About this study

The objective of this study is to investigate the potential GLP-1-mediated contribution to the well-established glucose-lowering effect of sevelamer-induced bile acid sequestration . Exendin9-39 has been demonstrated to act as a potent and specific GLP-1 receptor antagonist with no partial agonistic potential and is considered a useful tool in the assessment of GLP-1 physiology. The aim is to evaluate any contribution of sevelamer-induced GLP-1 secretion to the reduced plasma glucose concentrations observed after treatment with sevelamer. A randomised placebo-controlled cross-over study involving two 17-day treatment periods with sevelamer and placebo, respectively, in metformin-treated patients with type 2 diabetes, will be conducted. The impact of bile acid sequestration on GLP-1 secretion and effect will be examined during two randomised experimental days after 15 and 17 days of treatment with sevelamer (1,600 mg three times a day) and placebo, respectively. During each of these two experimental days, a meal test with concomitant exendin9-39 infusion or placebo will be performed (for evaluation of any GLP-1-mediated effects). Postprandial plasma glucose excursion is the primary endpoint, and secondary endpoints include postprandial plasma/serum excursions of insulin, C-peptide, GLP-1, glucagon, glucose-dependent insulinotropic polypeptide (GIP), glucagon-like peptide-2 (GLP-2), peptide YY (PYY), oxyntomodulin, ghrelin, fibroblast growth factor (FGF)-19, FGF-21, C4 (an intermediate in the de novo synthesis of bile acids), cholecystokinin (CCK), bile acids and plasma lipids. Furthermore, gastric emptying, gallbladder emptying, liver fat content, appetite and ad libitum food intake will be examined.

  14. Gastric emptying

    Gastric emptying measured by paracetamol absorption test. Paracetamol is ingested along with meal, the appearance in blood will be calculated as a measure of gastric emptying.

    Measured: -30 minutes to 240 minutes with ingestion of a meal and paracetamol at 0 minutes

  15. Rate of gall bladder emptying

    Gall bladder volumen measured by ultrasound over time after a meal (see time frame below). The rate of gall bladder emptying will be calculated

  16. Liver stiffness and fat

    Liver stiffness and fat content measured by fibroscan

    Measured: At initiation and after 15 days of treatment with sevelamer/placebo

  17. Appetite measured by visual analog scale

    We assessed appetite parameters (hunger, satiety, fullness, prospective food consumption) and well-being, nausea, and thirst by visual analogue scales. Overall appetite score (OAS) will be calculated as (satiety + fullness + (100 - hunger) + (100 - prospective food consumption)

    Measured: -30 minutes to 240 minutes with ingestion of a meal at 0 minutes

Questions about this trial

What is this clinical trial studying?

A study testing Sevelamer in people with Type 2 Diabetes Mellitus, run by Steno Diabetes Center Copenhagen at 1 site in Denmark.

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 8 inclusion and 11 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 Oct 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 Denmark. 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?

plasma glucose (time frame: -30 minutes to 240 minutes with ingestion of a meal at 0 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 13 Oct 2021.
