Brief Summary

Children with immunoglobulin E (IgE)-mediated cow's milk allergy (CMA) who react to small amounts of baked cow's milk may require prolonged elimination. Preliminary observations suggest that some may tolerate products prepared with a low-αs1-casein goat milk formula. This study will compare a four-step goat milk formula-based ladder (4-GMFL) with a four-step cow's milk ladder (4-CML). This exploratory open-label, multicentre, randomised trial will enroll 92 children aged 1-5 years with IgE-mediated CMA, allocated 1:1 to the 4-GMFL or 4-CML group. Both ladders comprise muffin, pancake and baked hard cheese, introduced at 4-week intervals and assessed by open, physician-supervised oral food challenges (OFCs) in hospital, followed by a final OFC with 120 mL of non-heated pasteurised cow's milk at week 12. The primary outcome will be tolerance to non-heated cow's milk protein at this final step, defined as a negative OFC with 120 mL of pasteurised cow's milk containing 3.96 g of protein. Secondary outcomes will include tolerance to individual ladder products, allergic reactions, anaphylaxis, intramuscular adrenaline use, anthropometric changes, food allergy-related quality of life, caregiver anxiety and adherence. Molecular sensitisation profiles will be explored as potential predictors of OFC outcomes.

Outcome Measures

Primary Outcomes (1)

  • Between-group difference in the proportion of children who tolerate non-heated pasteurised cow's milk

    The primary outcome will be the between-group difference in the proportion of children who tolerate non-heated pasteurised cow's milk. Tolerance will be defined as the absence of an allergic reaction during an OFC with 120 mL of pasteurised cow's milk, corresponding to 3.96 g of cow's milk protein. In both the 4-CML and 4-GMFL groups, this OFC constitutes Step 4 and the final step of the ladder.

    Non-heated pasteurised cow's milk will be administered at the end of the observation period (week 12).

Secondary Outcomes (9)

  • Between-group difference in the proportion of children tolerating the full predefined dose at Steps 1-3

    Baseline (Step 1), week 4 (Step 2) and week 8 (Step 3)

  • Between-group difference in maximum tolerated dose at each ladder step

    Baseline (Step 1), week 4 (Step 2) and week 8 (Step 3)

  • Between-group difference in the percentage of children who experienced anaphylaxis

    Measured during the observation period (12 weeks).

  • Between-group difference in the proportion of children with anaphylaxis (grades 3-5, per 2023 WAO criteria) who required epinephrine administration

    Measured during the observation period (12 weeks).

  • Between-group differences in anthropometric changes

    Measured during the observation period (12 weeks).

  • +4 more secondary outcomes

Eligibility Criteria

Age1 Year - 5 Years
Sexall
Healthy VolunteersNo
Age GroupsChild (0-17)

You may qualify if:

  • Age between 1 and 5 years.
  • Diagnosis of IgE-mediated CMA confirmed according to ESPGHAN guidelines, by a positive OFC with CMPs. In high-risk children (i.e., with a history of anaphylaxis occurring more than 6 months before enrolment) diagnosis may be established without a new OFC, based on a positive SPT wheal at least 3 mm greater than negative saline control and elevated specific IgE to CMPs \>0.35 kUa/L.
  • On a cow's milk-free, therapeutic elimination diet for at least 6 months, or since before 12 months of age.
  • Eligible regardless of the risk of systemic reaction (anaphylaxis) and asthma.
  • Overall good health status.
  • Parents/legal guardians able to understand the study procedures and communicate effectively with the study team.
  • Written informed consent provided by parents/legal guardians.
  • Expected good cooperation of the child's parents/legal guardians with the study team.

You may not qualify if:

  • Uncontrolled asthma, defined as poor control according to the current GINA criteria, recent exacerbation requiring systemic corticosteroids or the need for medium to high-dose inhaled corticosteroids to maintain control
  • Signs of acute infectious disease (i.e., acute runny nose, cough, or fever).
  • Clinically relevant, uncontrolled exacerbation of another allergic disease that, in the investigator's judgement, could compromise OFC interpretation or safety (i.e., conjunctivitis, allergic rhinitis, atopic dermatitis).
  • History of anaphylaxis due to cow's milk proteins within the last 6 months.
  • Documented tolerance to baked CMPs or to higher steps of the milk ladder.
  • Use of immunosuppressive drugs or ongoing allergen immunotherapy.
