Primary Outcome Measures:
  • Number of Participants Reporting Serious Adverse Events or Other Adverse Events Leading Either to Discontinuation or to Death [ Time Frame: baseline through 12 weeks ] [ Designated as safety issue: Yes ]
    The results reported are the number of participants who discontinued the study as a result of an adverse event (serious or other) or death.


Secondary Outcome Measures:
  • Change From Baseline to 12 Weeks on the Unified Parkinson's Disease Rating Scale (UPDRS) Total Score [ Time Frame: baseline, 12 weeks ] [ Designated as safety issue: Yes ]
    Rating tool to follow the longitudinal course of Parkinson's Disease. It is composed of Section I: Mentation, Behavior, and Mood; Section II: Activities of Daily Living; Section III: Motor Examination; Section IV: Complications of therapy. These are evaluated by interview. Some sections require that multiple grades be assigned to each extremity. Only Sections II and III were rated in this study. A total of 160 points are possible (52 in Section II and 108 in Section III), where 0 represents no disability and 160 indicates maximal grade of disability.

  • Change From Baseline to 12 Weeks on the UKU (Udvalg for Kliniske Undersogelser: Committee for Clinical Investigations) Side Effect Rating Scale [ Time Frame: baseline, 12 weeks ] [ Designated as safety issue: Yes ]
    Clinician-rated scale, providing side effect ratings of psychopharmacological medications. 48 items, each item is rated on a 4-point scale (0=not present; 1=mild; 2=moderate; 3=severe). The test is divided in 6 subscales, total scores for each subscale are calculated based on a weighted secondary scoring system. Subscales: psychic (score range:0-30), neurological (score range:0-24), autonomic (score range:0-33), other (score range:0-75), global assesment by subject (score range:0-3), and global assessment by doctor (score range:0-3). Higher ratings indicate greater impairment.

  • Change From Baseline on the Pittsburgh Sleep Quality Index (PSQI) [ Time Frame: baseline, 4 weeks, 8 weeks, 12 weeks ] [ Designated as safety issue: No ]
    Self-rated questionnaire which assesses sleep quality and disturbances over a 1-month time interval. 19 individual items generate seven "component" scores: subjective sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disturbances, use of sleeping medication, and daytime dysfunction. The subject self-rates each of these seven areas of sleep. Scoring of answers is based on a 0 to 3 scale, whereby 3 reflects the negative extreme on the Likert Scale. The total score is the sum of the 7 component scores (total score range: 0-21).

  • Change From Baseline to 12 Weeks on the 17-item Hamilton Depression Rating Scale (HAMD-17) Total Score [ Time Frame: baseline, 12 weeks ] [ Designated as safety issue: No ]
    The 17-item HAMD measures depression severity. Each item was evaluated and scored using either a 5-point scale (e.g. absent, mild, moderate, severe, very severe) or a 3-point scale (e.g. absent, mild, marked). The total score of HAMD-17 may range from 0 (normal) to 52 (severe).

  • Change From Baseline to 12 Weeks on the Clinical Global Impression-Severity Scale [ Time Frame: baseline, 12 weeks ] [ Designated as safety issue: No ]
    Measures severity of illness at the time of assessment compared with start of treatment. Scores range from 1 (normal, not at all ill) to 7 (among the most extremely ill patients).

  • Patient's Global Impression-Improvement at Week 12 [ Time Frame: 12 weeks ] [ Designated as safety issue: Yes ]
    A scale that measures the patient's perception of improvement at the time of assessment compared with the start of treatment. Scoring: 1=very much better; 2=much better; 3=low better; 4=no change; 5=low worse; 6=much worse; 7=very much worse.

  • Change From Baseline to 12 Weeks in Beck Depression Inventory (BDI) Total Score [ Time Frame: baseline, 12 weeks ] [ Designated as safety issue: No ]
    A 21-item, patient-completed questionnaire to assess characteristics of depression. Each of the 21 items corresponding to a symptom of depression is summed to give a single score. There is a four-point scale for each item ranging from 0 to 3. Total score of 0-13 is considered minimal range, 14-19 is mild, 20-28 is moderate, and 29-63 is severe.

  • Change From Baseline to 12 Weeks in Visual Analog Scale (VAS) [ Time Frame: baseline, 12 weeks ] [ Designated as safety issue: No ]
    VAS for pain consists of 6 questions that assess overall pain, headache, back pain, shoulder pain, pain interference with daily activities, and pain while awake. Participant rates pain on a 100 millimeter (mm) line between two anchors (0= no pain and 100=very severe pain). Here, the line was only 93 mm long due to an error on the clinical research form and scores were adjusted to 0 to 93.

  • Change From Baseline to 12 Weeks in Parkinson Disease Questionnaire - 39 Item Version (PDQ-39) Total Score [ Time Frame: baseline, 12 weeks ] [ Designated as safety issue: No ]
    The PDQ-39 has 39 items. Higher scores reflect lower quality of life. The PDQ-39 has eight subscales: mobility (10 items), activities of daily living (six items), emotional wellbeing (six items), stigma (four items), social support (three items), cognition (four items), communication (three items), and bodily discomfort (three items). Items in each subscale, as well in the total scale, can be summarized into an index and transformed linearly to a 0-100 scale.

  • Average Change From Baseline to 12 Weeks in Blood Pressure [ Time Frame: baseline through 12 weeks ] [ Designated as safety issue: Yes ]
    For each participant, changes across individual visits were averaged to obtain 1 measurement per participant.

  • Average Change From Baseline to 12 Weeks in Heart Rate [ Time Frame: baseline through 12 weeks ] [ Designated as safety issue: Yes ]
    For each participant, changes across individual visits were averaged to obtain 1 measurement per participant.

  • Number of Participants With Abnormal Electrocardiograms (ECG) During the 12 Week Study [ Time Frame: baseline through 12 weeks ] [ Designated as safety issue: Yes ]
    Included were participants with normal ECG at baseline who developed abnormal ECGs during the study.

  • Laboratory Analytes [ Time Frame: baseline through 12 weeks ] [ Designated as safety issue: Yes ]
    Laboratory analytes were collected to assess adverse events which are listed in the reported adverse events section.

  • Number of Participants Who Responded to Treatment by 12 Weeks [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
    Response was defined as a >= 50% reduction in 17-item Hamilton Depression rating scale (HAMD) scores. The 17-item HAMD measures depression severity. Each item was evaluated and scored using either a 5-point scale (e.g. absent, mild, moderate, severe, very severe) or a 3-point scale (e.g. absent, mild, marked). The total score of HAMD-17 may range from 0 (normal) to 52 (severe).

  • Number of Participants Who Reached Remission by 12 Weeks [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
    Remission was defined as reaching a 17-item Hamilton Depression Rating Scale (HAMD) total score <=7. The 17-item HAMD measures depression severity. Each item was evaluated and scored using either a 5-point scale (e.g. absent, mild, moderate, severe, very severe) or a 3-point scale (e.g. absent, mild, marked). The total score of HAMD-17 may range from 0 (normal) to 52 (severe).
