Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 50 years and older
  • All sexes
  • Adult, Older adult

Who may be able to join

  • Patients with diagnostics of Alzheimer's disease (AD) according to DSM-IV.
  • Patients with modified Hachinski Ischemic scale score of ≦6.
  • FAST score of ≧6 at baseline (4 weeks before starting study treatment).
  • MMSE score between 1 and 12 at baseline (4 weeks before starting study treatment).
  • Imaging diagnostics (CT, MRI, etc., within 24 months consistent with the diagnosis of AD without any other comorbid pathologies found.

  • Patients who can comply with the requirements on concomitant drugs/therapies from the baseline phase or before.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing DONEPEZIL HYDROCHLORIDE in people with Alzheimer Disease, run by Eisai Limited at 65 sites in Japan.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 12 inclusion and 20 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 29 Jan 2010. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 65 sites in Japan. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Primary Outcomes: Efficacy:. The study lists 6 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00165659.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 29 Jan 2010; AzTrials last refreshed its copy on 28 Oct 2026.
