Main question: What percentage of children can tolerate eggs after oral immunotherapy, compared with children who avoid eggs?
Children are assigned to these two groups by chance.
Children receiving oral immunotherapy will:
- Take a small, increasing amount of raw egg daily for 1-1.5 years
- Attend clinic or online visits each time the dose is increased
- Record missed doses
All children will:
- Provide blood samples to measure allergy-related markers
- Undergo an oral food challenge with raw egg after 1-1.5 years to assess how much they can tolerate
- Report allergic reactions (parent-reported)
- Complete questionnaires (parent-reported)
- Participate in an end-of-study telephone interview with an allergy nurse (parent-reported)

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Oral immunotherapy with eggOther
Oral immunotherapy with raw egg for 1-1.5 years
| Study group | Role | What they receive |
|---|---|---|
| Oral immunotherapy | Experimental | Children randomized to oral immunotherapy will ingest a daily dose of raw egg. Dose escalation will be performed approximately every two weeks at the allergy clinic or via online consultations. After approximately 6 months, a maintenance dose of 300 mg food protein will be reached and continued daily for 6-12 months. Receives: Other: Oral immunotherapy with egg |
| Avoidance | No intervention | Children randomized to avoidance will receive standard care for egg allergy, namely avoidance of eggs. |
What is being measured
The primary outcome is the main question the study is designed to answer.
Tolerance to eggs (4000 mg)
Proportion of children who tolerate a cumulative dose of 4000 mg of raw egg protein at an oral food challenge
Measured: 1-1.5 years after enrollment
Secondary outcomes (9)
Early tolerance to eggs (4000 mg)
Proportion of children, with a 50% or greater reduction in egg-specific immunoglobulin E (IgE) after 1 year, who tolerate a cumulative dose of 4000 mg of raw egg protein at an oral food challenge
Measured: 1 year after enrollment
Tolerance to eggs (1000 mg)
Proportion of children who tolerate a cumulative dose of 1000 mg of raw egg protein at an oral food challenge
Measured: 1-1.5 years after enrollment
Eliciting dose
Change in cumulative eliciting dose at an oral food challenge (mg raw egg protein)
Measured: At enrollment and 1-1.5 years after enrollment
Allergic reactions
Proportion of children experiencing allergic reactions to eggs outside the oral food challenge, the number of reactions per child, and the severity of the reactions (World Allergy Organization grading system, grade 1-5; higher grades indicate more severe reactions)
Measured: 6 months, 1-1.5 years, and 2-2.5 years after enrollment
Use of adrenaline auto-injector
Proportion of children for whom an adrenaline auto-injector was used due to allergic reactions to eggs outside the oral food challenge, and the number of uses per child
Measured: 6 months, 1-1.5 years, and 2-2.5 years after enrollment
Severity of allergic reactions at the oral food challenge according to the World Allergy Organization Grading System
Severity of allergic reactions to raw eggs at the oral food challenge, graded by the World Allergy Organization grading system (grade 1-5; higher grades indicate more severe reactions)
Measured: 1-1.5 years after enrollment
Parental food allergy-related quality of life
Changes in quality of life scores measured by the Food Allergy Quality of Life - Parental Burden Questionnaire (FAQL-PB). Total scores range from 0 to 102, with higher scores indicating worse food allergy-related quality of life
Measured: At enrollment, 1-1.5 years, and 2-2.5 years after enrollment
Parental food allergy-related anxiety
Changes in anxiety scores measured by the Impairment Measure for Parental Food Allergy-Associated Anxiety and Coping Tool (IMPAACT). Total scores range from 0 to 196. Subscale scores are also reported: Cognitive subscale (range 9 to 63), Behavioral subscale (range 9 to 63), Anxiety impact (range 8 to 56), and Child coping (range 2 to 14). For all scores, higher values indicate greater food allergy-related burden.
Measured: At enrollment, 1-1.5 years, and 2-2.5 years after enrollment
Changes in specific IgE
Changes in egg-specific and Gal d 1 (ovomucoid)-specific IgE (kU/L)
Measured: At enrollment, 1-1.5 years, and 2-2.5 years after enrollment

This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Laura O Kettner, MD, PhD (+45 51703229, lauchr@rm.dk), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Tolerance to eggs (4000 mg) (time frame: 1-1.5 years after enrollment). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT07888439, which also lists 4 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
