Bioenergetic Alterations After Exenatide Administration
A Phase 4 study testing Exenatide in people with Healthy, run by University of Wisconsin, Madison at 1 site in United States.
Trial summary
The purpose of this study is to find out how exenatide causes weight loss. Specifically, the study is assessing how exenatide may change how people take in energy (energy intake), as well as how it may effect how people use energy (energy expenditure). Read more about this study

Read the detailed description
The bioenergetics study is looking at how and why the diabetes drug exenatide causes people to lose weight.Bioenergetics is the study of how your body burns calories.
Adults 18-65 who do not have diabetes and have a body mass index (BMI) between 30 and 40 may be eligible. Women who could get pregnant must be on birth control during the study and women who are pregnant cannot participate in the study.
Subjects will take exenatide for 12 weeks. There are 6 study visits in the Univ. Wisconsin Hospital General Clinical Research Center. Visits range from 1 to 6 hours and include blood and urine tests, resting metabolic rate testing over a four hour period, physical exam, ECG, and a be bone mineral density testing at another clinic during 2 clinic visits of the study.
All study procedures and testing are free of charge.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
ExenatideDrug
Also called Byetta
Exenatide dose was 5 microgram for 2 weeks that was increased to 10 microgram for 10 weeks of treatment.
| Study group | Role | What they receive |
|---|---|---|
| Exenatide | Experimental | Exenatide. Dose was 5 microgram for 2 weeks that was increased to 10 microgram for 10 weeks Each subject serves as their own control for outcome measures taken before and during drug treatment. Receives: Drug: Exenatide |
What is being measured
The primary outcome is the main question the study is designed to answer.
Change in Energy Intake Measured Before Treatment and at the End of Treatment.
Energy intake is as calculated from energy expenditure as measured by doubly labeled water and change in body energy stores before and at the end of treatment. Units are kcal/d.
Measured: 3 months
Secondary outcomes (1)
Weight Loss After Administration of Exenatide.
Body weight after overnight fast in light clothing
Measured: 3 months

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Exenatide in people with Healthy, run by University of Wisconsin, Madison at 1 site in United States.
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 4 inclusion and 14 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 9 Jan 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 States. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 9 Jan 2015). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
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?
Change in Energy Intake Measured Before Treatment and at the End of Treatment. (time frame: 3 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00623545, which also lists 2 linked publications.
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 9 Jan 2015.
