Longer-term Study of AR101 in Subjects Who Participated in a Prior AR101 Study (ARC008)
The purpose of this study is to assess AR101's safety, tolerability and efficacy over an extended dosing period.
Novel Blood Test to Predict Safe Foods for Infants and Toddlers With Food Protein-induced Enterocolitis Syndrome (FPIES)
The aim of this study is to validate a blood test that can identify safe foods for food protein-induced enterocolitis syndrome (FPIES). This study proposes a solution to the problems of FPIES by developing a new blood assay that screens a large number of foods (more than 20) in a culture plate. If this blood test is successful it may be able to identify safe foods more quickly. The study will recruit ten participants that will have 2-3 trigger foods as well as ten participants with 4 or more trigger foods.
Oral Immunotherapy in Young Children With Food Allergy
The goal of this clinical trial is to learn about oral immunotherapy in food allergic children < 30 months of age. The main question it aims to answer is: What is the clinical- and cost-effectiveness of early low-dose oral immunotherapy aimed at long-term tolerance induction. Participants will receive oral immunotherapy for 1 year with a maintenance dose of 300 mg allergenic protein and are compared with food allergic infants not receiving oral immunotherapy to compare with natural tolerance development.
Predictors of Persistent Peanut Allergy at Age 5 Years
The purpose of this study is to determine if avoidance of peanut by children with positive allergy testing to peanut in the first 5 years of life increases the likelihood of developing a persistent peanut allergy by age 5 years. To answer this question, the investigators need to determine which children with positive allergy testing to peanut have reactions after eating peanut (allergic to peanut) and which are able to tolerate eating peanut (not allergic). The investigators plan to conduct double-blind placebo-controlled peanut challenges (gold standard for peanut allergy diagnosis) for CHILD study...
Risk Factors and Biomarkers for Diagnosis and Treatment of EoE
Purpose: To validate our previously developed model of risk factors for diagnosis of eosinophilic esophagitis (EoE), and to assess the utility of serum levels of biomarkers in diagnosis and monitoring of treatment of EoE. Participants: Up to a total of 800 participants (approximately 400 with EoE and 400 without EoE) who are referred for upper endoscopy. Procedures: This is a prospective cohort study. Patients will be compared with newly diagnosed EoE to non-EoE controls, obtain baseline measures, reassess EoE patients after treatment, and also reassess untreated controls. Data collection will include questionnaire results, blood...
The Immune Directed Individualized Elimination Therapy (iDIET) Study
This is a randomized, double blind, sham-controlled, pilot/feasibility trial of individualized dietary elimination treatment.
The Significance of a Timely Food Allergy Diagnosis and Optimal Surveillance of Nutritional Status in Children
The aim of this study is to gain more knowledge on the nutritional and immunological aspects of allergy to milk and eggs in children.
A Food Additive Removal Diet for Pediatric Eosinophilic Esophagitis
Prospective, pragmatic standard of care clinical trial comparing dietary therapies of standard dairy elimination diet alone (DED) to dairy elimination plus food additive elimination (FREE)
A Prospective Study of the Four Food Elimination Diet for Treatment of Eosinophilic Esophagitis
This study is to observe the efficacy of the four food elimination diet.
A Randomized, Controlled Trial of Probiotic and Peanut Oral Immunotherapy (PPOIT) in Inducing Tolerance in Hong Kong Children With Peanut Allergy Compared With Oral Immunotherapy (OIT) Alone and With Placebo
At present there is no cure for food allergy. People with a food allergy need to avoid the food they are allergic to in order to stay safe. However we know that accidental exposure is common. Researchers have begun to look at the effectiveness of 'oral immunotherapy' as a treatment for food allergy but results have been mixed. This study is a randomized controlled trial to evaluate the effectiveness of Probiotic and Peanut Oral Immunotherapy (PPOIT) in inducing tolerance in children with peanut allergy compared with Oral Immunotherapy (OIT) alone and with Placebo. Children will take increasing doses of peanut protein and a set...
