Trial summary

This is a pilot study to show that it is possible to identify the specific types of fats in blood, adipose tissue, and liver tissue. The study doctors hope to use the analysis of these fats to learn more about nonalcoholic fatty liver disease (NFLD). Read more about this study

Key requirements

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 18 to 80 years
  • All sexes
  • Healthy volunteers accepted
  • Adult, Older adult

Who may be able to join

  • Subjects eligible to participate in the study will be:
  • Adults over age 18;
  • Patients enrolled in the bariatric surgery clinic who are planning to undergo and have insurance approval for bariatric surgery;
  • Insulin sensitive (based on HOMA-IR calculated from screening labs) OR insulin resistant (based on HOMA-IR and or personal history of diet controlled diabetes)
  • Able and willing to give informed consent.

Who cannot join

  • The following will exclude subjects from study participation:
  • Clinically significant medical issues outside of diabetes (eg, pregnancy, cardiovascular disease, uncontrolled pulmonary disease). If female and of child bearing potential, a pregnancy test will be performed and confirmed negative prior to participation in the study and prior to the scheduled glucose clamp procedure.
  • A history of hematologic (platelets <100 x107/L), hepatic (liver function tests [LFTs] >2X upper limit of normal), renal (Creatinine >1.5 mg/dL), pulmonary/ cardiac abnormalities (ie, abnormal electrocardiogram [EKG]).
  • Use of anti-diabetes medication, anticoagulants, or medication that might alter lipids. If the subject has a history of diabetes, it should be controlled by diet alone.
  • Inflammatory or celiac intestinal disease;
  • Untreated thyroid disease;
  • Excessive alcohol use, illicit drug use, or active untreated psychiatric disease.

About this study

This is a pilot study to show that it is possible to identify the specific types of fats in blood, adipose tissue, and liver tissue. The study doctors hope to use the analysis of these fats to learn more about nonalcoholic fatty liver disease (NFLD). Nonalcoholic fatty liver disease is the accumulation of fat in the liver of people who have minimal alcohol exposure. Nonalcoholic Fatty Liver Disease is associated with obesity and insulin resistance, and predicts development of Type 2 Diabetes. The study doctors are interested in looking at the relationship between liver fat and insulin resistance.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Hyperinsulinemic-euglycemic clampOther

    Also called glucose clamp

    Subject will received 6,6 2H2 Glucose prior and during a 4 hr hyperinsulinemic-euglycemic clamp to characterize hepatic insulin resistance prior to bariatric surgery

Study groupRoleWhat they receive
Measurement of insulin sensitivityOtherAll participants will undergo a hyperinsulinemic-euglycemic clamp to measure insulin sensitivity
Receives: Other: Hyperinsulinemic-euglycemic clamp

What is being measured

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

  1. Insulin Sensitivity

    Measured: Baseline

  2. Insulin Sensitivity

    Insulin sensitivity was assessed during the euglycemic/hyperglycemic clamp test. Insulin-mediated glucose uptake (M-value) was calculated as the mean glucose requirement during the 150-180 minute interval of the clamp

    Measured: 1 month

Questions about this trial

What is this clinical trial studying?

A study testing Hyperinsulinemic-euglycemic clamp in people with Type 2 Diabetes and Obesity, run by University of Minnesota at 1 site in United States.

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 5 inclusion and 7 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 20 Apr 2017. 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?

Yes. Results are posted in the registry (first posted 16 Jun 2015). 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?

Insulin Sensitivity (time frame: Baseline). 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?
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 Apr 2017.
