Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Have participated in and completed the NBI-98854-1501 (T-Force Green) or NBI-98854-1505 (T-Forward) Phase 2 study
  • Have a clinical diagnosis of Tourette Syndrome (TS)

  • Subjects of childbearing potential who do not practice total abstinence must agree to use hormonal or two forms of nonhormonal contraception (dual contraception) consistently during the screening, treatment and follow-up periods of the study
  • Adolescent and adult subjects (12 to 64 years of age) must have a negative urine drug screen for amphetamines, barbiturates, benzodiazepine, phencyclidine, cocaine, opiates, or cannabinoids and a negative alcohol screen. Subjects who are on stable doses of prescribed and supervised (not as needed) benzodiazepines, opiates, or psychostimulants (for subjects with comorbid ADHD) are allowed to participate in the study

  • Have a known history of long QT syndrome or cardiac arrhythmia
  • Have a known history of neuroleptic malignant syndrome
  • Have a cancer diagnosis within 3 years prior to screening (some exceptions allowed)
  • Have a blood loss ≥250 mL or donated blood within 56 days prior to screening (subjects 6 to 17 years of age); have a blood loss ≥550 mL or donated blood within 30 days prior to screening (subjects 18 to 64 years of age)
  • Have a known history of substance dependence, substance (drug) or alcohol abuse
  • Have a significant risk of suicidal or violent behavior
  • Have initiated Comprehensive Behavioral Intervention for Tics (CBIT) during the screening period or at baseline or plan to initiate CBIT during the study
  • Have received an investigational drug within 30 days before screening or plan to use an investigational drug (other than NBI-98854) during the study
