About this study

The purpose of this study is to change the concentration of amyloid-beta in human cerebrospinal fluid (CSF) through modulation of the sleep-wake cycle.

Read the detailed description

The purpose of this research study is to investigate whether or not increasing or decreasing duration of sleep over one night will change the concentration of amyloid-beta in cerebral spinal fluid (CSF).

Conditions
Amyloid-beta
Being tested
Sodium Oxybate, Sleep deprivation
Medical subject headings
Plaque, Amyloid

What participants receive

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

  • Sodium OxybateDrug

    Also called Xyrem

    Sodium oxybate h.s.

  • Sleep deprivationBehavioural

    36hr sleep deprivation

Study groups in NCT02063217
Study groupRoleWhat they receive
Sleep InductionExperimental7.5 grams of sodium oxybate
Receives: Drug: Sodium Oxybate
Sleep DeprivationExperimentalSleep deprivation for up to 36 hours with no naps or other sleep periods
Receives: Behavioral: Sleep deprivation
ControlNo interventionParticipant will sleep as normal under the same controlled conditions in a clinical research unit

What is being measured

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

  1. Percent Increase From Mean Baseline (07:00 to 19:00) of Cerebrospinal Fluid (CSF) Amyloid Beta During Sleep Induction and Sleep Deprivation Between 01:00 and 11:00 From Baseline

    Overnight (01:00 to 11:00) differences in CSF amyloid beta from baseline (07:00 to 19:00) between 1) sleep-deprived and control participants and 2) sleep-induced and control participants.

    Measured: Baseline = 07:00 to 19:00; Intervention period = 01:00 to 11:00

Questions about this trial

What is this clinical trial studying?

A study testing Sodium Oxybate and Sleep deprivation in people with Amyloid-beta, run by Washington University School of Medicine at 1 site 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 4 inclusion and 30 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 26 Apr 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site 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. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Yes. Results are posted in the registry (first posted 26 Apr 2018). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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 Increase From Mean Baseline (07:00 to 19:00) of Cerebrospinal Fluid (CSF) Amyloid Beta During Sleep Induction and Sleep Deprivation Between 01:00 and 11:00 From Baseline (time frame: Baseline = 07:00 to 19:00; Intervention period = 01:00 to 11:00). 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 26 Apr 2018.
