Paused for now. It may or may not start again.
Ongoing This study
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This study compares two timelines for gradually introducing egg to children (ages 1-18) with egg allergy who can already eat baked egg. One group follows a 12-month stepwise plan, the other a 20-month plan. The goal is to see if the shorter plan works just as well for building full egg tolerance. The study involves 62 children and tracks how many reach full tolerance within the expected time.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: 1. Children (1-18y) had or have a clinical diagnosis of IgE mediated hen's egg allergy based on positive history as well as skin prick testing and/or specific IgE detection by CAPtest in an allergy clinic 2. Children are at least 12 months old before introduction of heated egg is considered 3. Children did not suffer from grade 4 anaphylaxis due to egg-ingestion at presentation (for grade 4 anaphylaxis, see EAACI anaphylaxis guidelines, Muraro A et al, Allergy. 2014 Aug;69(8):1008-25). 4. Children have specific IgE levels to Gal d 1 below 1.2 kU/mL (12-24 months) or below 5 kU/mL (\>24 months) or have a level that predicts a good chance (\>75%) to pass the baked egg provocation test by cake (see Bartnikas LM et al, J Allergy Clin Immunol Pract 2013; 1: 354-360) and/or children passed baked egg provocation test by cake executed on clinical judgement. Exclusion Criteria: 1. Children had grade 4 anaphylaxis (for grade 4 anaphylaxis, see EAACI anaphylaxis guidelines, Muraro A et al, Allergy. 2014 Aug;69(8):1008-25) due to egg ingestion 2. Children are younger than 12 months old at the moment of passing cake open provocation test 3. Parents are not able or not willing to adhere to a certain egg step-containing diet on a regular basis at home 4. Parents and/or children are not willing to give IC/assent
