Study population: Subjects are between the age range of 18 to 55, are medically healthy and currently not taking any medications to treat any medical illness, have a history of post-traumatic stress disorder, or are a healthy control who has or has not been exposed to trauma.

  • currently diagnosed with PTSD and symptomatic with a Clinician-Administered PTSD Scale (CAPS) score > 50.
  • age 18-55 years old
  • no personal or first-degree family history of any Axis I diagnosis.

Who cannot join

  • any primary Axis I disorder other than PTSD (e.g. psychosis)
  • medical or neurological illnesses likely to affect physiology or anatomy, i.e. uncontrolled hypertension, cardiovascular disorders
  • a history of drug (including benzodiazepines (BZD)) dependence (Diagnostic and Statistical Manual of Mental Disorders (DSM IV) criteria) within 1 year of the study and lasting longer than 2 years, except for alcohol dependence

About this study

This study uses positron emission tomography (PET) imaging to measure kappa opioid receptors (KOR) in the brains of individuals with and without post-traumatic stress disorder (PTSD). The investigators propose to recruit 45 drug-naïve individuals, N=15 patients with PTSD, N=15 trauma-exposed, but asymptomatic healthy control subjects (TC) and N=15 non-trauma exposed healthy control subjects (HC) to participate in one magnetic resonance imaging (MRI) and one PET study. The investigators will also carefully document trauma history, and collect behavioral and neuroendocrine measures to provide a more integrative view on the neurobiology of PTSD and its phenotype. The investigators predict PTSD will show greater carbon - 11 (11C)[11C]LY2795050 volume of distribution (VT) (i.e. KOR binding) values than control populations in an a priori defined PTSD circuit.

What is being measured

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

  1. Volume of distribution (VT) of cerebral KOR expression in PTSD and healthy control subjects with and without trauma history using the KOR radioligand [11C]LY2795050 and PET

    To examine group differences in cerebral KOR expression in PTSD and healthy control subjects with and without trauma history using the KOR radioligand [11C]LY2795050 and PET.

    Hypothesis: PTSD will show greater [11C]LY2795050 VT (i.e. KOR binding) values than control populations in an a priori defined PTSD circuit.

    Measured: Two months

Questions about this trial

What is this clinical trial studying?

An observational study of Post-traumatic Stress Disorder (PTSD) and Trauma, run by NYU Langone Health 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 26 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: stopped early, as of the sponsor's last update on 20 Jan 2017. 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 was stopped early (reason given: The original PI, Alexander Neumeister, left NYULMC. No data was analyzed.). Results are not available in the source record.

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?

Volume of distribution (VT) of cerebral KOR expression in PTSD and healthy control subjects with and without trauma history using the KOR radioligand [11C]LY2795050 and PET (time frame: Two months). 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 20 Jan 2017.
