A positive pruritus assessment was defined as a scratching score of <=1 or at least a 1-point drop from baseline on the Albireo ObsRO instrument.
The percentage of positive pruritus assessment was calculated as the number of positive pruritus assessments divided by the total number of reported assessments recorded by each participant multiplied by 100.

Height was measured using certified stadiometer.
Change in growth parameters was assessed using linear growth (height) compared to standard growth curve (Z-score) calculated by using the software or methods from the Centers for Disease Control (CDC) website for participants with age >=2 years old and from the World Health Organization (WHO) website for participants with age <2 years old.
A Z-score was not calculated for participants whose accurate age was not available.
Baseline was the last available assessment prior to first dose of study treatment in the A4250-008 study.
A Z-score indicates how many standard deviation's (SD) a participant's height measurement, was from the average for their age and sex.
A Z-score of 0 represents the median or 50th percentile, while positive or negative values show how far above or below average a measurement was.

Prazo: Baseline and Weeks 12, 24, 36, 48, 60, 70, 72, 88, 104, 120, 136, 152, 168, 184, 200, 216, 232, 248, 264, 280, 296, 312, and 328

BMI was calculated by weight (kg) / height (m)^2 which were measured by the standardized assessments.
Change in growth parameters was assessed using linear growth (BMI) compared to standard growth curve (Z-score), calculated by using the software or methods from the CDC website for participants with age >=2 years old and from the WHO website for participants with age <2 years old.
A Z-score was not calculated for participants whose accurate age was not available.
Baseline was the last available assessment prior to the first dose of study treatment in the A4250-008 study.
The Z-score indicates how many SDs a participant's BMI measurement, was from the average for their age and sex.
A Z-score of 0 represents the median or 50th percentile, while positive or negative values show how far above or below the average a measurement was.

Change From Baseline to Week 72 During Treatment Period and During the Optional Extension Period in Pediatric End-Stage Liver Disease (PELD) Score
Prazo: Baseline and Weeks 72, 88, 104, 120, 136, 152, 168, 184, 200, 216, 232, 248, 264, 280, 296, and 312

The PELD score was calculated for children under 12 years of age, ranged across negative to positive values.
Calculation of PELD score was done by converting the laboratory parameters: total bilirubin in milligram/deciliter (mg/dL), albumin in gram (g)/dL, and creatinine in mg/dL laboratory parameters were converted to units.
PELD score was calculated as 4.80*ln (total bilirubin)+18.57*ln
[international normalized ratio (INR)] - 6.87*ln (albumin) + 4.36 (if participant <1 year: scores for participants listed for liver transplantation before the participant's first birthday continued to include the value assigned for age (<1 year) until the participant reached the age of 24 months)+6.67
(if the participant has growth failure [<-2 SD]).
The laboratory values <1.0 were set to 1.0 for the calculation of PELD score.
Lower scores represent less severe hepatic disease.
Baseline was the last available assessment prior to the first dose of study treatment in the A4250-008 study.

Change From Baseline to Week 72 During Treatment Period and During the Optional Extension Period in Model for End-stage Liver Disease (MELD) Score for Children 12 Years of Age or Older
Prazo: Baseline and Weeks 72, 88, 104, and 120
|
MELD score was calculated for children 12 years of age or older ranges from 6 to 40.
Calculation of MELD score was done by converting the laboratory parameters in the following units: total bilirubin in mg/dL, albumin in g/dL, and creatinine in mg/dL laboratory parameters were converted to units.
MELD score was calculated as 9.57*ln (creatinine)+3.78*ln
(total bilirubin)+11.2 *ln (INR)+6.43.
Laboratory values <1.0 were set to 1.0 and serum creatinine values >4.0 mg/dL were set to 4.0 for calculation of the MELD score.
Lower scores represent less severe hepatic disease.
Baseline was the last available assessment prior to the first dose of study treatment in the A4250-008 study.
All assessments after intercurrent events (premature treatment discontinuation, death, or initiation of rescue treatments such as biliary diversion surgery or liver transplantation) or follow-up assessments (>= last dose day+15 days) were excluded from analysis.

Change From Baseline to Week 72 in Aspartate Aminotransferase (AST) to Platelet Ratio Index (APRI) Score
Prazo: Baseline and Week 72
|
The AST to APRI score was calculated as [(AST in units per liter {U/L})/ (AST upper limit of normal {ULN} in U/L)] * 100/ (platelets in 10^9/L).
The APRI score is a way to assess fibrosis of the liver.
The lower the APRI score (< 0.5), the greater the negative predictive value and ability to rule out cirrhosis; the higher the value (> 1.5) the greater the positive predictive value and ability to rule in cirrhosis.
Lower values indicate less severe hepatic fibrosis.
Baseline was the last available assessment prior to the first dose of study treatment in the A4250-008 study.

Change From Baseline to Week 72 in Fibrosis-4 (Fib-4) Score
Prazo: Baseline and Week 72
|
Fib-4 score was calculated as (age * AST in U/L)/ (platelets in 10^9/L *√ ( alanine aminotransferase [ALT] in U/L).
The FIB-4 score estimates the amount of scarring in the liver.
A FIB-4 score <1.45 has a negative predictive value of 90% for advanced fibrosis (Ishak fibrosis score 4-6 which includes early bridging fibrosis to cirrhosis).
In contrast, a FIB-4 score > 3.25 would have a 97% specificity and a positive predictive value of 65% for advanced fibrosis.
Lower values indicate less severe hepatic fibrosis.
Baseline was the last available assessment prior to the first dose of study treatment in the A4250-008 study.
