Outcome

Type Measure Description Time frame Safety issue
Primary Proportion of Positive Pruritus Assessments at the Participant Level Over the 24-week Treatment Period Based on the Albireo Observer-reported Outcome (ObsRO) Instrument (United States Primary Endpoint) ObsRO instrument was used to assess severity of observed scratching twice a day (AM and PM) with score from 0 to 4 where 0 is no scratching and 4 is worst possible scratching. A positive pruritus assessment was defined as a scratching score of <= 1 or at least one point drop from baseline. At each post baseline assessment over the 24-week treatment period, the AM score was compared to the baseline AM average and the PM score was compared to the baseline PM average. Both AM and PM pruritus assessments were included in the analysis. Any intermittently missing assessment or missing planned assessment after premature treatment discontinuation, death, or initiation of rescue treatment was classified as negative assessment. Proportion of positive pruritus assessments at the participant level over the 24-week was then calculated. Full analysis set was used for the analysis. Over 24 weeks of treatment
Primary Percentage of Participants Experiencing at Least a 70% Reduction in Fasting s-BA Concentration From Baseline to the End of Treatment or Reaching a Level <= 70 µmol/L After 24 Weeks of Treatment (European Union and Rest of the World Primary Endpoint) Fasting s-BA baseline was calculated as the average of the last 2 values prior to the first dose. The end value was the average of the values at Weeks 22 and 24 after the start of double-blind treatment. Participants who had at least 70% reduction in Fasting s-BA from baseline to the end of treatment or reached <=70 µmol/L after 24 weeks of treatment were considered as responder. Participants with missing average at the end of treatment were classified as non-responder. Full analysis set was used for the analysis. Over 24 weeks of treatment
