About this study

Official title: Effects of Sucralose on Insulin Sensitivity, Pancreatic Response and Appetite Regulating Hormones

In this study the effects of sucralose on insulin sensitivity, beta-cell response and appetite regulating hormones will be evaluated.

Read the detailed description

The consumption of non-nutritive sweeteners has a high prevalence. The effect of non-nutritive sweeteners in both beta-cell function and insulin resistance it is unknown.

Previous studies performed in animal models and humans with diverse characteristics have shown variable effects of different non-nutritive sweeteners in variables related to glucose metabolism.

Due to the high consumption of non-nutritive sweeteners it is relevant to know its effect in beta cell-function and insulin sensitivity.

In this study the effects of sucralose, a non-nutritive sweetener that is highly consumed in the population, on insulin sensitivity and beta-cell function will be evaluated.

54 participants with normal glucose tolerance, normal weight, and without chronic diseases with a low consumption of non-nutritive sweeteners will be included. The participants will be randomly assigned to consume sucralose or to a control group.

During the first visit an oral glucose tolerance test with 75 g of glucose will be performed. Fasting and 2-hour glucose will be measured in order to rule-out diabetes, abnormal fasting glucose, or glucose intolerance.

During the second visit a three-hour IV glucose tolerance test will be performed administering 0.3 g/kg of glucose and insulin 0.03 U/kg. Samples will be taken following the minimal model described by Bergman.

After this visit, the group assigned to receive sucralose will ingest 15% of the adequate daily intake (ADI) of sucralose and the control group will abstain of any non-nutritive sweetener consumption during 14 days. At the end of this period a third visit to repeat the IV glucose tolerance test will be performed.

Samples will be analyzed measuring glucose and insulin concentrations to evaluate acute insulin response (AIR), glucose effectiveness (SG), first phase pancreatic response (ф1), and second phase pancreatic response (ф2). In addition, hormones involved in appetite and satiety (leptin, ghrelin, and peptide tyrosine tyrosine) will be quantified at the beginning and end of the intervention.

  2. Ghrelin change

    Change in fasting ghrelin after sucralose ingestion

    Measured: Two weeks

  3. Tyrosine-tyrosine peptide (PYY) change

    Change in fasting PYY after sucralose ingestion

    Measured: Two weeks

  4. Leptin change

    Change in fasting leptin after sucralose ingestion

    Measured: Two weeks

Questions about this trial

What is this clinical trial studying?

A study testing Sucralose in people with Glucose Metabolism Disorders, run by Instituto Nacional de Ciencias Medicas y Nutricion Salvador Zubiran at 1 site in Mexico.

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 6 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 13 Nov 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 Mexico. 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 sensitivity (time frame: Two weeks). 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 NCT02589002, which also lists 4 linked publications.

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 13 Nov 2017.
