Effect of 10 mg Xanamem on Dementia Due to Alzheimer's Disease

Running, not enrolling · Phase 2/Phase 3 · Has a placebo group

Conditions studied: Dementia Moderate, Dementia, Mild, Alzheimer Disease

In brief

Xanamem® is being developed as a potential treatment for symptomatic, early stages of Alzheimer's Disease (AD) and Major Depressive Disorder (MDD). This XanaMIA Phase 2b/3 study is to investigate the safety, tolerability, and efficacy of Xanamem in in mild or moderate dementia due to AD. Trial participants will be randomized to either receive 10mg of Xanamem once daily or a placebo for 36 weeks at a 1:1 ratio in a double-blinded fashion. Participants who have completed the main trial will be eligible to participate in an open-label phase, which involves treatment with 10mg Xanamem once daily for a treatment period of up to a maximum of 108 weeks. The OLE is intended to finish when all participants have completed at least 60 weeks of treatment and a follow-up visit 4 weeks later.
