| Change From Baseline in The Essential Tremor Rating Assessment Scale (TETRAS) Performance Subscale Item 4 (Upper Limb) Total Score on Day 91 in the Monotherapy Cohort | TETRAS is a clinical evaluation of essential tremor. The TETRAS performance subscale upper limb tremor score is a component of TETRAS. For the TETRAS Performance Subscale Item 4 (upper limb), three maneuvers/assessments were to be completed for both arms, first for the right arm and then for the left, specifically Item 4a, limbs extended forward maneuver (postural tremor), Item 4b, wing-beating [elbows flexed] maneuver (postural tremor), and Item 4c finger-nose-finger maneuver (kinetic tremor). Each assessment is rated on a 0 to 4 scale of severity in 0.5-point increments, with higher scores indicating more severe tremor. The Performance Subscale Item 4 (upper limb) total score range for a given side (left or right) is 0 to 12, and for both sides combined is 0 to 24. A negative change from baseline indicates improvement. Mixed model for repeated measures (MMRM) was used for the analysis. | Baseline, Day 91 |
| Measure | Description | Time Frame |
|---|---|---|
| Change From Baseline in TETRAS Activities of Daily Living (ADL) Composite Score in the Monotherapy Cohort | TETRAS ADL Subscale (items 1-12) assesses how ET affects typical ADL (speech, eating, drinking, dressing, personal hygiene, writing, occupational impairment, social impact, activities affected by UL tremor). TETRAS ADL composite score comprises Items 1-11 of ADL Subscale (Item 1: speech impairment; Item 10: occupational impairment; remaining 9 items: impairment in activities affected by UL tremor) and Item 6 of Performance Subscale (spiral drawing). Each of individual item is rated on a scale from 0 (normal activity) to 4 (severe abnormality); responses of 0 & 1 in TETRAS ADL Subscale Items 1 to 11 were collapsed such that scale is 0 (normal/slightly abnormal), 1 (mildly abnormal), 2 (moderately abnormal), and 3 (severely abnormal). Performance Subscale Item 6 responses were collapsed with responses having 0.5 point increments grouped with next higher integer response. ADL composite score range is 0 to 39. Higher score=greater abnormality, negative change=improvement. |

Inclusion Criteria:
Diagnosis of ET, as defined by all of the following criteria:
Absence of other neurological signs, such as dystonia, ataxia, or parkinsonism, isolated focal tremors (eg, voice, head), task- and position-specific tremors, sudden tremor onset, or evidence of stepwise deterioration of tremor.
Participant has the following:
Participant has a baseline TETRAS ADL Subscale score of at least 20 at Screening.
Willing to discontinue medications taken for the treatment of ET except propranolol at least 14 days or 5 half-lives (whichever is longer) prior to receiving the investigational product (IP). Medications taken for the treatment of ET that were discontinued prior to receiving IP may be resumed following Day 97. Participants in the adjunct therapy cohort must be on a stable dose of propranolol (maximum total daily propranolol dose up to 320 mg allowed) for the treatment of ET from 3 months prior to Screening through Day 97 of the study.
Participant is willing to limit use of alcohol to 2 units per day for males and 1 unit per day for females starting at least 1 week prior to Day 1 and through Day 97 of the study.

A total of 160 participants were planned for the study, of which 147 participants were randomized. Out of 147, 1 participant was randomized in error but was not assigned in any of the treatment group. This participant did not receive any treatment, therefore only146 participants received IP.
Participants were enrolled at 51 investigative sites in the United States from 05 Jan 2022 to 16 May 2024.
