Memantine in Body Focused Repetitive Behaviors

Trichotillomania (Hair-Pulling Disorder) Clinical Trial

Official title: A Double-Blind, Placebo-Controlled Study of Memantine in Body Focused Repetitive Behaviors

Status Completed

Clinical Trial Summary

This study is 8 weeks long and involves subjects taking memantine or placebo. If they are randomly assigned to the memantine arm and are eligible to participate in the study, they will begin by taking 10mg once daily of memantine for two weeks, then 20mg for the remaining six weeks. Efficacy and safety measures will be performed at each visit. Participants will be randomized to receive either memantine or placebo on a 1:1 basis. This blinding will be maintained by the IDS pharmacy at the University of Chicago.

Clinical Trial Description

The goal of the proposed study is to evaluate the efficacy and safety of memantine in 100 subjects with DSM-5 trichotillomania (TTM) or skin picking disorder (SPD).

The hypothesis to be tested is that memantine will be more effective and well tolerated in adults with trichotillomania or skin picking disorder compared to placebo. The proposed study will provide needed data on the treatment of a disabling disorder where there are not any current treatments options.

This will be one of few studies assessing the use of pharmacotherapy for the treatment of TTM and SPD in adults. Assessing the efficacy and safety of memantine will help inform clinicians about additional treatment options for adults suffering from this disorder. ;
