About this study

Official title: Clinical Studies of Mental Illness Not Involving Treatment Development, Efficacy, or Effectiveness Trials Phenotype-genotype Predictors of Cognitive Outcomes in Geriatric Depression

Late-life depression (LLD) and cognitive impairment (CI) are significant public health problems among older adults, and their co-occurrence markedly increases disease burden and dementia risk. This highlights the importance of identifying and treating CI in LDD; however, current lack of reliable prognostic information from clinical, neuroimaging, and genetic data impedes research on targeted prevention and treatment. Two critical ways to close current knowledge gaps in predicting cognitive diagnostic outcomes of LLD involve: 1) increasing the number of diagnostic cases available to existing studies, and 2) using those studies to identify clinical, imaging, and genetic predictors that will improve future diagnosis. We intend to do both in the current proposal. We plan to study the following SPECIFIC AIMS:

Aim 1: Identify baseline clinical-behavioral predictors of cognitive diagnostic outcomes in LLD.

Working hypothesis: During acute LLD, CN will be associated with more frequent EOD and higher negative life stress than PCI and AD; PCI will be associated with EOD and higher frailty than CN and AD; AD will be associated with LOD, greater appetite loss, lower anxiety, and greater memory impairment than CN and PCI.

Aim 2: Use multimodal neuroimaging at baseline to identify patterns associated with cognitive diagnostic outcomes in individuals with LLD. Working Hypothesis: CN will be associated with greater white matter integrity compared with PCI and AD; PCI will be associated with lower white matter integrity and network abnormalities in anterior cingulate cortex compared with CN; AD will be associated with lower hippocampal volume compared with CN and PCI.

Aim 3: (exploratory): Explore interrelationships among candidate genes, cognitive diagnostic outcomes, and proposed phenotypic components relevant to LLD. Exploratory Hypotheses: 1) COMT val158met polymorphism will be associated with CN; 2) 5-HTTPRL and APOE ε2 polymorphisms will be associated with frailty; 3) genetic variation (SNPs) in TPH2 and AGTR1 will be associated with risk factors of AD: LOD, episodic memory, hippocampal volume, and appetite loss.

Read the detailed description

Central hypothesis: the 5-year likelihood of each cognitive diagnostic outcome is associated with distinct clinical, cognitive, and neural phenotypes during acute LLD, which in turn have distinct genotypic correlates.

Specifically, CN individuals will have earlier first onset of depression (EOD) relative to AD, more negative life stress during acute depression compared with AD and PCI, and greater white matter integrity; CN will also be associated with the AA genotype of the COMT val158met polymorphism, which may confer both neuroprotection and higher stress sensitivity. PCI will have more EOD relative to AD, greater frailty, and lower white matter integrity than NC. AD will be associated with later age of depression onset (LOD), greater appetite loss, lower anxiety, smaller hippocampal volume, and greater memory impairment. To test these hypotheses, we propose the following

What is being measured

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

  1. Change in Depression status (measured by Montgomery Asberg Depression Rating Scale)

    Measured: Minimum of once per year, up to 21 years

  2. Change in Cognitive impairment (as measuring using cognitive tests including those found in the CERAD battery)

    Measured: Once per year, up to 21 years

  3. Development of dementia (Determined by Clinical Consensus Conference)

    Measured: once per year, up to 14 years

Secondary outcomes (3)
  1. Change in Cognition (as measured by tests including those in the CERAD battery) Change in Brain MRI markers (e.g., volume of white matter and gray matter lesions)

    Measured: once per year, up to 21 years

  2. Change in Impairment in Instrumental or Basic Activities of Daily Living

    Measured: at least once per year, up to 21 years

  3. Packing density of prefrontal cortex neurons with pyramidal morphology in post-mortem neuroanatomical studies

    Measured: once post-mortem

Questions about this trial

What is this clinical trial studying?

An observational study of Major Depression and Dementia, run by Duke University 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 11 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: finished, as of the sponsor's last update on 5 Aug 2020. 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.

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?

Change in Depression status (measured by Montgomery Asberg Depression Rating Scale) (time frame: Minimum of once per year, up to 21 years). The study lists 3 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 NCT00570583, which also lists 3 linked publications.

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 5 Aug 2020.
