| Primary | Change From Baseline to Week 12 on the TETRAS Composite Outcome Score as Summarized by Each Dose of JZP385 and Placebo | Change from baseline to week 12 | The TETRAS composite outcome score is the sum of modified items 1 - 11 of the TETRAS-ADL subscale and modified items 6 - 7 of the TETRAS-PS. The TETRAS-ADL subscale is a patient-rated scale administered by a trained interviewer that assesses the impact of tremor on day-to-day functioning, such as eating, drinking, dressing, and other fine motor skills. The TETRAS-PS is a clinical rating scale that quantifies tremor in the head, face voice, limbs and trunk. Items 6 (drawing an Archimedes spiral using left and right hands) and 7 (handwriting) of the TETRAS-PS evaluate the impact of upper limb tremor on performance. Each item from the modified subscales ranges from 0 - 3, with 0 representing normal or slightly abnormal and 3 representing severely abnormal. The sum of the 14 items provides the TETRAS composite outcome score, which ranges from 0 - 42, with higher scores representing more severe ET. |
| Secondary | Percentage of Participants Who Improved (≥ 1-Point Improvement) From Baseline to Week 12 on the Clinical Global Impression- Severity Scale (CGI-S) | Change from baseline to week 12 | The CGI-S is a 5-point Likert-type rating scale that a qualified medical personnel (ie, a clinician)will use to rate the severity of the participants' ability to function due to their ET. The responses to this scale range from 1 (no limitations) to 5 (severe). |
| Secondary | Proportion of Participants Reported as Much Improved on the Clinical Global Impression of Change (CGI-C) at Week 12 | Week 12 | The CGI-C is a 5-point Likert-type rating scale that a qualified medical personnel (ie, a clinician) will use to rate the change in severity of the participants' ability to function due to their ET since baseline. The responses to this scale range from 1 (Much improved) to 5 (Much worse). |
| Secondary | Proportion of Participants Reported as Much Improved on the Patient Global Impression of Change (PGI-C) at Week 12 | Change from baseline to week 12 | The PGI-C is a 5-point Likert-type rating scale that participants use to rate the change in severity of their ability to function due to ET since baseline. The responses to this scale range from 1 (Much improved) to 5 (Much worse). |
| Secondary | Change From Baseline to Week 12 on the TETRAS-ADL Subscale as Summarized by Each Dose of JZP385 and Placebo | Change from baseline to week 12 | The TETRAS-ADL subscale is a patient-rated scale of the impact of tremor on day-to-day functioning administered by a trained interviewer. The TETRAS-ADL subscale directly measures how a patient functions by assessing activities impacted by tremor, such as eating and drinking, dressing and personal hygiene, carrying items and fine motor skills. The TETRAS-ADL has 12 items, and each item is rated on a 0 (normal) to 4 (severe) scale with a total score ranging from 0 to 48. A higher score represents more severe ET. |
| Secondary | Change From Baseline to Week 12 on the TETRAS-PS Subscale as Summarized by Each Dose of JZP385 and Placebo | Change from baseline to week 12 | The TETRAS-PS is a clinical rating scale performed by a blinded rater that quantifies tremor in the head, face, voice, limbs, and trunk. Each item will be rated on a scale of 0 (normal) to 4 (severe). The sum of the individual scores provides the overall score, ranging from 0 to 64, with higher scores representing more severe ET. |
| Secondary | Change From Baseline to Week 12 on the Upper Limb Score (Item 4) of the TETRAS-PS as Summarized by Each Dose of JZP385 and Placebo | Change from baseline to week 12 | Item 4 of the TETRAS-PS measures upper limb tremor, and includes 3 maneuvers for each arm that assess postural and kinetic tremor. Each item is rated on a scale of 0 (normal) to 4 (severe) in 0.5-point increments. The total score is the sum of each of the 6 items and ranges from 0 to 24, with higher scores representing more severe ET. The TETRAS-PS is performed by a blinded rater. |
| Secondary | Change From Baseline to Week 12 on the TETRAS Total Score, as Summarized by Each Dose of JZP385 and Placebo. | Change from baseline to week 12 | The TETRAS total score is the sum of the scores of the full TETRAS-ADL and TETRAS-PS subscales. Each item is rated on a 0 (normal) to 4 (severe) scale, and total scores range from 0 to 112, with higher scores representing more severe ET. The TETRAS-PS is performed by a blinded rater. |
| Secondary | Change From Baseline to Week 12 on the Quality of Life in Essential Tremor Questionnaire (QUEST) as Summarized by Each Dose of JZP385 and Placebo | Change from baseline to week 12 | The Quality of Life in Essential Tremor Questionnaire (QUEST) was developed to specifically assess the impact of ET on health-related quality of life. The QUEST is a 30-item questionnaire comprising 5 subscales (physical, psychosocial, communication, hobbies/leisure, and work/finance). Each item is rated by frequency on a scale from 0 (never) to 4 (always). Each dimension had been standardized to a range of 0 to 100 with higher scores indicating greater dissatisfaction or disability due to ET. |
| Secondary | Change From Baseline to Week 12 on the Essential Tremor Embarrassment Assessment (ETEA) Score A as Summarized by Each Dose of JZP385 and Placebo | Change from baseline to week 12 | The Essential Tremor Embarrassment Assessment (ETEA) is a participant-rated questionnaire administered by a health care provider or researcher that contains 14-items assessing embarrassment related to tremor. For Score A, participants provide a simple response (disagree or agree) to each of the 14-items, the sum of which yields an initial score range = 0 to 14. Higher scores indicate greater embarrassment |
| Secondary | Change From Baseline to Week 12 on the Essential Tremor Embarrassment Assessment (ETEA) Score B as Summarized by Each Dose of JZP385 and Placebo | Change from baseline to week 12 | The Essential Tremor Embarrassment Assessment (ETEA) is a participant-rated questionnaire administered by a health care provider or researcher that contains 14-items assessing embarrassment related to tremor. For Score B, participants provide a more nuanced response to each question on a 0 to 5 point Likert scale ranging from disagree (0) to agree strongly (5). The sum of the nuanced responses yields a second score (range = 0 to 70). Higher scores indicate greater embarrassment |
