  Purpose

The objective of this study is to evaluate the effectiveness of Deep Brain Stimulation as an adjunctive treatment for reducing some of the symptoms of advanced, levodopa-responsive Parkinson's disease that are not adequately controlled with medication.

It will be the first study in Parkinson's patients outside the US with a Deep Brain Stimulation system using constant current instead of constant voltage and using a lead with an active electrode tip.

Primary Outcome Measures:
  • UPDRS motor scores [ Time Frame: [Time Frame: 3 months after device implantation]. ] [ Designated as safety issue: No ]
    Comparison of Parkinson's symptoms as demonstrated by the UPDRS motor scores in the medication 'Off' state at Baseline compared to the medication 'Off' with stimulation "On" 3 months after device implantation


Secondary Outcome Measures:
  • Satisfaction of therapy [ Time Frame: [through 3, 6 months and 1 year] ] [ Designated as safety issue: No ]
    Rate of subject and caregivers therapy satisfaction through 3, 6 month and 1 year

  • Economic burden of the disease [ Time Frame: [at baseline and 1 year] ] [ Designated as safety issue: No ]
    Rate on economic burden of the disease for caregiver determined from economic burden questionnaire at baseline and 1 year

  • Rating on caregiver's burden determined from Zarit Caregivers Burden Interview (ZCBI) [ Time Frame: [at baseline, 3 month and 1 year] ] [ Designated as safety issue: No ]
  • Assessment of the way of coping as determined from the Way of Coping Checklist (WCC) from caregiver [ Time Frame: [baseline, 3,6 month and 1 year] ] [ Designated as safety issue: No ]

Estimated Enrollment: 30
Study Start Date: May 2011
Estimated Primary Completion Date: July 2013 (Final data collection date for primary outcome measure)
Detailed Description:

This study is designed as a prospective, observational, non-randomized, multi-centered study for 12 months in duration from implantation with the subjects being used as their own control. The primary outcome assessment will occur at three months: however, subjects will be followed for one year.

A comparison of measures within the same person from pre-treatment to post-treatment will be performed. Also, pre-treatment and post-treatment group means and standard deviations will be determined.

Study Population

Libra™/LibraXP™ DBS System Eligible subjects in this study will be screened to confirm that they meet the strict guidelines for advanced, levodopa-responsive Parkinson's disease that are not adequately controlled with medication followed by surgery to implant the Libra™/LibraXP™ deep brain simulation system.

Criteria

Inclusion Criteria:

Subjects enrolled in this study must meet the following inclusion criteria:

  3. Subject is a candidate for surgery.
  4. Subject is 18 to 80 years of age.
  5. Subject has a history of improvement of Parkinson's symptoms as a direct result of administering l-dopa to the subject with at least a 25% improvement in Unified Parkinson's Disease Rating Scale (UPDRS) motor score or subject has been diagnosed with tremor-dominant Parkinson's disease.
  6. Subject should be stable on anti-Parkinson's disease medication for at least one month prior to study enrollment.

Exclusion Criteria:

Subjects will be excluded from the study if they meet any of the following criteria:
