Terminal half-life was determined over those points characterizing the elimination phase. For the remaining 5 subjects, there were 3 additional collection intervals (24 to 32, 32 to 40, 40 to 48 hours) for characterizing the terminal elimination phase. The t1/2 (breast milk) is based on the terminal elimination phase time points from this timeframe.

Body Weight Normalized Maternal Dose (BWNMD) [22] | ||||||||
End point description |
Body weight normalized maternal dose (BWNMD) was calculated as the maternal dose in microgram per day (mcg/day) divided by maternal weight in kilogram (kg) at screening. The PK parameter analysis population included subjects who received study medication and had at least 1 of the PK parameters of primary interest.

Infant Dose Expressed as Percentage of Body Weight Normalized Maternal Dose (BWNIDPCM) [23] | ||||||||
End point description |
Infant dose expressed as percentage of body weight normalized maternal dose (BWNIDPCM) was the relative infant dose (relative to maternal dose) calculated by the formula: 100 * BWNID (Body Weight Normalized Infant Dose) / Body Weight Normalized Maternal Dose (BWNMD), where tau was the dosing interval of 12 hours. The PK parameter analysis population included subjects who received study medication and had at least 1 of the PK parameters of primary interest.

Number of Subjects With Treatment Emergent Adverse Events (AEs) or Serious Adverse Events (SAEs) [24] | ||||||||||
End point description |
An AE was any untoward medical occurrence in a subject who received study drug without regard to possibility of causal relationship. An SAE was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. Treatment-emergent are events between first dose of study drug and up to 28 days after last dose that were absent before treatment or that worsened relative to pretreatment state. Safety analysis included all subjects who received at least 1 dose of study medication.
