ListOutcomeTime frameDescription
PrimaryPart A: Change From Baseline in Accelerometer-based Kinesia Kinetic Tremor Combined Score at Day 7Baseline (Day 1) and Day 7 (8 hours postdose)
The accelerometer-based Kinesia kinetic tremor combined score is the sum of Kinesia kinetic tremor scores across both sides of the body. Tremor is measured using a motion sensor that transmits raw data to a computer where it converts the tremor amplitude to a Kinesia score of 0 to 4 based on validated algorithms; the total score ranges from 0 to 8, higher scores indicate more severe tremor. A negative change from Baseline indicates improvement.
PrimaryPart B: Change From Randomization in Accelerometer-based Kinesia Kinetic Tremor Combined Score at Day 14Randomization (Day 8, predose) and Day 14 (predose)
The accelerometer-based Kinesia kinetic tremor combined score is the sum of Kinesia kinetic tremor scores across both sides of the body. Tremor is measured using a motion sensor that transmits raw data to a computer where it converts the tremor amplitude to a Kinesia score of 0 to 4 based on validated algorithms; the total score ranges from 0 to 8, higher scores indicate more severe tremor. A negative change from Randomization indicates improvement.
PrimaryPart C: Change From Baseline in the Accelerometer-based Kinesia Upper Limb Tremor Combined Score at Day 15Baseline (Day 1) and Day 15
The accelerometer-based Kinesia upper limb total score is the sum of the individual item scores across both sides of the body. The individual items included forward outstretched postural tremor (FOPT), lateral "wing beating" postural tremor (LWBPT), and kinetic tremor (KT) scores from both sides of the body. Each upper limb individual item question score for each side of the body ranges from 0 to 4. The Kinesia upper limb total score ranges from 0 to 24, with higher scores indicating more tremors/greater tremor amplitude. A negative change from Baseline indicates improvement.
SecondaryPart A: Change From Baseline in Kinesia Upper Limb Total Score at Day 7Baseline (Day 1) and Day 7 (8 hours postdose)
The accelerometer-based Kinesia upper limb total score is the sum of Kinesia kinetic tremor scores across both sides of the body. The individual items included forward outstretched postural tremor (FOPT), lateral "wing beating" postural tremor (LWBPT), and kinetic tremor (KT) scores from both sides of the body. Each upper limb individual item question score for each side of the body ranges from 0 to 4. The Kinesia upper limb total score ranges from 0 to 24, with higher scores indicating more tremors/greater tremor amplitude. A negative change from Baseline indicates improvement.
SecondaryPart A: Change From Baseline in Kinesia Upper Limb Individual Item Score at Day 7Baseline (Day 1) and Day 7 (8 hours [hr] postdose [pd])
The accelerometer-based Kinesia upper limb total score is the sum of Kinesia kinetic tremor scores across both sides of the body. The individual items included forward outstretched postural tremor (FOPT), lateral "wing beating" postural tremor (LWBPT), and kinetic tremor (KT) scores from both sides of the body. Each upper limb individual item question score for each side of the body ranges from 0 to 4, with higher scores indicating more tremors/greater tremor amplitude. The Kinesia upper limb total score ranges from 0 to 24, with higher scores indicating more tremors/greater tremor amplitude. A negative change from Baseline indicates improvement.
SecondaryPart A: Change From Baseline in the Tremor Research Group (TRG) Essential Tremor Rating Assessment Scale (TETRAS) Upper Limb Total Score at Day 7Baseline (Day 1) and Day 7 (8 hours postdose)
The TETRAS performance subscale upper limb total score is the sum of the TETRAS individual item scores from both sides of the body. The TETRAS individual item score included TETRAS Performance Subscale item 4a, 4b and 4c scores \[4a: forward outstretched postural tremor (FOPT) and 4b: lateral "wing beating" postural tremor (LWBPT) scores and 4c: Kinetic tremor (KT) score\] from both sides of the body. Each individual item score ranges from 0 to 4; The total upper limb score ranges from 0 to 24, higher scores indicate more severe tremor. A negative change indicates improvement.
SecondaryChange From Baseline in the TETRAS Upper Limb Individual Items (Performance Subscale Items 4a, 4b, or 4c) Scores at Day 7Baseline (Day 1) and Day 7 (8 hours postdose)
The TETRAS individual item score is the sum of the TETRAS Performance Subscale items 4a, 4b, or 4c scores \[4a: forward outstretched postural tremor (FOPT), 4b: lateral "wing beating" postural tremor (LWBPT), 4c: kinetic tremor\] from both sides of the body. Each TETRAS score ranges from 0 to 4; the total score ranges from 0 to 16; higher scores indicate more severe tremor. A negative change from Baseline indicates improvement.
SecondaryPart A: Change From Baseline in TETRAS Performance Subscale Score (Items 6, 7, and 8) at Day 7Baseline (Day 1) and Day 7 (predose)
The TETRAS Performance Subscale score includes 9 items. Out of these 9 items, Item 6 is Archimedes spirals (AS), Item 7 is Handwriting, and Item 8 is Dot approximation task (DAT). Each item was scored from 0 to 4, for both sides of the body, each item has a total score of 0 to 8, where higher scores indicate more severe tremor. A negative change from Baseline indicates improvement.
SecondaryPart B: Change From Randomization in the Kinesia Upper Limb Total Score at Day 14Randomization (Day 8, predose) and Day 14 (predose)
The accelerometer-based Kinesia upper limb total score is the sum of Kinesia kinetic tremor scores across both sides of the body. The individual items included forward outstretched postural tremor (FOPT), lateral "wing beating" postural tremor (LWBPT), and kinetic tremor (KT) scores from both sides of the body. Each upper limb individual item question score for each side of the body ranges from 0 to 4. The Kinesia upper limb total score ranges from 0 to 24, with higher scores indicating more tremors/greater tremor amplitude. A negative change from Randomization indicates improvement.
SecondaryPart B: Change From Randomization in the Kinesia Upper Limb Individual Item Score at Day 14Randomization (Day 8, predose) and Day 14 (predose)
The accelerometer-based Kinesia upper limb total score is the sum of Kinesia kinetic tremor scores across both sides of the body. The individual items included forward outstretched postural tremor (FOPT), lateral "wing beating" postural tremor (LWBPT), and kinetic tremor (KT) scores from both sides of the body. Each upper limb individual item question score for each side of the body ranges from 0 to 4. The Kinesia upper limb total score ranges from 0 to 24, with higher scores indicating more tremors/greater tremor amplitude. A negative change from Randomization indicates improvement.
