Study Endpoints
Primary Endpoints
Change From Baseline in Modified Motor Score (mMS) (Sum of Score of Items 4-10 and 13-15 of the Unified Huntington's Disease Rating Scale [UHDRS] Motor Assessments) at Week 26
Baseline, Week 26

The mMS is a subscale of the UHDRS total motor score and comprises 13 responses from the 10 items, 4-10 and 13-15, from the UHDRS motor assessment. The items for mMS include dysarthria, tongue protrusion, finger taps (right and left), pronate/supinate hands (right and left), luria - first-hand-palm sequencing, arms rigidity (right and left), body bradykinesia, gait, tandem walking, and retropulsion pull test. Each of these items are rated on a scale of 0 (normal) to 4 (marked impairment). Total score ranges from 0 to 52, with higher scores indicating more severe motor impairment.
