About this study

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.

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.

Read the 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.

Questions about this trial

What is this clinical trial studying?

A study testing Libra Deep Brain Stimulation System in people with Parkinson Disease and Movement Disorders, run by Abbott Medical Devices at 15 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 4 Feb 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 15 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Increase the duration of "on time" without dyskinesias or with non-bothersome dyskinesias (time frame: 90 days). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00552474, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 4 Feb 2019.
