Trial summary

Post-Traumatic Stress Disorder (PTSD) is a public health problem due to both its chronic nature and the low response rate to conventional therapies. Sleep disorders are the first cause of complaint in patients with PTSD due to night awakenings, difficulty to fall asleep and nightmares. Read more about this study

About this study

Post-Traumatic Stress Disorder (PTSD) is a public health problem due to both its chronic nature and the low response rate to conventional therapies.

Sleep disorders are the first cause of complaint in patients with PTSD due to night awakenings, difficulty to fall asleep and nightmares.

Read more

According to a part of the scientific community, replicative traumatic nightmares represent PTSD's basis mechanism. Traumatic nightmares generate disabling symptoms such as anxiety reactions, while maintaining the symptoms by depriving the individual of good quality sleep. Traumatic nightmares may thus be a sign of PTSD seriousness and chronicity, although their physiological basis remain poorly known.

In the military population, which is highly exposed to psychological traumatism, PTSD prevalence is very high and is associated with severe intensity patterns, a very high frequency of replicative nightmares and a low response to conventional therapies.

What participants receive

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

  • Sleep recordingBehavioural

    Sleep is recorded at home during 7 nights in a row using a connected headband. The participant also has to fill in a sleep agenda every day.

  • Cognitive tasksBehavioural

    Working memory and inhibition capacity is assessed during computer-based tasks (2-back and Go/No-Go tasks) at enrollment and 1 month after enrollment.

  • QuestionnairesOther

    The participant has to fill in several questionnaires at enrollment and 1 month after enrollment in order to assess:

    • PTSD severity
    • chronotype
    • Sleep quality
    • Daytime sleepiness
    • Mood state
    • Depression
    • Mental disorders and their consequences

What is being measured

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

  1. Proportion of subjects with a Sleep Efficiency Index (SEI) < 80%.

    The sleep efficiency index (SEI) is defined by the ratio TST/TIB with TST being Total Sleep Time and TIB being Time In Bed.

    TST and TIB will be assessed objectively, at home, using a connected headband (DREEM®, Rythm Paris).

    A Sleep Efficiency Index (SEI) < 80% is considered to be a poor quality, low-efficiency night.

    Measured: 1 month after enrollment

The record says: status not confirmed, as of the sponsor's last update on 18 Sep 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 6 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.

Are results available for this study?

Results are not available in the source record.

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

Contact Emeric SAGUIN, MD (143985440 ext. +33, emeric.saguin@intradef.gouv.fr), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Proportion of subjects with a Sleep Efficiency Index (SEI) < 80%. (time frame: 1 month after enrollment). 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 NCT04581850, which also lists 2 linked publications.

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?
