Is this trial a fit for you?

Likely a good fit

Ideal candidates are infants up to eighteen months old who are suspected of having a cow's milk allergy based on their medical history.

Probably not a fit

Patients who are older than eighteen months or have confirmed sensitization to cow's milk will not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study aims to determine whether introducing cow's milk in a hospital setting or at home is more effective for infants suspected of having non-IgE-mediated cow's milk allergy. Participants will be randomly assigned to either a double-blind placebo-controlled food challenge (DBPCFC) in the hospital or a gradual home introduction of cow's milk. The study will assess the outcomes of both methods to see if they can safely identify children who can tolerate cow's milk without developing symptoms. The goal is to improve the diagnostic process for cow's milk allergy in infants.

Why it matters

Potential benefit: If successful, this study could provide a safer and more convenient method for diagnosing cow's milk allergy in infants.

How similar studies have gone: While there is limited data on similar approaches, the study aims to address a significant gap in the diagnosis of non-IgE-mediated cow's milk allergy, making it a novel approach.
