Inclusion and exclusion criteria
Inclusion criteria:
- A subject will be eligible for inclusion in this study only if all of the following criteria apply:
- Male or female between 18 and 70 years of age inclusive, at the time of signing the informed consent.
- BMI within the range 19 – 33 kg/m^2.
- Able to satisfactorily use the dry powder inhalation inhaler.
- Capable of giving written informed consent, which includes compliance with the requirements and restrictions listed in the consent form.
- Single QTcF < 450 msec; or QTcF < 480 msec in subjects with Bundle Branch Block.
- Able to satisfactorily use the dry powder inhaler. Healthy subjects:
- AST, ALT, alkaline phosphatase and bilirubin ≤1.5xULN (isolated bilirubin >1.5xULN is acceptable if bilirubin is fractionated and direct bilirubin <35%).
- Healthy as determined by a responsible and experienced physician, based on a medical evaluation including medical history, physical examination, laboratory tests and cardiac monitoring. A subject with a clinical abnormality or laboratory parameters outside the reference range for the population being studied may be included only if the Investigator and the GSK Medical Monitor agree that the finding is unlikely to introduce additional risk factors and will not interfere with the study procedures or outcome. Hepatically Impaired Subjects:
- Hepatically impaired. To be classified as hepatically impaired, subjects must have: Known medical history of liver disease with or without a known history of alcohol abuse; and A Child-Pugh score of 5-15 to cover all severities (Mild = 5-6 points; Moderate = 7-9 points; Severe = 10-15 points). The components that contribute to the CP score should be directly related to the underlying hepatic disease and not to non-hepatic disease.
- Subjects with no significant abnormality, apart from impaired hepatic function and related symptoms, or clinical examination. A subject with a clinical abnormality may be included only if the Investigator considers that the abnormality will not introduce additional risk factors and will not interfere with the study procedures. Hepatically impaired subjects with other laboratory parameters outside the reference ranges will only be included if, in the opinion of the Investigator, the result is not clinically important and introduces no additional risk factors.
A female subject is eligible to participate if she is of: •Non-childbearing potential defined as pre-menopausal females with a documented tubal ligation or hysterectomy; or postmenopausal defined as 12 months of spontaneous amenorrhea [in questionable cases a blood sample with simultaneous follicle stimulating hormone (FSH) > 40 MlU/ml and estradiol < 40 pg/ml (<140 pmol/L) (healthy subjects only) is confirmatory]. Females on hormone replacement therapy (HRT) and whose menopausal status is in doubt will be required to use one of the contraception methods in Section 8.1 if they wish to continue their HRT during the study. Otherwise, they must discontinue HRT to allow confirmation of post-menopausal status prior to study enrollment. For most forms of HRT, at least 2-4 weeks will elapse between the cessation of therapy and the blood draw; this interval depends on the type and dosage of HRT. Following confirmation of their post-menopausal status, they can resume use of HRT during the study without use of a contraceptive method. •Child-bearing potential and agrees to use one of the contraception methods listed in Section 8.1 for an appropriate period of time (as determined by the product label or investigator) prior to the start of dosing to sufficiently minimize the risk of pregnancy at that point. Female subjects must agree to use contraception until completion of the follow-up visit.
Exclusion criteria:
- A subject will not be eligible for inclusion in this study if any of the following criteria apply:
- Suffered a lower respiratory tract infection in the 4 weeks before the screening visit.
- Taken oral corticosteroids less than 8 weeks before the screening visit.

- History of sensitivity to any of the study medications, or components thereof or a history of drug or other allergy that, in the opinion of the investigator or GSK Medical Monitor, contraindicates their participation.
- Where participation in the study would result in donation of blood or blood products in excess of 500 mL within a 56 day period.
- Pregnant females as determined by positive serum or urine hCG test at screening or prior to dosing.
- Lactating females.
- The subject has been treated for or diagnosed with depression within six months of screening or has a history of significant psychiatric illness.

- If, in the opinion of the examining physician, an unstable cardiovascular, renal, hepatic, pulmonary, endocrine, metabolic, neurological, haematological or gastrointestinal condition is present or any other medical condition which the investigator considers sufficiently serious to interfere with the conduct, completion, or results of this trial or constitutes an unacceptable risk to the subject.
- Subjects with any predisposing condition that might interfere with the absorption, distribution, metabolism or excretion of drugs or any previous gastrointestinal (GI) surgery (except appendectomy or cholecystectomy more than three months prior to the study) condition which the investigator considers sufficiently significant to interfere with the conduct, completion, or results of this trial or constitutes an unacceptable risk to the subject.
- Haemoglobin values <12.9g/dL for males and <11.4g/dL for females.
- A past history or current symptoms of significant hepatic or renal disease, pancreatitis or acute cholecystitis which the investigator considers sufficiently significant to interfere with the conduct, completion, or results of this trial or constitutes an unacceptable risk to the subject.
- A positive pre-study Hepatitis B surface antigen or positive Hepatitis C antibody result within 3 months of screening
- Current or chronic history of liver disease, or known hepatic or biliary abnormalities (with the exception of Gilbert's syndrome or asymptomatic gallstones).
- An average weekly intake of >21 units for males or >14 units for females. One unit is equivalent to 8 g of alcohol: a half-pint (~240 ml) of beer, 1 glass (125 ml) of wine or 1 (25 ml) measure of spirits.
- Use of prescription or non-prescription drugs, including vitamins, herbal and dietary supplements (including St John’s Wort) within 7 days (or 14 days if the drug is a potential enzyme inhibitor) or 5 half-lives (whichever is longer) prior to the first dose of study medication, unless in the opinion of the Investigator and GSK Medical Monitor the medication will not interfere with the study procedures or compromise subject safety. In particular subjects taking steroids or medications that significantly inhibit P450 CYP3A4 (e.g. ketoconazole) must not be included in this study. Hepatically Impaired Subjects

- History of oesophageal bleeding within the last 6 months before dosing.
- Significant hepatic encephalopathy, degree of CNS impairment or other signs of hepatic function deterioration which the investigator considers sufficiently serious to interfere with the informed consent, conduct, completion, or results of this trial or constitutes an unacceptable risk to the subject.
- Patients at risk of requiring a transfusion during the study period, or has haemoglobin < 9 g/dL, or has underlying coronary artery disease (or other clinical condition) in which a reduction in haemoglobin associated with FF/GW642444M administration might be expected to cause clinical deterioration.
- Evidence of current significant infection (e.g. spontaneous bacterial peritonitis, pneumonia etc.).
- Subjects who develop symptoms such as infections or haemorrhage between screening and dosing must not be included in the study.
- Fluctuating or rapidly deteriorating hepatic function (such as, but not limited to, rapidly increasing ascites, rapidly deteriorating mental status, deteriorating hepatic function based on prothrombin time [PT], albumin, total bilirubin). Assessment of the stability of the subject’s hepatic function will be at the discretion of the Principal Investigator.

- Subjects with a diagnosis of primary biliary disease such as cholestasis or sclerosing cholangitis.
- Subjects who need to take any concomitant medication, either prescribed or over-the-counter, which may in the opinion of the Investigator, interfere in any way with the study procedure or be a safety concern (see Section 9 for the list of permitted concurrent medications). In particular subjects taking medications that significantly inhibit P450 CYP3A4 (e.g. ketoconazole) must not be included in this study.
- Subjects who, within the past six months, have had a history of significant drug abuse or alcohol abuse.
