Clinical Trial Summary

Cow's milk protein allergy is defined as an immunological reaction to one or more milk proteins. A variety of symptoms can be suggestive for cow's milk protein allergy . Cow's milk protein allergy is suspected clinically in 5-15% of infants, while most estimates of prevalence of cow's milk protein allergy vary from only 2 to 5 %. Confusion regarding cow's milk protein allergy prevalence is often due to differences in study populations, study design and a lack of defined diagnostic criteria. The importance of defined diagnostic criteria needs to be emphasised. It precludes infants from an unnecessary diet and avoids delay in diagnosis, which can lead to malnutrition. The treatment of cow's milk protein allergy is the dietary elimination of cow's milk proteins. In non-breastfed infants and children less than 2 years of age, a substitute formula is mandatory as prescribed by several international scientific societies. Extensively hydrolyzed formulas are used as therapeutic formulas. An extensively hydrolysed formula is often a whey or casein based formula in which the protein has been chopped up in smaller pieces that are less allergenic. Because of high cross-reactivity (up to 80%) and nutritional inadequacy, the use of any other animal milk or soy-based formula is precluded.The infant should be maintained on an elimination diet until the child is between 9-12 months of age or at least for 6 months, whichever occurs first. In most cases, symptoms will improve substantially within 2-4 weeks if diagnosis is correct. According to consensus in literature, a therapeutic formula is a formula tolerated by at least 90% (with 95% confidence) of cow's milk protein allergy infants. The primary study outcome will be the evaluation of the hypoallergenicity of a new aminoacid based formula in children with confirmed immunoglobulin (Ig)E- mediated CMA. According to the American Academy of Pediatrics (AAP) Subcommittee on Nutrition and Allergic Diseases a hypoallergenic formula must be tested in infants and children with hypersensitivity to cow's milk proteins, with findings verified by elimination-challenge tests under double-blind, placebo-controlled conditions (DBPCFC).

Outcome

Type Measure Description Time frame Safety issue
Primary Number of subjects tolerants to a new hypoallergenic formula demonstrated by oral food challenge with the new study formula All subjects perform an oral food challenge with the new study formula. If the infant not react to the new hypoallergenic formula during the oral food challenge, the subjects tolerate this product. After one week from the oral food challenge
Secondary Evaluation of body weight in children assuming amino acid based formula In the absence of reaction to the new amino acid based formula, a subgroup of child (n=15) will continue the second part of the study, with an open-label feeding with amino acid based formula for 180 days. after 180 days
