Study Endpoints
Primary Endpoints
Liver Volume at Baseline and at End of Treatment
Baseline and end of treatment (Month 24)

Liver volume was assessed at baseline and end of treatment by magnetic resonance imaging. Imputation methods for patients with missing values at Month 24 were applied as follows: if a patient had at least 640 days of treatment with the study drug, the last observation that was not more than 2 days after the end of treatment was carried forward. If a patient had discontinued study drug before Day 640, the 'worst' within-patient value not more than 2 days after the end of treatment was used to impute the missing value.

Mean Within-patient Percent Change From Baseline in Liver Volume
End of treatment (Month 24)

Liver volume was assessed at baseline and end of treatment by magnetic resonance imaging. Imputation methods for patients with missing values at Month 24 were applied as follows: if a patient had at least 640 days of treatment with the study drug, the last observation that was not more than 2 days after the end of treatment was carried forward. If a patient had discontinued study drug before Day 640, the 'worst' within-patient value not more than 2 days after the end of treatment was used to impute the missing value.
