What this trial studies

This clinical trial investigates the safety, tolerability, and efficacy of Xanamem, a potential treatment for mild to moderate dementia due to Alzheimer's Disease. Participants aged 50 and older will be randomly assigned to receive either 10 mg of Xanamem or a placebo daily for 36 weeks in a double-blind manner. The study aims to determine if Xanamem can improve symptoms associated with early stages of Alzheimer's Disease. Eligible participants must meet specific cognitive and diagnostic criteria to ensure they have dementia likely due to Alzheimer's.

Who should consider this trial

Good fit: Ideal candidates are individuals aged 50 and older with mild to moderate dementia likely due to Alzheimer's Disease.

Not a fit: Patients with severe dementia or alternative diagnoses for their cognitive impairment may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide symptomatic relief and improve quality of life for patients with early-stage Alzheimer's Disease.

How similar studies have performed: Other studies have explored treatments for Alzheimer's Disease, but the specific approach with Xanamem is relatively novel.

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.

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.

Exclusion Criteria:

* Use of anti-amyloid or anti-tau antibody within 6 months.

* 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.
