Trial summary

Neuropsychiatric manifestations of Systemic Lupus Erythematosus (NPSLE) are both common and an important source of morbidity. Of the case definitions for NPSLE syndromes that have recently been developed, cognitive dysfunction appears to be the most prevalent. Read more about this study

About this study

Neuropsychiatric manifestations of Systemic Lupus Erythematosus (NPSLE) are both common and an important source of morbidity. Of the case definitions for NPSLE syndromes that have recently been developed, cognitive dysfunction appears to be the most prevalent. A novel mechanism is that a subset of SLE patients with cognitive dysfunction have antibodies in the NR2 glutamate receptor. We propose, in a double -blind placebo-controlled trial, to determine whether SLE patients, with or without the NR2 glutamate receptor antibody, have significant improvement using memantine, an inhibitor of the NMDA receptor.

Read the detailed description

Patients with SLE frequently report cognitive and memory problems and many studies have documented significant cognitive deficits with traditional neuropsychological test batteries. Many traditional neuropsychological tests are unsuitable for repeated measures over short intervals caused by expected improvement due to test-retest or practice effects. We will utilize an automated battery (ANAM) of cognitive function tests at baseline, 6 weeks, and 12 weeks, as the outcome measure.

Betty Diamond M.D. and colleagues demonstrated that a subset of lupus anti-DNA antibodies cross-reacts with the NR2 glutamate receptor in patients with SLE. Glutamate receptors can display altered expression in major psychosis and over-stimulation of NR2 can cause excitotoxic neuron death through excessive entry of calcium into cells. Thus, antibody reactivity with NR2a or NR2b may not only serve as a marker for CNS disease in SLE but may also be neuropathogenic mechanism for some of the non-focal CNS disturbances in SLE.

Memantine is a low- to moderate-affinity, noncompetitive N-methyl-D-asparate (NMDA) receptor that represents the first member of a new class of medications showing clinical benefit and good tolerability in Alzheimer's Disease. Because of our anecdotal experience with some SLE patients with cognitive impairment improving with donepezil therapy, an approved Alzheimer's Disease therapy, and because of the known association of cognitive impairment in SLE with anti-NR2 glutamate (NMDA) receptor antibodies, we hypothesize that memantine will have benefit for cognitive dysfunction in SLE.

We believe that computerized cognitive function batteries (ANAM) can be used in clinical trials of cognitive impairment, with the benefit of efficiency, immediate results, and less patient time. However, because this is the first clinical trial of this kind in SLE, we will also use the formal American College of Rheumatology neuropsychiatric battery, as well

Questions about this trial

What is this clinical trial studying?

A study testing Memantine in people with Systemic Lupus Erythematosus, run by Johns Hopkins 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 2 inclusion and 8 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 7 Mar 2008. 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. Some participants in this study may receive a placebo. 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 ANAM, Version 3.11 (time frame: 12 Weeks). 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 7 Mar 2008.
