Hepatic impairment:

• History or presence of any non-controlled and clinically significant disease that could affect the study outcome or that would place the patient at undue risk.

• Treatment with certain drugs

Healthy subjects:

• History or presence of any clinically significant disease of any major system organ class including (but not limited to) cardiovascular, metabolic, renal, neurological or psychiatric diseases.
