Post Market (Brio™ System) Deep Brain Stimulation (DBS) PD Study

Status Withdrawn

Clinical Trial Summary

The objective of this study is to evaluate the effectiveness of a rechargeable 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.

This is the first observational study for the use of the BRIO™ rechargeable constant current device, using a lead with an active electrode tip for deep brain stimulation in Parkinson subjects. The current study was designed to conform to normal medical practices, taking into consideration the current day economic constraints, while assessing the best set of circumstances for the successful sustained reduction of some of the symptoms of advanced, levodopa-responsive Parkinson's disease that are not adequately controlled with medication.

Clinical Trial Description

This study is designed as a prospective, observational, non-randomized, multi-centered study for a total of 10 years in duration. It is a 10 year study from system implantation and activation with a yearly database lock and report, with the subjects being used as their own control. The primary outcome assessment will occur at three months. Following completion of the primary outcome assessment, patients will have an annual visit up to 10 years post implant.

Comparison of measures within the same person from pre-treatment to post-treatment will be performed.

During the implantation procedure, each subject will undergo a trial of stimulation in the operating room among other potential assessments to determine proper lead placement. The device may be internalized after a successful intra-operative trial or at a later date according to investigator site practice. The date that all components are implanted and programmed will be classified as "Day 0". After system activation the subject will return to clinic for post-operative evaluations at 1 month (+/-14 days), 3 months (+/-14 days), 6 months (+/-14 days) and 12 months (+/-30 days). Thereafter, a long term data collection program will be followed for 10 years post-implant. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
