Trichotillomania (Hair-Pulling Disorder)

This research study is testing the effectiveness and safety of semaglutide (Wegovy) in people with trichotillomania, also known as hair-pulling disorder.

This trial aims to evaluate the efficacy, safety and tolerability of valbenazine, titrated to the subject's optimal dose of 40mg or 80mg, administered once daily, for 12 weeks, for the treatment of trichotillomania (TTM) in a double blind placebo controlled design study. After week 12, subjects will begin a 12-week, open-label portion of the study. During the open-label portion of the study, all subjects will receive the study drug at their optimal dose. The primary endpoint of these studies will be the change from baseline of placebo vs. active scores utilizing the Massachusetts General Hospital Hairpulling Scale (MGH-HPS) at the end of Week 12.

This study is 6 weeks long and involves subjects taking aripiprazole or placebo. If they are randomly assigned to the aripiprazole arm and are eligible to participate in the study, they will begin by taking 5mg once daily of aripiprazole for two weeks, then 10mg once daily for the remaining three weeks. Efficacy and safety measures will be performed at each visit. Participants will be randomized to receive either aripiprazole or placebo on a 1:1 basis. This blinding will be maintained by the IDS pharmacy at the University of Chicago.
