Pharmacokinetics of Empagliflozin (BI 10773) in Patients With Impaired Liver Function

The main objective of this study is to assess the effect of mild, moderate and severe hepatic impairment on the pharmacokinetics, safety and tolerability of BI 10773 following oral administration of BI 10773 as a single dose.

8. Use within 10 days prior to administration or during the trial of drugs which might reasonably influence the results of the trial based on the knowledge at the time of protocol preparation
9. Participation in another trial with an investigational drug within 2 months after a multiple dose study or within 1 month after a single dose study.
10. Smoker (more than 10 cigarettes or 3 cigars or 3 pipes per day).

16. Any laboratory value outside the reference range that is of clinical relevance.
17. Inability to comply with dietary regimen of study centre.
18. Subjects not able to understand and comply with protocol requirements, instructions and protocol-stated restrictions.

    Hepatically impaired subjects (group 2-4):
19. Decompensated gastrointestinal, respiratory, cardiovascular, metabolic, immunological or hormonal disorders.
20. For patients with severe liver impairment (Child-Pugh C): Severe concurrent renal dysfunction (e.g., due to hepato-renal syndrome) and a creatinine clearance \<40mL/min.

In dubious cases, a case by case decision will be made after consultation with the sponsor.
