| E.4 | Principal exclusion criteria |
A subject will not be eligible for inclusion in this study if any of the following criteria apply:
[1] CONCURRENT CONDITIONS/MEDICAL HISTORY (INCLUDES LIVER
FUNCTION AND QTc INTERVAL)
•To avoid recruitment of subjects with a severe COPD exacerbation, the presence of any one of the following severity criteria will render the subject ineligible for inclusion in the study:
•Need for invasive mechanical ventilation (short term (< 48h) NIV or CPAP is acceptable)
•Haemodynamic instability or clinically significant heart failure
•Confusion
•Clinically significant pneumonia, identified by chest X-ray at screening, and as judged by the Investigator.
•Subjects who have current medical conditions 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 or NIDDM) 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.
•ALT >2xULN and bilirubin >1.5xULN (isolated bilirubin >1.5xULN is acceptable if bilirubin is fractionated and direct bilirubin <35%).
•A subject with a clinical abnormality or laboratory parameter(s) which is/are not specifically listed in the exclusion criteria, outside of the reference range for the population being studied may be included if the Investigator [in consultation with the GSK Medical Monitor if required] documents that the finding is unlikely to introduce additional risk factors and will not interfere with the study procedures.
•Current or chronic history of liver disease, or known hepatic or biliary abnormalities (with the exception of Gilbert’s syndrome or asymptomatic gallstones)
•ECG indicative of an acute cardiac event (e.g. Myocardial Infarction) or demonstrating a clinically significant arrhythmia requiring treatment.
•QTcF > 450 msec or QTcF > 480 msec in subjects with Bundle Branch Block, based on single QTcF value.
•Subjects who have undergone lung volume reduction surgery.
[2] CONCOMITANT MEDICATIONS
●Subject is currently on chronic treatment with macrolides or long term antibiotics.
●Subject is being treated with long term oxygen therapy - LTOT (> 15 hours/day).
●The subject has been on chronic treatment with anti-Tumour Necrosis Factor (anti- TNF), or any other immunosuppressive therapy (except corticosteroid) within 60 days prior to dosing.
[3] RELEVANT HABITS
●History of regular alcohol consumption within 6 months of the study defined as an average weekly intake of >28 units for males or >21 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.
[4] CONTRAINDICATIONS
●History of sensitivity to any of the study medications, or components thereof (such as lactose) or a history of drug or other allergy that, in the opinion of the investigator or Medical Monitor, contraindicates their participation.
[5] DIAGNOSTIC ASSESSMENTS AND OTHER CRITERIA
●A known (historical) positive test for HIV antibody.
●Presence of hepatitis B surface antigen (HBsAg), positive hepatitis C antibody test result at screening or within 3 months prior to first dose of study treatment.
NOTE: Because of the short window for screening, treatment with GSK2269557 may start before receiving the result of the hepatitis tests. If subsequently the test is found to be positive, the subject may be withdrawn, as judged by the Principal Investigator in consultation with the Medical Monitor.
●Where participation in the study would result in donation of blood or blood products in excess of 500 mL within 56 days.
●The subject has participated in a clinical trial and has received an investigational product within the following time period prior to the first dosing day in the current study: 30 days, 5 half-lives or twice the duration of the biological effect of the investigational product (whichever is longer).
