Study for Short Term Weight Loss in Candidates for Bariatric Surgery

August 3, 2016 updated by: GI Dynamics

A Pilot Trial of the GI EndoBarrier Liner for Short Term Weight Loss in Subjects Who Are Candidates for Bariatric Surgery

The purpose of this study is to determine whether the GI Endobarrier Liner is safe and effective.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Patients with obesity are at significantly greater risk of developing significant co-morbid complications, and are associated with an increased risk in all-cause mortality. The GI Endobarrier Liner represents a viable alternative to other short-term weight loss methods. It is a minimally invasive endoscopic procedure, which may allow patients to recover faster with less morbidity and mortality. This study is investigating the safety and efficacy of the GI Endobarrier Liner in patients who are candidates for bariatric surgery.

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.

Ages Eligible for Study

18 years to 55 years (Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Description

Inclusion Criteria:

  • Age > 18 years and < 55 years - Male or Female

  • Pregnant or have intention of becoming pregnant for the duration of the trial
  • Unresolved alcohol or drug addiction
  • Receiving weight loss medications (prescription, over-the-counter, or herbal dietary medications)
  • Previous gastrointestinal surgery that could affect the ability to place the EndoBarrier Liner or the function of the implant
  • Active GERD

  • Participating in another ongoing investigational clinical trial
  • Mentally retarded or emotionally unstable, or exhibits psychological characteristics requiring medication that affects appetite (i.e. tricyclic antidepressants and atypical antipsychotic medications) which, in the opinion of the Investigator, makes the subject a poor candidate for device placement or clinical trial

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
Assessment of % Excess Weight Loss
Time Frame: 12 months
Primary efficacy was assessment of the percent excess weight loss (%EWL) at Week 52 or last assessment. Excess weight was determined from ideal body weights based on a body mass index (BMI) of 25 kg/m2. Percent excess weight loss from baseline to 12 months was calculated as [(baseline weight minus the 12-month weight) / (baseline weight minus the ideal body weight)] * 100).
12 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
Improvement in Type 2 Diabetic Status
Time Frame: 12 months
Subjects who achieved HbA1c reduction of 0.5%
12 months
