Časové okno: Baseline, Week 4
GAF is a 100-point, clinician rated single item scale that rates the severity of illness-related impairment in psychological, social and occupational functioning of participants on a hypothetical continuum of mental illness to mental health. The scale values range from 1 to 100 with lower score indicating greater severity of illness and is divided into 10 equal intervals (descriptors): from 1-10 (persistent danger of hurting self - serious suicidal acting with clear expectations of death) to 91-100 (superior functioning - no symptoms). Each descriptor has a nine-point range to allow for some variability of severity within the descriptor.
Baseline, Week 4
Treatment Satisfaction Questionnaire for Medication (TSQM) Score
Časové okno: Week 4
TSQM assesses the participant's level of satisfaction with study medication. It consists of a 14-item questionnaire which comprises of 3 specific scales (effectiveness, side effects, convenience) and 1 global satisfaction scale. Effectiveness, convenience and global satisfaction scale are rated on a 7-point scale (0= Extremely Dissatisfied, 1= Very Dissatisfied, 2= Dissatisfied, 3= Somewhat Satisfied, 4= Satisfied, 5= Very Satisfied, 6= Extremely Satisfied) and side effects are rated on a 5-point scale (0= Extremely Dissatisfied, 1=Very Dissatisfied, 2= Somewhat Dissatisfied, 3= Slightly Dissatisfied, 4= Not at all Dissatisfied). Scale scores are transformed into scores ranging from 0 to 100, with a higher score indicating more satisfaction.

ESRS-A is a clinician rated scale consisting of 24 items to assess severity of extra-pyramidal symptoms for following parameters: parkinsonism (10 items), dystonia (6 items), dyskinesia (6 items) and akathisia (2 items). Each item is scored on a 6-point Likert scale (0=absent, 1=minimal, 2=mild, 3=moderate, 4=severe, 5=extreme).

Change From Baseline in Movement Disorder Burden Score for Dystonia (MDBS-D) at Week 4
Časové okno: Baseline, Week 4
MDBS-D score reflects the numbers and durations of movement disorder adverse events for dystonia, the severity of the events, required treatment, and the total number of days the participant received study treatment. MDBS-D score = (S * D * C)/TTD; where S= Movement Disorder Severity Score for Dystonia (possible values: 1 [mild]; 2 [moderate]; 3 [severe]), D=adverse event duration (in days), C=concomitant medication factor (C=1.5 if an anti-cholinergic or beta blocker is used for the treatment of a movement disorder; C=1 if no concomitant medication is used), TTD=total treatment days for the participant. Value for MDBS score may range from zero to infinity. A higher MDBS-D score indicates a greater movement disorder adverse event liability compared to baseline.

Data relevant to the assessment of suicidality is mapped to the Columbia Classification Algorithm of Suicide Assessment (C-CASA) event codes. C-SSRS assesses whether participant experiences following: suicide attempt (Event code 2) (Response of "Yes" on "actual attempt"), preparatory acts toward imminent suicidal behavior (Event code 3) ("Yes" on "aborted attempt", "interrupted attempt", "preparatory acts or behavior"), suicidal ideation (Event code 4) ("Yes" on "wish to be dead", "non-specific active suicidal thoughts", "active suicidal ideation with methods without intent to act/some intent to act without specific plan or with specific plan and intent), self-injurious behavior, no suicidal intent (Event code 7) ("Yes" on "Has participant engaged in non-suicidal self-injurious behavior"). Number of participants with "Yes" response for above mentioned categories are assessed. Baseline is defined as the Week 0 measurement.
