A Prospective, Multi-center, Randomized Controlled Blinded Trial Demonstrating the Safety and Effectiveness of VNS Therapy? System as Adjunctive Therapy Versus a No Stimulation Control in Subjects With Treatment-Resistant Depression
This blinded, randomized, multicenter controlled study is intended to collect evidence that VNS Therapy as an adjunctive therapy improves health outcomes for patients with TRD. The objective of this study is to determine whether active VNS Therapy treatment improves health outcomes for Treatment Resistant Depression (TRD) subjects compared to a no stimulation control in depressive symptoms. This prospective, multicenter trial is composed of two parts: - The RCT and Follow-up (RCT) is a randomized, controlled, blinded trial to determine if active VNS Therapy treatment compared to a no stimulation control improves depressive symptoms. - The Longitudinal Registry (LR) is an observational, open label, single arm study aimed at assessing the long-term effectiveness and safety of VNS Treatment.
