What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change From Baseline in TMC Score in Participants Receiving ≥24 mg/Day
Time Frame: 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).
Baseline, Week 16

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Number of Participants With Any Adverse Events (AEs) By Severity Grade
Time Frame: 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
Change From Baseline in TMC Score in All Participants Regardless of Study Drug Dose
Time Frame: 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).
