What is being measured

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

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

    HbA1c was measured 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. If no Week 24 assessment was available, the last postbaseline measurement prior to Week 24 was used. For rescued participants, measurements obtained after initiation of rescue medication were not considered in calculating the primary endpoint. Evening dosing groups were summarized as exploratory endpoints.

    Measured: Baseline to Week 24 (end of Short-term Period)

  2. Adjusted Mean Change From Baseline to Week 24 in Hemoglobin A1c (HbA1c) (Last Observation Carried Forward [LOCF]): Group 2

    HbA1c was measured 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. If no Week 24 assessment was available, the last postbaseline measurement prior to Week 24 was used. For rescued participants, measurements obtained after initiation of rescue medication were not considered in calculating the primary endpoint. Group 2 (patients with enrollment baseline HbA1c >10% and ≤2%) was considered an exploratory group, included to obtain initial efficacy and safety data for these patients. No comparator arm was included.

    Measured: Baseline to Week 24 (end of Short-term Period)

Secondary outcomes (15)
  1. Adjusted Mean Change From Baseline to Week 24 in Fasting Plasma Glucose Levels (Last Observation Carried Forward [LOCF]): Group 1

    Secondary endpoints were tested using a sequential testing procedure and are presented in hierarchical order. Because the primary focus of the entire dapagliflozin program was on morning dosing in a population with HbA1c ≥7% and ≤10%, only data on AM dosing were summarized in secondary efficacy analyses. Data after rescue medication were 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. If no Week 24 assessment was available, glucose levels were recorded from the last postbaseline measurement prior to Week 24. For rescued participants, measurements obtained after initiation of rescue medication was not considered in calculating the endpoint.

    Measured: Baseline to Week 24 (end of Short-term Period)

  2. Adjusted Mean Change From Baseline to Week 24 in Fasting Plasma Glucose Levels (Last Observation Carried Forward [LOCF]): Group 2

    Group 2 was an exploratory group, included to obtain initial efficacy and safety data. No comparator arm was included. Secondary endpoints were tested using a sequential testing procedure and are presented in hierarchical order. Data after rescue medication were 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. If no Week 24 assessment was available, glucose levels were recorded from the last postbaseline measurement prior to Week 24. For rescued participants, measurements obtained after initiation of rescue medication was not considered in calculating the endpoint.

    Measured: Baseline to Week 24 (end of Short-term Period)

  3. Adjusted Mean Change in Total Body Weight at Week 24 (Last Observation Carried Forward [LOCF]): Group 1

    Secondary endpoints were tested using a sequential testing procedure and are presented in hierarchical order. Because the primary focus of the entire dapagliflozin program was on morning dosing in a population with HbA1c ≥7% and ≤10%, only data on AM dosing were summarized. 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.

    Measured: From Baseline to Week 24 (end of Short-term Period)

  4. Adjusted Mean Change in Total Body Weight at Week 24 (Last Observation Carried Forward [LOCF]): Group 2

    Secondary endpoints were tested using a 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.Group 2 (patients with enrollment baseline HbA1c >10% and ≤2%) was considered an exploratory group, included to obtain initial efficacy and safety data for these patients. No comparator arm was included.

    Measured: From Baseline to Week 24 (end of Short-term Period)

  5. Adjusted Mean Change From Baseline in Fasting Plasma Glucose Levels at Week 1 (Last Observation Carried Forward [LOCF]): Group 1

Data after rescue medication was excluded from this analysis. Fasting plasma glucose was measured 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.

    Measured: Baseline to Week 1 (end of Short-term Period)

  6. Adjusted Mean Change From Baseline in Fasting Plasma Glucose Levels at Week 1 (Last Observation Carried Forward [LOCF]): Group 2

Data after rescue medication was excluded from this analysis. Fasting plasma glucose was measured 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.

    Measured: Baseline to Week 1

  7. Adjusted 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 a sequential testing procedure and are presented in hierarchical order. Therapeutic glycemic response is defined as HbA1c <7.0%. Data after rescue medication was excluded from this analysis. If no Week 24 assessment was available, HbA1c was recorded from the last postbaseline measurement prior to Week 24. Group 2 (patients with enrollment baseline HbA1c >10% and ≤2%) was considered an exploratory group, included to obtain initial efficacy and safety data for these patients. No comparator arm was included. Thus, only key safety and efficacy analyses were performed for Group 2.

    Measured: Baseline to Week 24 (end of Short-term Period)

  8. Adjusted Mean Change From Baseline to Week 24 in Hemoglobin A1c (HbA1c) in Patients With Baseline HbA1c ≥9.0% (Last Observation Carried Forward [LOCF])

    Secondary endpoints were tested using a sequential testing procedure and are presented in hierarchical order. If no Week 24 assessment was available, HbA1c was recorded from the last postbaseline measurement prior to Week 24. HbA1c was measured as % of hemoglobin by a central laboratory. The population included randomized patients who received treatment and had baseline HbA1c >9.0%. Data after rescue medication were excluded from this analysis. Baseline was defined as the last assessment prior to the start date and time of the first dose of double-blind study drug. In cases where time of the first dose or 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 drug.

    12-Lead ECGs were performed at entry into lead-in period Day -7 visit and Week 24/end of treatment visit (LOCF) on participants who were supine. ECGs were assessed by the investigator. Baseline was Day -7 for this parameter, and data after rescue were included.The Week 102 value is the last observation, regardless of rescue prior to Week 102 if no Week 102 measurement was available. Group 2 (patients with enrollment baseline HbA1c >10% and ≤2%) was considered an exploratory group, included to obtain initial efficacy and safety data for these patients. No comparator arm was included. Thus, only key safety and efficacy analyses were performed for Group 2.

    Measured: Baseline to Week 24 (end of Short-term Period)

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 20 Oct 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 78 sites in United States, Canada, Mexico, Russia. 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 14 May 2014). 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 to Week 24 in Hemoglobin A1C (HbA1c) (Last Observation Carried Forward [LOCF]): Group 1 (time frame: Baseline to Week 24 (end of Short-term Period)). The study lists 2 primary outcomes in all. 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 NCT00528372, which also lists 5 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 20 Oct 2015.
