About this study

Official title: Botulinum Toxin Type A for Injection of Bilateral Upper Extremity Tremor in Patients With Essential Tremor Using Kinematic Assessment

The primary objective is to study the efficacy of botulinum toxin type A (Xeomin®) injected utilizing kinematically-based injection parameters for the treatment of upper extremity essential tremor (ET). Additional objectives are to study the benefit of kinematic assessment tools in determining injection parameters and to study the composition of tremor using kinematics.

Being tested

What participants receive

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

  • Botulinum toxin type ADrug

    Also called IncobotulinumtoxinA, BoNT-A, Xeomin

Study groups in NCT02551848
Study groupRoleWhat they receive
Essential tremor treatmentExperimentalA serotype of botulinum toxin type A (BoNT-A) that has specificity for cleavage of SYNAPTOSOMAL-ASSOCIATED PROTEIN 25 (SNAP-25). BoNT-A's pharmacological action is to inhibit the release of acetylcholine from the neuromuscular junction. Participants will be treated by BoNT-A injections every 12 weeks over 72 weeks. BoNT-A parameters will be determined solely by biomechanical analysis of tremulous movements in both upper extremity BoNT-A dose will range from 50-300 U per arm
Receives: Drug: Botulinum toxin type A

What is being measured

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

  1. Kinematic tremor severity

    Change from pre to post-BoNT-A treatments in maximum angular tremor amplitude at the wrist in each treated arm. Angular tremor amplitude is one parameter reflecting the vectoral intensity of tremor segmented at each arm joint

    Measured: 72 weeks

Secondary outcomes (3)
  1. Clinical tremor severity

    Improvement in upper limb tremor severity as determined by an increase >8 points on a standardized clinical assessment tool (Fahn-Tolosa-Marin Tremor Assessment Scale) pre and post Xeomin® injection using kinematic-determined injection parameters in both ET upper limbs

    Measured: 72 weeks

  2. Accelerometric kinematic tremor severity

    Change from pre and post-BoNT-A treatments in maximum log-transformed accelerometric tremor amplitude at wrist level (injected limb). Log-transformed accelerometric tremor amplitude is one parameter reflecting the non-vectoral intensity of tremor.

    Measured: 72 weeks

  3. Quality of life measures

    Quality of life for essential tremor questionnaire is used to measure the patient's impression of change due to treatment and its change on their quality of life.

    Measured: 72 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Botulinum toxin type A in people with Essential Tremor, run by Western University, Canada at 1 site in Canada.

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 5 inclusion and 9 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 22 Jun 2020. 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 Canada. 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?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Kinematic tremor severity (time frame: 72 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02551848, which also lists 8 linked publications.

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 22 Jun 2020.
