What is being measured

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

  1. Mean Change From Baseline at Week 16 (95% Confidence Interval) in Glycosated Hemoglobin A1c (HbA1c) (Last Observation Carried Forward) - Full Analysis Set (FAS)

    Baseline for HbA1c is defined as that value obtained at screening visit. HbA1c was measured as a percent (%) of hemoglobin; normal range was 4.7 to 6.4% and values were obtained through a central laboratory. The Last Observation Carried Forward (LOCF) data set includes data recorded at a given visit or, if no observation is recorded at that visit, data carried forward from the previous visit.

    Measured: Baseline to Week 16

Secondary outcomes (8)
  1. Mean Change From Baseline at Week 16 (95% Confidence Interval) of Fasting Plasma Glucose (FPG) - Full Analysis Set

    Baseline was defined as the value obtained at the screening visit. FPG was measured in millimoles/Liter (mmol/L) and obtained through local laboratories.

    Measured: Baseline to Week 16

  2. Mean Change From Baseline at Week 16 (95% Confidence Interval) in Fasting Total Cholesterol (TC) - Full Analysis Set

    For fasting total cholesterol (TC), baseline is defined as Day 1 (first day of treatment). Total cholesterol was measured in millimoles per liter (mmol/L) and obtained through local laboratories.

    Measured: Baseline to Week 16

  3. Mean Change From Baseline at Week 16 (95% Confidence Interval) in Fasting Low-density Lipoprotein Cholesterol (LDL-C) - Full Analysis Set

    Baseline was defined as values obtained on Day 1. Low-density lipoprotein cholesterol (LDL-C) was measured in millimoles per liter (mmol/L) and obtained through local laboratories.

    Measured: Baseline to Week 16

  4. Mean Change From Baseline at Week 16 (95% Confidence Interval) in Fasting High-density Lipoprotein Cholesterol (HDL-C) - Full Analysis Set

    Baseline was defined as value obtained on Day 1 (first day of treatment). High-density lipoprotein cholesterol (HDL-C) was measured in millimoles per liter (mmol/L) and obtained through local laboratories.

    Measured: Baseline to Week 16

  5. Mean Change From Baseline at Week 16 (95% Confidence Interval) in Fasting Triglycerides (TG) - Full Analysis Set

    Baseline was defined as value obtained on Day 1 (first day of treatment). Triglycerides (TG) were measured in millimoles per liter (mmol/L)and values obtained through local laboratories.

    Measured: Baseline to Week 16

  6. Mean Change From Baseline at Week 16 (95% Confidence Interval) in C-Reactive Protein (CRP) - Full Analysis Set

    Baseline was defined as value obtained on Day 1 (first day of treatment). C-Reactive Protein (CRP) was measured in milligrams/liter (mg/L) and values were obtained through a central laboratory; normal was less than 5.0 mg/L.

    Measured: Baseline to Week 16

  7. Mean Change From Baseline at Week 16 (95% Confidence Interval) in Plasminogen Activator Inhibitor-1 (PAI-1) - Full Analysis Set

    Baseline was defined as value obtained on Day 1 (first day of treatment). PAI-1 (activity) was measured in units/milliliter (U/mL)and values obtained through a central laboratory; normal was less than 25.00 U/mL.

    Measured: Baseline to Week 16

  8. Mean Change From Baseline at Week 16 (95% Confidence Interval) in Adiponectin - Full Analysis Set

    Baseline was defined as value obtained on Day 1 (first day of treatment). Adiponectin was measured in milligrams/liter (mg/L) and values obtained through a central laboratory; normal range was 1.20 to 20.00 mg/L.

    Measured: Baseline to Week 16

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Metformin XR in people with Type 2 Diabetes Mellitus, run by Bristol-Myers Squibb at 14 sites in China.

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 5 inclusion and 20 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 Aug 2013. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 14 sites in China. 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 20 Aug 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?

Mean Change From Baseline at Week 16 (95% Confidence Interval) in Glycosated Hemoglobin A1c (HbA1c) (Last Observation Carried Forward) - Full Analysis Set (FAS) (time frame: Baseline to Week 16). 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 NCT00778622, which also lists 1 linked publication.

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 Aug 2013.
