Teva Reports Positive Phase III Tardive Dyskinesia Data


Teva Pharmaceutical Industries Ltd. TEVA announced encouraging top-line data from the second phase III study (AIM-TD) on SD-809 (deutetrabenazine), which is being evaluated for the treatment of tardive dyskinesia (TD).

The randomized, double-blinded, placebo-controlled, parallel-group, fixed-dose study was conducted in patients with moderate-to-severe TD. Results revealed that all three doses (12 mg/day, 24 mg/day and 36 mg/day) of SD-809 demonstrated statistically significant improvement in Abnormal Involuntary Movement Scale scores – the primary endpoint – compared to placebo. Moreover, the 24 mg and 36 mg dose groups showed a significant change from baseline, based on the modified intent-to-treat population at week 12. In addition, improvement was observed on the Clinical Global Impression of change, indicating a reduction in abnormal movements experienced by patients.

Also, SD-809 demonstrated a favorable safety and tolerability profile over the course of the 12-week treatment. The company intends to present a complete analysis at a future medical meeting.

We are encouraged by the recently reported results from the phase III AIM-TD study, which followed positive data from the first phase III ARM-TD trial that were announced this June. Teva plans to file for FDA approval by the end of 2016.


Per the company press release, TD affects approximately 500,000 people in the U.S. There are currently no FDA-approved treatments for this debilitating hyperkinetic movement disorder, representing significant unmet medical need. Hence, there is ample market opportunity for SD-809, upon a potential approval. We note that SD-809 enjoys Breakthrough Therapy status in the U.S. for the treatment of TD.

Teva’s efforts to gain approval for SD-809 for the treatment of chorea associated with Huntington disease suffered a regulatory setback with the FDA issuing a complete response letter (CRL) in May 2016. Teva expects to submit a response to the CRL shortly.

Meanwhile, Teva also plans to evaluate SD-809 for the treatment of tics associated with Tourette syndrome. SD-809 became part of the company’s pipeline following the May 2015 acquisition of Auspex Pharmaceuticals.

Teva currently carries a Zacks Rank #3 (Hold).
