Maximum Percent Change From Baseline in Movement Disorder Society-Sponsor Revision of the Unified Parkinson's Disease Rating Scale (MDS-UPDRS) Part III at Day 7. |
The total MDS-UPDRS score is the most common method of evaluating the severity of Parkinson's disease across behaviors, activities of daily living, motor abilities, and other complications of Parkinson's disease. The MDS-UPDRS focuses primarily on measuring impairments associated with Parkinson's disease, with subsections organized according to motor and non-motor aspects of the disease. Part III assesses the motor signs of Parkinson's disease. Higher total scores indicate more severe motor signs of Parkinson's disease. Negative changes from baseline indicate improvement. MDS-UPDRS Part III total motor score is comprised of 33 sub-scores based on 18 items, several with right, left or other body distribution scores. Each question is anchored with five responses that are linked to commonly accepted clinical terms: 0 = normal, 1 = slight, 2 = mild, 3 = moderate and 4 = severe. |

Number of Participants in Each Columbia Classification Algorithm of Suicide Assessment (C-CASA) Category by Study Visit on Day -2, Day 8 or Early Withdrawal, and Early Withdrawal/Follow-Up Visit |
The number of participants in each C-CASA category was mapped from Columbia-Suicide Severity Rating Scale (C-SSRS) data. C-SSRS assessed whether participant experienced following: completed suicide (1), suicide attempt (2) (response of "Yes" on "actual attempt"), preparatory acts toward imminent suicidal behavior (3) ("Yes" on "preparatory acts or behavior"), suicidal ideation (4) ("Yes" on "wish to be dead", "non-specific active suicidal thoughts", "active suicidal ideation with methods without intent to act or some intent to act or some intent to act, with specific plan and intent"), any suicidal behavior or ideation, self-injurious behavior (7) ("Yes" on "Has subject engaged in non-suicidal self-injurious behavior"). |

Number of Participants With Supine and Standing Vital Sign Abnormalities of Potential Clinical Concern (Absolute Values) |
Number of participants with supine and standing vital signs data of absolute values meeting criteria of potential clinical concern. Absolute values were analyzed for supine/standing systolic blood pressure (SBP), supine/standing diastolic blood pressure (DBP), and supine/standing pulse rate. Number of participants with vital signs data meeting the following criteria was reported: (1) absolute supine SBP <90 millimeters of mercury (mmHg); (2) absolute standing SBP <90 mmHg; (3)absolute supine DBP<50mmHg; (4)absolute standing DBP<50mmHg (5) absolute supine pulse rate <40 beats per minute (bpm); (6) absolute supine pulse rate >120 bpm;(7) absolute standing pulse rate <40 bpm; (8) absolute standing pulse rate >140 bpm. |
