First, to demonstrate whether UDCA-therapy is effective in reducing total liver volume in PLD patients. |

E.5 End points |
E.5.1 | Primary end point(s) |
The main outcome measure will be the proportional change of total liver volume from baseline to 6 months as determined by CT. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
Baseline liver volume will be compared to liver volume at 24 weeks. |
|
E.5.2 | Secondary end point(s) |
• Change in absolute total liver volume
• Change in symptoms, measured by GI-questionnaire
• Change in quality of life, measured by SF-36 questionnaire
• Proportion of patients having any reduction in total liver volume after 24 weeks
• (Serious )Adverse events that occur in these 24 weeks
• TKV at baseline and after 24 weeks
|
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
For all secondary time points baseline values will be compared to values at week 24. |
