About this study

Official title: A Prospective, Multi-center, Post-market Clinical Follow-up Study of the directSTIM Deep Brain Stimulation (DBS) System

The purpose of this study is to obtain clinical outcome data on safety and effectiveness of the directSTIM DBS system when used on-label, according to the instructions for use.

All participants will undergo bilateral implant in the subthalamic nucleus (STN) and data collected in common practice will be recorded during six months post-implant and analyzed.

Read the detailed description

directSTIM DBS Therapy for Movement Disorders is indicated for patients with disabling tremor or symptoms of Parkinson's disease.

Subjects selected to participate in the study will be Parkinson's Disease (PD) patients who are eligible for bilateral DBS for STN therapy and meet the inclusion criteria and none of the exclusion criteria.

Primary safety and effectiveness endpoints data will be collected through 6 months of follow-up. The values used for comparison are derived from a review of literature spanning from 2001 to 2019.

After completing the 6 month follow-up, subject will exit the study, and continue to be followed by their physician per usual care.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Deep Brain StimulationProcedure or surgery

    Patients with PD who are eligible to bilateral STN DBS surgery and chose to get directSTIM System implanted will be followed over a 6-month period to evaluate changes in their condition.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in UPDRS III score without medication

    Part 3 of the Unified Parkinson's Disease Rating Scale (UPDRS III), is a series of questions evaluated by the clinician in presence of the patient, focusing on motor symptoms of PD.

    Score is expressed on a scale of 0 to 108. This score is evaluated at baseline and 6 months post-implant without any anti-Parkinson medication taken.

    A decrease at 6 months compared to baseline indicates an improvement. The average difference of scores between the two time points is calculated for the whole study subject population.

    This value is to be compared to the results of a meta-analysis performed on data extracted during a literature search.

    Measured: 6 months compared to baseline

  2. Materiovigilance

    Summary statistics on the occurrence of the following categories of adverse events (AEs):

    • Device-related AEs
    • Procedure-related AEs
    • Stimulation-related AEs

    Measured: 6 months

Secondary outcomes (2)
  1. Therapeutic Window (TW)

    The therapeutic window is the difference of electrical current values between the stimulation settings that provide maximum alleviation of motor symptoms and the settings for which the first stimulation-induced side effect appears (e.g., eye deviation, muscle contraction, speech impairment).

    The wider this window, the more flexibility is offered to the patient for stimulation without causing side-effects.

    Measured: 3 months

  2. UPDRS

    Other parts (I, II and IV) of the Unified Parkinson's Disease Scale are evaluated at baseline and 6 months post-implant.

    Part I is a series of 4 questions assessing Mentation, Behavior and Mood. Patient's score is expressed on a scale of 0 to 16.

    Part II is a series of 13 questions assessing Quality of Life in daily activities. Patient's score is expressed on a scale of 0 to 52.

    Part IV is a series of 10 questions assessing Complications of Therapy. Patient's score is expressed on a scale of 0 to 23.

    A decrease at 6 months compared to baseline indicates an improvement.

    Measured: 6 months

Questions about this trial

What is this clinical trial studying?

A study testing Deep Brain Stimulation in people with Parkinson Disease, run by Aleva Neurotherapeutics SA at 6 sites in Germany.

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 4 inclusion and 12 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: status not confirmed, as of the sponsor's last update on 9 Nov 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 6 sites in Germany. 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. 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?

Results are not available in the source record.

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

Contact Alain Dransart (+4121 353 8764, clinical@aleva-neuro.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in UPDRS III score without medication (time frame: 6 months compared to baseline). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 9 Nov 2023.
