A Trial to Evaluate Safety, Feasibility and Efficacy of Endoscopic Duodenal PEF Therapy

Prior treatment

• Previous GI surgery that could affect the ability to treat the duodenum such as subjects who have had a Bilroth 2, Roux-en-Y gastric bypass, or other similar procedures or conditions
• Use of anticoagulation therapy (such as phenprocoumon and acenocoumarol) which cannot be discontinued for 3-5 days before and 48 hours after the procedure and novel oral anticoagulants (such as rivaroxaban, apixaban, edoxaban and dabigatran) which cannot be discontinued for 48 hours before and 48 hours after the procedure in accordance with the local protocol
• Use of P2Y12 inhibitors (clopidogrel, pasugrel, ticagrelor) which cannot be discontinued for 5 days before and 48 hours after the procedure in accordance with the local protocol. Use of aspirin is allowed.
• Unable to discontinue NSAIDs (non-steroidal anti-inflammatory drugs) during treatment through 4 weeks post procedure phase
• Taking corticosteroids or drugs known to affect GI motility (e.g. Metoclopramide)
• Receiving weight loss medications such as Meridia, Xenical, or over the counter weight loss medications
• Significant cardiovascular disease, including known history of valvular disease or myocardial infarction, heart failure, transient ischemic attack, or stroke within 6 months prior to the screening visit
• With any implanted electronic devices or duodenal metallic implants
• Not potential candidates for surgery or general anesthesia
• Participating in another ongoing clinical trial of an investigational drug or device that can interfere with the current study.

Other illness

• Known history of severe permanent cardiac arrhythmia's with clinical symptoms
• Active systemic infection
