Nestlé Health Science presents new data showing HMO blend is safe and effective in infants with severe cow’s milk protein allergy


Nestlé Health Science presents first data at the EAACI Hybrid 2021 Congress from the PLATYPUS study, a key study in its breakthrough clinical trial program evaluating the safety and benefits of Nestle’s breastmilk-identical Human Milk Oligosaccharides blend (HMO;2’FL and LNnT) in infants and young children with cow’s milk protein allergy (CMPA).


The data presented showed that the amino acid-based formula, Alfamino® HMO, following the addition of Nestle’s HMO blend, is safe, promotes normal growth and is effective specifically for those with moderate-severe CMPA, a particularly vulnerable patient population.1


Data already presented from studies in the same clinical trial program (IVORY and CINNAMON) showed that Althéra® HMO, an extensively hydrolysed formula supplemented with the same HMO, is safe, hypoallergenic, reduces the risk of respiratory tract infections, positively shapes the gut microbiome and supports normal growth in the wider population of infants with CMPA.2,3,4,5


These studies also corroborate findings from another Nestlé-sponsored clinical trial with healthy infants fed a standard infant formula containing the same HMO blend, where it was shown to shift the gut microbiota closer to that of healthy breastfed infants, which was linked to fewer lower respiratory tract infections and lower use of antibiotics.6,7



HMO are the third largest solid component in breast milk.8 While protective benefits of HMO have been recognized for several decades, the production of breast milk-identical HMO has only recently become possible.8 2’FL and LNnT are two of the most significant HMO in breast milk.8


HMO are potentially valuable components to support the most vulnerable with CMPA which is an immune-mediated disease. Symptoms may affect the digestive, skin, respiratory systems,9 but it’s less known that CMPA is also associated with increased gut permeability and a disturbed gastrointestinal microbiota (dysbiosis).10,11 This is thought to delay immune maturation and contribute to a higher risk for infections. 8,12-14



The PLATYPUS study, conducted in Australia, is the first to evaluate infants with moderate-severe CMPA being fed a hypoallergenic amino acid-based formula (AAF) supplemented with HMO.1 In addition, very few AAF are tested in the target moderate-severe CMPA patient population, which makes the PLATYPUS study unique.1


Professor Michael Gold, Department of Allergy and Clinical Immunology, University of Adelaide, Australia, the principal investigator from the PLATYPUS study said, “The addition of two HMO to an amino acid based formula prescribed for infants with moderate to severe CMPA was well tolerated and highlighted the safety of HMO in this patient population”. 1


Nestlé Health Science is committed to leading HMO research in infants with CMPA. It has commenced a global launch of the extensively hydrolyzed (Althéra® HMO and Alfaré® HMO) and amino acid-based (Alfamino® HMO) formula portfolio with 2’FL and LNnT for the management of infants with CMPA and/or multiple food allergies. Further data on the microbiome and metabolome from the CINNAMON and PLATYPUS studies is expected in 2021 and 2022.



IMPORTANT NOTICE: Mothers should be encouraged to continue breastfeeding even when their infants have cow’s milk protein allergy. This usually requires qualified dietary counseling to completely exclude all sources of cow’s milk protein from the mothers’ diet. If a decision to use a special formula intended for infants is taken, it is important to give instructions on correct preparation methods, emphasizing that unboiled water, unsterilized bottles, or incorrect dilution can all lead to illness. Formula for special medical purposes intended for infants must be used under medical supervision.
