Brief Title
Evaluation of Safety and Tolerability of Long-term TEV-50717 (Deutetrabenazine) for Treatment of Tourette Syndrome in Children and Adolescents
Official Title
An Open-Label, Long-Term Safety Study Including a Double-Blind, Placebo-Controlled, Randomized Withdrawal Period of TEV-50717 (Deutetrabenazine) for the Treatment of Tourette Syndrome in Children and Adolescents
Brief Summary
This is an otherwise open-label, single-arm study that includes a 2-week, double-blind,
placebo controlled, randomized drug withdrawal period followed by a 3 week blinded
maintenance or re-titration, and then a maintenance period. This study aims to evaluate the
safety and efficacy of TEV-50717 tablets in patients with tics associated with TS who have
previously completed participation in any of the parent studies.
Detailed Description
This is an otherwise open-label, single-arm study (Part A) that includes a 2-week,
double-blind, placebo controlled, randomized drug withdrawal period (Part B) followed by a 3
week blinded maintenance or re-titration (Part A resumed), and then a maintenance period.
This study aims to evaluate the safety and efficacy of TEV-50717 tablets in patients with
tics associated with TS who have previously completed participation in any of the parent
studies (SD-809-C-17 [Phase 1b], TV50717-CNS 30046 [Phase 2/3], or TV50717-CNS 30060 [Phase
3]).
