Primary Outcome Measures :
  1. Severity of tic symptoms assessed by Yale Global Tic Severity Scale (YGTSS) [ Time Frame: Week 12 ]
    The YGTSS is designed to rate the overall severity of motor and phonic tic symptoms across a range of dimensions: number, frequency, intensity, complexity, and interference. The scale also includes an impairment assessment. The YGTSS total tic score (TTS) will be the primary measure for this study and represents the sum of the 5 subcategories (number, frequency, intensity, complexity, and interference) for both motor and phonic tics, each scored from 0 to 5, with higher values representing a worsening assessment.


Secondary Outcome Measures :
  1. Overall improvement of Tourette Syndrome with Clinical Global Impression-Tourette Syndrome (CGI-TS-Improvement) [ Time Frame: Week 12 ]

  3. Have a known history of neuroleptic malignant syndrome
  4. Have a cancer diagnosis within 3 years prior to screening (some exceptions allowed)
  5. Have an allergy, hypersensitivity, or intolerance to VMAT2 inhibitors
  6. Have a blood loss ≥250 mL or donated blood within 30 days prior to screening
  7. Have a known history of substance dependence, substance (drug) or alcohol abuse
  8. Have a significant risk of suicidal or violent behavior
  9. Have initiated Comprehensive Behavioral Intervention for Tics (CBIT) during the screening period or at baseline or plan to initiate CBIT during the study
  10. Have received an investigational drug within 30 days before screening or plan to use an investigational drug (other than NBI-98854) during the study
