Outcome Measures

Primary Outcomes (1)

  • Change From Baseline in the Average of the DSST RBANS Scores at the End of Each Double-blind Treatment Period

    The DSST RBANS (Digit Symbol Substitution Test Repeatable Battery for the Assessment of Neuropsychological Status) is an objective neuropsychological test that assesses executive function, processing speed and attention. DSST RBANS scores range from a minimum of 0 (worse outcome) to a maximum of 100 (better outcome). The change from baseline was calculated as post-baseline - baseline. A positive change indicates improvement.

    Baseline to the end of the second double-blind treatment period (up to 5 weeks)
