Intranasal Diagnostics in Food Allergy: a Feasibility Study (INDY)

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT02159833
Recruitment Status : Completed

Brief Summary:
The investigators will conduct low-dose intranasal allergen challenges on children/adolescents with a diagnosis of food allergy to egg/cow's milk/soya/wheat/peanut. The data will be used to determine the safety and potential utility of intranasal food challenges in the diagnosis of food allergy.

Condition or disease Intervention/treatment Phase
Food Allergy Other: Intranasal challenge with active substance (food protein) Other: Intranasal challenge with placebo Not Applicable

Arm Intervention/treatment
Experimental: Intervention
Intranasal challenge with food protein or vehicle control
Other: Intranasal challenge with active substance (food protein)
Other: Intranasal challenge with placebo
Other Name: placebo = 0.9% NaCl saline solution

Primary Outcome Measures :
  1. Physiological response to intranasal challenge with a food protein [ Time Frame: 20mins ]
    The physiological response to food (egg/cow's milk/soya/wheat/peanut) protein when administered into the human nasal airway in food-allergic children with the corresponding food allergy. This will be assessed objectively (using acoustic rhinometry and peak nasal inspiratory flow) as well as subjectively (using a validated Symptom Scoring questionnaire).

Secondary Outcome Measures :
  1. Intranasal threshold to food protein [ Time Frame: 20 mins ]
    The intranasal threshold to food (egg/cow's milk/soya/wheat/peanut) protein to elicit a local physiological response in food-allergic children (with the corresponding food allergy), as defined by objective assessment described above.
