About this study

Official title: Memantine Treatment of Kleptomania: An Open-Label Study

The goal of the proposed study is to evaluate the efficacy and safety of memantine in kleptomania.

Read the detailed description

The proposed study will consist of 8 weeks of treatment with memantine in 10 subjects with kleptomania. The hypothesis to be tested is that memantine will be effective in reducing the urges to steal in patients with kleptomania. The proposed study will provide needed data on the treatment of a disabling disorder that currently lacks a clearly effective treatment.

Conditions: Kleptomania
Being tested: Memantine
Keywords: Compulsive Stealing, Compulsive Shoplifting
Medical subject headings: Disruptive, Impulse Control, and Conduct Disorders

What participants receive

What is being measured

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

Yale Brown Obsessive Compulsive Scale Modified for Kleptomania (KM-YBOCS)
Scores could range from 0-40 with 0 being the least severe and 40 being the most severe. Here the total score was used. The Yale Brown Obsessive Compulsive Scale Modified for Kleptomania (KM-YBOCS) was completed at every visit (1-5), but the final visit (visit 5) will be the only score reported. The scale was given at baseline and weeks 2, 4, 6, and 8. Only the last visit (week 8) will be reported here.
Measured: Week 8 (last visit)

Secondary outcomes (2)

Kleptomania Symptom Assessment Scale (K-SAS)
Scale used to measure severity of kleptomania. Scores could range from 0-36 with 0 being the least severe and 36 being the most severe. Here the total score was used. The K-SAS was completed at every visit (1-5), but the final visit (visit 5) will be the only score reported. The scale was given at baseline and weeks 2, 4, 6, and 8. Only the last visit (week 8) will be reported here.
Measured: Week 8 (last visit)
Clinical Global Impression Severity Scales (CGI)
The overall impression of the clinician of the severity of the subject. Scores between 1 and 7 with 1 not being ill at all and 7 being one of the worst cases seen. CGI is given at baseline and weeks 2, 4, 6, and 8. Only the last visit (week 8) will be reported here.
Measured: Week 8 (last visit)

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Memantine in people with Kleptomania, run by University of Chicago 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 3 inclusion and 13 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 24 May 2021. 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.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 5 Mar 2014). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Yale Brown Obsessive Compulsive Scale Modified for Kleptomania (KM-YBOCS) (time frame: Week 8 (last visit)). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00880685.

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 24 May 2021; AzTrials last refreshed its copy on 7 Nov 2026.
