Deep Brain Stimulation to Treat Symptoms of Parkinson's Disease

This study has been completed.

St. Jude Medical Identifier:
First received: October 31, 2007
Last updated: February 22, 2017
Last verified: February 2017
The purpose of this study is to evaluate the safety and efficacy of bilateral stimulation of the subthalamic nucleus (STN) of the brain when using the ANS Totally Implantable Deep Brain Stimulation System as an adjunctive treatment for reducing some of the symptoms of Parkinson's Disease that are not adequately controlled with medication.

Condition Intervention
Parkinson Disease
Movement Disorders
Device: Libra Deep Brain Stimulation System

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: No masking
Primary Purpose: Treatment
Official Title: A Clinical Evaluation of Bilateral Stimulation of the Subthalamic Nucleus (STN) Using the ANS Totally Implantable Deep Brain Stimulation System as an Adjunctive Treatment for Reducing Some of the Symptoms of Advanced, Levodopa-responsive Parkinson's Disease That Are Not Adequately Controlled With Medication.

Primary Outcome Measures:
  • Increase the duration of "on time" without dyskinesias or with non-bothersome dyskinesias [ Time Frame: 90 days ]

Secondary Outcome Measures:
  • Changes in the following over time: Incidence of AEs; UPDRS motor scores; Activities of Daily Living; Quality of Life, Quality Sleep Index, Hoehn and Yahr Staging, Global Outcome evaluation and Patient Satisfaction [ Time Frame: 1 year ]

Other Outcome Measures:
  • Efficacy [ Time Frame: Yearly for 5 years ]
    Reduction in Parkinson's symptoms as demonstrated by the total UPDRS scores and each individual component of the UPDRS in the medication on and off state with stimulation on at 2 years, 3 years, 4 years, and 5 years.

  • Quality of life [ Time Frame: up to to 5 years ]
    Quality of Life measurements as measured by the Parkinson's Disease Questionnaire (PDQ 39)

  • Activites of Daily Living [ Time Frame: up to 5 years ]
    Activities of Daily Living measurement at 2 years, 3 years, 4 years, and 5 years as determined from the Unified Parkinson's Disease Rating Scale (UPDRS) in the medication on and stimulation on state

Active Stimulation
Device: Libra Deep Brain Stimulation System
Active DBS Therapy

Detailed Description:

This is a prospective, controlled, multi-centered, 12 months post-implantation study. A maximum of 15 sites will enroll a total of 136 patients.

All study participants will have the study device surgically implanted. After implant surgery, study participants will return to the clinic for evaluation 30 days after surgery, three months after surgery, six months after surgery and twelve months after surgery. At the baseline, three, six and twelve month visits the patient's Parkinson's symptoms and ability to perform daily activities will be evaluated using a number of accepted assessment tools including a Dyskinesia diary, evaluation of PD symptoms, quality of life scoring and patient extension study to monitor the safety and efficacy of the ANS Libra/Libra Deep Brain Stimulation System.

After the 1 year study, patients may enter another protocol (C-06-04) to continue to monitor the safety and efficacy of the Libra Deep Brain Stimulation System. Patients may be followed for an additional 4 years.

If necessary, patients may continue to have access to the investigational device under protocol (C-13-02) which allows for compassionate use access to it.
