What is being measured

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

  1. Adjusted Mean Change From Baseline in Hemoglobin A1C (HbA1c) at Week 24 (Last Observation Carried Forward [LOCF])

    HbA1c was measured as percent of hemoglobin by a central laboratory. Data after rescue medication was excluded from this analysis. Baseline was defined as the last assessment prior to the start date and time of the first dose of the double-blind study medication. In cases where time of the first dose or time of the assessment was not available, baseline was defined as the last assessment on or prior to the date of the first dose of the double-blind study medication. HbA1c measurements were obtained during the qualification and lead-in periods and on Day 1 and Weeks 4, 8, 12, 16, 20, and 24 in the double-blind period.

    Measured: From Baseline to Week 24

Secondary outcomes (6)

  1. Adjusted Mean Change From Baseline in 120-minute Post-challenge Plasma Glucose (PPG) (mg/dL) at Week 24 (Last Observation Carried Forward [LOCF])

    Secondary endpoints were tested using sequential testing procedure and are presented in hierarchical order. In post oral glucose tolerance test (OGTT), glucose was measured as milligrams per deciliter(mg/dL) by a central laboratory. Baseline was defined as the last assessment prior to the start date and time of the first dose of the double-blind study medication. In cases where time of the first dose or time of the assessment was not available, baseline was defined as the last assessment on or prior to the date of the first dose of the double-blind study medication. PPG measurements were obtained on Day 1 and week 24 in the double-blind period.

    Measured: From Baseline to Week 24

  2. Adjusted Mean Change From Baseline in Total Body Weight (kg) at Week 24 (Last Observation Carried Forward [LOCF])

    Secondary endpoints were tested using sequential testing procedure and are presented in hierarchical order. Adjusted mean change from baseline in total body weight at Week 24 (or the last postbaseline measurement prior to Week 24 if no Week 24 assessment was available was determined. Data after rescue medication was excluded from this analysis. Baseline was defined as the last assessment prior to the start date and time of the first dose of the double-blind study medication. In cases where time of the first dose or time of the assessment was not available, baseline was defined as the last assessment on or prior to the date of the first dose of the double-blind study medication. Body weight measurements were obtained during the qualification and lead-in periods and on Day 1 and Weeks 1, 2, 4, 8, 12, 16, 20, and 24 of the double-blind period.

    Measured: From Baseline to Week 24

  3. Adjusted Mean Change From Baseline in Fasting Plasma Glucose (FPG) at Week 24 (Last Observation Carried Forward [LOCF])

    Secondary endpoints were tested using sequential testing procedure and are presented in hierarchical order. Fasting plasma glucose was measured as milligrams per deciliter(mg/dL) by a central laboratory. Baseline was defined as the last assessment prior to the start date and time of the first dose of the double-blind study medication. In cases where time of the first dose or time of the assessment was not available, baseline was defined as the last assessment on or prior to the date of the first dose of the double-blind study medication. FPG measurements were obtained during the qualification and lead-in periods and on Day 1 and Weeks 1, 2, 4, 8, 12, 16, 20, and 24 in the double-blind period.

    Measured: From Baseline to Week 24

  4. Percentage of Participants Achieving a Therapeutic Glycemic Response (Hemoglobin A1c [HbA1C]) <7.0% at Week 24 (Last Observation Carried Forward [LOCF])

    Secondary endpoints were tested using sequential testing procedure and are presented in hierarchical order. Percent adjusted for baseline HbA1c. Therapeutic glycemic response is defined as HbA1c <7.0%. Data after rescue medication was excluded from this analysis. HbA1c was measured as a percent of hemoglobin. Mean and standard error for percentage of participants were estimated by modified logistic regression model.

    Measured: From Baseline to Week 24

  5. Adjusted Mean Change From Baseline in Waist Circumference (cm) at Week 24 (Last Observation Carried Forward [LOCF])

    Secondary endpoints were tested using sequential testing procedure and are presented in hierarchical order. Adjusted mean change from baseline in waist circumference at Week 24 (or the last postbaseline measurement prior to Week 24 if no Week 24 assessment was available was determined. Data after rescue medication was excluded from this analysis. Baseline was defined as the last assessment prior to the start date and time of the first dose of the double-blind study medication. In cases where time of the first dose or time of the assessment was not available, baseline was defined as the last assessment on or prior to the date of the first dose of the double-blind study medication. Waist circumference measurements were obtained during the qualification and lead-in periods and on Day 1 and Week 24 of the double-blind period.

    Measured: From Baseline to Week 24

  6. Adjusted Mean Change From Baseline in Total Body Weight (kg) Among Subjects With Baseline Body Mass Index (BMI) ≥ 27 kg/m^2 at Week 24 (Last Observation Carried Forward [LOCF])

    Secondary endpoints were tested using sequential testing procedure and are presented in hierarchical order. Adjusted mean change from baseline in total body weight among subjects with baseline body mass index (BMI) ≥ 27 kg/m^2 at Week 24 (or the last postbaseline measurement prior to Week 24 if no Week 24 assessment was available was determined. Data after rescue medication was excluded from this analysis. Baseline was defined as the last assessment prior to the start date and time of the first dose of the double-blind study medication. In cases where time of the first dose or time of the assessment was not available, baseline was defined as the last assessment on or prior to the date of the first dose of the double-blind study medication. Body weight measurements were obtained during the qualification and lead-in periods and on Day 1 and Weeks 1, 2, 4, 8, 12, 16, 20, and 24 of the double-blind period.

    Measured: From Baseline to Week 24

A Phase 3 study testing Dapagliflozin and Thiazolidinedione (Pioglitazone) in people with Type 2 Diabetes, run by AstraZeneca at 89 sites in 9 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 4 inclusion and 7 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 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 89 sites in United States, Mexico, Canada, Argentina, India and 4 more countries. 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 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 23 Feb 2017). 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?

Adjusted Mean Change From Baseline in Hemoglobin A1C (HbA1c) at Week 24 (Last Observation Carried Forward [LOCF]) (time frame: From Baseline to Week 24). 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 NCT00683878, which also lists 4 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 23 Feb 2017; AzTrials last refreshed its copy on 7 Nov 2026.
