Outcome Measures
Primary Outcomes (3)
Part A: Change From Baseline in Accelerometer-based Kinesia Kinetic Tremor Combined Score at Day 7
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.
Baseline (Day 1) and Day 7 (8 hours postdose)
Part B: Change From Randomization in Accelerometer-based Kinesia Kinetic Tremor Combined Score at Day 14
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.
Randomization (Day 8, predose) and Day 14 (predose)
Part C: Change From Baseline in the Accelerometer-based Kinesia Upper Limb Tremor Combined Score at 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.
Baseline (Day 1) and Day 15

Study Arms (5)
Part A: SAGE-217 Oral Solution
EXPERIMENTALParticipants received SAGE-217 10 mg oral solution on Day 1, 20 mg on Day 2 and 30 mg on Days 3 to 7 with food in the morning.
Part A: SAGE-217 Capsules
EXPERIMENTALParticipants received SAGE-217 10 mg capsules on Day 1, 20 mg on Day 2 and 30 mg on Days 3 to 7, orally, with food in the morning.
Part B: Placebo
PLACEBO COMPARATORParticipants who received maximum tolerated dose of SAGE-217 in Part A and achieved response on Day 8 were randomized to receive to SAGE-217 matching placebo for 7 days beginning on Day 8 with food in the morning.
Part B: SAGE-217 Capsules
EXPERIMENTALParticipants who received maximum tolerated dose of SAGE-217 in Part A and achieved response on Day 8 were randomized to receive to SAGE-217 for 7 days beginning on Day 8 with food in the morning.
Part C: SAGE-217 Capsules
EXPERIMENTALParticipants received SAGE-217 10 mg capsules on Day 1, 20 mg on Day 2, 30 mg on Day 3, orally, with food in the evening. Beginning on Day 4 through Day 14, participants received a 40-mg total daily dose (administered as 10 mg with food in the morning and 30 mg with food in the evening).
Interventions
Eligibility Criteria
You may qualify if:
- Participant must have a diagnosis of Essential Tremor (ET), defined as bilateral postural tremor and kinetic tremor, involving hands and forearms, that is visible and persistent and the duration is \>5 years prior to screening.
You may not qualify if:
- Participant has presence of abnormal neurological signs other than tremor or Froment's sign.
- Participant has presence of known causes of enhanced physiological tremor.
- Participant has concurrent or recent exposure (14 days prior to admission visit) to tremorogenic drugs.
- Participant has had direct or indirect trauma to the nervous system within 3 months before the onset of tremor.
- Participant has historical or clinical evidence of tremor with psychogenic origin.
- Participant has convincing evidence of sudden tremor onset or evidence of stepwise deterioration of tremor.
