Study of BOTOX Injections to Assess Change in Disease Symptoms in Adult Participants With Upper Limb Essential Tremor
United States, Canada174 participantsStarted 2022-04-12
Plain-language summary
Upper limb essential tremor (UL ET) is a movement disorder characterized by postural and/or kinetic tremor. It can cause difficulty with everyday tasks such as writing, pouring, and eating, and patients also experience associated social embarrassment. This study will assess how safe and effective BOTOX is in treating UL ET. Adverse events and change in disease activity will be evaluated.
BOTOX is an investigational drug being developed for the treatment of UL ET. Participants are randomly assigned to 1 of the 4 groups, called treatment arms. Each group receives different treatment. There is 1 in 2 chance that participants will be assigned to placebo. Around 174 participants, aged 18 to 80 years with UL ET will be enrolled in approximately 40 sites in North America.
Participants will receive BOTOX or placebo injections in Cycle 1 and Cycle 2. In Cycle 3, participants will receive unilateral or bilateral BOTOX injections. Each cycle is 12 weeks.
There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, blood tests, checking for side effects and completing questionnaires.

Inclusion Criteria:
* Diagnosis of essential tremor in accordance with modified Tremor Investigation Group (TRIG) criteria as described in the protocol.
* TREDS-Revised Scale (1-4 scale, whole numbers) unilateral score of \>= 3 for the Tremor Disability Scale (TREDS) on any of the 7 unilateral items; no more than a single item score of 1 among the 7 unilateral items in the dominant limb.
* TETRAS activities of daily living (ADL) (recorded on a 0-4 scale, whole numbers) minimum score of \>= 3 on any of the 5 unilateral items; no more than a single item score of \<=1 among the 5 unilateral items in the dominant limb.
* At least one of the following criteria must also be met:
* TETRAS UL score (0-4 scale, with 0.5 increments) of \> 2 in the dominant limb on at least one of the 3 maneuvers OR
* TETRAS Archimedes spiral task score (0-4 scale, with 0.5 increments) of \> 2 in the dominant limb
Exclusion Criteria:
* Any uncontrolled clinically significant medical condition other than the one under study.
* Any medical condition that may put the participant at increased risk with exposure to BOTOX Purified Neurotoxin Complex.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
