Trial summary

The prevalence of type 2 diabetes (T2D) is increasing rapidly worldwide. T2D is characterized by a severely impaired incretin effect. The incretin effect refers to the insulinotropic action of the nutrient-released incretin hormones glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic peptide (GIP).

About this study

Official title: Elimination and Biodegradation of the Incretin Hormones GLP-1 and GIP in Patients With End-stage Renal Disease

The prevalence of type 2 diabetes (T2D) is increasing rapidly worldwide. T2D is characterized by a severely impaired incretin effect. The incretin effect refers to the insulinotropic action of the nutrient-released incretin hormones glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic peptide (GIP). The incretin effect is defined as the difference in insulin secretory responses between oral and isoglycaemic intravenous glucose challenges (OGTT and IIGI, respectively) and in healthy individuals it accounts for as much as 70% of the insulin response following oral glucose, whereas patients with T2D exhibit an incretin effect in the range of 0 to 30%. Patients with T2D and non-diabetic patients with severe kidney failure share several pathophysiological characteristics, including decreased insulin sensitivity, fasting hyperinsulinaemia and impaired beta-cell function. The reason for these findings remains to be fully elucidated. An ongoing study in our research group is investigating the incretin effect and the incretin hormone secretory responses following OGTT, IIGI and meal ingestion, respectively. In continuation of this study, essential knowledge of metabolism of incretin hormones in an uremic milieu will be obtained in the present study prior to evaluation of the use of incretin-based agents in patients with impaired kidney function. In this second study we evaluate the elimination and biodegradation of GLP-1 and GIP. The biological active incretin hormones are rapidly degraded by the ubiquitous enzyme dipeptidyl peptidase-4 (DPP-4), generating inactive metabolites. The active hormones are however also eliminated by renal clearance, although the importance of this remains questionable. It is likely that the degradation and elimination of the active hormones will be significantly affected in patients with severe kidney impairment.

We hypothesize that elimination and biodegradation of the two incretin hormones, both in it´s active and inactive forms, will be affected in non-diabetic patients with severe kidney failure.

Questions about this trial

What is this clinical trial studying?

An observational study of Uremia, run by Bo Feldt-Rasmussen 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 11 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 19 Sep 2012. 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. 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?

Intact GLP-1 concentration (time frame: -60 min - 180 min). The study lists 4 primary outcomes in all. 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 NCT01391884, 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 19 Sep 2012.
