GI Dynamics Announces Results of EndoBarrier® Therapy Studies at Digestive Disease Week Meeting


GI Dynamics, Inc. (ASX:GID), a medical device company that has developed an innovative endoscopically delivered treatment for type 2 diabetes and obesity, today announced the results of clinical studies involving EndoBarrier Therapy that were presented during Digestive Disease Week, the annual meeting of the American Gastroenterological Association.

The presentations summarized below represent investigator-initiated studies.

  • Endoscopic treatment of obesity with a duodenal-jejunal bypass sleeve:
    Does impairment of fat absorption explain weight loss?
    Gerald Holtmann, M.D., Ph.D., et al., School of Medicine, University of Queensland, Brisbane, Australia

    This study assessed changes in fat absorption and meal-related symptoms before and after EndoBarrier implantation in obese type 2 diabetes patients, and also analyzed the correlation between these factors and weight loss.

    Interim results after 34 weeks of implant duration showed a median weight loss of 18.2 kg (40 lbs.) or 15.5% total body-weight loss. The intensity of meal-related dyspepsia (indigestion) was seen as positively correlated to weight loss. There was no correlation between weight loss and fat absorption, indicating that the reduction in weight and HbA1c achieved with EndoBarrier Therapy were not the result of fat malabsorption.

  • Endoscopic proximal intestinal exclusion can improve non-alcoholic fatty liver disease (NAFLD) in patients with diabesity
    Bu Hayee, Ph.D., King's College Hospital NHS Foundation Trust, London, U.K.

    This study investigated the impact of EndoBarrier Therapy (EBT) on non-alcoholic fatty liver disease (NAFLD) with or without an additional GLP-1 receptor agonist (liraglutide), a non-insulin medicine prescribed to lower blood sugar levels.

    Seventy adults with uncontrolled type 2 diabetes and obesity who had been taking 1.2 mg of liraglutide daily were randomized into three treatment groups:
  • EndoBarrier Therapy plus liraglutide (1.2 mg)
  • EndoBarrier Therapy only
  • Liraglutide alone with an escalated dose (1.8 mg daily)

    Changes in weight, hemoglobin A1C (HbA1c) and NAFLD fibrosis score (NFS) were calculated over three months within groups. A subset of EBT subjects underwent magnetic resonance imaging (MRI) to quantify hepatic fat prior to and four months after completing EndoBarrier Therapy.

    NFS scores for study subjects categorized as high risk for NAFLD were reduced for both EBT groups (33% and 35%, respectively, to 14%), but not for the liraglutide-only group. The cohort of EBT subjects that underwent MRI four months post-EndoBarrier removal experienced an 80.5% reduction (from 14.9% to 2.9%) in hepatic fat.

    Despite previous suboptimal response to liraglutide treatment, EndoBarrier Therapy was effective at reducing hepatic fat. These data suggest that EndoBarrier Therapy may be an effective future treatment for patients with NAFLD.

"We're very pleased that EndoBarrier Therapy was well represented at Digestive Disease Week this year," stated Scott Schorer, president and CEO of GI Dynamics, Inc. "These studies add to the body of clinical evidence supporting the safety and efficacy of EndoBarrier Therapy for treating obese type 2 diabetes. Further to that, they advance our understanding of EndoBarrier Therapy's mechanism of action and its effect on NAFLD.

"I would like to thank Drs. Hayee and Holtmann and their esteemed colleagues for their continued contribution to the science of EndoBarrier Therapy."
