结局指标
主要结局
Number of Participants With Neurocognitive Domains Preserved at Month 9
时间窗: Month 9
Preservation of NF was defined as a decrease of \<=1 SD, any increase, or no change (0 SD) in z-score for each domain (memory domain, executive function domain, and fine motor coordination domain).
Rate of Deterioration in Neurocognitive Functioning (NF) at Month 12
时间窗: Month 12
NF was assessed as the performance of 3 neurocognitive domains:memory(MD),executive function(EFD), fine motor coordination(FMCD). For each domain, z-scores were derived from participant's scores in individual neurocognitive tests using an age-adjusted and education-adjusted normative distribution of scores from an unimpaired population.Individual z-scores from related tests were averaged to determine overall z-score.If a z-score average decreased from baseline by greater than or equal to(\>=)3 standard deviations(SD)in tests' normative age-adjusted distribution on 2 consecutive visits or decreased by \>=3 SD on last follow-up visit, participant were considered to have significant deterioration in their NF at time of the first decrease in z-score.Deterioration in NF:demonstrated deterioration for at least two of the three neurocognitive domains based on these changes from screening.Rate of deterioration in NF was measured as estimated percentage of participants using Kaplan-Meier method.
Number of Participants With Neurocognitive Domains Preserved at Month 2
时间窗: Month 2
Preservation of NF was defined as a decrease of \<=1 SD, any increase, or no change (0 SD) in z-score for each domain (memory domain, executive function domain, and fine motor coordination domain).
Number of Participants With Neurocognitive Domains Preserved at Month 4
时间窗: Month 4
Preservation of NF was defined as a decrease of \<=1 SD, any increase, or no change (0 SD) in z-score for each domain (memory domain, executive function domain, and fine motor coordination domain).
Number of Participants With Neurocognitive Domains Preserved at Month 6
时间窗: Month 6
Preservation of NF was defined as a decrease of \<=1 SD, any increase, or no change (0 SD) in z-score for each domain (memory domain, executive function domain, and fine motor coordination domain).
Number of Participants With Neurocognitive Domains Preserved at Month 12
时间窗: Month 12
Preservation of NF was defined as a decrease of less than or equal to (\<=) 1 SD, any increase, or no change (0 SD) in z-score for each domain (memory domain, executive function domain, and fine motor coordination domain).
