Pre-assignment details
DB Phase: A total of 181 subjects were randomly assigned to receive placebo, seladelpar 10 mg/day, seladelpar 20 mg/day, or seladelpar 50 mg/day (1:2:2:2 ratio). Subjects were stratified by diabetic status (yes/no) and fibrosis stage (F1 versus F2-3). Study drug (placebo or seladelpar) was taken in a blinded manner orally once a day for a period of 52 weeks. OLE Phase: All subjects will receive seladelpar 50 mg regardless of dose received during the DB phase.
