About this study

Official title: Prospective Study of Constant Current Versus Constant Voltage Deep Brain Stimulation in Patients with Parkinson's Disease

To compare the efficacy, programming burden, power consumption, and physicians' and patients' satisfaction between current mode and voltage mode of deep brain stimulation in each period one year after surgery.

Read the detailed description

This is a randomized, parallel controlled, multi-center study to compare the efficacy, programming burden, power consumption, and physicians' and patients' satisfaction between current mode and voltage mode of deep brain stimulation in each period one year after surgery. Participants will be followed for up to 12 months. Approximately 180 PD participants will be recruited from up to 14 sites. Participants will be randomized to current mode or voltage mode after DBS surgery and be comprehensively assessed at baseline and follow up according to the protocol developed.

Being tested
Constant current (CC) subthalamic nucleus deep brain stimulation, Constant voltage (CV) subthalamic nucleus deep brain stimulation

What participants receive

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

  • Constant current (CC) subthalamic nucleus deep brain stimulationOther

    For subjects who have decided to undergo STN-DBS surgery and meet the inclusion criteria, the constant current (CC) mode is selected as the original electronic modality one week after surgery. Regardless of any changes in programming parameters over the following year, the constant current (CC) mode will be maintained.

  • Constant voltage (CV) subthalamic nucleus deep brain stimulationOther

    For subjects who have decided to undergo STN-DBS surgery and meet the inclusion criteria, the constant voltage (CV) mode is selected as the original electronic modality one week after surgery. Regardless of any changes in programming parameters over the following year, the constant voltage (CV) mode will be maintained.

What is being measured

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

  1. The change rate of MDS-UPDRS III

    MDS-UPDRS III is the motor examination section of the MDS-UPDRS (Movement Disorder Society-sponsored revision of the Unified Parkinson's Disease Rating Scale), completed by the evaluator, providing an objective assessment of motor symptoms in patients with Parkinson's disease. MDS-UPDRS III ranges from 0-132. The change rate of MDS-UPDRS III in the Stim-On/Med-On state from baseline to 6 months after surgery will be collected. Positive indicates improvement.

    Measured: from baseline to 6 months after surgery

Secondary outcomes (9)
  1. MDS-UPDRS I

    MDS-UPDRS I is the non-motor experiences of daily living section of the MDS-UPDRS (Movement Disorder Society-sponsored revision of the Unified Parkinson's Disease Rating Scale). Subsection IA is evaluated by the researcher based on all relevant information provided by the patient or their caregiver regarding certain symptoms. Subsection IB is completed by the patient, with assistance from the caregiver if needed, but it must not be completed by the researcher. The change rate of MDS-UPDRS I from baseline to 6 months after surgery will be collected.

    Measured: from baseline to 6 months after surgery

  2. MDS-UPDRS II

    MDS-UPDRS II is the motor experiences of daily living section of the MDS-UPDRS (Movement Disorder Society-sponsored revision of the Unified Parkinson's Disease Rating Scale) and is a self-reported questionnaire completed by the patient. The change rate of MDS-UPDRS II from baseline to 6 months after surgery will be collected.

    Measured: from baseline to 6 months after surgery

  3. MDS-UPDRS IV

    MDS-UPDRS IV is the motor complications section of the MDS-UPDRS (Movement Disorder Society-sponsored revision of the Unified Parkinson's Disease Rating Scale). This section is rated by the evaluator, combining information provided by the patient with the evaluator's clinical observation and judgment to generate a comprehensive score. The change rate of MDS-UPDRS IV from baseline to 6 months after surgery will be collected.

    Measured: from baseline to 6 months after surgery

  4. Clinical Global Impression (CGI)

    The Clinical Global Impression (CGI) is a global assessment scale initially designed by the World Health Organization (WHO) for use in IPSS research to evaluate clinical efficacy. It provides an overall measure of treatment outcomes.

    Measured: from baseline to 6 months after surgery

  5. Physician satisfaction feedback

    The programming physician completes a custom-made questionnaire based on their subjective judgment.

    Measured: from baseline to 6 months after surgery

  6. Patient satisfaction feedback

    The patient completes a custom-made questionnaire based on their subjective judgment.

    Measured: from baseline to 6 months after surgery

  7. power consumption

    The total power consumption of the patient's IPG between visits is calculated. During follow-up, device logs are uploaded from the charging equipment to the database. The raw data is then retrieved from the database.

    Measured: from baseline to 6 months after surgery

  8. impecence

    Use the programming device to measure impedance on all contacts of the IPG.

    Measured: from baseline to 6 months after surgery

  9. Adverse effects

    Record any adverse events and serious adverse events during the study period.

    Measured: from baseline to 12 months after surgery

Questions about this trial

What is this clinical trial studying?

A study testing Constant current (CC) subthalamic nucleus deep brain stimulation and Constant voltage (CV) subthalamic nucleus deep brain stimulation in people with Parkinson's Disease (PD), run by Xuanwu Hospital, Beijing at 1 site in China.

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 3 inclusion and 7 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: looking for participants now, as of the sponsor's last update on 19 Dec 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site 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?

This study is still under way. Results are not available in the source record yet.

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

Contact Shanshan Mei (+86 13426263236, sophy33@163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The change rate of MDS-UPDRS III (time frame: from baseline to 6 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 19 Dec 2024.
