Patient with past medical history of ongoing chronic diarrhea 4. Any patient with suspected or confirmed cancers except for basal cell carcinoma 5. Patient with a past medical history of chronic kidney disease with an impaired renal function and a glomerular filtration rate <70 mL/min/1.73 m2 6. Patient with surgical history of disruption of the enterohepatic circulation (biliary diversion surgery) within 6 months prior to start of Screening period) 7. Patient has had a liver transplant or a liver transplant is planned within 6 months of randomization 8. Decompensated liver disease, coagulopathy, history or presence of clinically significant ascites, variceal hemorrhage, and/or encephalopathy 9. Patient suffers from uncontrolled, recalcitrant pruritic condition other than PFIC. 10. Patient who has been previously treated with an IBAT inhibitor whose pruritus has not responded to treatment

Primary Outcome(s)
|
Main Objective: To demonstrate the efficacy of repeated daily doses of 40 µg/kg and 120 µg/kg A4250 in children with PFIC Types 1 and 2, as determined by the following: • The proportion of patients experiencing at least a 70% reduction in fasting s-BA concentration from baseline to end of treatment or a reduction to a specified level, compared to placebo after 24 weeks of treatment • To proportion of positive pruritus assessments at the subject level over the 24-week Treatment Period
|
Primary end point(s): The proportion of patients experiencing at least a 70% reduction in fasting s-BA concentration from baseline to end of treatment or a reduction to a specified level, compared to placebo after 24 weeks of treatment
|
Timepoint(s) of evaluation of this end point: Randomization (baseline), Week 24, follow-up visit
|
Secondary Objective: • To evaluate the effect of A4250 on serum ALT concentration • To evaluate the effect of A4250 on growth • To evaluate the effect of A4250 on sleep disturbance • To evaluate the effect of A4250 on the need for surgical treatment (biliary diversion or liver transplantation) • To assess the safety and tolerability of repeated daily doses of A4250 for 24 weeks
|
Secondary Outcome(s)
|
Secondary end point(s): Secondary efficacy endpoints include the following: EU and RoW: Proportion of positive pruritus assessments at the subject level over the 24-week Treatment Period. A positive pruritus assessment is defined as a scratching score of =1 or at least a one-point drop from baseline on the Albireo ObsRO instrument. All Regions All secondary endpoints are compared to placebo. o Change from baseline to Week 12 and to Week 24 in fasting serum bile acids o Change from baseline to Week 12 and to Week 24 in serum ALT concentration o Change in growth from baseline to Week 12 and to Week 24 o Proportion of responders for pruritus scores at Weeks 12 and 24 based on the Albireo PRO and ObsRO instruments o Change in sleep parameters measured with the Albireo PRO and ObsRO instruments from baseline over the 24-week Treatment Period o Proportion of individual assessments meeting the definition of a positive pruritus assessment at the subject level over the 24-week Treatment Period; only patients =8 years of age will complete the Albireo PRO instrument o Proportion of individual assessments meeting the definition of a positive pruritus assessment at the subject level from Weeks 0-4, Weeks 0-8, Weeks 0-12, Weeks 0-18, Weeks 0-24, respectively, or the proportion of positive pruritus assessments at each 4-week interval. o Proportion of individual AM assessments meeting the definition of a positive pruritus assessment at the subject level from Weeks 0-4, Weeks 0-8, Weeks 0-12, Weeks 0-18, Weeks 0-24, respectively, or the proportion of positive pruritus assessments at each 4-week interval. o Proportion of individual PM assessments meeting the definition of a positive pruritus assessment at the subject level from Weeks 0-4, Weeks 0-8, Weeks 0-12, Weeks 0-18, Weeks 0-24, respectively, or the proportion of positive pruritus assessments at each 4-week interval. o Number of patients undergoing biliary diversion surgery or liver transplantation
