Trial summary

The overall plan of this project is to evaluate [123I] mZINT as a tool to assess SERT density in humans. This protocol will be completed in three parts. In Part A serial dynamic SPECT will be acquired after injection of [123I] mZINT in healthy controls to assess regional brain uptake in human subjects. Read more about this study

About this study

Official title: Phase I Evaluation of (123-I)MZINT as a Brain SPECT Tracer of Serotonin Transporters in Healthy Human Subjects

The overall plan of this project is to evaluate [123I] mZINT as a tool to assess SERT density in humans. This protocol will be completed in three parts. In Part A serial dynamic SPECT will be acquired after injection of [123I] mZINT in healthy controls to assess regional brain uptake in human subjects. If Part A demonstrates robust brain region specific uptake, then Part B - additional studies in healthy subjects to assess biodistribution, and Part C - studies in PD subjects to compare regional uptake to healthy controls, will be completed.

Read the detailed description

All study procedures will be conducted at the Institute for Neurodegenerative Disorders (IND) and Molecular NeuroImaging (MNI) in New Haven, CT. Approximately 10 (6 -Part A and 4 - Part B) healthy subjects and 10 PD subjects will be recruited from the IND databases, patient spouses, and the community to participate in this protocol. The study doctor will discuss the study procedures and evaluate the subject for eligibility. All subjects will undergo written informed consent and a screening evaluation including baseline clinical laboratory testing, and a baseline physical and neurological evaluation.

Following bolus intravenous injection of 5 mCi of 123-I mZINT over 15 seconds, serial dynamic SPECT brain acquisitions will be obtained to evaluate the regional brain uptake and washout of activity. Venous blood measures will be obtained with each acquisition and characterization of 123-I mZINT and metabolites will be assessed. Safety assessments will include vital signs, serum chemistries, CBC, urinalysis, and EKG.

Vital signs will be assessed at pre-injection baseline and 15, 30, 60, and 90 minutes following the infusion of 123-I mZINT. An EKG will be obtained at baseline and at 20 and 40 min post 123-I mZINT injection. Adverse events will be assessed when vital signs are obtained. Clinical laboratory tests performed at baseline and after each injection including the following: serum chemistry battery, complete blood count with differential, and urinalysis.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing [123I] mZINT injection and serial dynamic SPECT imaging in people with Parkinson Disease, 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 14 inclusion and 7 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 6 Oct 2010. 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 (reason given: Scan results to date did not show reason to continue with study). 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?

Measurement of 123-mZINT brain uptake and distribution (time frame: 1 yr). The study lists 4 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 6 Oct 2010.
