Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 to 80 years
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • Age 18 to 80 years.
  • Diagnosis of Parkinson's disease, multiple system atrophy, dementia with Lewy bodies, or pure autonomic failure by a neurologist using applicable accepted diagnostic criteria at screening.
  • Neurogenic orthostatic hypotension documented by a standardized active standing test or tilt-table test: after at least 5 minutes of supine rest, a reduction in systolic blood pressure of at least 20 mmHg or diastolic blood pressure of at least 10 mmHg within 3 minutes of standing. A systolic reduction of at least 30 mmHg may support eligibility in participants with supine hypertension.
  • Orthostatic symptoms or fall risk that remain clinically meaningful despite standardized nonpharmacologic management and stable usual medical management.
  • Ability to understand study procedures and provide written informed consent. Participants with mild cognitive impairment require sufficient ability to complete safety assessments and, where required by the ethics committee, involvement of a legally authorized representative.

Who cannot join

  • Orthostatic hypotension primarily attributable to a non-neurogenic or reversible cause, including uncorrected hypovolemia, recent major blood loss, or an active medication-adjustment period.
  • Uncontrolled heart failure, active myocardial ischemia, clinically significant arrhythmia, or other cardiovascular disease making surgery, sedation, or orthostatic testing unsafe.
  • Persistent severe supine hypertension, defined as repeated systolic blood pressure of at least 180 mmHg or diastolic blood pressure of at least 110 mmHg after clinical optimization, that makes stimulation titration unsuitable.
  • Active infection, coagulopathy, inability to interrupt anticoagulant or antiplatelet therapy when required for epidural procedures, or another contraindication to epidural access or implantation.
  • Severe thoracolumbar spinal deformity, prior fusion in the intended lead-placement region, or imaging evidence that makes epidural placement unsuitable.
  • An implanted electronic medical device that is contraindicated or cannot be safely managed with the study stimulation system after specialist assessment.
  • Severe cognitive, psychiatric, or communication impairment that prevents safe participation, symptom reporting, or follow-up.
  • Pregnancy, breastfeeding, or planned pregnancy during study follow-up.

About this study

Official title: A Prospective, Single-Center, Open-Label, Single-Arm Feasibility Study of Lower Thoracic Epidural Spinal Cord Stimulation for Neurogenic Orthostatic Hypotension

Neurogenic orthostatic hypotension is a disabling manifestation of synucleinopathies including Parkinson's disease, multiple system atrophy, dementia with Lewy bodies, and pure autonomic failure. It commonly coexists with supine hypertension and requires individualized management. An implanted thoracic epidural stimulation system improved blood-pressure regulation, standing, and walking in a patient with multiple system atrophy, providing a rationale for further feasibility evaluation. This study evaluates the feasibility, safety, and preliminary hemodynamic response of lower thoracic epidural spinal cord stimulation in participants with symptomatic neurogenic orthostatic hypotension. All participants undergo surgical percutaneous placement of a lower thoracic epidural spinal cord stimulation lead, followed by an externalized trial stimulation period generally lasting no more than 2 weeks. During this period, the acute hemodynamic effect of stimulation is evaluated with a within-participant randomized stimulation ON/OFF comparison during a standardized orthostatic challenge. Participants who meet predefined response and safety criteria receive permanent implantation of the compatible spinal cord stimulation system. After permanent implantation, follow-up occurs at 1, 3, 6, and 12 months to evaluate symptom improvement and safety.

Read the detailed description

The study evaluates a commercially available 16-contact spinal cord stimulation electrode manufactured by PINS Medical, used with its compatible implanted stimulation system. The intended epidural target spans the T10 to T12 vertebral levels. This target is a study hypothesis informed by the rationale of spinal autonomic neuromodulation; it is not an established optimal target for neurogenic orthostatic hypotension. The device model, China registration certificate number, implantable pulse generator model, magnetic resonance imaging conditions, and permitted programming range will be documented before enrollment.

All participants undergo surgical percutaneous placement of a lower thoracic epidural spinal cord stimulation lead, followed by an externalized trial stimulation period generally lasting no more than 2 weeks. During this period, the acute hemodynamic effect of stimulation is evaluated with a within-participant randomized stimulation ON/OFF comparison during a standardized orthostatic challenge. Participants who meet predefined response and safety criteria receive permanent implantation of the compatible stimulation system. After permanent implantation, follow-up occurs at 1 month, 3 months, 6 months, and 1 year to evaluate symptom improvement and safety.

