Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Efficacy of Xanamem on attention, including working memory	Change from Baseline to EOT in an Attention Composite of a Cognitive Test Battery (CTB) (Detection, Identification, and One Back tests)	6 Weeks (Baseline to Week 6 (end of treatment (EOT)))
Primary	Evaluation of the short-term safety and tolerability of Xanamem	Incidence and severity of treatment-emergent adverse events (TEAEs) Incidence of serious adverse events (SAEs) and SUSARs	6 Weeks (Baseline to Week 6 (EOT))
Secondary	Determine the effects of Xanamem on depressive symptoms	Change from Baseline to EOT on the Montgomery-Åsberg Depression Rating Scale (MADRS).; The MADRS is a 10-item diagnostic questionnaire used to assess the severity of depressive episodes and is designed to be sensitive to treatment effects. Each item is scored from 0 to 6, and overall scores range from 0 to 60. Higher scores indicate greater severity.	6 Weeks (Baseline to Week 6 (EOT))
