Randomisation to Endobarrier Alone Versus With Incretin Analogue in SustainEd Diabesity (REVISE-Diabesity)

April 25, 2016 updated by: Dr Bob Ryder, Sandwell & West Birmingham Hospitals NHS Trust

Randomisation to Endoluminal Intestinal Liner Alone Versus With Incretin Analogue in SustainEd Diabesity (REVISE-Diabesity)

New effective non-surgical treatments are needed for patients whose obesity and type 2 diabetes (T2DM) do not respond to current medical therapies. We propose a randomised controlled trial of Endobarrier, an implantable intestinal device that separates ingested food from contacting the first 60cm of intestine where sited and that mimics some of the clinical effects of bariatric surgery (improved metabolic control with weight loss) with or without continued use of the GLP-1 receptor agonist (GLP-1RA) Liraglutide 1.2mg vs Liraglutide 1.8mg without the device in obese patients with T2DM who remain with suboptimal glycaemic control despite current conventional diabetes treatment, in an NHS setting.

Seventy-two patients with T2DM and obesity (HbA1c≥7.5%, BMI≥35kg/m2) despite previous GLP-1RA therapy will be studied over 24 months and randomised to receive Endobarrier with continued Liraglutide 1.2mg for 12 months; Endobarrier alone for 12 months; or Liraglutide 1.8mg without Endobarrier.

We will investigate potential mechanisms of action and their time course as part of the study by repeated measures of: 1. insulin resistance measures, gut peptides, bile acids; 2. energy intake and nutritional composition; 3. liver fat stores, 4. intestinal inflammation and permeability measures.

The data will inform clinical use of the device and development of new treatments for T2DM and obesity.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Glycated haemoglobin (HbA1c)
Time Frame: 24 months
HbA1c (mmol/mol; %) at end of follow-up period compared to baseline. This will be 12 months following Endobarrier device removal which will usually be 24 months after initial the device has first been implanted (for 12 months) or 24 months from Liraglutide 1.8mg initiation.
24 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Weight
Time Frame: 24 months
Weight (Kg) measured at end of follow-up period compared to baseline. This will be 12 months following Endobarrier device removal which will usually be 24 months after the device has first been implanted (for 12 months) or 24 months from Liraglutide 1.8mg initiation.
