Official Title
A Phase 3 Double-blind, Randomized, Placebo-controlled Study of the Safety and Efficacy of Odevixibat (A4250) in Patients With Alagille Syndrome (ASSERT)
Primary Outcomes
Outcome Description
Change from baseline in average AM (measured after waking up) and PM (measured before bedtime) scratching score to Month 6 as measured by the Albireo Observer-Reported Outcome (ObsRO) Instrument. The ObsRO instrument was used to assess severity of observed scratching twice a day (AM and PM) with scores from 0 to 4 where 0 is no scratching and 4 is worst possible scratching.
Outcome Measure
Change From Baseline in Scratching Score
Outcome Time Frame
Change from baseline for each four-week average pruritis score to Month 6 (Weeks 21 to 24), in which baseline was calculated based on the 14 days before the start of treatment.
Secondary Outcomes
Outcome Description
Change in serum bile acid levels (μmol/L) from baseline to average of week 20 and 24
Outcome Time Frame
Change from baseline to average of week 20 and 24, where baseline was calculated by averaging the last two values preceding start of treatment, and average of Week 20 and Week 24 was defined as the average of Week 20 and Week 24 values.
