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.
|Eligible Ages||6 Months - 16 Years|
Inclusion Criteria:1. Children ≥6 months and <16 years old; 2. Suspected IgE-mediated food allergy defined by:
- - History of an immediate-type allergic reaction to a specific food or.
- - No history of consumption of the specific food or.
- - IgE sensitisation documented by skin prick test (≥1 mm) or serum specific IgE (≥0.10 KU/L); 3.
Exclusion Criteria:1. Clinically significant chronic illness other than atopic diseases; 2. Previous history of severe life-threatening reaction to the suspected food with documented decrease in oxygen saturation (<90%), hypotension (≥20% reduction in systolic blood pressure) and/or admission to intensive care; 3. Unwillingness to comply with study procedures, namely to undergo a diagnostic food challenge; 4. Contra-indication for diagnostic food challenge, namely:
- - Uncontrolled atopic diseases (e.g. eczema, asthma, rhinitis); - Chronic medical conditions that pose significant risk in the event of anaphylaxis or treatment of anaphylaxis (e.g. cardiac disease, severe lung disease, pregnancy, mastocytosis); - Inability to discontinue medications that might interfere with assessment or safety (e.g. antihistamines, β-agonists, β-blockers, NSAIDs, ACE inhibitor, antacids); - Recent (within 7-14 days) treatment with systemic steroids or prolonged high-dose systemic steroids or immunosuppressants; 5.
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.

: Food allergic
Patients with a positive oral challenge to the food being studied.
: Non food allergic
Patients with a negative oral challenge to the food being studied.
Diagnostic Test: - Oral food challenge
Patients with suspected food allergy will undergo clinical and dietary assessments and oral food challenge. Different allergy tests will be performed, including skin prick test, specific IgE test and basophil activation test, and its diagnostic utility will be determined against the clinical gold-standard.
