Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.
- Ages 30 to 65 years
- All sexes
- No healthy volunteers
- Adult, Older adult
Who may be able to join
- BMI 27-36 kg/m2 inclusive and at least two additional features of the metabolic syndrome or a first degree relative with a history of type 2 diabetes mellitus. BMI = Weight/height², (where weight is in kg, height in m).
- Male or female aged 30 to 65 years, inclusive, at screening.
- Female subjects must be post-menopausal (i.e. >6 months without menstrual period), surgically sterile, or using effective contraceptive measures (oral contraceptives, Norplant Depo-Provera) or intra-uterine devices (IUD) (a diaphragm with spermicide or a condom with spermicide). Women of childbearing potential must use effective contraceptive measures for at least 1 month prior to visit 1, and should continue to use the same contraceptive method during the study and for 30 days after discontinuing study treatment.
- Willing and able to provide a signed and dated written informed consent.
Who cannot join
- Subjects with type 2 diabetes mellitus defined as an HbA1c level >6.5% or a fasting plasma glucose of > 7.0 mmol/L. If fasting plasma glucose is between 6.1 and 7.0 mmol/L then a 75 g oral glucose test will be performed to exclude diabetes mellitus.
- Subjects who have initiated lipid lowering therapy within the last 6 months and subjects who have increased the dose of these therapies within the last 3 months prior to study start.
- Subjects who are taking Non Steroidal Anti-inflammatory Drugs, fibrates, anticoagulants or cardiovascular medications (β-blockers, nitrates, calcium antagonists, ACE inhibitors, angiotensin II antagonists, alpha blockers, diuretics, centrally acting anti-hypertensives, directly acting antihypertensives e.g., diazoxide, digoxin, anti-arrhythmics) and are unable to stop these medications for the duration of the study.
- Exposure to a thiazolidinedione (TZD) or other PPAR-γ agonist (e.g. rosiglitazone, troglitazone, pioglitazone, G1262570) within the last 4 months or participation in a clinical study involving a TZD or PPAR-γ agonist.
- Subjects who have required the use of any anti-diabetic medication at any time.
- Use of any investigational drug within 30 days preceding the first dose of medication at the start of the study.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Avandia in people with Insulin Resistance, run by GlaxoSmithKline at 1 site in Netherlands.
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 14 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 5 Dec 2016. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Netherlands. 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?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
Forearm blood flow. 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 5 Dec 2016.
