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 10 years and older
  • All sexes
  • No healthy volunteers
  • Child, Adult, Older adult

Who may be able to join

  • Patients with a family history of early-onset progressive dementia or decline in cognition and neuronal inclusion bodies which are immunohistopathologically consistent with neuroserpin inclusion bodies.
  • Children with progressive dementia and myoclonic epilepsy which is consistent with the reported clinical course in pediatric patients or children with the clinical phenotype who on autopsy demonstrate neuronal inclusion boidies which are immunohistopathologically consistent with neuroserpin inclusion bodies.
  • Family members at risk, of at least 18 years of age, including first degree relatives of affected patients and the adult offspring of these first degree relatives.
  • In rare instances probands and their at risk family members with known presenile dementia and a neurologic course typical of that seen in FENIB will be enrolled.
  • We may also enroll offsite individuals who have any of the above findings, but are too medically fragile to travel to the Clinical Center and for whom a durable power of attorney (DPA) is available. The physical examination and laboratory research studies will be performed by the Investigator(s) and all clinical studies will be done in a local accredited hospital.
  • Family members either not at risk and unaffected spouses may enroll primarily for genetic linkage information. These individuals will contribute a blood sample for molecular analysis only. Those unwilling to travel may also provide a blood sample only. No clinical studies will be performed on individuals from this category.

Who cannot join

  • Another diagnosis of presenile demential is made by a physician including but not limited to: 1) Huntington Disease, 2) Parkinson Disease/Diffuse Lewy Body Disease, 3) Familial Alzheimer Disease with known mutations in presenilin 1, presenilin 2 or beta-amyloid precursor protein, 4) Lafora Body Disease, 5) Pick's Disease, and 6) fronto-temporal dementia.
  • A Durable Power of Attorney is not available in a human subject that is not medically competent to give consent.

About this study

Official title: Clinical, Molecular and Biochemical Characterization of Familial Encephalopathy With Neuroserpin Inclusion Bodies

The purpose of this study is to learn more about the medical problems and the genetic factors involved in a recently defined form of inherited dementia called "familial dementia with neuroserpin inclusion bodies (FDNIB)." Abnormal substances in nerve cells of patients with this disease affect brain and nervous system function, causing confusion, memory decline and impaired cognition (thinking ability). Patients also develop movement disorders and, possibly, seizures. Symptoms begin in midlife, between 45 and 55 years of age.

Patients with FDNIB and family members 18 years of age or older at risk for the disease may be eligible for this 3-year study.

Participants will have a medical and family history and review of medical records; interview with a medical geneticist (specialist in genetics); physical, neurological and psychiatric examinations; and the following tests and procedures:

  1. Blood tests to assess general health
  2. Chest and skull X-rays
  3. Electrocardiogram (EKG)-record of the electrical activity of the heart using electrodes placed on the chest
  4. Electroencephalogram (EEG)-record of the electrical activity of the brain using electrodes placed on the head
  5. Ultrasound of the abdomen-imaging of abdominal organs using sound waves
  6. Brain magnetic resonance imaging (MRI)-imaging of the brain using a strong magnetic field and radio waves
  7. Hearing evaluation
  8. Assessment of performance of daily living activities
  9. Single photon emission computed tomography (SPECT)-imaging of brain metabolism and blood flow using a radioactive substance injected into a vein

The evaluation will be done over a 3- to 4-day period. At their completion, participants will meet with a physician and a genetics counselor to discuss the clinically significant findings. Participants may be asked to return for follow-up evaluations every 6 months to a year (depending on the individual's condition) for 3 years.

Read the detailed description

This project involves the study of a novel familial neurodegenerative disorder, familial encephalopathy with neuroserpin inclusion bodies (FENIB). This disorder, which has a characteristic clinical course of progressive dementia and neurologic involvement, was initially defined in one extended family. Neuroserpin is the gene for this disorder and a mutation is present in this large kindred and four additional families/cases. This protocol will characterize the clinical phenotype, delineate the natural history of the disorder and explore genotype/phenotype correlations in the index family and possibly in other reported cases. Families with immunohistopathologically-neuroserpin positive neuronal inclusions on autopsy/biopsy in an affected member(s), neuroserpin mutation-positive proband, or with familial presenile dementia with neurologic features consistent with the original FENIB family will be enrolled.

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 6 inclusion and 2 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 2 Jul 2017. 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.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00006176, 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 2 Jul 2017.
