About this study

Official title: Eating Disorder Individualized Therapeutics-Naltrexone Neuroimaging (EDIT-N2)

The purpose of this open-label, pilot study is to evaluate fMRI as a biomarker of opioid antagonism in adolescents with ED. Modulation of brain activation will be examined in regions of interest by fMRI using a food-specific and general reward task in adolescents with ED in a pre/post design.

Read the detailed description

This is an open-label, interventional trial to evaluate reward system modulation (detected by neuroimaging) in response to opioid antagonism (i.e., naltrexone) in adolescents aged 13-21 years with an eating disorder characterized by the target behaviors of binge eating and/or purging (e.g., AN-BP, BN, BED). A pre/post design completed on the same day will be employed to quantify within-individual change while reducing potential confounding due to known neuroimaging variables (e.g., menstrual phase, treatment changes) that may occur with time elapsed between study visits. Self-report data regarding will be captured via electronic surveys using validated instruments (where possible), structured interview, study records.

Reward System Modulation by fMRI. Each scan will last approximately 1 hour and involve two reward activation paradigms: passive food view (PFV) and monetary incentive delay (MID). These two reward activation paradigms provide distinct insight and will generate pilot data to support the choice of the optimal paradigm for further testing of reward system modulation in adolescents with eating disorders. PFV provides a paradigm that is relevant to the target behaviors (i.e., binge eating, purging), has been evaluated in ED patients, in response to naltrexone in adults, and is expected to activate food cue-reactivity regions (e.g., prefrontal cortex). MID is a widely used paradigm in adolescents to detect reward anticipation and receipt particularly in the striatum and is currently being used to study the developmental trajectory of reward processing in the longitudinal Adolescent Brain Cognitive Development (ABCD) trial. To the greatest extent possible, we will harmonize our fMRI parameters with those published for ABCD.

Opioid Antagonism and exposure-response linkage. A single oral dose of naltrexone hydrochloride 50 mg tablet will be administered. Plasma and urine will be obtained to measure systemic exposure to naltrexone and it primary, active metabolite, 6-beta-naltrexol, using a validated UPLC-MS/MS assay.

What is being measured

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

  1. Change in % Blood Oxygenation Level Dependent Change (%BOLD) in the Nucleus Accumbens

    Change in %BOLD following single dose naltrexone (post-pre) within individuals during passive food view task in the nucleus accumbens

    Measured: 2 hours post-naltrexone vs baseline

  2. Change in % Blood Oxygenation Level Dependent Change (%BOLD) in the Dorsal Anterior Cingulate Cortex

    Change in %BOLD following single dose naltrexone (post-pre) within individuals during monetary incentive delay in dorsal anterior cingulate cortex

    Measured: 2 hours post-naltrexone vs baseline

Secondary outcomes (1)
  1. Exposure

    Maximum plasma concentration of naltrexone at 2 hours post-single dose

    Measured: 2 hours post-naltrexone

Questions about this trial

What is this clinical trial studying?

A Early Phase 1 study testing Naltrexone in people with Eating Disorders and Binge Eating, run by Children's Mercy Hospital Kansas City 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 3 inclusion and 6 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 12 Oct 2023. 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.

What does this phase mean?

Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 21 Aug 2023). 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?

Change in % Blood Oxygenation Level Dependent Change (%BOLD) in the Nucleus Accumbens (time frame: 2 hours post-naltrexone vs baseline). The study lists 2 primary outcomes in all. 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 NCT04935931, which also lists 1 linked publication.

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 Oct 2023.
