Study Endpoints
Primary Endpoints
Change From Baseline to Week 78 in Neuropsychological Test Battery (NTB) Z-score (Full Analysis Set; FAS)
Baseline and 78 weeks

The NTB assessment is comprised of 9 instruments that measure cognition and executive function. Three of these tests measure immediate memory, next three measure delayed memory, and remaining three assess executive function. The total score is a weighted mean of the nine tests, referred to as the Z-score. Typically, scores range from -3 and 3, with lower scores suggesting greater cognitive impairment.

Additional Analysis of Primary Outcome Measure: Change From Baseline to Week 78 in Neuropsychological Test Battery (NTB) Z-score (Per Protocol Set; PPS)
