Outcome Measures
Primary Outcomes (1)
Change From Baseline to Week 24 in MATRICS Consensus Cognitive Battery (MCCB) Neurocognitive Composite Score
The MCCB is a cognitive battery to assess 7 domains recommended by the MATRICS initiative (i.e., working memory, verbal learning, speed of processing, attention/vigilance, visual learning, social cognition, reasoning and problem solving). The MCCB neurocognitive composite T-score is a standardized mean of the six domain scores (excluding social cognition). Raw scores are converted to age and sex adjusted t-scores which are standardized to normative data, and have a mean of 50 and standard deviation of 10 in the general healthy population. A higher composite T-score represents lower impairment.
Baseline up to Week 24
