptor (CD125). Either Benralizumab or Placebo will be injected in 3 monthly doses of 30 mg, to examine the decrease in blood and tissue eosinophil counts in subjects with Eosinophilic Gastritis. This will be followed by an optional OLE period.
Biological: - Placebo
Placebo will be injected in 3 monthly doses of 30 mg, as a comparator to injection with Benralizumab to examine the decrease in blood and tissue eosinophil counts in subjects with Eosinophilic Gastritis.
