Eligibility Criteria
Inclusion Criteria:
- Healthy male aged between 30 and 60 years inclusive, at the time of screening.

Exclusion Criteria:
- Any clinically relevant abnormality identified on the screening medical assessment, laboratory examination, or ECG (12-lead).

- A definite or suspected personal or family history of adverse reactions or hypersensitivity to the trial drug or to drugs with a similar chemical structure.
- History of regular alcohol consumption exceeding an average weekly intake of > 21 units (or an average daily intake of greater than 3 units). One unit is equivalent to a half-pint (284mL) of beer/lager; 25mL measure of spirits or 125mL of wine).

- Subjects who have had exposure to more than three new chemical entities within 12 months prior to the first dosing period.

- If participation in the study will result in the volunteer having donated more than 400mL of blood in the previous 56 days.

- History of elevated blood pressure or blood pressure persistently >140/90 mmHg at screening.
- An unwillingness to abstain from sexual intercourse with pregnant or lactating women; or an unwillingness of the subject to use a condom/spermicide in addition to having their female partner use another form of contraception such as an IUD, diaphragm with spermicide, oral contraceptives, injectable progesterone, sub-dermal implants or a tubal ligation if the women could become pregnant from the time of the first dose of the study medication until completion of the follow-up procedures.
- Lack of suitability for participation in this study, for any reason, in the opinion of the investigator.
- Any condition that could interfere with the accurate assessment and recovery of 14C.
Prescribed or over-the-counter medication within 5 days (or 5 half lives, whichever is longer) prior to the first dosing day, unless the investigator confirms that it will not introduce additional risk or interfere with the study procedures or outcome.
- Liver function tests (ALT, AST, ALP, ?GT and bilirubin) > upper limit of normal (ULN) at screening
- Creatinine phosphokinase (CPK) > ULN at screening
- Positive urine drug screen
- Positive HIV, Hepatitis B or C result at screening.
- History of use of tobacco- or nicotine-containing products within 6 months of screening or a positive urine cotinine screen (urine cotinine > 250ng/mL).

Brief Summary
SB-681323 is a p38 MAP kinase inhibitor and is currently under development by GlaxoSmithKline. This will be an open label study conducted at one site. Six healthy male subjects will be enrolled to ensure at least four fully evaluable subjects. Each subject will receive a single 10mg/ 50 µCurie oral dose of [14C]SB-681323. Urine and faecal samples will be collected until 216 h after dosing but subjects may be discharged after 168 h if 90% of the dose is recovered and/or <1% of the dose is excreted in a 24 h period. Blood and plasma will be collected at various sample times after dosing to measure parent drug and total drug-related material. Samples of urine, faeces and plasma will be transferred into separate study to characterise and quantify metabolites in these matrices. Safety will be assessed by adverse event monitoring, vital signs, ECG and clinical laboratory tests.
