About this study

Official title: The Role of the Microbiome in Personalized Human Response to Non-caloric Sweeteners

Non-caloric sweeteners are common food supplements consumed by millions worldwide as means of combating weight gain and diabetes, by retaining sweet taste without increasing caloric intake. While they are considered safe, there is increasing debate regarding their potential role in contributing to metabolic derangements in some humans. The investigators recently demonstrated that non-caloric sweeteners consumption could induce glucose intolerance in mice and, in preliminary experiments, in distinct human subsets, by functionally altering the gut microbiome, and that the gut microbiome plays an important role in mediating differential glucose responses to identical foods. The proportion of the human population that is susceptible to glucose intolerance induced by non-caloric sweeteners, the common factors that are shared between these individuals and whether and how the microbiome promotes the metabolic derangements remain to be addressed.

  • AspartameDietary supplement

    Daily consumption of six commercially available sachets containing aspartame and glucose as bulking agent (1g each sachet), for 14 days.

  • SucraloseDietary supplement

    Daily consumption of six commercially available sachets containing sucralose and glucose as bulking agent (1g each sachet), for 14 days.

  • SaccharinDietary supplement

    Daily consumption of six commercially available sachets containing saccharine and glucose as bulking agent (1g each sachet), for 14 days.

  • SteviaDietary supplement

    Daily consumption of six commercially available sachets containing Stevia and glucose as bulking agent (1g each sachet), for 14 days.

  • No SupplementOther

    Follow up without any dietary supplementation.

Questions about this trial

What is this clinical trial studying?

A study testing Glucose, Aspartame and Sucralose in people with Glucose Intolerance and Glucose, Low Blood, run by Weizmann Institute of Science at 1 site in Israel.

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 4 Aug 2021. 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 Israel. 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?

Blood glucose level (time frame: 28 days). 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 4 Aug 2021.
