简要总结
The objective of this study is to evaluate feasibility, safety, and efficacy of endoscopic DMR Treatment Paradigm 1 (compared to sham) and to evaluate feasibility, safety, and efficacy of re-treatment with DMR at 24 weeks (compared to baseline and a single DMR procedure) in patients with type 2 diabetes with non-insulin glucose lowering medications.
详细描述
The objective of this study is to evaluate feasibility, safety, and efficacy of endoscopic DMR Treatment Paradigm 1 (compared to sham) and to evaluate feasibility, safety, and efficacy of re-treatment with DMR at 24 weeks (compared to baseline and a single DMR procedure) in patients with type 2 diabetes with non-insulin glucose lowering medications.
The aimed effect is an adequate or improved glucose regulation and a decrease of HbA1c. Secondary effects include improved cardiovascular, hepatic, and metabolic parameters.

盲法说明
In this study, both the study team and the study subjects are blinded to the treatment through the 24 week follow-up visit. While the endoscopist is not blinded to individual treatments, he is blinded to cohort level data and is not responsible for patient follow-up. At the 24 week visit, the subject and study team are unblinded. The subjects who received the sham treatment undergo DMR treatment.
