Eligibility Criteria
Inclusion Criteria:
- Have documentation of written and witnessed consent from the subject
- Male or female adult between the ages of 18-65, inclusive
- Be in good health as determined by medical history, physical examination, laboratory assessments and 12-lead ECG
- On stable psychiatric medication regime of 4 weeks prior to beginning the trial and not anticipating changes during the trial
- Subjects of child-bearing potential must agree to use contraception (condoms for men, birth control pill or diaphragm for women) consistently from screening until 30 days (female) or 90 days (male) after the last dose of the study drug. A female subject of childbearing potential is defined as a female capable of becoming pregnant, which includes subjects who have had their first menstrual cycle (i.e., menarche) and are not surgically sterile (i.e., bilateral oophorectomy, hysterectomy or bilateral tubal ligation for at least 3 months prior to screening) or have not experienced menopause and subsequently are no longer of childbearing potential.

- Currently pregnant or lactating
- Significant medical comorbidity
- Excessive use of tobacco and/or nicotine-containing products (based on the investigator's assessment or more than 1½ pack of cigarettes per day, 1 can of chewing/dipping tobacco per day, 54mg of nicotine-containing smoking cessation products per day, or any nicotine products or combination of products that exceed 54mg per day) within 30 days of screening
- History of substance (drug or alcohol) dependence or abuse within 3 months before Baseline, as defined by DSM-5 criteria for Substance Use Disorder
- Known history of neuroleptic malignant syndrome
- Known history of long QT syndrome or cardiac arrhythmia
- Have a screening or Day 1 average triplicate ECG corrected QT interval using Fridericia's formula(33) (QTcF) of >450msec or the presence of any clinically significant cardiac abnormality

Outcomes
Primary Outcome Measures
Change in Massachusetts General Hospital Hairpulling Scale (MGH-HPS) from baseline to Week 12
Massachusetts General Hospital Hairpulling Scale (MGH-HPS) scores range from 0-28 with 28 being the most severe. The lower the total score, the lower the severity level. This scale is given and measured once every 2 weeks for a total of 12 weeks.
Secondary Outcome Measures
Clinical Global Improvement Scale - Trichotillomania Severity (CGI-TTM) score at endpoint
Each of the Clinical Global Improvement Scale -Trichotillomania (CGI-TTM) response categories was assigned a numerical score as follows: 1 = Very much improved; 2 = Much improved; 3 = Minimally improved; 4 = Not changed; 5 = Minimally worse; 6 = Much worse; 7 = Very much worse. Responder status on Clinical Global Improvement Scale as having a CGI-TTM score at endpoint less than or equal to 2.

5. Study Description
Brief Summary
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.
Detailed Description
Eligible subjects will be randomized in a double-blind manner in a 1:1 ratio to once-daily doses of valbenazine or placebo for 12 weeks. After week 12, all subjects will begin the 12-week, open-label portion of the study in which they all get their optimal dose. Follow-up assessments will be conducted at the end of week 26 (2 weeks after the last dose of the study drug). For subjects randomized to active treatment, the starting dose will be valbenazine 40mg, which may be escalated to 80mg to achieve an optimal dose of valbenazine for each subject. Dose escalation will occur at the end of week 2 based on the following criteria: 1) the subject's TTM symptoms are not sufficiently controlled per physician investigator assessment and 2) an evaluation by the physician investigator indicates that the subject is tolerating the study drug at the current dose and would likely be able to tolerate the higher dose level. At week 4, the physician investigator may choose to keep the subject at the higher dose or may reduce to the subject's prior tolerated dose (in subjects who have had dose escalation). If a subject's optimal dose was established as 40mg at week 2, no dose escalation will be allowed at week 4. At any time after week 2, the physician investigator may decrease the dose to the previous dose for any subject who had a dose escalation and who is unable to tolerate a given dose increase. The investigator may reduce the subject's dose only one time. Subjects who are unable to tolerate the starting dose or resumption of the 40mg dose will be discontinued from the study. The subject will continue at the dose reached during the optimization period for the remainder of the 12-week treatment period. To maintain the study blind, subjects randomized to placebo in each weight group will be subjected to the same dose escalation requirements, but will receive only placebo during the treatment period. Following the 12-week, double-blind study, all subjects will be offered the option to receive open-label valbenazine for 12 weeks. In order to protect the blind in the first phase of the trial all subjects will receive 40mg of valbenazine from week 12 to week 14 and then be titrated on the study medication similar to the first phase of the trial from that point forward.
