About this study

Official title: A Prospective, Multicenter, Randomized Controlled Clinical Study Evaluating the Efficacy and Safety of Rechargeable Implantable Deep Brain Stimulation System for the Treatment of Parkinson's Disease

The purpose of this clinical trial is to verify the efficacy and safety of rechargeable implantable deep brain stimulation (DBS) system for the treatment of advanced primary Parkinson's disease.

Read the detailed description

This study is a prospective, multicenter, randomized controlled superiority clinical study. According to the unified inclusion and exclusion criteria, 60 eligible subjects are enrolled in this clinical trial. All subjects are implanted with bilateral deep brain stimulation leads, and are randomly assigned to the experimental group or control group in a 1:1 ratio. Within one month after surgery, the DBS system of experimental group is activated and the stimulation parameters are modulated, whereas the control group is not activated. The primary endpoint is the change in motor examination scores evaluated using the Movement Disorder Society-sponsored revision of the Unified Parkinson's Disease Rating Scale (MDS-UPDRS) part III (MDS-UPDRS-III) in "med off" state at 3 months after surgery, compared to the baseline. After primary endpoint evaluation, both groups receive treatment with activated DBS system. The efficacy in med off/stim on and med on/stim on state and the safety are evaluated at 6 months after surgery.

What is being measured

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

  1. Change in motor examination score evaluated using the Movement Disorder Society-sponsored revision of the Unified Parkinson's Disease Rating Scale (MDS-UPDRS) Part Ⅲ in "med off" state relative to baseline

    MDS-UPDRS Part Ⅲ (MDS-UPDRS-Ⅲ) scores range from 0 to 132, higher scores mean a worse outcome.

    Measured: 3 months after surgery

Secondary outcomes (10)
  1. Change in motor examination score evaluated using the Movement Disorder Society-sponsored revision of the Unified Parkinson's Disease Rating Scale (MDS-UPDRS) Part Ⅲ in "med on" state relative to baseline

    MDS-UPDRS Part Ⅲ (MDS-UPDRS-Ⅲ) scores range from 0 to 132, higher scores mean a worse outcome.

    Measured: 3 months after surgery

  2. Change in motor experiences of daily living score evaluated using the Movement Disorder Society-sponsored revision of the Unified Parkinson's Disease Rating Scale (MDS-UPDRS) Part Ⅱ relative to baseline

    MDS-UPDRS Part Ⅱ (MDS-UPDRS-Ⅱ) scores range from 0 to 52, higher scores mean a worse outcome.

    Measured: 3 and 6 months after surgery

  3. Change in non-motor experiences of daily living score evaluated using the Movement Disorder Society-sponsored revision of the Unified Parkinson's Disease Rating Scale (MDS-UPDRS) Part Ⅰ relative to baseline

    MDS-UPDRS Part Ⅰ (MDS-UPDRS-Ⅰ) scores range from 0 to 52, higher scores mean a worse outcome.

    Measured: 3 and 6 months after surgery

  4. Change in motor complications score evaluated using the Movement Disorder Society-sponsored revision of the Unified Parkinson's Disease Rating Scale (MDS-UPDRS) Part Ⅳ relative to baseline

    MDS-UPDRS Part Ⅳ (MDS-UPDRS-Ⅳ) scores range from 0 to 24, higher scores mean a worse outcome.

    Measured: 3 and 6 months after surgery

  5. Change in "ON" time and "OFF" time relative to the baseline

    Measured: 3 and 6 months after surgery

  6. Change in motor examination score evaluated using the Movement Disorder Society-sponsored revision of the Unified Parkinson's Disease Rating Scale (MDS-UPDRS) Part Ⅲ with stimulation in "med on" and "med off" states relative to baseline

    MDS-UPDRS Part Ⅲ (MDS-UPDRS-Ⅲ) scores range from 0 to 132, higher scores mean a worse outcome.

    Measured: 6 months after surgery

  7. Change in daily levodopa equivalent dose relative to baseline

    Measured: 3 and 6 months after surgery

  8. Change in the Parkinson's Disease Questionnaire (PDQ-39) score relative to baseline

    The Parkinson's Disease Questionnaire (PDQ-39) is a 39-item questionnaire designed to measure the specific impact of PD on quality of life. Scores range from 0 to 156, higher scores mean a worse outcome.

    Measured: 6 months after surgery

  9. Evaluation of equipment operational performance

    The operational performance of the equipment is evaluated as excellent, good, or poor.

    Measured: Within surgery, 1 month and 3 months after surgery

  10. Incidence of adverse events

    Measured: up to 6 months after surgery

Who may be eligible to take part?

The sponsor lists 4 inclusion and 14 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 18 Aug 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 7 sites in China. 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 Ting Zhang (+86-010-80120666, ting_zhang@lepumedical.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in motor examination score evaluated using the Movement Disorder Society-sponsored revision of the Unified Parkinson's Disease Rating Scale (MDS-UPDRS) Part Ⅲ in "med off" state relative to baseline (time frame: 3 months after surgery). 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 18 Aug 2023.
