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

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.

Time frame: 6 weeks

Population: Safety population (all patients with ≥1 dose of study drug) who also had baseline and end of study evaluations. Data point pairs were analyzed. All patients in study 3001B3-335 originated from study 3001B3-331 or -333 and baselines from the original study they were in were used.

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.

Time frame: 6 weeks

Population: Patients who received ≥1 dose of pantoprazole and had laboratory test results. The number of patients (n) tested varied by test, variations shown (low dose, high dose): Carbon dioxide (n=7,26), CPK (n=12,42), Gastrin (n=9,25), Neutrophils (n=12,44), Platelet count (n=12,41), Urine protein albumin (n=10,38), Urine leukocyte esterase (n=10,38).
