Inclusion criteria

  1. Written has been obtained from at least one parent (or legally acceptable representative [LAR]), if applicable)
  2. Child gestational age ≥ 37 completed weeks
  3. Child aged ≥ 60 days and less than 36 months at enrollment
  4. Documented IgE-mediated CMPA no more than 6 months prior to enrollment
  5. Child is receiving a strict cow's milk elimination diet and will continue receiving this diet until the completion of the study
  6. Child's parent(s) and LAR (if applicable) is of legal age of majority, must have parental authority, must understand the informed consent form and other study documents, and are willing and able to fulfill the requirements of the study protocol

Exclusion criteria

Exclusion criteria:

  1. Child is exclusively breastfed
  2. Any chronic medical diseases (except atopic eczema), chromosomal or major congenital anomalies
  3. Congenital heart disease or treatment by B-blockers
  4. Major gastrointestinal disease / abnormalities (other than CMPA)
  5. Known or suspected soy allergy
  6. Glucose-galactose malabsorption
  7. Immunodeficiency
  8. Children who are unable to discontinue antihistamine use (excluding eye drops) within 7 days prior to a food challenge and oral use within 14 days prior to enrollment
  9. Persistent wheeze or chronic respiratory disease
  10. Severe uncontrolled eczema or urticaria
  11. Rice protein allergy or intolerance (e.g., rice protein-induced enterocolitis syndrome), or allergy to any ingredient in the formulas
  12. Child's parent has other medical or psychiatric condition that, in the judgement of the Investigator, would make the child inappropriate for entry into the study
  13. Currently participating or having participated in another interventional clinical study within 4 weeks prior to enrollment
  14. Child's parents have not reached legal age of majority (18 years).
Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

What researchers measure

Primary outcomes

  1. Hypoallergenicity of a Hydrolyzed Rice Protein-based Formula (Experimental Formula)

    by measuring the proportion of participants who "passed" the food challenge test, meaning who consumed all doses and exhibited no allergic reactions to any of the doses of the experimental formula.

    Time frame: during test day

Secondary outcomes

  1. Gastrointestinal tolerance of experimental formula during at home consumption period

    by evaluating gastrointestinal symptoms, using information recorded by parents daily in a diary

    Time frame: during 7 days

  2. Safety of experimental formula during the at-home consumption

    By assessing the frequency and severity of adverse events reported by parents during the home usage phase

    Time frame: during 7 days
