ListOutcomeTime frameDescription
PrimaryChange From Baseline in Cambridge Neuropsychological Test Automated Battery (CANTAB) Cognitive Domain Spatial Working Memory (SWM) Strategy Z-Score at Week 96Week 96
CANTAB SWM task assessed cognitive domain of executive function. Colored boxes were shown on a screen. A token was hidden in one of the boxes (never same box twice). Instructions were to touch boxes to search for token until number of tokens found equaled number of boxes. SWM strategy index represents number of times a search began with a different box. Z-score represents standardized measure of how far an individual deviated from study cohort average at baseline. A higher Z-score reflects better performance.
SecondaryChange From Baseline in CANTAB Cognitive Domain SWM Strategy Raw Score at Week 96Week 96
CANTAB SWM task assessed cognitive domain of executive function. Colored boxes were shown on a screen. A token was hidden in one of the boxes (never same box twice). Instructions were to touch boxes to search for token until number of tokens found equaled number of boxes. SWM strategy index represents number of times a search began with a different box. Lower change from baseline raw scores reflect better SWM performance (i.e. less impairment).

Primary safety population included participants from the safety population who had an assessment of the SWM strategy score at baseline, and at least 1 score measured during the treatment-emergent adverse event (TEAE) period. The TEAE period is defined as the first double-blind treatment dose to last dose of double-blind treatment + 70 days (10 weeks). Participants were analyzed according to the treatment actually received.

ITT Population was used. The two-step multiple imputation procedure is used to address missing values in the randomized population. In the first step, the monotone missing pattern is induced in the multiply-imputed data. In the second step, the missing data at subsequent visits are imputed using the regression method for continuous variables.
