About this study

30 healthy adults and 30 patients with major depressive disorder, will take part in three single-application pharmacological interventions (GHB vs. Trazodone vs. placebo p.o.) to test potential effects of these drugs on nocturnal memory consolidation. All participants will be assessed with mood state questionnaires, tests of emotional, procedural and declarative memory consolidation, polysomnography, EEG and neuroinflammatory biomarkers. At experimental nights, learning tasks are performed prior to sleep. The next morning, recalling tasks are performed. Each subject will pass through 5 study nights (1 screening, 1 adaptation and 3 experimental nights).

What is being measured

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

  1. slow wave sleep amount

    slow wave sleep time (minutes) during the experimental night

    Measured: 1 night

  2. performance in emotional memory consolidation tasks by Emotional Picture Memory Task (EPMT)

    results in EPMT are measured as number of recognized pictures (1-150)

    Measured: 10 hours after encoding

  3. performance in procedural memory consolidation tasks by Finger Sequence-Tapping Task (FSTT)

    results in FSTT are measured as number of correct sequences typed in 30seconds

    Measured: 10 hours after encoding

  4. performance in declarative memory consolidation tasks by Paired Word List Task (PAWL)

    Results in PAWL are expressed as number of correct word pairs recalled (1-40).

    Measured: 10 hours after encoding

  5. Blood levels of Brain Derived Neurotrophic Factor (BDNF).

    Assessed in serum samples collected by venipuncture using a butterfly needle. Unit of measure as blood concentration (ng/l or mg/ml)

    Measured: 9 hours after solid drug administration

  6. homeostatic sleep pressure by Psychomotor Vigilance Task

    Results are measured in number of correct answers

    Measured: 10 hours after solid drug administration

  7. homeostatic sleep pressure by N-back Task

    Results are measured in number of correct answers

    Measured: 10 hours after solid drug administration

Secondary outcomes (4)
  1. Sleep quality assessed by Morgen Questionionnaire (MQ)

    structured interview about sleep quality on the previous night. Subjektive sleep time will be assessed in minutes (0-480 minutes). Long sleep time will be a good outcome. Interview time of 5minutes.

    Measured: at 8:00 a.m. after experimental night 1,2 and 3

  2. Sleep quality assessed by Karolinska Schläfrigkeitsskala (SKK)

    Subjects will report their subjective sleep pressure in a 1-10 points scale. Low values mean low sleep pressure and better therapy response.

    Measured: at 8:00 a.m. after experimental night 1,2 and 3

  3. Cortisol Saliva Response (CAR)

    Cortisol concetration in Saliva (nmol/l)

    Measured: 0minutes, 15minutes, 30minutes, 45minutes and 60minutes after awekening

  4. Score on Positive and Negative Affect Schedule (PANAS)

    self-report questionnaire that consists of two 10-item scales to measure both positive and negative affect. Each item is rated on a 5-point scale of 1 (not at all) to 5 (very much)

    Measured: 8 hours after solid drug administration

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing GHB and Trazodone in people with Major Depressive Disorder, run by Erich Seifritz at 1 site in Switzerland.

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

Who may be eligible to take part?

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 12 May 2022. 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 Switzerland. 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?

slow wave sleep amount (time frame: 1 night). The study lists 7 primary outcomes in all. 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 12 May 2022.
