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

  • Patients with task-dependent essential tremor in upper limb. Tremor is present during at least one of the study functional tasks i. pointing task (touch between nose and a pen held 2 ft. in front. ii. pouring task (cup: pouring water out/in). iii. feeding task (weighted fork from plate on table to mouth). iv. string instrument bowing or holding instrument in static position. v. computer mouse (simple vertical or horizontal movements).
  • Patients must be capable of performing informed consent.
  • Patients on stable medications for treatment of task-dependent essential tremor for 1 month prior to study entry and maintain them throughout the study.
  • Patients previously treated with BoNT of any type must have occurred no sooner than 12 weeks prior to study entry.

Who cannot join

  • Patients with no presence of tremor during study functional tasks.
  • Presence of tremor during the functional task is below minimum amplitude required to be considered for injection based upon investigator's clinical judgment.
  • Patients with unstable medical conditions or psychiatric conditions.
  • Patients with a medical condition that precludes them from receiving BoNT injections.
  • Pregnant women, or premenopausal women not willing to use contraceptive measures throughout the duration of the study.
  • Lithium, Valproic acid, Amiodarone, typical and atypical neuroleptics. Exposure to other than the listed tremorogenic or potentially tremorogenic drugs is allowed only if, in the opinion of the investigator, this will not interfere with the study drug evaluations.

About this study

Official title: A Placebo-controlled, Double-blind, Randomized, Cross Over Pilot Study of the Efficacy and Tolerability of Abobotulinum Toxin A (Dysport) as a Treatment for Task-dependent Upper Limb Tremor

Task-dependent upper limb tremor is a disorder that frequently impairs patients' function and quality of life. Few studies exist that quantify the improvements in motor performance and disability with botulinum toxin (injections). The study team aims to perform an exploratory pilot trial using toxin Type A (Dysport) in 25 patients with task-dependent upper limb tremor, to refine quantitative measures of performance using blinded video analysis, demonstrate efficacy and tolerability of injections, and provide power calculations for a potential future multi-centered double blinded clinical trial.

What is being measured

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

  1. Patient's Impression of Change

    The principal outcome measure will be patient's impression of change using visual analog scale. Visual Analog Scale (VAS) 100 point scale from 0 (no improvement) to 100 (normal use).

    Measured: Week 6

  2. Patient's Impression of Change

    The principal outcome measure will be patient's impression of change using visual analog scale. Visual Analog Scale is a 100 point scale from 0 (no improvement) to 100 (normal use).

    Measured: Week 18

Secondary outcomes (1)
  1. Physician Global Impression of Change

    Physician global impression of change is measured by using a visual analog scale. The CGI using a VAS is rated on a 100-point scale, with the severity of illness scale using a range of responses from 0 (no improvement) through to 100 (normal use).illness scale using a range of responses from 1 (normal) through to 7 (amongst the most severely ill patients).

    Measured: Week 6

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Abobotulinum toxin A in people with Tremor, Limb, run by David M. Simpson 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 4 inclusion and 6 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 25 Feb 2021. 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. Some participants in this study may receive a placebo. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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

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 Mary-Catherine George (212-241-0784, Mary-Catherine.George@mssm.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Patient's Impression of Change (time frame: Week 6). 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?

On the ClinicalTrials.gov record for NCT03136341, which also lists 14 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 25 Feb 2021.
