Type 2 Diabetes MellitusPhase 1NCT00517283
A Study by Scintigraphy to Evaluate the Effect of Exenatide on Gastric Emptying in Subjects With Type 2 Diabetes
A Phase 1 study of Type 2 Diabetes Mellitus, run by AstraZeneca at 1 site in United Kingdom.
Trial summary
As exenatide slows the rate at which materials leave the stomach, it is likely to alter the rate of intestinal absorption of oral drugs when administered within a certain timeframe relative to exenatide. Read more about this study

About this study
As exenatide slows the rate at which materials leave the stomach, it is likely to alter the rate of intestinal absorption of oral drugs when administered within a certain timeframe relative to exenatide. In addition, the residence time within the stomach of other medication may be prolonged and data from this study will help assess the change in residence time in the presence of therapeutic doses of exenatide. This study will also evaluate the relationship between blood levels of exenatide and parameters measuring rate of stomach emptying.

What is being measured
The primary outcome is the main question the study is designed to answer.
To detect the mean difference in half gastric emptying time for a solid meal between any treatment and placebo
A dose of exenatide or placebo is given before the morning meal. After eating the test meal, images will be recorded at approximately 5 minute intervals from ingestion of the test meal until 3 hours after the meal, then every 10 minutes until 6 hours after the meal. In cases where significant radioactivity is observed at 6 hours after the meal, additional scintigraphic images may be taken periodically at the discretion of the investigator, until counts approach low values for up to 12 hours after the meal.
Measured: up to 12 hours post meal consumption

Questions about this trial
What is this clinical trial studying?
A Phase 1 study of Type 2 Diabetes Mellitus, run by AstraZeneca at 1 site in United Kingdom.
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 3 inclusion and 6 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 23 Feb 2015. 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 United Kingdom. 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?
To detect the mean difference in half gastric emptying time for a solid meal between any treatment and placebo (time frame: up to 12 hours post meal consumption). 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 23 Feb 2015.
