† | Post hoc analysis included patients who had a baseline and an end of treatment TMC score (n=112). |
Baseline is the average of screening and Day –1 assessments; end of treatment is the average of the Week 10 and Week 12 assessments. |

Greater than 80% of subjects were at the 80 mg dose at the end of the 12-week treatment period. |

TMC, Total Maximal Chorea. |
Physicians and patients reported significant improvements in overall chorea symptoms1,2
More physicians and patients rated overall symptoms of chorea as “very much improved” or “much improved” with INGREZZA® (valbenazine) capsules vs placebo at Week 121,2
