Study design details

• Main study objective:
  The main objective of the study is to measure prucalopride concentrations in breast milk.
• Outcomes:
  1. Area Under the Milk Concentration-time Curve (AUCmilk) of Prucalopride 2. Average Concentration of Prucalopride in Milk 3. Area Under the Milk Concentration-time Curve from Time 0 to Time t Over the Dosing Interval, ; 1. Number of Infants With Adverse Events (AEs) Based on Maternal Report 2. Change in Growth (Length and Weight) During the First Year of Life in Infants 3. Infant’s Neurodevelopmental Performance Based on Ages and Stages Questionnaire-3 (ASQ-3)
• Data analysis plan:
  Primary outcomes, i.e. pharmacokinetic parameters, will be determined from the breast milk concentration-time data for prucalopride by noncompartmental analysis using actual sampling times. Summary statistics will be determined for all PK parameters. The secondary endpoints of the study are maternal report of infant AEs, growth and performance on development questionnaires. All secondary endpoints will be summarized using descriptive statistics. Means and SDs will be presented for continuous variables and frequencies and percentages will be presented for categorical variables. Associations between drug levels and infant outcomes will be explored.
