About this study

Official title: Metformin, Exenatide, and Glargine Insulin in Combination for Treatment of Patients With Type 2 Diabetes

This study is designed to look at how using glargine insulin with oral diabetes medications and exenatide may improve control of blood sugar levels and weight gain in type 2 diabetics.

The main study will last 32 weeks. However, all participants completing 32 weeks will be invited to continue for another 24 weeks taking the insulin and oral medication and exenatide treatment. This extension comparing insulin and oral medication with insulin and oral medication and exenatide will look at the long term weight loss/gain and blood sugar level control effects of this new drug regimen.

There is also a sub-study in the Clinical Research Center (CRC), which requires two 38-hour inpatient stays during the main study. This study offers the opportunity to study 24-hour blood sugar and metabolic patterns quantitatively.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • exenatideDrug

    Also called Byetta

    5mcg twice a day, increasing to 10mcg twice a day for 24 weeks

  • placeboDrug

    5mcg twice a day, increased to 10mcg twice a day for 24 weeks

1Active comparatorParticipants will receive exenatide as part of their diabetes treatment
Receives: Drug: exenatide
2Placebo comparatorParticipants will receive placebo rather than exenatide as part of their diabetes treatment
Receives: Drug: placebo

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The Percentage of Intent to Treat Participants Randomized and Treated in Each Arm Who Had Lab-measured A1c <6.5% at 24 Weeks of Treatment

    Measured: After 24 weeks of randomized treatment

Secondary outcomes (1)
  1. The Percentage of Per Protocol Participants Randomized and Treated in Each Arm Who Had Lab-measured A1c <6.5% at 24 Weeks of Treatment

    efficacy criteria, 50% of per protocol participants reached A1c target of <6.5%

    Measured: After 24 weeks of randomized treatment

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing exenatide in people with Type 2 Diabetes, run by Oregon Health and Science University at 3 sites 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 6 inclusion and 17 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 6 Feb 2013. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites 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. Some participants in this study may receive a placebo. 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 6 Feb 2013). 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?

The Percentage of Intent to Treat Participants Randomized and Treated in Each Arm Who Had Lab-measured A1c <6.5% at 24 Weeks of Treatment (time frame: After 24 weeks of randomized treatment). 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 6 Feb 2013.
