Inclusion Criteria:

• 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.
• Male, between 18 and 45 years of age inclusive, at the time of signing the informed consent.
• Male subjects with female partners of child-bearing potential must agree to use one of the contraception methods listed in Section 8.1. This criterion must be followed from the time of the first dose of study medication until the follow up visit.
• Body weight ≥ 50 kg and BMI within the range 18.5 - 29.9 kg/m2 (inclusive).
• Heart rate within the range 50 - 85 bpm (inclusive) and blood pressure range between 115/60 - 140/90 mmHg (inclusive) at Screening and Day 1.
• Capable of giving written informed consent, which includes compliance with the requirements and restrictions listed in the consent form.
• Single QTcF < 450 msec.
• 24-hour Holter monitoring at screening within normal limits.
• Peripheral veins suitable for venous blood sampling and cannulation

Exclusion Criteria:

• 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).
• A positive pre-study drug/alcohol screen.
• A positive test for HIV antibody.
• Have history of any pre-existing cardiac arrhythmias (including sinus tachycardia, atrial fibrillation or flutter) or finding on baseline examination that, in the opinion of the investigator, may place the subject at an unacceptable risk as a participant in this trial or may interfere with interpretation of cardiovascular safety results during the conduct of the trial.
• Current or history of asthma (with the exception of a history of asthma in childhood only).
• Urinary cotinine levels indicative of smoking or a history of regular use of tobacco nicotine-containing products within 6 months prior to screening.
• History of regular alcohol consumption within 6 months of the study defined as: an average weekly intake of greater than 21 units. One unit is equivalent to 8 g of alcohol: a half-pint (approximately 240 ml) of beer, 1 glass (125 ml) of wine or 1 (25 ml) measure of spirits.
• The subject has participated in a clinical trial and has received an investigational product within the following time period prior to the dosing day in the current study: 90 days, 5 half-lives or twice the duration of the biological effect of the investigational product (whichever is longer).
• Exposure to more than four new chemical entities within 12 months prior to the first dosing day.
• Use of prescription or non-prescription drugs, with the exception of simple analgesics but including vitamins, herbal and dietary supplements (including St John's Wort) within 7 days 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.
• 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.
