A Single Patient Observational Trial of an Exclusive Human Milk Diet to Provide and Evaluate Growth in a Single Infant at Home With Complex Congenital Heart Disease

A single patient observational study to evaluate growth velocity and clinical outcomes of an infant status post cardiac surgery who has failed to grow well and demonstrated intolerance to cow milk-based and elemental formulas and fortifiers on a 100% human milk diet. Human milk is defined as expressed human milk or donor milk and its derivatives, human milk-based fortifier and human milk caloric fortifier.

The study hypothesis is that this infant if fed an exclusive human milk diet will have improved growth in part due to data greater tolerability of the diet.

It is estimated that the study will require 90 days to complete. Growth in safety observations will be collected only during the time the patient is receiving the diet.

The primary objective is to evaluate growth velocity (weight velocity [g/kg/day] of a single infant receiving a 100% human milk diet including a human milk based human milk fortifier formulated for term infants who are fluid restricted due to surgically correctable congenital conditions. This will be compared to the infant's growth velocity prior to the initiation of said diet.
