E-B-FAHF-2, Multi OIT and Xolair for Food Allergy

• Status: Completed
• Trial end date: 2021-02-22
• Target enrollment: 0
• Participant gender: All

Summary

The purpose of this study is testing the use of Enhanced-Butanol purified-Food Allergy Herbal Formula-2 (E-B-FAHF-2) Chinese herbal therapy in combination with multi-food oral immunotherapy (OIT) and Xolair® (Omalizumab) to help children and adults who are allergic to foods be able to safely tolerate food allergens. Specifically in this protocol, the food allergens are milk, egg, peanut, almond, cashew, hazelnut, walnut, sesame, and/or wheat. Omalizumab is considered an investigational drug for the treatment of food allergies in children and adults. Investigational means it has not been approved by the Food and Drug Administration (FDA) for use in the U.S. The researchers hope to learn whether the addition of Chinese herbal therapy (E-B-FAHF-2) can improve the outcome of sustained unresponsiveness (which is the ability to consume a food allergen and pass an oral food challenge after being off treatment for 3 months) as compared to placebo (i.e. subjects with OIT/Omalizumab + herbal vs. OIT/Omalizumab + placebo), and will help adults and children be able to safely ingest the foods they are allergic to.

• ability to ingest oat or corn with no allergic reaction

Exclusion Criteria:

• If baked milk or egg are tolerated (assessed by clinical report), then milk or egg may not be included as a study allergen

• Any disorder in which epinephrine is contraindicated such as coronary artery disease, uncontrolled hypertension, and serious ventricular arrhythmias

• History of other chronic disease requiring therapy (other than asthma, atopic dermatitis, or rhinitis)

• History of eosinophilic gastrointestinal disease

• Forced Expiratory Volume-1 (FEV1) value <80% predicted or any clinical features of moderate or severe persistent asthma baseline severity (as defined by the 2007 NHLBI Guidelines) and greater than high daily doses of inhaled corticosteroids (as defined for children and adults using dosing tables from the 2007 NHLBI Guidelines).

• Use of steroid medications in the following manners: history of daily oral steroid dosing for >1 month during the past year, having 1 burst or steroid course within the past 6 months, or having >1 burst oral steroid course within the past 12 months.

• Asthma requiring >1 hospitalization in the past year for asthma or >1 Emergency Department (ED) visit in the past 6 months for asthma.

• Use of systemic steroid medications (Intravenous, Intramuscular or oral) for indications other than asthma for > 3 weeks within the past 6 months

• Inability to discontinue antihistamines for the initial day of escalation, skin testing or DBPCFC

• Use of Xolair® (omalizumab) within the past 6 months

• Known sensitivity to Xolair® (omalizumab) or to the class of study drugs

• Body weight more than 90 kg, or subjects with weight-IgE combination that yields a dose requirement greater than 600 mg dosing

• Use of beta-blockers (oral), Angiotensinogen converting enzyme (ACE) inhibitors, angiotensin-receptor blockers or calcium channel blockers

• Inability to swallow placebo capsules

• Mental illness or history of drug or alcohol abuse that, in the opinion of the investigator, would interfere with the subject's ability to comply with study requirements
