About this study
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
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.
Read the detailed description
This will be a single-centre, open-label, two period study in healthy male subjects. Each subject will participate in two separate dosing periods. In the first dosing period, each subject will receive a 65 μg single dose of intravenous infusion containing 7.1 μCi of [14C]-GSK573719 administered over 30 minutes. In the second dosing period, each subject will receive a single 1000 μg oral dose containing 50 μCi of [14C]-GSK573719. Each study period will involve an admission to the CRO (clinical research organisation) unit of between 7 and 10 days. The two dosing periods will be separated by a wash-out of at least 28 days between doses. Screening will occur within 30 days prior to the first dosing period. Each subject will be admitted to the clinical unit on the afternoon of Day -1. Whilst subjects are in-house, blood, 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 amounts of radioactivity still being excreted after day 5. Liquid scintillation counts (LSC) will be performed daily on the 24-hour urine pools and 24-hour faeces homogenates after Day 5 to measure total radioactivity concentrations. If less than 1% of the dose is excreted in each 24 hour period on Day 6 and Day 7 for a given subject, that subject will be discharged on Day 8, after the results of the LSC counts are available, and no further samples will be collected. If excretion is higher than 1%, or if the results are inconclusive, the subject will remain in-house, and urine and faecal collections will continue at 24 hour intervals, until excretion is less than 1% on Day 8, 9 or 10; again subjects will be discharged after the results of the LSC counts are available. On the morning of Day 11, all remaining subjects will be discharged from the clinic and subjects will be notified by phone as to whether they need to continue faecal collection at home. In the event that excretion is still higher than 1% upon discharge on Day 11, subjects will continue to collect faecal samples only, at home, at 24 hour intervals up to and including Day 14. Samples collected at home will be returned to the clinic every 2-3 days. The Entero-Test will be used in Treatment Period 1 only (IV dosing). The Entero-Test will be inserted at approximately 3.5 hours pre-dose while subjects are in a fasted state and removed at approximately 2.5 hours post-dose on day 1. At approximately 0.5 hours post-dose (i.e. two hours prior to string withdrawal) a food cue will be used to stimulate gall bladder emptying. Safety data collected will include spontaneous AE (adverse event) reporting, 12-lead ECG (electrocardiogram), vital signs, nursing/physician observation and safety laboratory tests. Subjects will complete follow up assessments within 8-12 days of their last dose (this may happen on the day of discharge from the unit). Final follow up contact will then be via telephone call to the subjects 2 to 3 days after final sample collection. The duration of the study will be approximately 11 to 12 weeks for each subject.

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.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Treatment Period 1 - IV dose of GSK573719 and Treatment Period 2 - Oral dose of GSK573719 in people with Pulmonary Disease, Chronic Obstructive, run by GlaxoSmithKline at 1 site in Netherlands.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 27 Jun 2017. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Netherlands. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
AUC(0-∞), AUC(0-t), Cmax, tmax, λz and t1/2 of total drug-related material (radioactivity) and GSK573719 in plasma following intravenous and oral dosing (time frame: up to 8 days post-dose). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 27 Jun 2017.
