About this study

Randomized, Single-Center, Parallel-group, Open-label Pilot Study to Evaluate the Safety and Effectiveness of the GI Windows Magnet Anastomosis System (MAS) When Used to Create a Dual-path Enteral Diversion Compared with Medical Therapy Alone To Effect Glycemic Control in Obese Patients with Type 2 Diabetes Mellitus (T2DM)

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Body mass index (BMI) 30 to 50.
  • Subject Type 2 Diabetes Criteria:
  • T2DM diagnosis ≥6 months but < 10 years
  • On 1 or more oral diabetes medications (with one at the minimum recommended therapeutic dose)
  • Hemoglobin A1C (HbA1c) between and including 6.5 and 10.0% (58 mmol/mol to 86 mmol/mol) at time of enrollment and has had a stable HbA1c over a 3-month period (i.e., <0.3% reduction)
  • Stable medication regimen (i.e., no change in diabetes medications) for at least 3 months prior to Screening Visit.
  • If subject has obesity-related comorbidities such as hypertension, dyslipidemia, and sleep apnea, these comorbidities must be well-controlled.
  • Able to understand and sign informed consent document
  • Has primary care physician and/or endocrinologist who follows patient for all comorbid conditions

Exclusion criteria

  • Known or suspected allergy to nickel or titanium or Nitinol
  • Type 1 Diabetes
  • Use of injectable insulin
  • Uncontrolled T2DM Fasting glucose ≥ 200 mg/dl (11.1 mmol/L)
  • Probable insulin production failure, defined as fasting serum C Peptide <1 ng/mL (0.3 nmol/l)
  • Any documented conditions for which endoscopy/colonoscopy would be contraindicated.
  • Contraindication to general anesthesia
  • Congenital or acquired anomalies of the GI tract, including atresias, stenosis or malrotation.
  • Any previous major surgery on the stomach (excluding sleeve gastrectomy), duodenum, hepatobiliary tree (excluding gallbladder), pancreas or right colon.
  • Previous technically difficult or failed colonoscopy or endoscopy
  • If on metformin, history of polycystic ovarian syndrome (PCOS)
  • Unable or unwilling to perform home blood glucose monitoring
  • History of or suspected gastrointestinal disease (e.g. cirrhosis, inflammatory bowel disease)
  • Diagnosis of active malignancy (i.e. not in remission) with the exception of squamous or basal cell carcinoma of the skin
  • Previous surgical or endoscopic treatment for obesity including but not restricted to intragastric balloons, endoscopic suturing or stapling procedures, malabsorptive sleeves.
  • Specific genetic or hormonal cause of obesity (e.g. Prader-Willi syndrome)

Treatment and study plan

Magnet Anastomosis System

Device

The MAS will be placed using an endoscope in the duodenum and and laparoscopically into ileum. A compression anastomosis will be created in each of the patients and the diversion of enteral flow from the duodenum to ileum treats Type 2 diabetes.

Other names: MAS

Best Medical Management

Drug

The best medical management for the patients in this arm will be decided by the endocrinologist based on protocol parameters.

Other names: No other intervention

Primary outcomes

  1. Mean change in HbA1c

    Time frame: 12 months

    The primary effectiveness endpoint is Mean change in HbA1c from baseline

Secondary outcomes

  1. Mean change in Weight

    Time frame: 12 months

    12 month weight loss measured as a percent of total body weight loss and excess weight loss (using the BMI method) as well as weight/BMI change from baseline

  2. Proportion of subjects achieving remission

    Time frame: 12 months

    Proportion of subjects experiencing diabetes remission and/or partial remission at 12 months (as defined by the American Diabetes Association)

  3. Mean change in diabetes medication

    Time frame: 12 months

    Change in diabetes medication requirements from baseline to 12 months
