Detailed Description:

This is a Phase 2, multicenter, double-blind, placebo-controlled, parallel-group study consisting of a screening period of up to 40 days, a 6 week randomized double-blind treatment period, followed by an up to 2 week safety follow-up period after the last dose of study medication.

Primary Outcome Measures :
  1. Explore the incidence of treatment-emergent adverse events in adults with moderate to severe TTM [ Time Frame: Up to 7 weeks ]
    Safety and tolerability assessed using the frequency of subjects with serious adverse events, adverse events leading to discontinuation, and adverse events judged to be related to study medication.


Secondary Outcome Measures :
  1. Change from baseline hairpulling frequency and severity through 6 weeks [ Time Frame: Up to 7 weeks ]
    Improvement will be assessed using the different measurement parameters of all scales using scales such as the Massachusetts General Hospital Hairpulling scale (MGH-HPS)

  2. Change from baseline hairpulling frequency and severity through 6 weeks [ Time Frame: Up to 7 weeks ]
    Improvement will be assessed using the different measurement parameters of all scales using scales such as the Clinical Global Impression of Severity and Change (CGI-S/C)

  3. Change from baseline hairpulling frequency and severity through 6 weeks [ Time Frame: Up to 7 weeks ]
    Improvement will be assessed using the different measurement parameters of all scales using scales such as the Patient Global Impression of Status and Change (PGI-S/C)

  4. Change from baseline hairpulling frequency and severity daily through 6 weeks [ Time Frame: Up to 7 weeks ]
    Improvement will be assessed using the different measurement parameters of all scales using scales such as the Trichotillomania Symptom Diary (TSD)

  5. Preliminary psychometric evidence of the Trichotillomania Symptom Diary (TSD) will be assessed [ Time Frame: Up to 7 weeks ]
    The reliability, validity and responsiveness of the newly developed TSD assessment will be assessed at the item level.
