GlaxoSmithKline
  Purpose
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 10 milligram (mg) oral dose of GW856553 containing 50 microCi (µCi) of [14C] GW856553. Urine and fecal samples will be collected until 216 hour after dosing but subjects may be discharged after 168 hour if 90% of the dose is recovered and/or <1% of the dose is excreted in a 24 hour 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 a separate study to characterize and quantify metabolites in these matrices. Safety will be assessed by adverse event monitoring, vital signs, electrocardiogram (ECG) and clinical laboratory tests.
