Summary

This study tests whether a daily 10 mg pill called Xanamem can safely slow memory and function loss in people with mild or moderate Alzheimer's dementia. About 247 participants will receive either Xanamem or a placebo for 36 weeks, with an option to continue the drug for up to 108 weeks. The main goal is to see if the drug improves scores on a standard dementia rating scale.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Xanamem (a drug taken as a daily pill)
What this could lead to
If successful, Xanamem could become a new daily treatment to slow cognitive and functional decline in early Alzheimer's disease.
What could go wrong
This is a mid-stage trial with only 247 participants, so results may not confirm benefit. The drug is still experimental, and side effects are possible.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Male or female aged 50 years or older, inclusive at the time of Screening. * Clinical syndrome of mild or moderate dementia, likely to be due to AD in the opinion of the Investigator, at Screening, including meeting the following criteria: 1. Clinical Dementia Rating (CDR) global score of 0.5 to 1.0 2. Mini-mental state examination (MMSE) score of 18 to 26 3. Magnetic resonance imaging (MRI) or computerized tomography (CT) scan within 1 year prior to randomization that excludes alternative diagnoses for dementia such as large stroke, likely vascular dementia, brain tumor, subdural hematoma, or other non-AD dementia type findings 4. Positive plasma AD biomarker signature at Pre-screening, comprising fasting levels of a tau species protein. * If receiving symptomatic AD medications, the dosing regimen must have been stable for 3 months prior to Screening. * Has a consenting trial partner who, in the Investigator's judgment, has frequent and sufficient contact with the participant to be able to provide accurate information as to the participant's cognitive and functional abilities. The trial partner must be available to provide information to the Investigator and trial site staff about the participant and agrees to attend all trial site visits in person for scale completion. A trial partner should be available for the duration of the trial. The measure of adequate availability will be at the Investigator's discretion. * Participants must be able to comfortably abstain from caffeine intake for 4 hours prior to scheduled cognitive assessments. * Smokers are eligible if they are able to comfortably abstain from nicotine / tobacco products for 2 hours prior to scheduled cognitive assessments. * Must provide written informed consent to participate in the trial and be willing and able to participate for the maximum of 9 months of treatment and up to 11.5 months of site visits. Exclusion Criteria: * Use of anti-amyloid or anti-tau antibody within 6 months. * Diagnosis of a non-AD dementia including traumatic brain injury. * Diagnosis of an active major mental illness of concern in the opinion in the Investigator, including major depressive disorder, bipolar illness, or schizophrenia. * Participation in another clinical trial of a drug or device * Has a body mass index or body weight that will interfere with participation in the trial, including inadequate venous access to complete the trial assessments, to be determined at the discretion of the Investigator. * Previous clinically significant systemic illness or infection, including test positive COVID-19, within the past 4 weeks prior to Screening. * Clinical diagnosis of Type I or Type II diabetes requiring insulin. * Exhibit physical, cognitive, or language impairments, in the opinion of the Investigator, of such severity as to adversely affect the validity of the data derived from the neuropsychological tests. * Trial participants with evidence of current infection with HIV, hepatitis B, or hepatitis C. * Participants with a history of clinically significant drug abuse or addiction in the past 2 years * Evidence or history of alcohol abuse
