Healthy subjects:

• Healthy males and females according to a complete medical history, including a physical examination, vital signs (Blood Pressure, Pulse Rate), 12-lead Electrocardiogram, and clinical laboratory tests. The healthy subjects must meet the matching criteria based on the matching approach (cf. Section 3.3).
• Age =18 and =75 years
• Body Mass Index =18.5 and =34 kg/m2
• Creatinine clearance >70 mL/min according to Cockroft & Gault (for healthy volunteers, cf. Section 10.2)
• Signed and dated written informed consent prior to admission to the study in accordance with Good Clinical Practice and the local legislation. Hepatically impaired subjects as determined by a hepatologist/ gastroenterologist:
• Male and female liver impaired subjects determined by results of screening classified as Child-Pugh A; Child-Pugh score of 5-6 points or as Child-Pugh B; Child-Pugh score of 7-9 points, cf. Section 10.2. Child-Pugh criteria must be stable for at least 3 months prior to screening and during the trial.
• Age =18 and =75 years
• Body Mass Index =18.5 and =34 kg/m2
• Creatinine clearance >40 mL/min according to Cockroft & Gault (for liver impaired subjects, cf. Section 10.2)
• Signed and dated written informed consent prior to admission to the study in accordance with Good Clinical Practice and the local legislation.

For all females:

• Postmenopausal female subjects (postmenopausal defined as at least 1 year of spontaneous amenorrhea [in questionable cases or spontaneous amenorrhea below 1 year a blood sample with simultaneous follicle stimulating hormone (FSH) above 40 IU/l and estradiol below 30 ng/l is confirmatory]) or adequate contraception* for female subjects of childbearing potential during the study and until 2 months after study completion, e.g. any of the following: implants, injectables, combined oral contraceptives, IUD (intrauterine device), sexual abstinence for at least 1 month prior to first study drug administration, vasectomised partner (vasectomy performed at least 1 year prior to enrolment), or surgical sterilisation (including hysterectomy). Females, who do not have a vasectomised partner, are not sexually abstinent or surgically sterile have to use an additional barrier method (e.g. condom).
