Primary Outcome Measures:
  • Yale Brown Obsessive Compulsive Scale Modified for KM (KM-YBOCS) [ Time Frame: Week 8 (last visit) ]
    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 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.

Secondary Outcome Measures:
  • Kleptomania Symptom Assessment Scale (K-SAS) [ Time Frame: Week 8 (last visit) ]
    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.

  • Clinical Global Impression Severity Scales (CGI) [ Time Frame: Week 8 (last visit) ]
    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.

Enrollment: 12
Study Start Date: March 2009
Study Completion Date: June 2012
Primary Completion Date: May 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Memantine
Memantine 10-30mg
Drug: Memantine
10-30mg, daily for 8 weeks
Other Name: Namenda

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.

Ages Eligible for Study:   18 Years to 65 Years   (Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  1. men and women age 18-65
  2. current KM using the clinician-administered Structured Clinical Interview for Kleptomania (SCI-K)
  3. stealing behavior within 2 weeks prior to enrollment.

Exclusion Criteria:

  1. infrequent stealing (i.e. less than one time per week) that does not meet proposed criteria for KM
  2. unstable medical illness or clinically significant abnormalities on laboratory tests or physical examination at screen
  3. history of seizures
  4. myocardial infarction within 6 months
  5. current pregnancy or lactation, or inadequate contraception in women of childbearing potential
  6. a need for medication other than memantine with possible psychotropic effects or unfavorable interactions
  7. clinically significant suicidality
  8. current Axis I disorder determined by the SCID and SCID-compatible modules for impulse control disorders (Grant et al., 2005), except for nicotine dependence
  9. lifetime history of bipolar disorder type I or II, dementia, schizophrenia, or any psychotic disorder determined by SCID
  10. current or recent (past 3 months) DSM-IV substance abuse or dependence
  11. positive urine drug screen at screening
  12. initiation of psychotherapy or behavior therapy within 3 months prior to study baseline
  13. previous treatment with memantine; and 14) treatment with investigational medication or depot neuroleptics within 3 months, with fluoxetine within 6 weeks, or with other psychotropics within 2 weeks prior to study baseline.
