What is being measured
The primary outcome is the main question the study is designed to answer.
Mean Change From Baseline in Hemoglobin A1c (Glycosylated Hemoglobin) (HbA1c) at Week 12
The blood samples were collected at Baseline, Week 4, Week 8 and at Week 12 (or early withdrawal). Baseline was defined as the period immediately preceding treatment with study medication (Week 0). For participants with missing Baseline assessment, the last pre-therapy value prior to the Baseline visit was used as the Baseline value. Change from Baseline was the value at Week 12 minus Baseline value. The primary analysis was performed on the Intent-to-Treat (ITT) Population with Last observation carried forward (LOCF). Adjusted mean is presented as least square (LS) mean.

Differences between treatment groups in the proportion of participants who achieved HbA1c targets of <=6.5% and <7% at Week 12 in the ITT population with LOCF were assessed based on a logistic regression model with terms included for treatment and Baseline HbA1c. Differences between treatment groups in the proportion of participants who achieved a clinically meaningful decreases from Baseline in HbA1c (>=0.7%) at Week 12 were assessed in the same manner.
Measured: Week 12
Number of Participants Who Were Fasting Plasma Glucose (FPG) Responders at Week 12
Differences between treatment groups in the proportion of participants who achieved FPG targets of <7.0 millimoles per liter (mmol/L) (126 milligrams per deciliter [mg/dL]) and <7.8 mmol/L (140 mg/dL) at Week 12 in the ITT population with LOCF were assessed based on a logistic regression model with terms included for treatment and Baseline FPG. The proportion of participants who achieved the target of <5.5 mmol/L (100 mg/dL) at Week 12 within each treatment group were summarized only. Differences between treatment groups in the proportion of participants who achieved a clinically meaningful decreases from Baseline in FPG (1.7 mmol/L [>=30 mg/dL]) at Week 12 were assessed in the same manner.
Measured: Week 12
Mean Change From Baseline to Week 12 in Triglycerides
Samples were collected at Baseline and at Week 12 (or early withdrawal). Baseline was defined as the period immediately preceding treatment with study medication (Week 0). For participants with missing Baseline assessment, the last pre-therapy value prior to the Baseline visit was used as the Baseline value. Change from Baseline was the value at Week 12 minus Baseline value. Adjusted mean is presented as LS mean.
Measured: Baseline (Week 0) and at Week 12
Mean Change From Baseline to Week 12 in Total Cholesterol
Samples were collected at Baseline and at Week 12 (or early withdrawal). Baseline was defined as the period immediately preceding treatment with study medication (Week 0). For participants with missing Baseline assessment, the last pre-therapy value prior to the Baseline visit was used as the Baseline value. Change from Baseline was the value at Week 12 minus Baseline value. Adjusted mean is presented as LS mean.
Measured: Baseline (Week 0) and at Week 12
Mean Change From Baseline to Week 12 in Low Density Lipoprotein Cholesterol (LDL-c)
Blood samples were collected at Baseline and at Week 12 (or early withdrawal). Baseline was defined as the period immediately preceding treatment with study medication (Week 0).

Full 12-lead ECGs were recorded at Randomization (Week 0), Week 4, and Week 12 or early withdrawal. If the QTc was >500 milliseconds on the locally read ECG recording, an additional 2 ECG recordings at 10 minute intervals were made at that visit. If the average QTc for the 3 recordings was >500 milliseconds, the participant was withdrawn from the study.
Measured: Up to Week 12
Number of Participants With Abnormal Chemistry Value of PCI at Any Time on Therapy
Chemistry parameters: Albumin, Alkaline phosphatase, Alanine animotransferase, Aspartate aminotransferase, Total billirubin, Calcium, Carbon dioxide/Bicarbonate, Glucose, Potassium, Sodium, Phosphorus and Total protein were assessed for abnormal PCI values. Participants were instructed to fast for at least 8 hours prior to all study visits for the collection of laboratory samples. Samples were collected at Baseline, Week 2, Week 4, Week 8, Week 12 and at Week 14 (follow up).
Measured: Up to Week 12
Number of Participants With Abnormal Hematology Value of PCI at Any Time on Therapy
Hematology parameters: Hemoglobin, Hematocrit, Platelet count and White blood cells were assessed for abnormal PCI values. Participants were instructed to fast for at least 8 hours prior to all study visits for the collection of laboratory samples. Samples were collected at Baseline, Week 2, Week 4, Week 8, Week 12 and at Week 14 (follow up).
Measured: Up to Week 12

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
This is a dose-ranging study to evaluate the efficacy, safety and tolerability of a range of doses of GSK189075 (an SGLT2 inhibitor) compared to placebo, administered over 12 weeks in treatment-naive subjects with type 2 diabetes mellitus

Primary outcome
Mean Change From Baseline in Hemoglobin A1c (Glycosylated Hemoglobin) (HbA1c) at Week 12
Time frame: Baseline (Week 0) and at Week 12
The blood samples were collected at Baseline, Week 4, Week 8 and at Week 12 (or early withdrawal). Baseline was defined as the period immediately preceding treatment with study medication (Week 0). For participants with missing Baseline assessment, the last pre-therapy value prior to the Baseline visit was used as the Baseline value. Change from Baseline was the value at Week 12 minus Baseline value. The primary analysis was performed on the Intent-to-Treat (ITT) Population with Last observation carried forward (LOCF). Adjusted mean is presented as least square (LS) mean.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing GSK189075 in people with Diabetes Mellitus, Type 2, run by GlaxoSmithKline at 157 sites in 16 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 10 inclusion and 63 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 30 Oct 2017. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 157 sites in United States, Germany, Canada, Puerto Rico, India and 11 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
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 30 Oct 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?
Mean Change From Baseline in Hemoglobin A1c (Glycosylated Hemoglobin) (HbA1c) at Week 12 (time frame: Baseline (Week 0) and at Week 12). 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 NCT00495469, 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 30 Oct 2017.
