About this study

Official title: Effects of Lixisenatide on Gastric Emptying, Glycaemia and 'Postprandial' Blood Pressure in Type 2 Diabetes and Healthy Subjects.

The purpose of this study is to determine the effects of the drug lixisenatide on blood sugar levels, stomach emptying, blood pressure and heart rate, release of gut hormones and blood flow in the gut after a glucose drink in both healthy subjects and people with type 2 diabetes. If lixisenatide is shown to be effective, it would encourage ongoing evaluation of its potential use in the management of the falls in blood pressure following a meal in diabetic patients.

Read the detailed description

Lixisenatide is a drug that has been shown to reduce postprandial glycaemia in people with type 2 diabetes and is now approved for use in Australia. Although slowing of gastric emptying is likely to be the dominant mechanism by which lixisenatide reduces postprandial glycaemia after a meal, the effects of lixisenatide on gastric emptying have hitherto not been quantified by the 'gold standard' technique of scintigraphy. The study would determine and evaluate for the first time the magnitude of, and the relationship between lixisenatide on glycaemia with those on gastric emptying with scintigraphy. This information will be of fundamental significance to the effective use of lixisenatide in the management of people with type 2 diabetes that suffer from postprandial hypotension.

Postprandial hypotension represents an important clinical disorder that occurs frequently in the elderly and people with type 2 diabetes and for which current management is suboptimal. While the mechanisms mediating postprandial hypotension are poorly understood, impaired regulation of splanchnic blood flow, gastric distension, the rate of small intestinal delivery and neural and hormonal mechanisms have been identified as possible pathophysiological mechanisms. Meal ingestion is associated with splanchnic blood pooling and a consequent reduction in venous return of blood to the heart. In healthy young and older individuals, with intact baroreflex mechanisms, these changes induce a rise in heart rate, stoke volume and cardiac output leading to a compensatory rise in blood pressure. However, patients with postprandial hypotension, these responses are inadequate to maintain blood pressure. The magnitude of the fall in blood pressure is greater when gastric emptying is more rapid and that slowing gastric emptying can markedly attenuate the postprandial fall in blood pressure in both healthy older subjects and type 2 patients.

There is currently no information about the effect of lixisenatide on postprandial blood pressure and splanchnic blood flow in patients with type 2 diabetes.

The purpose of this study would determine whether lixisenatide reduces the postprandial fall in blood pressure and related effects of gastric emptying to those on blood pressure, heart rate and splanchnic blood flow.

The use of lixisenatide on appetite and energy intake and how these relate to effects of gastric emptying is lacking.

It is hypothesized that lixisenatide will slow gastric emptying of oral glucose; attenuate both fasting and the postprandial rise in blood glucose; attenuate the magnitude of the fall in blood pressure, rise in heart rate and increase in SMA flow and reduce hunger, increase fullness and decrease energy intake at a buffet meal with greater effects in patients with type 2 diabetes that healthy subjects.

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Lixisenatide in people with Diabetes Mellitus and Gastroparesis, run by Royal Adelaide Hospital at 1 site in Australia.

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 7 inclusion and 18 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: status not confirmed, as of the sponsor's last update on 29 Oct 2015. 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 Australia. 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 combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Rachael S Tippett, BSc Honours (8222 2915 ext. 2915, rachael.tippett@adelaide.edu.au), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Blood Pressure (time frame: 4.5 hours per study). 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 NCT02308254, which also lists 38 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 29 Oct 2015.