What participants receive

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

  • Lower thoracic epidural spinal cord stimulationDevice

    A 16-contact epidural spinal cord stimulation lead is placed with active contacts covering the intended T10 to T12 region. The lead is externalized for a trial stimulation period generally lasting no more than 2 weeks. During this period, the acute hemodynamic effect of stimulation is assessed using a within-participant randomized stimulation ON/OFF comparison during a standardized orthostatic challenge. Participants meeting predefined response and safety criteria proceed to permanent implantation of the compatible spinal cord stimulation system. Initial programming uses individualized low-to-high titration within the device instructions for use: frequency 5 to 50 Hz and pulse width 200 to 500 μs. Amplitude increases from a subperception or lowest perceptible level until hemodynamic benefit, intolerable symptoms, or the device-specific permitted limit is reached.

What is being measured

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

  1. Difference in lowest systolic blood pressure during standardized orthostatic challenge with stimulation ON versus OFF

    During the externalized trial stimulation period, each participant completes standardized orthostatic challenges under randomized stimulation ON and OFF conditions. After at least 5 minutes of supine rest, blood pressure is measured continuously from the start of standing until 10 minutes of standing or until a prespecified stopping criterion is met. The lowest systolic blood pressure in each condition is identified. The outcome is the difference in lowest systolic blood pressure during stimulation ON versus OFF, calculated as ON minus OFF, in mmHg. A positive value indicates a higher lowest systolic blood pressure with stimulation ON. The ON and OFF order is randomized within each participant.

    Measured: During the externalized trial stimulation period, generally no more than 2 weeks after lead placement

Secondary outcomes (7)
  1. Feasibility of the trial-to-implant pathway

    Proportion of enrolled participants who complete the externalized trial stimulation period, meet predefined trial success criteria, receive permanent implantation of the spinal cord stimulation system, and complete scheduled follow-up assessments. Trial success is defined as at least one standardized orthostatic assessment during trial stimulation showing either an increase of at least 10 mmHg in the lowest systolic blood pressure with stimulation ON versus OFF, or an increase of at least 30% in orthostatic tolerance time, together with participant-reported overall symptom improvement and no device- or procedure-related serious adverse event.

    Measured: From enrollment through 12 months after permanent implantation

  2. Orthostatic blood-pressure response

    Change in systolic and diastolic blood pressure from supine baseline during standardized orthostatic challenge, time to lowest blood pressure, and occurrence of systolic blood pressure below 90 mmHg within 10 minutes of standing. Blood pressure is measured after at least 5 minutes of supine rest and continuously from standing onset until 10 minutes of standing or until a prespecified stopping criterion is met. A greater increase in blood pressure from supine baseline indicates better orthostatic blood-pressure response.

    Measured: Baseline; externalized trial stimulation period; 1, 3, 6, and 12 months after permanent implantation

  3. Orthostatic tolerance time

    Duration of tolerated standing during the standardized orthostatic challenge, up to 10 minutes. The reason for early termination, including presyncope, syncope, intolerable symptoms, or safety concern, is recorded. A longer tolerated standing time indicates better orthostatic tolerance. Participants who complete 10 minutes of standing without early termination are assigned the maximum value of 10 minutes.

    Measured: Baseline; externalized trial stimulation period; 1, 3, 6, and 12 months after permanent implantation

  4. Orthostatic symptom burden

    Change in score on a licensed or linguistically validated Chinese orthostatic hypotension symptom measure. The scale range and direction of possible scores will be provided once the instrument is confirmed. A decrease in score indicates improvement in orthostatic symptom burden if the selected instrument uses a higher score to indicate worse symptoms.

    Measured: Baseline; externalized trial stimulation period; 1, 3, 6, and 12 months after permanent implantation

  5. Patient Global Impression of Change

    Participant-rated global change in orthostatic symptoms. Participants rate their overall change in orthostatic symptoms compared with baseline using a validated Patient Global Impression of Change scale. The scale typically ranges from 1 to 7, with 1 indicating very much improved and 7 indicating very much worse, or according to the validated version used.

    Measured: Externalized trial stimulation period; 1, 3, 6, and 12 months after permanent implantation

  6. Supine hypertension and ambulatory blood pressure

    Supine blood pressure after 5 minutes of rest and prespecified metrics from 24-hour ambulatory blood-pressure monitoring, including nighttime blood pressure where available.Metrics may include mean 24-hour, daytime, and nighttime systolic and diastolic blood pressure, as well as the proportion of participants with supine systolic blood pressure at least 180 mmHg or diastolic blood pressure at least 110 mmHg. A lower supine blood pressure indicates less severe supine hypertension.

    Measured: Baseline; externalized trial stimulation period; 1, 3, 6, and 12 months after permanent implantation

  7. Device-, procedure-, and stimulation-related adverse events

    Number and proportion of participants with adverse events and serious adverse events, classified by severity, relationship to device or procedure, action taken, and outcome. Events are assessed from consent through 12 months after permanent implantation and are coded according to the applicable regulatory and institutional standards.

    Measured: From consent through 12 months after permanent implantation
