NCT05796752

Brief Summary

The goal of the proposed study is to compare the efficacy of behavioral treatment (BT) to memantine, a psychopharmacological agent, for BFRBs. 28 subjects with trichotillomania (TTM) or skin picking disorder (SPD) will receive 8 weeks of memantine treatment, followed by 8 weeks of comprehensive behavioral therapy (ComB) treatment. The hypothesis to be tested is that behavioral therapy will be associated with superior clinical outcomes as compared to memantine. A second hypothesis is that both memantine and behavioral therapy will demonstrate improvement from baseline to the respective posttreatment assessment.

Outcome Measures

Primary Outcomes (1)

  • National Institutes of Mental Health Symptom Severity Scale (for trichotillomania or Skin Picking) (NIMH-TSS or NIMH-SPS)

    The primary efficacy measure will be the change in hair pulling or skin picking frequency and urges to pull hair or pick skin for the past week as indicated by change in total score on the NIMH Symptom Severity Scale (for Trichotillomania or Skin Picking). The primary endpoints will be used to examine differential improvements for memantine vs. BT. Total scores on the NIMH-TSS and NIMH-SPS range from 0-20, with higher scores representing greater severity of trichotillomania/skin picking.

    The primary efficacy endpoints will be the change in these measures from baseline to week 8 in memantine treatment vs. ComB treatment.

Secondary Outcomes (8)

  • Clinical Global Impressions -- Improvement Scale (CGI-I)

    20 weeks

  • Massachusetts General Hospital Hairpulling Scale (MGH-HPS)

Study Arms (1)

Memantine and Behavioral Therapy

EXPERIMENTAL

All subjects will receive 8-weeks of memantine treatment (10mg po qday for the first two weeks, then 20 mg po qday for the remaining six weeks). After the 8-weeks of memantine treatment, the dose will be discontinued. Then, after a 4-week washout period, all subjects will receive 8-weeks of ComB therapy. Therapy will be once a week for 30 minutes. After the 8-weeks of ComB treatment, the therapy will be discontinued.
