Brief summary
Xanamem is being developed as a potential treatment for symptomatic, early stages of Alzheimer's Disease (AD) and Major Depressive Disorder (MDD). This XanaCIDD Phase II study in MDD is to investigate the safety and efficacy of Xanamem™ in treating patients with cognitive and depressive symptoms. Trial participants will be randomized to either receive 10mg of Xanamem™ once daily or a Placebo at a 1:1 ratio in a double-blinded fashion.
Interventions
Xanamem™ is formulated in green and cream-colored size 3, Coni-Snap-shaped gelatin capsules as an excipient blend at a dose of 10mg. It contains the active pharmaceutical ingredient of UE2343.
Matching placebo which is identical in appearance to the test product (10 mg Xanamem™ QD) except that it contains no active ingredient.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Efficacy of Xanamem on attention, including working memory | 6 Weeks (Baseline to Week 6 (end of treatment (EOT))) | Change from Baseline to EOT in an Attention Composite of a Cognitive Test Battery (CTB) (Detection, Identification, and One Back tests) |
| Evaluation of the short-term safety and tolerability of Xanamem | 6 Weeks (Baseline to Week 6 (EOT)) | Incidence and severity of treatment-emergent adverse events (TEAEs) Incidence of serious adverse events (SAEs) and SUSARs |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Determine the effects of Xanamem on depressive symptoms | 6 Weeks (Baseline to Week 6 (EOT)) | 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. |
