Deep Brain Stimulation (DBS) Intrepid Vercise Device for Parkinson's Disease (A5002)


Study Name

INTREPID STUDY Implantable Neurostimulator for the Treatment of Parkinson’s Disease (IRB no. 30181)


Phase III


The purpose of this study is to evaluate whether an investigational device, the Deep Brain Stimulation (DBS) Vercise system, is safe and effective for the treatment of Parkinson’s disease (PD) symptoms when given in addition to optimal medical therapy in patients with advanced PD that is not adequately controlled by medication alone. Researchers will also evaluate changes in patients’ quality of life, dyskinesia (uncontrollable movements) severity, PD medications, and severity of other PD symptoms. The Vercise DBS system consists of a stimulator with a rechargeable battery, two wires, extension cables and burr hole covers that will be implanted in the body and brain.
