Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 20 to 70 years
  • All sexes
  • Healthy volunteers accepted
  • Adult, Older adult

Study population: 1. Healthy Controls: The healthy controls will be recruited from the local community, or the neurological clinic. The cognitive performance will be evaluated by Mini-Mental State Examination (MMSE). A complete physical and neurological examination will be performed. 2. Huntington Disease: Patients with Huntington Disease will be referred from the department of neurology in ChangGung Memorial Hospital, LinKou. Established diagnosis will be made by a neurological examination and genetic assessment of CAG expansion in the Htt gene. The severity and progression of the disease will be assessed by the Unified Huntington's Disease Rating Scale (UHDRS) (18). The cognitive performance will be evaluated by Mini-Mental State Examination (MMSE). The inclusion criteria are the following:

Who may be able to join

  • Huntington Disease
  • All participants should be aged between 20 and 70 year old.

  • Able to understand and provide signed informed consent.
  • Healthy Controls:
  • Able to understand and provide signed informed consent
  • age range and gender matched with Patients with HD
  • without significant neuropsychiatric disorders

Who cannot join

  • Human Subjects The participants will be divided into 2 groups: Huntington Disease Group and Healthy Control Group. All participants should be aged between 20 and 70 year old, right handed and gender balanced.
  • Exclusion CriteriaThe following exclusion criteria apply to both groups.
  • Cardiac pacemaker implantation.
  • Implantation of intracranial metal device.
  • Significant major systemic disease, such as renal failure, heart failure, stroke, AMI/unstable angina, poor controlled diabetes mellitus, poor controlled hypertension.

  • Severe dementia.
  • Any documented abnormality of brain caused by etiologies other than HD by MRI and 18FDG PET studies, which might contribute to the cognitive function, such as hydrocephalus or encephalomalacia, will be excluded. Mild cortical atrophy will be allowed.
  • History of intracranial operation, including thalamotomy, pallidotomy, and/or deep brain stimulation.
  • Significant physical disorder or neuropsychiatric disorder.

About this study

Official title: Accelerated Diffusion MRI as a Potential Image Based Biomarker for Hungtington Disease

The hypotheses of the project are

  1. Diffusion MRI using compressed sensing could have reduced motion sensitivity and improved susceptibility related artifact because of accelerated acquisition.
  2. The macromolecule deposition in the brain of patients with Huntington Disease (HD) can lead to changes detectible by diffusion MRI.

To validate the hypothesis that the new accelerated diffusion MRI technique could produce a new biomarker for HD, patients with Huntington Disease will be recruited. The diffusion index will be calculated using accelerated acquisition. The diagnostic performance will be evaluated for data reconstructed with and without acceleration. The correlation with the disease severity will be assessed.

Read the detailed description

Diffusion magnetic resonance imaging has emerged as a sensitive, noninvasive tool for assessing the abnormalities in the central nervous system. Applications have been reported in many neurological disorders. However, because of the motion-sensitizing diffusion gradient and the prolonged diffusion encoding time, clinical practice could be difficult especially in patients with motor disorders such as Huntington Disease. Currently there existed no useful biomarker which could reflect either the disease progression or severity of Huntington disease. There is a growing interest in imaging Huntington disease using diffusion magnetic resonance imaging because of its capability to depict the micro-environmental changes.

Unfortunately the excessive motor abnormality such as chorea yields the acquisition of diffusion magnetic resonance imaging unfeasible in a clinical setting. The diffusion MRI with compressed sensing demonstrated reduced motion sensitivity and improved susceptibility related artifact because of the accelerated acquisition. Because of the reduced acquisition time, diffusion MRI in patient with Huntington Disease would be possible. It is therefore expected that the macromolecule deposition in the brain of patients with HD can lead to detectible changes in diffusion properties. The accelerated diffusion MRI techniques will be used to acquire data from healthy volunteers and patients with Huntington disease. The aim of the study is to develop and optimize a novel accelerated diffusion Magnetic Resonance Imaging (MRI) technique using advanced compressed sensing techniques. The joint sparsity constraint algorithm will be implemented in an in-line reconstruction platform for the diffusion MRI processing.

The second aim is to test the efficiency of the new accelerated diffusion MRI technique from phantom and in healthy human. Finally to validate the hypothesis that the new accelerated diffusion MRI technique could produce a new biomarker for HD, patients with Huntington Disease will be recruited. The diffusion index will be calculated using accelerated acquisition. The diagnostic performance will be evaluated for data reconstructed with and without acceleration. The correlation with the disease severity will be assessed. A risk management report will be concluded at the end of project execution for registration in the department of health. The acceleration diffusion MRI could provide new insight to the etiology of the disease. The in-line image reconstruction platform could be used for pediatric or psychiatric patients who cannot hold still in the scanner for a prolonged period and in patients with movement disorders.

What is being measured

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

  1. Feasibility study on healthy human.

    Procedure:

    Diffusion MRI will be acquired form healthy volunteers.

    Approach:

    Images will be acquired with and without compressed sensing DTI The reproducibility of compressed sensing diffusion MRI will be assessed in human

    Measured: the 30th month

Secondary outcomes (1)
  1. Diagnosis Huntington Disease

    Procedure:

Questions about this trial

What is this clinical trial studying?

An observational study of Huntington Disease, run by Wang . Jiun-Jie at 1 site in Taiwan.

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 8 inclusion and 10 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 18 Jul 2018. 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 Taiwan. 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?

Feasibility study on healthy human. (time frame: the 30th month). 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 18 Jul 2018.
