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

August 10, 2020 updated by: Xiu-Min Li

Double-Blind, Placebo-Controlled Phase 2 Study to Assess Safety and Efficacy of Chinese Herbal Therapy and Multiple Food Allergen Oral Immunotherapy

The purpose of this study is testing the use 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.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Prior studies have shown that this Chinese herbal formulation is safe and well-tolerated in food allergic individuals. While oral immunotherapy (OIT) can lead to desensitization, it remains uncertain whether this treatment can lead to lasting protection. Therefore, this study aims to use the Chinese herbal formula in combination with OIT to determine whether sustained protection can be achieved. All subjects will receive multi-allergen OIT, along with a 4 month course of omalizumab to provide added safety for the initial dose escalation and build up phases. Subjects will be randomized to receive active Chinese herbal formula or placebo. Subjects will be treated with OIT for 2 years and then food challenges will be performed to assess for desensitization. For those who achieve desensitization, all treatments will be discontinued and food challenges will be performed 3 months later to assess for sustained unresponsiveness.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
