Primární výstupní opatření

Měření výsledku
Popis opatření
Časové okno
Change From Baseline in TMC Score in Participants Receiving ≥24 mg/Day
Časové okno: 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).
