About this study

Official title: Using Time Varying Non-Invasive Neuromodulation to Improve Neurovascular Status in Parkinson's Disease

This study is a single-site, double-blinded, placebo-controlled, randomized clinical trial designed to elucidate mechanism(s) of action for symptomatic benefits observed in Parkinson's disease (PD) patients treating twice daily time-varying caloric vestibular stimulation treatment using a solid-state device. Study participants will self-administer treatments in the home setting over a period of 12 weeks. Changes in cerebral blood flow perfusion, cerebrovascular reactivity and functional connectivity between the pre-treatment baseline and the end of the treatment period will be monitored and will be compared to changes in validated standardized clinical measures of motor and non-motor symptoms in PD. The durability of effects will be evaluated at a post-treatment assessment conducted five weeks after treatment cessation.

Read the detailed description

A double-blinded, placebo-controlled randomized trial will explore the effects of time-varying caloric vestibular stimulation (tvCVS) treatments on changes in biomarkers of neurovascular status (i.e. cerebral blood flow perfusion and cerebrovascular reactivity) as well as their relationship to clinical endpoints. Participants will be randomly allocated in a 1:1 ratio using block randomization by the clinical site. Participants will be trained in the clinic to self-administer device treatment and then will continue to self-administer the ~19-minute treatments twice daily for 12 weeks in the home. Individual stimulation sessions will be spaced a minimum of 1 hour apart. Outcome measures will be administered at the baseline, the end of the 12-week treatment period and at 5 weeks post-treatment. Study participants will continue to take their approved Parkinson's disease (PD) medications throughout the study and will maintain patterns of usage throughout.

Previous evidence for efficacy demonstrated therapeutic gains as an adjuvant for standard of care treatment. Consistent with these observations, all outcome measures will be evaluated when study participants are in the on-medication state and at the same time relative to the last dose of anti-Parkinsonian medication across all assessments. Clinical measures will be captured at the baseline, at the end of treatment period, and again five weeks after cessation of treatment. Most of the planned clinical measures including the Movement Disorder Society Unified Parkinson's Disease Rating Scale (MDS-UPDRS) parts I, II, and IV, the Non-Motor Symptom Scale for PD (NMSS), the Montreal Cognitive Assessment (MoCA), the Parkinson's Anxiety Scale, the Geriatric Depression Scale, the Epworth Sleepiness Scale, and the Functional Assessment of Chronic Illness Therapy- Fatigue are suitable for virtual collection. Case report forms (CRFs) for the patient reported outcomes will be provided to study participants via standard mail. At the end of each virtual visit, participants will be asked to complete these forms and bring them to the clinic the next day when they come for their in-clinic visit. In the case where an in-clinic visit may not be possible, participants will be asked to show completed forms to the coordinator via the telemedicine platform to confirm completeness, and forms will be collected at the next in-person visit or can be mailed in by the participant.

The full MDS- UPDRS part III and the Timed Up and Go will be administered in the clinic. However, a modified MDS-UPDRS part III (excluding items related to rigidity or postural instability) will also be administered through the telemedicine platform. This measure will serve as backup for cases where participants may be unable to come into the clinic for regularly scheduled assessment (e.g. due to COVID-19 containment measures).

What is being measured

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

  1. Neuroimaging

    Brain data will be acquired with Siemens MAGNETOM Skyra 3T MRI - range measured by statistically significant change in cerebral blood flow (CBF) measured in units of mL/100g/min

    Measured: Baseline

  2. Neuroimaging

    Brain data will be acquired with Siemens MAGNETOM Skyra 3T MRI - range measured by statistically significant change in cerebral blood flow (CBF) measured in units of mL/100g/min

    Measured: Week 12

  3. Neuroimaging

    Brain data will be acquired with Siemens MAGNETOM Skyra 3T MRI - range measured by statistically significant change in cerebral blood flow (CBF) measured in units of mL/100g/min

    Measured: Week 17

  4. Transcranial Doppler Sonography

    Non-invasive ultrasound used to examine blood circulation within the brain - range measured by statistically significant change in mean cerebral blood flow velocity (cm/s)

    Measured: Baseline

  5. Transcranial Doppler Sonography

    Non-invasive ultrasound used to examine blood circulation within the brain - range measured by statistically significant change in mean cerebral blood flow velocity (cm/s)

    Measured: Week 12

Secondary outcomes (8)
  1. MDS-Unified Parkinson's Disease Rating Scale

    Used to follow the longitudinal course of symptoms of Parkinson's disease - Each parkinsonian sign or symptom is rated on a 5-point Likert-type scale (ranging from 0 to 4), with higher scores indicating more severe impairment. The maximum total UPDRS score is 199, indicating the worst possible disability from PD

    Measured: Baseline, Week 12, Week 17

  2. Timed Up and Go Test

    To determine fall risk and measure the progress of balance, sit to stand and walking (ranging from ≤10 seconds as normal to 30 seconds as high fall risk).

    Measured: Baseline, Week 12, Week 17

  3. Montreal Cognitive Assessment

    Cognitive screening test - range from zero to 30, with a score of 26 and higher generally considered normal.

    Measured: Baseline, Week 12, Week 17

  4. Non-Motor Symptom Scale

    Scale to assess a wide range of non-motor symptoms in patients with Parkinson's disease - 30-item rater-based scale to assess a wide range of non-motor symptoms in patients with Parkinson's disease (PD). The NMSS measures the severity and frequency of non-motor symptoms across nine dimensions - the total NMSQuest score significantly increased with disease severity and duration meaning that the number of individual non-motor symptoms reported by our patients increases as the disease progresses.

    Measured: Baseline, Week 12, Week 17

  5. Geriatric Depression Scale

    A self-report measure of depression in older adults - Scores of 0-4 are considered normal, depending on age, education, and complaints; 5-8 indicate mild depression; 9-11 indicate moderate depression; and 12-15 indicate severe depression.

    Measured: Baseline, Week 12, Week 17

  6. Parkinson's Anxiety Scale

    Anxiety assessment - The PAS is a 12-item observer or patient-rated scale with three subscales, for persistent, episodic anxiety and avoidance behavior - There is a maximum total score of 48. Higher scores indicate great experiences of anxiety.

    Measured: Baseline, Week 12, Week 17

  7. Epworth Sleepiness Scale

    A self-administered questionnaire to assess the daytime sleepiness - The ESS score (the sum of 8 item scores, 0-3) can range from 0 to 24. The higher the ESS score, the higher that person's average sleep propensity in daily life (ASP), or their 'daytime sleepiness'.

    Measured: Baseline, Week 12, Week 17

  8. Functional Assessment of Chronic Illness Therapy - Fatigue -

    A tool to help manage chronic illness - The responses to the 13 items on the FACIT fatigue questionnaire are each measured on a 4-point Likert scale. Thus, the total score ranges from 0 to 52. High scores represent less fatigue

    Measured: Baseline, Week 12, Week 17
