Participant Flow

193 participants were enrolled into the study and randomized to one of the 4 treatment arms. However, 1 participant withdrew from the study prior to beginning treatment with study IP and hence is not included in the overall number of 192 participants who received study IP and for which post-baseline assessments were performed.

The CANTAB global composite score is based on the Z scores for CANTAB outcome measures (PAL first attempt memory score (PALFAMS), PAL total errors adjusted (PALTEA), SWM between errors (SWMBE), SWM strategy (SWMS), RVP A' prime (RVPA), RVP median latency (RVPMDL). Specifically, the global composite score of cognitive function is as follows: CANTAB global composite score of cognitive function = (ZPALFAMS + ZPALTEA + ZSWMBE + ZSWMS + ZRVPA + ZRVPMDL) /8 (higher is better) A Z-score of 0 represents the population mean. A Z-score above 0 indicates cognition higher than the population mean and Z-score below 0 indicates cognition lower than the population mean
