About this study

Official title: Effects of 15-day Donepezil and Memantine on Cognitive Functions After a 24 Hours Sleep Deprivation Challenge in Healthy Volunteers: a Double-blind, Placebo-controlled, Randomised, Cross-over Study, With Modafinil as Positive Control

The aim of this study is to assess the utility of sleep deprivation as a potential model for prediction of clinical efficacy using a combination of cognitive physiological endpoints.

Read the detailed description

BACKGROUND:

With the inherent difficulty of detecting significant improvements in cognitive performance in normal healthy subjects, it is presently incredibly hard to predict and select efficacious agents early in the drug development process. As such the potential success of novel therapeutic agents for the symptomatic relief of Alzheimer's disease (AD) is largely unknown until the drugs enter relatively large studies, assessing clinical outcome over at least a six month period. To try to overcome this issue, clinical scientists have focused their attention to the development of cognitive endpoints/biomarkers that can be detected in a number of experimental paradigms where cognitive impairments akin to those observed in AD, have been artificially induced.Based on the scientific literature, the use of total Sleep Deprivation in healthy volunteers seems to be a good paradigm to assess potential anti-AD agents.

It is the first multicenter study that combines 3 complementary approaches via a standardization of the sleep deprivation model: cognitive evaluations, imaging and neurophysiology.

STUDY OBJECTIVE(S)

Primary:

The study aim is to assess the utility of sleep deprivation as a potential model for prediction of clinical efficacy using a combination of cognitive physiological endpoints.

The main goals are to test the effects of donepezil and memantine treatment on cognitive functions in young healthy deprived subjects and to assess the potential restoring effect of the two drugs on cognitive functions induce by sleep deprivation.

Secondary:

  • To assess that Sleep Deprivation model results in cognitive impairments
  • To determine the sensitivity of the model by testing the restoring effects of one single dose of modafinil
  • To investigate the reversal effect of modafinil on EEG under sleep deprivation.
  • To investigate the reversal effect of modafinil on fMRI acquisitions under sleep deprivation (subjects that will be included in Toulouse will not have fMRI)
  • To investigate the influence of donepezil and memantine on EEG under sleep deprivation.
  • To investigate the influence of donepezil and memantine on fMRI acquisitions under sleep deprivation (subjects that will be included in Toulouse will not have fMRI).

STUDY DESIGN The study is a phase I, multicentric (Lille, Marseille, Toulouse), randomised, placebo-controlled, cross-over design.

STUDY POPULATION Healthy young male subjects from 25 to 40 years-old (36 subjects randomized)

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in N-back

    The N-back test is both sensitive to SD in healthy volunteers and this test belongs to ADNI cognitive battery which is validated in Alzheimer's disease patients,considered as primary endpoint.

    Measured: Day 1 and Day 2 for each of the 5 Period

Secondary outcomes (3)
  1. Other cognitive assessments

    CANTAB Battery, Memory Rey Auditory Verbal Learning Test (AVLT), Digit Span Test, Verbal Fluency task

    Measured: Day 1 and Day 2 for each of the 5 Period

  2. fMRI

    Resting fMRI, fMRI Memory task

    Measured: Day 1 and Day 2 for each of the 5 Period

  3. Rest-EEG and P300 after auditory-ball paradigm Rest-EEG and P300 after auditory-ball paradigm Rest-EEG and P300 after auditory-ball paradigm

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Modafinil, Donepezil and Memantine in people with Healthy, run by Qualissima at 2 sites in France.

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 19 inclusion and 15 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 4 Feb 2015. 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 France. 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 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?

Change in N-back (time frame: Day 1 and Day 2 for each of the 5 Period). 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 4 Feb 2015.
