|Teva Announces Breakthrough Therapy Designation for SD-809 Granted by FDA for the Treatment of Tardive Dyskinesia|
Breakthrough Therapy Designation is granted to a drug that is intended to treat a serious condition and preliminary clinical evidence indicates that the drug may demonstrate substantial improvement on a clinically significant endpoint over available therapy or placebo where there is no available therapy. For SD-809, the designation request included results from Teva’s Phase II/III study, Aim to Reduce Movements in Tardive Dyskinesia (ARM-TD). In the ARM-TD study, SD-809 was compared to placebo for change in Abnormal Involuntary Movement Scale (AIMS) score from baseline to end of therapy.

About The ARM-TD Study
The ARM-TD study was a 1:1 randomized, double-blind, placebo-controlled, parallel-group study of 117 patients (104 patients completed the study) with moderate to severe tardive dyskinesia. Enrolled patients received either SD-809 or placebo, which was titrated to optimal dosage over the course of six weeks, and then administered at that dose for another six weeks for a total treatment of 12 weeks. For further details on the ARM-TD study, visit https://clinicaltrials.gov/ct2/show/study/NCT02195700.
The objectives of the study were to evaluate the efficacy of SD-809 in reducing the severity of abnormal involuntary movements associated with tardive dyskinesia and to evaluate the safety and tolerability of titration and maintenance therapy with SD-809 in subjects with tardive dyskinesia.
SD-809 (deutetrabenazine) is an investigational, oral, small molecule inhibitor of vesicular monoamine 2 transporter, or VMAT2, that is designed to regulate the levels of a specific neurotransmitter, dopamine, in the brain. SD-809 is being developed for the treatment of chorea associated with Huntington’s disease, a neurodegenerative movement disorder that impacts cognition, behavior, and movements. Teva is investigating the broad potential of SD-809 for treating additional movements disorders such as tardive dyskinesia and tics associated with Tourette syndrome.
