What is being measured

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

  1. Median Percent Change From Baseline to Week 6 in LDL-c in FDC and RSG Monotherapy

    Median percent change from Baseline to Week 6 in LDL-c in FDC and RSG monotherapy was reported. Percent change from Baseline = 100*(exponent [change on log scale]-1). Baseline assessments were recorded at Visit 3 (Week 0). For a missing Baseline value, the Baseline value were replaced by the last pre-treatment measurement, if available. The hypothesis of treatment difference was tested at a 0.05 significance level based on two-sided tests. The point estimates and corresponding 95% confidence intervals for treatment differences was calculated. Treatment differences were assessed within the context of an analysis of covariance (ANCOVA) with terms for treatment, gender, current sulfonylurea use (at baseline), country, and Baseline measurement. ANCOVA for LDL-c were performed based on log-transformed data.

    Measured: Baseline (Week 0) and Week 6

Secondary outcomes (12)
  1. Mean Change From Baseline to Week 16 in Glycosylated Hemoglobin A1c (HbA1c) in FDC and SIMV Monotherapy

    Mean change from Baseline to Week 16 in HbA1c in FDC and SIMV monotherapy was reported. Change from Baseline was computed as (Visit value - Baseline value). Baseline assessments were recorded at Visit 3 (Week 0). For a missing Baseline value, the Baseline value were replaced by the last pre-treatment measurement, if available. The hypothesis of treatment difference was tested at a 0.05 significance level based on two-sided tests. The point estimates and corresponding 95% confidence intervals for treatment differences was calculated. Treatment differences were assessed within the context of ANCOVA with terms for treatment, gender, current sulfonylurea use (at Baseline), country, and Baseline measurement.

    Measured: Baseline (Week 0) and Week 16

  2. Median Percent Change From Baseline to Week 6 in LDL-c

    Percent change from Baseline = 100*(exponent [change on log scale]-1). Baseline assessments were recorded at Visit 3 (Week 0). For a missing Baseline value, the Baseline value were replaced by the last pre-treatment measurement, if available.

    Measured: Baseline (Week 0) and Week 6

  3. Mean Change From Baseline to Week 16 in HbA1c

    Change from Baseline was computed as (Visit value - Baseline value). Baseline assessments were recorded at Visit 3 (Week 0). For a missing Baseline value, the Baseline value were replaced by the last pre-treatment measurement, if available.

    Measured: Baseline (Week 0) and Week 16

  4. Mean Change From Baseline to Week 16 in Fasting Plasma Glucose (FPG)

    Change from Baseline was computed as (Visit value - Baseline value). Baseline assessments were recorded at Visit 3 (Week 0). For a missing Baseline value, the Baseline value were replaced by the last pre-treatment measurement, if available.

    Measured: Baseline (Week 0) and Week 16

  5. Number of Participant With LDL<100 mg/dL (2.59 mmol/L) at Week 6

    Number of participants achieving American Diabetes Association (ADA) target of LDL<100 mg/dL (2.59 mmol/L) at Week 6 was compared between the FDC groups and the all SIMV group using logistic regression with terms for treatment, Baseline value, gender and current sulfonylurea use (at Baseline) in the model.

    Measured: Week 6

  6. Number of Participants With HbA1c < 7.0% or Reduction of HbA1c ≥ 0.7% at Week 16

    Number of participants achieving ADA target of HbA1c < 7.0% or reduction of HbA1c ≥ 0.7% at Week 16 was compared between the FDC groups and the RSG groups groups using logistic regression with terms for treatment, Baseline value, gender and current sulfonylurea use (at Baseline) in the model.

    Measured: Up to Week 16

  7. Number of Participants With FPG< 126 mg/dL (7.0 mmol/L) or Reduction of FPG ≥ 30 mg/dL (1.67 mmol/L) at Week 16

    Number of participants achieving ADA target of FPG< 126 mg/dL (7.0 mmol/L) or reduction of FPG ≥ 30 mg/dL (1.67 mmol/L) at Week 16 was compared between the all SIM monotherapy group and the all FDC RSG/SIMV groups using logistic regression with terms for treatment, Baseline value, gender and current sulfonylurea use (at Baseline) in the model.

    Measured: Week 16

  8. On-Therapy Vital Signs of Potential Clinical Concern Including Systolic, Diastolic Blood Pressure and Heart Rate

    The potential clinical importance ranges (low and high) of the vital sign parameters were for systolic blood pressure (<85 and >160 millimeter of mercury [mmHg]), diastolic blood pressure (<45 and >100 mmHg) and heart rate (<40 and >110 beats per minute). Only those parameters for which at least one value of potential clinical importance was reported are summarized. The number of participants with potential clinical important vital parameter findings at any visit were reported.

    Measured: Up to Week 16

  9. On-Therapy Change From Baseline in Body Weight

    Baseline assessments were recorded at Visit 3 (Week 0). For a missing Baseline value, the Baseline value were replaced by the last pre-treatment measurement, if available. Change from Baseline was computed as: Visit value - Baseline Value.

    Measured: Up to Week 16

  10. Number of Participants With Specified Ranges of Red and White Blood Cell Counts Detected in Urine

    Urine samples were observed for red blood cells and white blood cells. the results were reported as cells per high-power field (cells/HPF). The number of participants with cells in urine were reported.

    Measured: Up to Week 16

  11. Number of Participants With Any Adverse Event (AE) and Serious Adverse Event (SAE)

    AE was defined as any untoward medical occurrence in a participant temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. SAE include AEs those result in death, a life-threatening AE, inpatient hospitalization or prolongation of existing hospitalization, a persistent or significant incapacity or substantial disruption of the ability to conduct normal functions, or a congenital anomaly/birth defect. Important medical events that may not result in death, be life-threatening, or require hospitalization may be considered serious when, based upon appropriate medical judgment, they may jeopardize the participant and may require medical or surgical intervention to prevent one of the outcomes listed in this definition.

    Measured: Up to Week 16

  12. Number of of Participants With Laboratory Evaluations of Potential Clinical Concern at Any Time Post-baseline

    The clinical chemistry parameters analyzed were sodium, potassium, bicarbonate, chloride, calcium, total protein, albumin, creatinine total bilirubin, blood urea nitrogen, alanine aminotransferase, aspartate aminotransferase, gamma-glutamyl transpeptidase, and alkaline phosphatase. The hematology parameters analyzed were hemoglobin, hematocrit, platelet count, total white cell count. Only those parameters for which at least one value of potential clinical importance was reported are summarized. The number of participants with potential clinical important hematology findings at any visit were reported.

    Measured: Up to Week 16

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing GSK523338 in people with Diabetes Mellitus, Type 2, run by GlaxoSmithKline at 85 sites in 6 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 3 inclusion and 3 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 2 Jul 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 85 sites in United States, Canada, Australia, Mexico, Philippines and 1 more country. 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 23 Mar 2018). 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?

Median Percent Change From Baseline to Week 6 in LDL-c in FDC and RSG Monotherapy (time frame: Baseline (Week 0) and Week 6). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 2 Jul 2018.
