Pharmacokinetics and Pharmacodynamics of BI 1356 in Subjects With Different Degrees of Liver Impairment as Compared to Healthy Subjects

Inclusion Criteria: * Patients with hepatic impairment determined by results of screening classified as mild (Child-Pugh class A, score 6 points), moderate (Child-Pugh class B, score 7 to 9 points) or severe (Child-Pugh class C, score 10 to 15 points) * Healthy males and females based on a complete medical history, including physical examination, vital signs (BP, PR), 12-lead ECG, and clinical laboratory tests * Subjects in the respective groups were matched with regard to age (±10 years), weight (±20%) and gender * Age 18 to 70 years, inclusive * Body mass index 18.5 to 29.9 kg/m2, inclusive * Creatinine clearance ≥80 mL/min (except for patients with severe hepatic impairment, see exclusion criteria) according to Cockroft \& Gault * Signed and dated written informed consent prior to admission to the study in accordance with good clinical practice and local legislation Exclusion Criteria: Exclusion criteria for all subjects * Surgery of the gastrointestinal tract (except appendectomy and oesophageal varices) * Diseases of the central nervous system (such as epilepsy) or psychiatric disorders or neurological disorders (except hepatoportal encephalopathy) * History of relevant orthostatic hypotension, fainting spells, or blackouts * Chronic or relevant acute infections (except non-progressive chronic hepatitis not being in a progressive state) * History of relevant allergy or hypersensitivity (including allergy to study drug or its excipients) * Use of drugs which might reasonably influence the results of the trial or prolong the QT or QTc intervals (based on the knowledge at the time of preparing the Clinical Trial Protocol) within 10 days prior to study drug administration or during the trial * Participation in another trial with an investigational drug within 2 months prior to study drug administration or during the trial * Smoking (more than 10 cigarettes, 3 cigars, or 3 pipes per day) * Inability to refrain from smoking on trial days * Alcohol abuse (more than 60 g/day) * Drug abuse * Blood donation (\>100 mL within 4 weeks prior to study drug administration or during the trial) * Excessive physical activities (within 1 week prior to study drug administration or during the trial) * Inability to comply with dietary regimen of trial site * A marked baseline prolongation of QT or QTc intervals (e.g. repeated demonstration of a QTc interval \>450 ms) * A history of additional risk factors for torsade de pointes such as heart failure, severe hypokalemia (\<3.0 mmol/L), family history of long QT syndrome Additional/modified exclusion criteria for healthy volunteers * Any finding of the medical examination (including BP, PR, and ECG) deviating from normal and of clinical relevance * Any evidence of a clinically relevant concomitant disease * Intake of drugs with a long half-life (\>24 h) within 1 month or less than 10 half-lives of the respective drug prior to study drug administration or during the trial * Any laboratory value outside the reference range of clinical relevance Additional/modified exclusion criteria for patients with hepatic impairment * Decompensated gastrointestinal, respiratory, cardiovascular, metabolic, immunological, or hormonal disorders * Patients with severe liver impairment (Child-Pugh C): Severe concurrent renal dysfunction (e.g. due to hepatorenal syndrome) and a creatinine clearance \<40mL/min * Intake of drugs with a long half-life (\>24 h) within 1 month or less than 10 half-lives of the respective drug prior to study drug administration or during the trial and intake of metformin; drugs taken for treatment of the underlying disease are excluded * Any laboratory value outside the reference range that is of clinical relevance, except for parameters related to liver impairment (e.g. albumin, bilirubin, enzymes) and liver function tests according to Child-Pugh classification Additional exclusion criteria for female subjects * Pregnancy or intention to become pregnant within 2 months of study completion * Positive pregnancy test * Lack of adequate contraception (e.g. sterilisation, intrauterine device) or have not been using a barrier method of contraception for at least 3 months prior to the study * Unwillingness or inability to use a reliable method of barrier contraception (e.g. diaphragm with spermicidal cream or jelly or condoms with spermicidal foam), during the study and up to 2 months after completion or termination of the trial * Unwillingness of partner to use condoms * Lactation period
