Study summary

This is a single site, randomized, double-blind, placebo-controlled, within-subjects study design in healthy volunteers. Escalating single doses of ITI-214 will be evaluated using functional magnetic resonance imaging (fMRI) to determine central nervous system engagement. Safety and tolerability also will be assessed.

In context

Lead sponsor

Intra-Cellular Therapies, Inc. is the lead sponsor of 41 studies on the registry; 12 are open to participants now.

Of its 24 completed or terminated interventional studies of FDA-regulated products, 11 (46%) have results posted.

First submitted before Intra-Cellular Therapies, Inc. became part of Johnson & Johnson.

Inclusion criteria

  • Healthy male or female, 18 - 45 years
  • Fluent and literate in English and able to provide written
  • between 18.5 and 38.0 kg/m2 and minimum body weight of 50 kg

Exclusion criteria

Exclusion Criteria:

  • Recent exposure to any product
  • Previous exposure to relevant fMRI task(s)
  • Considered medically unsuitable for participation
  • Has any for BOLD fMRI
Terms in these criteria, in plain language(4)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

BMI (body mass index)

Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.

What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

Interventions

What researchers measure

Primary outcomes

  1. BOLD MRI signals in the anterior insula during the extinction phase of a Fear Conditioning task

    Changes in brain activation

    Time frame: 1-3 hours post-dose

  2. BOLD MRI signals in the inferior frontal gyrus during the Stop Signal Task

    Changes in brain activation

    Time frame: 1-3 hours post-dose

Secondary outcomes

  1. BOLD fMRI signals elicited by fear conditioning stimulus

    Changes in brain activation in amygdala, prefrontal cortex, and/or insula cortex

    Time frame: 1-3 hours post-dose

  2. BOLD fMRI signals elicited by the Stop versus Go signal

    Changes in brain activation in dorsolateral prefrontal cortex and/or anterior cingulate cortex

    Time frame: 1-3 hours post-dose

  3. Number of subjects with reported or observed treatment-related adverse events

    Safety and tolerability

    Time frame: 0-5 hours post-dose

Other outcomes

  1. BOLD fMRI signals elicited in the amygdala, insula and medial prefrontal cortex

    Pharmacodynamics

    Time frame: 1-3 hours post-dose

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Nov 6, 2019, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
