About this study

Official title: The Effects of MDMA on Sleep Architecture, Water Homeostasis and Cognitive Function

The purpose of this study is to measure the effects of MDMA on sleep, mood, thinking, and how your body retains water. The researchers are interested in the effects that occur a few hours after taking MDMA as well as effects occurring over the next two days. We will study these effects in a standardized, controlled setting at the Clinical and Translational Science Institute (CTSI) Clinical Research Center (CRC) located at San Francisco General Hospital.

The primary hypotheses are:

Read more
  1. MDMA will induce sleep disruption, as indicated by comprehensive polysomnography, wrist actigraphy, and self-report sleep measures
  2. MDMA will alter sodium and water homeostasis by either increasing or blunting the suppression of arginine vasopressin levels and decreasing free water excretion. Effects will be exacerbated by water loading.

Secondary hypotheses:

  1. Acutely, MDMA will increase both positive and negative arousal, and to increase sociability but not autonomy.
  2. Acutely, MDMA will increase risk-taking and willingness to donate money to others in an economic decision making task.
  3. MDMA will decrease the stressful effects of talking about a negatively-valenced autobiographical but will increase recall for details for these episodes.
  4. MDMA will increase oxidative stress markers and possible ameliorating factors (e.g., ADMA).
  5. The short form of the serotonin transported promoter region will be associated with greater acute and discontinuation effects of MDMA.
Read the detailed description

This is a placebo-controlled, double-blind, gender balanced, within-subject study on the acute and 24 to 48 hour post dose effects (discontinuation syndrome) of MDMA on sleep architecture, water homeostasis and neurocognitive function. We will define the signs and symptoms of sleep disruption and time course of alterations in ADH levels and neurocognitive function occurring after administration of a single dose of MDMA in experienced users. The immediate effects of MDMA include euphoria and intoxication; at 24 hours after MDMA these positive effects are replaced by lowered mood and lethargy - we refer to these effects as a discontinuation syndrome. The pleasurable effects of MDMA are thought to be due to elevations of serotonin, norepinephrine and dopamine; the mechanisms of post-MDMA depression are unknown but may be due to relative serotonin depletion. Among its many functions serotonin maintains normal sleep architecture. The effects of MDMA discontinuation on sleep architecture will be assessed using comprehensive polysomnography and wrist actigraphy with measures obtained ~36 hours after a single dose of MDMA. Cognitive measurements will explore the acute effects of MDMA. MDMA can produce hyponatremia. In this study we will evaluate the effects of MDMA on ADH release, urine sodium excretion, and the relationship of gender to these effects.

What is being measured

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

  1. Time course, severity, and characteristics of MDMA discontinuation in experienced MDMA users given a known dose of MDMA

    Measured: 1 hour post dose through 48 hours post dose

  2. Relate observed discontinuation effects to sleep data: polysomnography, wrist actigraphy, and self-report sleep measures.

    Measured: 1 hour post dose through 48 hours post dose

  3. Assess the acute effects of MDMA on water and sodium homeostasis

    Measured: 1 hour post dose through 48 hours post dose

Secondary outcomes (4)
  1. Document the acute effects of MDMA on self-reported measures, including positive and negative arousal, autonomy, and sociability.

    Measured: 1 hour post dose through 48 hours post dose

  2. Document the acute effects of MDMA on behavioral measures of economic decision making.

    Measured: 1 hour post dose through 48 hours post dose

  3. Document the acute effects of MDMA on autobiographical speech and memory

    Measured: 1 hour post dose through 48 hours post dose

  4. Measure the effects of MDMA on ADMA

    Measured: 1 hour post dose through 48 hours post dose

Questions about this trial

What is this clinical trial studying?

A study of MDMA Discontinuation Syndrome, run by California Pacific Medical Center Research Institute 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 9 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 31 May 2013. 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?

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?

Time course, severity, and characteristics of MDMA discontinuation in experienced MDMA users given a known dose of MDMA (time frame: 1 hour post dose through 48 hours post dose). The study lists 3 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 31 May 2013.
