Inclusion Criteria:

• Healthy as determined by a responsible and experienced physician, based on a medical evaluation including medical history, physical examination, laboratory tests and ECG. 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. In any case, liver function tests must be strictly within the normal range at screening.
• Male between 18 and 65 years of age inclusive, at the time of signing the informed consent.
• Subjects must agree to use one of the contraception methods listed in Section 10.1. This criterion must be followed from the time of the first dose of study medication through at least 90 days following the dose of GSK962040.
• Body weight > or = 50 kg and BMI within the range 18.5-29.9 kg/m2 (inclusive).
• Capable of giving written informed consent, which includes compliance with the requirements and restrictions listed in the consent form.
• QTcB or QTcF < 450 msec or QTc<480msec in subjects with Bundle Branch Block based on single or average QTc value of triplicate values obtained over a brief recording period.
• Normal physical examination (physical exam demonstrates no evidence of clinically active disease or physical or mental impairment). A subject with a clinical abnormality may be included only if the Principal Investigator or physician designee considers that the abnormality will not introduce additional risk factors and will not interfere with the study procedures. Consultation with the GSK medical monitor is required before such subjects may be included.

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.
• History of regular alcohol consumption within 6 months of the study defined as an average weekly intake of >21 units. 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.
• 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).
• .Exposure to more than four new chemical entities within 12 months prior to the first dosing day.
• Participation in a clinical trial involving administration of 14C-labelled compound(s) within the last 3 months.
• 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 inducer) 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.
• Where participation in the study would result in donation of blood or blood products in excess of 500 mL within a 90 day period.
• Unwillingness or inability to follow the procedures outlined in the protocol.
• Subject is mentally or legally incapacitated.
• Consumption of red wine, Seville oranges, red wine, grapefruit or grapefruit juice, apple juice, vegetables from the mustard green family (e.g., kale, broccoli, watercress, collard greens, kohlrabi, brussel sprouts, mustard), and charbroiled meats from 7 days prior to the dose of study medication. .
• Radiation exposure from clinical trials, including that from the present study, excluding background radiation but including diagnostic X-rays and other medical exposures, exceeding 5 mSv in the last twelve months or 10 mSv in the last five years.
• Subject has abnormal or altered upper gastrointestinal and/or biliary anatomy.
