About this study

In the current study we wish to investigate the effects on glucagon-like peptide-1 (GLP-1) of a neprilysin inhibitor

Read the detailed description

Glucagon-like peptide-1(GLP-1) is secreted during a meal and increases glucose induced insulin secretion. The enzyme dipeptidyl peptidase 4(DPP-4) cleaves intact GLP-1 within minutes and DPP-4 inhibitors are therefore used for treatment of diabetic hyperglycemia. A few animal studies have implicated the enzyme neutral endopeptidase 24.11 (24.11) in the degradation of GLP-1 but if this is the case in humans is unknown. We therefore administered a NEP inhibitor, 194mg sacubitril, a DPP-4 inhibitor (sitagliptin 100mg the night before and 100mg 2 hours before), both, or place, to nine healthy men during a standardized meal and measured plasma concentrations of GLP-1

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. GLP-1

    changes in plasma GLP-1 using immunological methods: intact and total GLP-1

    Measured: 3 hours after treatment ( during the subsequent standardized meal)

Secondary outcomes (2)
  1. C-peptide

    changes in C-peptide using immunological methods

    Measured: 3 hours after treatment ( during the subsequent standardized meal)

  2. Glucagon

    Changes in Plasma glucagon concentrations using different analytical methodologies

    Measured: 3 hours after treatment ( during the subsequent standardized meal)

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Entresto and Sitagliptin 100mg in people with Diabetes and Heart Failure, run by Nicolai Jacob Wewer Albrechtsen 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 2 inclusion and 5 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 8 Jul 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.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

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?

GLP-1 (time frame: 3 hours after treatment ( during the subsequent standardized meal)). 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 NCT03717688, which also lists 2 linked publications.

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 8 Jul 2019.
