Study summary

This study investigates whether the gut hormone glucose-dependent insulinotropic polypeptide (GIP) can reduce feelings of nausea. GIP is naturally released after meals and is administered intravenously to healthy participants during the experiment. Nausea is induced using either glucagon-like peptide 1 (GLP-1), another gut hormone, or apomorphine, a medication known to trigger nausea. By combining these substances, the study aims to determine whether GIP can alleviate nausea. The findings may improve understanding of interactions between the gut and the brain.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Men or women, age of 18-60 years
  • between 19-27 kg/m2 (both included)

Exclusion criteria

Exclusion Criteria:

  • Current or past treatment with GLP-1 or GIP/GLP-1 receptor-targeting compounds within the last six months
  • Gastrointestinal disorders that the investigator evaluates could interfere with induction of nausea (e.g. gastroparesis, functional dyspepsia and GI surgery)
  • Neurological disorders affecting nausea (e.g. severe migraines and neuropathy)
  • Any known eating disorders (e.g. anorexia nervosa and bulimia)
  • Pregnancy or breastfeeding
  • (ALT) and/or aspartate aminotransferase (AST) (> 2 times normal values) or present hepatobiliary disease
  • Kidney disease (estimated (eGFR)\<90 ml/min/1.73 m2) at screening
  • Severe arteriosclerotic heart disease or heart failure ( class II-IV)
  • (HbA1c) ³ 48 mmol/mol and/or diagnosed type 1 or type 2 diabetes
  • Any condition that the investigator evaluates would interfere with study participation
Terms in these criteria, in plain language(6)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

BMI (body mass index)

Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.

What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

ALT and AST (liver enzymes)

Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.

Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.

GFR and eGFR (kidney filtering)

GFR (glomerular filtration rate) is how much blood the kidneys filter each minute. It is usually estimated from a blood test — eGFR, by formulas such as CKD-EPI or MDRD — and some studies ask for it to be measured directly instead. Usually given in mL/min/1.73 m².

Check the method, the units and the minimum the study states. A value of 90 or above is in the normal-or-high range, but kidney damage can show in other tests too.

NYHA class (heart failure)

The New York Heart Association’s four classes of how much heart failure limits physical activity.

I
No limits: ordinary activity causes no undue tiredness or breathlessness.
II
Slight limits: comfortable at rest, ordinary activity causes symptoms.
III
Marked limits: comfortable at rest, less than ordinary activity causes symptoms.
IV
Symptoms even at rest; any activity makes them worse.

Studies set their own limit — many outside heart failure leave out class III–IV, while heart failure studies may ask for a particular class. Check the class this study names.

HbA1c

A blood test of average blood sugar over the past two to three months, given as a percentage or in mmol/mol. 6.5% (48 mmol/mol) or more is the usual threshold for diabetes, normally confirmed by a second test.

What researchers measure

Primary outcomes

  1. Change in GLP-1 induced nausea intensity

    The primary endpoint is the change in GLP-1-induced nausea intensity, measured by a 0-100 mm visual analogue scale (VAS), between study visits, with and without GIP infusion.

    Time frame: From enrollment to the end of treatment at up to 12 weeks.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started May 2026 (actual). Primary completion is estimated for Nov 2026, 6 months after the start.

Of 131 non-industry interventional studies with no phase under Vomiting, half reached primary completion within 13 months of starting (the median), counting those still running; a quarter within 6 and three quarters within 29. This study's planned 6 months is below that.

Counting every sponsor, half of 134 studies reached it within 13 months; a quarter within 6 and three quarters within 31.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jul 7, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
