Trial overview
Official title: An open-label, two period study to determine the excretion balance and pharmacokinetics of 14C-GSK573719, administered as single dose of an oral solution and an intravenous infusion, to healthy male adults
Trial description: This will be a two-period, open-label study conducted at a single site. Six healthy male subjects will participate in the study to ensure at least four fully evaluable subjects. Each subject will receive a single 1000 μg (microgram) oral dose containing 50 μCi (Micro Curie) of [14C]-GSK573719 and a 65 μg intravenous infusion containing 7.1 μCi of [14C]-GSK573719. Whilst subjects are in-house, urine and faecal samples will be collected for a minimum of 168 hours (7 days) after dosing or for up to 240 hours (10 days) depending on the amounts of radioactivity still being excreted after Day 5. Faecal sample collection may continue at home for up to 14 days. Bile samples will be collected using Entero-Test string sampling of duodenal bile. Whole blood and plasma samples will be collected at various sample times after dosing to measure parent drug (plasma only) and total radiolabelled drug related material (blood and plasma). Urine and faeces aliquots will be taken to measure total radiolabelled drug-related material. Samples of urine, faeces and plasma will be transferred into a separate study to characterize and, where possible, quantify metabolites in these matrices.
