About this study

The most prevalent monogenetic diabetic subtype is named maturity onset diabetes of the young type (MODY3) or hepatocyte nuclear factor 1α (HNF1A)-diabetes. The aim of this study is to evaluate the effects of supra-physiological levels of GIP and GLP-1, respectively, on insulin and glucagon secretion at fasting plasma glucose (FPG) and "post-prandial" PG levels (1.5 × FPG) in patients with HNF1A-diabetes and matched healthy controls treated with or without a low dose of glimepiride (sulphonylurea). In addition, we will evaluate the maximal insulin and glucagon secretory capacity in both groups.

Read the detailed description

A total of 6 experimental days will be performed. The following is an outline of an experimental day:

Participants will meet after a 10-hour fast. A tablet of glimepiride 1.0 mg or placebo will be administered 90 minutes before the initiation of the experiment (-90 minutes) The mean FPG will be calculated from blood samples -105, -100 and -90 minutes. Two intravenous cannulas will be inserted in a cubital vein of each arm. One intravenous cannula will be used for infusions of glucose, arginine and GIP and the other will be used to collect venous blood. The forearm from which blood samples are drawn will be placed in a heating pad (50°C) throughout the experiment for arterialisation of venous blood.

At time 0 minutes, a glucose clamp will be established at the FPG level for 60 minutes and hereafter a post-prandial clamp period of 1.5 × FPG for another 60 minutes. At time 120 minutes, a bolus of 5g of L-arginine (given as 50% arginine HCl) will be infused during 30 seconds. The post-prandial clamp will be maintained for another 10 minutes until time 130 minutes to prevent reactive hypoglycaemia. Throughout the experiment (0-130 minutes) a continuous infusion of either GIP (1.5 pmol/kg/min), GLP-1 (0.5 pmol/kg/min) or placebo (saline) will be administered.

During the experiment PG will be kept stable by a continuous 20%-glucose infusion. The rate of infusion will be regulated according to PG determined by bed-site measurements every 5 minutes. After 60 minutes, a post-prandial clamp will be established by a bolus infusion over one minute using 50%-glucose to target 1.5 × FPG (the amount of glucose to be administered will calculated as follows: (1.5 × FPG - FPG) × 35 mg glucose × weight in kilogram).

    Measured: 0-120 minutes

Secondary outcomes (4)

    Measured: 0-120 minutes

  2. Maximal insulin secretion

    Arginine maximal insulin secretion test.

    Measured: 120-125 minutes

  3. Maximal glucagon secretion

    Arginine maximal glucagon secretion test.

    Measured: 120-125 minutes

  4. Amount glucose used to maintain the glucose clamp

Questions about this trial

What is this clinical trial studying?

A study testing Glimepiride 1Mg Tablet, Glucagon-like Peptide-1 and Glucose-Dependent Insulinotropic Polypeptide in people with Maturity-Onset Diabetes of the Young, Type 3, run by University Hospital, Gentofte, 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 7 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 27 Jun 2019. 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?

Insulin secretion (time frame: 0-120 minutes). 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 NCT03081676, which also lists 1 linked publication.

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 27 Jun 2019.
