| E.2 Objective of the trial | 
| E.2.1 | Main objective of the trial | 
| The primary objective of the present study is to investigate a change in clearance of NRL 972 after 4 weeks in comparison to baseline day 1 in patients undergoing alcohol withdrawal therapy. |  | 
| E.2.2 | Secondary objectives of the trial | 
| To investigate the relationship between the pharmacokinetics of NRL972 & disease-associated clinical matrix criteria that express severity of hepatic dysfunction. 
 One of the additional secondary objective of the present study is to investigate a change in clearance of NRL 972 at the end of the alcohol withdrawal therapy (maximum: 6 weeks) in comparison to baseline day 1.
