Open Label Safety Study of Enteric-Coated Spheroid Suspension in Infants Aged Less Than 12 Months With Presumed Gastroesophageal Reflux Disease (GERD)

Primary outcomes

1. Number of Patients With Laboratory Test Values of Potential Clinical Importance During Treatment Period

   Time frame: 6 weeks

   Pre-defined criteria were established for each laboratory test to define the values that would be identified as of potential clinical importance. Criteria are as follows: Potassium ≤ 3.0 mEq/L or ≥ 6.2 mEq/L; Carbon dioxide < 12 mEq/L or > 35 mEq/L; Total bilirubin > 1.5xULN; CPK > 3xULN; Gastrin ≥ 600 pg/mL; Neutrophils < 10% or > 80%; Platelet count < 100 x10 to the third power/ul or > 600 x10 to the third power/ul; Urine protein albumin > 2+ (dipstick) 100mg/dL or positive; Urine leukocyte esterase > 2+ (dipstick) moderate or positive.

2. Growth Parameters Z-scores

   Time frame: 6 weeks

   Z-Score is a statistical measure to evaluate how a single data point compares to a standard. A Z-Score describes whether a mean is above or below the standard and how unusual the measurement is. Z-scores primarily range from -3 to +3. A Z-score of 0 indicates the same mean, >0 a greater mean, and <0 a lesser mean than the standard. In this study, infant growth parameters were compared to a standard defined by Centers for Disease Control's growth charts.
