Tiltaksbeskrivelse
Tidsramme
Change From Baseline in TMC Score in Participants Receiving ≥24 mg/Day
Tidsramme: Baseline, Week 16
The TMC score was determined from Item 12 of the motor assessment (Part 1) of the UHDRS and quantifies chorea (range, 0-28, lower score indicated less chorea). It was the sum of maximal chorea scores for 7 body regions (face, buccal-oral-lingual, trunk, and 4 extremities), each of which was scored on a scale from 0 to 4 (0, absent; 1, slight or intermittent; 2, mild and common or moderate and intermittent; 3, moderate and common; and 4, marked and prolonged).

Tidsramme
Number of Participants With Any Adverse Events (AEs) By Severity Grade
Tidsramme: Baseline up to Week 16
AE: any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. Severity of AEs recorded as one of following Common Terminology Criteria for Adverse Events (CTCAE) criteria: -Grade 1: Mild; asymptomatic or mild symptoms; clinical/diagnostic observations only; intervention not indicated. -Grade 2: Moderate; local or noninvasive intervention indicated; limiting age-appropriate instrumental Activities of Daily Living (ADL) (for example, preparing meals, shopping for groceries or clothes, using telephone). -Grade 3: Severe or medically significant but not immediately life-threatening; hospitalization; disabling; limiting self-care ADL (bathing, dressing, feeding self, using toilet, taking medications, and not bedridden). -Grade 4: Life-threatening; urgent intervention indicated. -Grade 5: Death related to AE. A summary of other non-serious AEs and all serious AEs, regardless of causality is located in Reported AE section.
Baseline up to Week 16
Number of Participants With Serious Adverse Events (SAEs)
Tidsramme: Baseline up to Week 16
An AE was defined as any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. The SAEs were defined as death, a life-threatening AE, inpatient hospitalization or prolongation of existing hospitalization, persistent or significant disability or incapacity, a congenital anomaly or birth defect, or an important medical event that jeopardized participant and required medical intervention to prevent 1 of the outcomes listed in this definition. A summary of other non-serious AEs and all serious AEs, regardless of causality is located in the Reported AE section.
Baseline up to Week 16
Number of Participants With Treatment-related AEs
Tidsramme: Baseline up to Week 16
An AE was defined as any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. Number of participants with treatment-related AEs is reported in this outcome measure. A summary of other non-serious AEs and all serious AEs, regardless of causality is located in the Reported AE section.
Baseline up to Week 16
Number of Participants With AEs Leading to Dose Reduction, Interruption, Treatment Discontinuation, and Study Withdrawal
Tidsramme: Baseline up to Week 16
An AE was defined as any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. Number of participants with AEs leading to dose reduction, interruption, treatment discontinuation, and study withdrawal is reported in this outcome measure. A summary of other non-serious AEs and all serious AEs, regardless of causality is located in the Reported AE section.
Baseline up to Week 16
Number of Participants With AEs in Titration Phase
Tidsramme: Baseline up to Week 16
An AE was defined as any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. AEs lasted from titration phase to maintenance phase were considered an AE that occurred in the titration phase. A summary of other non-serious AEs and all serious AEs, regardless of causality is located in the Reported AE section.
Baseline up to Week 16
Number of Participants With AEs in Maintenance Phase
Tidsramme: Baseline up to Week 16
An AE was defined as any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. A summary of other non-serious AEs and all serious AEs, regardless of causality is located in the Reported AE section.
Baseline up to Week 16
Number of Participants With AEs of Special Interest
Tidsramme: Baseline up to Week 16
An AE was defined as any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. AEs of special interest included suicidality, depression, somnolence, QTc prolongation, akathisia, and parkinsonism. A summary of other non-serious AEs and all serious AEs, regardless of causality is located in the Reported AE section.
Baseline up to Week 16
Change From Baseline in TMC Score in All Participants Regardless of Study Drug Dose
Tidsramme: Baseline, Week 16
The TMC score was determined from Item 12 of the motor assessment (Part 1) of the UHDRS and quantifies chorea (range, 0-28, lower score indicated less chorea). It was the sum of maximal chorea scores for 7 body regions (face, buccal-oral-lingual, trunk, and 4 extremities), each of which was scored on a scale from 0 to 4 (0, absent; 1, slight or intermittent; 2, mild and common or moderate and intermittent; 3, moderate and common; and 4, marked and prolonged).
