About this study

The purpose of this Phase I open label study is to evaluate longer term tolerability and potential effectiveness of transcranial ultrasound in people with tremor as a results of Parkinson's Disease or Essential Tremor.

Read the detailed description

This study is designed to evaluate the safety and efficacy of focused ultrasound in patients with Parkinson's Disease or Essential Tremor characterized by tremor. The safety of this protocol will be closely monitored and data will be used to determine whether any significant safety issues exist when using focused ultrasound. Adverse events will be noted whenever they occur but will be recorded at the time of the procedure and throughout routine follow-ups, which will persist weekly throughout the duration of the active study protocol. Patients deemed potentially appropriate candidates for focused ultrasound therapy will be treated with 8 sessions of transcranial ultrasound, each of which consists of 10 to 30 minutes of active administration. Clinical and safety outcome measures will be obtained throughout and after completion of the study protocol.

Being tested

What participants receive

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

  • Focused UltrasoundDevice

    The DWL Doppler ultrasound device enables visual and auditory waveform confirmation of the middle cerebral artery, and optical tracking technology (e.g., AntNeuro Visor2™ system) may be used in tandem with the Brainsonix ultrasound device to track a patient's brain in virtual space as well as their physical location, thereby ensuring accurate placement.

Study groups in NCT05475340
Study groupRoleWhat they receive
ExperimentalExperimentalParticipants will undergo ten to thirty minutes of transcranial ultrasound treatment. The sanitation device will be aimed at the hypothalamus. Targeting will include reference to scalp fiducials based on the obtained MRI; confirmation of target accuracy will either be obtained by Doppler waveform confirmation or optical tracking technology which co-registers patient neuroimaging with real space.
Receives: Device: Focused Ultrasound

What is being measured

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

  1. Essential Tremor Rating Assessment Scale (TETRAS)

    The Essential Tremor Rating Assessment Scale was developed by the Tremor Research Group to quantify essential tremor severity and its impact on activities of daily living.

    The ADL section of TETRAS has 12 items, each rated 0, 1, 2, 3 or 4. The maximum total score is 48. Item 1 addresses speech; item 10 addresses occupational impairment; and item 12 assesses social impact. The other 9 items assess activities that are affected primarily by upperweighting of lower limb tremor in the total performance score.

    Measured: Baseline

  2. Essential Tremor Rating Assessment Scale (TETRAS)

    The Essential Tremor Rating Assessment Scale was developed by the Tremor Research Group to quantify essential tremor severity and its impact on activities of daily living.

    The ADL section of TETRAS has 12 items, each rated 0, 1, 2, 3 or 4. The maximum total score is 48. Item 1 addresses speech; item 10 addresses occupational impairment; and item 12 assesses social impact. The other 9 items assess activities that are affected primarily by upperweighting of lower limb tremor in the total performance score.

    Measured: Through Completion of Study (Average time 8-weeks)

Secondary outcomes (4)
  1. 9 Hole Pegboard Task (9 HPT)

    A validated assessment for fine motor skills, the 9-HPT involves having a participant move 9 pegs individually from starting position to 9 separate peg-holes, as quickly as possible, and to immediately return the 9 pegs to the starting position upon filling the final peg-hole. This is performed separately for each hand. The score is the time (seconds/milliseconds) that it takes to complete the task, recorded separately for dominant and non-dominant hands. The minimum detectable change is 2.6 seconds for the dominant hand and 1.3 seconds for the non-dominant hand.

    Measured: Baseline

    A validated assessment for fine motor skills, the 9-HPT involves having a participant move 9 pegs individually from starting position to 9 separate peg-holes, as quickly as possible, and to immediately return the 9 pegs to the starting position upon filling the final peg-hole.

The minimum detectable change is 2.6 seconds for the dominant hand and 1.3 seconds for the non-dominant hand.

    Measured: Through Completion of Study (Average time 8-weeks)

  3. Parkinson's Activities of Daily Living Scale (PAD-L)

    The Parkinson's Activities of Daily Living Scale is a self-report activities of daily living scale designed to assess difficulties in daily activities due to symptoms of Parkinson's Disease.

    Measured: Baseline

  4. Parkinson's Activities of Daily Living Scale (PAD-L)

    The Parkinson's Activities of Daily Living Scale is a self-report activities of daily living scale designed to assess difficulties in daily activities due to symptoms of Parkinson's Disease.

    Measured: Through Completion of Study (Average time 8-weeks)

Questions about this trial

What is this clinical trial studying?

A Early Phase 1 study testing Focused Ultrasound in people with Tremor and Parkinson Disease, run by Neurological Associates of West Los Angeles at 1 site in United States.

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 12 inclusion and 13 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 26 Jan 2023. 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 United States. 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.

What does this phase mean?

Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

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 Rama Surya (3108295968 ext. 214, jsurya@theneuroassociates.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Essential Tremor Rating Assessment Scale (TETRAS) (time frame: 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 26 Jan 2023.
