Magnetic bypass: a new tool against obesity and diabetes?
NCT ID NCT06467955
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests a new magnetic device (MagDI System) that creates a connection between the duodenum and ileum, bypassing part of the small intestine. The goal is to help with weight loss and blood sugar control in 60 adults with obesity and type 2 diabetes. Researchers are checking if the procedure is safe and works as intended.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Magnetic compression device (MagDI System) to create a small bowel bypass
- What this could lead to
- If successful, this could offer a less invasive surgical option for weight loss and type 2 diabetes control.
- What could go wrong
- This is an early feasibility study with only 60 participants. The device may fail to create a lasting bypass, or serious complications like bowel perforation or obstruction could occur.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: 1. Between 18-65 years of age, at the time of informed consent. 2. Body Mass Index (BMI) between 30-50 kg/m2 3. Meets one of the following criteria: 1. Type 2 Diabetes Mellitus (T2DM; defined as HbA1c ≥ 6.5%) or weight regain following previous sleeve gastrectomy (≥ 12 months); OR 2. Type 2 Diabetes Mellitus (T2DM; defined as HbA1c ≥ 6.5%) or weight regain following previous endoscopic sleeve gastroplasty (≥ 12 months); OR 3. Type 2 Diabetes Mellitus (defined as HbA1c ≥ 6.5%) with a Body Mass Index between 30-35 and without previous sleeve gastrectomy and no plan to perform a concurrent sleeve gastrectomy. 4. Participant agrees to refrain from any type of additional bariatric or reconstructive surgery that would affect body weight for the duration of the study. 5. Participant has been informed of the nature of the study and agrees to its provisions, complying with study required testing, medications, follow-up visits, and has provided written informed consent. Exclusion Criteria: 1. Type 1 diabetes. 2. Use of injectable insulin. 3. Uncontrolled Type 2 Diabetes Mellitus (T2DM). 4. Investigator plans to perform a sleeve gastrectomy with the duodeno-ileal anastomosis procedure. 5. Uncontrolled hypertension, dyslipidemia or sleep apnea. 6. Prior intestinal, colonic or duodenal surgery (other than bariatric). 7. Prior surgery, trauma, prostheses, disease or genetic expression which prevent or contraindicate the procedure, including scarring and abnormal anatomy. 8. Refractory gastro-esophageal reflux disease (GERD). 9. Barrett's disease. 10. Helicobacter pylori positive and/or active ulcer disease. 11. Large hiatal hernia. 12. Inflammatory bowel or colonic diverticulitis disease. 13. Any anomaly precluding orogastric access by gastroscope and catheters, and manipulation techniques. 14. Any anomaly preventing / contraindicating endoscopic or laparoscopic access and procedures. 15. Implantable pacemaker or defibrillator. 16. Psychiatric disorder, except well-controlled depression with medication for \> 6 months. 17. History of substance abuse. 18. Pregnant, lactating, or planning pregnancy during the clinical investigation. Note: Female participants of childbearing age must agree to use safe contraception (e.g., intrauterine devices, hormonal contraceptives: contraceptive pills, implants, transdermal patches hormonal vaginal devices, injections with prolonged release). 19. Any comorbidity or current status of participant's physiological fitness that in the surgeon's or anesthesiologist's opinion represents safety concerns that make the participant medically unfit for the procedure, including any significant congenital or acquired anomalies of the GI tract at or distal to the placement of the Magnets. 20. Unhealed ulcers, bleeding lesions, tumor, or any other lesion at target Magnet deployment site. 21. Expected need for Magnetic Resonance Imaging (MRI) within the first 2 months post-procedure. 22. Any surgical or interventional procedure (including planned and/or scheduled) within the period of 30 days prior to and 30 days following the study procedure. 23. Any stroke / Transient Ischemic Attack (TIA) 6 months prior to consent. 24. Requires chronic anticoagulation therapy (except aspirin). 25. Active infections requiring antibiotic therapy, unless resolved before undergoing the study procedure. 26. Recent tobacco or nicotine product cessation 3 months prior to informed consent. 27. Known allergies to the device components (including the biofragmentable material PGLA or similar compounds) or contrast media. 28. Participants with comorbidities that are likely to result in a life expectancy of 12 months. 29. Currently participating in an investigational drug or another device study that has not reached its primary endpoint: Note: Studies requiring extended follow-up for products that were investigational, but have since become commercially available, are not considered investigational trials. 30. A positive COVID-19 test prior to the study procedure in accordance with local COVID-19 protocol. 31. Presence of other anatomic or comorbid conditions, or other medical, social or psychological conditions that, in the investigator's opinion, could limit the participant's ability to participate in the clinical investigation or to comply with follow-up requirements, or impact the scientific soundness of the clinical investigation results.
