About this study
The primary purpose is to determine if patients scheduled to receive prescription corticosteroid therapy for inflammatory illnesses who are given either memantine or riluzole pretreatment will show lesser declarative memory impairment than those receiving placebo.
The exploratory purpose is to determine if patients scheduled to receive prescription corticosteroid therapy for inflammatory illnesses who are given memantine or riluzole pretreatment will show a smaller increase in manic/hypomanic symptom severity than those receiving placebo.
Read the detailed description
Twenty five (25) outpatients with pulmonary (e.g. asthma, cystic fibrosis) or rheumatic (e.g. rheumatoid arthritis, dermatomyositis) illnesses scheduled to receive a brief course ("burst") of prednisone will be enrolled. The subjects will be randomized to receive memantine, riluzole or placebo beginning immediately prior to the corticosteroid therapy and continuing for one week. Measures of cognition and mood will be compared between the two groups at baseline, day 3, and day 7.
Demographic information including age, gender, frequency and duration of prior corticosteroid therapy and current anticipated dose and duration will be collected at baseline. Baseline measures of mood will be assessed with the Activation subscale of the Internal State Scale (ISS) (primary measure), Hamilton Depression Rating Scale (17-item version), and Young Mania Rating Scale (YMRS). Cognition will be assessed with the RAVLT (primary measure), Stroop, and Digit Span Backwards. The subjects will be given memantine (10 mg), riluzole (50 mg), or identical appearing placebo 1 tablet daily for 3 days and then at the first follow up appointment (day 3) the dose will be increased to BID if no side effects are reported. The subjects will be reassessed twice, at day 3 and day 7. Mood and cognitive measures will be repeated. The study visits will last approximately an hour and a half. Participants will discontinue memantine when they discontinue prednisone. The RA administering assessments will be blinded at all times. Alternative but equivalent versions of the RAVLT and Digit Span Backwards will be given to minimize practice or learning effects. Current and cumulative corticosteroid dose (mg each day X number of days) will be determined and recorded.
HVLT-R test total words recalled scores will be compared between baseline and exit of the active medication phase and placebo phase using a within subjects design and paired t-tests. Based on our prior experience working with corticosteroid-dependent patients we have found them to be very compliant with clinical treatment. Thus, we do not anticipate large numbers of dropouts or missing data. In the case of missing data we will use the last observation carried forward. In our lamotrigine study in a similar population, we found a change in total words recalled on a word list and on the Stroop. Assuming a similar change with memantine, using double-sided, paired t-tests, we could detect a difference with a change in the placebo group with participants on the HVLT-R and up to with participants on the Stroop. Thus, although this is primarily a pilot study to obtain effect sizes for future, larger trials funded by NIH, it should have power to detect clinically meaningful differences between medication and placebo.

The exploratory purpose is to determine if patients scheduled to receive prescription corticosteroid therapy for inflammatory illnesses who are given memantine or riluzole pretreatment will show a smaller increase in manic/hypomanic symptom severity than those receiving placebo.

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Memantine and Riluzole in people with Mood and Memory Deficit, run by University of Texas Southwestern Medical Center 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 4 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: stopped early, as of the sponsor's last update on 23 Apr 2013. 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.
What does this phase mean?
Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study was stopped early (reason given: Study finished enrollment but data was never sent for publishing.). Results are not available in the source record.
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?
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 23 Apr 2013; AzTrials last refreshed its copy on 6 Nov 2026.
