    Absolute change in HbA1c from baseline (Day 1) to Week 26 [Week 26 - Baseline].

    Measured: Day 1, Week 26

Secondary outcomes (11)
  1. Percentage of Subjects Achieving HbA1c Target of <7% at Week 26

    Measured: Week 26

  2. Percentage of Subjects Achieving HbA1c Target of <=6.5% at Week 26

    Percentages of subjects achieving HbA1c target values of <=6.5% at Week 26.

    Measured: Week 26

  3. Percentage of Subjects Achieving HbA1c Target of <=6.0% at Week 26

    Percentages of subjects achieving HbA1c target values of <=6.0% at Week 26.

    Measured: Week 26

  4. Change in Body Weight From Baseline to Week 26

    Change in body weight from baseline (Day 1) to Week 26.

    Measured: Day 1, Week 26

  5. Change in Fasting Plasma Glucose From Baseline to Week 26

    Change in fasting plasma glucose from baseline (Day 1) to Week 26.

    Measured: Day 1, Week 26

  6. Change in Systolic Blood Pressure From Baseline to Week 26

    Measured: Day 1, Week 26

  7. Change in Diastolic Blood Pressure From Baseline to Week 26

    Change in diastolic blood pressure from baseline (Day 1) to Week 26.

    Measured: Day 1, Week 26

  8. Change in Fasting Total Cholesterol From Baseline to Week 26

    Measured: Day 1, Week 26

  9. Change in Fasting High-density Lipoprotein (HDL) From Baseline to Week 26

    Change in fasting HDL from baseline (Day 1) to Week 26.

    Measured: Day 1, Week 26

  10. Ratio of Fasting Triglycerides at Week 26 to Baseline

    Ratio of triglycerides (measured in mg/dL) at Week 26 to baseline (Day 1). Log (Postbaseline Triglycerides) - log (Baseline Triglycerides); change from baseline to endpoint is presented as ratio of endpoint to baseline.

    Measured: Day 1, Week 26

  11. Assessment on Event Rate of Treatment-emergent Hypoglycemic Events

    Major hypoglycemia: events that, in the judgment of the investigator or physician, resulted in loss of consciousness, seizure, coma, or other change in mental status consistent with neuroglycopenia, in which symptoms resolved after administration of intramuscular glucagon or intravenous glucose, required third-party assistance, and was accompanied by a blood glucose concentration < 54 mg/dL prior to treatment. Minor hypoglycemia: symptoms consistent with hypoglycemia and blood glucose concentration < 54 mg/dL prior to treatment and not classified as major hypoglycemia.

    Measured: Day 1 to Week 26

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing exenatide once weekly, sitagliptin and pioglitazone in people with Type 2 Diabetes Mellitus, run by AstraZeneca at 62 sites in 3 countries.

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 12 inclusion and 10 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 7 Apr 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 62 sites in United States, Mexico, India. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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 19 Jun 2012). 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 HbA1c From Baseline to Week 26 (time frame: Day 1, Week 26). 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 NCT00637273, which also lists 8 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 7 Apr 2015.
