    Clinical trials


    ImpactTD Registry: A prospective multicenter study to characterize the natural history of tardive dyskinesia (TD) and investigate the real-world effectiveness of deutetrabenazine on the multidimensional impact of TD

    Active recruiting

    TV50717-CNS-40223: The purpose of this study is to get a better understanding of the disease course of tardive dyskinesia and the impact it has on individuals’ lives. In subjects who may begin on deutetrabenazine (AUSTEDO®) treatment during the study, it will also help investigate the real-world effectiveness of this treatment, particularly on a person’s quality of life.


    RECOVER: 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

    Active recruiting

    The RECOVER study is a nationwide clinical trial that has been approved by Medicare to provide additional evidence for the benefits of Vagus Nerve Stimulation (VNS) Therapy.  Vagus Nerve Stimulation Therapy is an FDA-approved device for treating patients with TRD (Treatment Resistant Depression). It is implanted in the left chest area during a short outpatient procedure. The device delivers mild, intermittently pulsed signals to the vagus nerve in the neck that activate various parts of the brain.
