简要总结
This is a prospective, multicenter, randomized, double-blind, sham-controlled, adaptive study evaluating the pulsENDO system in individuals with type 2 diabetes (T2D) inadequately controlled on non-insulin glucose-lowering medications (GLMs). The primary objective of this study is to demonstrate that pulsENDO therapy is superior to sham control for improving glycemic control in adults with type 2 diabetes.
详细描述
This is a prospective, multicenter, randomized, double-blind, sham-controlled, adaptive study evaluating the pulsENDO system in individuals with type 2 diabetes (T2D) inadequately controlled on non-insulin glucose-lowering medications (GLMs).
The study enrolls two sequential cohorts. An initial open-label run-in cohort (n=30) generates early safety data to support FDA review of the pulsENDO system. This is followed by an adaptively designed randomized cohort of up to 320 participants (target 250), randomized 2:1 to pulsENDO therapy or a sham control procedure. Participants in both cohorts are followed for 12 months post-procedure. The primary effectiveness endpoint is assessed at Month 6 in the randomized cohort.
