About this study

Official title: Effects of Oral Pre-loads on Subsequent Energy Intake, Gastrointestinal Hormones, Glycemic Control, Appetite-related Sensations, and Gastrointestinal Tolerance

The aim of this project is to investigate the effect of erythritol (given as pre-load), compared to sucrose, sucralose, and water on energy intake during a subsequent ad libitum test meal in healthy participants.

Furthermore, the release of GI hormones, glycemic control, appetite-related sensations, GI tolerance, sweetness and liking in response to the pre-loads will be investigated.

Read the detailed description

The subjects will participate in four study days. The screening will last 60 minutes, the study days about 4.5 hours each. After a simple-carbohydrate standard dinner, the subjects have to do an overnight fast until the next morning. Subjects will receive fixed equisweet doses of sucrose (33.5g), erythritol (50g), sucralose (0.0558g), or water as oral pre-loads in a blinded, randomized (counterbalanced) fashion (t = -15 min). Fifteen minutes after the administration (t = 0 min), a standard solid test meal will be presented and ad libitum calorie intake will be measured. The end of the test meal will be after 20 minutes or as soon as the subject stops eating for more than 5 minutes. Blood samples (to measure: glycemic control and GI hormones) will be collected at t = -16, t = -1, t = 15, t = 30, t = 60, t = 90, t = 120, t = 150, t = 180 min and appetite-related sensation rating will be collected at t = -16, t = -1, t = 15, t = 30, t = 60, t = 90, t = 120, t = 150, t = 180 min. GI symptoms and nausea are assessed at t = -16, -1, 30, 60, 120 and 180 min. At t = -10 min subjects are asked to rate the perceived sweetness and liking of the pre-load and at t = 180 min the perceived liking of the test meal.

  9. Effects on appetite-related sensations

    Appetite perceptions (feelings of: a) hunger, b) satiety) are assessed by visual analogue scale (VAS). Visual analogue scales consist of a horizontal, unstructured, 10-cm line representing the minimum (0.0 points) to the maximum rating (10.0 points). Subjects assign a vertical mark across the line to indicate the magnitude of their subjective sensation at the present time point. The measurement is quantified by the distance from the left end of the line (minimum rating) to the subject's vertical mark.

    Measured: Visual analogue scales will be recorded at the following time points: t = -16, t = -1 (before the administration of the pre-loads), t = 15, t = 30, t = 60, t = 90, t = 120, t = 150, t = 180 minutes (after the administration of the pre-loads).

  10. Effects on GI tolerance

    GI symptoms will be assessed by use of a checklist including the following questions: abdominal pain, nausea, vomiting, diarrhoea, borborygmi, abdominal distension, eructation and increased flatus.

    Measured: GI tolerance will be recorded at t = -16, -1 (before the administration of the pre-load), 30, 60, 120 and 180 minutes (after the administration of the pre-load).

  11. Sweetness of pre-load

    Sweetness is assessed by gLMS. General Labeled Magnitude Scales consist of an unequal, vertical line, which is marked with quasi-logarithmic verbal anchors describing different intensities (e.g. "strongest imaginable", "barely detectable"). Participants are instructed to place a mark on the line where their perceived intensity of sensation lies.

    Measured: Sweetness of the pre-load will be recorded at t = -10 minutes.

  12. Liking ot the pre-load

    Liking is assessed by gLMS. General Labeled Magnitude Scales consist of an unequal, vertical line, which is marked with quasi-logarithmic verbal anchors describing different intensities (e.g. "strongest imaginable", "barely detectable"). Participants are instructed to place a mark on the line where their perceived intensity of sensation lies.

    Measured: Liking of the pre-load will be recorded at t = -10 minutes.

  13. Liking of the test meal

    Liking is assessed by gLMS. General Labeled Magnitude Scales consist of an unequal, vertical line, which is marked with quasi-logarithmic verbal anchors describing different intensities (e.g. "strongest imaginable", "barely detectable"). Participants are instructed to place a mark on the line where their perceived intensity of sensation lies.

    Measured: Liking of the test meal will be recorded at t = 180 minutes.

Questions about this trial

What is this clinical trial studying?

A study testing Erythritol, Sucrose and Sucralose in people with Energy Intake and Gastrointestinal Hormones, run by University Hospital, Basel, Switzerland at 1 site in Switzerland.

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 8 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 16 Dec 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 Switzerland. 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. Some participants in this study may receive a placebo. 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?

Effect of erythritol on energy intake during a subsequent ad libitum test meal (time frame: Total energy intake will be measured from t = 0 until t = 20 minutes or as soon as the as the subject stops eating for more than 5 minutes.). 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 16 Dec 2021.
