About this study
Specific Aims \& Hypothesis Primary Aim: To evaluate laparoscopic bariatric surgery versus intensive medical weight management on indices of insulin resistance and resolution of type 2 diabetes among patients with BMI 30-35.
Hypothesis: Bariatric surgery is the most effective treatment to induce diabetes remission in obese diabetic patients BMI 30-35.
The primary outcomes will be assessed at 6 months: (1) within-patient change in insulin resistance after either bariatric surgery or initiation of intensive medical weight management, and (2) remission of diabetes, (i.e., fasting glucose <126mg/dL and glucose <200mg/dL two hours after a standard 75g oral glucose load without the use of anti-hyperglycemic medications). Insulin resistance will be assessed at randomization and at 6 months with the homeostatic model assessment of insulin resistance (HOMA IR) based on insulin and fasting glucose, as well as oral glucose tolerance tests with area-under-the-curve (AUC) measurement for insulin values. Medication discontinuation will be derived from electronic health records and patient self-report at 6 months. Secondary outcomes will include changes in HBA1c, weight, blood pressure, waist circumference, and levels of fasting lipids.

What is being measured
The primary outcome is the main question the study is designed to answer.
Insulin Resistance
Within-patient change in insulin resistance after either bariatric surgery or initiation of intensive medical weight management, and remission of diabetes, (i.e., fasting glucose <126mg/dL and glucose <200mg/dL two hours after a standard 75g oral glucose load without the use of anti-hyperglycemic medications). Insulin resistance will be assessed at randomization and at 6 months with the homeostatic model assessment of insulin resistance (HOMA IR) based on insulin and fasting glucose, as well as oral glucose tolerance tests with area-under-the-curve (AUC) measurement for insulin values.
Measured: 6 months

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 1 inclusion and 1 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 1 Apr 2014. 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 United States. 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.
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?
Insulin Resistance (time frame: 6 months). 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 NCT01423877, 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 1 Apr 2014.
