About this study

This study will recruit a total of 40 evaluable subjects (20 cognitively depressive, and 20 AD depressive); each evaluable subject involved in this study must fulfill all the inclusion and exclusion criteria according the subject grouping.

Safety measurement will be evaluated by medical history, vital signs, physical examinations, laboratory examinations and collecting of adverse events.

This study is expected to be completed in a period of 3 years.

Read the detailed description

Depression and dementia are the two common psychiatric disorders in the elder subjects. Alzheimer's disease (AD) is the most frequent cause of dementia and about 20% of them have depression. Depression subjects are associated with more rapid cognitive decline, a poorer response to treatment. Post mortem study showed close relationship between AD and disruptions of the serotonergic system, including loss of serotnergic neurons at brain stem. However, the alternations in presynaptic serotonin function relative to demented or non-demented subjects remain to be investigated in living subjects. In this study, the investigators will collect 40 elder subjects (i.e., age above or equal to 50 years old). The serotonin transporter activity will be compared between subjects with or without dementia using I-123 ADAM images. The single photon emission tomography (SPECT) will be compared to recent (within 6 months) F-18 FDG PET images for further investigation.

What is being measured

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

  1. Evaluate the differences of serotonin transporter activity among depressive patient with or without dementia.

    To expand the database of I-123 ADAM SPECT imaging in AD depressive and cognitively depressive patients to refine the definition of a positive scan in patient with AD and MDD.

    Measured: three years

Secondary outcomes (1)
  1. Evaluate the relationship between the serotonin transporter activity and F-18 FDG PET image patter.

    To expand the safety database of I-123 ADAM SPECT imaging Safety variables include adverse event count, lab parameters, vital signs, and ECG. Comparison will be generally made to baseline, as appropriate.

    Measured: three years

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing I-123 ADAM in people with Melancholia, run by Chang Gung Memorial Hospital.

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 4 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 28 Jan 2016. Status can change between updates, so confirm with the study contact before making plans.

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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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 is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Evaluate the differences of serotonin transporter activity among depressive patient with or without dementia. (time frame: three years). 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 28 Jan 2016.
