Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
1 teaspoon of whole egg powder given orally once per day from 4 to 8 months of age. Cooked egg containing foods will be included in the infant's diet orally from 8-12 months (there will be no specified egg dose from 8-12 months of age as this will depend on family dietary practices).
Intervention code [1] 4513 0
Prevention
Comparator / control treatment
1 teaspoon of rice powder given orally once per day from 4 to 8 months of age. Cooked egg containing foods will be included in the infant's diet orally from 8-12 months of age (there will be no specified egg dose from 8-12 months of age as this will depend on family dietary practices).
Control group
Placebo

Outcomes
Primary outcome [1] 5910 0
Immunoglobulin E (IgE) mediated egg allergy defined as an allergic reaction to a raw egg challenge and associated evidence of sensitisation to egg assessed by skin prick testing where a positive skin prick test has a mean weal diameter >3mm to egg. An allergic reaction will be defined as at least 3 concurrent non-contact urticaria persisting for at least 5 minutes and/or generalised skin erthema and/or vomiting and/or anaphylaxis (evidence of circulatory or respiratory involvement) within 2 hours of ingestion of raw egg
Timepoint [1] 5910 0
At 12 months of age
Secondary outcome [1] 241962 0
Egg allergy defined as a medically observed allergic reaction to oral cooked egg exposure. An allergic reaction will be defined as at least 3 concurrent non-contact urticaria persisting for at least 5 minutes and/or generalised skin erthema and/or vomiting and/or anaphylaxis (evidence of circulatory or respiratory involvement) within 2 hours of ingestion of the cooked egg
Timepoint [1] 241962 0
At 8 months of age
Secondary outcome [2] 241963 0
Eczema severity using a standardised scoring system for atopic dermatitis/eczema(SCORAD)
Timepoint [2] 241963 0
At 8 months of age
Secondary outcome [3] 241964 0
The development of underlining and humoral and cellular immune development. This will be assessed through blood sample analysis.
Timepoint [3] 241964 0
At 12 months of age
Secondary outcome [4] 241965 0
Food allergy and/or sensitisation to allergenic foods (other than egg). Sensitisation will be defined as a positive skin prick test with mean weal diameter >3mm to a food allergen. A food allergy reaction will be defined as at least 3 concurrent non-contact urticaria persisting for at least 5 minutes and/or generalised skin erthema and/or vomiting and/or anaphylaxis (evidence of circulatory or respiratory involvement) within 2 hours of ingestion of a particular food.
Timepoint [4] 241965 0
At 12 months of age

Study design
Purpose of the study
Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Written informed consent will be obtained before participation in a screening appointment to establish trial eligibility.
Each participating infant will be assigned a unique study number and randomly allocated into one of two intervention groups. Allocation is concealed by contacting the holder of the allocation schedule at a central administration site.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
A computer generated randomisation schedule will be produced by an independent consultant. The schedule will be stratified by infant sex and feeding mode at 4 months of age.
Masking / blinding
Blinded (masking used)
