About this study

The overall purpose of this project is to evaluate the effect of sertraline administration on the binding of 123-I mZINT in 10 healthy subjects. All study procedures will be conducted at the Institute for Neurodegenerative Disorders (IND) and Molecular NeuroImaging (MNI) in New Haven, CT.

Read the detailed description

Serotonin (5-HT) is a monoamine neurotransmitter found in the peripheral and central nervous system. It is responsible for regulating a wide variety of physiological processes and higher CNS functions. 5-HT neurons project diffusely throughout the brain, innervating the cerebral cortex, hippocampus, thalamus, midbrain, brainstem and cerebellum, and play a prominent role in regulating physiological and behavioral responses such as arousal, thermoregulation, anxiety, and affect.

All subjects will undergo written informed consent and a screening evaluation including baseline clinical laboratory testing, and a baseline physical and neurological evaluation. healthy subjects will undergo a baseline 123-I MZINT injection and SPECT imaging described below. At baseline, healthy subjects will be started on either no treatment (n=4), or one of three different doses of sertraline (25 mg/day n=2, 50 mg/day n=2 or 150 mg/day n=2), which will be administered over a 14 day period. Fourteen days following imaging session 1, all subjects (treated with sertraline and untreated) will undergo a second 123-I MZINT and SPECT imaging study. Data from the baseline and follow-up SPECT images will be compared to evaluate for any effect of sertraline on regional brain uptake of 123-I MZINT. The subjects that are randomized to no treatment will serve as controls and provide preliminary test-retest reproducibility data on the imaging outcome measure.

The goal of this proposal is to evaluate the effect of sertraline administration on the specific [123-I] mZINT. In vitro and in vivo data from early human studies and baboon studies strongly support further evaluation of [123I] mZINT in healthy subjects.

  • 123-I MZINT injection and SPECT imagingDrug

    SPECT imaging uses the single photon emissions from radioactive compounds that are (most commonly) injected into a patient and are metabolized by specific organs or body systems. SPECT imaging is performed by using a gamma camera to acquire multiple 2-D images (also called projections), from multiple angles. A computer is then used to apply a tomographic reconstruction algorithm to the multiple projections, yielding a 3-D dataset. This dataset may then be manipulated to show thin slices along any chosen axis of the body, similar to those obtained from other tomographic techniques, such as MRI, CT, and PET. The resulting SPECT images reflect body/organ function as opposed to specific anatomy of other imaging modalities such as CT or MRI

What is being measured

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

  1. Does administration of sertraline have an effect on the specific binding of 123-mZINT in healthy subjects evaluated with serial, dynamic SPECT imaging at baseline and after 14 days of sertraline treatment?

    Measured: 14 DAYS

Secondary outcomes (1)
  1. Is there a dose effect of sertraline on 123I MZINT binding? Do higher doses of sertraline have a more profound effect on the specific binding of 123I MZINT than lower doses of sertraline?

    Measured: 14 DAYS

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing 123-I MZINT injection and SPECT imaging in people with Depression, run by Institute for Neurodegenerative Disorders 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 5 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: stopped early, as of the sponsor's last update on 3 Apr 2019. 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?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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 was stopped early. 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?

Does administration of sertraline have an effect on the specific binding of 123-mZINT in healthy subjects evaluated with serial, dynamic SPECT imaging at baseline and after 14 days of sertraline treatment? (time frame: 14 DAYS). 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 NCT00470925, 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 3 Apr 2019.
