About this study

We want to evaluate the impact of the EndoBarrier Gastrointestinal Liner (DJBS) on glucose metabolism as well as gut and pancreatic hormone secretion.

Read the detailed description

Duodenal-jejunal bypass sleeve (DJBS) is being developed for the treatment of obesity, and initial clinical outcomes suggest that this minimally invasive endoscopic technique potentially has beneficial effects on type 2 diabetes also. However, the mechanisms behind the antidiabetic effects of the procedure remain unknown. We want to elucidate how the DJBS might change postprandial secretion of gut and pancreatic hormones.

Questions about this trial

What is this clinical trial studying?

An observational study of Type 2 Diabetes and Obesity, run by Filip Krag Knop 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 5 inclusion and 9 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 10 Aug 2017. 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?

Change in postprandial glucagon-like peptide-1 (GLP-1) secretion from baseline 1 week after implantation (time frame: -30, -15, 0, 10, 20, 30, 40, 50, 60, 90, 120, 150, 180, 240 minutes). 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?
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 10 Aug 2017.
