About this study

This study will use neuropsychological tests to look at nervous system side effects of Cyclosporine (CsA) in patients with aplastic anemia. CsA is used as part of an immunosuppressive regimen in treating severe aplastic anemia. The drug can produce nervous system side effects, such as tremor and, less commonly, insomnia, anxiety, headache, confusion or seizures. This study will look at effects of CsA on intellectual ability, depression, anxiety, attention, concentration, memory, perception, coordination, and thought processing in patients

Patients 15 years of age or older who have severe aplastic anemia may be eligible for this study if they:

  • are co-enrolled in a Clinical Center protocol in which they will receive CsA
  • have not taken CsA for 6 months before enrolling in this study

Participants undergo neuropsychological testing. In addition, they provide blood samples and their clinical data are reviewed for things that may influence the interpretation of findings from the testing, such as results of blood tests, types of medications taken, number of transfusions required, etc. The procedures are as follows:

Before first dose of cyclosporine:

  • Patients are asked about prior problems with their nervous system, prior treatment for their aplastic anemia (including transfusions), prior infections, and current medications. They then complete the following sets of tests:
  • Battery 1: A set of three tests that measure intellectual ability, level of depression (if any) and level of anxiety (if any).
  • Battery 2: A set of seven tests that measure changes in the central nervous system and how these changes affect attention, concentration, memory, perception, coordination, and thought processing.
  • Patients provide a half teaspoon of blood for this study at the same time blood is collected for their primary treatment protocol. 6 months and 12 months after starting cyclosporine
  • Patients are asked about treatment for their aplastic anemia (including transfusions), infections, and changes in medications that have occurred since they started taking cyclosporine. They then repeat the set of tests in Battery 2.
  • Patients provide a half teaspoon of blood for this study at the same time blood is collected for their primary treatment protocol.
Read the detailed description

Cyclosporine (CsA) is widely used in the treatment of aplastic anemia as well as to provide immunosuppression after transplantation. CsA has a spectrum of neurologic and more subtle, poorly investigated neuropsychological functional effects. In the NHLBI, a unique opportunity exists to evaluate changes in neuropsychological function following CsA in a large cohort of aplastic anemia patients accrued to NHLBI treatment protocols.

With increased success in treating blood diseases with immunosuppressive therapy or stem cell transplantation that utilize CsA in the treatment regimen, patients are enjoying prolonged survival during which quality of life becomes an increasingly relevant concern. We therefore propose this natural history protocol designed to evaluate neuropsychological functioning before, during, and after CsA administration in severe aplastic anemia patients.

The primary objective is to evaluate changes in attention, language, memory, spatial/motor and executive function domains following CsA therapy using well established neuropsychological tests including the Neuropsychological Assessment Battery (NAB) Screening Module, Revised Hopkins Verbal Learning Test, Revised Brief Visual-spatial Memory Test, Judgment of Line Orientation test, Grooved Pegboard, Trail Making Test and the two performance subsets in Wechsler Adult Intelligence Scale-III. IQ test by Wechsler Abbreviated Scale of Intelligence and depression/anxiety level will be screened once prior to formal testing. Measures will also be correlated with clinical status, standard CsA side effects, CsA drug levels and relevant biochemical lab values at each time point to control the testing accuracy and explore potential correlation.

Questions about this trial

What is this clinical trial studying?

An observational study of Aplastic Anemia, run by National Heart, Lung, and Blood Institute (NHLBI) 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 0 inclusion and 6 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 NCT00767650, 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.
