简要总结
The Gastric Bypass Stent System is intended to be used in weight loss treatment for obesity in patients with a BMI ≥ 30 kg/m2. In this clinical investigation the Sponsor seeks to demonstrate the safety and performance of the Gastric Bypass Stent System for its proposed indication in weight loss treatment for obesity in the European Union (EU) and United Kingdom (UK).
详细描述
The Gastric Bypass Stent System is intended to be used in weight loss treatment for obesity in patients with a BMI ≥ 30 kg/m2. In this pivotal, prospective, multicenter, single-arm clinical investigation the Sponsor seeks to demonstrate the safety and performance of the Gastric Bypass Stent System for its proposed indication in weight loss treatment for obesity in the European Union (EU) and United Kingdom (UK). This clinical investigation will be used as an EU/UK bridging study and, with the ongoing clinical investigation in China (Protocol number: HZTG01), will be used to evaluate the safety and performance of the investigational device for the intended use.

- •Patients with secondary obesity; a medical condition that has caused weight gain such as endocrine disorders and hypothalamic disorders.
- •Chronic, daily use of systemic anti-inflammatory or corticosteroid medications (e.g., ibuprofen, prednisolone) for more than 1 week (not including low-dose aspirin for cardiac prophylaxis or inhaled corticosteroids).
- •Patients with less than one-year continuous treatment before baseline with hypoglycemic drugs with known weight loss effects (e.g., GLP-1 agonists, SGLT-2 inhibitors, DDP-4 inhibitors).
- •Patients diagnosed with type 1 diabetes.
- •Patients with the function of islet β cell basically lost, C-peptide ≤ 1/2 of the normal low limit, or low and flat C-peptide release curve under glucose load.
- •Patients with significant iron deficiency or iron deficiency anemia upon the Investigator's discretion.
- •Patients with coagulation dysfunction and chronic, daily use of systemic anti-inflammatory or anti-coagulation medication in the past month (not including low-dose aspirin).
- •Patients with severe liver and kidney dysfunction, and a serum creatinine concentration ≥ 180 μmol/L.
- •Patients with Class III heart function of New York Heart Association Functional Classification (NYHA) or higher upon the Investigators evaluation.
- •Patients with pulmonary dysfunction upon the Investigator's evaluation.
- •Patients who have undergone Endoscopic Retrograde Cholangiopancreatography (ERCP) or have a history of cholecystitis or liver abscess.
- •Patients with a duodenal ulcer, gastric ulcer, or previous and existing pancreatitis.
- •Patients with gallstones (diameter ≥ 20 mm) with clinical symptoms.
- •Patients with on-going thyroid dysfunction, not stabilized despite appropriate treatment.
- •Patients with hemorrhage or potential hemorrhage in the digestive tract.
- •Patients with gastrointestinal tract anomalies, such as gastrointestinal tract atresia, or other conditions that would result in failed placement in the gastrointestinal tract.
- •Patients with a history of bowel obstruction or related diseases in the past year.
- •Patients with a history of systemic lupus erythematosus or scleroderma.
