Clinical studies
PurAmino® significantly improved GI and skin symptoms in infants with suspected CMPA by the next physician visit.1
STUDY DESIGN (Wilsey et al. 2023): Prospective cohort analysis of de-identified patient data collected by HCPs who analyzed the clinical profiles of infants aged ≤6 months displaying symptoms consistent with suspected or diagnosed CMPA who were prescribed an AAF at enrollment (Visit 1) and whose HCPs provided symptom data at Visit 1 and the next visit (Visit 2) at 3 to 6 weeks (n = 104). Study suggests AAF may be effective for CMPA management in infants ≤6 months of age.
The percent improvement is calculated by determining the percent difference in the incidence of total presented symptoms (at different severity levels: low, moderate, and severe) between Visit 1 and Visit 2.
PurAmino® promotes catch-up weight gain.2†
STUDY DESIGN (Vanderhoof et al. 2016): Observational, prospective, multicenter study of infants (n = 30; 1-12 months of age [mean age 6.6 months]) with a birth weight of ≥1500 g, suspected CMPA (experiencing at least one persistent CMPA symptom), and a history of weight loss (≥0.5 z score) who were not responding to an extensively hydrolyzed formula. Eligible infants received an amino acid-based formula for 12 weeks. Z score improved from -1.6 (5th percentile) to -1.1 (14th percentile) (P < 0.001).
