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 to 85 years
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • Meets the current cognitive classification of MCI or mild dementia due to AD pathology (all subjects having a "positive" biomarker for amyloid β) as defined by the National Institute on Aging - Alzheimer's Association (NIA-AA) research criteria
  • Aged 50 to 85 years, inclusive at time of consent

Who cannot join

  • Currently has any neurological condition other than AD (Alzheimer's disease)-related that could be contributing to the subject's cognitive impairment
  • Significant pathological findings on brain MRI at Screening, including but not limited to multiple microhemorrhages
  • Any psychiatric diagnosis or symptoms, e.g., hallucinations, major depression,anxiety or delusions that in the Investigator's opinion could interfere with assessment of cognition or confound the diagnosis of MCI or mild dementia due to AD in the subject.
  • A lifetime history of cerebrovascular events or non-vasovagal related loss of consciousness within the last 10 years
  • Any other abnormality of the ECG at Screening and/or Baseline (including QRS > 110 ms, abnormal electrical axis, PR interval > 220 ms and conduction abnormalities) considered clinically significant by the investigator
  • History of cardiac arrhythmias, ischemic heart disease or cerebrovascular disease
  • Lower spinal malformation on physical or lumbar spine radiography, local spinal infection, or other abnormality, including but not limited to obesity, that would prevent LP or insertion of an indwelling catheter for CSF sampling
  • Any history of seizure disorder, symptomatic seizures (not including a history of simple febrile seizures in childhood) or any past or present medical condition which, in the opinion of the investigator has the potential to reduce seizure threshold (e.g., history of head trauma or concussion, previous alcohol abuse, substance abuse).

About this study

Official title: A Randomized, Double-blind, Placebo-controlled Study to Evaluate the Safety, Tolerability, Pharmacokinetics, and Pharmacodynamics of Single Oral Doses of E2609 in Subjects With Mild Cognitive Impairment or Mild Dementia Due to Alzheimer's Disease

Subjects will be adults aged 50 to 85 years who have subjective memory complaints and mild cognitive impairment or mild dementia due to Alzheimer's disease (AD). Subjects taking thyroxine or thyroid supplements and subjects receiving an acetylcholinesterase inhibitor (AChEI) and/or memantine for AD must be on a stable dose for at least 12 weeks prior to Screening and remain on their stable dose throughout the trial. Subjects will receive placebo or a single oral dose of E2609. Safety assessments will be conducted. Additionally, the pharmacokinetics of E2609 and drug effects will be evaluated using cerebrospinal fluid biomarkers and cognitive and psychological measures.

Being tested
E2609, Placebo for E2609

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • E2609Drug

    E2609 capsules: 5 mg, 25 mg, 50 mg, and 200 mg

    E2609 doses: 5 mg, 10 mg, 25 mg, 50 mg, 100 mg, 200 mg, and 400 mg

    According to the randomized study design, participants who are assigned to receive E2609 will each receive a single assigned dose consisting of two capsules of E2609 or in some cases one capsule of E2609 and one of placebo

  • Placebo for E2609Drug

    Placebo capsules

    According to the randomized study design, participants who are assigned to receive placebo will each receive a single dose consisting of two capsules of placebo

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing E2609 in people with Alzheimer's Disease, run by Eisai Inc. at 2 sites in United States.

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 2 inclusion and 8 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 30 Dec 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United States. 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. Some participants in this study may receive a placebo. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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?

Percent change from baseline in cerebrospinal fluid amyloid-beta levels (time frame: baseline to 36 hours post-dose). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 30 Dec 2016.
