About this study

Official title: Development of a Fast Measurement Technique of Insulin Resistance in Human, With 123-6-deoxy-6 Iodo-D-glucose, a New Tracer of Glucose Transport

Insulin resistance, characterised by a depressed cellular sensitivity to insulin in insulin-sensitive organs, is a central feature of the metabolic syndrome. In people with no diabetes mellitus, the presence of metabolic syndrome leads to an increase of mortality, whatever the cause, but, as a majority, cardiovascular diseases.

In patients with type 2 diabetes mellitus, the presence of a metabolic syndrome leads to an increase in major adverse cardiovascular events. The prevalence of metabolic syndrome is led to grow in a near future, because of the increase of diabetes mellitus and obesity prevalence.

Actually, there is no simple tool to measure insulin resistance. The gold standard technique remains the hyperinsulinemic euglycemic clamp. However, the complexity and length of this technique render it unsuitable for routine clinical use. Many methods or index have been proposed to assess insulin resistance in human, but none have shown enough relevance to be used in clinical use.

Within the investigators U877 INSERM team, the investigators previously performed in vivo biodistribution studies with 6-DIG (6-deoxy-6-iodo-D-glucose), a new tracer of glucose transport, radiolabelled with123 iodine, with and without insulin, on the one hand in genetically diabetic mice (db/db), consequently having a severe insulin resistance and in the other hand in rats with acquired insulin resistance after a "fructose diet".

The investigators have demonstrated that 6-DIG is able to identify in vivo slight glucose transport variations in insulin sensible organs. Then, the investigators developed a fast and simple imaging protocol with a small animal gamma camera, which allows the obtaining of an insulin resistance index for each organ, directly transferable to human.

The investigators project is to transfer to human this measurement technique, perfectly validated in animal.

The main goal of this monocentric phase I-II study is to evaluate the tolerance to the insulin resistance measurement technique with 6DIG scintigraphy, in healthy volunteers and in diabetic patients. The investigators plan to enrol 6 healthy volunteers and 6 type 2 diabetic patients.

The investigators secondary goals will be to evaluate feasibility and reproducibility of the measurement technique, to follow pharmacokinetic and to assess efficacy of 6-DIG to measure insulin resistance.

What is being measured

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

  1. Change of glycemia

    Assessment of tolerance to insulin resistance measurement technique with 6-DIG scintigraphy, in healthy volunteers

    • clinical tolerance to 6-DIG infusion
    • clinical and biological tolerance to insulin infusion
    • evaluation of dosimetry

    Measured: Before inclusion in clinical trial, Before radiotracer injection, After radiotracer injection (time: 30s, 1', 2',5',10',15',25', 1 hour, 2 hours, 4 hours, 8 hours, 24 hours)

Secondary outcomes (4)
  1. insulinemia

    Measured: Before inclusion in clinical trial, Before radiotracer injection, After radiotracer injection (time: 30s, 1', 2',5',10',15',25', 1 hour, 2 hours, 4 hours, 8 hours, 24 hours)

  2. clinical side effects

    hypoglycemia symptoms

    Measured: Before inclusion in clinical trial, Before radiotracer injection, After radiotracer injection (time: 30s, 1', 2',5',10',15',25', 1 hour, 2 hours, 4 hours, 8 hours, 24 hours)

  3. dosimetry

    organs biodistribution of radioactivity

    Measured: during the 24 hours following injection of 6-DIG

  4. insulin resistance

    scintigraphic measurement of glucose transport in heart before and after infusion of insulin

    Measured: 0-15 minutes following 6-DIG infusion

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing injection of 6-DIG in people with Type 2 Diabetes Mellitus, run by Institut National de la Santé Et de la Recherche Médicale, France at 1 site in France.

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 20 inclusion and 26 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 27 Aug 2025. 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 France. 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 combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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?

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?

Change of glycemia (time frame: Before inclusion in clinical trial, Before radiotracer injection, After radiotracer injection (time: 30s, 1', 2',5',10',15',25', 1 hour, 2 hours, 4 hours, 8 hours, 24 hours)). 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 NCT01493934, 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 27 Aug 2025.
