Study summary

To evaluate the efficacy of a 6-month specific oral tolerance induction (SOTI) protocol in inducing tolerance (maximal dose of raw egg emulsion tolerated) in children with severe IgE-mediated egg allergy and a history of at least 1 anaphylactic reaction after accidental exposure to egg.

Read the detailed description

Oral immunotherapy consisted in the administration of increasing amounts of raw emulsion egg. The children started with 1 drop of undiluted raw egg emulsion (0.05 ml) flavored with vanilla and cacao, hidden by the parents in the child's breakfast (cow's milk, soymilk, fruit juice or other). The dose was doubled at intervals of about one month in the day hospital. The increases in dose were customized for each subject based on the frequency and severity of side effects, or when an inter-current illness or asthma worsening intervened during the SOTI.

The investigators limited the SOTI protocol to six months for all patients, irrespective of the dose reached, in order to favor the adherence of families to the study.

When objective symptoms seemed more important (grade 2, 3 and 4 reaction), medical treatment was given. Subjects were discontinued from the study in case of severe adverse reactions (grade 5 reaction). Parents were advised they could telephone investigators 24 hours a day

What researchers measure

Primary outcomes

  1. Number of Children That Achieved Total (40 ml) or Partial (Less Than 40 ml But at Least 10 ml) Tolerance to Raw Egg

    To evaluate the efficacy of a 6-month Specific Oral Tolerance Induction (SOTI) protocol in inducing tolerance (maximal dose of raw egg emulsion tolerated after 6 months) in children with severe IgE-mediated egg allergy and a history of at least 1 anaphylactic reaction after accidental exposure to egg.

    Time frame: baseline and 6 months

Secondary outcomes

  1. Changes in the Median Weal Diameter, Using Egg White SPTs, End-point SPT and PP

    Before and after SOTI, we evaluated the change in the median weal diameter in millimeters, using egg white SPTs, end-point SPT and PP.

    Time frame: Baseline and 6 months

Timeline

Tracking since Sep 25, 2026
Not marked actual or estimatedDates not marked actual or estimated

The record gives a start of Jan 2008, a primary completion of Jun 2010 and a completion of Jun 2010. It does not say whether these dates are actual or estimated.

Results were first posted in Aug 2011, 1 year 2 months after primary completion.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Sep 20, 2011, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
