A Study to Evaluate the Safety, Tolerability, Pharmacokinetics, and Dose-Response Relationship of Multiple Doses of GSK2269557 Administered as a Dry Powder to Chronic Obstructive Pulmonary Disease (COPD) Patients

Study Overview
=================
Brief Summary
-----------------
This is a randomised, double-blind, placebo controlled, parallel group study to evaluate the safety, tolerability, pharmacokinetics and dose response of multiple doses of GSK2269557 administered as a dry powder in COPD subjects. Pharmacodynamic effects on biomarkers will also be assessed. This study will have two parts. In Part A, subjects will be randomized to active or placebo treatment in a 3:1 ratio and in Part B, to placebo or one of the six doses of active treatment in an equal ratio. A sufficient number of COPD subjects (male and female of non-child bearing potential) will be screened to ensure that approximately 30 subjects are enrolled and at least 20 evaluable subjects are obtained for Part A and approximately 35 subjects will be enrolled for Part B. In both the parts, subjects will receive study treatment once daily for 14 consecutive days. Placebo control will be included for a valid evaluation of adverse events attributable to treatment versus those independent of treatment.

Inclusion Criteria: The subject has a confirmed and established diagnosis of COPD, as defined by the Global Initiative for Chronic Obstructive lung Disease (GOLD) guidelines. Male or female of non-child bearing potential between 40 and 75 years of age inclusive, at the time of signing the informed consent. The subject has a post-bronchodilator [400 microgram (mcg) salbutamol] Maximal amount of air FEV1/FVC <0.7 and FEV1 >=40% to <=80% of predicted (Predictions should be according to the European Community of Coal and Steel (ECCS) equations). Subject is a smoker or an ex-smoker with a smoking history of at least 10 pack years (pack years = (cigarettes per day smoked/20) x number of years smoked)). The subject is able to produce >100 milligram (mg) of sputum at screening. Body weight >=45 kilogram (kg) and body mass index (BMI) within the range 17 - 32 kg/square meter (m^2) (inclusive). A female subject is eligible to participate if she is of: Non-childbearing potential defined as pre-menopausal females with a documented tubal ligation, hysterectomy, salpingo-oophrectomy or oophrectomy; or postmenopausal defined as 12 months of spontaneous amenorrhea [in questionable cases a blood sample with simultaneous follicle stimulating hormone (FSH) > 40 milli-International units (MIU)/millilitre (mL) and estradiol < 40 picogram (pg)/mL (<147 picomole(pmol)/Liter [L]) 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, 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 enrolment. 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.]; or has only same-sex partners, when this is her preferred and usual lifestyle. Male subjects with female partners of child-bearing potential must agree to use one of the contraception methods. This criterion must be followed from the time of the first dose of study medication until the follow-up visit. Based on averaged QTcF values of triplicate ECGs obtained over a brief recording period (e.g. 5 minutes): QTcF <450 millisecond (msec); or QTcF<480 msec in subjects with right bundle branch block. Capable of giving written informed consent, which includes compliance with the requirements and restrictions listed in the consent form. A subject with a clinical abnormality or laboratory parameter(s) which is/are not specifically listed in the inclusion or exclusion criteria, outside the reference range for the population being studied may be included if the investigator [in consultation with the Glaxosmithkline (GSK) medical monitor if required] documents that the finding is unlikely to introduce additional risk factors and will not interfere with the study procedures. Exclusion Criteria: Current or chronic history of liver disease, or known hepatic or biliary abnormalities (with the exception of Gilbert's syndrome, asymptomatic gallstones and cholecystectomy). Subjects who have a past or current medical condition or diseases that are not well controlled and, which as judged by the Investigator, may affect subject safety or influence the outcome of the study. (Note: Patients with adequately treated and well controlled concurrent medical conditions (e.g. hypertension) are permitted to be entered into the study). Subject has a diagnosis of active tuberculosis, lung cancer, clinically overt bronchiectasis, pulmonary fibrosis, asthma or any other respiratory condition that might, in the opinion of the Investigator, compromise the safety of the subject or affect the interpretation of the results.

One unit is equivalent to 8 gram of alcohol: a half-pint (approximately 240 mL) of beer, 1 glass (125 mL) of wine or 1 (25 mL) measure of spirits. History of sensitivity to any of the study medications, or components (such as lactose) thereof or a history of drug or other allergy that, in the opinion of the investigator or GSK Medical Monitor, contraindicates their participation. A positive test for Human immunodeficiency virus (HIV) antibody - tested according to local policies. The subject has a positive pre-study drug/alcohol screen. A minimum list of drugs that will be screened for include cannabinoids, amphetamines, barbiturates, cocaine and opiates. The detection of drugs (e.g. benzodiazepines, opiates) taken for a legitimate medical purpose would not necessarily be an exclusion to study participation.

Vital signs (SBP, DBP, and HR) were measured at Day 1 (30 minutes [min] and 6 h post-dose), Day 7 (pre-dose), and Day 14 (24 h post-dose). All measurements were obtained in supine position, after a 5-minute rest. Day 7 assessments could be conducted on Day 7 or Day 8. | Day 1, Day 7, and Day 14 | 
| Part B: Number of Participants With Normal and Abnormal (Clinically Significant or Not Clinically Significant) Findings in 12-lead Electrocardiogram (ECG) at Any Visit Post-Baseline | Baseline was the Day 1 (pre-dose) measurement. Single 12-lead ECGs were obtained using an ECG machine that automatically calculates the HR and measures PR, QRS, QT, and corrected QT intervals. Day 7 assessments could be conducted on Day 7 or Day 8. | Day 1, Day 7, and Day 14 | 
| Part B: Forced Expiratory Volume in One Second (FEV1) and Forced Vital Capacity (FVC) at Screening and Follow-up | FEV1 and FVC are measures of lung function. FEV1 is defined as the maximal amount of air that can be forcefully exhaled in one second. FVC is defined as the maximum amount of air that can be forcibly blown out after a maximum inspiration. FEV1 and FVC measurements were repeated until three technically acceptable measurements (within 150 milliliters of each other) had been made. Only the best of three measurements were recorded. | Screening (up to 30 days prior to Day 1) and Follow-up (approximately Day 19) |
