LA JOLLA, Calif., Feb. 3, 2015 (GLOBE NEWSWIRE) -- Auspex Pharmaceuticals, Inc. (Nasdaq:ASPX), a biopharmaceutical company dedicated to developing innovative medicines for people with movement disorders and other rare diseases, today announced that it has completed target enrollment in its pivotal clinical trial of SD-809 for the potential treatment of tardive dyskinesia (TD), called ARM-TD (Aim to Reduce Movement in TD). The company expects to announce topline data from this study in mid-2015.
TD is a hyperkinetic movement disorder affecting about 500,000 people in the United States and is caused by widely used medications to treat psychiatric conditions such as schizophrenia and bipolar disease, as well as by certain drugs used for treating various gastrointestinal disorders.
“Tardive dyskinesia is a devastating and severely debilitating condition for many patients. There are no FDA-approved treatments for tardive dyskinesia, making the need to find a treatment all the more urgent,” said Michael Huang, M.D., vice president, clinical development, Auspex Pharmaceuticals. “Completing enrollment in this trial marks an important step forward in our understanding of the potential impact SD-809 may have on the lives of the approximately half-a-million people in the U.S. living with this disease.”
In ARM-TD, approximately 90 patients with moderate to severe TD were targeted for enrollment. Enrolled patients were randomized 1:1 to receive either SD-809 or placebo, which was titrated to optimal dosage over six weeks, and then administered that dose for another six weeks, for a total of 12 weeks of treatment. The primary efficacy endpoint is the change in the Abnormal Involuntary Movement Scale (AIMS) from baseline to end of therapy, as assessed by centralized video rating. The safety endpoints include adverse events, vital signs, physical/neurological/laboratory examinations and ECGs. Based on feedback obtained at a meeting with the U.S. Food and Drug Administration, the ARM-TD trial may qualify as one of the two pivotal trials needed for a 505(b)(2) New Drug Application (NDA) filing. Eligible subjects who complete the Phase 2/3 clinical trial are offered an option to rollover into a long-term safety study (RIM-TD).
“We are extremely pleased to have reached this critical milestone in the development of SD-809,” said Pratik Shah, Ph.D., president and CEO, Auspex Pharmaceuticals. “We look forward to reporting on the trial results and continuing to advance our entire SD-809 clinical program. We believe strongly in the potential of SD-809 to become the treatment of choice for this serious debilitating movement disorder.”
Auspex is also conducting an additional randomized, double-blind, placebo-controlled, parallel group pivotal clinical trial of SD-809 in approximately 200 people with tardive dyskinesia (AIM-TD; Addressing Involuntary Movements in Tardive Dyskinesia). Topline results from the AIM-TD trial are expected in 2016. Contingent upon successful completion of both the ARM-TD and AIM-TD studies, Auspex plans to file an NDA for SD-809 for the treatment of tardive dyskinesia in 2016.
