Changes in chorea and motor scores

	Change in UHDRS TMC score	Change in UHDRS TMS
Change from baseline to week 8
Rollover cohort	− 4.4 (3.1)	− 7.1 (7.3)
Switch cohort	− 2.1 (3.3)	− 2.4 (8.7)
Change from week 8 to week 145a
All subjects	− 0.5 (5.2)	8.2 (11.9)

Values shown are mean (SD)

SD standard deviation, TMC total maximal chorea, TMS total motor score, UHDRS Unified Huntington’s Disease Rating Scale

^aThe Rollover and Switch cohorts were analyzed separately from baseline through week 8. The two cohorts were combined for the analysis of changes from week 8 to week 145 (or the last visit on the study drug, if that occurred earlier)
